Answer:

Okay so our number in this example is going to be 23 because it is my favorite.

So you start of by saying okay

23+0.1

and that would equal 23.1

and then you would think

23-0.1

and that would equal 22.9

and then you would do the same thing just move a place

so 23+0.001

and that would equal 23.001

and then you subtract it

so 23-0.001

and that would equal 22.999

hope this helped :)

Sloane kicked a soccer ball off the ground at a speed of 48 feet per second. The height of the ball can be represented by the fu

Marat540 [252]

If the speed of the ball after kicking is 48 feet per second then the ball will return on the ground after 3 seconds.

Given that the speed of the ball after kicking is 48 feet per second and the function that represents the height of the ball is $-16t^{2} +48t$ .

We are required to find the time that the ball took to travel before returning the ground.

We know that speed is the distance a thing covers in a particular time period.

The height of the ball after t seconds is as follows:

h(t)= $-16t^{2} +48t$

It is at ground at the instants of t.

Hence,

$-16t^{2} +48t$ =0

-16t(t-3)=0

We want value of t different of 0, hence :

t-3=0

t=3.

Hence if the speed of the ball after kicking is 48 feet per second then the ball will return on the ground after 3 seconds.

use the elemination method to solve the system of equations choose the correct ordered pair 3x+5y=48 -3x+5y=12

BlackZzzverrR [31]

Answer:

$y=6\\x=6$

Step-by-step explanation:

$3x+5y=48$

$-3x+5y=12$

sum the two equations

$10y=60\\y=6\\3x+5y=48\\3x=48-5*6\\x=6\\$
