A soccer field is a rectangle 90 meters wide and 120 meters long. The coach asks players to run from one corner to the other cor
Arturiano [62]

Answer:

150

Step-by-step explanation:

If you draw a diagram, this will be a rectangle and the line across cuts it into a right triangle, with a base of 120 and a height of 90. The need to know the length of the hypotenuse of the triangle, so we can use the pythagorean theorem.

90^2 + 120^2 = c^2

c=150

A right triangle has a hypotenuse of 70 feet and a leg of 35 feet. What is the length of the other leg?
Hunter-Best [27]
We are given the two sides of the right triangle therefore we can use the pythagorean theorem to solve for the third side. This theorem states that, in a right triangle the square of the hypotenuse is equal to the sum of the square of each leg.

c² = a² + b²
70² = 35² + b²
b = √70² - 35²
b = 60.62 feet

MariettaO [177]

Answer:

(B)2

Step-by-step explanation:

Given the ordered pairs

(2,    4)\\(-3,     0)\\(-1,      -1)\\(4,       3).

The first value in the pair represents the x-value and the second value represents f(x).

In the pair (2,4)

x=2

f(x)=4

Therefore: f(2)=4.

The value of x when f(x)=4 is 2.
