It would take an hour for plane A to meet plane B which is flying towards it. If the distance between them will be 200 miles after 45 minutes, how far apart are they now?
Answer:
800 miles apart
Step-by-step explanation:
0.75a+0.75b=200
0.25(a+b)=200
a+b=800 miles apart
What is an equation for a sine curve with amplitude 2, and period 4pi symbolradians?
Angles a and b are the two acute angles in a right triangle. Use the relationship between sine and cosine to find the value of b if b < α. sin(7x − 15) = cos(3x + 5)
In order for the sine and cosine to be equal, the angles must be complementary
sin (7x-15) = cos (3x+5)
7x-15+3x+5 =90 (because sum of both angles a and b must be 90)
10x -10 = 90
10x = 100
x =10
One angle = 7x-15= 7*10-15 = 70-15 =55
Other angle = 3x +5 = 3*10+5 = 30+5 = 35
Since B is less than A, A = 55 degrees and B = 35 degrees
Since we need B, B = 35 degrees

A set of data has 12 pieces of data. Which of the following statements is NOT TRUE?
A.) There are 3 pieces of data in the first quartile.
B.) There are 6 pieces of data between the first quartile and the third quartile.
C.) There are 9 pieces of data that are greater than the median.
D.) There are 3 pieces of data in the upper quartile.
Please help!!
The correct answer is C.) There are 9 pieces of data that are greater than the median. The statement that is NOT TRUE is C.) There are 9 pieces of data that are greater than the median.
To understand why option C is not true, let's review some basic concepts about quartiles and the median in a set of data:
- 3 pieces of data are less than Q1.
- 3 pieces of data are in the first quartile (Q1).
- 6 pieces of data are between Q1 and Q3 (the interquartile range, IQR).
- 3 pieces of data are in the third quartile (Q3).
- Including the median itself, 4 pieces of data are greater than or equal to the median.
This breakdown correctly accounts for all 12 pieces of data. As a result, the statement that is NOT TRUE is indeed option C:
C.) There are 9 pieces of data that are greater than the median.
Since there are 4 pieces of data that are greater than or equal to the median, option C, which asserts there are 9 such pieces, is false. The correct understanding aligns with your analysis of quartiles and the median in this dataset.

The equation of the linear regression line represents the relationship between the number of cars washed for charity, x, and the amount earned for charity, y. yˆ=10x+20 How much money can the charity expect to earn if 50 cars come in for a wash?
a $3
b $20
c $720
d $520
By substituting 50 for x in the given linear regression equation, we find that the charity can expect to earn $520 if 50 cars come in for a wash.
The equation of the linear regression line given is y=10x+20, which represents the relationship between the number of cars washed for charity (x) and the amount earned for charity (y). To find how much money the charity can expect to earn if 50 cars come in for a wash, we substitute x with 50 in the equation: y = 10(50) + 20 = 500 + 20 = 520. Therefore, the charity can expect to earn $520 if 50 cars come in for a wash.
How do you find zeros when given a quadratic relation in vertex form
In order to find the zeros in a quadratic in vertex form, you need to follow a number of steps. They have been outlined for you along with a sample problem.
y = (x - 2)^2 - 16
After getting the original form, you can place a 0 in for y. In is where the graph will cross the x-axis, so it is where you will find both of your zeros.
0 = (x - 2)^2 - 16
Now take the constant and add it to both sides. In this equation, -16 is your constant. So, we'll add 16 to both sides to begin to solve.
16= (x - 2)^2
Now we can take the square root of both sides. After we do so, we take both the positive and negative version of what we get. This is because both 4 and -4 squared is equal to 16.
+/-4 = x - 2
Now we add 2 to both sides to get us what is left of x.
2 +/- 4 = x
Now that we have a final form such as this, we can separate and get two answers for our two zeros.
2 + 4 = 6
2 - 4 = -2

