A sprinkler that sprays water in a circular area can spray up to a radius of 22ft what is the maximum area of lawn that can be watered by the sprinkler use 3.14 to approximate date for Pie enter your answer as a decimal rounded to the nearest tenth in the Box
[ ] ft^2
To find the maximum area of the lawn that can be watered by the sprinkler, we can use the formula for the area of a circle:
A = πr^2
Given that the radius of the sprinkler's spray is 22ft, we can substitute this value into the formula:
A = 3.14 * (22)^2
A ≈ 3.14 * 484
A ≈ 1519.76
Rounded to the nearest tenth, the maximum area of the lawn that can be watered by the sprinkler is approximately 1519.8 ft^2.\(\huge{\mathcal{\colorbox{black}{\textcolor{lime}{\textsf{I hope this helps !}}}}}\)

a telecommunications company provided its cable tv subscribers with free access to a new sports channel for a period of 1 month. it then chose a sample of 405 television viewers and asked them whether they would be willing to pay an extra $10 per month to continue to access the channel. a total of 27 of the 405 replied that they would be willing to pay. the marketing director of the company claims that more than 6% of all its subscribers would pay for the channel. can you conclude that the director's claim is true? use the a
The company may need to reconsider its decision to charge extra for the sports channel or come up with better marketing strategies to promote it.
Based on the given information, we can use statistical inference to determine whether the marketing director's claim is true or not. The sample size of 405 is sufficiently large enough for us to use the normal distribution to calculate the confidence interval. Firstly, we need to calculate the sample proportion of viewers who are willing to pay for the sports channel, which is given as 27/405 = 0.0667 (rounded to 4 decimal places). We can then calculate the standard error of the proportion using the formula SE = sqrt[p(1-p)/n], where p is the sample proportion and n is the sample size. Substituting the values, we get SE = sqrt[(0.0667 x 0.9333)/405] = 0.0161 (rounded to 4 decimal places). Next, we can calculate the 95% confidence interval using the formula CI = p ± Z*SE, where Z is the Z-score corresponding to the desired confidence level. For a 95% confidence level, Z = 1.96. Substituting the values, we get CI = 0.0667 ± 1.96 x 0.0161, which gives us a confidence interval of (0.0357, 0.0977) (rounded to 4 decimal places). Since the confidence interval does not include the marketing director's claim of more than 6%, we can conclude that there is not enough evidence to support the director's claim. In fact, the lower bound of the confidence interval suggests that only 3.57% of subscribers may be willing to pay for the channel, which is significantly lower than the claim. Therefore, the company may need to reconsider its decision to charge extra for the sports channel or come up with better marketing strategies to promote it.

The volume of the pyramid is approximately 5.9 cm³.
What is the volume of pyramid?To find the volume of a pyramid with a square base, you can use the formula:
Volume = (1/3) * base area * height
First, let's find the area of the square base. The perimeter of the base is given as 5.7 cm, which means each side of the square has a length of 5.7 cm / 4 = 1.425 cm.
The area of a square is given by the formula:
Area = side length * side length
Substituting the side length, we have:
Area = 1.425 cm * 1.425 cm = 2.030625 cm²
Now, we can calculate the volume of the pyramid:
Volume = (1/3) * base area * height
= (1/3) * 2.030625 cm² * 8.6 cm
= 5.91834375 cm³
Rounding to the nearest tenth of a cubic centimeter, the volume of the pyramid is approximately 5.9 cm³.

The value of the variables for which ABCD must be a parallelogram include the following:
x = 4.
y = 5.
How to determine value of the variables for ABCD?In order for any quadrilateral to be considered as a parallelogram, two pairs of its parallel sides must be equal (congruent). This ultimately implies that, the diagonals of a parallelogram would bisect one another only when their midpoints are the same:
Line segment AC = Line segment BD
Next, we would write an equation to model the length of the diagonals of this parallelogram as follows;
4x - 2 = 3y - 1 .........equation 1.
3y - 3 = 3x .........equation 2.
From equation 2, we have the following:
y - 1 = x .........equation 3.
By substituting equation 3 into equation 1, we have:
4(y - 1) - 2 = 3y - 1
4y - 4 - 2 = 3y - 1
4y - 3y = 6 - 1
y = 5.
For the value of x, we have:
x = y - 1
x = 5 - 1
x = 4

