Answer:

  15.0 in

Step-by-step explanation:

You want the height of a cone with radius 8 in and slant height 17 in.

The right triangle shown in the figure has height h, base x = 8 in, and slant height y = 17 in. The Pythagorean theorem tells you the relationship between these side lengths:

  x² +h² = y²

  8² +h² = 17²

  h² = 17² -8² = 289 -64 = 225

  h = √225 = 15.0

The height of the cone is 15.0 inches.

Additional comment

A triple of 3 integers that form the sides of a right triangle is called a "Pythagorean triple." The triple in this problem is one of those: {8, 15, 17}. Other Pythagorean triples you will often see in algebra, trig, and geometry problems are {3, 4, 5}, {5, 12, 13}, {7, 24, 25}, {9, 40, 41}. You will also see multiples of these, for example 3×{3, 4, 5} = {9, 12, 15}.

It can be worthwhile to remember some of these. For this problem, recognizing 8 and 17 as part of the triple {8, 15, 17} means you can write down the answer with no further work.

Answer:

Therefore, the answer is: The graph of the equation is a straight line passing through the points (0, -2), (7, 2), and (-7, -6).

Step-by-step explanation:

The given equation is y = (4/7)x - 2.

To graph this equation, we need to plot points on a coordinate plane. We can do this by choosing values of x and then finding the corresponding values of y using the equation.

Let's choose some values of x and find the corresponding values of y:

When x = 0, y = (4/7)(0) - 2 = -2

When x = 7, y = (4/7)(7) - 2 = 2

When x = -7, y = (4/7)(-7) - 2 = -6

We now have three points: (0, -2), (7, 2), and (-7, -6). We can plot these points on a coordinate plane and draw a line through them to get the graph of the equation.

Answer: 48.76 square inches.

Step-by-step explanation: A regular pentagonal prism has 7 faces: 2 pentagonal bases and 5 rectangular faces.

To find the surface area, we need to find the area of each face and add them up.

The area of one pentagonal base can be found using the formula:

A = (5/4) * (edge length)^2 * cot(π/5)

Substituting the given values, we get:

A = (5/4) * (2)^2 * cot(π/5)

≈ 6.8819 square inches (rounded to the nearest hundredth)

Since there are two pentagonal bases, their total area is:

2A ≈ 13.7638 square inches

The area of one rectangular face can be found using the formula:

A = (edge length) * (height)

Substituting the given values, we get:

A = 2 * 3.5

= 7 square inches

Since there are five rectangular faces, their total area is:

5A = 5 * 7 = 35 square inches

Therefore, the total surface area of the regular pentagonal prism is approximately:

13.7638 + 35 = 48.7638 square inches

Rounding to the nearest hundredth, we get:

Surface area ≈ 48.76 square inches.

The surface area of a regular pentagonal prism is 193.82 square inches.

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

The formula for the surface area of a regular pentagonal prism is:

SA = 5 × base area + 5 × lateral face area

where the base area is the area of one of the pentagonal bases, and the lateral face area is the area of one of the rectangular faces.

Since the base is a regular pentagon, we can use the formula for the area of a regular pentagon:

Area of pentagon = (1/4) × n × s² × tan(180°/n)

where n is the number of sides of the pentagon (which is 5 since it's a regular pentagon), and s is the length of one of its sides.

In this case,

s = 2 inches

Area of pentagon = (1/4) × 5 × 2² × tan(180°/5)

Area of the pentagon = 6.8819 square inches

This is the area of one of the pentagonal bases.

Since there are two bases,

The total base area is:

Base area = 2 × 6.8819

                 = 13.7638 square inches

Now,

Each lateral face is a rectangle with a width equal to the base edge length (2 inches) and a height equal to the height of the prism (3.5 inches).

Lateral face area.

