A soccer ball is kicked from the ground with an initial upward velocity of 90 feet per second. The equation h=-16t^2+90t gives the height h of the ball after t seconds.

a. Find the maximum height of the ball.

b. How many seconds will it take for the ball to reach the ground?

Answers

The ball reaches a height of 126.58 ft after 2.8125 seconds

Step-by-step explanation:

The maximum height of a parabola can always be found by looking for the vertex. You can find the x value (or in this case the t value) of a vertex by using -b/2a in which a is the coefficient of x^2 and b is the coefficient of x.

-b/2a

-(90)/2(-16)

-90/-32

2.8125 seconds

Now to find the height, we input that value in for t

h = -16t^2 + 90t

h = -16(2.8125)^2 + 90(2.8125)

126.58 feet

If you bought a stock last year for a price of $103, and it has risen 7% since then, how
much is the stock worth now, to the nearest cent?

Answers

Answer:

the stock is worth $110.21

Step-by-step explanation:

The first thing you want to do is multiply 0.07 and 103, to find out what 7% of 103 is. When you multiply those two numbers you are going to get 7.21. You are then going to add 103 and 7.21 to find out how much it would be worth now.

Answer:

$110.21

Step-by-step explanation:

well 7% of 103 is 7.21  so if you add that to 103 it = 110.21

The height of the right circular cylinder shown below is 10 feet and its base has a radius of 4 feet. A. B. C. D.

Answers

Answer:

502.4ft^3

Step-by-step explanation:

Given data

Height= 10ft

radius= 4 ft

Hence the volume for the cylinder can be gotten as

v= πr^2h

v= 3.14*4^2*10

v=3.14*16*10

v=502.4ft^3

Therefore the volume of the cylinder is 502.4ft^3

Step-by-step explanation:

IM NOT SMART SUBSTITUTION METHOD AGAIN

Answers

Answer:

x = 6

y = -3

Step-by-step explanation:

15x + 31y = -3

we are given that x =( - y + 3 )

so in the equation 15x + 31y = -3 we substitute "x" for ( -y + 3 ) and we solve for y

so 15 ( -y + 3 ) + 31y = -3

now we use basic algebra to solve for y

step 1 distribute the 15

15 * -y = -15y

15 * 3 = 45

now we have 45 - 15y + 31y = -3

step 2 combine like terms

-15 + 31y = 16y

now we have 45 + 16y = -3

step 3 subtract 45 from each side  

-3 - 45 = -48

45 - 45 cancels out

now we have 16y = -48

step 4 divide each side by 16

16y/16=y

-48/16=-3

we're left with y = -3

Now to find x we substitute -3 for y in x  = -y + 3

* substitute *

x = - ( -3) + 3

the two negative signs cancel out and we get x = 3 + 3

3 + 3 = 6

we're left with x = 6

Answer:

Select the three ratios that represent the numbers of blue marbles to red marbles, there are 6 blue marbles and 9 red marbles

Answers

Answer:

6:9 or (2:3)

Step-by-step explanation:

A ratio is a term that gives comparison of values. It helps to determine

how much of a particular thing that is compare to other thing.

Given:

numbers of blue marbles= 6

numbers of red marbles= 9

Hence, ratios that represent the numbers of blue marbles to red = 6:9

We can reduce it using factor of 3, hence the ratio becomes(2:3)

These are the cost and revenue functions for a line of 24-pound bags of dog food sold by a large distributor:






R(x) = -31.72x2 + 2,030x

C(x) = -126.96x + 26,391


The maximum profit of $ Blank

can be made when the selling price of the dog food is set to $ Blank

per bag.

there are two answers

Answers

Answer:

$10,277.32

Step-by-step explanation:

Given the revenue and cost function

R(x) = -31.72x^2 + 2,030x

C(x) = -126.96x + 26,391

The profit function is expressed as;

P(x) = R(x) - C(x)

P(x) = -31.72x^2 + 2,030x-(-126.96x + 26,391)

P(x) = -31.72x^2 + 2,030x+126.96x - 26,391

P(x) = -31.72x^2 + 2,030x+126.96x - 26,391

P(x) = -31.72x^2 + 2,156.96x - 26,391

To have maximum profit, d

The maximum profit dP/dx = 0

dP/dx = -63.44x+2156.96

-63.44x+2156.96=0

63.44x = 2156.96

X = 2156.96/63.44

x = 34

Get the profit

P(34) = -31.72(34)² + 2,156.96(34)- 26,391

P(34) = -36668.32+73336.64-26391

P(34) = 10,277.32

Hence the maximum profit that can be made is $10,277.32
