the value of x is -3. Option B
<h3>How to determine the value</h3>
WE have the expression to be;
4^x=(1/8)^x+5
With the knowledge of indices, we have that;
2 = 2 ^1
4 = 2^2
8 = 2^3
16 = 2^4
32 = 2^5
So from this given information,
we can express the expression as;
4^x = 2^2x
1/8^x = 2^-3x
Substitute into the formula
2^2x = 2^-3x - 15
Cancel out the like terms
2x = -3x - 15
collect like terms
2x + 3x = - 15
x = -15/ 5
x = -3
Thus, the value of x is -3. Option B

Answer:
140
Step-by-step explanation:
You want the area. You do not have to take the square root. First of all you have to assume this is a right angle triangle.
c^2 = b^2 + a^2
c^2 = 200
b^2 = 60
a^2 = ?
200 = 60 + a^2
200 - 60 = a^2
a^2 = 140
Let's examine your answer choices:
A The arc length of the smaller circle is half the arc length of the larger circle.
Hmmmm that can't be right. The arc length of a 60° angle must be equal to the arc length of another 60° angle!
Hey! Would you look at that! With that knowledge you can answer the question!
The correct answer is B because the arc length of a 60° angle is equal to the arc length of another 60° angle!
So the correct answer is B! Hope that helps!
