if f (x)= x2- 2x : which of the following is the value of f (4)

Answer:

reflection-FLIP rotation- SPIN or

TURN

Step-by-step explanation:

Answer:

x = 110

y = 40

Step-by-step explanation:

m∡5 = 30° because it forms a linear pair with ∡6, which is 150°

x + y = 150  (angles 4 and 6 are alternate-interior and are congruent)

angles 3 and 6 are same-side interior and are supplementary

therefore:  x -2y = 180-150

if x + y = 150 we can say that x = 150 - y

we can plug '150-y' for 'x' in x - 2y = 30

150-y - 2y = 30

-3y = -120

y = 40

x = 110

Answer:

15 rounds

Step-by-step explanation:

Change 75% into a decimal (0.75).

Multiply 20 by 0.75.

When doing so, you get 15 rounds.

To check this: 15/20 = 3/4 = 0.75

if that student is scussordbhe then they won 15 rounds, if they arent they won 5.

Answer:

x = 50°

Step-by-step explanation:

the sum of the exterior angles of any polygon is 360°

2x-12 + 32 + 2x + x + 90 = 360

5x + 110 = 360

5x = 250

x = 50

Answer: X= 16.83 or 17 rounded

Answer:

The answers are:

The height is 6

The radius is 8

The volume is 128 π cubic units.

Step-by-step explanation:

The height is shown in the picture. So the first answer is 6.

To find the radius, you use the equation. [tex]\sqrt{slant height^{2}- height^{2} }[/tex] = radius

The slant height 10, and the height is 6. So you plug those into the equation and solve.

[tex]\sqrt{10^{2}-6^{2} }[/tex] =

[tex]\sqrt{100-36}[/tex] =

[tex]\sqrt{64}[/tex] = 8

So the radius is 8.

Now we use the equation [tex]\pi[/tex][tex]r^{2}[/tex] [tex]\frac{h}{3}[/tex] = volume.

[tex]\pi[/tex][tex]8^{2}[/tex] [tex]\frac{6}{3}[/tex] =

[tex]\pi[/tex]64 [tex]\frac{6}{3}[/tex] =

[tex]\pi[/tex] 64(2) = 128 [tex]\pi[/tex] cubic units

The statements about the cone is that,

The height is 6 units, the radius is 8 units and the volume is 128π cubic units.

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

Given a cone.

We have to find the complete the statements related to the cone.

From the figure,

height of the cone = 6 units

Using the Pythagoras theorem,

Radius of the cone = √(10² - 6²) = 8 units

Volume of the cone = 1/3 π r² h

                                 = 1/3 π × 8² × 6

                                 = 128π cubic units

Hence the height, radius and volume of the cone are 6 units, 8 units and 128π cubic units respectively.

10(a + 10) = 12 2

Applying the secant-tangent segment theorem, the equation that will result using the figure given is: C. 10(a + 10) = 12².

The secant-tangent segment theorem states that if a tangent and a secant intersect at a point outside a circle, then the square of the measure of the products of the secant segment and its external secant segment equals the square of the measure of the tangent segment.

Thus, using the figure given, the equation that results from applying the secant-tangent segment theorem would be: C. 10(a + 10) = 12²

Answer:

Step-by-step explanation:

12=3x-2y

2y+12=3x

2y=3x-12

y=(3x-12)/2

y=mx+b

To be parallel to the line above our line must have the same slope or m. The above line has a slope of 3/2 or 1.5 so the parallel line will be

y=1.5x+b, using point (7,10) we can solve for the y intercept or b

10=1.5(7)+b

10=10.5+b

b=-0.5 so our line is

Answer: Each person will pay $2.34.

Step-by-step explanation:

Given: Cost of one pound of cherries = $1.30

Cost of [tex]7\dfrac15[/tex] pounds of cherries  = [tex]7\dfrac15\times 1.30[/tex]

[tex]=\dfrac{36}{5}\times1.30[/tex]

= $9.36

Each person will pay = (Cost of [tex]7\dfrac15[/tex] pounds ) ÷ 4

[tex]=9.36\div4[/tex]

=$2.34

Hence, Each person will pay $2.34.
