Answer: C
In vertex form a(x - h)2 + k, values of a indicate the horizontal stretch/compression. From there just knowing that values less than 1 stretch the graph, while values greater than 1 compress it. Graphing it out on your own by simply inputting values into x will make this pretty clear.

The point (-3, 2) lines on a circle whose equation is (x + 3)2 + ( + 1)2 = r2. Which of
the following must be the radius of the circle?
Answer:
3 units
Step-by-step explanation:
Equation of the circle is:
[tex] (x+3)^2 +(y+1)^2=r^2 [/tex]
[tex] \therefore [x-(-3)] ^2 +[(y-(-1)] ^2=r^2 [/tex]
Equating it with
[tex] (x-h)^2 +(y-k)^2=r^2 [/tex]
We find: h = - 3 & k = - 1
Center of the circle (C) = (-3, - 1)
Since, the point (-3, 2) lies on the circle, therefore radius of the circle wii be equal to the distance between the center of the circle (-3, - 1) and the point (-3, 2) which is on the circle.
Therefore,
[tex] r = \sqrt{[-3-(-3)]^2 +[2-(-1)]^2} [/tex]
[tex] r = \sqrt{[-3+3]^2 +[2+1]^2} [/tex]
[tex] r = \sqrt{[0]^2 +[3]^2} [/tex]
[tex] r = \sqrt{0 +9} [/tex]
[tex] r = \sqrt{9} [/tex]
[tex] r = 3\: units [/tex]
A savings account starts with $980 at a simple interest rate of 5.5%. How much interest will the account earn in 3 years?
Answer:
Interest = $161.70
Step-by-step explanation:
Formula:
I = Prt
Given:
P = 980
r = 0.055
t = 3
Work:
I = Prt
I = 980(0.055)(3)
I = 53.9(3)
I = 161.7

What is the value of x in this equation?
8x + 40 = 180
Answer:
17.5
Step-by-step explanation:
180 = 40+ 8x
140 = 8x
17.5 = x
Answer:
17.5 is the correct answer to the question
Step-by-step explanation:
8x+40=180
8x=180-40
8x=140
X=140/8

a plumber charges $15 for a service call plus $20 per hour of service. Write an equation in slope-intercept form for the cost, y, after x hours of service. What will be the total cost for 8 hours of work?
Answer:
C= 25$ + 50$ * h
8 hours 425$
10 hours 525$
Step-by-step explanation:
Answer:
y = 20x + 15
The total cost for 8 hours of work will be $175
Step-by-step explanation:
To find the total cost for 8 hours of work, substitute the x in the equation with 8, and solve. 20 times 8 is 160. 160 + 15 is 175.

What is 3% of 1700
Can you please explain the method please
Answer:
3% of 1700 is 51
Step-by-step explanation:
3% is the same thing as 0.03 so when you find a percentage of something, you multiply that number by the percentage. In this case, it is 3% of 1700 so you multiply 1700 by 0.03 to get your final answer of 51.

Answer:
y = -2x + 3
Step-by-step explanation:
Let's just put the three points together.
(-1, 5) (-4, 11) (-7, 17)
First, let's find the slope with y2 - y1/x2 - x1
Plug in using (-1, 5) and (-4, 11)
11 - 5/-4 + 1 = 6/-3 (simplify)
-2 is the slope
Now plug in (-7, 17) in the equation to get b or the y-intercept)
y = mx + b
17 = -2(-7) + b
17 = 14 + b (subtract 14 on both sides)
3 = b
y = -2x + 3

Answer:

Step-by-step explanation:
320 = 30x + 20
300 = 30x
x = 10
Answer:
10 hours
Step-by-step explanation:
We already have the equation, which is y = 30x + 20. Simply substitute 320 for y, and solve for x.
320 = 30x + 20
First, subtract 20 from both sides.
320 - 20 = 30x
300 = 30x
Now divide both sides by 30.
300/30 = x
10 = x

find the product of 10.2 and 6.3
Answer:
10.2*6.3=64.26
Step-by-step explanation:
Solve 102*63, then move the decimal point two numbers from the right:
Since 102*63=6426, then moving the decimal point two numbers from the right will mean 10.2*6.3=64.26
Answer:
64.26
Step-by-step explanation:
This is a simple multiplication
When you 'multiply' or 'times' even a product of a number you add it to itself a number of times, for this problem, 10.2 multiplied by 6.3 is the same as saying 10.2 + 10.2 + 10.2 = 64.26. Multiplication is therefore a quicker way of adding the same number many times, for example, 10.2 × 6.3 = 64.26. Therefore, the product of 10.2 and 6.3 is 64.26.
Volunteers at a food pantry pack boxes of soup into crates. How many boxes of soup will fill each crate? Show your work.
Answer:
54 boxes
Step-by-step explanation:
Dimension of crate = 12 in by 18 in by 12 in
Volume of crate = (12 * 18 * 12) = 2592 in³
Dimension of box = 4 in by 2 in by 6 in
Volume of box = (4 * 2 * 6) = 48 in³
Number of boxes of soup that will fill each crate :
Volume of crate / volume of box
2592 in³ / 48 in³
= 54 boxes
find the volume of the figure please.
Answer:
Step-by-step explanation:
area of side face=(37+15)/2 ×25.7=26×25.7 cm²
volume=26×25.7×20=13364 cm³

Calculate the volume of the cylinder giving your answer to 1 decimal. Picture linked. Please I have a math test tomorrow I'll give extra points for explanation!!!
Answer:
549.5 cm³
Step-by-step explanation:
___________________________________________________________
FORMULA USED IN THE QUESTION :-
Volume of a cylinder whose height is 'h' and radius is 'r' = [tex]\pi \times r^2 \times h[/tex]
___________________________________________________________
According to the question ,
Height of cylinder (h) = 7 cm
Radius of cylinder (r) = 5 cm
Volume of cylinder = [tex]\pi \times 5^2 \times 7 = 3.14 \times 25 \times 7 = 549.5 \: cm^3[/tex]
