Answer:

Step-by-step explanation:
The given function is

Which can be rewritten also as

We want to find the values of x for which

In order to do that, we just substitute -12 into f(x), and we solve the equation for x:

Question 23
Lateral Surface Area = πD x height
Lateral Surface Area = π (4) (6) = 75.40 in²
Question 24
Total Surface Area = 2(8.2 x 3.4) + 2(8.2 x 2) + 2(3.4 x 2)
Total Surface Area = 36.56 in²
Question 25
Total Surface Area = 2(10 x 12) + 2(12 x 4) + 2(10 x 4)
Total Surface Area = 416 in²
Answer:0.6
Step-by-step explanation:
The radian measures of the central angle of the sector is 2
Given,
In the question:
Perimeter of sector is 4 times of its radius .
To find the radian measures of the central angle of the sector is?
Now, According to the question:
We know:
The perimeter of the circumference is = 2
r
If the perimeter of a sector is 4 times its radius.
then, the arc measure of the sector is (4r-2r) → 2r
So, if 2×
radians (full circle) has a length → 2
r
X radians → 2× r (the sector)
X=2× r ×(2×
)/(2
r)
X = 2
Hence, The radian measures of the central angle of the sector is 2.
