Answer:

Area = 51.89cm^2

Step-by-step explanation:

The- region- is- a -segment\\r = 7cm\\\alpha = 150\\A = \frac{\alpha }{360} \times \pi r^2 -\frac{1}{2} \times r^2Sin\alpha \\\\A = \frac{150}{360} \times 3.142 \times7^2 -\frac{1}{2} \times 7^2  \times Sin 150\\A =5/12 \times 3.142 \times49- (1/2\times 49 \times1/2)\\A = 64.149-49/4\\A = 51.89

Aleksandr [31]
So remember that paralell lines have the same slope
y=1/4x-6
1/4=slope
so we set up a new equation in slope intercept form
y=mx+b
m=slope
b=y-intercept

y=1/4x+b

one solution si (-1,5) where x=-1 and y=5
subsitute
5=1/4(-1)+b
5=-1/4+b
add 1/4 to both sides
5+1/4=21/4=b

the answer is y=1/4x+21/4

Answer:

y = 1/5x - 7/5

Step-by-step explanation:

y = 1/5x + b

-1 = 1/5(2) + b

-1 = 2/5 + b

-7/5 = b

Answer:

so does this go with what you got I would think C correct me if i'm wrong

Step-by-step When a population or group of something is declining, and the amount that decreases is proportional to the size of the population, it's called exponential decay. In exponential decay, the total value decreases but the proportion that leaves remains constant over time.
