Answer:
[tex]f^{-1}(x) = \sqrt[3]{x+5}[/tex]
Step-by-step explanation:
A function [tex]f^{-1}[/tex] is the inverse of f if whenever y =f(x) and [tex]x =f^{-1}[/tex]
To find the inverse of f(x) = [tex]x^{3}[/tex] - 5, we use the following steps:
Step 1 : Put y for f(x) and solve for xy = [tex]x^{3}[/tex] - 5
<=> [tex]x^{3}[/tex] = y + 5
<=> x = [tex]\sqrt[3]{y+ 5}[/tex]
Step 2: Put [tex]f^{-1}(y)[/tex] for x, we have:[tex]f^{-1}(y) =\sqrt[3]{y+5}[/tex]
Step 3: Interchange y =x, we have[tex]f^{-1}(x) = \sqrt[3]{x+5}[/tex]
Let Calculate 3 points on f(x)
x = 0 => y = -5
x = 1 => y = -4
x = 2 => y = 3
Let Calculate 3 points on [tex]f^{-1}[/tex] (x)
x = -5 => y = 0
x = -4 => y = 1
x = 3 => y = 2

Answer:
90
Step-by-step explanation:
The formula for a triangle is base times height then dividing it by 2
So 15 times 12 is 180 and dividing it by 2 gets you 90.
Hope this helps!
Answer:
72 :)Step-by-step explanation:
To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.Hope this helps
Your credit card limit is $5,000, and your current balance is $4,500. Your credit score will increase by 10 points for every $250 decrease in your balance. At the end of the year you have paid down your balance to $2,500. By how many points has your credit score increased?
Answer:
80
Step-by-step explanation:
4500-2500 is 2000 dollars reduction, or money paid off.
For every 250 dollars, there is a 10 points increase. 2000 divided by 250 is 8. There are 8 sets of 250 dollars. So, for every 250 dollars (you have 8 of them), 10 points increase. Therefore, you multiply 10 by 8.
10x8 = 80. Your credit score has increased by 80 points.
At the end of the year, my credit score would have increased by 80 points.
If my current balance is $4500 and at the end of the year, my balance is $2500. It means that the total decrease in my credit balance is $2000 ($4500 - $2500).
In order to determine the total increase in the number of points, the first step is to determine the amount of 250 that is in 2000. In order to do this, the first step would be to divide 2000 by 250.
2000 / 250 = 8
The second step is to multiply 8 by 10
8 x 10 = 80 points.

Suppose that an urn contains 3 black marbles, 7 yellow marbles, and 10 green marbles. If one marble is selected, determine the probability that it is green. The answer should be an integer or a simplified fraction.
Answer:
1/2
Step-by-step explanation:
Simple probability is a ratio of the number of ways the thing we want to happen can to the total possible outcomes.
(For example, we flip a coin and want heads, but it can land on heads or tails. Our probability of getting heads is 1/2, one way to get heads over the 2 possible outcomes)
So for this problem, there's 20 possible things that CAN happen (3 + 7 + 10) and 10 ways we get what we want (a green marble).
Our probability of getting a green marble is [tex]\frac{10}{20\\}[/tex], which simplifies to [tex]\frac{1}{2}[/tex]

A blanket is 4 feet wide. It is 3 times as long as it is wide. Find the perimeter and area of the blanket.
Answer:
P: 32
A: 48
Step-by-step explanation:
(4+(4*3))*2=32
4*(4*3)=48
The blanket is 4 feet wide and 12 feet long. The perimeter of the blanket is 32 feet and the area is 48 square feet.
Explanation:The blanket is given to be 4 feet wide, and its length is 3 times its width, which means the length is 3 x 4 = 12 feet. Therefore, the blanket is 4 feet wide and 12 feet long.
For a rectangle, the formula for perimeter is 2*(length + width). Plugging in our values gives us 2*(12 + 4) = 32 feet.
The formula for the area of a rectangle is length * width. Using our dimensions, the area is 12 * 4 = 48 square feet.

