Step-by-step explanation:

area of circle = pi * r^2

3.142 * 7^2 = area of the whole circle

as we only have 1/4 of the circle we divide our area by 4

(3.142 *7^2) / 4 = 38.4895

Answer:

38.4895

Step-by-step explanation:

basically you are finding a quarter of the area of the circle. So the formula is 1/4πr^2

so that's 3.142×7^2 and then divided by 4.

The table below shows the weights of Liam's pumpkin, l(w), and
Patricia's pumpkin, p(w), over a four-week period wherew represents
the number of weeks. Liam's pumpkin grows at a constant rate.
Patricia's pumpkin grows at a weekly rate of approximately 52%.
Assume the pumpkins continue to grow at these rates through week 13.
When comparing the weights of both Liam's and Patricia's pumpkins
in week 10 and week 13, which statement is true?
(1) Liam's pumpkin will weigh more in week 10 and week 13.
3) Patricia's pumpkin will weigh more in week 10 and week 13.
(3) Liam's pumpkin will weigh more in week 10, and Patricia's
pumpkin will weigh more in week 13.
4) Patricia's pumpkin will weigh more in week 10, and Liam's
pumpkin will weigh more in week 13.

Answers

Liam's pumpkin will weigh more in week 10, and Patricia's pumpkin will weigh more in week 13. Then the correct option is C.

What is the linear system?

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

The table below shows the weights of Liam's pumpkin, l(w), and Patricia's pumpkin, p(w), over a four-week period which represents the number of weeks.

Liam's pumpkin grows at a constant rate.

Patricia's pumpkin grows at a weekly rate of approximately 52%.

Let x be the number of the week and y be the weight in pounds.

The equation of Liam's pumpkin will be

[tex]\rm y - 2.4 = \dfrac{5.5-2.4}{7-6} (x- 6)\\\\y - 2.4 = 3.1(x- 6)\\\\y = 3.1x - 16.2[/tex]

Then the weight of Liam's pumpkin after 10 weeks will be

y = 3.1 × 10 - 16.2

y = 31 - 16.2

y = 14.8

Then the weight of Liam's pumpkin after 10 weeks will be

y = 3.1 × 13 - 16.2

y = 40.3 - 16.2

y = 24.1

The equation of Patricia's pumpkin will be

[tex]\rm y = a\times (1.52)^{x}[/tex]

For x = 6 and y = 2.5

Then

[tex]\rm 2.5 = a \times 1.52^6\\\\a \ \ = 0.203[/tex]

We have

[tex]\rm y = 0.203 \times (1.52)^{x}[/tex]

Then the weight of Patricia's pumpkin after 10 weeks will be

[tex]\rm y = 0.203 \times (1.52)^{10}\\\\y = 13.36[/tex]

Then the weight of Patricia's pumpkin after 13 weeks will be

[tex]\rm y = 0.203 \times (1.52)^{13}\\\\y = 46.93[/tex]

What two integers does sqrt41 fall between? explain reasoning

Answers

Answer:

Below!

Step-by-step explanation:

Given square root:

[tex]\sqrt41[/tex]

Let's note a few perfect square roots.

[tex]1 = \sqrt{1 \times 1} = \sqrt{1}[/tex]

[tex]2 = \sqrt{2 \times 2} = \sqrt{4}[/tex]

[tex]3 = \sqrt{3 \times 3} =\sqrt{9}[/tex]

[tex]4 = \sqrt{4 \times 4} =\sqrt{16}[/tex]

[tex]5 = \sqrt{5 \times 5} =\sqrt{25}[/tex]

[tex]6 = \sqrt{6 \times 6} =\sqrt{36}[/tex]

[tex]7 = \sqrt{7 \times 7} =\sqrt{49}[/tex]

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

And so on...

When looking at the perfect square roots we identified, we can say that:

[tex]\sqrt{36} < \sqrt{41} < \sqrt{49}[/tex]

Therefore,

[tex]6 < \sqrt{41} < 7[/tex]

We can conclude that [tex]\sqrt{41}[/tex] is between 6 and 7.

