The sum of 3 terms in A. P.is - 3 and their product is 8, then sum of squares of the numbers is

Answers

Answer 1
Given:

sum of the numbers = - 3

Product of the numbers = 8

Find:

sum of squares of the numbers

Solution:

Let the three terms be a - d , a , a + d.

sum of the numbers = - 3

→ a - d + a + a + d = - 3

→ 3a = - 3

→ a = - 3/3

→ a = - 1

Also,

Product of the numbers = 8

→ (a - d) * (a) * (a + d) = 8

Putting the value of a and using (a + b) * (a - b) = a² - b² we get,

→ [ (- 1)² - d² ] = 8/ - 1

→ 1 - d² = - 8

→ 1 + 8 = d²

→ 9 = d²

→ d = 3

Hence,

a - d = - 1 - 3 = - 4 a = - 1 a + d = - 1 + 3 = 2

Now,

Finding Sum of their squares :

→ (a - d)² + a² + (a + d)²

→ ( - 4)² + ( - 1)² + (2)²

→ 16 + 1 + 4

→ 21

Hence, the sum of the squares of the three terms is 21.

I hope it will help you.

Answers

Answer:

A) where any seats empty? How do u know?

Yes, there were empty seats.

B) if ur answer to part a is yes find the number of empty seats

440 empty seats

Step-by-step explanation:

A) where any seats empty? How do u know?

Yes there were empty sits

B) if ur answer to part a is yes find the number of empty seats

We are told that the theater had the theartre has 49 rows with 48 seats in each row

This means the total number of seats in the theater =

49 × 48 = 2352 seats

The total number of people in the theater

= Number of teacher + Number of Students

= 1854 + 58 = 1912 people

This means 1912 seats were occupied

The number of empty seats = 2352 - 1912

= 440 seats

The square shown is divided into five cells. Starting at any cell, how many paths can be drawn that move only to adjacent cells and that include all five cells?

Answers

Answer:

150 (not sure)

Step-by-step explanation:

Paths that only touch 5 points unrepeatedly:

I used a tree diagram to list all the workable paths, taking cell A as an example:

ABCDEABCEDABECDABEDCAEBCDAEDCBADCBEADCEBADEBCADECB

2*(3x2 - 1) = 10

When you start at A you would have 3 choices, but after that only two, and since DB or BD can't happen and crossing B and D for the second step is the same, I double it.

Paths that touch 5 points and reapeat one of them:

2*(3x2x2 - 1x2) = 20

Paths that touch 5 points and repeat two of them:

2*(3x2x2x2-1x2x2) = 40

Paths that touch 5 points and repeat three of them:

2*(3x2x2x2x2-1x2x2x2) = 80

The sum of the answers in these 4 senarios is the final answer.

Mr. Wong wants to purchase 12 new smoke detectors for his house. Store A sells each smoke detector for $17 and Store B sells each smoke detector for $24. If Mr. Wong purchases all his smoke detectors at Store A, how much less will he spend than if he purchased all the smoke detectors at Store B?

Answers

Answer: $84

Step-by-step explanation:

Price of  smoke detector in Store A = $17

Price of  smoke detector in Store B =  $24

Total detectors bought = 12

Price of 12 detectors in Store A = $17 x 12 = $204

Price of 12 detectors in Store B =  $24 x 12 = $ 288

Difference = $ 288 -$ 204 = $84

Hence, he will spend $84 less than if he purchased all the smoke detectors at Store B.

Tina borrows $4,000 at a simple interest rate of 2% and plans on paying their loan over 6 years. What is the total amount Tina will have to repay on both the loan and interest? *

Answers

Answer:

$4480

Step-by-step explanation:

Given

principal= $4000

rate= 2%= 0.02

time= 6 years

We know that the expression for simple interest is given as

Interest = PRT

solving for the interest we have

I=4000*0.02*6

I=480

Therefore Tina is paying an interest of $480

Tina will have to repay on both the loan and interest of

=4000+480

=$4480

Answers

Answer:

16.67%

Step-by-step explanation:

A vet taught the practice saw 28 cats

The actual number was 24 cats

Therefore the percent value can be calculated as follows

= approximate value- exact value/exact value × 100

= 28-24/24 × 100

= 4/24 × 100

= 0.16666 × 100

= 16.666

= 16.67 % ( to the nearest hundredth)
