Answer:

[tex]\huge\boxed{\text{1. } h(t) = -5(t-3)^2 + 45}[/tex]

[tex]\huge\boxed{\text{2. 3 seconds}}[/tex]

Step-by-step explanation:

If we're looking for the point at with the ball reaches its highest point, we want to find the graph's vertex. In order to get the equation into a form with the vertex in it, we need to convert the equation into vertex form. This is an equation in the form [tex]y=a(x-h)^2 + k[/tex], h being the x value of the vertex, and k being the y value of the vertex.

In order to convert our equation, [tex]-5t^2+30t[/tex] into vertex form, we can algebraically manipulate it to get it into the form we want.

Therefore, our equation with the vertex in it is [tex]-5(t-3)^2 + 45[/tex]. To find the vertex, we can examine the equation to find the values of h and k in the formula  [tex]y=a(x-h)^2 + k[/tex] (where the vertex coordinates are (h, k)).

It seems that h is 3 and k is 45. Therefore, the coordinate of the vertex is (3, 45). Since it asks for how many seconds after being hit does the ball reach its highest point, we would take the x value since x represents seconds. This is 3. Therefore, the ball reaches its highest point after 3 seconds.

Hope this helped!

Answer:

x=2.5, y=6.5

Step-by-step explanation:

Y=x+4  ,y=3x-1

x+4=3x-1

2x=5

x=2.5

y=x+4=2.5+4=6.5

In his 1961 inaugural address, John F. Kennedy declared that “the torch has been passed to a new generation of Americans.” He was referring to the fact that a 43-year-old was replacing a 70-year-old in the White House, but his words were meant to resonate as well with even younger Americans who were just...

happy new year!

Answer:

2x+2

Step-by-step explanation:

It's multiplicative distribution - when you multiply something in parenthesis by another expression, you distributively multiply the expression to the expression in the parenthesis.

-1 is the first line after 0

8 is 3rd line one the right side after 5

-11 is just first line after 10..

I hope U understand

Answer:

plot the numbers on the dots you count. if its negative, go down from zero, if its positive go to the right.

Answer:

Danielle earns $1.20 more than Mackenzie (per hour)

Step-by-step explanation:

To find out how much money per hour each person earns, you would divide the earinings by the number of hours;

Danielle: $36.80/4 = $9.20 per hour

MackKenzie: $50.40/6 = $8.40 per hour

To find out how much extra Danielle earns, you would subtract 8.40 from 9.20;

9.40 - 8.20 = $1.20

Thus, Danielle earns $1.20 more than Mackenzie per hour.

Answer:

Jamarcus is the better shooter

Step-by-step explanation:

Jamarcus is better because he needs 10 more shots to reach 25 while tyrell needs 18 More shots to make 50

Answer:

Tyrell

Step-by-step explanation

Well this is simple you take Jamarcus shots made and divide it into the total shots which is 15/25=0.6 or 60%. So Jamarcus made 60% of the shots attempted. Tyrell made 32 out of 50 shots so that will be 32/50=0.64 or 64%. Since 64%>60% Tyrell is the better shooter

Answer:

Your answer is going to be a=1

Step-by-step explanation:

First things first, we want all the letters on the left side and all the numbers on the right side. So, you have to get rid of the three. In order to get rid of the three you have to take it away, so A/5=8-3. Then it will become A/5=5. After that you want to have A all by itself so divide it by 5, A/5=5/5. Then it will become A=1. Hope this helps! :)

Answer:

Answer:

62.5

Step-by-step explanation:

slope of AB = (5-2)/(-1 - 3) = -3/4

slope of BC = (2 - -2)/(3-0) = 4/3

AB ⊥ BC  (slope -3/4 vs 4/3)

seg AB = √(-1 - 3)² + (5 - 2)² = √25 = 5

seg BC = √(3 - 0)² + (2 - -2)² = √25 = 5

seg AD = √(-1 - -13)² + (5 - -11)² = √400 = 20

Area   (BC + AD) * AB / 2 = (5 + 20) * 5 / 2 = 62.5

Also can you please help me answer my most recent question?

Given:

The equation is

[tex]5^x=55[/tex]

To find:

The value of x.

Solution:

We have,

[tex]5^x=55[/tex]

Taking log both sides, we get

[tex]\log (5^x)=\log (55)[/tex]

[tex]x\log (5)=\log (55)[/tex]        [tex][\because \log x^n=n\log x][/tex]

[tex]x=\dfrac{\log (55)}{\log (5)}[/tex]

Using the log values, we get

[tex]x=\dfrac{1.740}{0.699}[/tex]

[tex]x=2.48927[/tex]

[tex]x\approx 2.49[/tex]

Therefore, the correct option is B.
