(someone please answer these. im literally not turning in my test until someone does. ) 1 a ladder is leaning agisnt a building so that the top of the ladder is touching the roof line. the bottom of the ladder is 8 feet from thr building and thr ladder is 17 feet long. how far is the roof line from the ground 15 ft, 9ft 18.8 ft 25ft

2 what is the value of x ?

Answers

Answer 1

Answer:

1. 15ft

2. 12

Step-by-step explanation:

1. See the attachment below showing the right triangle formed by the ladder and the building.

Let x represent how far the roof line is from the ground.

Thus, using Pythagorean Theorem, x can be solved as follows:

x² = 17² - 8²

x² = 225

x = √225

x = 15ft

2. Given:

Reference angle = 45°

x = Hyp

6√2 = opposite

Using trigonometric ratios formula, thus:

[tex] sin(45) = \frac{6\sqrt{2}}{x} [/tex]

Multiply both sides by x

[tex] sin(45)*x = 6\sqrt{2} [/tex]

Divide both sides by sin(45)

[tex] x = \frac{6\sqrt{2}}{sin(45)} [/tex]

[tex] x = \frac{6\sqrt{2}}{\frac{1}{\sqrt{2}}} [/tex] (common value of sin(45) = 1/√2)

[tex] x = 6\sqrt{2} \times \frac{\sqrt{2}}{1} [/tex]

[tex] x = 6\sqrt{2 \times 2} [/tex]

[tex] x = 6 \times 2 [/tex]

[tex] x = 12 [/tex]

if f (x) = 3, what is the value of f (-7)

A. x -10
B. 3
C. -4
D. -21

Answers

Answer:

Step-by-step explanation:

3*(-7)=(-21)

A constant function is a function that has the same output with different inputs.

The value of f(-7) for the function f(x) = 3 is 3.

What is a constant function?

A constant function is a function that has the same output with different inputs.

It is a function having the same value of range for different values of the domain.

Example: f(x) = 9

f(1) = 0

f(2) = 6

Domain = inputs = 1, 2

Range = outputs = 9

We have,

f(x) = 3

This is a constant function.

So any value of x will always give the output as 3.

f(-7) = 3.

Thus the value of f(-7) for the function f(x) = 3 is 3.

Jennifer did not pay her credit card bill in full in September. Her October
bill showed a finance charge, and she wants to see whether it is correct or
not. The average daily balance is $970.50, and the APR is 15,6%. Find
the finance charge for her October statement.

Answers

Answer: $12.6165

Step-by-step explanation:

Finance charge = Average daily balance × monthly periodic rate.

where,

Monthly periodic rate = APR / 12 months

Monthly periodic rate = 15.6% / 12

= 0.156 / 12

= 0.013

Finance charge = $970.50 × 0.013

= $12.6165

How far is 75% of a 2000 km trip

Answers

Answer:

1500

Step-by-step explanation:

75% of a 2000 km trip is 1500.

What is meant by Percentage?

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

Percentage is usually denoted by the symbol '%'.

Given,

Total distance = 2000 km

We have to find the 75% of the given distance.

Let x be the 75% of the required distance.

x = 75% × 2000

x = (75/100) × 2000

x = 0.75 × 2000

x = 1500

Hence the 75% of the given distance is 1500 km.
