Answer:

3. (7, 15)

4. (7, 15) means that Carter is 7 blocks right and 15 blocks up from the origin.

5. (6, 7)

6. (9, 5)

Step-by-step explanation:

3. school is at point (3, 13)

If Carter travels 4 blocks right and 2 blocks up then add 4 to the x-coordinate and 2 to the y-coordinate of the school:

(3 + 4, 13 + 2) = (7, 15)

4. (7, 15) means that Carter is 7 blocks right and 15 blocks up from the origin.

5. To calculate his starting position reverse his journey, so travel 3 blocks right and 8 blocks down from the baseball diamond

baseball diamond = (3, 15)

So (3 + 3, 15 - 8) = (6, 7)

6. Burger joint = (14, 15)

To calculate his starting position reverse his journey, so travel 5 blocks left and 10 blocks down from burger joint

So (14 - 5, 15 - 10) = (9, 5)

**if you are traveling right, you are adding to the x-coordinate

**if you are traveling left, you are subtracting from the x-coordinate

**if you are traveling up, you are adding to the y-coordinate

**if you are traveling down, you are subtracting from the y-coordinate

3. 4,2 or you can say x= 4 and y=2

4. see the answer in attach file

5. he traveled 3 blocks left and 8 blocks up so he starts from 13 means (coordinate y)

6. he starts from coordinate x

The ratio of students to teachers at a school is 19 to 1 how many students are there in each total number of people

vladimir2022 [97]

Question:

The ratio of students to teachers at a school is 19 : 1. How many students are there in each total number of people?

A: 100 people

b. 280 people

c.440 people

d.760 people

Answer:

A )95 students and 5 teachers

B)266 students and 14 teachers

C)418 students and 22 teachers

D)722 students and 38 teachers

Step-by-step explanation:

A: 100 people

Ratio = 19 : 1

The sum of the ratio is 19 + 1 = 20

Scale factor = $\frac{100}{20}$

scale factor = 5

The number students is $19 \times 5$ = 95

The number of teachers is $1 \times 5$ = 5

b. 280 people

Ratio = 19 : 1

The sum of the ratio is 19 + 1 = 20

Scale factor = $\frac{280}{20}$

scale factor = 14

The number students is $19 \times 14$ = 266

The number of teachers is $1 \times 14$ = 14

c.440 people

Ratio = 19 : 1

The sum of the ratio is 19 + 1 = 20

Scale factor = $\frac{440}{20}$

scale factor = 22

The number students is $19 \times 22$ = 418

The number of teachers is $1 \times 22$ = 22

d.760 people

Ratio = 19 : 1

The sum of the ratio is 19 + 1 = 20

Scale factor = $\frac{760}{20}$

scale factor = 38

The number students is $19 \times 38$ = 722

The number of teachers is $1 \times 38$ = 38

Find the eigenvalues of the matrix: [-43 0 80] [40 -3 80] [24 0 45]

saveliy_v [14]

Answer:

-3

1 + 4 sqrt( 241 )

1 - 4 sqrt( 241 )

Step-by-step explanation:

We need minus lambda on the entries down the diagonal. I'm going to use m instead of the letter for lambda.

[-43-m 0 80]

[40 -3-m 80]

[24 0 45-m]

Now let's find the determinant

(-43-m)[(-3-m)(45-m)-0(80)]

-0[40(45-m)-80(24)]

+80[40(0)-(-3-m)(24)]

Let's simplify:

(-43-m)[(-3-m)(45-m)]

-0

+80[-(-3-m)(24)]

Continuing:

(-43-m)[(-3-m)(45-m)]

+80[-(-3-m)(24)]

I'm going to factor (-3-m) from both terms:

(-3-m)[(-43-m)(45-m)-80(24)]

Multiply the pair of binomials in the brackets and the other pair of numbers;

(-3-m)[-1935-2m+m^2-1920]

Simplify and reorder expression in brackets:

(-3-m)[m^2-2m-3855]

Set equal to 0 to find the eigenvalues

-3-m=0 gives us m=-3 as one eigenvalue

The other is a quadratic and looks scary because of the big numbers.

I guess I will use quadratic formula and a calculator.

(2 +/- sqrt( (-2)^2 - 4(1)(-3855) )/(2×1)

(2 +/- sqrt( 15424 )/(2)

(2 +/- sqrt( 64 )sqrt( 241 )/(2)

(2 +/- 8 sqrt( 241 )/(2)

1 +/- 4 sqrt( 241 )

Let s be the annual sales (in millions) for a particular electronic item. The value of s is 55.6 for 2005. What does s = 55.6

svetlana [45]

Answer:

Annual sales of a particular electronic item in 2006 was 54.5 million.

Step-by-step explanation:

We have been given that s is the annual sales (in millions) for a particular electronic item. The value of s is 54.5 for 2006. We are asked to find the meaning.

Since s represent the annual sales (in millions) for a particular electronic item, therefore, means that annual sales of a particular electronic item in 2006 was 54.5 millions.
