The height, h, in feet of a golf ball above the ground after being hit into the air is given by the equation, h = -16t 2 + 64t, where t is the number of seconds elapsed since the ball was hit. How many seconds does it take for the golf ball to hit the ground?

It will take ___seconds for the ball to hit the ground.

Answers

Answer 1

Answer:

4 seconds

Step-by-step explanation:

When the ball hits the ground the height is 0

-16t² + 64t = 0

Divide both sides by -16

t² - 4t = 0

Factor out t

t(t - 4) = 0

From the zero product rule

t = 0    and    t - 4 = 0

t = {0, 4}

The ball hits the gound after 4 seconds

Answers

Answer:

A number multiplied by its self for ex 7 x 7 = 49 square root of 49 is 7

Answer:

A square root of a number is a value that, when multiplied by itself, gives the number. 6 · 6 = 36, so a square root of 36 is 6. You are probably curious why I said a square root and not the square root. - 6 · - 6 = 36. - 6 is a square root of 36. The symbol is √ which always means the positive square root.

√1 = 1

√4 = 2

√9 = 3

√16 = 4

√25 = 5

√36 = 6

√49 = 7

√64 = 8

√81 = 9

Glenn has a garden that is shaped like a rectangle.

The perimeter of his garden is 7012 feet.
The length of the garden is 2434 feet.

What is the width of the garden?


21 ft o 11ft o 10 ½ ft o 45 ¾ ft

Answers

Answer:

Solution given:

The length of the garden[l] = 2434 feet.

breadth or width [b]=b

perimeter of his garden = 7012 feet.

2[l+b]=7012ft

2434+b=7012/2

b=3506-2434

b=1072

So the width of the garden is 1072ft.

Find the slope of the line through the given points.
(-1,1) and (3, -7)

Answers

Answer:

Slop of the line M = -2

Step-by-step explanation:

Given coordinates;

(-1 , 1) , (3 , -7)

Find:

Slop of the line

Computation:

We know that;

x1 = -1

x2 = 3

y1 = 1

y2 = -7

Slop of the line M = Δy / Δx

Slop of the line M = (y2 - y1) / (x2 - x1)

Slop of the line M = (-7 - 1) / [3 - (-1)]

Slop of the line M = (-8) / [3 + 1]

Slop of the line M = (-8) / (4)

Slop of the line M = -2

Jack is wrong because he used the distributive property wrong. On the top equation, you see 2(4k - 3). The 2 multiplies into the (), so basically you have

2 x 4k - 2 x 3

which gives you

8k - 6

Answer:

Taniyah

Step-by-step explanation:

Taniyah is correct because you need to:

diistribute : 8k - 6 - 6k = 14

combine like terms : 2k - 6 = 14

add 6 to both sides : 2k - 6 + 6 = 14 + 6

simplify : 2k = 20

divide both sides by the same factor : 2k/2 = 20/2

simplify : k = 10

During a storm one and five hundredths inches of rain fell near Marie's house which shows the amount of rain in standard form?

Answers

Answer:

1.05 * 10⁰

Step-by-step explanation:

Standard form is a way of representing either very large or very small numbers easily.

If a number is to be written in standard form, you have to first write down the number between 1 and 10, then you write × 10(to the power of a number).

Given that the amount of rain that fell near Marie's house is one and five hundredths inches of rain.

Amount of rain = one and five hundredths inches of rain = 1 + 5/100 = 1 + 0.05 = 1.05

Amount of rain in standard form = 1.05 * 10⁰

What is matrix multiplication?

Matrix multiplication is a binary operation whose output is also a matrix when two matrices are multiplied.

To multiply one matrix with another, we need to check first, if the number of columns of the first matrix is equal to the number of rows of the second matrix. Now multiply each element of the column of the first matrix with each element of rows of the second matrix and add them all.

Given

Matrix equations

[tex]\left[\begin{array}{ccc}2&4\\1&2\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}6\\3\end{array}\right][/tex]

L.H.S:

Using Matrix multiplication

[tex]\left[\begin{array}{ccc}2&4\\1&2\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}2x+4y\\x+2y\end{array}\right][/tex]

R.H.S:

[tex]\left[\begin{array}{ccc}6\\3\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc}2x+4y\\x+2y\end{array}\right]=\left[\begin{array}{ccc}6\\3\end{array}\right][/tex]

Writing equation from above matrix

2x + 4y = 6

x + 2y = 3

or

2x + 4y = 6

2x + 4y = 6

Because there are two unknown number, but the two equations are consistent.

So, the system of equations has infinite solutions.

Option D is correct.

Solve by elimination.

-2(p + 3s) = 53

Equation 2 turns into -2p - 6s = -106

2p + 4s = 76
-2p - 6s = -106

Combine alike terms

-2s = -30
s = 15


Use one of the original equation and plug “s” in.
