Need helping showing step by step answer to solve for f.

Alex73 [517]

You cannot "solve for f" here. However, you can find the zeros/roots of f. Set f = to 0. Then, one by one, set each of the factors = to 0 and solve for x:

x+1=0 results in x=-1; x-5=0 results in x=5, and so on.

Thus, the solutions of f(x)=0 are {-1, 5, -3, 4, 8}

Sphere A has a radius of 24 centimeters, and sphere B has a diameter of 42 centimeters. The radius of sphere A is multiplied by

sashaice [31]

Ok, so we know that the radius of Sphere A is 24 cm, and we know that the diameter of Sphere B is 42 cm. To find the radius of Sphere B, all we need to do is divide the diameter by two. The radius of Sphere B is 21 cm. 24 times what factor is 21? Well, $24* \frac{21}{24}$ is equal to 21. All we need to do now is simplify it. Divide the numerator and denominator by 3, and we get $\frac{7}{8}$
