Answer:
4th. as it had UNIQUE values for every x
unlike rest 3,
like 2nd has two values of 3, not a function
We will apply the Pythagoras theorem to find the measure of the unknown leg in a triangle when one leg and the hypotenuse are provided dimensions.
<h3>What is the definition of a right-angle triangle?</h3>
It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometric function.
According to Pythagoras, the sum of the squares of two sides equals the square of the longest side.

Where,
h is the hypotenuse
p is the perpendicular
b is the base
If any of the two is given the third side will be obtained using the Pythagoras theorem.
In a triangle with given measurements for one leg and the hypotenuse, we will determine the measure of the unknown leg by the Pythagoras theorem.
Hence we willl apply the pythogorous theorem for finding the unknown side.

A. Expanding the given expression, you have
balance = 75r^2 +150r +75
B. For r=0.10, the balance after 2 years is 75*1.1^2 = 90.75
C. The difference between $120 and 90.75 is $29.25. You need $29.25 more to buy the bicycle.

Answer:
Number of times she will hit the ball the next time she plays softball if she is at bat 20 times = 9 times
Step-by-step explanation:
Percentage of times Sierra hit the ball when she was at bat playing softball= 45%
So, we can find:
Number of times she will hit the ball the next time she plays softball if she is at bat 20 times =