Step-1 : Multiply the coefficient of the first term by the constant 1 • -16 = -16
Step-2 : Find two factors of -16 whose sum equals the coefficient of the middle term, which is 6 .
-16 + 1 = -15
-8 + 2 = -6
-4 + 4 = 0
-2 + 8 = 6 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -2 and 8
p2 - 2p + 8p - 16
Step-4 : Add up the first 2 terms, pulling out like factors :
p • (p-2)
Add up the last 2 terms, pulling out common factors :
8 • (p-2)
Step-5 : Add up the four terms of step 4 :
(p+8) • (p-2)
Which is the desired factorization
Answer:
p = 8
Step-by-step explanation:
64 = 4(p+2) + 24
64 = 4p + 8 + 24
64 = 4p + 32
32 = 4p
I substracted 32 from 64, and 32 deletes him self
8
I divided 32 by 4, and the 4p deletes himself

A sum of money is divided among three girls, Rheanna, Kerisha and Anne, in the ratio 2:3:7, respectively. If Anne gets $15
more than Kerisha, what is the value of the total sum that was shared?
Using proportions, it is found that the value of the total sum that was shared was of $45.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Considering the rates, Anne's and Kerisha's proportions, out of the total value N, are given by:
\(A = \frac{7}{2 + 3 + 7}N = \frac{7N}{12}\)\(K = \frac{3}{2 + 3 + 7}N = \frac{3N}{12}\)The difference is of $15, hence:
\(A - K = 15\)
\(\frac{7N}{12} - \frac{3N}{12} = 15\)
\(\frac{4N}{12} = 15\)
\(\frac{N}{3} = 15\)
N = 15 x 3 = 45

8r6s3 - 5r5s4 + r4s5 + 5r3s6
The difference of the polynomials (8r^6s^3 - 9r^5s^4 + 3r^4s^5) - (2r^4s^5 - 5r^3s^6 - 4r^5s^4) simplifies to 8r^6s^3 - 5r^5s^4 + r^4s^5 + 5r^3s^6.
To find the difference of the given polynomials, we subtract the second polynomial from the first polynomial term by term.
(8r^6s^3 - 9r^5s^4 + 3r^4s^5) - (2r^4s^5 - 5r^3s^6 - 4r^5s^4)
Removing the parentheses and combining like terms, we get:
8r^6s^3 - 5r^5s^4 + r^4s^5 + 5r^3s^6
Therefore, the difference of the polynomials is 8r^6s^3 - 5r^5s^4 + r^4s^5 + 5r^3s^6. This is the simplified form of the polynomial expression obtained by subtracting the second polynomial from the first polynomial.

An airplane leaves an airport and flies due west 150 miles and then 170 miles in the direction S 49.17°W. How far is the plane from the airport (round to the nearest mile)? (2 points) PLEASE HELP ASAP 30 POINTS!!!!!!! need full explanation and work
Answer:
299.99 miles
Step-by-step explanation:
Since the plane traveled due west,
The total angle is 49.17 + 90
Represent that with θ
θ = 49.17 + 90
θ = 139.17.
Represent the sides as
A = 170
B = 150
C = unknown
Since, θ is opposite side C, side C can be calculated using cosine formula as;
C² = A² + B² - 2ABCosθ
Substitute values for A, B and θ
C² = 150² + 170² - 2 * 150 * 170 * Cos 139.17
C² = 22500 + 28900 - 51000 * Cos 139.17
C² = 51400 - 51000 (−0.7567)
C² = 51400 + 38,591.7
C² = 89,991.7
Take Square Root of both sides
C = 299.9861663477167
C = 299.99 miles (Approximated)
Hence, the distance between the plane and the airport is 299.99 miles
Mr. Patterson goes to the redwoods in California. He sees a tree a tree that is 300 feet tall. The angle of elevation from the ground where Mr. Patterson is standing to the top of the tree is 75 degrees. How far away is Mr. Patterson standing from the tree? Round to the nearest tenth.
Using trigonometric functions, Mr. Patterson is standing approximately 68.2 feet away from the tree.
What are trigonometric functions?Trigonometric functions are mathematical functions that relate the angles of a right triangle to the lengths of its sides. There are 6 trigonometric functions and those are sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot).
The sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse. The cosine of an angle is defined as the ratio of the length of the adjacent side to the length of the hypotenuse. The tangent of an angle is defined as the ratio of the length of the opposite side to the length of the adjacent side.
Now,
We can use trigonometry to find the distance between Mr. Patterson and the tree. Let's call this distance "x".
In a right triangle with the tree as the hypotenuse, the opposite side is the height of the tree (300 feet), and the angle opposite the opposite side is 75 degrees. Therefore, we can use the tangent function to find the adjacent side, which is the distance Mr. Patterson is standing from the tree:
tan(75°) = opposite / adjacent
tan(75°) = 300 / x
x = 300 / tan(75°)
x ≈ 68.2
Therefore, Mr. Patterson is standing approximately 68.2 feet away from the tree.
