a projectile is thrown upwards from an initial height of 1584 feet so that it's distance above the ground after t seconds is modeled by the given function.
h(t)=-16t^2+480t+1584.

what is the maximum height it will reach?

Answers

Answer 1

Answer:

5184 ft

Step-by-step explanation:

Given

A quadratic function

h(t)= -16t^2+480t+1584.

Its maximum is its vertex

Vertex formula for ax^2 + bx + c is

x = -b/2a

Applying this to our function

t = -480/2(-16) = 15

Maximum height is reached after 15 seconds and is

h(15) = -16*15^2 + 480*15 + 1584 = 5184 ft

The perimeter of PRST is 10 more than 5(RS). If PR=26, find RS.

Answers

Answer:

RS = 14

Step-by-step explanation:

Perimeter = 26 + 26 + PT + RS

We know that PT and RS are equal to each other so I changed the equation to 26 + 26 + x + x = 10 + 5x and then I got x by itself and the integer on one side 42 = 3x, so 14 = x

The value of RS will be 14 for the given parallelogram.

What is a parallelogram?

A basic quadrilateral with two sets of parallel sides is known as a parallelogram.

A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size.

There are 4 types of parallelograms, including 3 special types. The four types are parallelograms, squares, rectangles, and rhombuses.

Given the parallelogram where TS ║ PR and both are equal

Line TP ║ SR so it means TP = SR

Let's say

TP = SR = x

Now,

The perimeter of a parallelogram is 10 more than 5(RS)

So,

PT + TS + SR + RP = 5(RS) + 10

Now since TP = RS = x

So,

x + TS + x + RP = 5x + 10

5x - 2x = TS + RP - 10

x = (TS + RP - 10)/3

Now,

TS = RP = 26

So,

x = (26 + 26 - 10 )/3

x = 42/3

x = 14

Hence "The value of RS will be 14 for the given parallelogram".

James decides to invest money in Wal-Mart. As a shareholder, he has the advantage of

(select all that apply)

A. limited liability

B. limited life

C. unlimited liability

D. double taxation

E. ease of start up

Answers

Answer:

A. limited liability

Step-by-step explanation:

Because James has become a shareholder by investing in Walmart, he has the advantage of limited liability. This basically means that he shares in both the gains and the losses of Walmart's business decisions but only up to the amount that he has invested into it. Meaning that if James invested a total of $2000 and Walmart goes under, then he will lose all $2000 but not more than that.

Answer:

A. 2(3x+15) + 2(6x+6) = 96

B. x=3

Step-by-step explanation:

A. The original equation would be (3x+15) + (6x+6) + (3x+15) + (6x+6)

Step 1: you can simplify this to 2(3x+15) + 2(6x+6) because there are two of each of each equation.

Step 2: The question says that the perimeter equals 92, and because it is an equation, you should put =92 at the end.

B. Step 1: You should solve out each question separately, so 2(3x+15) = 6x + 30. This is because 2 × 3x = 6x and 2 × 15 = 30.

2(6x+6) = 12x + 12 because 2 × 6x = 12x and 2 × 6 = 12.

Step 2: Add the two: 6x + 30 + 12x + 12

6x + 12x = 18x and 30 + 12 = 42.

Step 3: Now we have a new equation: 18x + 42 = 96

Solve this like a normal equation. (Subtract 42 from both sides to get 18x = 54. Then divide by 18 on each side. This will give you x=3)

If LP = 15 and PR = 9, find LR. Explain. LR = 24 because 15 + 9 = 24 according to the addition property of equality. LR = 6 because LR + LP = PR according to the Segment Addition Postulate, and 6 + 9 = 15 using substitution. LR = 24 because LP + PR = LR according to the Segment Addition Postulate, and 15 + 9 = 24 using substitution. LR = 6 because 15 − 9 = 6 according to the subtraction property of equality.

Answers

Step-by-step explanation:

Given,

LP = 15, PR = 9

Point P lies on the line segment PR. It would mean that,

LP + PR = LR

⇒LR = 15 + 9

⇒ LR = 24

Hence, "LR = 24 because LP + PR = LR according to the Segment Addition Postulate, and 15 + 9 = 24 using substitution" is the correct option.

Automated vehicles, the NHTSA writes, could reduce the frequency of crashes by eliminating some human error on the roads.
