Check the picture below.

how long will it take for it to hit the ground, or namely, what is "t" when h(t)  is 0.

[tex]~~~~~~\textit{initial velocity in feet} \\\\ h(t) = -16t^2+v_ot+h_o \quad \begin{cases} v_o=\textit{initial velocity}&100\\ \qquad \textit{of the object}\\ h_o=\textit{initial height}&0\\ \qquad \textit{of the object}\\ h=\textit{object's height}&h\\ \qquad \textit{at "t" seconds} \end{cases}[/tex]

[tex]h(t)=-16t^2+100t+0\implies h(t)=-16t^2+100t\implies \stackrel{h(t)}{0}=-16t^2+100t \\\\\\ 16t^2-100t=0\implies 4t(4t-25)=0\implies \begin{cases} 4t=0\\ t=0\\[-0.5em] \hrulefill\\ 4t-25=0\\ 4t=25\\ t=\cfrac{25}{4}\\[1em] t=6\frac{1}{4} \end{cases}[/tex]

so h(t) is 0, as you saw on the picture, at two instances, once it was on the ground, 0 seconds, or t=0, and then t = 6.25, or 6 seconds and some change later.

Step-by-step explanation:

Supplementary angles are two angles whose measures add up to 180° . The two angles of a linear pair , like ∠1 and ∠2 in the figure below, are always supplementary. But, two angles need not be adjacent to be supplementary. In the next figure, ∠3 and ∠4 are supplementary, because their measures add to 180° so

angle ∠ABC  90°  therefore subtract the 90 to 180 to get the final answer

180-90=90

Final Answer is ∠QRS 90

If the team members want to brag about how tall they are, they should use the mean height of approximately 65.14 inches.

The basketball team should use the mean height as the measure of center to brag about how tall they are.

The team’s mean height is calculated by summing up all the heights and dividing by the total number of players. In this case, the sum of the heights is 64 + 67 + 83 + 65 + 66 + 62 + 69 = 456. Dividing 456 by the total number of players (7) gives us a mean height of approximately 65.14 inches.

The team’s median height is the middle value when the heights are arranged in ascending order. In this case, the heights arranged in ascending order are 62, 64, 65, 66, 67, 69, 83. The middle value is 66 inches.

If the team members want to brag about how tall they are, they should use the mean height of approximately 65.14 inches. The mean takes into account all the heights and provides an overall average, whereas the median only represents the middle value and may not accurately reflect the heights of all the players.

Step-by-step explanation:

Sorry if its wrong

Considering that 30 out of 120 clients are willing to pay at least $95, we use the it's concept and find that there is a 0.25 = 25% probability that a customer is willing to pay at least $95.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, we suppose that 30 out of 120 clients are willing to pay at least $95, hence:

[tex]p = \frac{30}{120} = 0.25[/tex]

There is a 0.25 = 25% probability that a customer is willing to pay at least $95.

Step-by-step explanation:

x + 6y = 14

-3x + 5y = 4

x + 6y = 14

subtract 6y from both sides

x = 14 - 6y

-3(14 - 6y) + 5y = 4

-42 + 18y + 5y = 4

add 42 to both sides and simplify

23y = 46

y = 2

x = 14 - 6y

x = 14 - 6(2)

x = 14 - 12

x = 2

Answer:

$ 2.167

Let the cost of a pencil be x and that of a pen be y.

A pen costs twice as much as a pencil.

==> cost of a pen = 2 × cost of a pencil

==> y = 2x

Their total cost is $6.50

==> x + y = $6.50

since y = 2x, substituting y for 2x

==> x + 2x = 6.50

==> 3x = 6.50

dividing both sides by 3

==> x = 2.16

As per our assumption, x is the cost of one pencil.

Therefore, the cost of a pencil is $2.167

The measure of the other angle in the linear pair is: 118°.

A linear pair is formed by two angles, whose sum equals 180 degrees.

Given that one of the angles of a linear pair is 62 degrees, the measure of the other angle will be its supplement.

Thus:

The other angle = 180 - 62 = 118°

Therefore, the measure of the other angle in the linear pair is: 118°.

Answer:

[tex]y=0.2*4^{x}[/tex]

Step-by-step explanation:

Notice when x increases 1, y is 4 times the previous one, so

the function is like [tex]y=C*4^{x}[/tex]

To determine the constant C, put any pair of (x, y)

Use x = 0, y = 0.2, so

0.2 = [tex]C*4^{0}[/tex] = C * 1 = C

then [tex]y=0.2*4^{x}[/tex]

Answer:

[tex]y=(0.2)4^x[/tex]

Step-by-step explanation:

General form of the exponential function: [tex]y=ab^x[/tex]

Substituting the first point (0, 0.2) into the function:

[tex]\implies 0.2=ab^0[/tex]

As any number to the zero power always gives one, [tex]b^0=1[/tex]

[tex]\implies0.2=a \times 1[/tex]

[tex]\implies a=0.2[/tex]

Therefore, [tex]y=(0.2)b^x[/tex]

Substituting the second point (1, 1.8) into the function:

[tex]\implies0.8=(0.2)b^1[/tex]

[tex]\implies0.8=(0.2)b[/tex]

[tex]\implies b=\frac{0.8}{0.2}[/tex]

[tex]\implies b=4[/tex]

So the final exponential equation is:

[tex]y=(0.2)4^x[/tex]

Checking the equation with the remaining two points:

[tex]x=2 \implies (0.2)4^2=3.2 \ \ \ \checkmark[/tex]

Answer:

(1.5,2.5)

Step-by-step explanation:

f(x) = 2x^2 - 6x + 7

Take the first derivative and set it equal to 0 (the slope is 0 at the vertex)

f'(x) = 4x -6

0 = 4x - 6

4x = 6

x = 3/2 or 1.5

If x = (3/2), then y = 2(3/2)^2 - 6(3/2) + 7

y = 2(9/4) - 18/2 + 7

y = (9/2) - 2

y = 2.5

Answer:

[tex]f(x)=\dfrac25x+\dfrac35[/tex]

Step-by-step explanation:

The data in the table means that if you input the value of x into the function, the output will be f(x).

The first two answer options are linear functions.  If a function is linear, the ratio of the difference in y-values to the difference in x-values is always constant.

We can see that the x-values in the table increase by 3 each time, so the difference in x-values is 3.

By calculation, we can also see that the y-values increase by 6/5 each time, so the difference in y-values is 6/5.

Therefore, the ratio of differences is 6/5 ÷ 3 = 2/5 and is constant.

So the function is linear and has a slope (gradient) of 2/5

Therefore, the function is: [tex]f(x)=\dfrac25x+\dfrac35[/tex]

The steps which could be used to solve x  are add negative 3. 6 to both sides and subtract 3. 6 from both sides.

Property of equality says that by performing any mathematical operation, of both sides of a expression does not change the original value of the equation.

The expression given in the problem is,

[tex]x +3.6 = -1.7[/tex]

To isolate the terms x, add Negative 3. 6 to both sides as,

[tex]x +3.6+(-3.6) = -1.7+(-3.6)\\x=-1.7-3.6\\x=5.3[/tex]

Thus, by adding negative 3. 6 to both sides, the problem can be solved.

Instead of adding negative 3.6, subtract 3.6 from both sides in the given equation can also be work and give same result as,

[tex]x +3.6-3.6 = -1.7-3.6\\x=5.3[/tex]

Thus, a step which could be used to solve x add negative 3. 6 to both sides and subtract 3. 6 from both sides.
