A 25-foot wire connects the top of a utility pole to a point on the ground located 7 feet away from the base of the pole.



If h represents the height of the pole, what is its measure?

A. 175 ft.
B. 24 ft.
C. 674 ft.
D. 1250 ft.

Answers

Answer 1

Answer:

The answer is D

Step-by-step explanation:

Answer 2

The measure of the height of the pole (h) will be;

⇒ h = 24 ft.

What is Pythagoras theorem?

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

We have to given that;

The length of the wire which connects the top of a utility pole to a point on the ground = 25 foot

And, A point on the ground located 7 feet away from the base of the pole.

Now,

Let the height of the pole = h

So, We can apply the Pythagoras theorem as;

⇒ 25² = h² + 7²

⇒ 625 = h² + 49

⇒ h² = 625 - 49

⇒ h² = 576

⇒ h = √576

⇒ h = 24 ft.

Thus, The height of the pole = 24 ft.

How much time required to complete a10days work if it could complete by 3 worker in 4days and 6worker in 3.05 days,if 5 workers is involved in it? please reply​

Answers

Answer:

This seems to be a linear relationship:

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

We know that 3 workers can complete the job in  4 days.

Then if we define W as the rate at which a single worker can complete the work, we have the ordered pair (3 workes, 4 days)

And we also know that 6 workers can finish the job in 3.05 days, then we also have the ordered pair (6 workers, 3.05 days)

Then using these two, we can find the slope of the line:

a = (3.05 days - 4 days)/(6 workers - 3 workers) = -0.35 days/worker.

Then we have the equation:

y = (-0.35 days/worker)*x + b

Where:

y represents the time to complete the job

x represents the number of workers.

b is the y-intercept, to find the value, we could just replace one of the points in the equation, for example with the point (3 workes, 4 days) we need to replace x by 3 workers, and y by 4 days:

4 days = (-0.35 days/worker)*3 workers + b

4 days = -1.4 days + b

4 days + 1.4 days = 5.4 days  = b

then the equation is:

y = (-0.35 days/workers)*x + 5.4 days.

Now we can find the number of days needed for 5 workers to finish the job, we just need to replace x by 5 workers:

y = (-0.35 days/workers)*5 workers + 5.4 days

y = 3.65 days.

Factor the equation

Answers

Answer:

y = (x + 4)²

Step-by-step explanation:

Given equation is,

y = x²+ 8x + 16

By using identity (a + b)² = a² + 2ab + b²

y = x² + 2(4)(x) + 4²

Here a = x and b = 4

y = (x + 4)²  

Therefore, factored form of the given equation is y = (x + 4)²

Answers

Answer:

5x3+9x2+15x+27

Step-by-step explanation:

The expression that is equivalent to (mn)(x) is 5x³ + 9x² + 15x + 27.

Option A is the correct answer.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example: so

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To find the product of m(x) and n(x), we need to multiply the two polynomials term by term:

m(x) = x² + 3

n(x) = 5x + 9

mn(x) = (x² + 3) (5x + 9)

Multiplying the two polynomials using the distributive property.

mn(x) = 5x³ + 9x² + 15x + 27

Thus,

The expression that is equivalent to (mn)(x) is 5x³ + 9x² + 15x + 27.
