93. Let f(x) = 3x - 1 and g(x) = x + 5. Evaluate the following limits. (a) lim x→3 f(g(x)]
(b) lim x→3 g[f(x)]

Answers

Answer 1

Answer:

a) 23 and b) 13

Step-by-step explanation:

I. If f(g(x)) is composit function

Find fog and gof

     fog = 3(g) - 1

           = 3(x+5) -1

           = 3x + 15 -1

           = 3x + 14

    gof = (f) + 5

          = (3x - 1) +5

          = 3x + 4

II. Fill in a) and b) question

            lim x -> 3 fog

           = 3(x) + 14

           = 3(3) + 14

          = 9 + 14

       a)  = 23

            lim x-> 3 gof

           = 3x + 4

           = 3(3) + 4

           = 9 + 4

        b)  = 13

c
She earned $75 and she spent $22.25
d
She earned $75 and spent $23.75

Answers

The answer is C. She earned $75 and spent $22.25

We can take our totals that were earned before she started spending and combine them. On concurrent days she received a total of $75. She got $40 one day and $35 the next. In between those days she spent, $9.75 and $12.50. She spent a total of $22.25. Once again making the answer option C

during the movie fundraising event the concession stand at the auditorium sells popcorn fruit and drinks the price of a box of popcorn is 0.50 more than

Answers

Using the information in the exercise to develop the system of equations and using the substitution method, the following answers are found:

The system of the linear equations is P = F + 0.50, 2D = 3F - 0.50, and 2P + F + 3D = 7.75, where P = The price of a box of popcorn, D = The price of a drink, and F = The price of a piece of fruit. By other hand, the price of each item is: Popcorn = $1.50, Drink = $1.25, and Fruit = $1.

Solution of the system of equations by the Substitution Method.

Taking into account the information given in the exercise, we can write the next equations:

P = F + 0.502D = 3F - 0.502P + F + 3D = 7.75

Where:

P = The price of a box of popcorn.D = The price of a drink.F = The price of a piece of fruit.

Since all equations have the variable F, we are going to use it as a key variable to represent the other variables in terms of F.

In the first equation we should not do anything, since P is in terms of F, in the second case the variable D is also in terms of F, but we need to find the value of just D, by this:

2D = 3F - 0.50D = (3F - 0.50) / 2D = 1.5F - 0.25

We proceed to substitute the first and second equations in the third equation:

2P + F + 3D = 7.752 (F + 0.50) + F + 3 (1.5F - 0.25) = 7.75

And we solve for the variable F:

2F + 1 + F + 4.5F - 0.75 = 7.757.5F + 0.25 = 7.757.5F = 7.75 - 0.257.5F = 7.5F = 7.5 / 7.5F = 1

Now, we can solve for the variable D with the second equation:

2D = 3F - 0.502D = 3 * (1) - 0.502D = 3 - 0.502D = 2.5D = 2.5 / 2D = 1.25

Finally, we can solve for the variable P with the first equation:

P = F + 0.50P = 1 + 0.50P = 1.50

So, we have the price of each item:

Popcorn = 1.50Drink = 1.25Fruit = 1

Rewrite as:

1/8, 2/7, 3/6, 4/5

We observe the numerators: 1, 2, 3, 4 and denominators: 8, 7, 6, 5

The next two terms are:

5/4 and 6/3

or

5/4 and 2

The denominator is decreasing by 1 and numerator is increasing by 1

Next term

For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number

If you mean a 20 inch cube box then the answer is 125. Since 4 inch cubes have dimensions 4x4x4 and 20 inch cubes have dimensions 20x20x20. Then we can find the answer by dividing 20x20x20 by 4x4x4 which is equal to 5x5x5 as 20/4 = 5. Therefore the answer is 5x5x5 which is 125.
