Hello!
Recall that the transformations form of a parabola is:
f(x) = ±a(b(x-h)) + k where:
a = vertical stretch/compression
b = horizontal stretch/compression
h = horizontal shift, x-coordinate of vertex
k = vertical shift, y-coordinate of vertex
In this instance, the parent function is f(x) = 3x^2. There is a vertical stretch of 3.
However, there is a point (7, -2) that needs to be included. Substitute these values into the transformation formula:
h = 7
k = -2
f(x) = 3(x - 7)² - 2 is the equation with (7, -2) as the vertex.
12=2.55 how about 8
8 x 2.55 divided by 12=$1.7
Answer: 8
Step-by-step explanation: As the woman is not looking and assuming that the probability of taking a red ball is the same of a blue ball, she must select 8 balls to be sure she has at least 3 blue balls.
Because at the case of selecting 5 red balls in the first 5 selects and to have at least 3 blue ones in her hand, she will select the third blue ball at selection number 8.
Answer:
y = -x - 8
Step-by-step explanation:
First, calculate the slope:
m = 
(x₁, y₁) will be (8, -16)
(x₂, y₂) will be (6, -14)
Plug in values:
m = 
simplify:
m = 
m = -1
plug values into y = mx + b:
-16 = (-1)(8) + b
solve for b:
b - 8 = -16
b = -8
rewrite the equation:
y = -1x - 8
y = -x - 8
Answer:
A table
Step-by-step explanation:
A table has four legs ( supports) but cannot possibly walk because it is not a living thing. For example, see the table in the attachment, it has four legs (supports) but cannot possibly walk.
