Answer:

106°

Step-by-step explanation:

The angle CAB is an inscribed angle of the arc mBC, so we have that:

mBC = 2*CAB

So we have that mBC = 2*37 = 74°

The segment AC is a diameter of the circle, so mAC = 180°

The ? angle is the arc mAB, which is the difference of mAC and mBC, so:

mAB = mAC - mBC = 180 - 74 = 106°

So the ? angle is 106°.

Daphne has 3 days to drive 932.4 miles . she wants to have completed about 75% of the drive by the start of day three.which of t

nekit [7.7K]

So, 932.4miles (.75)=699.3miles are the miles that she wants to drive by the start of three days. so each day is 25% because of 75%/3=25%
In two days it will be 50% so, .50(932.4miles)=466.2 miles is the answer.

If dy/dx = X2 + 4, What is the value of y?

uranmaximum [27]

Antideritiive
antideritive of $x^n$ is $\frac{x^{n+1}}{n+1}$
antiderititve of a constant is that constant times x
so

antideritive of $x^2$ is $\frac{x^{2+1}}{2+1}=\frac{x^{3}}{3}$
andtideritivee of 4 is 4x

total is
$y= \frac{x^3}{3}+4x+C$
