Given f(x)=x2-1/x+4 find f(-3)

f(-3)=(-3)2 - 1 / -3 + 4

f(-3)= -6 -1 / -3 + 4

f(-3)= -7/1

f(-3)=-7

f(-3)= -6 -1 / -3 + 4

f(-3)= -7/1

f(-3)=-7

2 yd

7yd

**Answer:**

136

**Step-by-step explanation:**

The formula you use is as follows:

A=2(WL+HL+HW)

You plug in each number to get this equation

A=2[(6*7)+(2*7)+(2*6)]

A=2(42+14+12)

A=2(68)

A=136

13. The function y = 40(x - 1) + 70 can be used to determine the cost in dollars

for renting a trampoline park for a birthday party for x hours. What is the rate of

change of the cost in dollars to rent the trampoline park with respect to time?

A

$30 per hour

$40 per hour

B

с

$60 per hour

D

$110 per hour

**Step-by-step explanation:**

the function actually is

y = 40(x - 1) + 70 = 40x - 40 + 70 = 40x + 30

still, the slope (the factor of x) is 40.

that means y (the cost) increases by 40 for every additional hour (x increases by 1).

so, the rate of change (slope) is 40/1 = $40 per hour.

Find the mean of the data

Explanation:

Refer to the table below. I've added a third row where I multiplied each x value with its corresponding frequency value f. We can refer to this row as the xf row.

Once we know the xf values, we add them up to get 245.

We'll then divide that result over the sum of the frequency values (add everything in the second row). The sum of the frequency values is 39.

So the mean is approximately: 245/39 = 6.282051 which rounds to **6.282**

Notice that this mean value is fairly close to the x value which has the highest frequency.

Mr. Bailey announced the grade distribution for

his science fair projects. Of the 36 students in the

class, 12 earned A's, 18 earned B's, and 6 earned

Identify the first five terms of the sequence in which a1 = 3 and an = 4an−1− 5 for n ≥ 2.

**Step-by-step explanation:**

a1 = 3

an = 4an-1 - 5

a2 = 4×3 - 5 = 12 - 5 = 7

a3 = 4×7 - 5 = 28 - 5 = 23

a4 = 4×23 - 5 = 92 - 5 = 87

a5 = 4×87 - 5 = 348 - 5 = 343

**Answer:**

3, 7, 23, 87, 343

**Step-by-step explanation:**

Using the recursive rule and a₁ = 3 , then

a₂ = 4a₁ - 5 = 4(3) - 5 = 12 - 5 = 7

a₃ = 4a₂ - 5 = 4(7) - 5 = 28 - 5 = 23

a₄ = 4a₃ - 5 = 4(23) - 5 = 92 - 5 = 87

a₅ = 4a₄ - 5 = 4(87) - 5 = 348 - 5 = 343

what does a discrete quantitative variable mean?

**Answer:**

A discrete quantitative variable is one that can only take specific numeric values (rather than any value in an interval)

**Step-by-step explanation:**

A discrete quantitative variable is one that can only take specific numeric values (rather than any value in an interval), but those numeric values have a clear quantitative interpretation. Examples of discrete quantitative variables are number of needle punctures, number of pregnancies and number of hospitalizations.
