Answer:
There's no question.
Step-by-step explanation:
Can someone tell me what Pythagorean theorem is? I really need help.
Answer:
The sum of the squares of the two sides equals the square of the hypotenuse (a² + b² = c²).
Let's say you have a triangle with a 90º angle (also known as a right angle). The two equal legs are a and b while the hypotenuse is the longer side. Hypotenuse is and always will be c.
Here's a problem:
c ⊿ a (12)
b (6)
C is missing, we have to find C, so here's what we do:
Step 1: You square all the numbers in the equation
12² + 6² = c²
↓
144 + 36 = c
Step 2: You add 144 + 36 and you get 180
Step 3: Then you find the square root >> [tex]\sqrt{180\\[/tex] and you get ≈13.4
Now sometimes, the a or b would be missing, for example:
c (13)⊿ a
b (5)
A is missing (when a or b is missing, use the following formula, do not use the same formula when c is missing)
Step 1: You square all the numbers in the equation
a² + 5² = 13²
a + 25 = 169
For this next part, you must subtract a or b (in this case, b) on both sides, for example:
25 – 25 = 169 - 25
25 – 25 cancels itself out so now we subtract 169 by 25 and we get 144.
Then we find the square root of 144 and we get 12
I hope this helps :)

Answer:
In about 2018, we will have the population at 30 million
Step-by-step explanation:
Here, we want to get the year in which the population of Texas will reach 30 million
What we have to do here is to substitute f(x) for 30; then get the value of x at this point
We proceed as follows;
30 = 21(1.02)^x
30/21 = 1.02^x
1.42857 = 1.02^x
ln 1. 148257 = ln 1.02^x
ln 1.148257 = x ln 1.02
ln 1.42857/ln 1.02 = x
x = 18 approximately
Adding this to the initial 2000, we have 2018

Answer:
II) 78
Step-by-step explanation:
2x - 6 + 7x + 15 = 90
9x + 9 = 90
9x = 81
x = 9
<ABC:
7x + 15
7(9) + 15
78
Answer and Step-by-step explanation:
To find the measure of angle ABC, we need to find what x is first. We accomplish this by adding together the two angles and setting it equal to 90.
2x - 6 + 7x + 15 = 90
Combine like terms.
9x + 9 = 90
Subtract 9 from both sides.
9x = 81
Divide both sides by 9.
x = 9
We get x to be 9.
Now, we can plug this in for angle ABC.
7(9) + 15
Multiply 7 and 9 together.
63 + 15
Add 63 and 15 together.
78
The measure of ABC is 78.
That means the answer is II) 78.

In triangle ABC, a = 3, b = 5, and c = 7. Find the measure of B.
158°
142°
38°
22°
Answer:
C
Step-by-step explanation:
Since we are given three sides and we want to find an angle, we can use the law of cosines.
The law of cosines is given by:
[tex]b^2=a^2+c^2-2ac\cos(B)[/tex]
In this case, a = 3, b = 5, and c = 7. Therefore:
[tex](5)^2=(3)^2+(7)^2-2(3)(7)\cos(B)[/tex]
Evaluate:
[tex]25=58-42\cos(B)[/tex]
Therefore:
[tex]-42\cos(B)=-33[/tex]
Dividing both sides:
[tex]\displaystyle \cos(B)=\frac{33}{42}[/tex]
And by taking the inverse cosine of both sides:
[tex]\displaystyle \angle B=\cos^{-1}\Big(\frac{33}{42}\Big)=38.2132...\approx 38^\circ[/tex]
Our answer is C.
Answer:
38°

Joe buys 6 adult tickets and 4 child tickets for the movies. Each adult ticket cost $9. Each child ticket cost the same amount. Joe pays with a $100 bill and gets $22 in change. How much does each child ticket cost?
Answer:
Each child ticket cost = $6
Step-by-step explanation:
Joe has = $100
His balance after tickets purchase = $22
Actual amount spent on tickets = $100 - $22 = $78
But,
Each adult ticket cost = $9
Total no of adult = 6
Total amount spent (adults) = $9 x 6 = $54
Balance remaining = $78 - $54 = $24
Amount spent of 4 child tickets = $24
No of children = 4
Therefore,
Amount spent on 1 child (1 ticket),
= $24/4 = $6.
It could be seen that each child ticket cost six dollars.

2. Find the unit rate demonstrated in the graph
below.
A. 9 miles per hour
B. 4.5 miles per hour
C. 3 miles per hour
D. 1.5 miles per hour
The unit rate of demonstrated in the graph will be 4.5 miles per hour. Then the correct option is B.
What is the rate?The rate is the proportion of how much something is to the unit. For instance - Assuming that the speed of the vehicle is 20 km/h it implies the vehicle voyages 20 km in 60 minutes.
The incline is the proportion of rising or falling and running. The contrast between the ordinate is called rise or fall and the distinction between the abscissa is called run.
The slope of the line is given as,
m = (y₂ - y₁) / (x₂ - x₁)
From the graph, take two points from the graph which are (0, 0) and (27, 6).
Then the unit rate demonstrated in the graph will be given as,
Rate = (27 - 0) / (6 - 0)
Rate = 27 / 6
Rate = 4.5 miles per hour
The unit rate of demonstrated in the graph will be 4.5 miles per hour. Then the correct option is B.

Answer:
1) [tex]9^{2}=81[/tex]
2) [tex]7=log_{2}(128)[/tex]
Step-by-step explanation:
1)
We need to use the property of power and logarithms, particularly this:
[tex]a=x^{log_{x}(a)}[/tex] (1)
So, let's take take the exponent:
[tex]9^{log_{9}}(\frac{1}{81})=9^{-2}[/tex]
[tex]\frac{1}{81}=9^{-2}[/tex]
now, we can write the negavitve power as:
[tex]\frac{1}{81}=\frac{1}{9^{2}}[/tex]
So, the aswer will be:
[tex]9^{2}=81[/tex]
2)
Applying equation 1, let's take log in base 2 on each side of the equation
[tex]log_{2}(2^{7})=log_{2}(128)[/tex]
using the power definition in log, we have:
[tex]7log_{2}(2)=log_{2}(128)[/tex]
Therefore, the answer is:
[tex]7=log_{2}(128)[/tex]

Answer:
Average rate of change = 1
Step-by-step explanation:
Average rate of change of a function between x = a and x = b is defined by,
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
We have to find the average rate of change of the function in the interval 2 ≤ x ≤ 4
Therefore, average rate of change of the function = [tex]\frac{f(4) - f(2)}{4-2}[/tex]
From the graph attached,
f(4) = 4
f(2) = 2
Average rate of change = [tex]\frac{4-2}{4-2}[/tex]
= 1
Therefore, average rate of change of the function in the given interval is 1.
