Which expression is a sum of cubes?
-27a3b6+8a9b12
-9ab6 +9610
9ab6 + 8a12
27a3b8+8a9b12

Answers

Answer 1

Answer:

The first possible answer, -27a³b^6 + 8a^9b^12, is the sum of cubes.

Step-by-step explanation:

The middle two possible answers involve " a " with no exponent, so these could not be correct.

Looking at the first and fourth possible answers, we see that the first term of -27a3b6+8a9b12 is a perfect cube; it could be re-written as (-3ab²)³.  The second term could be rewritten as (2a³b^4)³.  So the first possible ansswer is the SUM of CUBES.

Which of the following statements is true about the function presented in the table?

a. The slope of the function is 4 and the y-intercept is 2.
b. The slope of the function is 4 and the y-intercept is -2.
c. The slope of the function is -2 and the y-intercept is 4.
d. The slope of the function is 2 and the y-intercept is 4.

Answers

Answer:

C. The slope of the function is -2 and the y-intercept is 4.

Explanation:

The y-intercept is the point when x = 0. On the table when x is 0, y is 4.

The slope of the function is -2 because the y value is going down by 2 for each +1 of x.

      x │ y

    -2 │ 8

     0 │ 4

  ↓ +1   ↓ -2

      1 │ 2

  ↓ +1   ↓ -2

     2 │ 0

Put the following numbers in order from smallest to largest, with the smallest value at the top of the list.
0.085

2/5

1.05
78%

Answers

Answer:

The right order is:

0.0851/32/560%3/478%1.05

Step-by-step explanation:

To identify the right order of the numbers given in order from the smallest to largest, you first must convert all the numbers to the same mode (fractions, decimals or percentages), in this case, I will transform all the numbers to decimals, for this you must divide the fractions or operate the percentages, and you will obtain:

0.085 = 0.085 1/3 = 0.33333333333 60% = 0.6 2/5 = 0.4 3/4 = 0.75 1.05 = 1.05 78% = 0.78

How you can see, in this form is easier than the original form, now you can identify that 2/5 (0.4) is smaller than 60% (0.6) and 1.05 is bigger than 78% (0.78).

Answer:The right order is:

Daja is paid $12.45 an hour. Dahja worked overtime and gets paid double time. What is her double time pay rate? *

Answers

Answer: Her double time pay rate = $24.9 per hour.

Step-by-step explanation:

We have given that, Daja is paid $12.45 an hour.

In other words, her usual time pay rate = $12.45 per hour

Also, If Dahja worked overtime and gets paid double time.

Then, her double time pay rate = 2 x (usual time pay rate) [as double means 2 times]

= 2 x  $12.45 per hour

= $ 24.9 per hour

Hence, her double time pay rate = $24.9 per hour.

i.e. Daja is paid $24.9 an hour for overtime.

Verify the identity and explain how cot(x- pi/2)= -tan x

Answers

Answer:

First, let's recall some usefull information:

- cot(x) = 1/tg(x) = cos(x)/sin(x)

- tan(x) = sin(x)/cos(x)

We also know that:

- cos(x - pi/2) = sin(x)

- sin(x - pi/2) = -cos(x)

Now we can use those relationships and get:

cot(x - pi/2) = cos(x - pi/2)/sin(x -pi/2) = sin(x)/-cos(x) = -tan(x)

So we have verified the identity, and explained step by step why the identity is true.

Find x in the given figure. answers : 55° 125° 35° 60°

Answers

Answer:

Step-by-step explanation:

<6= 125 degrees

<3 = 125 degrees

x = 55 degrees

Answer:

Step-by-step explanation:

55° and ∠4 are corresponding angles made by parallel lines. Therefore, they're congruent.

∠4 = 55°

Lines s and t are parallel lines and ∠4 and x are the interior angles at the same side of the transversal l. Therefore, they're supplementary.

∠4 + x = 180°

55° + x = 180°

x = 180° − 55° = 125°

Answer:

x = -1  y = -1

Step-by-step explanation:

x + 3y = −4

x + 5y = −6

Multiply the first equation by -1

-x - 3y = 4

The add to the second equation to eliminate x

-x - 3y = 4

x + 5y = −6

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

 2y = -2

Divide by 2

2y/2 = -2/2

y = -1

Now solve for x

x+3y = -4

x +3(-1) = -4

x -3 = -4

How would you graph y = -3x + 4? (With visual, please; will give brainliest!)

Answers

Answer:

Step-by-step explanation:

1. Start with the y-intercept, (0,4), plot it on the y-axis.

2. Then using the slope you can find more points on the graph.

- Start with simple x coordinates such as 1,2,3...

- plug each into the equation to find the y cooridnate that makes the x coordinate true.

- write each as a coordinate pair and then plot each pair on the graph.

( you may want to use some negative values for x in order to have ease graphing)

- once you have as many points as you desire, must have atleast 2, draw a line connecting each point.

A cone with a diameter of 6 centimeters and a height of 8 centimeter is drilled into a wooden cube with sides measuring eight centimeters, find the volume of the wood that remains?

Answers

We began be finding the volume of each shape, the we subtracted the volume of the cone from the volume of the cube.

Volume of wood that remain = 436.6 cm^3

Volume of Solids

Given Data

Diameter of cone = 6 cmRadius = 3 cmHeight of cone = 8 cmDimension of Cube = 8 cm

Let us find the volume of the cone

Volume of cone = πr^2h/3

Volume of cone = 3.142*3^2*8/3

Volume of cone = 3.142*9*8/3

Volume of cone = 226.224/3

Volume of cone = 75.408cm^3

Let us find the volume of the cube

Volume of cube = L^3

Volume of cube = 8^3

Volume of cube = 512cm^3

Hence the volume of the wood that remains

= volume of cube - volume of cone

= 512 - 75.408

= 436.6 cm^3

Determine the coordinates of the point on the unit circle corresponding to the given central angle. If necessary round your results to the nearest hundredth 180

Answers

Answer:

Option A. (-1, 0)

Step-by-step explanation:

In the figure attached,

Circle O is a unit circle (having radius r = 1 unit)

If a point A with central angles = θ, is lying on the circle then the coordinates of the point A will be,

x = r.cosθ

x = 1.cosθ = cosθ

and y = r.sinθ

y = 1.sinθ = sinθ

Therefore, coordinates representing the point A will be (cosθ, sinθ).

As per question the given point A is lying at P (a point having central angle θ = 180°)

Coordinates of point P will be

(x', y') → (cos180°, sin180°)

        → (-1, 0)

Therefore, Option A will be the answer.