let f(x)=x*2+2x-1 and g(x)=2x-4 find 2f(x)-3g(x)
Composite functions involve combining more than one functions
The value of 2f(x) - 3g(x) is [tex]2x^2 -2x-+ 10[/tex]
We have:
[tex]f(x) = x^2 + 2x - 1[/tex]
[tex]g(x) =2x - 4[/tex]
The value of 2f(x) - 3g(x) is calculated as follows:
[tex]2f(x) - 3g(x) = 2 \times f(x) -3 \times g(x)[/tex]
Substitute the values of f(x) and g(x)
[tex]2f(x) - 3g(x) = 2 \times (x^2 + 2x -1) -3 \times (2x - 4)[/tex]
Open brackets
[tex]2f(x) - 3g(x) = 2x^2 + 4x -2 -6x + 12[/tex]
Collect like terms
[tex]2f(x) - 3g(x) = 2x^2 + 4x -6x-2 + 12[/tex]
[tex]2f(x) - 3g(x) = 2x^2 -2x-+ 10[/tex]
Hence, the value of 2f(x) - 3g(x) is [tex]2x^2 -2x-+ 10[/tex]

The surface inside the circles will be painted green. The surface outside the circles will be painted white. What is the ratio of green paint to white paint?
A. π : (4 - π)
B. (4 - π) : π
C. π : (π - 4)
D. π^2 : (4 - π^2)
Answer:
The ratio of green paint to white paint is A. [tex]\pi:(4-\pi)[/tex]
Step-by-step explanation:
To find the ratio of green paint to white paint we need to divide the surface that will be painted green by the surface that will be painted white.
In the graph we can see 4 equal circles. Let be ''R'' the radius of the circles.
We can also see a square. The side of the square is 4R (because the length of the side is 4 times the radius of any circle).
The surface of a circle which radius is ''R'' is equal to :
[tex]\pi .R^{2}[/tex]
The surface inside this 4 circles is equal to :
[tex]4.\pi .R^{2}[/tex]
The surface [tex]4.\pi .R^{2}[/tex] will be painted green.
The surface outside the circles is equal to [tex]4.\pi .R^{2}[/tex] subtracted to the area of the square.
The area of the square is :
[tex](4R)^{2}=16R^{2}[/tex] ⇒
[tex]16R^{2}-4.\pi.R^{2}[/tex] is the surface that will be painted white.
If we make the division between the surfaces :
[tex]\frac{GreenSurface}{WhiteSurface}[/tex] ⇒
[tex]\frac{4.\pi .R^{2}}{16R^{2}-4.\pi .R^{2}}[/tex]
[tex]\frac{(4R^{2}).\pi}{(4R^{2}).(4-\pi)}=\frac{\pi}{4-\pi}[/tex]
We find that the ratio of green paint to white paint is [tex]\pi:(4-\pi)[/tex]

alyssa wants to build a fence around her garden to keep deer and rabbits out. the length of the fence must be at least 50 ft, but she only has 140 ft for entire perimeter
Alyssa must design a fence within a 140 ft perimeter to keep out deer and rabbits, requiring heights and depths appropriate for each animal. She may use a combination of high electric fencing for deer and buried hardware cloth for rabbits, being mindful of her perimeter constraint.
The student, Alyssa, needs to build a fence around her garden and requires the length to be at least 50 ft with a total available perimeter of 140 ft. To keep deer and rabbits out, she might consider different fence designs.
For preventing deer from entering, it's suggested to use electric fencing at least 8-10 feet tall or two parallel fences that are about 4 feet high and spaced 3 feet apart.
For rabbits, a two-foot high fence made of hardware cloth or chicken wire should be used, extended at least five inches below the ground. This will discourage rabbits from digging under the fence and protect the garden effectively.
Since Alyssa has a limited amount of fencing material, she will need to calculate the perimeter carefully to maximize the enclosed area while keeping within the 140 ft limitation. She might use lengths of sides that meet her minimum requirement and stay within her total available perimeter.
