Which linear equation represents the graph?A) y=-3x - 2
B) y = 3x + 2
C) y=-1/3x+2
D) y= 1/3 x - 2

Answer:

[tex]-k^2+7k[/tex]

Step-by-step explanation:

Using the given equations, we must find [tex]C-B[/tex]

Start by substituting the given values into the expression:

[tex]C-B\\k-3-(k^2-6k-3)[/tex]

Now, take the terms out of the parentheses.

[tex]k-3-(k^2)-(-6k)-(-3)\\k-3-k^2+6k+3[/tex]

Please note that two negatives make a positive

[tex]k-3-k^2+6k+3[/tex]

Combine like terms:

[tex]-k^2+7k[/tex]

Answer:

a = 12

b = 9

Step-by-step explanation:

b = 3/4(a)

9 = 3/4(12)

9 = 9

a + b = 21

9 + 12 = 21

------------------------------------

b = 3/4(a)

-16(1/4) = (3/4) ((37(1/4))

-16 (1/4) = 447/16

False

----------------------------------

a + b = 21

20 + 11 = 21

31 = 21

False

--------------------------------

a + b = 21

20 + 15 = 21

35 = 21

False

------------------------------

The only correct one was a = 12; b = 9

I hope this helps!

Use Microsoft Excel to produce a scatter chart.

The correlation coefficient is -0.12 and the line of the best fit is y = -0.11x + 385.50

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]

From the table, the value of r:

r = -0.12

The negative correlation exist between year and time.

Since the value of r is not near the -1 or -1 we can say the relation is very weak.

The line of best fit:

y = mx + c

m = -0.11

c = 385.50

y = -0.11x + 385.50

Thus, the correlation coefficient is -0.12 and the line of the best fit is y = -0.11x + 385.50

Answer:

y' = 1 / sinxcosx

Step-by-step explanation:

Given :

y = sinx + cosx / sinx - cosx

Applying quotient rule :

y' = [(sinx - cosx)(cosx - sinx) - (sinx + cosx)(cosx + sinx)] / (sinx -

cosx)²

y' = [sinxcosx - cos²x - sin²x + sinxcosx - (sinxcosx + cos²x + sin²x + sinxcosx)] / (sinx - cosx)²

y' = 2sinxcosx - 2sinxcosx - 2cos²x - 2sin²x / (sinx -cosx)²

y' = -2(sin²x + cos²x) / (sinx - cosx)²

y' = -2 / (sinx - cosx)²

y' = -2 / sin²x - 2sinxcosx + cos²x

y' = -2 / -2sinxcosx

y' = 1 / sinxcosx  [⇒ Final answer]

The volume of the shape shown is 105π cm³

Volume is the amount of space occupied by a three dimensional shape and object.

Volume of the cone = (1/3) * π * (6/2)² * 5 = 15π cm³

Volume of the cylinder = π * (6/2)² * (16 - 5 - 6/2) = 72π cm³

Volume of the hemisphere = (2/3)π * (6/2)³ = 18π cm³

Volume of the shape = 15π cm³ + 72π cm³ + 18π cm³ = 105π cm³

The volume of the shape shown is 105π cm³

Answer:

A. a rotation 90° counterclockwise about the origin, then a translation 3 units up and 7 units right

The sequence of transformation is "a rotation 90° counterclockwise about the origin, then a translation 3 units up and 7 units right" option (A) is correct.

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

The missing figure is attached to the picture, please refer to the picture.

From the figure we can see the transformation applied on the pentagon is a 90° counterclockwise rotation around the origin, followed by a translation of Three units up and seven right

Thus, the sequence of transformation is "a rotation 90° counterclockwise about the origin, then a translation 3 units up and 7 units right" option (A) is correct.

Answer:

  C)  25

Step-by-step explanation:

A function is scaled vertically by multiplying every function value by the scale factor. For some scale factor k, the function g(x) = k·f(x) is a vertically scaled version of the function f(x).

Here, we are given ...

  g(x) = 3/5·f(x)

This means the y-intercept is also scaled:

  g(0) = 3/5·f(0)

  f(0) = 5/3·g(0) . . . . . multiply by 5/3

  f(0) = 5/3·15 = 25

The y-intercept of f(x) is 25.

Answer:

  160

Step-by-step explanation:

  5/4 × 128 = 160

__

You can write the proportion ...

  128 : x = 4 : 5

Then multiplying by 5x gives ...

  (128)(5) = 4x

  x = (5/4)(128) = 160 . . . . divide by 4 and evaluate

Answer:

76

Step-by-step explanation:

5 + X = Y

Y/ 3 = 27

Substitute Y with 5 + X

(5 + X) / 3 = 27

5 + X = 81

X = 76

Answer:

76

Step-by-step explanation:

let the number be n then added to 5 is 5 + n , so

[tex]\frac{1}{3}[/tex] (5 + n) = 27 ( multiply both sides by 3 to clear the fraction )

5 + n = 81 ( subtract 5 from both sides )

n = 76

the number is 76
