Answer:

a_7=-15

Step-by-step explanation:

a_n  is given as the nth term of a sequence.

We want to find a_7 , which means we find the 7th term of the sequence.

Here, we simply substitute "7" into "n" of the formula given for  a_n  to find the value of the 7th term of the sequence.

We show this below:

a_n=-3(n-2)\\a_7=-3(7-2)\\a_7=-3(5)\\a_7=-15

So the 7th term is "-15"

Answer: Hope this helps!

Step-by-step explanation:

Area of a trapezoid formula base a+base b/2*h

Base a is the top length (22.5)

Base b is the bottom length (49.9)

Add those two lengths together (22.5+49.9=72.4)

Divide that by two (72.4/2=36.2)

Then multiply that by the height (36.2*23.8=861.56)

So your area is 861.56

Jefferson's Popcorn & Roasted Nuts Shop sells cone-shaped bags of roasted cashews, shown below. What is the volume of the ba
DanielleElmas [232]

The volume of the bag of nuts is the amount of nuts it can contain

The volume of the bag of nuts is 84.78 cubic inches

<h3>How to determine the volume of the bag?</h3>

From the figure, we have the following parameters:

  • Radius, r = 3 in
  • Height, h = 9 in

The volume of a cone is calculated using:

V = 1/3 πr^2h

Substitute the known values

V = 1/3  * 3.14 * 3^2 * 9

Evaluate the product

V = 84.78

Hence, the volume of the bag of nuts is 84.78 cubic inches
