Find two consecutive odd integers such that

Goryan [66]

Answer:

9 and 11

Step-by-step explanation:

let the consecutive odd integers be n and n + 2 , then

4n = 5(n + 2) - 19 , that is

4n = 5n + 10 - 19 ( subtract 5n from both sides )

- n = - 9 ( multiply both sides by - 1 )

n = 9 and n + 2 = 9 + 2 = 11

The 2 integers are 9 and 11

18. A soccer ball is kicked upward from a height of 1.5 feet with an initial vertical velocity of 35 feet per second. Its

NemiM [27]

Answer:

Part a) $-16t^{2}+35t+1.5=0$

Part b)

$a=-16\\b=35\\c=1.5$

Part c) The soccer ball will take 2.23 seconds to reach the ground

Step-by-step explanation:

we have

$h(t)=-16t^{2}+35t+1.5$

where

t is the time the ball has been in the air, in seconds

h(t) is the height, in feet, of the soccer ball

Part a) Write an equation that could be used to determine the time the ball traveled before it hit the ground

we know that

When the ball hit the ground, the value of h(t) is equal to zero

For h(t)=0

$-16t^{2}+35t+1.5=0$

This equation can be used to determine the time the ball traveled before it hit the ground

Part b) Determine the values of a, b, and c

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$-16t^{2}+35t+1.5=0$

$a=-16\\b=35\\c=1.5$

Part c) How long will it take for the soccer ball to reach the ground after it was kicked?

Solve the quadratic equation by the formula

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

we have

$a=-16\\b=35\\c=1.5$

substitute the values

$x=\frac{-35(+/-)\sqrt{35^{2}-4(-16)(1.5)}} {2(-16)}$

$x=\frac{-35(+/-)\sqrt{1,321}} {-32}$

$x_1=\frac{-35(+)\sqrt{1,321}} {-32}=-0.04$ ---> cannot be a solution (is negative)

$x_2=\frac{-35(-)\sqrt{1,321}} {-32}=2.23$

therefore

The soccer ball will take 2.23 seconds to reach the ground
