A basketball court is shaped like a rectangle. It has a perimeter of 288 feet. The width of the court is 50 feet. What is the length of the court? Use the following formula to help you decide: Pr = 2l + 2w where Pr is the perimeter of a rectangle, l is the length, and w is the width
using the given formula, fill in the numbers where they belong
perimeter = 288
width = 50
so Pr = 2l + 2w becomes
288 = 2l +2(50)
288 = 2l +100
subtract 100 from each side
188 =2l
divide both sides by 2
l = 188 /2
l = 94
length = 94 feet
P (1.23 < z < 3.24) =
The value of the P (1.23 < z < 3.24) is 0.49 after using the Z table and concept of the probability.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is given that:
P (1.23 < z < 3.24)
As we know, from the normal distribution, It's the probability curve of a continuous distribution that's most likely symmetric around the mean.
On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.
From the Z curve:
P (1.23 < z < 3.24) = 0.49
Thus, the value of the P (1.23 < z < 3.24) is 0.49 after using the Z table and concept of the probability.

Maricella plots two ordered pairs on the grid below.
Answer:
B. [tex](0,-10)[/tex]
Step-by-step explanation:
We have been given an image of a line segment on coordinate plane. We are asked to find the y-intercept of line, is the line segment is extended to cross both the axes.
We will find the equation of line in slope-intercept form: [tex]y=mx+b[/tex], where,
m = Slope of line,
b = The y-intercept.
We will find slope of our given line using the coordinates of our given points (6,2) and (8,6).
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{6-2}{8-6}[/tex]
[tex]m=\frac{4}{2}[/tex]
[tex]m=2[/tex]
Now, we will substitute [tex]m=2[/tex] and coordinates of point (8,6) in slope-intercept form of equation.
[tex]6=2*8+b[/tex]
[tex]6=16+b[/tex]
[tex]6-16=16-16+b[/tex]
[tex]-10=b[/tex]
Since y-intercept of our given line is [tex]-10[/tex], which is at [tex]x=0[/tex], therefore, option B is the correct choice.

bo has 23 video games for sale he plans to donate the money he makes from each sale to a local charity what is the least amount of money in whole dollars bo should charge for each game in order to raise 100$
Answer: $5
Step-by-step explanation:
Let x be the least charge for each video game.
Given : Total games for sale =23
The required minimum amount needed to raise by selling video games =$100
Then the required inequality:
Total games × x ≥ Required minimum amount
i.e. [tex]23x\geq100[/tex]
Divide 23 from both sides , we get
[tex]x\geq 4.34782608696\approx5[/tex]
Hence, Bo should Charge $5 for each game in order to raise 100$.

The Soup Shack usually makes tomato soup with 9 tomatoes for every 12 cups of soup. Today, they made 8 cups of soup with 6 tomatoes. How does today's soup compare to the usual recipe?
Answer: We compare today's soup to the usual recipe by using "Unitary Method".
Step-by-step explanation:
Since we have given that
The Soup Shack makes tomato soup with 9 tomatoes for every 12 cups of soup.
For every 12 cups of soup , 9 tomatoes is needed
For every 1 cup of soup , the number of tomato is needed is given by
[tex]\frac{9}{12}=\frac{3}{4}[/tex]
Today, they made 8 cups of soup with 6 tomatoes ,
For 8 cups, 6 tomatoes are used .
For 1 cup, number of tomato is used is given by
[tex]\frac{6}{8}=\frac{3}{4}[/tex]
So, we can see that both the soup has same quantity .
∴ We compare today's soup to the usual recipe by using "Unitary Method".

