Step-by-step explanation:
This only moves the linear function up 5 units. So, before the y-intercept and the x-intercept both was (0,0). Now, the y-intercept is (0,5) because the graph was shifted up 5 units.

Can someone help me with question e please ?
Answer:
Step-by-step explanation:
a) The domain is R- all real numbers.
b) The domain is R- all real numbers.
c) we need
[tex]x^{2}-4\neq 0\\x^{2} \neq 4\\x\neq 2\\and\\x\neq -2[/tex]
So the domain is R\{-2, 2}
d)
we need
[tex]x^{2}+x-2\neq 0\\x\neq 1\\and\\x\neq -2[/tex]
So the domain is R\{-2, 1}
e)
we need: x-1>0 or x> 1
So the domain is (1,+∞)

Which rule best describes the following pattern?
8, 4, 10, 6, 12, 8, 14, ...
Answer: It decreases by four then go up by six or increase by 6.
Step-by-step explanation:
It shows the alternating increased by 2
It decreases by four then go up by six or increases by 6.
We have given the pattern is
8, 4, 10, 6, 12, 8, 14, ....
We can see that
the first number is 8 and the second is 4
8>4
from 8 to 4 it is decreasing and the 4 to 10 it is increasing and again after 10 it is decreasing a.
What is the meaning of increasing?Increasing means there is a second number is greater than the first number third number is greater than the second number and so on.
There is two pattern
8,10,12,14....
Increasing by 2
4,6,8.....
Increasing by 2
Therefore it shows the alternating increased by 2.

I need help the two select choices are reduction and enlargement
Answer:
Reduction; enlargement
Step-by-step explanation:
When the scale factor is between 0 and 1, the figure shrinks, making it a reduction in size. When its greater than 1, the figure grows, enlarging it. If the scale factor is 1, the figure stays the same and doesn't shrink or grow.
Answer:
Answer is below
Step-by-step explanation:
A dilation with a scale factor between 0 and 1 is a reduction, while a dilation with a scale factor greater than 1 is an enlargement.
If you multiply the scale factor by more than 1, the scale factor will increase, causing an enlargement. If you multiply the scale factor by between 0 and 1, the scale factor will decrease, causing a reduction.
Two random samples were taken to determine how often people in a community listen to the local radio station each month.
The first sample surveyed 15 people as they exited the bank on Main Street. The first sample found that the mean number of hours they listened to the radio each month was 20.

Joanie uses 6.4 pints of blue paint and white paint to paint her bedroom walls. 3 4 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Correct question:
Joanie uses 6.4 pints of blue paint and white paint to paint her bedroom walls. ³/₄ of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer:
The quantity of white paint she used to paint her bedroom walls is 1.6 pints
Step-by-step explanation:
Given;
total quantity of blue paint and white paint used by Joanie = 6.4 pints
she uses ³/₄ of the total quantity of the paints as blue
the remaining fraction as white paint = 1 - ³/₄ = ¹/₄
The fraction of the total quantity of paints that is white paint = ¹/₄
And,
The quantity of white paint she used to paint her bedroom walls = ¹/₄ x 6.4 pints = 1.6 pints
Then, quantity of blue paint she used = ³/₄ x 6.4 = 4.8 pints
Check:
blue paint + white pain = total
4.8 + 1.6 = 6.4 pints
Therefore, the quantity of white paint she used to paint her bedroom walls is 1.6 pints

Calcula la altura de Juan sabiendo que proyecta una sombra de 2 metros en el momento en que Pedro que mide 1,80 metros proyecta una sombra de 2,25 metros.
Answer:
La altura de Juan por lo tanto es de 1.6 metros de altura
Step-by-step explanation:
Segun los datos que se encuentran en el ejercicio, tenemos lo siguiente:
Juan proyecta una sombra de 2 metros en el momento en que Pedro que mide 1,80.
Supongamos que x es la altura de juan que tenemos que calcular.
La altura de Juan por lo tanto la podemos calcular de la siguiente manera con la siguiente formula:
x= (1.8 metros/2.25 metros)*2
x=1.6 metros
La altura de Juan por lo tanto es de 1.6 metros de altura

