X^2 + 3x - 10 = 0

2x + 3x - 10 = 0

2x + 3x = 5x

5x -10 = 0

+10 +10

5x = 10

5x/5 = 10/5

X = 2


Checking: 2^2 + 3(2) - 10 = 0

4 + 3(2) - 10 = 0

4 + 6 - 10 = 0

10 - 10 = 0

0 = 0

Whitney kicks a football off the ground. The height, h , in feet, of the football above the ground after t seconds is given by h
malfutka [58]

Answer:

<em>after 4seconds</em>

Step-by-step explanation:

Given the height, h , in feet, of the football above the ground after t seconds expressed by h ( t ) = − 8 t^2 + 32 t, the height of the ball on the ground is 0feet.

Substitute h(t) = 0 into the expression and calculate t;

h ( t ) = − 8 t^2 + 32 t

0 = − 8 t^2 + 32 t

8t² = 32t

8t = 32

Divide both sides by 8

8t/8 = 32/8

<em>t = 4s</em>

<em>Hence the football hits the ground after 4seconds</em>

The value of y varies directly with x. If x = 8, then y = 96. What is the value of x when y = 168?
patriot [66]

Answer:

  • x = 14

Step-by-step explanation:

<u>Direct variation equation:</u>

  • y = kx, where k is constant of variation

<u>Given:</u>

  • 96 = 8k
  • k = 96/8
  • k = 12

<u>The equation is:</u>

  • y = 12x

<u>Find the value of x when y = 168:</u>

  • 168 = 12x
  • x = 168/12
  • x = 14

A = πab/4 solve for b
Studentka2010 [4]

Answer:

4A/ (πa)  = b

Step-by-step explanation:

A = πab/4

Multiply each side by 4

4A = 4πab/4

4A = πab

Divide each side by πa

4A/(πa)  = πab/ πa

4A/ (πa)  = b
