Answer:

(-) $29.26 per thousand for a 3-year 3.4% loan

(a) $5,240

(b) $153.32

(c) $279.52

Step-by-step explanation:

• Payment per thousand

The payment amount can be computed from the formula ...

A = P(r/n)/(1 -(1 +r/n)^(-nt))

where P is the principal amount, r is the annual rate, n is the number of payments per year, and t is the number of years.

For a $1000 3-year loan at 3.4%, this evaluates to ...

A = 1000(0.034/12)/(1 -(1 +0.034/12)^(-12·3)) ≈ $29.26

The monthly car payment per $1000 borrowed is $29.26.

__

• Rudy's trade-in allowance and down payment will reduce the amount he finances to ...

$10,240 -3000 -2000 = $5,240

__

• $5,240 = 5.24 × $1000, so Rudy's payment will be ...

5.24 × $29.26 = $153.32

__

• The amount of interest Rudy pays is the difference between the amount paid back and the amount of the loan.

(36 mo)×($153.32/mo) - 5240 = $279.52

Monthly Car Loan Payment Per $1000 Borrowed is $29.26

(a) money he will borrow for loan = $ 5240

(b) monthly auto payment = $ 153.32

(c) the total amount of interest he will pay is $279.52

(d) Total payment for car= $ 10,519.52

Given Information :

We find out the monthly car loan payment for every $1000 borrowed.

Lets use monthly payment formula

[tex]A=\frac{P\cdot \frac{r}{n} }{1-(1+\frac{r}{n})^{-nt} }[/tex]

Where P is the loan amount.

r is the rate of interest and t is the number of years

n is the period

P=1000

Given that  3-year auto loan at 3.4% APR.

t=3, r= 3.4%= 0.034, n=12

Substitute all the values and calculate the monthly loan

[tex]A=\frac{P\cdot \frac{r}{n} }{1-(1+\frac{r}{n})^{-nt} }\\A=\frac{1000\cdot \frac{0.034}{12} }{1-(1+\frac{0.034}{12})^{-12\cdot 3} }\\A=\frac{1000\cdot \frac{0.034}{12}}{1-\left(\frac{0.034}{12}+1\right)^{-36}}\\A=\frac{2.83333\dots }{1-1.00283\dots ^{-36}}\\A=29.25782[/tex]

Monthly Car Loan Payment Per $1000 Borrowed is $29.26

The cost of car is  $10,240. Allowance = 3000 and down payment = 2000

(a) Auto loan = cost of car - allowance - down payment

[tex]Auto \; loan = 10240 - 3000 -2000=5240[/tex]

(b) Monthly Car Loan Payment Per $1000 Borrowed is $29.26

Monthly car loan payment for $5240 is

[tex]\frac{5240}{1000} * 29.26=153.32[/tex]

(c) first we find out the total loan amount paid in 3 years (36 months)

[tex]36 \cdot 153.3224=5,519.52[/tex]

To find the amount of interest he pay , we subtract the loan amount

[tex]5,519.52-5240=279.52[/tex]

the total amount of interest he will pay is $279.52

(d) Total payment for car = down payment +total loan amount paid

Total payment for car =[tex]5000+5519.52=10,519.52[/tex]

Assumption: You don't watch the same movie twice

I will explain in 2 ways

METHOD 1: Multiplication Rule

On Saturday, you have 8 choices. On Sunday, you have 7 choices because u have already watched 1 movie on Saturday

8×7 = 56

METHOD 2: Permutation

Since 'order' is important, i.e. watching movie A on Saturday & B on Sunday is different from watching B on Saturday & A on Sunday, so it's

8P2 = 56

Using the permutation formula, it is found that you can choose a movie to see this Saturday and one to see this Sunday in 56 ways.

The order in which the movies are chosen is important, as they are respective to different days, hence the permutation formula is used to solve this question.

