Answer:
1.18x=y
Step-by-step explanation:
x= amount of pounds of kidney beans
y= the cost
The equation of the function in vertex form is y = -(x + 5)² + 4
<h3>What is quadratic equation?</h3>
A quadratic equation is a second-order polynomial equation in a single variable x , ax2+bx+c=0. with a ≠ 0 .
Given that the quadratic function has roots at -3 and -7 and a vertex at (-5,4).
We need to find the equation of the function in vertex form
equation of the function in vertex form.
As per the information given in the question,
The given roots of the function are -3 and -7,
y = a (x + 3) (x + 7)
y = a (x² + 10x + 21)
y = a (x² + 10x + 25 − 4)
y = a (x² + 10x + 25) − 4a
y = a (x + 5)² − 4a
The vertex is (-5, 4),
So, a = -1.
y = -(x + 5)² + 4
Hence, y = -(x + 5)² + 4 is the equation of the function in vertex form

I believe the correct answer is A. 0.87
On any given day, the probability that a person chosen at random will visit either Willow Creek or Two Harbors is <span>0.87
How did I get this?
62% = 0.62 73% = 0.73 48% = 0.48
( 0.62 + 0.73 ) - 0.48
*Sorry had to correct it I did the math again and got 0.87*</span>
Answer:
<QRP = 48.2°
Step-by-step explanation:
Given:
PR = 18 cm
QR = 12 cm
Required:
<QRP = angle R
Solution:
Reference angle = <R (<QRP)
Adjacent side length = 12 cm
Hypotenuse = 18 cm
Thus:
Cos (R) = 12/18
cos (R) = 0.6667
<QRP = 48.2° (nearest tenth)
