The value of x is 1
Explanation:
The equation is
Subtracting both sides by 3, we get,
Taking log on both sides, we get,
Rewriting the equation by
Thus, we have,
Applying log rule, if , then
Thus,
Substituting in , we get,
Also, since, , then
Thus,
Hence, the value of x is 1
Answer:
A.
Step-by-step explanation:
To divide the complex number: , we rationalize with the conjugate of the denominator.
This gives us:
We apply the distributive property to get:
We simplify to get:
This implies that:
The correct answer is A.
Answer:
Area of sector = 144.4π cm²
Step-by-step explanation:
Given:
Perimeter of circle = 40π cm
Given angle = 130°
Find:
Area of sector
Computation:
Perimeter of circle = 2πr
⇒ 40π = 2πr
⇒ 40 = 2r
⇒ Radius r = 40 / 2
Radius r = 20 cm
Area of sector = [θ/360][π][r]²
⇒ Area of sector = [130/360][π][20]²
⇒ Area of sector = [0.361][π][400]
Area of sector = 144.4π cm²
i wish i could help. But it is really blurred. can you set up a better picture? thanks.
