First you simplify t/2.5=-5.2
Which is 0.4t=-5.2
Then we divide both sides by 0.4 which you get t=-13 as your answer so it's D

Given that:

Miles traveled the fastball in 2 seconds = 60.5 ft

So, the ball traveled in one second

$\begin{gathered} =\frac{\text{Miles traveled in 2 seconds}}{2} \\ =\frac{60.5}{2} \\ =30.25 \end{gathered}$

The ball travels 30.25 miles per second.

Black_prince [1.1K]

Answer: Polynomials are algebraic expressions that contain more than two terms. AN example would be: f(x) = x^3 + x^2 + x +1. This equation contains three terms, with the 3rd degree as its highest term. It also means that the graph passed three x-intercepts. This depends in the highest degree. So, the first thing you do is plot the intercepts because for sure, the graph will pass there.

Answer:

Standard Form Equivalent Form Extreme Values

y=x^2-6x+17 (x-3)^2+8 (3,8)

y=x^2+8x+21 (x+4)^2+5 (-4,5)

y=x^2-16x+60 (x-8)^2-4 (8,-4)

Step-by-step explanation:

1) Standard form:

y=x^2-6x+17

Equivalent Form:

Can be found using completing the square method.

$y=x^2-6x+17\\y=x^2-2(x)(3)+(3)^2-(3)^2+17\\y=(x-3)^2-9+17\\y=(x-3)^2+8$

So, Equivalent form is: (x-3)^2+8

Extreme value:

Extreme values are basically the minimum and maximum value of the function.

Minimum Value will be found by finding derivative of the function:

The derivate is: 2x-6

Now, put the derivate equal to zero: 2x-6 = 0

$2x=6\\x=6/3 \\x=3$

Maximum value can be found by putting minimum value in the given function:

Put x = 3 and solve:

$(3)^2-6(3)+17\\9-18+17\\9-1\\=8\\$

So, the extreme values is: (3,8)

2) Standard form:

y=x^2+8x+21

Equivalent Form:

Can be found using completing the square method.

$y=x^2+8x+21\\y=x^2+2(x)(4)+(4)^2-(4)^2+21\\y=(x+4)^2-16+21\\y=(x+4)^2+5$

So, Equivalent form is: (x+4)^2+5

Extreme value:

Extreme values are basically the minimum and maximum value of the function.

Minimum Value will be found by finding derivative of the function:

The derivate of x^2+8x+21 is: 2x+8

Now, put the derivate equal to zero:

$2x+8 = 0\\2x=-8\\x=-8/2 \\x=-4$

So, minimum value is: -4

Maximum value can be found by putting minimum value in the given function:

Put x = -4 and solve:

$x^2+8x+21\\=(-4)^2+8(-4)+21\\=16-32+21\\=5$

So, Maximum value is: 5

So, the extreme values is: (-4,5)

3) Standard form:

y=x^2-16x+60

Equivalent Form:

Can be found using completing the square method.

$y=x^2-16x+60\\y=x^2-2(x)(8)+(8)^2-(8)^2+60\\y=(x-8)^2-64+60\\y=(x-8)^2-4$

So, Equivalent form is: (x-8)^2-4

Extreme value:

Extreme values are basically the minimum and maximum value of the function.

Minimum Value will be found by finding derivative of the function:

The derivate of x^2-16x+60 is: 2x-16

Now, put the derivate equal to zero:

$2x-16 = 0\\2x=16\\x=16/2 \\x=8$

So, minimum value is: 8

Maximum value can be found by putting minimum value in the given function:

Put x = 8 and solve:

$x^2-16x+60\\=(8)^2-16(8)+60\\=64-128+60\\=-4$

So, Maximum value is: -4

So, the extreme values is: (8,-4)