Step-by-step explanation:
T = [tan(2×30)+1][2cos(30)-1] ÷ (y²-x²)
T = (tan60 + 1)(2cos30 - 1) ÷ (41² - 9²)
T = (sqrt(3) + 1)(sqrt(3) - 1) ÷ 1600
T = (3-1)/1600
T = 2/1600
T = 1/800

FITNESS Alejandro is a personal trainer. For his clients to gain the maximum benefit from their exercise, Alejandro calculates their maximum target heart rate using the function f(x) = 0.85(220 – x), where x represents the age of the client. Find the inverse of this function and interpret its meaning in the context of the situation.
Answer:
1). [tex]f^{-1}(x)[/tex] = (200 - [tex]\frac{x}{0.85}[/tex])
2). Inverse function represents the age of the client and 'x' represents the maximum heart rate of the client.
Step-by-step explanation:
Function representing the maximum heart rate is,
f(x) = 0.85(220 - x)
Here x = age of the client
Equation form of the function will be,
y = 0.85(220 - x)
To get the inverse of the given function, replace 'x' by 'y' and 'y' by 'x' and solve for y.
x = 0.85(220 - y)
220 - y = [tex]\frac{x}{0.85}[/tex]
y = 220 - [tex]\frac{x}{0.85}[/tex]
Now convert this equation into a function.
[tex]f^{-1}(x)[/tex] = (200 - [tex]\frac{x}{0.85}[/tex])
Here inverse function represents the age of the client and 'x' represents the maximum heart rate of the client.

Find parametric equations for the line through point P(-4,5,2) in the direction of the vector (-6,6,-5)
The vector v (-6, 6, -5) points in the direction of itself, so we start there.
We can capture all points on the line through the origin and the point (-6, 6, -5) by scaling v by an arbitrary real number t.
The line through point P and pointing in the same direction as v is parallel to the other line that passes through the origin. Then the line we want can be obtained by translating the line through the origin by a vector p that points to (-4, 5, 2), so the vector equation for this line is
r (t ) = p + t v
r (t ) = (-4, 5, 2) + t (-6, 6, -5)
r (t ) = (-4 - 6t, 5 + 6t, 2 - 5t )
To get the parametric equations, simply take out the components:
x (t ) = -4 - 6t
y (t ) = 5 + 6t
z (t ) = 2 - 5t

Five men and eight women work in a firm’s PR office. Their employer must choose two of them to attend a conference in Chicago. What is the probability of choosing one woman and one man to attend the conference?
Answer:
P(W∩M)= 20/39= 0.51
Step-by-step explanation:
Hello!
You have a total of 13 employees in the office, 5 are men and 8 are women.
Be the events:
M: The employee is a male
W: the employee is female
If you were to choose only one employee, the probability of the employee being a man will be P(M)= 5/13 and the probability of the employee being a woman will be P(W)= 8/13.
Now you are in a situation where you have to choose two employees at random, without replacement, and need to calculate the probability of choosing one woman and one man. There is no order specified in the question so when choosing the two employees there are two possible scenarios:
"The first employee is a woman and the second employee is a man"
or
"A first employee is a man and the second employee is a woman"
Symbolically:
P(W∩M)= P((W₁∩M₂)∪(M₁∩W₂))= (P(W₁∩M₂))+P(P(M₁∩W₂))
The subindex marks the order the events appeared.
Remember "and" in the sentence marks the intersection between two events "∩" and "or" mark the union between two events "∪"
First I'll solve both intersections:
P(W₁∩M₂)= P(W₁) * P(M₂)= (8/13) * (5/12)= 10/39
As I said before, this exercise is without replacement, so the first person chosen will be out of the 13 employees of the office, but when choosing the second one the total number of employees will be reduced by one (you count out the already chosen employee)
P(M₁∩W₂)= P(M₁) * P(W₂)= (5/13)*(8/12)= 10/39
In this item is the same, for the second draft, the total of employees is reduced by one since one male has already been chosen.
⇒ Mathematically both intersections are the same so you can express their union as:
(P(W₁∩M₂))+P(P(M₁∩W₂))= 2* (P(W₁∩M₂))= 2*10/39= 20/39= 0.51
I hope you have a SUPER day!
