Can you help me?hahahahha
Answer:
The measure of the arc DAC is 240°
Step-by-step explanation:
we know that
The semi-inscribed angle is half that of the arc it comprises.
so
m∠RDC=(1/2)[arc DAC]
we have
m∠RDC=120°
substitute
120°=(1/2)[arc DAC]
240°=[arc DAC]
Rewrite
arc DAC=240°
These are the statements that accompany this question:
<span>A.The function is a linear function.
B.The function is a nonlinear function.
C.The function does not change at a constant rate.
D.The function is an increasing function.
E.The function changes at a constant rate.
An this is the assesment of each of statement:
</span>
<span>A.The function is a linear function.
TRUE: a linear function can take the forms Ax + By - C = 0, or y = mb + b
You can verify that y = 2000 - 90 x is of this type.
B.The function is a nonlinear function.
FALSE: we showed the opposite in A)
C.The function does not change at a constant rate.
FALSE: the rate of change of a linear function is constant and it is known as the slope.
D.The function is an increasing function.
FALSE: the value of y decreases as x increases, given that the slope is negative ( -90).
E.The function changes at a constant rate.
TRUE: the constant rate is the slope, i.e. - 90.

He was meant to divide by 3 when the equation was 3x=15, not multiply, so he would get the answer x=5
