Answer:
Step-by-step explanation:
10+10=20
8+8 = 16
36 is perimeter of the rectangle
diameter of half circle is 8
formula for circumference of a circle is r π = 8 x 3.14
8 x 3.14 = 25.12 but your not done yet its a half circle so divide by 2
25.12/2 = 12.56
12.56 + 36 = 48.56 is final answer

Answer:
–16 – 22i
Step-by-step explanation:
The radius of the circle = 4 + 26i - (-6 + 2i)
= 10 + 24i.
The radius will be the absolute values of this |10 + 24i|.
If a point is on the circle then it's distance from the centre must be 10+ 24i.
-19 + 15i - (-6 + 2i) = -13 - 13i , so this is not on the circle.
-16 - 22i - (-6 + 2i) = -10 - 24i = |10 + 24i| , so this is on the circle.
5 + 16i - (-6 + 2i) = 11 + 14i , so this is not on the circle.
20 - 24i - (-6 + 2i) = 26 - 26i. so this is not on the circle.
Answer:
B) 12.5 ft
Step-by-step explanation:
set up a proportion of inches/feet equals inches/feet
let 'h' = height of sign
5.4/18 = 3.75/h
cross-multiply:
5.4h = 67.5
h = 12.5
First of all, you would use the FOIL method for -5(a + 3). This means to just multiply -5 to all of the values in the parenthesis. This would equal:
-5a -15 = -55
Then after, you would add 15 for both sides and get -5a = -40
Divide by -5 on both sides, you get a = 8.
