What are index ?
An index can be assigned to a number or variable. A value raised to the power of a variable's (or a constant's) value is its index. The exponents or powers are other names for the indices. It displays how many times a particular number must be multiplied. It takes the following form:
a(m) = a × a × a ×……× a (m times)
The base in this case is a, and the index is m.
The index instructs a certain integer (or base) to be multiplied by itself a specified number of times, where the number of times is determined by the index raised to the base. It is a condensed way of expressing large sums of information and calculations.

Answers
The estimated price of a new car in 4 years time if the inflation rate is 12.3% is 393050
What is meant by inflation rate?In economics, "inflation" refers to a significant increase in the price of goods and services throughout an economy. This is why growing prices often cause inflation. Deflation, which is a sustained decline in the average level of prices for goods and services, is the reverse of inflation. The most common measure of inflation is the annualized percentage change in an index of general prices, also known as the inflation rate.
Given,
The cost of the car bought by a women=350000
Time=4 years
And inflation rate=12.3%
We know that,
Inflation rate=((B-A)/A)×100
Here A denotes the standing price
So, A=350000
B denotes estimated price
So, B=x
12.3=((B-350000)/350000)×100
43050=B-350000
B=393050
Therefore, the estimated price of a new car in 4 years time if the inflation rate is 12.3% is 393050.

What is an isosceles triangle?An isosceles triangle is a type of triangle that has any two sides equal in length. The two angles of an isosceles triangle, opposite to equal sides, are equal in measure. In geometry, triangle is a three-sided polygon that is classified into three categories based on its sides, such as:
Scalene triangle (All three sides are unequal)
Isosceles triangle (Only two sides are equal)
Equilateral triangle (All three sides are equal)
Find attachment to understand the explanation
∠A = ∠C ( base angles of an isosceles triangle)
∠A = x and ∠C = 76
Therefore ∠X = 76°
For diagram 6
interior ∠A + exterior ∠A = 180°
but exterior ∠A = 110°
interior ∠A = 180 - 110
interior ∠A = 70°
∠A = ∠C( base angles of isosceles ΔBAC) which is 70°
∠A + ∠B + ∠c = 180
∠B = 180 - 70 - 70
∠B = 40°
but ∠CBA + ∠CBD = 90 because ∠B = 90° and ∠CBA = 40°
∠∠CBD = 90 - 40
∠CBD = 50°
But ∠∠CBD = ∠BDC( base angles of isosceles Δ)
so that
∠BCD + ∠CBD + ∠BDC = 180°( angles in a triangle)
x + 50 + 50 = 180
x = 180 - 100
x = 80°
In conclusion the value of x in the first and second diagrams are 76° and 80° respectively

A racetrack charges $85 for each seat in the lower section, $60 for each seat in the upper sections, and $35 for field tickets. There are three times the amount of seats in the upper section as compared to the lower section. The revenue from selling all 22,800 seats is $948,000. How many seats are in the upper section of the racetrack?
Answers
Based on a system of equations, the number of seats in the upper section of the racetrack is 3,600.
What is a system of equations?A system of equations or simultaneous equations is two or more equations concurrently or simultaneously solved.
There are four methods for solving simultaneous equations:
MatrixGraphicalEliminationSubstitution.The charge per lower-section seat = $85
The cost per upper-section seat = $60
The fee per field ticket = $35
Let the number of lower-section seats = x
Let the number of upper-section seats = 3x
Let the number of field tickets = y
Equation 1: x + 3x + y = 22,800 or 4x + y = 22,800
85x + 60(3x) + 35y = 948,000
Equation 2: 85x + 180x + 35y = 948,000
From equation 1, y = 22,800 - 4x ...Equation 3
Substitute Equation 3 in Equation 2 to eliminate y:
85x + 180x + 35(22,800 - 4x) = 948,000
85x + 180x + 798,000 - 140x = 948,000
125x = 948,000 - 798,000
125x = 150,000
x = 1,200
The number of seats for each racetrack section:
Lower section seats, x = 1,200
Upper section, 3x = 3,600 (1,200 x 3)
Field tickets, y = 22,800 - 4x
y = 22,800 - 4(1,200)
= 18,000
Check:
85x + 180x + 35y = 948,000
85(1,200) + 180(1,200) + 35(18,000) = 948,000
102,000 + 216,000 + 630,000 = 948,000
948,000 = 948,000
Total revenue:
Lower section seats = $102,000 (85 x 1,200)
Upper section seats = $216,000 (60 x 3 x 1,200)
Field tickets = $630,000 (35 x 18,000)
Total revenue = $948,000
Thus, based on simultaneous equations, we can conclude that there are 3,600 seats in the upper section.