= base edge length × height

= 2 inches × 3.5 inches

= 7 square inches

Since there are five lateral faces, the total lateral face area is:

Lateral face area

= 5 × 7

= 35 square inches

Now we can add up the base area and lateral face area to get the total surface area:

SA = 5 × base area + 5 × lateral face area

     = 5(13.7638) + 5(35)

     = 193.819 square inches

Rounding this to the nearest hundredth.

SA = 193.82 square inches

Thus,

The surface area of a regular pentagonal prism is 193.82 square inches.

Answer:

∠PQT and ∠TQR.

Step-by-step explanation:

If you're still confused about which angles are supplementary, let me give you a hint. Imagine that RP←→ is a giant ruler that you can use to measure the angles. Now, if you place the ruler on ∠PQT and ∠PQS, you'll see that they are too small to fit the whole ruler. They only cover half of it, which means they add up to 90 degrees. That's not what we want, we want 180 degrees!

Similarly, if you place the ruler on ∠TQS and ∠SQR, you'll see that they are too big to fit the whole ruler. They overlap each other, which means they are equal. And if they are equal, they must be 90 degrees each, because that's the only way two angles can add up to 180 degrees. But we don't want two 90 degree angles, we want two different angles!

The only option left is ∠PQT and ∠TQR. If you place the ruler on them, you'll see that they fit perfectly on the whole ruler. They cover it from end to end, which means they add up to 180 degrees. That's exactly what we want! So the correct answer is ∠PQT and ∠TQR. Congratulations, you've just solved a tricky geometry problem with a simple tool!

The possible rational zeros of the polynomial function are

±1, ±3, ±9, ±1/2, ±3/2, ±9/2

We have,

To find the possible rational zeros of the polynomial function P(x), we can use the Rational Root Theorem.

According to the theorem,

Any rational zero of a polynomial function with integer coefficients must have the form p/q, where p is a factor of the constant term and q is a factor of the leading coefficient.

In this case,

The constant term is -9, which has factors of ±1, ±3, ±9.

The leading coefficient is 2, which has factors of ±1, ±2.

So the possible rational zeros are:

±1/1, ±3/1, ±9/1, ±1/2, ±3/2, ±9/2

Simplifying the fractions, the possible rational zeros are:

±1, ±3, ±9, ±1/2, ±3/2, ±9/2

The measure of angle a is 30° , angle b is 60° and angle c is 105°  calculated from the properties of angles and of triangle.

When two straight lines intersect each other at some angle, say line AB intersect line CD, then the opposite angles formed by the two lines are called vertically opposite angles. A pair of vertically opposite angles are equal to each other.

Angle a is formed at the intersection of the two straight lines, say AB and CD. The angle opposite to angle is 30°.

Thus from the definition of vertically opposite angles we get,

Angle a = 30° , since pair of vertically opposite angles are equal to each other.

In a right angle triangle one of three angles is 90° and the other two angles are acute angles. The sum of all the angles of a triangle is 180°.

Say  ΔMNO is a right angle triangle where angle a is one of the other two acute angles (where angle a = 30°).

The third angle (acute) is b.

Thus from the sum of triangle we get,

Angle a + Angle b + 90° = 180°

⇒ 30° + Angle b + 90° = 180°

⇒ Angle b = 60°

Here angle c is an angle labelled in a triangle (on the left of the previous triangle, say ΔMNO).

Two angles are said to be adjacent angles when they have a common vertex and side. The pair of adjacent angles sum to 180° , that is they are supplementary angles.

The adjacent angle of Angle c is 75°.

Thus, Angle c + 75° = 180°

⇒ Angle c = 105°

Lateral surface area = 2H(L + W)

Total surface area = 2 LW + 2 WH + 2 HL

We need to know the prism's dimensions in order to determine its lateral and total surface area for a rectangular base prism. The rectangular prism's length, width, and height are assumed to be L, W, and H, respectively.

