First draw sloping up (steep because he’s running)to the right until you hit 20 on the y axis. Next draw down and to the right for 5 yards until 15 on y axis. Next is a flat horizontal line for 3 seconds on x axis. Finally a shallow slope line down (because he is walking) and right until you hit the x axis.

AC is tangent to circle O at A. The Diagram is not to scale.

statuscvo [17]

Answer:

B. 64°

Step-by-step explanation:

Given:

mBY = 52°

Inscribed angle measure is half the intercepted arc:

m∠BAY = 1/2(52°) = 26°

The angle between the diameter and tangent is right angle:

m∠BAC = 90°

According to angle addition postulate:

m∠YAC = m∠BAC - m∠BAY
m∠YAC = 90° - 26° = 64°

Correct choice is B

I wanted to know what 22/7 • 1/4 and then when you multiply it what will the answer be please help me gotta turn this in tomorro

Answer:11/14

Step-by-step explanation:

Let's multiply the numerators first. 22 x 1 is 22, so your numerator is 22.

The denominator: 7 x 4= 28, your denominator is 28.

Your answer would be 22/28.

However, we can simplify this.

22 and 28 are both divisible by 2.

22/2=11

28/2=14

Your final answer is 11/14

How can you restrict the domain of the function f(x)=|x+4|-2 so the range of the inverse function f^-1(x),is [-4, )

wariber [46]

The range of the inverse has to match the domain of the original function. We want to have $f^{-1}(x)$ map to $[-4,\infty)$ , so we restrict the domain of $f(x)$ to this interval.
