Step-by-step explanation:

The sum of the lengths of the two shorter sides is 100 inches is the maximum area of the right triangle is: A(50) = 50(50) - (1/2)(50²) = 1250 square inches

We are given that the sum of the lengths of the two shorter sides of a right triangle is 100 inches. Let these lengths be x and y such that x < y. Then, the length of the hypotenuse z of the right triangle is given by the Pythagorean theorem, which states that:z² = x² + y²It follows that z = √(x² + y²)

The area A of the right triangle is given by:A = (1/2) * x * yTherefore, we want to maximize A subject to the constraint x + y = 100 and x < y. We can solve for y in terms of x as follows:y = 100 - xWe can now express the area A in terms of x as follows:A(x) = (1/2) * x * (100 - x)A(x) = 50x - (1/2)x²

The area is a parabolic function of x with a maximum value at the vertex of the parabola. The x-coordinate of the vertex is given by:x = -b/2a = -50/-1 = 50Therefore, the maximum area of the right triangle is:A(50) = 50(50) - (1/2)(50²) = 1250 square inches

Note that the lengths of the shorter sides of the right triangle are x = 50 inches and y = 50 inches, which makes the length of the hypotenuse z = √(50² + 50²) = √5000 = 50√2 inches.

Answer:

665.1

Step-by-step explanation:

The formula for an area of a hexagon is \(\frac{3\sqrt{3}}{2}S^{2}\)

the S (side) is 16 so,

\(\frac{3\sqrt{3}}{2}16^{2}\)

=\(\frac{3\sqrt{3} }{2}256\)

=\(3\sqrt{3}\) × 128

= \(384\sqrt{3}\)

round to the nearest sq. rt. means that you have to round to the nearest tenth, or 0.1

\(384\sqrt{3}\) is 665.10751 as a decimal

665.1 as rounded. Therefore, the area of the hexagon is 665.1 sq ft

Answer:

201 miles.

Step-by-step explanation:

If you've traveled 124 miles in 2 hours, than in one hour must've been 62 miles. 62 multiplied by 3 is 186, which is how much miles have been traveled in 3 hours. Plus the 15 minutes would probably be 201 miles. Hope this helps!

This statement is true, as the test statistic represents the number of standard deviations between the observed sample proportion and the claimed value (po) under the null hypothesis.

- The large value of the test statistic means that our observed data are not surprising when the null hypothesis is true. This statement is false. A large test statistic implies that the observed data is surprising when the null hypothesis is true, which means there is evidence against the null hypothesis.
- The researcher should fail to reject the null hypothesis. This statement is false. A large test statistic suggests evidence against the null hypothesis, so the researcher should reject the null hypothesis in favor of the alternative hypothesis.

- When the null hypothesis is true, the test statistic comes from a standard normal distribution. This statement is true, as the test statistic follows a standard normal distribution when the null hypothesis is true.
- There is a 4.318% chance that the alternative hypothesis is true. This statement is false. The test statistic does not directly provide the probability of the alternative hypothesis being true. Instead, we can use the test statistic to calculate the p-value, which represents the probability of obtaining a test statistic as extreme as the observed one, assuming the null hypothesis is true.

The element is remaining 146.6 grams after 7 minutes, to the nearest 10th of a gram.

An exponential function's curve is created by a pattern of data called exponential decay, which exhibits higher decreases over time.

The exponential decay function:

Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.

Given:

An element with mass 630 grams decays by 18.8% per minute.

That means, 18.8% = 0.188

Here, we will use the exponential decay function.

Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.

Here,

A₀ = 630 grams

r = 0.188

x = 7 minutes

Substituting the values to the formula,

A₇ = 630(1-0.188)⁷

A₇ = 630(0.812)⁷

A₇ = 630(0.23275134787)

A₇ = 146.633

A₇ = 146.6 grams.

Answer: 112.5

Step-by-step explanation: When line AB and CD intersect at point E, angle AEC equals BED so you set them equal to each other and find what x is. 5x -20 = x + 50, solving for x, which gives you 17.5. Finding x will tell you what AEC and BED by plugging it in which is 67.5. Angle BED and BEC are supplementary angles which adds up to 180 degrees. So to find angle CEB, subtract 67.5 from 180 and you get 112.5 degrees.

The diver will be 3 feet high 1 second after he leaves the board and the diver will hit the water after 1.12 seconds

The function is given as:

h(t) = -16t^2 + v*t + m

The variable v represents the velocity, while the variable t represents time

So, we have:

v * t = velocity * time

v * t = distance

Hence, v*t in the case of the diver represents distance

We have:

-16t^2

Where

a = -16 --- the acceleration

The variable t represents time

So, we have:

-16t^2 = -16 * time squares

-16t^2 = distance

Hence, -16t^2 in the case of the diver represents distance

To do this, we calculate h(1).

So, we have:

h(t) = -16t^2 + v*t + m

This gives

h(t) = -16t^2 + 9*t + 10

This gives

h(1) = -16 * 1^2 + 9*1 + 10

Evaluate

h(1) = 3

Hence, the diver will be 3 feet high 1 second after he leaves the board

Here, we set h to 0

-16t^2 + 9*t + 10 = 0

The polynomial for the perimeter of the rectangle can be expressed as P(n) = 2(2n+8) + 2(n-7), which simplifies to P(n) = 4n + 16 + 2n - 14.

