A ball thrown into the air is modeled by the
equation
h(t) = -t2 + 4t + 5. Where h represents
the height of the ball and t represents
time.


What is the starting height of the ball?
What is the time the ball reaches its
maximum height?
What is the maximum height?
When does the ball hit the ground?
How high is the ball 1 second into
flight?

Answers

Answer 1

Answer:

Below in bold.

Step-by-step explanation:

Starting height is when t = 0

It is 5 units.

To find the maximum height we convert the equation to vertex form:

h = -t^2 + 4t + 5

h = -(t^2 - 4t - 5)

=  - [(t - 2)^2 - 9]

= -(t - 2)^2 + 9

From this we see that the ball reaches max height after 2.

Maximum height = -2^2 +  4(2) + 5

= 9 units.

Ball reaches the ground after 2*2 = 4 .

7 – 2y > 3y + 13; y = -1

Answers

Given:

[tex]7-2y>3y+13[/tex]

To find:

The whether the value [tex]y=-1[/tex] is a solution of the given inequality or not.

Solution:

We have,

[tex]7-2y>3y+13[/tex]

It can be rewritten as

[tex]-2y-3y>13-7[/tex]

[tex]-5y>6[/tex]

Divide both sides by -5 and change the inequality sign.

[tex]y<\dfrac{6}{-5}[/tex]

[tex]y<-1.2[/tex]

All the value of y less -1.2 are the solutions of the given inequality but -1 is greater than -1.2.

[tex]-1>-1.2[/tex]

Therefore, [tex]y=-1[/tex] is not a solution of the given inequality.

Donna borrowed $10, 500 at a simple interest rate of 4% for 3 years to buy her new car. How much interest would Donna pay and how much is the car altogether?

Answers

Question:-

Donna borrowed $10,500 at a simple interest rate of 4% for 3 years to buy her new car. How much interest would Donna pay and how much is the car altogether ?

Answer:-

Given:-

[tex] \bullet [/tex] Principal (P) = $10,500

[tex] \bullet [/tex] Rate of interest (r) = 4%

[tex] \bullet [/tex] Time (t) = 3 years

To Find:-

Interest of Donna and amount of car altogether.

Solution:-

We know,

[tex] { \boxed{\rm \red {I \: = \frac{Prt}{100}}}} [/tex]

[tex] \therefore [/tex] I = [tex] \frac{10,500 \: × \: 4 \: × \: 3}{100} [/tex]

I = [tex] \frac{126,000}{100} [/tex]

I = $1260

Now,

Amount of the car = $ (10,500 + 1260)

= $ 11,760

$1260 interest would Donna pay and $11,760 is the car altogether. [Answer]

Step-by-step explanation:

We know that Interest = Principal×Rate×Time/100

So,

10,500×4×3/100

= 10,500×3/25 (by cancelling 100 by 4)

=31500/25

= 1260

Therefore,
