Answer:

635.75

Step-by-step explanation:

90π + 2π(7.5)²

~Simplify

90π + 2π(56.25)

~Multiply

282.5 + 2(176.625)

~Simplify

282.5 + 353.25

Answer:

7*(8-6)+3

Step-by-step explanation:

Grouping symbols are parentheses; trial and error can lead you to this answer.

Checking, we must use order of operations (PEMDAS). First, we evaluate what's inside parentheses.

7 * 2 + 3

Then multiply:

Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

3x - y = 4 ( subtract 3x from both sides )

- y = - 3x + 4 ( multiply through by - 1 )

y = 3x - 4 → A

Answer:

2

Step-by-step explanation:

Answer:

2x+2y=2

Step-by-step explanation:

2x+2y=....

So you substitute x for 4 and y for -3.

Which would will give you 2(4)+2(-3). 2·4+2·3 which would give you 8+-6

Then you would add 8 and -6.

8+-6

That should give you 2.

Answer:

y = 14/3 and 2

x = -13/3 and 1

(-13/3, 14/3) and (1, 2)

Step-by-step explanation:

[tex]x + 2y = 5 - - - (a) \\ {x}^{2} - {y}^{2} = - 3 - - - (b)[/tex]

for equation (a)

make x the subject of the formular:

[tex]x = 5 - 2y - - - (c)[/tex]

for equation (b)

[tex] {x}^{2} - {y}^{2} = - 3[/tex]

substitute for x as 5 - 2y in equation (b):

[tex] {(5 - 2y)}^{2} - {y}^{2} = - 3 \\ (25 - 20y + 4 {y}^{2} ) - {y}^{2} = - 3 \\ 25 - 20y + 3 {y}^{2} = - 3 \\ {3y}^{2} - 20y + 28 = 0 \\ (3y - 14)(y - 2) = 0[/tex]

therefore,

[tex]y = \frac{14}{3} \: \: and \: \: 2[/tex]

substitute for all values of y in equation (c):

for y = 14/3:

[tex]x = 5 - 2( \frac{14}{3} ) \\ \\ x = 5 - \frac{28}{3} \\ \\ x = - \frac{13}{3} [/tex]

for y = 2:

[tex]x = 5 - 2(2) \\ x = 5 - 4 \\ x = 1[/tex]

Answer:

(1, 2)

(-13/3, 14/3).

Step-by-step explanation:

x + 2y = 5

x² - y² = -3​

From the first equation x = 5 - 2y

Substitute for y in the second equation:

(5 - 2y)^2 - y^2 = -3

25 + 4y^2 - 20y - y^2 = -3

3y^2 - 20y + 28 = 0

Factoring:-

(3y - 14(y  -  2)   = 0

y = 2, 14/3.

So when y = 2, x = 5 - 2(2) = 1.

When y = 14/3, x = 5 - 2(14/3) = -13/3.

Checking the results in the second equation:

(1, 2):-

1^2 - 2^2 = -3    Correct.

(-13/3, 14/3):-

(-13/3)^2 - (14/3)^2 = -3   Correct.

Answer:

A and C

Step-by-step explanation:

A

when x = 2 , that is x > 1 then f(x) = x² , that is

f(2) = 2² = 4 ← True

B

when x = 5, that is x > 1 then f(x) = x² , that is

f(5) = 5² = 25 ≠ 1 ← not true

C

when x = 1 then f(x) = 5 , that is

f(1) = 5 ← True

D

when x = - 2 , that is x < 1 , then f(x) = 2x , that is

f(- 2) = 2(- 2) = - 4 ≠ 4 ← not true

The component form of the vector that translates will be 11i - 17j.

A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.

The translation does not change the shape and size of the geometry. But changes the location.

The point A(-4, 8) is translated to the point A'(7, -9). Then the rule of the transformation is given as,

(7, - 9) = (- 4 + x, 8 + y)

Compare the abscissa, then we have

7 = - 4 + x

x = 7 + 4

x = 11

Compare the ordinate, then we have

y + 8 = - 9

y = - 8 - 9
y = - 17

The component form of the vector that translates will be 11i - 17j.

Answer:

TU = 29

Step-by-step explanation:

TU + UV = TV , substitute values

9x + 2 + 5 = 14x - 8 , that is

9x + 7 = 14x - 8 ( subtract 14x from both sides )

- 5x + 7 = - 8 ( subtract 7 from both sides )

- 5x = - 15 ( divide both sides by - 5 )

x = 3

Then

TU = 9x + 2 = 9(3) + 2 = 27 + 2 = 29