The second one includes 1 small tier and 5 medium tiers, which is enough servings for 247 guests. How many guests does each size of tier serve.. ?
Answers
Answer:
Step-by-step explanation:
3 small tiers + 5 medium tiers= 291 guests
1 small tier+5 medium tiers=247 guests
The 2 cakes have the same medium tiers(5 medium tiers). If we subtract 291-247 we will have the number of guest that 2 small tiers serve.
291-247= 44 guests serve per 2 small tiers
44:2=22 guests serve per one small tier.
So if we subtrack the number of guest that one small tier one the cake that has only one small tier we will obtain the number of guests that the 5 medium tiers serve.
247-22=225 guests serve per 5 medium tiers
225:5= 45 guests per 1 mediem tier.
Answer:45 guests serve in a medium tier22 guests serve in a small tier.Sorry, because english isn't my mother tongue.

Step-by-step explanation:
[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]
Given equation:
[tex]5x-4y=1[/tex]
Rewrite in slope-intercept form:
[tex]\implies 5x-4y+4y=1+4y[/tex]
[tex]\implies 5x=1+4y[/tex]
[tex]\implies 5x-1=1+4y-1[/tex]
[tex]\implies 5x-1=4y[/tex]
[tex]\implies \dfrac{5}{4}x-\dfrac{1}{4}=\dfrac{4y}{4}[/tex]
[tex]\implies y=\dfrac{5}{4}x-\dfrac{1}{4}[/tex]
Therefore, the slope of the line is ⁵/₄.
If two lines are perpendicular to each other, their slopes are negative reciprocals.
Therefore, the slope of the perpendicular line is -⁴/₅.
Substitute the found slope -⁴/₅ and given point (1, -6) into the slope-intercept formula and solve for b:
[tex]\implies -6=-\dfrac{4}{5}(1)+b[/tex]
[tex]\implies -6=-\dfrac{4}{5}+b[/tex]
[tex]\implies b=-\dfrac{26}{5}[/tex]
Therefore, the equation of the perpendicular line in slope form is:
[tex]y=-\dfrac{4}{5}x-\dfrac{26}{5}[/tex]
[tex]\boxed{\begin{minipage}{5.5 cm}\underline{Standard form of a linear equation}\\\\$Ax+By=C$\\\\where:\\ \phantom{ww}$\bullet$ $A, B$ and $C$ are constants. \\ \phantom{ww}$\bullet$ $A$ must be positive.\\\end{minipage}}[/tex]
Multiply both sides of the equation in slope form by 5:
[tex]\implies y \cdot 5=-\dfrac{4}{5}x\cdot 5-\dfrac{26}{5}\cdot 5[/tex]
[tex]\implies 5y=-4x-26[/tex]
Add 4x to both sides:
[tex]\implies 5y+4x=-4x-26+4x[/tex]
[tex]\implies 4x+5y=-26[/tex]
Therefore, the equation of the perpendicular line in standard form is:
[tex]4x+5y=-26[/tex]
Carter invested $70,000 in an account paying an interest rate of 1.125% compounded continuously. Savannah invested $70,000 in an account paying an interest rate of 1.375% compounded quarterly. To the nearest dollar, how much money would Carter have in his account when Savannah's money has doubled in value?
Answers
Step 1: Figure out when Savannah will double her account value:
We need to solve [tex]140000 = 70000\left(1+\frac{0.01375}{4}\right)^{4t}[/tex].
Divide by 70000:
[tex]2 = \left(1+\frac{0.01375}{4}\right)^{4t}[/tex]
Take the natural log of both sides and bring the exponent down:
[tex]\ln(2) = 4t\cdot\ln\left(1+\frac{0.01375}{4}\right)[/tex]
