Answer:
Step-by-step explanation:
we have a right triangle,
to find out the hypotenuse, h
H^2=13^2+4^2
H^2=169+8=177
The required equation would be x² = 13² + 4² which is determined by Pythagoras theorem that is used to the length of the Ladder needed to reach the window.
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
What is Pythagoras theorem?Pythagoras theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
We have given that the window is 13ft above the ground and the base of the ladder is 4ft from the building
As per the condition, We have a right triangle.
To find out the hypotenuse x
By Pythagoras theorem,
⇒ x² = 13² + 4²
⇒ x² = 169 + 8
Therefore, the equation would be x² = 13² + 4²which is used to determine the length of the Ladder needed to reach the window.
Hence, the correct answer would be an option (A).

FIND M∠R (GIVING BRAINLIEST, 25 PTS)
Answer:
76Step-by-step explanation:
to understand thisyou need to know about:trianglesequationPEMDASgiven:[tex]M\angle T=2x+2[/tex][tex]M\angle R=3x+1[/tex]tips and formulas:this is an isosceles triangle since two sides are equal therefore [tex]\angle T=\angle S[/tex]a triangle contains 180°let's solve:according to the question
2x+2+2x+2+3x+1=180
solve:
collect like terms:7x+5=180substract 5 from both sides:=>7x+5-5=180-5=>7x=175divide both sides by 7: =>7x/7=175/7x=25given:
M∠R=3x+1
substitute the value of x
3×25+1
75+1
76
Answer:
M∠R=76°
Step-by-step explanation:
First, I realized that ∠S was equal to ∠T, meaning ∠S=2x+2. I then added all 3 angles together and set them equal to 180, seeing the angles of a triangle must add up to 180 (2x+2+2x+2+3x+1=7x+5=180)
After that, I subtracted 5 from 180 and then divided by 7 to get x=25. I then solved the equation 3x+1 by plugging 25 in for x and ended up with 76 as my final answer.
what is the domain of the function a^x
Answer:
The domain of a function is the complete set of possible values of the independent variable. In plain English, this definition means: The domain is the set of all possible x-values which will make the function "work", and will output real y-values.
Step-by-step explanation:
Answer:
The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.
Step-by-step explanation:
Identify the input values.
Since there is an even root, exclude any real numbers that result in a negative number in the radicand. ...
The solution(s) are the domain of the function.
-. A scale model of an oil tanker truck can hold 1 gallon of oil. If a trucking company wants the full size-truck to hold 8,000 gallons of oil, what scale factor must they apply to the model.
Answer: 8,000
Step-by-step explanation:
If the scale model can only hold 1 gallon of oil but the full size truck needs to hold 8,000 gallons, you can find a relevant scale factor using cross multiplication:
1 : 1
x : 8,000
x = 8,000
They should apply a scale factor of 8,000.
The scale factor that they must apply to the model is 1 is to 8000.
How to calculate scale factor:A scale factor of a given quality is what is multiplies the quantity to give a total.
The original content of the oil tanker truck is 1 gallon
The new full size truck is to hold 8000 gallons
That is 1 × 8000 of the old oil tanker truck.
Therefore, the scale factor that they must apply to the model is 1 is to 8000.

find the length of the third side of the right triangle!!!!
Answer:
8
Step-by-step explanation:
There are two ways to solve this!
1. Use the Pythagorean Theorem
a^2 + b^2 = c^2
6^2 + b^2 = 10^2
100 - 36 = b^2
64 = b^2
8 = b
2. Shortcut using 3-4-5 triangles
A 3-4-5 triangle has to do with the ratios of each side.
In this case, it's 6-8-10, as each number is multiplied by two with the same 3-4-5 ratio. This is a good shortcut for these types of problems and will be handy on tests like the SAT as well! :)

3x-4y=16 slope and intercept form
Answer:
y=3/4x-4
Step-by-step explanation:
The form is y=mx+b so isolate y
-4y=16-3x
y=-16/4-3x/-4
y=3/4x-4
Answer:
y = 3/4x - 4
Step-by-step explanation:
Slope intercept form: y = mx + b
3x - 4y= 16
-4y = 16 - 3x
4y = -16 + 3x
y = -4 + 3/4x
y = 3/4x - 4

At the World Cup, 25% of the teams are from South American countries. If there are 40 teams in the World Cup, how many are from South American countries? Construct a double number line if needed.
Answer:
10
Step-by-step explanation:
100% = 40 teams
1% = 40 ÷ 100 = 0.40
25% = 0.40 x 25 = 10
Answer:
10
Step-by-step explanation:
100%/4=25%
40/4=10
You have to divide 100% by 4 because 25 goes into 100 four times.
What ever you do on the bottom or top you to do it top or bottom.
So 40 divide by 4 is 10.
Then you have you answer.

Problem: A pole is being held up with a 10 meter rope. The cable is making a 42° of elevation from the ground to
the top of the pole. What is the distance from the base of the pole to the base of the rope ? Round your answer
to the nearest tenth of a meter.
Answer:
x = 7.4
Step-by-step explanation:
cos(42°) = x/10 or distance from bases / rope length
Using the calculator find the value of cos(42°):
cos(42°) = 0.74 = x/10
Find x using the value of cos(42°):
x/10 = 0.74
x = 7.4

When you have an x value of zero in a point like this one (0,8) where is the point located on the graph? When you have a y value of zero in a point like this ( -3,0) where is the point located on the graph?
plz explain
Answer:
well I don't have a picture to explain it but (0,8) would be on the y axis and 8 on the x-axis ( it would go up 8 times and stay on the same line)
it would be -3 on the y axis and it wouldn't move up or down (move 3 points to the left)
Step-by-step explanation:
(x,y) when the x is 0 it doesn't move on the x-axis (left or right) and when it is 0 it doesn't move on the y-axis (up or down)
hope that makes sense!

Answer:
48/5
Step-by-step explanation:
By power of a point on P, we have PB * PA = PY^2. Therefore,
PB = PY^2/PA = 9^2/15 = 27/5. Then AB = PA - PB = 15 - 27/5 = 48/5