Let's check the squares of first 10 number

1²=12²=43²=94²=165²=256²=367²=498²=649²=8110²=100

41 lies between 36 and 49

If an investor has a $5,000 pretax return, the state tax rate is 4.5%, and the federal tax rate is 22.0%, what is the real investment value? $1,325 $3,675 $3,900 $4,775

Answers

Based on the given parameters, the real value of the investment is $3675

How to determine the value of the investment?

From the question, the given parameters about the investment are:

Pretax return = $5,000

State tax rate = 4.5%

Federal tax rate = 22.0%

The real value of the investment is calculated using the following formula

Real investment value = Pretax return - [(Pretax return * State tax rate) * Pretax return * Federal tax rate)]

Substitute the given values in the above equation.

Real investment value = 5000 - [(5000 * 4.5%) + (5000 * 22.0%)]

Evaluate the products

Real investment value = 5000 - [225 + 1100]

Evaluate the sum in the above equation

Real investment value = 5000 - 1325

Evaluate the difference in the above equation

Real investment value = 3675

Hence, the real value of the investment is $3675

One angle of a parallelogram measures 20 what are the measures of the other three angles in the parallelogram

Answers

Answer:

160°, 20° and 160°

[tex] \: [/tex]

Step-by-step explanation:

Let us assume A, B, C and D are the four angles of the parallelogram. Where, ∠A = 20° and we have to find the measure of ∠B, ∠C and ∠D

So, If ∠A = 20°, then So, also ∠C = 20°.

[Opposite angles of a parallelogram are equal to each other]

Therefore,

The measure of ∠C is 20°

⠀

And, ∠A and ∠B are adjacent angles. We know,

Sum of two adjacent angles = 180°

So,

⇒ ∠A + ∠B = 180°

⇒ 20° + ∠B = 180°

⇒ ∠B = 180° – 20°

⇒ ∠B = 160°

So,

The measure of ∠B = 160°

⠀

So, If ∠B = 160°, then So, also ∠D = 160°.

[Opposite angles of a parallelogram are equal to each other]

Therefore,

The measure of ∠D is 160°

The image shows a circle with center (4,6) and radius 10 units.

Answer:

A, B, D, E

Step-by-step explanation:

Every point is on the circle except for the middle one

The points lying on the circle will be (-4, 12), (-6, 6), and (4, 16). Then the correct options are A, B, and E.

What is the equation of a circle?

Let r be the radius of the circle and the location of the center of the circle be (h, k). Then the equation of the circle is given as,

(x - h)² + (y - k)² = r²

The center is at (4, 6) and the radius is 10 units. Then the equation of the circle is calculated as,

(x - 4)² + (y - 6)² = 10²

(x - 4)² + (y - 6)² = 100 .......1

Substitute (-4, 12) in equation 1, then we have

(-4 - 4)² + (12 - 6)² = 100

100 = 100

Substitute (-6, 6) in equation 1, then we have

(-6 - 4)² + (6 - 6)² = 100

100 = 100

Substitute (13, 10) in equation 1, then we have

(13 - 4)² + (10 - 6)² = 100

97 ≠ 100

Substitute (-4, 12) in equation 1, then we have

(4 - 4)² + (16 - 6)² = 100

100 = 100

If the equation is satisfied, then the point lies on the circle.

A simple random sample is drawn from a normally distributed population, and when making a statistical inference about the population mean, the margin of error is found to be 5.9 at a 95% level of confidence. if the mean of the sample is 18.7, what is the 95% confidence interval for the population mean? 18.7 ± 5.9 18.7 ± 9.7 18.7 ± 11.6 18.7 ± 15.2

Answers

If the mean of the sample is 18.7, The 95% confidence interval for the population mean is 18.7 ± 11.6.

Confidence interval

z-score for 95% confidence interval =1.96

Lower limit of the interval:

Lower limit=Sample mean-(Z-score×Margin of error)

Lower limit=18.7-(1.96×5.9)

Lower limit=18.7-11.564

Lower limit=18.7-11.6 (Approximately)

Upper limit of the interval:

Upper limit=Sample mean+(Z-score×Margin of error)

Upper limit=18.7+(1.96×5.9)

Upper limit=18.7+11.564

Upperr limit=18.7+11.6 (Approximately)

Hence:

Confidence interval= 18.7 ± 11.6

Therefore the 95% confidence interval for the population mean is 18.7 ± 11.6.