The number of possible permutations of x elements from a set of n elements is given by:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

In this problem, 2 movies will be chosen from a set of 8, hence:

[tex]P_{(8,2)} = \frac{8!}{6!} = 8 \times 7 = 56[/tex]

Hence, you can choose a movie to see this Saturday and one to see this Sunday in 56 ways.

Step-by-step explanation:

The mean is calculated in the usual way: the sum divided by the number of numbers.

  mean = (5 +9 +5 +5 +7 +11)/6 = 7

The deviations are the differences from the mean:

  deviation = {5, 9, 5, 5, 7, 11} -7 = {-2, 2, -2, -2, 0, 4}

and the absolute deviation is the absolute value of these numbers:

  absolute deviation = {2, 2, 2, 2, 0, 4}

The mean absolute deviation (MAD) is the average of these values:

  (2 +2 +2 +2 +0 +4)/6 = 2

The mean absolute deviation is 2.

Step-by-step explanation:

You swap the X and Y coordinate for reflections over y=x

Answer:

Its the first choice.

Step-by-step explanation:

You flip the coordinates so the point (a, b) shifts to (b, a). So point A (7, 8) shifts to (8.7).

If x varies directly with y, then :

●  Increase in x results in increase of y

●  Decrease in x results in decrease of y

●  It is represented by : x ∝ y

[tex]\mathsf{\bigstar\;\;If\;x\;varies\;directly\;with\;y\;then : \large\boxed{\mathsf{\dfrac{x_1}{x_2} = \dfrac{y_1}{y_2}}}}[/tex]

Here : x₁ = 6 and y₁ = 15 and x₂ = x₂ and y₂ = 20

Substituting the values we get :

[tex]\mathsf{\implies \dfrac{6}{x_2} = \dfrac{15}{20}}[/tex]

[tex]\mathsf{\implies x_2 = \dfrac{20 \times 6}{15}}[/tex]

[tex]\mathsf{\implies x_2 = 8}[/tex]

Answer : x = 8 when y = 20

Answer:

x = 8

Step-by-step explanation:

Given that x varies directly as y then the equation relating them is

x = ky ← k is the constant of variation

To find k use the condition x = 6 when y = 15

k = [tex]\frac{x}{y}[/tex] = [tex]\frac{6}{15}[/tex] = 0.4

x = 0.4y ← equation of variation

When y = 20, then

x = 0.4 × 20 = 8

Answer: [tex](gof)(-7) =495[/tex]

Step-by-step explanation:

Given the functions f(x) and g(x), to find [tex](gof)(x)[/tex] you need to substitute [tex]x=f(x)=x^2 + 6[/tex] into the function g(x):

Answer: (1, 2)

ANSWER

[tex]y = 3x - 17[/tex]

EXPLANATION

The given line has equation;

[tex]y - 3x = 2[/tex]

We solve for y to get;

[tex]y = 3x + 2[/tex]

The slope of this line is 3.

Since tyheline is parallel to this line, it also has slope 3.

The line passes through (6,1), we can use the slope intercept form,

[tex]y-y_1=m(x-x_1)[/tex]

We substitute the point and the slope to get;

[tex]y - 1 = 3(x - 6)[/tex]

[tex]y = 3x - 18 + 1[/tex]

[tex]y = 3x - 17[/tex]

Answer: First Option

[tex]y = 3x - 17[/tex]

Step-by-step explanation:

For a linear equation of the form

[tex]y = mx + b[/tex] the slope of the line is the constant m.

In this case we have the line

[tex]y-3x=2\\y=3x +2[/tex]

Then the slope is [tex]m=3[/tex]

If the equation of the line sought is parallel to the line [tex]y=3x +2[/tex] then by definition both lines have the same slope m = 3

Therefore the equation of the line sought is:

[tex]y = 3x + b[/tex]

Where b is a constant that represents the intersection of the line with the y axis.

[tex]b = y_0 -3(x_0)[/tex]

Where [tex](x_0, y_0)[/tex] is a point belonging to the line sought.

