f(x)=3^x+1 and g(x) = 2x-4, find f(2) - g(-1)

Answers

Answer 1

Answer:

16

Step-by-step explanation:

3^x +1 = f(X)

2x-4 = g(x)

find f(2)-g(-1)

we substitute in function f(X) by value (2), and in function g(X) by value (-1)

1. 3^x +1 becomes 3^2+1 =9+1=10

2. 2(-1)-4= -2-4=-6

then f(2)-g(-1)

= 10-(-6) =10+6=16

Gross pay is $360, Health insurance is $50.40, Pension deduction is $21.60, Total deductions is $173.85 and net pay is $186.15.

What is gross Earnings?

Gross pay or gross earnings is the amount of money an employer earn before all the tax and other deductions and benefits.

Employee works for 40 hours at a rate of $9.00 per hour.

Gross pay = 40 × 9 = $360

Health insurance = 14% of gross earnings

                             = 14% × 360

                             = 0.14 × 360

                             = $50.40

Pension deduction = 6% of gross earnings

                                = 0.06 × 360

                                = $21.60

Total deductions = $55.00 + $21.80 + $25.05 + $50.40 + $21.60

                            = $173.85

Net pay = Gross earnings - Total deductions

             = $360 - $173.85

             = $186.15

Hence the amount of gross pay is $360, and net pay is $186.15.

The guidelines for a wheelchair ramp suggest that the ratio of the rise to the run be no greater than 1 : 12


A. Which wheelchair ramps follow the guidelines

A. A ramp with a length of 30 feet and a height of 3 feet

B. A ramp with a length of 20 meters and a height of 0.5 meters

C. A ramp with a length of 384 inches and a height of 32 inches

D. A ramp with a length of 1 feet and a height of 12 feet




B. A wheelchair ramp provides access to a building with a front door that is 2.5 feet above the sidewalk. Which best describes the possible length(s) for the ramp that will follow the guidelines.

Let x represent the length (in feet) of the ramp

A. X < 30

B. X > 30

C. X ≥ 30

D. X ≤ 30

Answers

Answer:

Q1. Answer: According to the guidelines, the ratio of the rise (height) to the run (length) of a wheelchair ramp should be no greater than 1:12.

Option A: A ramp with a length of 30 feet and a height of 3 feet. The ratio of the rise to the run is 3/30 = 1/10, which is less than 1:12, so this ramp follows the guidelines.

Option B: A ramp with a length of 20 meters and a height of 0.5 meters. The ratio of the rise to the run is 0.5/20 = 1/40, which is less than 1:12, so this ramp follows the guidelines.

Option C: A ramp with a length of 384 inches and a height of 32 inches. The ratio of the rise to the run is 32/384 = 8/96 = 2/24, which is less than 1:12, so this ramp follows the guidelines.

Option D: A ramp with a length of 1 feet and a height of 12 feet. The ratio of the rise to the run is 12/1 = 12, which is not less than 1:12, so this ramp does not follow the guidelines.

Therefore, the ramps that follow the guidelines are options A, B, and C.

Q2. Answer: The guidelines for a wheelchair ramp suggest that the ratio of the rise (height) to the run (length) of the ramp should be no greater than 1:12. In this case, the rise is 2.5 feet and the run is the length of the ramp (x feet). The ratio of the rise to the run is 2.5/x.

To follow the guidelines, the ratio of the rise to the run should be no greater than 1:12, or 1/12. Therefore, the length of the ramp (x) should be greater than or equal to 2.5/1/12 = 30 feet.

Therefore, the correct answer is C: X ≥ 30.

Perry borrows $150 from his brother to fix his car. His brother doesn't like lending Perry money and so charges him 7% interest per month. a. Write a rule in the "y=..." form that will give the amount of money, y, Perry will owe his brother after n months, assuming that he doesn't make any payments.​

Answers

Answer: Let's say,

y = the amount of money Perry will owe his brother after n months.

x = the principal (the initial amount borrowed) = 150

r = the interest rate per month = 7/100 = 0.07

n = number of months.

We know that Interest on a loan is calculated by multiplying the principal by the interest rate.

Therefore, the interest for n months is (0.07*x)*n

So to find the total amount Perry will owe his brother after n months, we need to add the interest to the principal amount.

y = x + interest

y = x + (r*x)n

y = x(1 + rn)

Therefore, the rule in the "y =..." form that will give the amount of money, y, Perry will owe his brother after n months, assuming that he doesn't make any payments is:

y = 150(1 + 0.07*n)

It's worth noting that this formula can be used to calculate the amount he will owe after any number of months by changing the value of n, and It's assuming he doesn't make any payments, meaning if he makes any payments, the total amount he will owe will change.

