Answer:

24.7 feet

Step-by-step explanation:

This is a Pythagorean theorem question

The ladder is the hypotenuse or c

the distance from the wall is a leg or a

and the wall is the other leg or b

a² + b² = c²

a² + 17² = 30²

a²  + 289 = 900

        -289    -289

          b² = 611

         √        √

          b = √611

           b = 24.7 feet

Complete the point-slope equation of the line through ( − 5 , 4 ) (−5,4)left parenthesis, minus, 5, comma, 4, right parenthesis
Tanzania [10]

The point slope form of equation through given points is:

y-6=\frac{1}{3}(x-1)

Step-by-step explanation:

Given points are:

(x1,y1) = (-5,4)

(x2,y2) = ((1,6)

First of all we have to find the slope of line

So,

m=\frac{y_2-y_1}{x_2-x_1}\\=\frac{6-4}{1+5}\\=\frac{2}{6}\\=\frac{1}{3}

Point-slope form is given by:

y-y_1=m(x-x_1)

Putting m=1/3

y-y_1=\frac{1}{3}(x-x_1)

Putting (1,6) in the equation

y-6=\frac{1}{3}(x-1)

The point slope form of equation through given points is:

y-6=\frac{1}{3}(x-1)

C(x) = -5x^2+x<br> Find c(4)
Alchen [17]

Answer:

c(4) = -76

Step-by-step explanation:

c(x) x=4 so plug 4 in for x

-5(4)² + (4)

Do parentheses first so... 4² = 16

-5(16) + 4

-5(16) = -80

-80+4 = -76

c(4) = -76
