Answer:
B.
Step-by-step explanation:
So, lets remember a few things first.
#1: The formula for finding the answer is A^2+B^2=C^2
#2: A is the opposite side, B is the adjacent side, and C is the hypotenouse side.
Now lets plug in what we already know, and see if we canf igure out the annswer:
A^2+12^2=13^2
Now I am going to stop us here. This is your equation that will find the answer. In your question, they use x^2, A^2 is a variable you can use instead. But looking at this, answer B and my equation I wrote above are exactly the same.
If you want, here is how I further solved it, this might give you a better grasp on what to do for future problems:
Ok, not too bad, the A is the unkown value, which is the opposite side.
Now, how do we figure this out? Well, we just need to sovle for A.
To do this, lets clean up our equation by first sqauring all the values(except for the unkown):
A^2+144=169
Ok, that looks better, now lets just subtract the adjeacent side(b), which is 144, from the hypotenouse side(c), which is 169.
This will now look like:
A^2=25(169-144=25)
Ok, just one more step to go. Just square root both sides of the equation, this way, we will get ride of the ^2 on A(opposite side), and get A alone.
([tex]\sqrt{A^2}=A[/tex])=([tex]\sqrt{25}=5[/tex])
A=5
This is your answer.

[tex]f^{-1}[/tex] (x) = [tex]\frac{x-5}{3}[/tex]
Step-by-step explanation:
let y = f(x) then rearrange making x the subject , that is
y = 3x + 5 ( subtract 5 from both sides )
y - 5 = 3x ( divide both sides by 3 )
[tex]\frac{y-5}{3}[/tex] = x
Change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then
[tex]f^{-1}[/tex] (x) = [tex]\frac{x-5}{3}[/tex]
Alfonso scored 1818 points during his last basketball game, which was 40\%40% of the points the entire team scored. The entire team scored points.
Answers
Answer: 45 points
Step-by-step explanation:
Let the point of the entire team be represented by x.
Alfonso scored 18 points during his last basketball game, which was 40% of the points the entire team scored. This can then be represented in an equation as:
40% of x = 18
40% × x = 18
40/100 × x = 18
0.4 × x = 18
0.4x = 18
x = 18/0.4
x = 45
The team's total point is 45

UVWX is a parallelogram. What is the measure of angle XUV?
Answers
Answer:
We need more info.
Step-by-step explanation:
Even though we need more information to solve this, I can explain how to. if you want me to solve it for you, comment on here and tell me if they gave you any angle measurements. Until then, I'll tell you how.
Look at the attached photo as you read to help you visualize this. Assuming your parallelogram looks roughly like the drawing, you can see that ∠U = ∠W, and ∠X = ∠V. We can determine that because - when working with parallelograms - the angle opposite of the other is always equal. For instance, if the drawing I made is accurate to the one you're looking at, then if ∠U was equal to let's say 120°, then that means that the exact opposite angle, ∠W, would also be equal to 120°.
Offer is still on the table though. If the question gave you any information about any of the degree measures, comment it and I'll solve the problem for you.

Compare the functions shown below:
f(x) = 7x + 3(x) = h(x) 2 sin(3x + π) − 1 Using complete sentences, explain which function has the greatest y-intercept.
Answers
Answer:
f(x) has the greatest y-intercept
Step-by-step explanation:
* Lets explain how to solve the problem
- The function f(x) = 7x + 3
- The function g(x) is tangent function with y-intercept at (0 , 2)
- h(x) = 2 sin(3x + π) - 1
* Lets explain how to find the y-intercept
- The y-intercept means the intersection of the graph of the
function with the y- axis
- Any point on the y-axis has x-coordinate = 0, so to find the y-intercept
of any function substitute x in the function by zero
∵ f(x) = 7x + 3
∵ x = 0
∴ f(x) = 3
∴ The y-intercept of f(x) is 3
∵ g(x) has y-intercept at point (0 , 2)
∴ The y-intercept of g(x) is 2
∵ h(x) = 2 sin(3x + π) - 1
∵ x = 0
∴ h(x) = 2 sin(3 × 0 + π) - 1
∴ h(x) = 2 sin(π) - 1
∵ sin(π) = 0
∴ h(x) = 2 (0) - 1 = 0 - 1 = -1
∴ The y-intercept of h(x) is -1
∵ 3 > 2 and 3 > -1
∴ f(x) has the greatest y-intercept
The function f(x) has the greatest y-intercept i.e. 3.
Given functions are:
[tex]f(x)=7x+3\\[/tex]
[tex]h(x)=2Sin(3x+\pi )-1[/tex]
What is the y-intercept?The y-intercept is the point on the y-axis at which the graph intersects.
We know that on the y-axis, the x-coordinate is zero.
So, by putting x=0 in the function we can get the y-intercept.
1)[tex]f(x)=7x+3\\[/tex]
[tex]f(0)=3[/tex]
So, the y-intercept of f(x) is 3.
2)From the graph we can say the y-intercept of g(x) is 2.
3)[tex]h(x)=2Sin(3x+\pi )-1[/tex]
[tex]h(0)=2Sin\pi -1[/tex]
[tex]h(0)=-1[/tex]
So, the y-intercept of h(x) is -1.
Hence, function f(x) has the greatest y-intercept i.e. 3.