Step-by-step explanation:

The slope is found using the slope formula. It works well to choose ordered pairs that only differ by 1 in their x-value.

  m = (y2 -y1)/(x2 -x1)

The y-intercept is the y-value when x=0. If it is not in the table, it can be found from one point and the slope.

  b = y1 -m·x1

__

1) slope = (9 -3)/(2 -1) = 6

  y-intercept = -9 -6(-1) = -3

__

2) slope = (21 -(-1))/(2 -0) = 22/2 = 11

  y-intercept = -1 . . . from table for x=0

__

3) slope = (-9-(-11))/(2-1) = 2

  y-intercept = -11 -(2)(1) = -13

4) slope = (-4 -(-5))/(2 -1) = 1

  y-intercept = -7 -1(-1) = -6

How to graph the equation of a line?

y = - 1/2x + 3

In order to graph the equation of the line:

First, find the value of x when y = 0:

y = - 1/2x + 3 , when y = 0:

0 = - 1/2x + 3

1/2x = 3

x = 3 × 2

x = 6

Also, find the value of y when x = 0:

y = - 1/2x + 3, when x = 0:

y = - 1/2(0) + 3

y = 3

Therefore,  the values to be plotted on our graph are (6, 0) and (0, 3). The image of the graph is attached

The Venn diagram to illustrate this information is given 24 children got plantain and 18 rice and 21 chose beans.Following relation are given below.

What is Venn diagram in math?

A  Venn diagram is a diagrammatic representation of two or more sets.The Venn diagram shows the relationship among sets using circles and the area they cover concerning each other.Venn diagrams are used to visually depict sets, relationships between sets, and operations on sets.

What are the symbols in Venn diagram?

∪ symbol shows Union of two sets. A complete Venn diagram represents the union of two sets. ∩ shows the Intersection of two sets.Intersection represents something that you want to compare and contrast. Where the two circles intersect we would write traits that the two things have in common.

Now

The number of children who took plantain and beans only are:

Let  beans = a

Rice = b

Plantain = P

So:  a + b = 24 - 9 - 5 = 10

Note that 24 children took plantain.

9 children took only Plantain.

5 took the 3 food items.

So,

b + c = 18 -2 - 5 = 11

a + c = 21 - 3 - 5 = 13

P∩B = a + 5

= 6 + 5 = 11

R ∩ B = C + 5

=7 + 5 = 12

None of the three items of food =  

50 - (3 + 2 + 9 + 6 + 4 + 7 + 5)

What is a graph?

A graph can be defined as a pictorial representation or a diagram that represents data or values.

The cost can be modeled by the function f(x)=4x+3.5, where x represents the number of games bowled.

As per the given question, the required solution would be as:

g(x) = 4x , is the translation of f(x) by subtracting 3.5 units, 2 of 3.

The graph of g(x) would be identical to the graph of f(x), but shifted 3.5 units downward, 3 of 3.

This is because the flat fee for the rental of bowling shoes is not present in the function g(x), so the y-intercept of the graph would be at (0,-3.5) instead of (0,0) in f(x) function.

The slope and the shape of the function will remain the same.

We define a linear equation.

In algebra, a linear equation is one that of the form y=mx+b. The slope is B, and the y-intercept is m. Since y and x are variables, the previous sentence is frequently referred to as a "linear equation with two variables." Bivariate linear equations are linear equations with two variables. Linear equations can be found in many places, including 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. When an equation has the structure y=mx+b, where m denotes the slope and b the y-intercept, it is referred to as being linear.

This is a simple permutations problem! Let's understand, analyze and solve !

First, we understand that there are five spaces that need to be filled: _ _ _ _ _

Second, we should know HOW MANY can go in those spaces: as the problem says, ANY number 0-9,or capital letters,or lower case letters. Numbers 0-9 give us 10 options, all lowercase letters give 26 options, and capital letters give us 26 options. Adding these together, that is 62 options.

Third, we see that since each space can give 62 options (as numbers and letters can be repeated), you multiply 62 by itself five times: 62 * 62 *62 *62 *62. This gives us 916132832 permutations for a password!

**For future reference, it is good to note that if the problem said "each letter, lowercase letter, or capital letter can only be used once". then the answer would be 62 * 61 * 60 * 59 * 58. The reason for this is that once a letter or number is used, it must be removed from the "options" total that we figured out in the 2nd paragraph above. So at first you have all 62 options, but once one is picked it cant be used in the second slot, so now there are only 61 options, so on and so forth.
