A car is sold for $80, 000. Every year it loses 1/4 of its value.

a. Write an equation to represent the value of the car after 1 year.

b. Write an equation to represent the value of the car after t years.
A=P(1+ r/n)^n•t

Answers

Answer 1

An equation to represent the value of the car after 1 year is P(t) = 80,000(1 - 0.25)¹.

An equation to represent the value of the car after t years is P(t) = 80,000(1 - 0.25)^t.

How to write this equation?

Generally speaking, a physical asset that loses its value at specific period of time represent an exponential decay. Therefore, a mathematical model for any physical asset (car) that decreases by r percent per unit of time is an exponential equation of this form:

P(t) = I(1 - r)^t

Where:

P(t ) represents the value of car in dollars.t represents the time or number of years.I represents the initial value of car.r represents the decay rate.

Note: 1/4 is equal to 0.25.

For a car that loses 1/4 of its value annually, after 1 year its value is given by;

P(t) = 80,000(1 - 1/4)^1

P(t) = 80,000(1 - 0.25)¹

For a car that loses 1/4 of its value annually, after t year its value is given by;

P(t) = 80,000(1 - 0.25)^t

Answers

The circle's radius circumscribed through points, A,D and E are 2 units.

Look at the image  of the figure attached below for a better understanding of the solution :

From the given figure, we can conclude the following data:

AP = √3/2(a)  → 1 length of the median for the triangle of side a.

by putting the value of a. we get:

AP = √3/2(2)  = √3

AQ = AP + PQ = √3 + 2

Area of triangle AEΔ = 1/2 × EΔ × AQ = 1/2(2) (√3+2)

AE = AD = √(EQ)² + (AQ)²

= √(1)² + (2+√3)² = √1+4+3+4√3 = √8+4√3

= 2√2+√3

We know that,

R = abc/4Δ

R = 2(2×√2+√3)  (2√2+√3) / 4{1/2×2×(√3+2)}

R= 2{4(2+√3)} / 4(√3+2)²

after a town is abandoned, the concrete parking lots remain empty and inactive for hundreds of years. what is the most likely order of ecological succession in that area?

Answers

The correct Option (B). Succession may be defined as the change in the ecological community of the species with respect to time. Two main types of succession are primary succession and secondary succession.

The living things that accumulate in the succession is from the simple organism to the complex organism. First lichens will evade in the land. After lichens grass then shrubs and finally the trees will cover the area and convert into the forest.

Primary succession occurs in basically dead areas—regions where the soil is incapable of supporting life due to causes such as lava flows, newly created sand dunes, or glacier-left boulders.

Pioneer microorganisms, plants (lichens and mosses), grassy stage, smaller shrubs, and trees are all stages of primary succession. When there is food available, animals begin to return. The climax community stage is reached when the ecosystem is fully functional.

Brooklyn is trying to find the height of a radio antenna on the roof of a local building. She stands at a horizontal distance of 23 meters from the building. The angle of elevation from her eyes to the roof ((point AA)) is 24^{\circ} ∘ , and the angle of elevation from her eyes to the top of the antenna ((point BB)) is 38^{\circ} ∘ . If her eyes are 1.66 meters from the ground, find the height of the antenna ((the distance from point AA to point BB)). Round your answer to the nearest meter if necessary.

Answers

The height of the antenna found using trigonometric ratios is about 8 meters

What are trigonometric ratios?

Trigonometric ratios indicates the ratio of the sides of a right triangle, and have values based on the lengths of the sides of a right triangle, drawn on the coordinate plane.

The distance from the building at which Brooklyn stands = 23 meters

Angle of elevation from her eyes to the roof, θ = 24°

Angle of elevation from her eyes to the top of the antenna = 38°

Height of her eyes from the ground = 1.66 meters

[tex]tan(\theta) = \dfrac{Opposite}{Adjacent} = \dfrac{Height}{Horizontal \, distance}[/tex]

Therefore;

Height = Horizontal distance × tan(θ)

Height to the top of the roof, H₁ = Horizontal distance × tan(θ)

Therefore;

H₁ = 23 × tan(24°) ≈ 10.24

Height to the top of the antenna, H₂ = 23 × tan(38°) ≈ 17.97

Height of the antenna ≈ 17.97 - 10.24 ≈ 8

Height of the antenna is about 8 meters

what is the average increase in the number of flowers pollinated per day between days 4 and 10

Answers

The average increase in the number of flowers pollinated per day between days 4 and 10 is 39.

What is average increase?

Average increase refers to the average rate of growth that a variable experiences within a given period.

According to the given question:

The number of pollinated flowers as a function of time in days is represented by the function f(x) = [tex]3^{(x/2)[/tex]

To find the average increase in the number of flowers pollinated per day between days 4 and 10, we use the formula

{f(10) - f(4)}/{10 - 4}

Now f(10) = [tex]3^{(10/2)[/tex]

               = 243

Also f(4) = [tex]3^{(4/2)[/tex]

             = 9

Therefore average increase = {f(10) - f(4)}/{10 - 4}

                                               = (243 - 10)/10 - 4

                                               = 234/6

And we have to find the largest angle of quadrilateral.

We know that the sum of all the interior angles of quadrilaterals 360°.