The sum of the areas of the rectangular prism's four lateral faces determines its lateral surface area. Since every sidelong face is a square shape with a level of H and a width of one or the other L or W, the parallel surface region is given by:

Lateral Surface Area = 2H(L + W)

The sum of the areas on each of the six faces creates the rectangular prism's total surface area. This incorporates the four sidelong faces, as well as the top and base faces, which are additionally square shapes with aspects L x W. Consequently, the all out surface region is given by:

Total Surface Area = 2(LW + LH + WH)

So, if you know the dimensions of the rectangular prism, you can use these formulas to find its lateral and total surface area.

Since the number of men must be a whole number, we can round it up to 267. Therefore, there were initially 267 men in the fort before the reinforcement arrived.

Let's solve this problem step-by-step:

1. Initially, the fort is provisioned for 42 days.
2. After 10 days, a reinforcement of 200 men arrives.
3. With the additional men, the remaining food will now last for 24 days.

Let x represent the initial number of men in the fort.

Since the fort was provisioned for 42 days initially, we can write an equation for the total amount of food:

Total food = x men * 42 days

After 10 days, 200 men arrive and the remaining food lasts for 24 days:

Remaining food = (x + 200) men * 24 days

Since the total food and remaining food are equal, we can set the two equations equal to each other:

x * 42 days = (x + 200) * 24 days

Now, let's solve for x:

42x = 24x + 4800

Subtract 24x from both sides:

18x = 4800

Step-by-step explanation:

We can use the formula for exponential growth to find the rate at which the sunfish gains mass:

M(t) = M(0) * e^(kt)

where:

M(0) = the initial mass of the sunfish (which we don't know)

k = the growth rate constant (which we also don't know yet)

t = the elapsed time since the sunfish was born (in days)

e = the mathematical constant approximately equal to 2.71828...

We are given the formula for M(t), which is:

M(t) = 4 * (81/49)^t

This means that M(0) = 4 * (81/49)^0 = 4.

To find the growth rate constant k, we can use the fact that the sunfish gains 2/7 of its mass every day. This means that the daily growth rate is 2/7 of the current mass. In other words, the daily growth rate is:

(2/7) * M(t)

We can relate this to the exponential growth formula by taking the derivative of M(t) with respect to t:

dM/dt = k * M(t)

Taking the derivative of M(t), we get:

dM/dt = ln(81/49) * 4 * (81/49)^t

Setting this equal to the daily growth rate, we get:

(2/7) * M(t) = ln(81/49) * 4 * (81/49)^t

Simplifying this expression, we get:

k = ln(81/49) * 4/7

Using a calculator, we can evaluate this expression to get:

k ≈ 0.0919

Therefore, the rate at which the sunfish gains mass is given by:

dM/dt = 0.0919 * M(t)

To find out how much mass the sunfish gains in one day, we can substitute M(t) = 4 * (81/49)^t into this formula and evaluate it at t = 1 (since we want to know the daily rate of change):

dM/dt = 0.0919 * 4 * (81/49)^1

dM/dt ≈ 0.54

This means that the sunfish gains 0.54 milligrams every day. To express this as a fraction of its mass, we can divide by the current mass:

(0.54/4) ≈ 0.1375

So the sunfish gains approximately 2/7 (or 0.2857) of its mass every 2.08 (or 7/2.54) days. Rounded to two decimal places, this is 0.14 or approximately 2/7 of its mass every 2.08 days.

One way for Paul to display his data is by using a scatter plot. A scatter plot is a graph that uses ordered pairs to represent data points. In this case, each data point would represent a friend's score and the number of minutes they spent studying science over the weekend.

To create a scatter plot, Paul would plot each data point as an ordered pair on a coordinate plane. The x-coordinate would represent the number of minutes spent studying, and the y-coordinate would represent the friend's score on the science test. Paul could then use a title and labels for the x and y axes to make the graph clear and informative.

A scatter plot is a good choice for this data because it allows Paul to easily see any relationship between the amount of time spent studying and the scores on the science test. He can also use the graph to identify any outliers or patterns in the data.
