Craig is constructing weights of different sizes to use in his home gym. One such weight is a solid steel sphere with a radius o
bearhunter [10]

The approximate mass of the spherical weight is 51 pounds

To answer the question, we need to know what the mass of the sphere is

<h3>Mass of the sphere</h3>

The mass of the sphere m = ρV where

  • ρ = density of steel = 0.284 lb/in³ and
  • V = volume of sphere = 4πr³/3 where
  • r = radius of sphere = 3.5 in

So, m = ρV

= ρ4πr³/3

Substituting the values of the variables into the equation, we have

m = ρ4πr³/3

= 0.284 lb/in³ × 4π(3.5 in)³/3

= 0.284 lb/in³ × 4π × 42.875 in³/3

= 48.706π lb/3

= 153.014 lb/3

= 51 lb

The approximate mass of the spherical weight is 51 pounds

The graph of which function will have a maximum and a y-intercept of 4?
stiv31 [10]

Answer:

<h2>f(x) = -x² + 2x + 4</h2>

Step-by-step explanation:

We have quadratic functions f(x) = ax² + bx + c.

c - y-intercept

If a > 0, then a parabola opens up and has a minimum in a vertex.

If a < 0, then a parabola opens down and has a maximum in a vertex.

The function has maximum and y-intercept of 4:

a < 0 and c = 4
