The depreciated value of the car after 12 years that Kyle buys for $58,000 today, which declines 23% annually, will be $2,520.

Depreciation is the reduction or decrease in the value of an asset over time.

Depreciation occurs because an asset is put to use, and undergoes wear and tear.

The current price of the car = $58,000

The annual depreciation rate = 23%

The depreciated value after one year = 0.77 (1 - 23%)

Let the number of years of depreciation = x

The worth of the car after 12 years = 58,000 x 0.77^x

= 58,000 x 0.77^12

= 58,000 x 0.04344

= $2,519.52

= $2,520

The car's depreciated value can be modeled by the exponential function (decay) abˣ, which yields $2,520 in this situation.

Step-by-step explanation:

Step 1

Find the lateral area

we know that

The formula to calculate the lateral area is equal to

[tex]LA=Ph[/tex]

where

P is the perimeter of the base of the prism

h is the height of the prism

In this problem we have

[tex]P=4+8+8.94=20.94[/tex] [tex]m[/tex]

[tex]h=41[/tex] [tex]m[/tex]

substitute in the formula

[tex]LA=20.94*41=858.54[/tex] [tex]m^2[/tex]

[tex]LA=859[/tex] [tex]m^2[/tex]

Step 2

Find the surface area

we know that

The formula to calculate the surface area is equal to

[tex]SA=2B+Ph[/tex]

where

B is the area of the base of the prism

P is the perimeter of the base of the prism

h is the height of the prism

In this problem we have

[tex]B=8*4/4=8[/tex] [tex]m^2[/tex]

[tex]P=4+8+8.94=20.94[/tex] [tex]m[/tex]

[tex]h=41[/tex] [tex]m[/tex]

substitute in the formula

[tex]SA=4(8)+20.94*41=890.54[/tex] [tex]m^2[/tex]

[tex]SA=891[/tex] [tex]m^2[/tex]

Using the t-distribution, it is found that the 90% confidence interval is (48.3, 48.7), hence 48.8 is not within the interval.

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which:

The critical value, using a t-distribution calculator, for a two-tailed 90% confidence interval, with 225 - 1 = 224 df, is t = 1.6517.

The other parameters are given as follows:

[tex]\overline{x} = 48.5, s = 1.8, n = 225[/tex].

Hence the bounds of the interval are given by:

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 48.5 - 1.6517\frac{1.8}{\sqrt{225}} = 48.3[/tex]

[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 48.5 + 1.6517\frac{1.8}{\sqrt{225}} = 48.7[/tex]

The 90% confidence interval is (48.3, 48.7), hence 48.8 is not within the interval.

Based on the calculations, the measure of angle YUV is equal to 42°.

A line segment refers to a part of a line that is bounded by two (2) distinct points and it has a fixed length.

Based on the information given, we can deduce the following:

From triangle UOV, we have:

∠OUV + ∠OUV + ∠UOV  = 180°

2OUV + 84 = 180

2OUV = 180 - 84

2OUV  = 96

OUV  = 96/2

OUV  = 48°

Now, we can determine the measure of angle YUV:

∠YUV = ∠YUO - ∠OUV

∠YUV = 90 - 48

∠YUV = 42°.

Answer:

42

Step-by-step explanation:

Answer:

x = -1.5 , y = 5.17

Step-by-step explanation:

Solve the system of equation using ELIMINATION (solve for x)

x + 3y = 14

-x + y = 10

Solution

x + 3y = 14 ------- equation 1  * 1

-x + y = 10 ------- equation 2  * 3

x + 3y = 14 ------- equation 3

-(-3x + 3y = 30)------ equation 4

Using the ELIMINATION METHOD.

x-(-3x) + 3y-3y = 14-30

4x = -6

x = [tex]\frac{-6}{4}[/tex]

x = -1.5

Substuting -1.5 into equation one

x + 3y = 14

-1.5 + 3y = 14

Adding 1.5 to both sides

-1.5 + 1.5 +3y = 14 +1.5

+3y = 15.5

Dividing by the coeffient of y

[tex]\frac{3y}{3} = \frac{15.5}{3}[/tex]

y = 5.166666666666

y =5.17

Therefore x = -1.5 , y = 5.17

Hi Student!

Reading the question we can pull out specific bits of information that would help us find our answer.  One of the bits of information that is useful is that we are trying to find the perpendicular line.  However, in order to determine a line that is perpendicular to the other line we first need to determine the slope of the first line.  Looking at the equation given, we can see that it follows the y = mx + b form where m is the slope and in this case our slope is 8.

Now that we have completed the information gathering, we can move onto the next part which is determining a slope that is perpendicular to that of the original line.  In order to find that we first need to negate our slope which would turn our 8 into a -8.  The second step that we need to do is take the reciprocal of the number which means that we basically flip the number and so we convert -8 into -1/8.  Looking at the given options, there is none that match our answer so that either means that the question is wrong or the choices that are given are wrong.

20+25=45ft²

Answer:

C)  45 ft²

Step-by-step explanation:

Formulae

Area of a square = x²  (where x is the side length)

Area of a triangle = 1/2 × base × height

The surface area of a square pyramid comprises:

⇒ area of square base = 5² = 25 ft²

⇒ area of triangular face = 1/2 × 5 × 2 = 5 ft²

⇒ Total surface area = area of square base + 4 triangular areas

                                   = 25 + 4(5)

                                   = 25 + 20

                                   = 45 ft²
