Lunna [17]

Answer:

Step-by-step explanation:

$\text{The vertex form of an an equation of a quadratic function:}\\\\y=a(x-h)^2+k\\\\(h,\ k)-vertex\\\\\text{We have}\ g(x)=(x-h)^2+k,\ \text{and the vertex in}\ (9,\ 8).\\\\\text{Therefore}\ h=9\ \text{and}\ k=8.\ \text{substitute:}\\\\g(x)=(x-9)^2+8$

I found the image that accompanied this problem.
We need to solve for the area of the sector.

A = n/360 * π * r²
A = 85/360 * 3.14 * 5²
A = 0.2361 * 3.14 * 25
A = 18.5347

Answer is C. 18.5 square meters.

12. Linda walks through a road. If her walking speed increases from 1 m/s to 1.5 m/s, she will complete the walk 200 s earlier.

Katen [24]

Answer:

600 meters

Step-by-step explanation:

Case 1 : Speed of 1 m/s

d = v * t
d = 1 * t
d = t [Equation 1]

Case 2 : Speed of 1.5 m/s

d = v * t
d = 1.5 * (t - 200)
d = 1.5t - 300 [Equation 2]

As distance in both cases is the same, equate the values of d from both equations.

t = 1.5t - 300
0.5t = 300
t = 300 * 2
t = 600 s

Now, put the value of t in Equation 1 to find d.

d = 600 meters
