If Eric agreed to make monthly payments of 175.00 for 36 months, the total amount of money he will pay the bank is 6,300.

Given that;

To determine the total amount of money that Eric will pay the back, we simply multiply his monthly payment and the number of months.

175.00 × 36

= 6,300

Hence, if Eric agreed to make monthly payments of 175.00 for 36 months, the total amount of money he will pay the bank is 6,300.

Answer:

horizontal asymptote of y = -7

Step-by-step explanation:

The parent function is shown on the coordinate plane. The graph of the parent function has a horizontal asymptote (an imaginary line that the graph approaches, but never touches or intersects) of y = 0.

Since the function of g(x) = e^x - 7 is the graph of the parent function translated 7 units down, the function would have a horizontal asymptote of y = -7.

There are 31 possible lengths for the third side.

Unknown Side +  16 > 21

So, the possible integer lengths range from

Answer: 0.001389

Step-by-step explanation:

Since you have 6 probabilities that it could be red, you get 1/6. Now, you took 1 probability out of 6, so now you only have 5. So you multiply 1/6 by 1/5. Now you have only 4 cards. Multiply 1/ 6 * 1/5 * 1/4 and keep going (e.g 1/6 * 1/5 * 1/4 * 1/3 * 1/2 * 1). This comes out to 0.00138888888, or rounded to six decimal places, 0.001389.

the given points are

(6, 4)

so, can you see, how the sequence continues ?

I see immediately that for every 3 additional units of x we add 2 units of y.

so, yes, the next point in the sequence is

(6 + 3, 4 + 2) = (9, 6).

so, this point (or ordered pair) follows the same ratio or proportional relationship between x and y as the points already in the graph.

in other words, they are on the same line following the same slope ("y coordinate change / x coordinate change" when going from one point on the line to another).

Answer:

40.6°

Step-by-step explanation:

The building and the shadow are perpendicular to each other (or intersect at a 90° angle).

Meaning that this is a triangle problem.

We are making a triangle from the building to the shadow and a diagonal line connecting the ends of both.

We need to find the angle at the top of the building. The opposite side of the angle is 84. The adjacent side is 98.

Opposite / Adjacent = Tan X

So if we go to the calculator:

[tex]tan^{-1} (\frac{84}{98}) = 40.6[/tex]

The answer is 40.6 degrees.

The simplified expression that represents the total perimeter of the triangle is 2x^2 + 10x  + 3

The side lengths are given as:

2x^2 + 5x + 3, 2 + 2x and 3x - 2

Add these lengths to determine the perimeter (P)

P = 2x^2 + 5x + 3 + 2 + 2x + 3x - 2

Collect like terms

P = 2x^2 + 5x + 2x + 3x  + 3 + 2 - 2

Evaluate the like terms

P = 2x^2 + 10x  + 3

Hence, the simplified expression that represents the total perimeter of the triangle is 2x^2 + 10x  + 3

Answer:

A(5 ; 8)

Step-by-step explanation:

y = 5x - 17

y = x + 3

    5x - 17 = x + 3

⇔ 5x - x = 3 + 17

⇔ 4x = 20

⇔ x = 20/4

⇔ x = 5

y = 5 + 3 = 8

So (5 ; 8)

Answer:

We can use the substitution method to solve the system of equations.

Since y = x + 3, we can substitute this expression for y in the first equation:

y = 5x - 17

x + 3 = 5x - 17

Subtracting x from both sides, we get:

3 = 4x - 17

Adding 17 to both sides, we get:

20 = 4x

Dividing both sides by 4, we get:

x = 5

Substituting this value of x into either equation, we get:

y = x + 3 = 5 + 3 = 8

Therefore, the correct ordered pair is (5, 8), which corresponds to the point where the two lines intersect.

The correct answer is (A) (5,8).

Answer:

x = 108°

y = 72°

z = 36°

Step-by-step explanation:

   If all sides are equal in a pentagon, then it is a regular pentagon.

n = the number of sides = 5

Sum of all angles in a pentagon = (n -2) * 180

                                                     = (5 - 2)* 180

                                                     = 3 *180

                                                     = 540°

Sum of each angle of regular pentagon = 540 ÷ 5

                                                                  = 108°

  [tex]\sf \boxed{\bf x= 108^\circ}[/tex]

Linear pair: If the non common arm of adjacent angles form a straight line, then the adjacent angles are called linear pair and they add up to 180°

∠DCB + y = 180 °   {Linear pair}

  108  + y = 180

            y = 180 - 108

            [tex]\sf \boxed{\bf y = 72^\circ}[/tex]

Exterior angle property of triangle: The exterior angle equals the sum of opposite interior angles.

In Δ BCF ,

  x = y + z

Now, substitute the values of x and y , and we can find the value of z.

      108° = 72 + z

108  - 72 = z

The equation of an ellipse for the graph shown is [tex]\frac{x^2}{5^2} + \frac{y^2}{21^2} = 1[/tex]

Since the given coordinates of the vertices and foci have the form (-5, 0) and (5, 0) and (-2, 0) and (2, 0) respectively, this ultimately implies that the major axis of this ellipse is the x-axis.

Thus, the standard form of the equation of this ellipse is given by:

[tex]\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1[/tex]

Next, we would solve for b² by using this equation:

b² = a² - c²

b² = 5² - 2²

b² = 25 - 4

b² = 21.

Substituting the parameters into the standard equation of an ellipse, we have;
