What is the slope of the line that passes through (2, -3) and (9. -7)? Fractions must be in simplest form.
Answer:
-4/7
Step-by-step explanation:
(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 ?
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]

write an equation in slope- intercept form of each line
Answer:
Use the slope −2 and the point (−4,−5) to find the y-intercept.
y=mx+b
⇒−5=(−2×−4)+b
⇒−5=8+b
⇒b=−13
Write the equation in slope intercept form as:
y=mx+b
⇒y=(−2)x−13
Hence, the equation of the line is y=−2x−13.
Given the triangle: A=34.5°, B=81.4°, and a=42.8cm, solve for side b
Answer:
b = 100.9 cm
Step-by-step explanation:
a / A = 42.8 / 34.5 = 1.24
B x 1.24 = b
81.4 x 1.24 = 100.9

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.

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.
