of K(x) with the graph of f(x)?

Answer:

Step-by-step explanation:

450

Answer:

Step-by-step explanation:

(x+1)(x-3)(x-4) = (x+1)(x²-7x+12) = x³-6x²+5x+12

:::::

(x+3)(x-0)(x-0)(x-5) = (x+3)(x²)(x-5) = (x²-2x-15)x² = x⁴-2x³-15x²

:::::

(x+2)³ = x³ + 3·x²·2 + 3·x·2² + 2³ = x³ + 6x² + 12x + 8

:::::

(x+3)²(x+1) = (x²+6x+9)(x+1) =  x³ + 7x² + 15x + 9

Answer: See explanation

Step-by-step explanation:

Let the width of the rectangle be x.

The length of a rectangle is 3 times as big as the width. Length = 3x

New width = x + 4

New length = 3x + 4

The new area will be:

a = (3x + 4)(x + 4)

a = 3x² + 12x + 4x + 16

a = 3x² + 16x + 16

Answer:

-3.6 degrees

Step-by-step explanation:

Since we need to find the temperature that is 3 miles above ground we first need to multiply the distance above ground by the decrease in temperature per mile.

3 * 5.2 = 15.6

Now that we have the total decrease in temperature at that altitude we subtract it from the temperature at ground level. This gives us the final temperature at 3 miles above the ground.

12 - 15.6 = -3.6

Finally, we can see that the temperature is -3.6 degrees

Answer: 131 magazines per hour

Step-by-step explanation:

Peggy delivered 328 magazines in 2.5 hours.

To find out the rate at which she delivered these magazines, divide the number of magazines by the time taken to deliver them:

= Magazines / Time in hours

= 328 / 2.5

= 131 magazines per hour

Answer: x=20/3=6.67

Step-by-step explanation:

To solve proportions, the most useful way is to use [cross multiplication], where we not multiply horizontally but as diagonally.

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

Given

x:10=9:6

Cross Multiply

9·x=6·10

9x=60

Divide 9 on both sides

9x/9=60/9

x=20/3=6.67

Answer:

Radius is 3.5 cm

Diameter is 7 cm

Step-by-step explanation:

Radius is half the diameter

They give you the diameter at 7 cm

Then you have to half that to get 3.5 cm as the radius

Answer:

The answers are the diameter is 7 because whatever the line across is it's the diameter and the radios is half of what the diameter is so whatever is half of 7 is your radios.

Step-by-step explanation:

Diameter: 7

Radios: 3.5 or 3 1/2

Answer:

[tex]y=3x[/tex]

Step-by-step explanation:

[tex]Ax+By+C[/tex] ⇒ [tex]y=mx+b[/tex]

[tex]3x+y=0[/tex]

Since there are no coefficients on the [tex]y[/tex], you can convert the equation in one step.

Subtract [tex]3x[/tex] from both sides

[tex]y=3x+0[/tex] [tex]or[/tex] [tex]y=3x[/tex]

Answer:

C

Step-by-step explanation:

Method A:

270 decrease 25% =

270 × (1 - 25%) = 270 × (1 - 0.25) = 202.5

202.5 increase 6% =

202.5 × (1 + 6%) = 202.5 × (1 + 0.06) = 214.65

Method B:

270 increase 6% =

270 × (1 + 6%) = 270 × (1 + 0.06) = 286.2

286.2 decrease 25% =

286.2 × (1 - 25%) = 286.2 × (1 - 0.25) = 214.65

Step-by-step explanation:

total ratio is 5

first find the total amount

bob's ratio is 2/5

so 2/5 ×total amount=8 pounds

0.4 ×total amount=8 pounds

total amount=8/0.4=20 pounds

so chris receives: 20-8=12 pounds

Answer:

answer would be (1,-1)

Step-by-step explanation:

Dialation means to multiply, so u would multiply the point where D is so in the graph it shows D is on 2, -2 so you would multiply 2 by 1/2 and -2 by 1/2 which would give you (1, -1)

Answer:

14

Step-by-step explanation:

-4,-5

2,3

-4-2= -6

-5-3= -8

Answer:

  V = (2/3)(11)

Step-by-step explanation:

The given cylinder has a height of 2r, so its volume is ...

  V = πr²(2r) = 2πr³

The volume of a sphere is given by ...

  V = 4/3πr³

Then the ratio of the volume of the sphere to the volume of the cylinder is ...

  (4/3πr³)/(2πr³) = (4/3)/2 = 2/3

So, the volume of the sphere is 2/3 times the volume of the cylinder:

  V = (2/3)(11)

Answer:

48x - 32

General Formulas and Concepts:

Pre-Algebra

Algebra I

Step-by-step explanation:

Step 1: Define

8(6x - 4)

Step 2: Expand

Answer:

(x,y): (6 , -3) or (-30/7 , 33/7)

Step-by-step explanation:

6x + 8y = 12

x = y + 9 or   y = x+ 9

if x = y+9

6*(y+9) + 8y = 12

14y = -42

y = -3 and x = 6

if y = x+9

6x + 8*(x+9) = 12

14x = -60

x = -30/7   and y = 33/7

Answer:

D) 126 in²

Step-by-step explanation:

A rectangular prism is 3 inches long, 5 inches wide, and has a height of 6 inches. What is its surface area?

The formula for the surface area of a rectangular prism =

A=2(wl+hl+hw)

Where

W= Width = 5in

H = Height = 6 in

l = Length = 3 in

Surface area =

2(5 × 3 + 6 × 3 + 5 × 6) square inches

2(15 + 18 + 30) square inches

2(63) square inches

= 126 square inches (in²)

Answer:

d. V = 668.2 ft³

Step-by-step explanation:

[tex]V = \frac{1}{2}bhl\\V = \frac{1}{2}(8.6)(8.4)(18.5)\\V = 668.2ft^{3}[/tex]

Answer:

[tex]\boxed {\boxed {\sf D. \ V \approx 668.2 \ ft^3}}[/tex]

Step-by-step explanation:

The volume of a triangular prism is found using this formula:

[tex]V=\frac{1}{2} bhl[/tex]

For this prism, the base is 8.6 feet, the height is 8.4 feet, and the length is 18.5 feet.

[tex]b= 8.6 \ ft \\h= 8.4 \ ft \\l= 18.5 \ ft[/tex]

Substitute the values into the formula.

[tex]V= \frac{1}{2} (8.6 \ ft) (8.4 \ ft) ( 18.5 \ ft)[/tex]

Multiply the first two numbers in parentheses.

[tex]V= \frac{1}{2} (72.24 \ ft^2) ( 18.5 \ ft)[/tex]

Multiply again.

[tex]V= \frac{ 1}{2} (1336.44 \ ft^3)[/tex]

Multiply by 1/2 or divide by 2.

[tex]V= 668.22 \ ft^3[/tex]

Round to the nearest tenth. The 2 in the hundredth place tells us to leave the 2 in the tenth place.

[tex]V \approx 668.2 \ ft^3[/tex]

The volume is about 668.2 cubic feet.

Answer:

30³÷(−5) = -6y²

Step-by-step explanation:

We need to find the value of the given expression :

30³÷(−5)

It can be written as :

[tex]\dfrac{30xy^3}{(-5xy)}=\dfrac{30}{-5}\times \dfrac{xy^3}{xy}\\\\=-6\times y^2\\\\=-6y^2[/tex]

So, the value of the given expression is [tex]-6y^2[/tex].