Let the common multiple of angles be x,

therefore  

2x + 3x + 6x + 7x = 360°

                      18x = 360°

                         x = [tex]\frac{360}{18}[/tex]

                         x = 20°

if the mean of a population is 250 and its standard de- viation is 20, approximately what proportion of obser- vations is in the interval between each pair of values?

Answers

Observed proportions (relative frequencies) from a sample are statistics that can be used to estimate probabilities.

a) Thre is 99.73% proportion of observations is in between 190 and 310 .

b)there is 95.44% proportion of observations is in between 210 and 290 .

We have given that,

Mean of population, μ = 250

standard deviations, σ = 20

we have to calculate proportion of observations in the given interval pair.

a) pair of values are 190 and 310

Using Z-score formula,

Z =( x - μ) /σ

=> Z = (190 - 250) / 20 = -3

Similarly, Z = (310 - 250)/20 = 3

So, -3 < z < 3 and from Z score we found p-value

P(190<X<310) = P( 190-u/sd < X-u/sd < 310-u/sd)

= P( X< 310 ) - P(X<190) = P(Z < 3) - P( Z< -3 )

=0.99865 - 0.00135 0.9973 = 99.73%

b) pair is 210 and 290

Z-Score = (210-250)/20 = -2

Z-score = (290-250)/20 = 2

so, -2 < z < 2

From Z score we found p-value

P(210<X<290) = P(X<290) - P(X<210)

= P(Z< 2) - P(Z< -2)

= 0.9772 - 0.0228 = 0.9544 = 95.44%

So, the required proportion are 99.73% and 95.44% proportion of observations in each given pair.

Using triple integrals we know that the solid in question has a volume of 1024/3³ units.

What is triple integral?

Multiple integrals in mathematics is a definite integrals of a function with many real variables, such as for f.

The area of a region enclosed by the function's curve is calculated using the double integral.

It can also be used to figure out how much space is beneath the surface.

The double integral can also be used to calculate the average value of a function with two variables over the rectangular region.

So, the volume of the solid (V) in this problem must be calculated using the triple integral formula in rectangular coordinates:

The following intervals impose restrictions on the solid:

[tex]y \in\left[x^2, 16\right], x \in[-4,4], z \in[0,4][/tex]

The triple integral is currently explained as follows:

[tex]$$V=\int_0^4 \int_{-4}^4 \int_{x^2}^{16} d y d x d z$$\\[/tex]

Now we integrate three times to get the volume:

(b) Suppose 63 students in the class’s sample say Yes. Explain why this result gives strong evidence that a majority of the school’s students recycle.

Answers

Suppose if 55 students in the class’s sample say Yes so, there is not sufficient evidence that more than half of the school student recycle.

and Suppose 63 students in the class’s sample say Yes so, there is sufficient evidence that more than half or majority school student recycle.

A.)

According to given data Suppose 55 students in the class’s sample.

n = 100 and x = 55

⇒ p = [tex]\frac{55}{100}[/tex] = 0.55

hence p' = 0.50

so, p > 0.50

Z = [tex]\frac{p-p'}{\sqrt{} \frac{p'(1-p')}{n} }[/tex]

Z = [tex]\frac{0.55-0.50}{\sqrt{} \frac{0.50(1-0.50)}{100} }[/tex]

so, Z = 1

let level of significance α = 0.05

critical Z value at α = 0.05 for one tail test is 1.645

since Z = 1 < z' = 1.645

do not reject at α = 0.05

there is not sufficient evidence that more than half of the school student recycle.

B.)

According to given data Suppose 63 students in the class’s

given data,

X = 63 and n = 100

now P = 63/100 = 0.63

Z = [tex]\frac{0.63-0.50}{\sqrt{} \frac{0.50(1-0.50)}{100} }[/tex] = 2.6

since, Z = 2.6 > Z' = 1.645

⇒ reject at  α = 0.05

there is sufficient evidence that more than half or majority school student recycle.

a theater has 20 rows with 28 seats in the first row, 33 in the second row, 38 in the third row, and so forth. how many seats are in the theater?

Answers

The number of seats in the theater is 1510.

Here we have to find the number of seats in the theater.

Data given:

Total row = 20

number of seats on the first row = 28

number of seats on the second row = 33

number of seats on the third row = 38

Therefore we get the series as 28, 33, 38......., which is in arithmetic sequence.

The common difference (d) = 5

Here we have to find the sum of the series.

The formula for the sum of n term of the arithmetic sequence:

[tex]S_{n}[/tex] = n/2( 2a + (n-1)d)

    = 20/2 ( 2× 28 + (20 -1) 5)

    = 10 ( 56 + 19×5)

    = 10( 56 + 95)

    = 10 ×151

    = 1510

Therefore the number of seats is 1510.

what is the even function?

Answers

Answer:  Choice A

Reason:

Every exponent shown for choice A is an even number, which by extension points us to an even polynomial function.

Choice D has all odd exponents (think of [tex]\text{x}[/tex] as [tex]\text{x}^1[/tex]), which means choice D is an odd polynomial function.

Choices B and C have a mix of even and odd exponents for their terms. This means B and C are neither even nor odd.
