Write the equation of a line parallel to the line y=2x
Answer:
to create an equation that is parallel to a line, you keep the slope or rate of change the same, all you do is change the y intercept. so you have to keep
y = 2x, but then you can add any number to the end.

Answer:
x = 33.13 units
Step-by-step explanation:
Let the altitude of the triangle be h units.

Answer:
x = 23.7926Step-by-step explanation:
Step 1
Find the length of vertical line segment, lets call it h. Use function cos
h/31 = cos 66°h = 31 * cos 66° = 31*0.4067 = 12.6077Step 2
Find x using another function, sin
h/x = sin 32°x = h / sin 32°x = 12.6077 / 0.5299x = 23.7926Find the distance between E(5,3) and F(-4,3).

Step-by-step explanation:
Michael wants to purchase a jeep. The purchase price of the Jeep is $37,000. The
dealership will allow him to pay cash or finance the Jeep with a down payment of
$5,000.00 and 60 monthly payments of $625.00. Michael chose to finance the jeep.
Answer the following questions.
a) What is the amount financed?
b) What is the total amount of monthly payments?
C} What is the amount of the finance charge?
Answer:
A) $32,000 B) $37,500 C) $5,500
Step-by-step explanation:
Price of jeep: $37,000
Michael uses $5,000 of his own money toward that total $37,000-$5,000= $32,000
Monthly payments $625.00×60months=$37,500
After paying $5,000 of his own money, & bringing theamount owed to $32,000. Michael still has to pay back $37,500. Making, the finance chardge $5,500. ($37,500-$32,000= $5,500)
Amount financed = $32000, total amount of monthly payment = $37500 and total amount of the finance charge = $5500.
What is dealership finance ?
"Dealer financing is a type of loan that is originated by a retailer to its customers and then sold to a bank or other third-party financial institution. The bank purchases these loans at a discount and then collects principle and interest payments from the borrower. This is also called an indirect loan."
According to the question,
Given,
Price of jeep = $37000
Down payment = $5000
Total number of monthly payment = 60
Amount to be paid after down payment
= $37000 - $5000
= $32000 ____( 1 )
Amount paid in Monthly payments = $625.00 × 60months
= $37500 ____( 2 )
From ( 1 ) and ( 2 ) we get,
Finance charge amount = Total monthly amount - Total amount financed
= $37500 - $32000
= $5500
Hence, amount financed , total amount monthly payment and total amount of the finance charge is $32000 , $37500 and $5500.

What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.equation modelling : Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis and results of the given problemGiven is that a baby is 18in long at birth and 27in long in ten months
At birth, the length of baby = 18 inches.
After 10 months, the length of the baby = 27 inches.
Increase in length per month will be -
r = (27 - 18)/(10 - 0)
r = 9/10
r = 0.9 inch
Therefore, the length of the baby will increase 0.9 inch per month.

I need help with this can someone help me I have a few other ones as well I don’t understand anyone?
Answer:
x=59
Step-by-step explanation:
The sum of the interior angles of a triangle add up to 180 degrees. That means that (x+12)+(x)+(x-9)=180 degrees in total. If we combine the like terms (combine the xs and regular constant values), the xs add up to 3x (x+x+x) and the regular constants add up to 3 (12+-9=3). If we rewrite this in a more simplified form, we get 3x+3=180. Subtract 3 on both sides to get 3x=177 because we want to isolate x. 3x=177 divide 3 on both sides and we get 59. x=59

Determine an expression for dy
dx given that x = sin3
(t)andy = cos3
(t)
Answer:
[tex]\frac{dy}{dx} =-\sqrt[3]{\frac{y}{x} }[/tex]
Step-by-step explanation:
Recall that using the chain rule we can state:
[tex]\frac{dy}{dt} =\frac{dy}{dx}*\frac{dx}{dt}[/tex]
and therefore solve for dy/dx as long as dx/dt is different from zero.
Then we find dy/dt and dx/dt,
Given that
[tex]x=sin^3(t)\\dx/dt = 3 sin^2(t)* cos(t)[/tex]
And similarly:
[tex]y=cos^3(t)\\dy/dt=-3\,cos^2(t)*sin(t)[/tex]
Therefore, dy/dx can be determined by the quotient of the expressions we just found:
[tex]\frac{dy}{dx} =\frac{dy/dt}{dx/dt} =\frac{-3\,cos^2(t)*sin(t)}{3\,sin^2(t)*cos(t)} =-\frac{cos(t)}{sin(t)}[/tex]
now notice that we can find [tex]cos(t) = \sqrt[3]{y}[/tex] from the expression for y,
and [tex]sin(t) = \sqrt[3]{x}[/tex] from its expression for x.
Therefore dy/dx can be written in terms of x and y as:
[tex]\frac{dy}{dx} =-\frac{cos(t)}{sin(t)}=-\sqrt[3]{\frac{y}{x} }[/tex]

Suppose a random sample of n=330 tenneagers 13 to 17 years of age was asked if they use social media. Of those surveyed, 252 stated that they do use social media. Find the sample proportion of tenneagers 13 to 17 years of age who use social media
Answer:
what is
Step-by-step explanation:
The sample proportion of the teenagers 13 to 17 years of age who use social media is 0.236.
What is a Sample Proportion?Sample proportion is defined as the proportion of something from a given sample which has a particular characteristic.
The formula to calculate the sample proportion is,
p = Number of successes in a particular sample / Sample size
Given that,
a random sample of n = 330 teenagers 13 to 17 years of age was asked if they use social media.
Sample size = 330
Of those surveyed, 252 stated that they do use social media.
We have to find the proportion of teenagers 13 to 17 years of age who use social media.
Number of failures = 252
Number of successes = 330 - 252 = 78
Sample proportion = 78 / 330 = 0.236
Hence the sample proportion is 0.236.

y= -2x+8
what is the value of y when 0 is the value of x?
Not sure what you mean but will be explaining about y = 0 and x =0 anyway.
So for x = 0, that means the value of x is 0.
y = -2(0)+8
y=0+8
y=8
So when x = 0, the value of y is 8 (y = 8) or we can write (0,8)
For y = 0, that means the value of y is 0.
0=-2x+8
-8=-2x
-2x=-8
x=4
So when y = 0, x = 4. We can write as (4,0)
