A wire is needed to support a vertical pole 24 feet tall. The cable will be anchored to a stake 7 feet from the base of the pole. How much cable is needed?? PLS HELP

length of cable = 25ft

Step-by-step explanation:

right angle triangle with

b= 7 ft

h = 24 ft

hyp^2 = 7^2+24^2

= 625

hyp = 25 ft

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
