What equation matches the graph?
A. y = -3x + 1
B. y = -3x - 1
C. y = -2x + 1
D. y = -2x - 1
Answer:
A y = -3x + 1
Step-by-step explanation:
y = mx + b When need to know the m (slope) and the b (y-intercept
The b is where the line crosses the y axis. It crosses the y axis at 1. The slope tells us the steepness of the line.
If you start at the point (0,1) and move three units down and I unit to the right, you will be back on the line. The slope is -3/1 which simplifies to -3

What is volume of water?
The form of the container the water is contained in affects how much water is contained inside. You must know the length, breadth, and depth of a square or rectangular vessel in order to calculate its volume using the volume equation V=L*W*D, where L stands for length, W for width, and D for depth. The volume equation in this case reads: V= (r²)Dπ, where r stands for the radius, D for depth, and, or pi, is a constant value that is typically rounded to 3.14. To perform the same volume calculation for a circular vessel, you must know the vessel's depth and diameter or radius.
Given, the water park has water which is 8.6*10⁵ gallons.
We know that 10⁵ = 100000
Thus, 8.6*10⁵ = 860000
The new ride would use an additional 9.1*10⁴ gallons.
Again, 10⁴ = 10000
Thus, 9.1*10⁴ = 91000
Total water that would be required now is equal to the sum of the original water volume and the volume required by the new ride
= (860000+91000) gallons
= 951000 gallons
= 9.51*10⁵ gallons
Hence, the total gallons of water made use of in the park after the new ride is installed is 9.51*10⁵ gallons

You see from the graph that when x = 0, y = 2 so the y-intercept is ( 0 , 2).
you are given points (-5 , 6) and (5 , -2). Find slope:
slope = change in y / change in x
slope = (6 - (-2)) / (-5 - 5)
slope = (6 +2) / (-5 - 5)
slope = 8/-10
slope = -4/5
slope-intercept form: y = mx + b where m = slope and b = y intercept.

A museum is creating a simicircle statuary garden with a diameter of 26 feet. There will be a fence around the garden. The fencing costs $8.25 per linear foot. About how much will the fencing cost altogether.
Answer: $336.77
Step-by-step explanation:
So, the fencing is technically the perimeter, so we have to find the perimeter of the semicircle.
Perimeter of a semicircle = 2(pi)(r)/2
So, divide 26 by 2 to get the radius, which is 13.
(We will use 3.14 for pi)
Then fill in the variables 2 x (3.14) x (13) / 2
So, when you multiply all the numbers you will get 81.64/2.
81.64/2 = 40.82 ft.
Now that you have found how much feet the fencing will be, multiply it by the cost.
40.82 x 8.25 = 336.765.
Round your final answer by the nearest hundredth which is 336.77.

A quadrilateral has two angles that measure 140° and 70°. The other two angles are in a ratio of 4:11. What are the measures of those two angles?
Answer:
40° and 110°
Step-by-step explanation:
the sum of the 4 angles in a quadrilateral = 360°
the ratio of 2 angles = 4 : 11 = 4x : 11x ( x is a multiplier )
sum the 4 angles, equate to 360 and solve for x
140 + 70 + 4x + 11x = 360
210 + 15x = 360 ( subtract 210 from both sides )
15x = 150 ( divide both sides by 15 )
x = 10
Then
4x = 4 × 10 = 40°
11x = 11 × 10 = 110°
the measure of the 2 angles is 40° and 110°
Determine the coupon payments for the following three bonds: 5. 5% coupon corporate bond (paid annually), 6. 45% coupon treasury note, and a corporate zero-coupon bond maturing in 10 years. (assume $1,000 par value. ).
For the 5.5% coupon corporate bond, the coupon payment would be $55 per year. For the 6.45% coupon treasury note, the coupon payment would be $64.50 per year.
What is Percentage?Calculations using percentages show how much a given number contributes to the total. It is computed by dividing the number by the sum and multiplying by 100. It is denoted by the sign "%." For example, if a basket contains ten apples, three of which are red, the proportion of red apples in the basket is 30% (3/10 x 100). In a wide range of disciplines, including business, statistics, and education, percentage is often utilized. Calculating interest rates, taxes, and other financial activities in the finance industry annually frequently uses percentages. The frequency of events or the likelihood of a certain outcome are both measured using this method in statistics. Calculating grades and evaluating a student's overall performance are both done using this in education.
How to solve?
For the 5.5% coupon corporate bond, the coupon payment would be 5.5% of $1,000 = $55 per year.
For the 6.45% coupon treasury note, the coupon payment would be 6.45% of $1,000 = $64.50 per year.
For the corporate zero-coupon bond maturing in 10 years, there are no coupon payments. The bond will only make a payment of $1,000 at maturity.

The following expression represents a 2-scale factor vertical stretch, a transformation of 4 units left, and a transformation of 1 unit down:
g(x) = 2f(x + 4) - 1
How to write the given transformation?A vertical stretch of scale factor K is expressed as follows for the general function f(x):
g(x) = Kf(x).
Horizontal translation:
A horizontal translation of N units for a general function f(x) is written as:
g(x) = f(x + N).
The shift is to the left if N is positive and the shift is to the right if N is negative.
Vertical translation:
A vertical translation of N units for a generic function f(x) is expressed as follows:
g(x) = f(x) + N.
When N is positive, there is an upward movement and N shifts downward if it is negative.
So, if we start with a function f(x) and we stretch it vertically with a scale factor of 2, we get:
g(x) = 2f(x)
Then we translate it into 4 units left:
g(x) = 2f(x + 4)
Then we translate 1 unit down:
g(x) = 2f(x + 4) - 1
This is the equation for the transformation.

Step-by-step explanation:
find the particular solution of the differential equation that satisfies the initial condition(s). f '(s)
Particular solution of the differential equation that satisfies the initial condition f'(s) = 10s - 4s³ , f(3) = 5 is f(s) = 5s² - s⁴ + 41.
We determine the particular solution to the differential equation. We do this by integrating the given differential equation and then applying the given initial condition. The power rule should be used for the given expression.
[tex]\int\ {x^{a} } \, dx[/tex] = [tex]\frac{x^{a+1} }{a+1} }[/tex]
we have given that,
f'(s) = 10s - 4s³
f(s) = ∫ f'(s)ds
= ∫(10s - 4s³)ds
= [tex]\frac{10s^{2} }{2} - \frac{4s^{2} }{4}+ C[/tex]
f(s) = 5s² - s⁴ + C
Now we will apply the initial condition,
f(3) = 5
⇒5(3)² - (3)⁴ + C =5
-36 + C = 5
C =41
Therefore the solution is expressed as,
f(s) = 5s² - s⁴ + 41
This is the particular solution.
