Given:
A diagram of two triangles.
To find:
Check whether the triangles are similar or not.
Solution:
In triangle ABC and triangle UVT,
[tex]\angle A\cong \angle U[/tex]
[tex]\angle B\cong \angle V[/tex]
Two corresponding angles of the triangles are congruent. So,
[tex]\Delta ABC\sim \Delta UVT[/tex] (AA property of similarity)
Therefore, the given triangles are similar by AA property of similarity.
The calories I burn walking can be modeled by the function y = 5x + 100,
with x representing the number of minutes spent walking. How many
calories would I burn if I walked for 75
minutes?
Answer:
X=75
Y=5X+100
Y=5*75+100
Y=375+100
Y=475
Therefore, you burnt 475 calories if you walked for 75 minutes

The measures of two complementary angles have a ratio of 2:3. What is the measure of the larger angle?
The measure of the larger angle is
°.
Step-by-step explanation:
complementary angles add up to 90
x +2/3x = 90
5/3x = 90
5x = 270
x = 54
the other angle is 36
double checking
54 * 2 ÷ 3 = 36

In the equation 2
2 + 5 is the left side of the equation and 0 is the right side. In this equation only the left side contains the variable, y. In the equation 4 +5=-2x+10,theexpression
4 + 5 is the left side of the equation and - 2 + 10 is the right side. In this equation both sides have expressions that contain the variable, x.
1 Determine Whether a Number Is a Solution to an Equation
An equation in one variable is a statement made up of two expressions that are equal, and in the statement, at least one of the expressions contains the variable. The expres- sions are called the sides of the equation. Examples of equations in one variable are
2y + 5 = 0 4x + 5 = -2x + 10 3 = 9 z+2
In this section, we will concentrate on solving linear equations in one variable.

Find the amplitude and the period of the graphed function; please show work or steps.
Answers:
Amplitude = 2Period = 5pi/2===========================================
Explanation:
The lowest point occurs when y = -2. The highest point occurs when y = 2.
The vertical distance between the highs and lows is 4 units (since 2-(-2) = 2+2 = 4). This cuts in half to get 4/2 = 2.
The amplitude is 2. It measures the vertical distance from the midline to either the peaks or valleys.
-----------------------------
Note that this curve has two lowest points and one highest point shown. What we'll do is shift the graph over to the right so that each of those lowest points snap to a grid point. The lowest point on the left will move to where x = -pi, while the lowest point on the right snaps to x = 3pi/2. We'll keep each point at the same y coordinate.
The horizontal distance from x = -pi to x = 3pi/2 is
(3pi/2) - (-pi) = 3pi/2 + 2pi/2 = 5pi/2
This represents the horizontal distance from the left valley point to the right valley point. This is one full period of the curve. After we arrive at the right valley point, we repeat the process of going up and coming back down in this exact same fashion. The process is repeated forever to generate the cosine curve. The curve repeats itself every 5pi/2 units along the x axis.
Side note: any phase shift of a curve will have the same period as the original curve. This is why we're allowed to shift left or right to help find the period.

A behavioral economist studies transportation habits in an urban center. She identifies 4 bus routes that connect to 3 different light rail routes available to participants in the study. Before she interviews participants, she must determine the number of possible routes participants can choose to use. Which expression represents the number of available options
a. 4!+3!
b. 4×3
c.4!×3!
d. 4!/3!
Answer:
Total possible routes participants can choose = 4×3 = 12 ways
The correct option is - b. 4×3
Step-by-step explanation:
Given - A behavioral economist studies transportation habits in an
urban center. She identifies 4 bus routes that connect to 3
different light rail routes available to participants in the study.
To find - Before she interviews participants, she must determine the
number of possible routes participants can choose to use.
Which expression represents the number of available options.
Proof -
Given that ,
Total bus routes = 4
So, number of possible ways she use the bus route = 4
Also,
The 4 bus route connects to 3 different light rail
So, possible ways that she use light rail = 3
∴ we get
Total possible routes participants can choose = 4×3 = 12 ways
The correct option is - b. 4×3
