The measure of angle ACB for circle centered at point O is 21°
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
∠AOB = 2 * ∠ACB (angle at center is twice the angle at circumference)
42 = 2 * ∠ACB
∠ACB = 21°

Answer:
A: product of powers
B: quotient of powers
E: negative exponent
Step-by-step explanation:
Let's evaluate to see which several rules we would be applying in each step
(power of a power)
(quotient of powers)
(negative exponent)
Thus, the rules of exponents we have applied to far are:
A: product of powers
B: quotient of powers
E: negative exponent
An independent variable is what one controls and changes. A dependent variable is not controlled and is determined by the independent variable.
The independent variable is the hours doing landscaping work.
The dependent variable is the total earnings.
Hope this helps!!
Simplification would be:
y=(x+2)+4
=x+2+4
=x+6
Answer:
C.
Step-by-step explanation:
The sqrt of -16 is the same as the sqrt of 16 * the sqrt of -1. The sqrt of 16 is 4, and the sqrt of -1 is i. Multiply the two to get 4i.