In this case the point is (6, 1)

So

[tex]b =1 -3(6)[/tex]

[tex]b =-17[/tex]

Finally the equation is:

[tex]y = 3x - 17[/tex]

Answer:

  No, the clay will not pour out easily. I know this because the angle of the truck bed is less than 50°, which is the minimum angle for easy pouring.

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

  Sin = Opposite/Hypotenuse

If α represents the angle of the truck bed, this means ...

  sin(α) = 9/15

We can find α using the inverse sine function:

  α = arcsin(9/15) ≈ 36.87°

We note this angle is less than 50° so we expect the clay will not pour out easily.

Using the tangent function of trigonometry, we find that the angle of the raised dump truck is approximately 30.96°. Since this is less than the necessary 50°, the clay will not pour out easily when the dump truck is raised to 9 feet.

In order to solve this problem, we need to use trigonometry, specifically the tangent function. We form a right triangle, using the truck's bed length (15 feet) as the hypotenuse, the height it's been lifted (9 feet) as the opposite, and we want to find the angle this makes with the ground.

We use the relationship in trigonometry: Tan(angle) = Opposite/Hypotenuse. Converting the values to this equation, Tan(angle) = 9/15. Solving this gives us the angle as the inverse tan of 9/15.

Using a calculator to find the Inverse tan (also known as arctan or tan^-1) of 9/15 gives us an angle, which is approximately 30.96°.

No, The clay will not pour out easily when the body of the dump truck is raised to 9 feet. I know this because the body angle of the dump truck (approximately 30.96°) is less than the necessary 50° for the clay to pour out easily.

Answer:

Final answer:

To solve the given system of linear equations, we use substitution to find y = 1/9 and then find x = 7/9 as the values that satisfy both equations.

Explanation:

The student is attempting to solve a system of linear equations. To find the values of x and y that satisfy this system, we need to use a method such as substitution or elimination. Given the system:

x = −2y + 1

13x + 8y = 11

We can substitute the expression for x from the first equation into the second equation:

13(−2y + 1) + 8y = 11

−26y + 13 + 8y = 11

−18y + 13 = 11

−18y = −2

y = −2/−18

y = 1/9

Now we can substitute this value of y back into the first equation to find x:

x = −2(1/9) + 1

x = −2/9 + 1

x = −2/9 + 9/9

x = 7/9

Therefore, the solution to the system is x = 7/9 and y = 1/9.

1,000 + 1,200 = 2,200

Answer:

No; 1,200 will cause him to exceed 2,000.

Step-by-step explanation:

Given that Brett wants to stay within his daily calorie limit of 2,000 calories, and he has already consumed 1,400 calories and burned 400 calories at the gym, the maximum additional calories he can consume without exceeding his limit is:

2,000 (daily limit) - 1,400 (already consumed) - 400 (burned at the gym) = 1,000 calories

So, Brett can consume a maximum of 1000 more calories to stay within his daily limit of 2,000 calories. Therefore, 1,200 calories is not a viable solution because it exceeds his limit by 200 calories.

The correct answer is:

No; 1,200 will cause him to exceed 2,000 calories.

Step-by-step explanation:

We do have to use Pythagorean Theorem to get the diagonal part... But we are not done after that.  It wants to know how far we have walked after going down the length, the width, and the diagonal. We are going to have to add 3 numbers at the end (3 measurements for the things I just mentioned)

5^2+2^2=c^2

29=c^2

c=sqrt(29) approx 5.4

So now we do 5+2+5.4 which is 12.4 meters

Answer:

B.  z = 2

Step-by-step explanation:

Set up the matrix like this.  I multiplied the last row by a 2 to get rid of the fractions so that's what you will see:

[tex]\left[\begin{array}{ccc}2&1&-1\\0&2&3\\-1&2&2\end{array}\right][/tex]

I used Cramer's Rule to solve for the value of y.  In order to do that you need to find the determinant of the matrix, then you need to find the determinant of the matrix after you sub the solution set into the column representing z.

