Answer:
160π/3 units² ≈ 167.55 units²
Step-by-step explanation:
The appropriate area formula is ...
A = (1/2)r²θ
Filling in the numbers, you have ...
A = (1/2)(8²)(5π/3) = 160π/3 ≈ 167.55 . . . . square units
Answer:
slope = - 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 1, 4) and (x₂, y₂ ) = (2, 1)
m = 
= 
= - 1
Answer:
Step-by-step explanation:
25.
Combine like terms.
4t+7=-33
subtract 7 from both sides
4t=-40
divide both sides by 4
t=-10
26.
Subtract 2a from both sides
5=7a-16
add 16 to both sides
21=7a
divideby 7 on both sides
a = 3
