Given:
Area of a sector = 
Radius = 5 cm
To find:
The central angle.
Solution:
The area of a sector is:

Where, r is the radius and
is the central angle in radians.
Putting
in the above formula, we get

Multiply both sides by 2.

Divide both sides by 25.


Therefore, the central angle in radians is
.
Answer: x = 8
Step-by-step explanation:
8(3-2x) + 4(3x - 2) = -16
expanding the equation , we have
24 - 16x +12x - 8 = -16
16 - 4x = -16
collecting the like terms
4x = 32
x = 32/4
x = 8
Yes, because the whole number 36 is greater than 0.
Answer:
the answer is number two
Step-by-step explanation:
Step-by-step explanation:
F(x) = ∫ₐˣ t⁷ dt
F(x) is the area under f(t) between t=a and t=x. When x=a, the width of the interval is 0, so the area is zero.
F(6) = 0, so a = 6.
F(x) = ∫₆ˣ t⁷ dt
F(6) = ∫₆⁶ t⁷ dt
F(6) = 0
