The peak of the cylinder is about 9 yards.

Explanation:

From the above question,

They have given:

     A cylinder with a diameter of 8 yards has a volume of 452.16 yd³.

Here we need to find what is the height of the cylinder

Here,

       [tex]\pi = 3.14[/tex]. 44 yards 11 yards 8 yards 3 yards

To locate the radius of the cylinder, which is half of of the diameter.

        [tex]\text{radius = 8 yards} \div \text{2}[/tex]

        [tex]\text{radius} = 4 \ \text{yards}[/tex]

Then we can use the formulation for the quantity of a cylinder to locate the height:

       [tex]\text{volume} = \pi \times \text{radius} \times \text{height}[/tex]

       [tex]452.16 = 3.14 \times 4^2 \times\text{height}[/tex]

       [tex]452.16 = 50.24 \times \text{height}[/tex]

       [tex]\text{height} = 452.16 \div 50.24[/tex]

       [tex]\text{height} = 9 \ \text{yards}[/tex]

Therefore, the peak of the cylinder is about 9 yards.

The solution to the interest rate problems from part I to part VI can be found below.

Part I:

Part II:

Part III:

Interest = P * ((1 + r/n)^(n*t) - 1)

where P is the principal (in this case, $2500), r is the interest rate per year (0.1799), n is the number of times the interest is compounded per year (365), and t is the time in years (1).

Interest = 2500 * ((1 + 0.1799/365)^(365*1) - 1) = $449.23

Part IV:

If the APR had been 17.99%, compounded daily, for the whole year, the effective interest rate would be the same as the APR, since there is no introductory 0% period.

Effective annual interest rate = 17.99%

Part V:

Part VI:

As calculated in Part I, the interest Oliver would accrue during the first 90 days with the 17.99% APR is $33.53. Since the 0% APR for the first 90 days means he will not accrue any interest during that time, the 0% APR will save him $33.53 in interest.

The area of the shaded region is evaluated to be equal to the expression 24z² - 22z + 3

To get the area of the shaded region, we subtract the area of the small square from the area of the bigger square as follows:

area of bigger square = (5z - 2)(5z - 2)

area of bigger square = 25z² - 20z + 4

area of small square = (z + 1)(z + 1)

area of bigger square = z² + 2z + 1

area of the shaded region = 25z² - 20z + 4 - (z² + 2z + 1)

area of the shaded region = 25z² - 20z + 4 - z² - 2z - 1

area of the shaded region = 24z² - 22z + 3

[tex]4\times 724 = 2,900[/tex]

[tex]31,900 - 2,900 = 29,000[/tex]

That's the constant.

So,

[tex]f(n) = 725n + 29,000[/tex]

Final outcome is: 1 quart, 2 cups. 2 quarts, 1 pint, and 2 cups are the outcome of removing 1 quart, 2 pints, and 1 cup from 3 quarts and 1 pint.

We must convert all the units to the same level of measurement in order to remove these two mixed volume units. We are aware that 2 pints and 2 cups equal 1 quart. In order to subtract the volumes, we can convert the pint and cup units to quarts.

We begin by converting 1 pint to quarts:

Pints equal half quarts.

The next step is to convert 1 cup to quarts:

1/4 pint is equal to one cup.

Hence, the second mixed unit is:

1.75 quarts are equal to 1 quart, 2 pints, and 1 cup (1 + 2(1/2) + 1/4).

We may now take the volumes away:

3 quarts and a pint minus a pint, a cup, and a quart equals 3 + 1/2 minus 1.75 to 2.75 quarts.

This result can be written as a whole number of quarts plus any leftover pints and cups to return it to mixed units. Since a quart is equal to two pints, we can write:

2.75 quarts equal 2 quarts plus a half-quart.

We may convert the remaining 1/2 quart to pints because 2 cups equal 1 pint:

2 pints from a half-quart

The end result is as a result:

1 quart, 2 cups

Therefore, 2 quarts, 1 pint, and 2 cups are the outcome of removing 1 quart, 2 pints, and 1 cup from 3 quarts and 1 pint.

Answer: 2.43082 & 20.56918

Step-by-step explanation: The two numbers with the product of -50 and the sum of 23 are the numbers in the answer box.

Probability that fewer than 129 people in a random sample of 300 did not use the top web browser is approximately 0.0564 for z value.

We must use the normal approximation to the binomial distribution to determine the likelihood that less than 129 individuals in a random sample of 300 persons did not use the most popular web browser. The number of successes in a fixed number of independent trials with the same chance of success in each trial is modelled using the binomial distribution.

Secondly, based on the market share of 51.85%, we must determine the anticipated proportion of 300 participants who did not use the leading web browser:

Estimated percentage of users not using the most popular web browser: 300 * (1 - 0.5185) = 143.55

The standard deviation of the number of participants in a sample of 300 who didn't use the most popular web browser needs to be calculated next:

Standard deviation =[tex]\sqrt{(300 * 0.5185 * 0.4815)}[/tex] = 9.16

We must compute the z value for this value in order to determine the likelihood that fewer than 129 persons did not use the most popular web browser:

z = (129 - 143.55) / 9.16 = -1.59

The probability of a z-score smaller than -1.59 is 0.0564, according to a basic normal distribution table or calculator.

Hence, there is a 0.0564 percent chance that less than 129 out of 300 randomly selected participants did not utilize the most popular web browser.

Step-by-step explanation:

csc(x) = 1/sin(x)

We know that sin(-x) = -sin(x), so we can rewrite csc(-176°) as:

csc(-176°) = 1/sin(-176°) = -1/sin(176°)

Now, we need to find sin(176°) without a calculator. We can use the fact that the sine function has period 360°:

sin(x) = sin(x - 360°)

Therefore, we can subtract 360° from 176° until we get an angle between 0° and 360°:

176° - 360° = -184° + 360° = 176° - 360° = -184° + 360° = ...

