Hi there!
[tex]\large\boxed{y = f(x) = log_{2}x}[/tex]
We can go through each given function and determine whether the graph is its representation:
y = f(x) = log₂x. The graph pictured is logarithmic as it contains a vertical asymptote (discontinuity) at x = 0.
y = f(x) = x². This equation contains a parabolic shape. This is incorrect.
y = f(x) = 2ˣ. This equation is an exponential, increasing function. This is incorrect.
Another way to check would be to use the point on the graph (1, 0), and plug the corresponding x and y values into each function.
For example:
0 = log₂(1) is correct.
0 = (1)² is incorrect.
0 = 2¹ is incorrect.
Answer:
The answer is y=f(x) = log2x

took the test and got it right hope you guys do well !!
Can u find the value of the x.
Answer:x=8
Step-by-step explanation:
x²-3x=-3x+64
- Add 3x to both sides
x²-3x+3x=-3x+3x+64
= x²=64
- Square both sides
√x²=√64
x=±8
- Since the question is asking for the positive value of x, the answer is 8.

Which number is an integer?
Answer:
Step-by-step explanation:
Can you please specify on that question
Answer:
Integers are numbers that include the negatives, zero and positives.
Step-by-step explanation:
If you ever get confused there's a big circle chart to help you remember look for it online!! What I use to remember is visualizing a number line!
First is the real numbers, so the numbers we were taught since we were little like 1, 2 ,3, 4, 5, 6 and so on. So that's the first part of the number line.
Next is the whole numbers so you just add a zero to that number line. Whole numbers is just all of the real numbers + the number zero.
Then it's the integers so you add the left side of that number line. Integers are real numbers, whole numbers, and negatives. So basically on the number line it's the negatives , zero, and the positives.
Last it's the radicals so all parts of a number like fractions and decimals. So you can add .5 in between the numbers of that numberline.
I hope this strategy helped and if it didn't here's that circle chart!!
I really hope this did help tho!!
christen has to run around the rectangle soccer field during practice. The soccer field measures 60 meters long by 45 meters wide. How far did christen run?
Answer:
210 m
Step-by-step explanation:
Perimeter is the distance around the outside of a two-dimensional shape.
Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.
Christen ran around the soccer field, so she ran around the perimeter.
We can find the perimeter by adding all of the side lengths.
Perimeter=60 m+45 m+60 m+45 m
Christen ran 210m.

evaluate 9P4
A. 9
B. 362,880
C. 126
D. 3024
Answer:
3024
Step-by-step explanation:
3024
Option (D) 3024 is the permutation value is the correct answer.
What is a permutation?A permutation is an arrangement of objects in a definite order. It is a number of ways a particular set can be arranged, where the order of the arrangement matters.
For the given situation,
The value of 9P4
The formula to find permutation is
[tex]nP_{r}=\frac{n!}{(n-r)!}[/tex]
Here, n = 9 and r = 4
⇒ [tex]9P_{4}=\frac{9!}{(9-4)!}[/tex]
⇒ [tex]\frac{9!}{5!}[/tex]
⇒ [tex]\frac{5!(6)(7)(8)(9)}{5!}[/tex]
⇒ [tex](6)(7)(8)(9)[/tex]
⇒ [tex]3024[/tex]
Hence we can conclude that option (D) 3024 is the permutation value is the correct answer.

Rafa went to Lone Star Auto who charges $35 for each car plus $7 per hour. If Rafa's bill was $63, how many hours did he get his car worked on?
Answer: 4 hours
Step-by-step explanation:
Given
Auto charge a fixed amount of $35
and $7 per hour
Rafa bill was $63
Suppose Rafa travels for x hours. So, we can write
[tex]\Rightarrow 63=35+7x\\\Rightarrow 28=7x\\\Rightarrow x=4\ \text{hour}[/tex]
A tank that holds 6000 gallons of water may be filled by two pipes. One pipe pours water into the tank at the rate of 80 gallons per minute. The other fills the tank at the rate of 120 gallons per minute.
(a) If the pipes run simultaneously, how long will it take to fill the tank?
(b) The small pipe is opened and water is run into the tank for a certain length of time. Then this pipe is shut off and the large one is used to finish filling the tank. How long was each pipe used if it took 60 minutes to fill the tank?
(c) The large pipe alone is opened for a certain time and then both pipes together are used to finish filling the tank. If it takes 34 minutes to fill the tank in this manner, how long was the small pipe used?
Answer:
Below.
Step-by-step explanation:
Working together the rate is 80 + 120 = 200 gallons per minute.
(a) Time to fill tank = 6000 / 200 = 30 minutes.
(b) Let length of time the small pipe was used be x minutes , the the large pipe was used for is 60-x minutes.
Volume delivered by small pipe = y gallons, and by large pipe = 6000-y gallons.
Rate for small pipe = 80 = y/x.
Rate for large pipe = 120 = (6000-y) / 60-x.
y/x = 80
(6000-y) / 60-x = 120
From first equation y = 80x so:
6000 - 80 x = 7200 - 120x
40x = 1200
x = 30
So time for small pipe = 30 and time for large on = 30 minutes also.
C. In a similar way to part B:
y/x = 120
(6000-y) / 34 - x = 200
(6000-120x) / 34 - x = 200
6000 - 120x = 6800 - 200x
80x = 800 so the large pipe on its own took 10 minutes and the small pipe was used for 34 - 10 = 24 minutes.

A triangle has an area of 40 cm². The base and height are scaled by a factor of 4. The area of the resulting triangle is ___ square cm.
Answer:
640 cm ^2
Step-by-step explanation:
40x4x4 = 640
let's say b = 20 and h = 4
1/2(20)(4) = 40
scale by 4
b= 80 h = 16
1/2(80)(16) = 640

What is the length of the hypotenuse of the triangle?
What is the area of this regular pentagon that has been divided into five congruent triangles?
48 [tex]cm^{2}[/tex]
120 [tex]cm^{2}[/tex]
100 [tex]cm^{2}[/tex]
24 [tex]cm^{2}[/tex]
Answer:
120 cm^2.
Step-by-step explanation:
The area of one triangle = 1/2 * base * height
= 1/2 * 8 * 6
= 1/2 * 48
= 24 cm^2
So area of the pentagon = 5 * 24
= 120 cm^2.
