Use the formula A=(1+r/n)^nt to solve the compound interest problem.
Find how long it takes for 900$ to double if it is invested at 6% interest compounded monthly.
The money will double in value in approximately ? years.
(Do not round until the final answer. Then round to the nearest tenth as needed.)
The total years taken to double the money according to Compounding will be 12.5 years.
What is compound interest?
Compound interest is that the interest on savings calculated on each the initial principal and therefore the accumulated interest from previous periods.
Main body:
Given :
rate = 6%
amount = $900
Total amount = $1800
Compounded monthly,
so formula becomes,
Total amount = amount (1+r/1200)^12t
T = A[tex](1+r/1200)^{12t}[/tex]
1800 = 900 (1+6/1200)^12t
2 = (1+1/200)^12t
2 = 1.005^12t
taking log on both sides
log 2 = 12t *log 1.005
0.3/0.002 = 12t
t = 12.5 years
Hence the time taken to double the money is 12.5 years.

Find an equation for the parabola that has its vertex at the origin and satisfies the given condition. Directrix y=1/2
Required equation of the parabola with origin as its vertex and directrix
y = 1/2 is equal to x² = -2y.
As given in the question,
Let vertex of the parabola be ( h, k )
Vertex of the given parabola be at origin
⇒ ( h , k ) = ( 0 , 0 )
Directrix is y =1/2 above the vertex.
Focus is ( 0, -1/2)
Equation of the parabola is given by
Distance between focus to the vertex = distance between vertex to the directrix
( y - (1/2) )² = ( x - 0)² + ( y - (-1/2) )²
⇒ y² - y + 1/4 = x² + y² + y + 1/4
⇒ -y = x² + y
⇒x² = -y - y
⇒ x² = -2y
Therefore, the equation of the parabola with vertex at origin and directrix y =1/2 is equal to x² = -2y .

What is a one-variable linear equation and what does it look like?
The equation for a linear equation in one variable is written as ax+b = 0, where a and b are two integers, and x is a variable. This equation has only one solution. For instance, the linear equation 2x+3=8 only has one variable.
The initial formula is:
3x - 4 = 2x + 5
Four positive unit tiles are added to each side, giving us:
3x - 4 + 4 = 2x + 5 + 4
3x = 2x + 9
which removes the independent elements off both sides of the equal sign and places them all on the right side (the +9 term), simplifying the initial equation. You'll see that the other choices don't produce this outcome.

What is an exponent in math?An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.
here, we have,
We have to calculate to find the result -
The expression is = 4^(-3)/4^(-8)
According to the indices rule, the power will be deducted if it is a division.
Therefore, a^m/a^n = a^(m-n)
Using that formula,
4⁻³ / 4⁻⁸
= 4⁸ / 4³
= 4⁽⁸⁻³⁾
=4⁵
Therefore, the answer choice D is the option, and the answer is 4^5.
Option A is also correct.
Because we can find 4^5 with the help of that option.
Alternative way,
4^(-3)/4^(-8)
= 4^(-3+8)
= 4^(8-3)
= 4^8/4^3
In the is way, we can also find option A is correct.

Step-by-step explanation:
slope = 1-(-3)/3-1
4/2 = 2
this is the m value, or value before x.
So far, this is what we have: y = 2x + b
To find b, we plug in one of the points we have, into the equation.
(in this case ill use (3, 1), where 3 is the x and 1 is the y)
So,

Given:
(2,5) and (-4,2)
So, slope

Complete the table using equivalent ratios.
Willka covers 4.5 m² in 1L paint and 45 m² in 10L in paint according to the table.
What are equivalent ratios?
We know that the equivalent ratio is defined as the ratio which is having the same proportion as given ratio.
Now, using the division property of the ratio, we will divide the given ratio with the same number both sides.
According to the given question:
If Willka covers 13.5 m² with 3L paint, to cover x m² she will need 1L paint
By equivalent ratios
13.5 : 3 = x : 1
x = 13.5 / 3
x = 4.5
Similarly to cover y m² she needs 10L paint
13.5 : 3 = y : 10
y = 13.5 x 10/3
y = 45

A 33-m tall building casts a shadow. the distance from the top of the building to the tip of the shadow is 34m. Find the length of the shadow. If necessary, round your answer to the nearest tenth.
Answer:
8.2 m
Step-by-step explanation:
You want the length of the shadow whose tip is 34 m from the top of a 33 m building.
HypotenuseThe described geometry can be modeled by a right triangle with one leg 33 m and hypotenuse 34 m. The Pythagorean theorem tells us the length of the other leg is ...
a² +b² = c²
b² = c² -a²
b = √(c² -a²)
b = √(34² -33²) ≈ 8.2 . . . . meters
The length of the shadow is about 8.2 meters.
__
Additional comment
The angle of elevation to the top of the building can be found from the trig relation ...
Sin = Opposite/Hypotenuse
And the length of the shadow can be found from the relation ...
Cos = Adjacent/Hypotenuse
If α is the angle of elevation, then ...
sin(α) = 33/34 ⇒ α = arcsin(33/34)
and
Adjacent = Hypotenuse × cos(α)
Adjacent = 34·cos(arcsin(33/34)) ≈ 8.2 . . . . meters
where the "adjacent" side of the triangle is the side between the building and the tip of the shadow, along the ground.
If a fair coin is tossed 5 times, what is the probability, rounded to the nearest thousandth, of getting at most 2 heads?
