Given f(x)= 3x-5 find f (x-2)

To find the length of the radius, use the formula for the circumference of a circle. Divide the circumference by 2π to get the radius. In this case, the radius is approximately 59 cm.

In order to find the length of the radius, we can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. We are given that the circumference is 367 cm, so we can plug in the values to solve for r.

367 = 2πr

To isolate r, divide both sides of the equation by 2π: r = 367 / (2π)

Using a calculator to approximate π as 3.14, we can calculate the radius: r ≈ 367 / (2 * 3.14) ≈ 58.598

Therefore, the length of the radius, rounded to the nearest centimeter, is approximately 59 cm.

Answer:

Part 1) The volume of the prism is 3 times greater than the volume of the pyramid

Part 2) The prism would fill only one-third

Part 3) The cylinder and the cone

Step-by-step explanation:

Part 1) How do their volumes compare?

we know that

The volume of a rectangular prism is equal to

[tex]Vprism=BH[/tex]

where

B is the area of the base of rectangular prism

H is the height of the prism

The volume of a rectangular pyramid is equal to

[tex]Vpyramid=\frac{1}{3}BH[/tex]

where

B is the area of the base of rectangular pyramid

H is the height of the pyramid

Compare the volumes

[tex]Vprism=BH[/tex] -----> equation A

[tex]Vpyramid=\frac{1}{3}BH[/tex] -----> equation B

substitute equation A in equation B

[tex]Vpyramid=\frac{1}{3}Vprism[/tex]

[tex]Vprism=(3)Vpyramid[/tex]

The volume of the prism is 3 times greater than the volume of the pyramid

Part 2) If the pyramid was full of water, how much of the prism would it fill up?

Remember that

[tex]Vpyramid=\frac{1}{3}Vprism[/tex]

therefore

The prism would fill only one-third

Part 3) Name another pair of three-dimensional objects that have a relationship similar to this

we have the cylinder and the cone

The volume of the cylinder is equal to

[tex]Vcylinder=\pi r^{2}h[/tex]

The volume of the cone is equal to

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

Compare the volumes

[tex]Vcylinder=(3)Vcone[/tex]

The volume of the cylinder is 3 times greater than the volume of the cone

The volume of the pyramid is one-third of the volume of the rectangular prism with the same base and height. Therefore, if the pyramid was full of water, it would fill one-third of the prism. Cones and cylinders with the same base and height have a similar volume relationship.

When comparing the volumes of a rectangular pyramid and a rectangular prism that have the same base and the same height, the volume of the pyramid is exactly one-third the volume of the prism. This is because the volume of the prism is calculated by length × width × height, while the volume of the pyramid is ⅓ x (base area) x height, which is ⅓ x (length × width) x height.

If the pyramid was full of water, it would fill up exactly one-third of the prism. This corresponds to the geometric rule that says the volume of a pyramid is one-third the volume of a prism with the same base and height.

Another pair of three-dimensional objects with a similar relationship is a cone and a cylinder. Like the pyramid and prism, if the cone and cylinder have the same base and height, the cone's volume is one-third of the cylinder's volume.

Answer:

6%

Step-by-step explanation:

To solve this you need to subtract 607000 by 572000 to see how many people in the population decreased.

607,000- 572,000= 35,000

Then you put 35,000 over 607,000

also you need x over 100

35000/607,000 x/100

Then do cross product property

35,000*100=3,500,000

607,000* x= 607,000x

3,500,000= 607,000x

Then do 3,500,000 divided by 607,000

You get 5.76%

Round to the nearest percent and get 6%

Final answer:

The rate of decrease of the population from the 2000 census to the 2010 census is 6% when rounded to the nearest percent.

Explanation:

To calculate the rate of decrease of the city's population, we use the population values from the 2000 and 2010 censuses. The population in 2000 was 607,000, and in 2010 it was 572,000. To find the population decrease, subtract the 2010 population from the 2000 population:

Population decrease = Population in 2000 - Population in 2010

Population decrease = 607,000 - 572,000

Population decrease = 35,000

Next, to find the rate of decrease as a percent, we divide the population decrease by the original population (in 2000) and then multiply by 100:

Rate of decrease (%) = (Population decrease / Population in 2000) × 100

Rate of decrease (%) = (35,000 / 607,000) × 100

Rate of decrease (%) = 0.0577 × 100

Rate of decrease (%) = 5.77%

Round this to the nearest percent, and you get a 6% decrease.

