Answer:
40.56 ft
Step-by-step explanation:
The perimeter of a circle is equivalent to 
, where r = radius. Therefore, the perimeter of a semicircle should be 
In this case, we're given the diameter of the semicircle as 8, so we divide the diameter by 2 and get the radius as 4. Now, let's solve the circumference of the semicircle.
Now, we're given the lengths of the rectangle as 8, 10, and 10. The perimeter of the rectangle (excluding the inner side) is 28.
28 + 12.56 = 40.56
Therefore, the perimeter is 40.56 ft.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
The best answer would be C!
PLEASE GIVE ME THE BRAINLIEST I TRIED REALLY HARD ON THIS QUESITON!
use the quotient rule then after using it the first time use it again on your resulting equation, since you are looking for the second derivative
Answer: 6/7
Step-by-step explanation: Juts continue to divide the numerator and the demonator by the same number that can be divided into both to solve a fraction in the simplest form.
Answer:
- y = 1/4 x - 1
- y = 4x + 11
Step-by-step explanation:
It is probably easiest to identify the required slope so you can eliminate the bogus answers, then try the point in the remaining equations to see what works.
1. Parallel lines have the same slope. A line parallel to a line with slope 1/4 will also have slope 1/4, eliminating the 2nd and 4th answer choices.
Trying the point in the first answer choice, we have ...
-2 = (1/4)(-4) -1 . . . . true . . . . . y = 1/4x -1 is the correct equation
__
2. Perpendicular lines have slopes that are the negative reciprocal of each other. -1/(-1/4) = 4, eliminating the 2nd and 3rd choices.
Trying the point in the first answer choice, we have ...
7 = 4(-1) +3 . . . . . . false
The last answer choice gives ...
7 = 4(-1) +11 . . . . . . true . . . . . . y = 4x +11 is the correct equation
