Answer:
Area= 32 (formula is: length x width)
Perimeter= 8 + 4 + 8 + 4= 24
Step-by-step explanation:
Circumference=diameter times pi
diameter=12
circumference=12 times pi
we use pi=3.14
circumfernce=12 times 3.14
circumference=37.68 ft
round to tenth
8 is greater than 5 so roundup
37.7ft
I just took the test the correct answer is:
Amplitude = 3 feet; 3 period = 16 hours; midline: y = 5.
Answer:
11/9
Step-by-step explanation:
To find the slope
m = ( y2-y1)/(x2-x1)
= ( 9 - -2)/(1 - -8)
= ( 9+2)/ (1+8)
= 11/9
X/4 + 12 = 5
to isolate the variable the first step is to subtract 12 from both sides
x/4 + 12 - 12 = 5 - 12
x/4 = -7
next, to get rid of the division by 4, multiply both sides by 4
(x/4)*4 = -7*4
x = -28
