Answer:
f^-1(x)=³√[(x+7)÷4]
Step-by-step explanation:
f(x)=4x^3-7
y=4x^3-7
interchange 'y' with 'x'
x=4y^3-7
make y the subject
4y^3=x+7
divide by 4 both sides
y^3=(x+7)÷4
multiply by the cube root both sides
³√(y^3)=³√[(x+7)÷4]
y=³√[(x+7)÷4]
f^-1(x)=³√[(x+7)÷4]
What is the length of DT where D(-6-2) and T(7-8)
Answer:
[tex] d = \sqrt{205} [/tex]
Step-by-step explanation:
[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
[tex] d = \sqrt{(-8 - (-2))^2 + (7 - (-6))^2} [/tex]
[tex] d = \sqrt{(-6)^2 + 13^2} [/tex]

18=3(3x-6) multi step equation
Answer:
x=4
Step-by-step explanation:
18=3(3x-6)
Divide each side by 3
18/3=3/3(3x-6)
6 = 3x-6
Add 6 to each side
6+6 = 3x-6+6
12 = 3x
Divide by 3
12/3 = 3x/3

The variable n represents the number of bikes in a shipping container. The weight of the container in pounds, including the bikes, can be modeled using the expression 250+23(n−1). How much will the container weigh with 20 bikes in it?
Answer:
678
Step-by-step explanation:
250 + 23 (20 - 1 )
Replace the n with 20 Bc n is the number of bikes
250 + 23 (20 - 1 )
Do the parentheses
250 + 23 (19)
Multiply the 23 by 19
250 + 437
Add both numbers
The required weight of the 20 bikes in the container is 687 pounds.
An expression regarding relative weight between the bike-containing container is given 250+23(n−1), where n represents the number of bikes and the whole equation gives the cumulative weight of the bikes.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The given expression is 250+23(n−1),
Now, put n = 20 According to the question,
Wight = 250 + 23 (20 - 1)
Weight = 250 + 23 * 19
Weight = 687.
Thus, the required weight of the 20 bikes in the container is 687 pounds.

what is the answer to 2x+4x=x+3?
Answer:
x=3/5
Step-by-step explanation:
2x+4x=x+3
6x=x+3
5x=3
x=3/5
Answer: [tex]x=3/5[/tex]
Simplify both sides of the equation
[tex](2x+4x)=x+3[/tex] (Combine Like Terms)
[tex]6x=x+3[/tex]
Subtract x from both sides
[tex]6x-x=x+3-x\\5x=3[/tex]
Divide both sides by 5
[tex]5x/5=3/5\\x=3/5[/tex]

I need to find f(-2) in this graph however I don't know please help me
======================================================
Explanation:
Check out the diagram below. Locate -2 on the horizontal x axis. Draw a vertical line through this value. Mark where the vertical line crosses the curve. Call this point P. Then draw a horizontal line through point P to have it cross the y axis. This horizontal line crosses at y = 1
In short, x = -2 leads to y = 1
So that is why f(-2) = 1
This is another way of saying f(x) = 1 when x = -2.
Note: y = f(x) since both are outputs of a function

A basketball player makes 60% of his free throws. We set him on the line of free-throw and informed him to shoot free throws until he misses. Let the random variable X be the number of free throws taken by the player until he misses. Assuming that his shots are independent, find the probability that he will miss the shot on his 6th throw. Show work detail please
a) 0.04666
b) 0.03110
c) 0.01866
d) 0.00614
Answer:
B. 0.03110
Step-by-step explanation:
Given
Probability of Hit = 60%
Required
Determine the probability that he misses at 6th throw
Represent Probability of Hit with P
[tex]P = 60\%[/tex]
Convert to decimal
[tex]P = 0,6[/tex]
Next; Determine the Probability of Miss (q)
Opposite probabilities add up to 1;
So,
[tex]p + q = 1[/tex]
[tex]q = 1 - p[/tex]
Substitute 0.6 for p
[tex]q = 1 - 0.6[/tex]
[tex]q = 0.4[/tex]
Next,is to determine the required probability;
Since, he's expected to miss the 6th throw, the probability is:
[tex]Probability = p^5 * q[/tex]
[tex]Probability = 0.6^5 * 0.4[/tex]
[tex]Probability = 0.031104[/tex]
Hence;
Option B answers the question

b) 0.03110

Jacob needs 48 ounces of tomatoes for the spaghetti sauce he is choosing between the two brands shown explain how Jacob can determine which is the better value
Answer:Jacob could compare the unit rates of cost per ounce. The unit rate that is less per ounce is the better deal. Not He can look at the cost per ounces!
Im late but hope this helps anyone doing makeup work!
Brand A costs $0.37 or 37 cents per ounce and Brand B costs $0.31 or 31 cents per ounce.
We need to find the unit rate for each brand. Round to the nearest cent (hundredth).
What are ounces?The definition of an ounce is 1/16 of a pound or a very small amount of something.
According to column 1, 8 ounces of tomatoes would cost 2 dollars and 99 cents. So, the cost of one ounce of tomatoes can be calculated as follows.
When the cost of one ounce of tomatoes is rounded off to the nearest cent, it can be written as $0.37.
According to column 2, 16 ounces of tomatoes would cost 4 dollars and 99 cents. So, the cost of one ounce of tomatoes can be calculated as follows.
When the cost of one ounce of tomatoes is rounded off to the nearest cent, it can be written as $0.31.
Therefore, Brand A costs $0.37 or 37 cents per ounce and Brand B costs $0.31 or 31 cents per ounce.
