Answers

The answer is c 140.74 bucks or pound

Based on the information given will be the value of the piano after 16 years is : C. $140.74.

Using this formula

Time=Principal(1-rate)^n

Where:

Principal=$5,000

Rate=20%

Number of year=16 years

Let plug in the formula

Time=5,000(1-0.20)^16

Time=5,000(.80)^16

Time=$140.737

Time= $140.74 (Approximately)

Inconclusion  the value of the piano after 16 years is : C. $140.74.

One afternoon, a student who is 5 feet 4 inches tall measured shadows to find the height of a telephone pole. The student's shadow was 5 feet long. At the same time, the shadow of the telephone pole was 18 feet 9 inches long. How tall is the telephone pole?





Please help

Answers

Answer:

19.9875 feet

Step-by-step explanation:

The formula is given as:

Shadow of the student/Height of the student = Shadow of the telephone pole/Height of the telephone pole.

1 inch = 0.0833 feet

Shadow of the student = 5ft

Height of the student = 5 feet 4 inches

4 inches to feet

= 4 × 0.0833 feet

= 0.33 feet

Hence: Height of the student = 5 + 0.33 = 5.33 feet

Shadow of the telephone pole = 18 feet 9 inches long

9 inches to feet

= 9 × 0.0833 feet

= 0.75 feet

Hence: Shadow of the telephone pole = 18 + 0.75 = 18.75 feet

Height of the telephone pole= x

Therefore:

5/5.33 = 18.75/x

Cross Multiply

5x = 5.33 × 18.75

x = 5.33 × 18.75/5

x = 19.9875 feet

The height of the telephone pole = 19.9875 feet

Dan buys a car for £700.
It depreciates at a rate of 5.5% per year.
How much will it be worth in 6 years?
Give your answer to the nearest penny where appropriate.

Answers

Answer:

£469

Step-by-step explanation:

So 6 years mean it has depretiatied to 5.5*6 = 33% meaning the car is worth 67% of what it was originally worth

First do 700 / 100 to find what the car is equal to when it's 1% which is 7, after than multiply its new value of 67%,

so 7*67 = £469

Answer:

$469

Step-by-step explanation:

To find the amount of money that the car loses in value every year, multiply the price of the car by the rate its value depreciates at in decimal form.

The car depreciates at a rate of 5.5% per year. To find 5.5% in decimal form, move the decimal point to left twice. So, 5.5% in decimal form is 0.055.

700 * 0.055 = 38.5

The car loses $38.50 in value every year, so the car's value will depreciate by 6 times that amount in 6 years.

$38.50 * 6 = $231, so the car will lose $231 in value after 6 years.

700 - 231 = 469

The car will be worth $469 in 6 years.

5. The table below represents a quadratic function: draw a graph plot points

What would be the axis of symmetry for the equation?
What is the vertex?
What are the roots?
What is the y-intercept?

Answers

Answer:

The extreme point ( maximum or minimum ) of a parabola is called the vertex, and the axis of symmetry is a vertical line that passes through the vertex. The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function.

Step-by-step explanation:

The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

you have that a = 16 and c = 23, so:

16^2 + b^2 = 23^2

256 + b^2 = 529

b^2 = 273

b = [tex]\sqrt{273}[/tex]
