Answer:

2

8/4=2

I think this is pretty easy:

D/4=(answer)

8/4=2/1

2/1=2

Answer:

2

Step-by-step explanation:

So if D=8, 8/4

8 divided by 4 is 2

Answer:

a2 + b2 = c2

Step-by-step explanation:

Answer:

why? also the answer is 1.6y+y-4/15y+7/6y=21/3

We move all terms to the left:

1.6y+y-4/15y+7/6y-(21/3)=0

Domain of the equation: 15y!=0

y!=0/15

y!=0

y∈R

Domain of the equation: 6y!=0

y!=0/6

y!=0

y∈R

We add all the numbers together, and all the variables

1.6y+y-4/15y+7/6y-7=0

We add all the numbers together, and all the variables

2.6y-4/15y+7/6y-7=0

We calculate fractions

2.6y+(-24y)/90y^2+105y/90y^2-7=0

We multiply all the terms by the denominator

(2.6y)*90y^2+(-24y)+105y-7*90y^2=0

We add all the numbers together, and all the variables

(+2.6y)*90y^2+(-24y)+105y-7*90y^2=0

We add all the numbers together, and all the variables

105y+(+2.6y)*90y^2+(-24y)-7*90y^2=0

Wy multiply elements

-630y^2+105y+(+2.6y)*90y^2+(-24y)=0

We get rid of parentheses

-630y^2+105y+(+2.6y)*90y^2-24y=0

We add all the numbers together, and all the variables

-630y^2+81y+(+2.6y)*90y^2=0

Step-by-step explanation:

Given:

Parent function is [tex]f(x)=5^x[/tex].

New function is [tex]y=-2(5)^{3x}+8[/tex].

To find:

The equation of function after each transformation.

Solution:

We have,

[tex]f(x)=5^x[/tex]

The equation of parent function is

[tex]y=5^x[/tex]

1. [tex]y=5^{3x}[/tex]             (Horizontal compression by factor 3)

2. [tex]y=2(5)^{3x}[/tex]         (Vertical stretch by factor 2)

3. [tex]y=-2(5)^{3x}[/tex]         (Reflected across x-axis)

4. [tex]y=-2(5)^{3x}+8[/tex]        (Shift 8 units above)

Therefore, these are the required answers.

Answer:

  30 m²

Step-by-step explanation:

The figure can be thought of as a 6 m × 6 m square with a triangle cut off of the corner. That triangle has a base of 6-3 = 3 m, and a height of 6-2 = 4 m. Then the area of the figure is ...

  pen area = square area - triangle area

  pen area = (6 m)² - (1/2)(3 m)(4 m)

  pen area = 36 m² -6 m²

  pen area = 30 m²

__

The formula for the area of a square of side s is ...

  A = s²

The formula for the area of a triangle with base b and height h is ...

  A = (1/2)bh

It is useful to remember these formulas.

Answer:

A is the answer

Step-by-step explanation:

Isolate the radical, then raise each side of the equation to the power of its index.

Answer:

C

Step-by-step explanation:

30 x 4 = 120 justina collection is 30 and shamea's is 120, 30 + 120 = 50

Answer:

30

Step-by-step explanation:

There's a proper way to do this, but I forgot.

I ended up just plugging the numbers in to see if they worked;

120(4) + 120 is too much to be 150;

40(4) + 40 is 200, still too much to be 150;

30(4) + 30 is 150, exactly

So your answer is C, 30.

Hope this helps!

Answer:

[tex]A_2 = 7.5cm^2[/tex]

Step-by-step explanation:

The attachment completes the question

Given

[tex]Area = 15cm^2[/tex]

Required

Area of green triangle

[tex]The\ area\ of\ a\ parallelogram\[/tex] is calculated as

[tex]A_1 = b * h[/tex]

and

[tex]A_1 = 15cm^2[/tex]

Where:

[tex]b=base[/tex]

[tex]h = height[/tex]

Because the triangle shares exact base and height with the parallelogram, the area of a triangle is calculated as

[tex]A_2 = \frac{1}{2} * b * h[/tex]

Recall that:

[tex]A_1 = b * h[/tex]

So, we have:

[tex]A_2 = \frac{1}{2} *A_1[/tex]

Substitute [tex]15cm^2[/tex] for [tex]A_1[/tex]

[tex]A_2 = \frac{1}{2} * 15cm^2[/tex]

[tex]A_2 = \frac{ 15cm^2}{2}[/tex]

[tex]A_2 = 7.5cm^2[/tex]

The area of the triangle is 7.5cm^2

Answer:

6+18x

Step-by-step explanation:

You typically would use PEMDAS in this situation but in the parenthesis, you can't add the 3 and the 9x together, so you just skip to 2*3 and 2*9x

Answer:

Step-by-step explanation:

if were trying to simplify it it would be 6+18x

Answer:

  4)  (4, 0)

Step-by-step explanation:

I find it useful to graph the inequalities and the points.

The point on the dashed line is not in the solution set. The only point in the doubly-shaded area is (4, 0), choice (4).

__

Another method of choosing the points is to try them in the inequalities. I find it easier to do the math if the inequalities are written in standard form:

  2y < x +8 . . . . . multiply the first by 2

  x -2y > -8 . . . . . add -8-2y and swap sides. This is the first inequality.

__

  y ≥ -x +1

  x + y ≥ 1 . . . . .  add x. This is the second inequality

__

For the four points in the first inequality, we have ...

  1) -5 -2(3) = -11  . . .  not greater than -8

  2) 0 -2(4) = -8 . . . not greater than -8

  3) 3 -2(-5) = 13 . . . greater than -8, satisfies the first inequality

  4) 4 -2(0) = 4 . . . greater than -8, satisfies the first inequality

__

So, the two points that might possibly work are (3, -5) and (4, 0). Here, we try these in the second inequality.

  3) 3 -5 = -2 . . . less than 1

  4) 4 + 0 = 4 . . . greater than 1, satisfies the second inequality

The only point listed that is a solution to the system is (4, 0), point 4.

Answer: [tex]P(x)= - 0.4x ^ 3 +100x^2-900x+500[/tex]

Step-by-step explanation:

Given: Monthly cost : [tex]C(x) = 600x ^ 2 + 300x[/tex]

Monthly revenue : [tex]R(x) = - 0.4x ^ 3 + 700x ^ 2 - 600x + 500[/tex], where x is in thousands of books sold.

Profit = Revenue - Cost

Now , Profit function : P(x) =  R(x)-C(x)

[tex]=- 0.4x ^ 3 + 700x ^ 2 - 600x + 500 - ( 600x ^ 2 + 300x )\\\\= - 0.4x ^ 3 + 700x ^ 2 - 600x + 500 -600x ^ 2 - 300x\\\\= - 0.4x ^ 3 +100x^2-900x+500[/tex]

Hence, [tex]P(x)= - 0.4x ^ 3 +100x^2-900x+500[/tex]
