Find the slope and the y-intercept of the line Y=-5/4x+8

insens350 [35]

Explanation: This is a linear equation because it's written in slope-intercept form or y = mx + b where the multiplier or the coefficient of the x-term represents the slope of the line and the b represents the constant term.

So the slope will be the coefficient of the x-term which means the number that is in front of the x which in this case is -5/4.

The y-intercept is the constant term which is +8

A bowl is in the shape of a hemisphere (half a sphere) with a diameter of 8 inches. Find the volume of the bowl. Use 3.14 for pi

gayaneshka [121]

Answer: 267.947 (or 267.95) inches^3

Step-by-step explanation:

The formula for the volume of a sphere is $\frac{4}{3}\pi r^{3}$ .

To find your radius (r), divide the diameter of 8 inches by 2. The radius is 4 inches.

Plug in your numbers to the volume equation to get $\frac{4}{3} (3.14)(4^3)$ . The first step is to cube 4 (4*4*4) to get 64. Now your equation is $\frac{4}{3}(3.14)(64)$ .
