For the function f defined by f(x) = 2x^2 – 3x, evaluate: f(x+3)

Answers

Answer 1
Answer:

Answer:

2x² + 9x + 9

Step-by-step explanation:

To evaluate f(x + 3) substitute x = x + 3 into f(x), that is

f(x + 3) = 2(x + 3)² - 3(x + 3) ← expand (x + 3)² using FOIL

            = 2(x² + 6x + 9) - 3(x + 3) ← distribute both parenthesis

           = 2x² + 12x + 18 - 3x - 9 ← collect like terms

            = 2x² + 9x + 9
Answer 2
Answer: Answer: f(5) = 14 should be the answer

What is interest?

Simpleinterest is defined as the percentage of earnings on the lending for a period of time

Here,
Principal = 1000
Rate = 9%
Time = 3 / 12 = 0.25 years
So,
Interest = Principal × rate × time
interest = 1000 × 0.09 × 0.25
Interest = $22.5

Thus, the required interestpaid by Barry is given as, $22.5.

One brother eats 3/5and the other brother eat 3/10 of the cereal how much more does the other brother eat

Answers

In this question there are information's of immense importance and that can go a long way in helping to solve the given question. It is given that one brother eats 3/5 of the cereal and the other brother eats 3/10 of the cereal. The answer that needs to be found is that the amount of cereal the other brother eats more.
The amount of cereal eaten more by the other brother = (3/5) - (3/10)
                                                                                       = ( 6 - 3)/ 10
                                                                                       = 3/10
So the other brother does not eat more, but the first brother has eaten 3/10 more than the other brother.
well 3/5 is equal to 6/10
then you would subtract 6/10-3/10=3/10

12.5,-10,-7.5,x;the mean is 11.5

Answers

Answer:

Hi!

The correct answer is x = 51.

Step-by-step explanation:

By definition the mean formula is:

mean = (x_1 + x_2 + x_3 + ... + x_n)/(n)

where x are the samples of the data set and n the numbers of elements in the set.

In this case:

  • n = 4
  • mean = 11.5

Replacing the data on the general formula:

11.5 = (12.5 - 10 - 7.5 + x)/(4)

Solving the equation step by step,

4 * 11.5 = -5 + x}

46 = -5 + x}

51 = x}

True or False: For the depreciation formula, A = C(1 - r)t, the A value will always be greater than the C value.

Answers

Answer: False

"Depreciating" means "going down", so the value is decreasing. The value of A will always be smaller than C. For example, if the item is worth $100 today and it drops to $80, then it depreciates in value. In this example, C = 100 and A = 80 so A > C is false
