Answer: The value of g(-1)=-2

Step-by-step explanation:

The given function : g(x) = 2x^4 + 3x^3 - x^2

To find the value of g(-1), we  need to substitute x= -1 in the above function, we get

g(-1) = 2(-1)^4 + 3(-1)^3 - (-1)^2\\\\\text{Simplify}\\\\\Rightarrow\ g(-1)=2(1)+3(-1)-(1)\\\\\Rightarrow\ g(-1)=2-3-1\\\\\Rightarrow\ g(-1)==-2

Therefore, the value of g(-1)=-2

Plug -1 for x. So
2(-1)^4 + 3(-1)^3 - (-1)^2
2(1)+3(-1)+1
2-3+1

Luda [366]

Answer:

<em>See the graph with both lines attached</em>

A) From the tables we see the constant change of values in the second column and the initial value is zero.

This represents a proportional relationship for both tables.

B) <u>Revel</u>

  • Rate of change is 5 per hour, the equation is:
  • y = 5x, where y is cost, x - is the number of hours

<u>Scooters</u>

  • Rate of change is 6 per hour, the equation is:
  • y = 6x, where y is cost, x - is the number of hours

C) <u>When x = 12</u>,

  • y = 5*12 = $60 for Revel
  • y = 6*12 = $72 for Scooters

D) <u>The point (4, 24) represents that:</u>

  • The cost of 4 hours is $24

E) The second table has confusing titles (days and number of cell phones) but if we assume its same as the first table, then Revel has lower rate as 5 < 6.

Comparing the prices and the graph, Revel has better rate per hour.

A label that wraps around a box of golf balls covers 75 percent of its lateral surface area. What is the value of x?
mestny [16]

Answer:

To find the area of the rectangular prism, use the formula:

A = width x height x length

A = 2 x 2 x 3

A = 12

Now multiply A with 0.75

12 x 0.75 = 9

x = 9 in³

hope this helps