Combining like terms, we get P(n) = 6n + 2. Therefore, the polynomial in standard form for the perimeter of the rectangle is P(n) = 6n + 2.

To find the perimeter of the rectangle, we need to add up the lengths of all four sides. The length of the rectangle is represented by 2n+8, so we have 2 sides of length (2n+8). The width of the rectangle is represented by n-7, so we have 2 sides of length (n-7). To calculate the perimeter, we add up the lengths of all four sides: (2n+8) + (2n+8) + (n-7) + (n-7). Simplifying this expression, we get 6n + 2, which is the polynomial in standard form for the perimeter of the rectangle.

The shortest distance between airports A and B that can be covered by an airplane flying from airport A at a heading of 300 (N 60 W) is =  401 miles.

The law of cosines, commonly referred to as the cosine rule or the cosine formula, is a trigonometric formula that simply establishes a relationship between the length of a triangle and the cosine of one of its angles. The length of the third side of a triangle can be calculated if we know the lengths of the first two sides and the angle between them.

An aircraft takes off from airport A with a heading of 300 (N 60 W). The aircraft changes its direction to 350 (N 10 W) after flying 320 miles, and after flying an additional 112 miles, it reaches airport B.

Below is an attachment with the problem's image. The two sides in this image are 112 miles and 320 miles apart, and the angle between them is 130 degrees. As a result, x has the value

So, by putting the values we get:

\(x=\sqrt{112^{2}+130^{2}-2(112)(130) \cos 130^{\circ}}\)

x = 401 miles.

Step-by-step explanation:

Given

a + b = 8 ( square both sides )

(a + b)² = 8² = 64

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

(a + b)² = 64 ← expand left side

a² + b² + 2ab = 64 ← substitute ab = 15

a² + b² + 2(15) = 64

a² + b² + 30 = 64 ( subtract 30 from both sides )

Degrees = Radians x 180/π

or

Degrees = 57.2958  x radians

Step-by-step explanation:

1 radian = 180/π degrees

1 radian = 57.2958 degrees

Multiply radians by this factor of 57.2958  to get the equivalent measure in degrees

π radians = 180°

2π radians = 360° which is the number of degrees in a circle

For anything greater than 2π radians you will have to subtract 360°

For example, 7 radians using the formula is 7 x (57.2958  ) ≈ 401.07°

But this still falls in the first quadrant, so relative to the x-axis it is
401.07 - 360 = 41.07°

Answer:

19 dimes and 13 quarters

Step-by-step explanation:

Let's start by defining some variables:Let's call the number of dimes the man has "d".

Let's call the number of quarters the man has "q".We know that the man has 32 coins in total, so we can write:

d + q = 32We also know that the total value of the change is 515 cents. Since dimes are worth 10 cents and quarters are worth 25 cents, we can write an equation for the total value in cents:

10d + 25q = 515

We now have two equations with two variables, which we can solve simultaneously. Let's rearrange the first equation to solve for one of the variables:

d = 32 - q

We can substitute this expression for "d" into the second equation:

10(32 - q) + 25q = 515Simplifying and solving for "q", we get:

320 - 10q + 25q = 515

15q = 195

q = 13

So the man has 13 quarters. We can substitute this value into the first equation to find the number of dimes:

d + 13 = 32

d = 19

Therefore, the man has 19 dimes and 13 quarters.

There are 19 dimes and 13 quarters.

Let x represent the number of dimes and y represent the number of quarters.

There are a total of 32 coins, so:

x + y = 32

We know that the total value of the change is 515 cents

. The value of x dimes is 10x cents and the value of y quarters is 25y cents. So:

10x + 25y = 515

We can simplify the first equation by solving for one variable in terms of the other:

x + y = 32x = 32 - y

Now we can substitute this expression for x into the second equation:

10(32 - y) + 25y = 515

Simplify and solve for y:

320 - 10y + 25y = 515

15y = 195y

y = 13

So there are 13 quarters. We can find the number of dimes by substituting y = 13 into x + y = 32:x + 13 = 32x = 19So there are 19 dimes.

So, There are 19 dimes and 13 quarters.

The approximate probability that the average price for 16 gas stations is over $4.69 is equals to the almost zero. Therefore, correct answer is option (a).

Under statistics, a z-score or standard score is used to identify how far from the population mean a given data point or raw score is. The following variation of the z-score formula,

z= ( x −μ)/σ/√n

Where, x--> observation score

μ-->mean

σ--> standard deviation

n--> number of sample

We have cost of unleaded gasoline in the area once will follow an unknown distribution,

Mean, μ= $4.59

Standard deviations, σ = $0.10

Sample size, n = 16

Observed value, x = $4.69

We have to calculate approximate probability for average price for 16 gas stations is over $4.69, i.e., P(x >4.69). Using the z-score formula,

P( (x −μ)/σ/√n > ( 4.69 - 4.59)/0.10/√16)

=> P(z > (4.69- 4.59)/0.10/√16)

=> P(z > 0.10/0.10/√16)

=> P(z >4) = 1 - P( z< 4)

Using the z-table, the approximate value of P(z < 4 ) is 0.999. Also, P( x> 4.69 )

= P( z>4) = 1 - 0.999 ~ 0.

Hence, required probability is almost zero.
