Hey there :)

g ( x ) = 2x² - 11x

For g ( - 1 ) , you need to substitute - 1 in place of x

g ( - 1 ) = 2 ( - 1 )² - 11 ( - 1 )
           = 2 ( 1 ) + 11
           = 2 + 11
           = 13  →  Your answer

A prism with a base area of 5 ft² and a height of 10 ft is dilated by a factor of 65 . What is the volume of the dilated prism?
mina [271]

Answer:

The volume of the dilated prism is 86.4ft^3.

Step-by-step explanation:

The original prism has base area 5ft^2 and a height of 10ft.

The volume of the original prism is v=5\times 10=50ft^3.

The prism is dilated by a scale factor of k=\frac{6}{5}.

To find the volume of the dilated prism, we multiply the volume of the original prism by k^3=\frac{216}{125}.

V=\frac{216}{125} \times 50ft^3

\Rightarrow V=86.4ft^3

1. 1/2- you count the total (8) and then count the two and all the numbers greater than 5( don’t count 5) that is 4 so it would be 4/8 simplified to 1/2

2. 1/2- count the total (still 8) and how many prime numbers there are (4- 2,3,5, and 7) the answer is 4/8 simplified to 1/2

In health class, students record the weights of the sandwiches they have for lunch. The weights are shown in the line plot below
Dvinal [7]
To find the average weight, you need to add all of the numbers and then divide them
I'll start off by doing this:
1/8+1/8 = 2/8
1/4+1/4+1/4+1/4 = 1
3/8+3/8 = 6/8
1/2+1/2 = 1
then I'll add them together:
2/8+6/8 = 1
1 + 1 + 1 =3
now we need to divide the amount of numbers. the amount of sandwiches weighted (10) will have to be divided
therefore, we get 3/10. because this can't be simplified, this will be your final answer.
