Answer:

f(-3) = -17

f(0) = -2

f(1) = 3

Step-by-step explanation:

f(-3) = 5 + 5(-3) - 7

5 -15 - 7

-10 - 7

=-17

f(0) = 5 + 5(0) -7

5 + 0 - 7

5 - 7

=-2

f(1) = 5 + 5(1) - 7

5 + 5 - 7

10 - 7

Answer:

  a) 272 feet

  b) 3 seconds

  c) 7.123 seconds

Step-by-step explanation:

A graphing calculator provides an easy way to answer questions about the parameters of a quadratic function. Here the graph shows ...

a) the maximum height is 272 feet

b) it takes 3 seconds to get there

c) the rocket crashes after about 7.123 seconds

__

You can solve this algebraically by rewriting the equation in vertex form.

  h(t) = -16t² +96t +128 . . . . . . given

  h(t) = -16(t² -6t) +128 . . . . . . . factor out leading coefficient

  h(t) = -16(t² -6t +9) +128 -(-16)(9) . . . . complete the square

  h(t) = -16(t -3)² +272 . . . . . . write in vertex form

The vertex of the height function is (3, 272) meaning the rocket reaches a maximum height of 272 feet after 3 seconds.

__

The zero of the function can be found to be ...

  0 = -16(t -3)² +272

  0 = (t -3)² -17 . . . . . . divide by -16

  t -3 = ±√17 . . . . . . add 17, take the square root

  t = 3 +√17 ≈ 7.123106 . . . . . positive time value for h(t) = 0

It takes about 7.12 seconds for the rocket to crash.

Answer:

a joke and a cartoon together cost $80

c=$15   j=$65

Step-by-step explanation:

j=joke

c=cartoon

8j +6c = 610

6j+8c = 510

    Multiply the first by 8

    Multiply the second by -6

64j +48c = 4880

-36j -48c = -3060

      ADD both (c will cancel)

28j = 1820

j= 65

       PLUG j

8(65) + 6c = 610

520+6c = 610

6c= 90

 c = 15

       j + c   = 65+15 = 80

Answer:

41

Step-by-step explanation:

For this, you have to make two equations;

One that calculates the amount of coins

and one that calculates the amount of R

I'm going to set

R2 = x

R5 = y

To make this a bit easier to look at

So to do the number of coins, you want to do this:

x + y = 114

This is saying that the total amount of R2 coins plus the total amount of R5 coins will add up to 114

Then, you want to calculate the worth of them.

2(x) + 5(y) = 351

This is saying that for ever R2 coin there is, it will increase the total by 2, and every R5, it will increase the total by 5. When you add these together, it will come out to 351.

Then you have to solve the system of equations:

x + y = 114

2x + 5y = 351

-2 * (x + y = 114)

2x + 5y = 351

-2x + -2y = -228

2x + 5y = 351

3y = 123

y = 41

Since y is the amount of R5 coins, we know we have 41 R5 coins.

So the answer is

41

Answer:

6/9 or 1/3

Step-by-step explanation:

There is a total of 9 marbles of both colors in the bag.
(3 red marbles + 6 blue marble = 9 marbles)

This means the denominator of your probability will be 9. There are 6 blue marbles in the bag so, in conclusion, the probability that you will take a blue marble out of the bag is 6/9. Also, 6/9 when simplified, is 1/3.

Answer: C. [tex]\pi[/tex]

=======================================================

Explanation:

The x intercept always occurs when y = 0.

Use the unit circle to determine that [tex]\cos(\theta) = 0[/tex] when [tex]\theta = \frac{\pi}{2} \text{ and } \theta = \frac{3\pi}{2}[/tex]

So if [tex]x = \pi[/tex], then we have

[tex]y = \cos\left(\frac{1}{2}x\right)\\\\y = \cos\left(\frac{x}{2}\right)\\\\y = \cos\left(\frac{\pi}{2}\right)\\\\y = 0\\\\[/tex]

which shows us that [tex](\pi, 0)[/tex] is the location of one of the infinitely many x intercepts for this function.

Using the median concept, it is found that the third quartile is of is of $1,052.

The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.

In this problem, the ordered data-set is:

$379, $498, $619, $777, $895, $1,052, $1,256.

Hence, the median of $777 divides the data-set into two halfs:

Hence, the third quartile, which is the median of the second half, is of $1,052.

Answer:

x = 3

Step-by-step explanation:

These angles are actually equal to each other

This is because when two lines intersect, the two opposite angles are the same.

Since they are the same, you can set them equal to each other

Like so:

6x - 7 = 4x - 1

Then solve:

6x - 7 = 4x - 1

6x = 4x +6

2x = 6

x = 3

The maximum number of full cups of water that can be placed into the container without the water overflowing is 47 cups

Volume of the container = 10 * 15 * 20 = 3000 in³

The volume of the cylinder is:

Volume of cylinder = π * radius² * height = π * 2² * 5 = 62.83 in³

Number of cups that can be placed in container = 3000 in³ / 62.83 in³ = 47.74

Since it given that a bag of tiles contains:

6 green

4 yellow

5 blue

To Find:

If one tile is pulled at random what is the probability of NOT choosing a green tile.

Solve:

knowing that there are a total of 15 tiles {6+5+4=15}

And there is 6 green tiles

Thus, 15 - 6 = 9

Hence, the probability of Not Choosing a green tiles before simplest form is 9/15

GCD - 3

Divide both the numerator and denominator by the GCD

9 ÷ 3/15 ÷ 3

Reduced fraction = 3/5

Therefore, the probability of Not choosing a green tiles is 3/5
