9x^{2} - x^{3} - 9 + x
What is ^^^ factored?

Answer:

[tex]x \leq 6[/tex]

Step-by-step explanation:

because the ray travels left, x has to be lower than 6, and since it is a closed circle, means that 6 is included in the answer, so x is less than or equal to 6.

Answer:

  x = 7

Step-by-step explanation:

The corresponding sides are proportional:

  (2x +1)/5 = (x +2)/3

  3(2x +1) = 5(x +2) . . . . . cross multiply

  6x +3 = 5x +10 . . . . . . . eliminate parentheses

  x = 7 . . . . . . . . . . . . . . . subtract 5x+3 from both sides

Answer:

Circumference = 37.68

Area = 113.04

Step-by-step explanation:

Circumference = π × d

Circumference = 3,14 × 12 feet

Circumference = 37.68

Area = π × r²

Area = 3,14 × 6 × 6

Area = 113.04

Answer:

5351.2

Step-by-step explanation:

596 times 9 = 5364

64 divided by 5 = 12.8

5364 minus 12.8 = 5351.2

Answer:

  437.3 ft

Step-by-step explanation:

The angle of depression can be copied inside the triangle to the angle of elevation (at lower right). Then the side x can be seen to be adjacent to the angle.

The mnemonic SOH CAH TOA reminds you of the relations. Here, we have the hypotenuse and we want the adjacent angle. The relevant relation is ...

  Cos = Adjacent/Hypotenuse

  cos(29°) = x/(500 ft)

Multiplying by 500 ft gives ...

  x = (500 ft)cos(29°)

  x ≈ 437.3 ft

Additional comment

You have posted a number of problems that make use of this geometry. They are all solved the same way:

  a) identify the desired measure and the given measures

  b) using SOH CAH TOA, identify the relation applicable to those measures

  c) fill in the given values in the equation

  d) solve for the unknown

You may need to make use of what you know about angles and triangles in order to relate given angles to ones you need to use.

Answer:

B. 8 + 5

Step-by-step explanation:

5 - (-8)

= 5 + 8

= 8 + 5

Answer:

Step-by-step explanation:

(-1 - 5)/(0 + 3)= -6/3 = -2

y - 5 = -2(x + 3)

y - 5 = -2x - 6

y = -2x - 1

Answer:

choose "infinitely more solutions"

Step-by-step explanation:

Let's solve this system by substitution method

y+1=2x

- 1 = - 1

y = 2x -1   <-- sbstitute this in the next equation

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

    5y+5 = 10x

5(2x -1) + 5 = 10x

10x -5 + 5 = 10x

10x + 0= 10x

- 10x = -10x

0 = 0      <-- infinitely more solutions

Answer:

5+5=10x

B) 1 5/8 feet per hour is your answer

3/8foot=1/5hour

15foot =8hour

1 foot =8/15 hour

Answer:

4/5

Step-by-step explanation:

The ratio of girls to boys is 12/15. Since, there are 12 girls to the 15 boys in the classroom.

Then, you would simplify 12/15.

The simplified form of 12/15 is 4/5

Step-by-step explanation:

-8x+5 > 21

Minus 5 from both sides

-8x > 16

Then divide 8 from both sides (also I am pretty sure the sign would change because you are dividing by a negative number)

x < -2

So the answer is x is less than or equal to -2

or C

Answer:

[tex]V_2 = 583.67[/tex]

Step-by-step explanation:

Given

Represent the volume of the cylinder with V1 and the cone with V2.

So:

[tex]V_1 = 1751[/tex]

Required

Find V2

The volume of a cylinder is:

[tex]V_1 = \pi r^2h[/tex]

Because the cone and the cylinder have the same base area and height, the volume of the cone is:

[tex]V_2 = \frac{1}{3}\pi r^2h[/tex]

Substitute [tex]V_1[/tex] for [tex]\pi r^2h[/tex].

[tex]V_2 = \frac{1}{3}\pi r^2h[/tex]

[tex]V_2 = \frac{1}{3}V_1[/tex]

Substitute 1751 for V1

[tex]V_2 = \frac{1}{3} * 1751[/tex]

[tex]V_2 = \frac{1* 1751}{3}[/tex]

[tex]V_2 = \frac{1751}{3}[/tex]

[tex]V_2 = 583.67[/tex]

The volume of the cone is 583.67 cubic units