Which expression is equivalent to 8g+2+4g-2-2g
Answer:
10g
Step-by-step explanation:
add 8g,4g and -2g to get 10g
add 2 and -2 to receive 0
the simplified expression would be 10g
The equivalent expression for 8g + 2 + 4g - 2 -2g after combining like terms is 10g.
The original expression given is 8g + 2 + 4g - 2 -2g. To find an equivalent expression, we need to combine like terms. We do this by adding or subtracting the coefficients of identical variables and also combining any constant terms.
In this case, we combine the coefficients of g:
8g + 4g - 2g = (8 + 4 - 2)g = 10g.
Next, we combine the constant terms: 2 - 2 = 0. Since adding or subtracting 0 does not change the value, we can ignore this part.
Thus, the equivalent expression is simply 10g.

A bag contains 40 tickets, each numbered between 1-40. If a ticket is drawn at random, find the probability of it being odd or less than 26
Answer:
you have a 50% chance of getting an odd number and a 60% chance of getting a number less than 26.
Step-by-step explanation:
Between 1 and 40 there are 20 odd numbers
20÷ 40 x 100=50, This means you have a 50% (20:20) chance of getting an odd number.
Between 1 and 40 there 25 numbers less than 26
15÷25 x 100=60, This means you have a 60% (25:15) chance of getting a number under 26.
Final answer:
The probability of drawing an odd ticket or a ticket numbered less than 26 from a bag containing 40 numbered tickets is 4/5 or 0.8, meaning there is an 80% chance to draw such a ticket.
Explanation:
To find the probability of drawing an odd ticket or a ticket numbered less than 26 from a bag containing tickets numbered 1-40, we need to consider the total number of favorable outcomes for each separate event and be careful not to double-count any outcomes that satisfy both conditions.
Firstly, there are 20 odd numbered tickets (1, 3, 5, ..., 39) which satisfy the first condition. For the second condition, there are 25 tickets that are numbered less than 26 (1, 2, 3, ..., 25).
However, half of the tickets less than 26 are odd (1, 3, 5, ..., 25), which we've already counted. So, we should only add the even numbered tickets that are less than 26 to get the total number of favorable outcomes. There are 12 even numbered tickets less than 26 (2, 4, 6, ..., 24).
Adding the odd numbered tickets (20) to the unique even numbered tickets less than 26 (12), we get a total of 32 favorable outcomes.
Since there are 40 tickets in total, the probability of drawing a ticket that is either odd or less than 26 is 32/40.
To simplify, divide both numerator and denominator by their greatest common divisor which is 8, giving us 4/5 or 0.8, which means there's an 80% chance of drawing a ticket that meets the criteria.

Ryan and Matt are playing a game by rolling two number cubes, with faces numbered 1 through 6, one after the other. Ryan gets a point when the number on the first cube is an odd number and the number on the second cube is an even number. Matt gets a point when the number on the first cube is 5. The table below shows all possible combinations of numbers on the cubes.
Who is more likely to get a point on the first roll of both the cubes?
A.
Ryan is more likely to get a point, because 13/36>9/36
B.
Matt is more likely to get a point, because 13/36 > 6/36
C.
Both are equally likely to get a point, because 6/36 = 6/36
D.
Ryan is more likely to get a point, because 9/36>6/36
Ryan is more likely to get a point than Matt on the first roll of both cubes.
The fraction of outcomes in which Ryan gets a point is 9/36, which simplifies to 1/4.
The fraction of outcomes in which Matt gets a point is 1/36.
Option A is the correct answer.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
To determine who is more likely to get a point, we need to count the number of outcomes that satisfy each condition and then compare the fractions.
Ryan gets a point if the first cube shows an odd number and the second cube shows an even number.
There are three odd numbers and three even numbers,
So there are 3 x 3 = 9 outcomes that satisfy this condition.
Matt gets a point if the first cube shows a 5.
There is only one outcome that satisfies this condition.
Therefore,
Ryan is more likely to get a point than Matt on the first roll of both cubes.
The fraction of outcomes in which Ryan gets a point is 9/36, which simplifies to 1/4.
The fraction of outcomes in which Matt gets a point is 1/36.
