Answers

Answer 1
Answer:

Answer:

option D

(1, -2)

Step-by-step explanation:

Given in the question are coordinates,

(–1, 2) and (3, –6)

x1 = -1

x2 = 3

y1 =2

y2 = -6

Formula to calculate midpoint

(x1+x2)/(2),(y1+y2)/(2)

(-1+3)/(2),(2-6)/(2)

(2)/(2),(-4)/(2)

(1,-2)

No responses yet... John is making trail mix based on a recipe that combines 6 cups of nuts with 5 cups of granola. John has 36 cups of nuts. How many cups of trail mix (total) does he have?

Answers

Given:

A recipe combines 6 cups of nuts with 5 cups of granola.

John has 36 cups of nuts.

To find:

Number of cups of trail mix (total) does he have.

Solution:

The recipe combines 6 cups of nuts with 5 cups of granola.

The recipe combines 1 cup of nuts with (5)/(6) cups of granola.

The recipe combines 36 cup of nuts with 36* (5)/(6) cups of granola.

So, the number of cups of granola in trail mix is

Granola=36* (5)/(6)

Granola=6* 5

Granola=30

Total number of cups = cups of nuts + cups of granola.

                                    =36+30

                                     =66

Therefore, the total number of cups in trail mix (total) he have, is 66.

21x^3 + 6x^2 - 28x - 8 factor this expression with work please?

Answers

21x^3 + 6x^2 - 28x - 8 \n \n 3x^2 (7x + 2) - 4(7x + 2) \n \n (7x + 2)(3x^2 - 4) \n \n

The final result is: (7x + 2)(3x² - 4).
21x^3+6x^2-28x-8
(21x^3+6x^2)-(28X+8)
3x^2(7x+2)-4(7x+2)
3x^2-4=0 and 7x+2=0

Doris put $4000 in a 2 year cd paying 6% interest, compounding monthly. after 2 years, she withdrew all her money. what was the amount of the withdraw?

Answers

For the answer to the question above asking what was the amount of the withdraw if Doris put $4000 in a 2-year cd paying 6% interest, compounding monthly. after 2 years, she withdrew all her money?

First year Interest: I(1) = 4000[(1.005)^12 - 1] = 246.71 = penalty for early withdrawal 
Value after two years: P(2) = 4000(1.005)^24 = 4508.64 

Value after 2 years with penalty: V = 4000(1.005^24 - 1.005^12 + 1) = $4261.93

Answer:

Value after two years: P(2) = 4000(1.005)^24 = **** 4508.64 ***