Answer: 0.4521 - 0.4879

Step-by-step explanation:

1) Find the standard deviation with the given information:

n=3000

p=47% ⇒ 0.47

1-p= 1 - 0.47 = 0.53

[tex]\sigma =\sqrt{\dfrac{p(1-p)}{n}}\\\\\\.\ =\sqrt{\dfrac{0.47(0.53)}{3000}}\\\\\\.\ =\sqrt{\dfrac{0.2491}{3000}}\\\\\\.\ =\sqrt{0.00008303}\\\\\\.\ =0.009112[/tex]

2) Find the margin of error (ME) with the given information:

C=95% ⇒ Z = 1.960

σ=0.009112

ME = Z × σ

= 1.96 (0.009112)

= 0.01786

3) Find the confidence interval with the given information:

p = 0.47

ME = 0.01786

CI = p ± ME

= 0.47 ± 0.01786

= (0.4521, 0.4879)

Answer:

[ - 5, 3 ]

Step-by-step explanation:

Solve (x - 3)(x + 5) = 0

The zeros are x = - 5 and x = 3

These divide the domain into 3 intervals

(- ∞, - 5 ], [- 5, 3 ], [ 3, + ∞ )

Choose a test point in each interval and consider the sign of the result.

x = - 10 : (- 10 - 3)(- 10 + 5) = (- 13)(- 5) = 65 > 0

x = 0 : (0 - 3)(0 + 5) = (- 3)(5) = - 15 < 0 ← required result

x = 5 : (5 - 3)(5 + 5) = (2)(10) = 20 > 0

The solution is [ - 5, 3 ] or - 5 ≤ x ≤ 3

2:1  win / loss ratio

1 = 4 loses

4 x 2 = 8

the team has 6 wins it would need to win a total of 8 to have a 2:1 ratio

The baseball team must win 2 more games to achieve a win:loss ratio of 2:1, assuming they have no additional losses.

The student's baseball team currently has a record of 6 wins to 4 losses. The question asks how many more games the team must win to achieve a win:loss ratio of 2:1, assuming no more losses occur. To achieve a 2:1 win:loss ratio, the number of wins must be twice the number of losses. Since the losses are fixed at 4, the team needs 2 times 4 (which equals 8) wins to attain this ratio. The team has already won 6 games, so they need 8 - 6, which equals 2 more wins to reach a 2:1 ratio.

Step-by-step explanation:

The 10 part of the ratio represents 120 chickens. Divide 120 by 10 to find the value of one part of the ratio.

120 ÷ 10 = 12 ← value of 1 part of the ratio, hence

3 parts = 3 × 12 = 36 ← number of horses

The number of horses on the farm is​ 36.

Given that, the ratio of chicken to pigs to horses on a farm is 10:2:3 and the number of chickens on the farm is 120.

Ratio, in math, is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another.

We can write the given ratio 10:2:3 as 10x: 2x: 3x.

So, 10x=120

⇒x=12

Then, the number of horses=3x=36

Therefore, the number of horses on the farm is​ 36.

To determine how many 3/4 pound bags of peanuts can be made from a 5 pound bag, divide the weight of the 5 pound bag by the weight of each 3/4 pound bag.Therefore, 20/3 or 6 and 2/3 3/4 pound bags of peanuts can be made from a 5 pound bag.

Explanation:

To determine how many 3/4 pound bags of peanuts can be made from a 5 pound bag, we need to divide the weight of the 5 pound bag by the weight of each 3/4 pound bag. We can use the division operation to solve this.

5 pounds ÷ 3/4 pounds = 5 ÷ 3/4

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 3/4 is 4/3.

5 ÷ 3/4 = 5 × 4/3 = 20/3

Therefore, 20/3 or 6 and 2/3 3/4 pound bags of peanuts can be made from a 5 pound bag.

Answer:

A

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 4, - 4) and (x₂, y₂ ) = (4, 0) ← 2 points on the line

m = [tex]\frac{0+4}{4+4}[/tex] = [tex]\frac{4}{8}[/tex] = [tex]\frac{1}{2}[/tex]

Using (a, b) = (- 4, - 4), then

y - (- 4) = [tex]\frac{1}{2}[/tex] (x - (- 4)), that is

y + 4 = [tex]\frac{1}{2}[/tex] (x + 4) → A

Answer:

Step-by-step explanation:

Rewrite 2x-5y< 15 as follows:  Add 5y to both sides.  Then 2x < 15 + 5y.

Next, subtract 15 from both sides:  2x - 15 < 5y.

Finally, divide all terms by 5:           (2/5)x - 3 < y

Now find the y-intercept of this line.  Let x = 0.  Then y = -3.  Plot (0, -3) on graph paper.  Now, starting at (0, -3), move your pencil point 5 spaces to the right and 2 spaces up.  Plot this new point, (5, -1).  Now draw a dashed line through both (0, -3) and (5, -1).  Shade the area ABOVE this dashed line.
