Answer:
D and F
Step-by-step explanation:
r: m=-2 y=1 y = -2x + 1
s: m=2 y=1 y = 2x + 1
t: m=1/2 y=1 y = 1/2x + 1
slope of r x slope of t = -2 x 1/2 = -1 (r and t is perpendicular)
all 3line have the same y intercept (0,1), they are not possible to be parallel
Answer: Choice B) multiply the radius by 2, then by 3.14
The formula is
C = 2*pi*r
which you can rearrange to get C = 2*r*pi, showing you multiply 2 and the radius r, then multiply by pi = 3.14 which is approximate
A similar related formula is
C = pi*d
where d is the diameter. Note that d = 2*r, so we can replace d with 2r to get the first formula back again.
the circumference is the distance or perimeter around the circle

Solution :
Transforming given equations :
![1)\ P = 600( 1 + \dfrac{12}{100})^t\\\\2)\ P = 1000( 1 + \dfrac{3}{100})^t\\\\3)\ P = 200( 1 + \dfrac{8}{100})^t\\\\4)\ P = 900( 1 - \dfrac{10}{100})^t](https://tex.z-dn.net/?f=1%29%5C%20P%20%3D%20600%28%201%20%2B%20%5Cdfrac%7B12%7D%7B100%7D%29%5Et%5C%5C%5C%5C2%29%5C%20P%20%3D%201000%28%201%20%2B%20%5Cdfrac%7B3%7D%7B100%7D%29%5Et%5C%5C%5C%5C3%29%5C%20P%20%3D%20200%28%201%20%2B%20%5Cdfrac%7B8%7D%7B100%7D%29%5Et%5C%5C%5C%5C4%29%5C%20P%20%3D%20900%28%201%20-%20%5Cdfrac%7B10%7D%7B100%7D%29%5Et)
From above equations we can see that equation 1) has largest percentage growth rate and the percent growth rate is 12% .
Hence, this is the required solution.
