F(-5) just means that your substituting the number -5 for every x value. So if you have x+1 this would be -5+1 which is -4

6. Answer:
72.84
Step-by-step explanation:
To find the perimeter of the rectangle, just add the sides together except the one connected to the semicircle
12 + 15 + 15 = 42
The diameter of the semi circle is 12
πr + d = 6 * π + 12 ≈ 30.84
Add them together
42 + 30.85 = 72.84
7. Answer:
78.54
(78.5)
Step-by-step explanation:
The shape is a circle
Radius is 5
Diameter is 10 (diameter is always double of the radius)
π * r^2 = π * 25 cm^2 = 78.54 cm^2
8. Answer:
50.27
Step-by-step explanation:
The shape is a circle
Radius is 4
Diameter is 8 (diameter is always double of the radius)
π * r^2 = π * 16 ft^2 = 50.27 ft^2
(16 = 8 * 2)
A=.5*r^2*theta
a=p
2.5q=2pi(r)
2pi(r)=.5(r^2)(2pi)
1=.5r
2=r
Answer:
15 = 9 + 5j
Step-by-step explanation:
When you want to make words become an equation, the word <em>is</em><em> </em>usually means <em>= </em>and <em>more</em><em> </em>usually means <em>+</em>.
In this case, we have 15 is 9 more than 5j.
We can rewrite this as 15 = 9 + 5j.
