What is the length of the dotted line in the diagram below? Leave your answer in simplest radical form.
5
10

The top is a triangle with sides 7 and 5.4 Use the Pythagorean theorem to find the 3rd length.

3rd sides = sqt(7^2 + 5^2( = sqrt(49+25) = sqrt(74)

This side is the base of the lower rectangle.

The dotted line is the hypotenuse of a right triangle.

Use the Pythagorean theorem to solve.

sqrt(10^2 + sqrt(74)^2) = sqrt(174)

The dotted line = sqrt(174)

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
