Answer: (2 1/2, 0) (the last option)
Step-by-step explanation:
I guess the function is:
f(x) = (2 1/2) - (3 1/2)*x
now, the rule for f-1(x) that we know is:
f-1( f(x) ) = x.
So if we want to find the x-intercept of f-1(x), we must evaluate it in f(0)
f-1(f(0)) = 0.
And we have that f(0) = (2 1/2) - (3 1/3)*x = 2 1/2
This means that the x-intercept of f-1(x) will be when x= 2 1/2, so the intercept is:
(2 1/2, 0)

What vector points from the origin to the point (3, -2, 3)?
PLEASE PLEASE HELP
Answers
Answer:
The vector [tex]\vec v = (3,-2,3)[/tex] points from the origin to the point (3,-2,-3).
Step-by-step explanation:
Geometrically speaking, a vector is the change between a final point and a initial point. Since vector are located in space, the origin is represented by point (0, 0, 0) That is:
[tex]\vec v = (3,-2,3)-(0,0,0)[/tex]
[tex]\vec v = (3-0,-2-0,3-0)[/tex]
[tex]\vec v = (3,-2,3)[/tex]
The vector [tex]\vec v = (3,-2,3)[/tex] points from the origin to the point (3,-2,-3).
To solve the problem we must know about Vector points.
PointA point is a position in space. It is represented by a dot.
VectorA vector is something that has both magnitude and direction but no fixed position in space. it is represented by an arrow pointing in a particular direction.
Vector pointsWhen we draw vectors, we attach them to specific points, but we should remember that the vector has no fixed position. These points are known as vector points.
The vector will point toward the point (3, -2, 3) in space.
Given to usvector points = (3, -2, 3)Origin, (0, 0, 0)SolutionAs we know a vector has no fixed position in space, but it points towards its final condition starting from the initial condition. Therefore, its tail is towards the initial condition while its arrowhead is towards the final condition. Thus,
Vector calculationFinal condition - Initial Condition
= (3, -2, 3) - (0, 0, 0)
= (3-0, -2-0, 3-0)
= (3, -2, 3)
Hence, the vector will point toward the point (3, -2, 3) in space.

How many combinations are possible on a 4 number computer cable lock. each space can be any number 0-9 . The only exception is that all four numbers cannot be the same. How many combinations are possible ?
Answers
Answer:
5040
Step-by-step explanation:
Given
Digits: 0 - 9
Required
Number of combinations of 4 digits where no repetition is allowed
First, we need to count the number of digits
[tex]Number = 10[/tex]
Then, we perform the following analysis.
The first space can contain any of the 10 digits;
The second space can contain any of the remaining 9 digits;
The third space can contain any of the remaining 8 digits;
The fourth space can contain any of the 7 digits;
Hence; the umber of combination is
[tex]Number = 10 * 9 * 8 * 7[/tex]
[tex]Number = 5040[/tex]
Hence, there are 5040 possible combinations
What is equation of a line that is parallel to the line y=5x+8 and passes through the point (1,-3)
Answers
Answer:
The answer is
[tex]y = 5x - 8[/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line.
From the question , the original line is
y = 5x + 8
Comparing with the general equation above
Slope / m = 5
Since the lines are parallel their slope are also the same
Slope of parallel line = 5
Equation of the line using point (1,-3) and slope 5 is
[tex]y + 3 = 5(x - 1) \\ y + 3 = 5x - 5 \\ y = 5x - 5 - 3[/tex]We have the final answer as
[tex]y = 5x - 8[/tex]Hope this helps you

company a operates stores under multiple banners in 34 states in the us a. how many states do not have a store operated by company a? b. what fraction of states do not have a store operated by company a?
Answers
Answers: 16 states and [tex]\frac{16}{50}[/tex]
Explanation:
Question A involves finding the number of states that do not have a store operated by company A. This can be easily found by subtracting the number of states where the company operates stores, which is 34 states, from the total of states, which is 50.
50 - 34 = 16
This means 16 states do not have a store operated by this company
Question B involves writing a fraction to represent the number of states that do not have a store operated by the company. A fraction includes a numerator (top number) that represents the parts selected (number of states without a store: 16), and a denominator, which is the total of parts (total of states: 50). Thus, the fraction is [tex]\frac{16}{50}[/tex]. Moreover, this can be simplified as [tex]\frac{8}{25}[/tex] by dividing both numbers by the seame number (2).

Answers
They each have two chocolates so those numbers of chocolates are the same.
Not counting the tubs, Arthur has one bag of chocolates and 25 loose chocolates; Oliver has two bags and 7 loose. If they both have the same total number of chocolates, then the difference in the number of loose chocolates they have (25-7=18) must be the number of chocolates in a bag.
There is no information given, in the problem as you show it, that allows us to determine the number of chocolates in a tub.

Answer: Carpet required: 35 square yards. Cost: $700.
Wallpaper required 185 square feet, 4.2 double rolls needed, but you must buy full rolls. So 5 rolls will cost $125.
Step-by-step explanation:
Multiply the dimensions of the floor to get total square footage. Divide by 9 to convert to square yards.
314.5 ÷ 9 = 34.944. Round to 35 square yards. Multiply by $20 to get the cost of the carpet.
Multiply the dimensions of the wall to get total square footage.
Divide by 44 to get the number of rolls needed. Partial rolls not allowed. So it's 5 rolls times the $25 per "double roll." $125 is the cost.
How many places after the decimal point does the equivalent decimal have if: a. the denominator of the fraction is 10 b. the denominator of the fraction is 100? Look at your answers to problem 4. Explain the reasoning you used to find the answers.
Answers
Answer:I think A is the answer sorry if I’m wrong
Step-by-step explanation:
The equivalent decimal have 1 places right after the decimal point, if
the denominator of the fraction is 10.
And, The equivalent decimal have 2 places right after the decimal point, if
the denominator of the fraction is 100.
Here,
We have to determine places after the decimal point does the equivalent decimal have,
The denominator of the fraction is 10 and the denominator of the fraction is 100.
What is Decimal representation?
A decimal number is a number where the integer part is separated from the fractional part with the help of a decimal point.
Now,
Let the number 2 in numerator,
Denominator = 10
Then, Fraction = 2/10 = 0.2
Hence, The equivalent decimal have 1 places right after the decimal point.
Let the number 3 in numerator,
Denominator = 100
Then, Fraction = 3/100 = 0.03
Hence, The equivalent decimal have 2 places right after the decimal point.
So, The equivalent decimal have 1 places right after the decimal point, if
the denominator of the fraction is 10.
And, The equivalent decimal have 2 places right after the decimal point, if
the denominator of the fraction is 100.
