If a = 2.3 units, b = 3 units, c = 5 units, and d = 7 units, what is the volume of the two prisms?a 126 cubic units
b 71.45 cubic units
c 89.45 cubic units
d 74.75 cubic units

Answers

The volume of the two prism is,

⇒ 117.5 cubic units

What is Multiplication?

Multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Now, Find the volume of each prism as;

Volume of bottom = l • w • h

                           = 6 units • 2.5 units • 2.5 units

                          = 37.5 cubic units

Volume of top = l • w • h

                      = 4 units • 2.5 units • 8 units

                     = 80 cubic units

Then, add the volumes as;

⇒ 37.5 cubic units + 80 cubic units

⇒ 117.5 cubic units

Thus, The volume of the two prism is,

⇒ 117.5 cubic units

#SPJ2

First prism= 2.3*3*7= 48.3 cubic
Second prism= 2.3*2.3*5= 26.45 cubic
Then you add two cubics together 48.3+26.45 and you get 74.75

GCF(24, 36, 60) = 12
To find the greatest common factor of any set:
1) List their prime factorizations.

24 = 2³ × 3
36 = 2² × 3²
60 = 2² × 3 × 5

2) Multiply together any factor these all share.

2² × 3 = 12 (GCF)

Find the derivative of f(x) = negative 9 divided by x at x = -8.

Answers

The derivative given in the question is 
f(x) = - 9 /x
When x = -8, then
f(-8) = 9/8
The negative sign on the right hand side gets cancelled out. From the above deduction, it can be easily concluded that the answer is 9/8. I hope that this is the answer that you were looking for and the answer has actually come to your desired help.

Molly is on a game show. To win $1,000,000, she must answer this question: What key features are necessary—and how are the features used—to create the sketch of a polynomial function? What is Molly's winning answer? Explain in complete sentences.

Answers

A polynomial function refers to a function expressed by a polynomial, with only positive integer (non-fraction, non roots) values for the exponents, such as:

(a_(1))^(n) + (a_(2))^(n-1) + (a_(3))^(n-2) +...+ a_(n)

Remember that (1)/(x) can be written as ,