Write an equation for 96% of what number is 24?
Answers
Answer:
0.96 • x = 24, x = 25
Step-by-step explanation:
96% of what number is 24
Let's break this phrase down.
96% can be represented as 96/100 or 0.96
"of" indicates multiplication
"what number" is our unknown variable, x.
"is" represents our equals sign
Then we have our answer 24.
Let's put this all together.
0.96 • x = 24
To solve for this, divide both sides by 0.96.
x = 25

How many liters does that equal?
Answers
Answer:
Either 30 or 32, depending on if your teacher wants you to use exact decimals, or rounded numbers
Step-by-step explanation:
Usually people round liters to equal 4 per gallon, which would give you 32.
However, a liter is technically 3.785 liters per gallon- and this exact number would give you 30 as an awnser.
I'd say 32 is the safer awnser, unless your teacher has given you the number 3.785 decimal amount to use instead.

Answers
Answer:
r/6 +2 = X
Step-by-step explanation:
We want to isolate X by itself to find its value. First transpose your -4 to the other side (note that -4 will become positive)
r + 2 +4 = 3x
r + 6 = 3x
To find the X, we get rid of the 3, so divide both sides by 3
r/3 + 6/3 = x
r/3 + 2 = x
OR
(r+6)/3 = x
Both works : )
Answer:
Step-by-step explanation:
We want to solve r + 2 = 3x – 4 for x.
This means isolating x on one side. To do this, first add 4 to both sides, obtaining r + 2 + 4 =3x, or:
r + 6 = 3x
Finally, divide both sides by 3:
r + 6

☛[tex] \underline{ \underline{ \text{question}}}[/tex] : In the given figure , O is the centre of the circle. Two equal chords AB and CD intersect each other at E. Prove that :
i. AE = CE
ii. BE = DE
*Random/irrelevant answers will not be tolerated !
Answers
Answer:
See Below.
Step-by-step explanation:
In the given figure, O is the center of the circle. Two equal chords AB and CD intersect each other at E.
We want to prove that I) AE = CE and II) BE = DE
First, we will construct two triangles by constructing segments AD and CB. This is shown in Figure 1.
Recall that congruent chords have congruent arcs. Since chords AB ≅ CD, their respective arcs are also congruent:
[tex]\stackrel{\frown}{AB }\, \cong\, \stackrel{\frown}{CD}[/tex]
Arc AB is the sum of Arcs AD and DB:
[tex]\stackrel{\frown}{AB}=\stackrel{\frown}{AD}+\stackrel{\frown}{DB}[/tex]
Likewise, Arc CD is the sum of Arcs CB and DB. So:
[tex]\stackrel{\frown}{CD}=\stackrel{\frown}{CB}+\stackrel{\frown}{DB}[/tex]
Since Arc AB ≅ Arc CD:
[tex]\stackrel{\frown}{AD}+\stackrel{\frown}{DB}=\stackrel{\frown}{CB}+\stackrel{\frown}{DB}[/tex]
Solve:
[tex]\stackrel{\frown}{AD}\, \cong\,\stackrel{\frown}{CB}[/tex]
The converse tells us that congruent arcs have congruent chords. Thus:
[tex]AD\cong CB[/tex]
Note that both ∠ADC and ∠CBA intercept the same arc Arc AC. Therefore:
[tex]\angle ADC\cong \angle CBA[/tex]
Additionally:
[tex]\angle AED\cong \angle CEB[/tex]
Since they are vertical angles.
Thus:
[tex]\Delta AED\cong \Delta CEB[/tex]
By AAS.
Then by CPCTC:
[tex]AE\cong CE\text{ and } BE\cong DE[/tex]