We can continue this process until we get an angle between 0° and 360°. Notice that after each subtraction of 360°, the sine function is negated:

sin(176°) = -sin(-184°) = sin(176° - 360°) = -sin(-184° + 360°) = ...

We can continue this process until we get an angle between 0° and 360°:

sin(176°) = -sin(-184°) = sin(176° - 360°) = -sin(-184° + 360°) = sin(176° - 720°) = -sin(-544°) = sin(544°)

Now, we need to find the sine of 544°, which is equivalent to the sine of 544° - 360° - 360° = -176°. We know that sin(-x) = -sin(x), so:

sin(544°) = -sin(-176°) = sin(176°)

Therefore:

csc(-176°) = -1/sin(176°)

Now, we can use the fact that sin^2(x) + cos^2(x) = 1 to find cos(176°):

sin^2(176°) + cos^2(176°) = 1

cos^2(176°) = 1 - sin^2(176°)

cos(176°) = ±sqrt(1 - sin^2(176°))

Since 0° ≤ 176° ≤ 180°, the cosine function is negative:

cos(176°) = -sqrt(1 - sin^2(176°))

Substituting this into the formula for csc(-176°), we get:

csc(-176°) = -1/sin(176°) = -1/(-sqrt(1 - cos^2(176°))) ≈ -17.204

Therefore, the value of csc(-176°) to the nearest thousandth is -17.204.

Answer:

To find the average (also known as the arithmetic mean) of the data values, we need to divide the sum of the values by the number of values. We are given the sum of 12 data values, which is 942. So:

Average = Sum of values / Number of values

Average = 942 / 12

We can simplify this by dividing both the numerator and denominator by their greatest common factor, which is 6:

Average = (942 ÷ 6) / (12 ÷ 6)

Average = 157 / 2

Average = 78.5

Therefore, the average of the 12 data values is 78.5.

Answer: We can use the fact that the sine function is an odd function, which means that:

sin(-x) = -sin(x)

So, we have:

sin(-15 degrees) = -sin(15 degrees)

We can use the sum and difference identity for sine, which states that:

sin(a - b) = sin(a)cos(b) - cos(a)sin(b)

Letting a = 45 degrees and b = 30 degrees, we get:

sin(45 degrees - 30 degrees) = sin(45 degrees)cos(30 degrees) - cos(45 degrees)sin(30 degrees)

We can use the fact that cos(45 degrees) = sin(45 degrees) = √2 / 2 and cos(30 degrees) = √3 / 2 and sin(30 degrees) = 1 / 2 to simplify:

sin(15 degrees) = (√2 / 2)(√3 / 2) - (√2 / 2)(1 / 2)

sin(15 degrees) = (√6 - √2) / 4

Therefore, we have:

sin(-15 degrees) = -sin(15 degrees) = -[(√6 - √2) / 4] = (-√6 + √2) / 4

So the exact value of sin(-15 degrees) is (-√6 + √2) / 4.

Answer:

Using the Pythagorean theorem, we know that in a right-angle triangle, we have:

a^2 + b^2 = c^2

where c is the hypotenuse.

From the given information, we have:

ab = 11 - x

a = x

b = 11

c = 11 (given)

We can use the given values to eliminate a or b from the Pythagorean theorem:

a^2 + (11 - x)^2 = 11^2

Expanding and simplifying, we get:

a^2 + 121 - 22x + x^2 = 121

a^2 + x^2 - 22x = 0

Substituting a = x into the above equation, we get:

x^2 + x^2 - 22x = 0

2x^2 - 22x = 0

2x(x - 11) = 0

So, either x = 0 or x - 11 = 0.

Since x cannot be zero (as it represents a length), we have x - 11 = 0.

Therefore, x = 11.

Hence, the value of x in its simplest form with a rational denominator is 11/1 or just 11.

Step-by-step explanation:

The given right triangle is an isosceles right triangle since its legs are equal in length (denoted by the tick marks).

Side x is the hypotenuse of the isosceles right triangle.

Given both legs are 11 units in length, we can use Pythagoras Theorem to calculate the length of the hypotenuse.

[tex]\boxed{\begin{minipage}{9 cm}\underline{Pythagoras Theorem} \\\\$a^2+b^2=c^2$\\\\where:\\ \phantom{ww}$\bullet$ $a$ and $b$ are the legs of the right triangle. \\ \phantom{ww}$\bullet$ $c$ is the hypotenuse (longest side) of the right triangle.\\\end{minipage}}[/tex]

As a and b are the legs, and c is the hypotenuse, substitute the following values into the formula and solve for x:

Therefore:

[tex]\implies 11^2+11^2=x^2[/tex]

[tex]\implies 121+121=x^2[/tex]

[tex]\implies 242=x^2[/tex]

[tex]\implies x^2=242[/tex]

[tex]\implies \sqrt{x^2}=\sqrt{242}[/tex]

[tex]\implies x=\sqrt{242}[/tex]

To simplify the radical, rewrite it as a product of prime numbers:

[tex]\implies x=\sqrt{11^2 \cdot 2}[/tex]

[tex]\textsf{Apply the radical rule:} \quad \sqrt{ab}=\sqrt{a}\sqrt{b}[/tex]

[tex]\implies x=\sqrt{11^2}{\sqrt{2}[/tex]

[tex]\textsf{Apply the radical rule:} \quad \sqrt{a^2}=a, \quad a \geq 0[/tex]