Find the determinant requires that I "pick up" the first 2 columns and then drop them at the end of the matrix and do the multiplication of the majors minus the minors.  The matrix looks like this:

2    1    -1    2    1

0    2    3    0    2

-1    2    2    -1    2

The multiplication of the majors:

[(2×2×2)+(1×3×-1)+(-1×0×2)] = (8-3+0)=5

The multiplication of the minors:

[(-1×2×-1)+(2×3×2)+(2×0×1)] = (2+12+0) = 14

So the determinant of the matrix is I A I = 5 - 14 = -9

Now for the determinant of z, noted as I [tex]A_{z}[/tex] I.  Notice that I am replacing the laast column with the solution set this time:

2    1    -8    2    1

0    2    -6    0    2

-1    2    -8    -1    2

The multiplication of the majors:

[(2×2×-8)+(1×-6×-1)+(-8×0×2)] = (-32+6+0) = -26

The multiplication of the minors:

[(-1×2×-8)+(2×-6×2)+(-8×0×1)] = (16 - 24 + 0) = -8

So the determinant of I [tex]A_{z}[/tex] I = -18

Cramer's Rule is to divide I [tex]A_{z}[/tex] I by I A I:

[tex]\frac{-18}{-9}= 2[/tex]

So the value you need for z to solve for y is 2

The value of z is 2.

The correct answer is an option (B) z = 2

"It is a set of numbers arranged in rows and columns so as to form a rectangular array."

"An inverse of matrix 'B' is  a matrix such that [tex]B\times B'=I[/tex] where [tex]I[/tex] is an identity matrix."

"It is a set of equations for which we find a common solution."

For given question,

We have been given a system of equations.

2x + y - z = -8

2y + 3z = -6

-1/2x + y + z = -4

We can write the third equation as, -x + 2y + 2z = -8

So, we have system of equations,

2x + y - z = -8

2y + 3z = -6

-x + 2y + 2z = -8

We write above system of equations in matrix form as,

[tex]\Rightarrow \begin{bmatrix}2 & 1 & -1 \\0 & 2 & 3 \\-1 & 2 & 2\end{bmatrix}[/tex] [tex]\begin{bmatrix}x \\y \\z\end{bmatrix}[/tex] [tex]=\begin{bmatrix}-8 \\-6 \\-8\end{bmatrix}[/tex]

⇒ AX = B

We use inverse matrix to find the solution of given system of equations.

Pre-multiply both the sides of above equation by [tex]A^{-1}[/tex]

[tex]\Rightarrow A^{-1} AX = A^{-1}B\\\\\Rightarrow IX=A^{-1}B\\\\\Rightarrow X=A^{-1}B[/tex]

The inverse of matrix A is,

[tex]A^{-1}=\begin{bmatrix}\frac{2}{9} & \frac{4}{9} & \frac{-5}{9} \\\\\frac{1}{3} & \frac{-1}{3} & \frac{2}{3} \\\\\frac{-2}{9} & \frac{5}{9} & \frac{-4}{9}\end{bmatrix}[/tex]

So, the solution of given system of equations would be,

[tex]\Rightarrow \begin{bmatrix}x \\y \\z\end{bmatrix}=\begin{bmatrix}\frac{2}{9} & \frac{4}{9} & \frac{-5}{9} \\\\\frac{1}{3} & \frac{-1}{3} & \frac{2}{3} \\\\\frac{-2}{9} & \frac{5}{9} & \frac{-4}{9}\end{bmatrix} . \begin{bmatrix}-8 \\-6 \\-8\end{bmatrix}[/tex]

[tex]\Rightarrow \begin{bmatrix}x \\y \\z\end{bmatrix}= \begin{bmatrix}0 \\-6 \\2\end{bmatrix}[/tex]

Therefore, the value of z is 2.
