Use the graph to solve. A table tennis ball that has been hit is about 13.69 times as fast as the speed for the swimming. What is the speed for the table tennis ball? Hurry
Answers
The speed of the table tennis ball is 29.9303 m/s.
What is speed?The speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is a scalar quantity and does not require any direction to represent it.
Fastest speed of the swimmer recorded = F =2.29 m/s
The fastest Speed of the table tennis ball been hit = b
According to the question: The speed of a table tennis ball has been hit about 13.07 times as fast as the speed for the fastest swimming.
The speed will be calculated as below:-
Speed = 13.07 x f
Speed = 13.07 x 2.29
Speed = 29.93 meter per second
Therefore, speed of the table tennis ball is 29.9303 m/s.

An expression that can be used to find the cost of an n-minute long distance call, where n is at least 5 minutes is (0.55 + (n - 5) x 0.07) dollars.
Given:
Long Distance Rates Time (minutes) Cost5 $0.556 $0.627 $0.698 $0.769 $0.8310 $0.90We need to find an expression that can be used to find the cost of an n-minute long-distance call, where n is at least 5 minutes.
The cost of making a long-distance call is given for 5 minutes, 6 minutes, 7 minutes, 8 minutes, 9 minutes, and 10 minutes.
We can observe from the above table that for every increase of 1 minute, the cost increases by $0.07.
We can conclude that the cost of n minutes long-distance call is given by: (0.55 + (n - 5) x 0.07) dollars when n is at least 5 minutes.
Therefore, the required expression is: (0.55 + (n - 5) x 0.07) dollars when n is at least 5 minutes. The above expression is based on the pattern in the table provided for long-distance call rates. We can use this expression for values of n greater than or equal to 5.

Hello could you please help me with these questions? Question 12.

The general form of the equation of a straight line in the slope-intercept form is given to be:
\(y=mx+b\)where m is the slope of the line and b is the intercept on the y-axis, that is the y-value when x = 0.
To calculate the slope, we can use the formula:
\(m=\frac{y_2-y_1}{x_2-x_1}\)From the question provided, we have the points:
\(\begin{gathered} 1\Rightarrow(x_1,y_1)=(-1,-2) \\ 2\Rightarrow(x_2,y_2)=(3,4) \end{gathered}\)Using these values, we can calculate the slope to be:
\(m=\frac{4-(-2)}{3-(-1)}=\frac{4+2}{3+1}=\frac{6}{4}=\frac{3}{2}\)Hence, we have the equation of the line to be:
\(y=\frac{3}{2}x+b\)We currently do not have a value for b. We can find b, however, by substituting a point into the equation. Then we can solve for b. Using the second point, we have:
\(\begin{gathered} 2\Rightarrow(x,y)=(3,4) \\ \therefore \\ 4=\frac{3}{2}(3)+b \\ 4=\frac{9}{2}+b \\ b=4-\frac{9}{2} \\ b=-\frac{1}{2} \end{gathered}\)Therefore, the equation of the line is:
\(\begin{gathered} y=\frac{3}{2}x-\frac{1}{2} \\ or \\ y=1.5x-0.5 \end{gathered}\)Solve the following quadratic inequality x^2+x-6>0
Answers
Answer:
x < -3 or x > 2
Step-by-step explanation:
x² + x - 6 > 0
Convert the inequality to an equation.
x² + x - 6 = 0
Factor using the AC method and get:
(x - 2) (x + 3) = 0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
x - 2 = 0
x = 2
x + 3 = 0
x = -3
So, the solution is x < -3 or x > 2

Using product rule on the differential equation y = (x² + x + 1)(x³ - x - 1), the value of y'(2) = 118
Differential EquationA differential equation is an equation which contains one or more terms and the derivatives of one variable (i.e., dependent variable) with respect to the other variable (i.e., independent variable) dy/dx = f(x) Here “x” is an independent variable and “y” is a dependent variable.
In the function given
y = (x² + x + 1)(x³ - x - 1)
Using product rule
dy / dx = U dv/dx + V du/dx
where;
U = x² + x + 1V = x³ - x - 1du / dx = 2x + 1
dv / dx = 3x² - 1
dy/dx = 5x⁴ + 4x³ - 4x - 2
y'(2) = dy/dx(2) = 5(2)⁴ + 4(2)³ - 4(2) - 2
y'(2) = 118

y = 20x + 200
Step-by-step explanation:
The 200 is the constant. It is only added once, but the monthly deposits are added at 20 every month.
After 1 month:
y = 20x + 200
y = 20(1) + 200
y = 20 + 200
y =220 money deposited.
After 2 months:

Answer:
See explanation
Step-by-step explanation:
Selected theme park admission prices has the lower standard deviation.
Specific home stereo system's distribution is more spread out since the ratio between the standard deviation and the mean is greater compared to that of selected theme park admission prices.

The total profit in all was \(1040-900=\$ 140\).
The total profit per pizza was \((0.50)(8)=\$4\).
This means they sold \(\frac{140}{4}=35\) pizzas.

Answers
Answer:
ok.
1. Tanya spends exactly $30.
She can spend $15.00 each for 2 t shirts and spend $30.00
15 x 2 = 30
She can buy one $15.00 t shirt, one $10.00 t shirt and one $5.00 t shirt for exactly $30.00.
15 + 10 + 5 = 30
She can buy one $15.00 t shirt, and three $5.00 t shirts for exactly $30.00
15 + 5 + 5 +5 = 30
2. To spend exactly $25.00, Tanya can spend it :
5 of the $5.00 t shirts
5 x 5 = 25
2 of the $10 t shirts and one of the $5 t shirts
10 + 10 + 5 = 25
1 of the $15 t shirts and one of the $10 t shirts
15 + 10 = 25
1 of the $15 t shirts and 2 of the $5 t shirts
