Determine whether the forces in the pair are pulling at right angles to each other.

snow_tiger [21]

Given:
right triangle
a = 2.9
c = 4.2

Pythagorean Theorem: a² + b² = c²

missing value of b.

b² = c² - a²
b² = (4.2)² - (2.9)²
b² = 17.64 - 8.41
b² = 9.23
b = √9.23
b = 3.03 or 3.0

The value of b is 3.0

A solid right pyramid has a square base with an edge length of x cm and a height of y cm. Which expression represents the volume

solniwko [45]

Answer:

Thus, volume of pyramid = $\frac{1}{3}x^2y$ cm³

Step-by-step explanation:

Given: A solid right pyramid has a square base with an edge length of x cm and a height of y cm.

We have to choose from the given options an expression for the volume of the pyramid.

Volume of pyramid = $\frac{1}{3}\times Area\ of\ base \times height$

Since base is a square with edge length x cm.

Area of square = (side)² = x²

Thus, volume of pyramid = $\frac{1}{3}x^2y$ cm³