Divide by that mess multiplied by t:
[tex]\dfrac{\ln(2)}{4\ln\left(1+\frac{0.01375}{4}\right)} = t[/tex]
Throw that into a calculator and you get about 50.497297884.
Depending on how picky your teacher is, we'd need to round this to the next time the interest is compounded, since it's only compounded each quarter, so t = 50.5. (The fact is that Savannah's account will never exactly double in value.)
Step 2:
Now, we need to evaluate Carter's continuously compounded investment for 50.5 years:
[tex]B = 70000e^{0.01125\cdot(50.5)}\approx123546.825994[/tex]
B ≈ 123547 to the nearest dollar.
As a comparison, here's the other calculation with the more precise t value.
[tex]B = 70000e^{0.01125\cdot(50.497297884)}\approx123543.070375[/tex]
B ≈ 123543 to the nearest dollar.
Again, I would say the 50.5 calculation is actually more correct, since Savannah's account only compounds the interest each quarter, but you'll have to decide what your teacher would say.
Answer:
$123,543 (nearest dollar)
Step-by-step explanation:
Find the length of time Savannah has to invest her money for it to double.
[tex]\boxed{\begin{minipage}{8.5 cm}\underline{Compound Interest Formula}\\\\$ A=P\left(1+\frac{r}{n}\right)^{nt}$\\\\where:\\\\ \phantom{ww}$\bullet$ $A =$ final amount \\ \phantom{ww}$\bullet$ $P =$ principal amount \\ \phantom{ww}$\bullet$ $r =$ interest rate (in decimal form) \\ \phantom{ww}$\bullet$ $n =$ number of times interest is applied per year \\ \phantom{ww}$\bullet$ $t =$ time (in years) \\ \end{minipage}}[/tex]
Given:
A = $140,000P = $70,000r = 1.375% = 0.01375n = 4 (quarterly)Substitute the given values into the formula and solve for t:
[tex]\implies 140000=70000\left(1+\dfrac{0.01375}{4}\right)^{4t}[/tex]
[tex]\implies 140000=70000\left(1.0034375\right)^{4t}[/tex]
[tex]\implies2=\left(1.0034375\right)^{4t}[/tex]
[tex]\implies \ln2=\ln\left(1.0034375\right)^{4t}[/tex]
[tex]\implies \ln2=4t\ln\left(1.0034375\right)[/tex]
[tex]\implies t=\dfrac{\ln 2}{4 \ln\left(1.0034375\right)}[/tex]
[tex]\implies t=50.49729788[/tex]
Therefore, it would take approximately 50.5 years for Savannah's principal investment to double.
[tex]\boxed{\begin{minipage}{8.5 cm}\underline{Continuous Compounding Formula}\\\\$ A=Pe^{rt}$\\\\where:\\\\ \phantom{ww}$\bullet$ $A =$ final amount \\ \phantom{ww}$\bullet$ $P =$ principal amount \\ \phantom{ww}$\bullet$ $e =$ Euler's number (constant) \\ \phantom{ww}$\bullet$ $r =$ annual interest rate (in decimal form) \\ \phantom{ww}$\bullet$ $t =$ time (in years) \\ \end{minipage}}[/tex]
Given:
P = $70,000r = 1.125% = 0.01125t = 50.49729788...Substitute the given values into the formula along with the found value of t and solve for A:
[tex]\implies A=70000e^{0.01125 \times 50.4972...}[/tex]
[tex]\implies A=123543.0704...[/tex]
Therefore, the amount of money that Carter would have in his account when Savannah's money has doubled in value is $123,543 (nearest dollar).

