find the code word tyyy

Answer:

t = 4 seconds

Step-by-step explanation:

The height of the projectile after it is launched is given by the function :

[tex]h(t)=-16t^2+32t+128[/tex]

t is time in seconds

We need to find after how many seconds will the projectile land back on the ground. When it land, h(t)=0

So,

[tex]-16t^2+32t+128=0[/tex]

The above is a quadratic equation. It can be solved by the formula as follows :

[tex]t=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]

Here, a = -16, b = 32 and c = 128

[tex]t=\dfrac{-32\pm \sqrt{(32)^2-4\times (-16)(128)} }{2\times (-16)}\\\\t=\dfrac{-32+ \sqrt{(32)^2-4\times (-16)(128)} }{2\times (-16)}, \dfrac{-32\- \sqrt{(32)^2-4\times (-16)(128)} }{2\times (-16)}\\\\t=-2\ s\ \text{and}\ 4\ s[/tex]

Neglecting negative value, the projectile will land after 4 seconds.

Step-by-step explanation:

The contrapositive of this statement would be: "If x does not equal -4, then 5x + 7 will not equal to -13."

The contrapositive is defined as the inverse and converse of a conditional statement.

X is equal to 4 we know this is because the sign in between the number means greater than or equal to so 3 x 4 equals 12 which makes the equation on right true and on the left x.

So, the contrapositive of this statement would be:

"If x does not equal -4, then 5x + 7 will not equal to -13."

Answer:

Jack needs to run at a speed of 1/12 mph

Step-by-step explanation:

Mathematically;

speed = distance/ time

Distance = speed * time

10 minutes = 10/60 h = 1/6 hours

The distance to the school will be

Distance = 3 * 1/6 = 1/2 = 0.5 miles

Now, he needs to be at school 4 minutes earlier, time will now be 10 - 4 = 6 minutes

To get the speed here;

Recall that the distance from above does not change

So speed = 0.5/6 mph 0r 1/12 mph

Answer:

First, in standard notation, we must define our zero.

In this case, would make sense to define the zero in the surface of the water.

(below is a number line so you can see the process to think this)

Then if the whale is swimming 60ft bellow the surface of the water, then the first position of the whale is:

-60

Now the whale goes up 30ft, then the new position of the whale is:

-60ft + 30ft = -30ft.

The correct option is A:

The equation is -60 + 30 = -30. The whale is 30 feet below the water's surface.

(you wrote that the equation was equal to +30 instead of -30 in the option A, i supposed that it was a typo)

Answer:

93 large, 3 medium

the first thing you gotta do is find the least amount of the smaller number that you can take away until it becomes a  multiple of the largest number.

1356-12(1)

1344-12(2)

1332-12(3)

1320 12 factored into 1356 3 times before we reached a multiple of 15 so we subtract 3 from the total number of pizza sold and we have 93 large pizzas and 3 medium pizzas

Answer:

n = 2

Step-by-step explanation:

Simplifying

(n + 8) + (n + -12) = 0

Reorder the terms:

(8 + n) + (n + -12) = 0

Remove parenthesis around (8 + n)

8 + n + (n + -12) = 0

Reorder the terms:

8 + n + (-12 + n) = 0

Remove parenthesis around (-12 + n)

8 + n + -12 + n = 0

Reorder the terms:

8 + -12 + n + n = 0

Combine like terms: 8 + -12 = -4

-4 + n + n = 0

Combine like terms: n + n = 2n

-4 + 2n = 0

Solving

-4 + 2n = 0

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + 2n = 0 + 4

Combine like terms: -4 + 4 = 0

0 + 2n = 0 + 4

2n = 0 + 4

Combine like terms: 0 + 4 = 4

2n = 4

Divide each side by '2'.

n = 2

Simplifying

n = 2

Step-by-step explanation:

[tex]x {}^{2} + 3x - 18 \\ = x {}^{2} + (6 - 3)x - 18 \\ = x {}^{2} + 6x - 3x - 18 \\ = x(x + 6) - 3(x + 6) \\ = (x + 6)(x - 3)[/tex]

Answer:

(03.01) The domain of a relation is the output (y) values of the relation the input (x) values of the relation a set of points that pair input values with output values x and y values written in the form (x, y)

{-2, -1, 0, 1, 2, 3} representing the domain of the relation.

A relation is a function if it has only One y-value for each x-value.

To determine the domain of a relation, we need to identify all possible values for the input or independent variable.

In this case, without any further information, we can look for the set of numbers provided in the answer choices and determine which set includes all possible values for the input.

Looking at the given answer choices:

A. {-1, 0, 1, 3}

B. {-2, 0, 1, 3}

C. {-2, -1, 0, 1, 2, 3}

D. {0, 1, 2, 3}

Since there is no specific information or restrictions mentioned, the most inclusive set that covers all possible values for the input variable is {-2, -1, 0, 1, 2, 3}.

Therefore, {-2, -1, 0, 1, 2, 3}, representing the domain of the relation.

Answer:

Maggie is 7 years old

Step-by-step explanation:

m+2m-4=17

3m-4=17

3m=21

m=7

Answer:

Maggie is seven years old

Step-by-step explanation:

Maggie's Brothers Age = B

Maggie's Age = M

2M - 4 = B

B + M = 17

Plug in 2M - 4 for B

( 2M - 4 ) + M = 17

Combine Like Terms

3M - 4 = 17

Add 4 to either side

3M = 21

Divide either side by 3

M = 7

Check your answer

2M - 4 = B -> 2 x 7 - 4 = B -> 14 -4 = B -> B = 10

B + M = 17 => 7 + 10 = 17 => 17 = 17

Answer:

12

Step-by-step explanation:

Since M is a midpoint of LN, we can see 3x equal to x+8. Remove 1 x to get 2x=8. Solve for x to get x=4. Note that this is not the end to your problem. They asked for the length of MN, not the value of x. Plugging x into MN give you 4+8, which is 12.

(If you need to show work, here it is)

3x=x+8

2x=8

x=4

MN=x+8

MN=4+8

MN=12