Which of the following is a situation in which an equation cannot be solved using the quadratic formula? A.) The coefficient of the x^2 term is zero B.) The right hand side of the equation is zero C.) The coefficient of the x term is zero D.) The degree of the polynomial is 2
Final answer:
An equation cannot be solved using the quadratic formula if the coefficient of the [tex]x^{2}[/tex] term is zero, as this makes it a linear equation, not a quadratic. So, option A is correct.
Explanation:
The situation in which an equation cannot be solved using the quadratic formula is when the coefficient of the [tex]x^{2}[/tex] term is zero (A). An equation is only quadratic if it is of the form a[tex]x^{2}[/tex] + bx + c = 0, where 'a' is not equal to zero. If 'a' is zero, the equation is not a quadratic equation but a linear one, and the quadratic formula cannot be applied. The quadratic formula, 'x' equals minus 'b', plus-or-minus the square root of 'b' squared minus four 'a' 'c', all over two 'a', requires a nonzero 'a' value because the denominator of the formula includes '2a'. If 'a' is zero, the formula would involve division by zero, which is undefined.
Option B is incorrect because having zero on the right-hand side of the equation does not affect the use of the quadratic formula. Likewise, option C is incorrect because the equation can still be quadratic even if the coefficient of the x term ('b') is zero; the equation becomes a pure quadratic equation. Option D suggests the polynomial is already of degree 2, which is the correct type of equation to apply the quadratic formula.

Maricella plots two ordered pairs on the grid below.
Answer: (0,-10)
Step-by-step explanation:
The equation of a line (a,b) and (c,d) is given by :-
[tex](y-b)=\dfrac{d-b}{c-a}(x-a)[/tex]
From the given graph , the line is passing through (6,2) and (8,6) is given by :_
[tex](y-6)=\dfrac{6-2}{8-6}(x-8)\\\\\Rightarrow\ y-6=\dfrca{4}{2}(x-8)\\\\\Rightarrow\ y-6=2(x-8)\\\\\Rightarrow\ y=2(x-8)+6[/tex]

find the formula for the graph of function f(x) given in the graph above
The given graph is scaled form of trigonometric function graph.
The formula for the graph function f(x) is given by:
[tex]f(x) = -2sin(\dfrac{x}{4})[/tex]
How to find the formula for f(x) for given graph?Note down the properties one by one.
Firstly its a periodic function.
Secondly, the maximum value of the function is 2 and minimum value is -2
Thirdly the function assumes maximum or minimum value when it reaches to [tex]2 \pi n; n \in \mathbb Z[/tex]
Fourthly, the graph from the center to right side goes down then up then down then up and so on.
If you've seen graph of sine function, then you'd know that the graph is periodic(repeating same values after some interval), the maximum and minimum values being 1 and -1 and maximum or minimum values are achieved when input is [tex]\dfrac{n\pi}{2}; \: n \in \mathbb{Z}[/tex]
Plus, the graph from center to right goes up then down then up then down and so on.
Transforming sine graph to make the given graph:First we need down then up instead of up and down. Since down is negative output in its graph and up is positive, thus we will negate the value of sine function.
[tex]-sin(x)[/tex] will have flipped mountains and valley's in comparison to that of sin(x).
Now since the maximum and minimum values are needed to be 2 and -2 instead of 1 and -1, thus we will scale the output with factor of 2.
[tex]-2sin(x)[/tex] will have maximum and minimum as 2 and -2 respectively.
We need the graph to be maximum or minimum at x = [tex]2 \pi n; n \in \mathbb Z[/tex] and not at x = [tex]\dfrac{n\pi}{2}; \: n \in \mathbb{Z}[/tex]. Thus, we will scale down the input of -2sin(x) so that it treats [tex]2 \pi n; n \in \mathbb Z[/tex] as if it was given [tex]\dfrac{n\pi}{2}; \: n \in \mathbb{Z}[/tex].
The scaling needs to be by 1/4 since [tex]\dfrac{1}{4} \times 2\pi n = \dfrac{n\pi}{2}[/tex]
Thus, the resultant function is [tex]-2sin(\dfrac{x}{4})[/tex]
The below plotted graph shows graph of sin(x) (in red) and that of [tex]-2sin(\dfrac{x}{4})[/tex] (in blue).