C(7,5) = 7! / (5! * 2!) = 7*6/2 = 21
This figure indicates that there are 21 alternative ways that the five days we want to be allocated in the seven days could be used.
The likelihood of each event is now:
5 days of song playback: (0.15)5
The song wasn't played for two days: (0.85)2.
Therefore, the final likelihood is
P =(0.15)^5*C(7,5) * (0.85)^2 = 0.001

Find X
Round to the nearest tenth.
Answers
Answer:
83 degrees
Step-by-step explanation:
17^2 = 8^2 + 16^2 - 2 * 8 * 16 * cos (X)
289 = 64 + 256 - 16 * 16 * cos(X)
289 = 320 - 256 cos(X)
289-320 = -256 cos(X)
- 31 = -256 cos(X)
31 = 256 cos(X)
31/256 = 256/256 cos(X)
0.121094 = cos (X)
x = arccos 0.121094
x = 83.04475538

Which expression represents the volume of the cone, in
cubic units?
Ο πχ
O 27x³
7x3
Answers
The volume of a cone is given by the formula:
V = (1/3) * π * r^2 * h
Where V is the volume, r is the radius of the base, and h is the height of the cone.
In this case, the base diameter and the height of the cone are both equal to x units, so the radius of the base is x/2 units. Therefore, the volume of the cone is:
V = (1/3) * π * (x/2)^2 * x
= (1/3) * π * x^3 / 4
= (π/4) * x^3
The correct expression for the volume of the cone is therefore O πx^3.
The expression that represents the volume of the cone in cubic units is:
V = (1/12) π x³
What is a cone?It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.
The volume of a cone is 1/3πr²h
We have,
The volume of a cone can be calculated using the formula:
V = (1/3) πr²h
where r is the radius of the base and h is the height.
Since the diameter of the base is equal to x, the radius is equal to half the diameter, which is x/2.
Also, we know that the height of the cone is also equal to x.
Substituting these values into the formula, we get:
V = (1/3)π (x/2)² x
Simplifying this expression, we get:
V = (1/3)π(x²/4)x
V = (1/12)πx³
Therefore,
The expression that represents the volume of the cone in cubic units is:
V = (1/12) π x³

Based on given question question, following are the answers of blanks based on Midpoint Theorem.
- ∠ECD ≅ ∠BCA [Vertically opposite angle]- ∠D ≅ ∠A [Alternate interior angle]Given, ∠DEC ≅ ∠ABCC is the midpoint of D and A1.) Definition of midpoint
The midpoint theorem states that the line segment joining the midpoints of any two sides of a triangle is parallel to the third side and equal to half of the third side.
2.) ∠ECD ≅ ∠BCA [Vertically opposite angle]
Vertical angles are a pair of non-adjacent angles formed by the intersection of two straight lines. In simple words, vertical angles are located across from one another in the corners of the "X" formed by two straight lines. They are also called vertically opposite angles as they are situated opposite to each other.
3.) ∠D ≅ ∠A [Alternate interior angle]
When two parallel lines are crossed by a transversal, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. These angles are always equal.

9) 7 Divided by 292 plssss help
Answers
The value when 7 is divided by 292 is given as 0.023972(approximation)
What is division ?One of the fundamental mathematical operations is division, which involves breaking a bigger number into smaller groups with the same number of components. How many groups will be created, for instance, if 30 students need to be separated into groups of five for a sporting event? The division operation may be used to quickly and simply fix such issues. In this case, we must divide 30 by 5. 30 x 5 = 6 will be the outcome. There will thus be 6 groups with 5 students each. The initial number, 30, which is obtained by multiplying 6 by 5 may be used to confirm this figure.
The names of the phrases connected with the division process are referred to as division parts. The division is made up of the following four components: dividend, divisor, quotient, and remainder.
In the problem 7 is the Dividend and 292 is the divisor so
[when we add decimal 0 is added to the number and for each 0 in the quotient 0 is also added to the number if the zero is after the decimal]
