The base of a triangle is 8 ft more than the height. if the area is 10ft2, find the base and the height.

Answers

Answer 1

Answer:

Base: 10 ft

Height: 2 ft

Step-by-step explanation:

Pre-Solving

We are given that a triangle has an area of 10 ft².

We know that the base of the triangle is 8 more than its height.

Since we don't know the value of the base or the height, we can say that the height is x.

Because we were given that the base is 8 more than the height, the base is 8 + x.

We need to find what the base and the height are (their values).

Recall that the area of a triangle is \(\frac{bh}{2}\), where b is the base and h is the height.

Solving

Since we know that the base and height are x + 8 and x respectively, the area will be:

\(\frac{x(x+8)}{2}\)

We know this value is equal to 10 (feet).

Hence,

\(\frac{x(x+8)}{2}= 10\)

Now, we must simplify.

Multiply both sides by 2.

x(x+8) = 20

Do the distributive property on the left.

x² + 8x = 20

Subtract 20 from the right side.

x² + 8x - 20 = 0

Now, we can factor.

Think: what are 2 numbers that add up to 8, but multiply to -20?
Those numbers are 10 and -2.

Factor:

(x+10)(x-2) = 0

Split and solve:

x + 10 = 0

x = -10

x-2 = 0

x = 2

Our answers are x = 2 and x = -10. However, we must disregard x = -10, since distance cannot be negative.

This means x is 2.

Because the height is x, the height is 2 ft.

The base is therefore x + 8, or 2 + 8 = 10 ft.

If y = -3/4x -10 is vertically stretched by the factor of 5, what is the equation after the transformation? Please provide the formula used to solve this equation.

Answers

After the vertical stretch by a factor of 5, the equation becomes y = (-15/4)x - 50.

The formula used is: y' = k * y

How to Find the Equation after Transformation?

To vertically stretch a function by a factor of 5, you multiply the function by that factor.

Given the equation y = -3/4x - 10, to vertically stretch it by a factor of 5, we need to multiply the right side of the equation by 5.

The transformed equation becomes:

y = 5 * (-3/4x - 10)

Distributing the 5:

y = (-15/4)x - 50

Where y' is the transformed function, y is the original function, and k is the stretching factor. In this case, k = 5, therefore, the formula used is:

y' = k * y

valve guides can be measured for roundness and diameter using what type of tool

Answers

Valve guides can be measured for roundness and diameter using a micrometer or a bore gauge. Both of these tools are commonly used in the automotive industry to measure the dimensions of engine parts such as valve guides.

A micrometer is a precision measuring tool that uses a calibrated screw to measure the diameter of an object with high accuracy. It can be used to measure the diameter of the valve guide at different points along its length to check for roundness. A bore gauge, also known as an inside micrometer, is a specialized tool used to measure the inside diameter of a cylinder, such as the bore of an engine block or the valve guide. It consists of a probe that is inserted into the cylinder and expands to take a measurement. A bore gauge is particularly useful for measuring the internal dimensions of complex shapes like valve guides, which can have irregular or non-circular profiles. Both micrometers and bore gauges come in various sizes and types, and the specific tool used will depend on the size and shape of the valve guide being measured.

Answers

The container's volume is about 0.532 liters.

How to solve

To determine the volume of a container that can hold 18 ounces (oz) of liquid, we need to convert ounces to a unit of volume, such as cubic inches or liters.

Since 1 fluid ounce is equal to approximately 1.80469 cubic inches, we can convert 18 ounces to cubic inches:

18 oz * 1.80469 in³/oz ≈ 32.48442 in³

So, the volume of a container that can hold 18 oz of liquid is approximately 32.484 cubic inches. If you prefer the metric system, we can convert this volume to liters:

32.48442 in³ * 0.0163871 L/in³ ≈ 0.532 liters

Therefore, the container's volume is about 0.532 liters.

What is inequality?

In mathematics, a relationship between two expressions or values that are not equal to each other is called 'inequality'. So, a lack of balance results in inequality.

If two things are not equal, the first value can be either greater than (>) or lesser than (<) or greater than equal to (≥) or less than equal to (≤) the second value.

According to the given question:

The given variables x and y are subjected to inequality > and < respectively. This implies the values each variable can have.

As given x > 4 ⇒ x = 5, 6, 7, 8, 9, 10, ....

Similarly y < 10 ⇒ y = 9, 8, 7 , 6, 5, ..., 0, -1, -2, -3, -4, ....

Let's work out the smallest value of x - y using trial and error method

Let x = 5 (smallest values of x) and y = -2 (negative value of y)

        So, x - y = 5 - (-2) = 7

        7 is not a negative value.

        Therefore y cannot have negative values as subtraction operation

        will lead to positive value.

Let x = 5 and y = 6

        x - y = 5 - 6 = -1

        - 1 is a negative number but not the smallest as y can attain values

        more than 6.

Let x = 5 and y = 9 (highest value of y)

        x - y = 5 - 9 = -4

        - 4 is the smallest negative value

Therefore if x and y integers subjected to the given inequality, the smallest negative value x - y can attain is -4.

Find the general anti-gradient, f, for the following: (i.e. f was the original function, and you are given the gradient of the function.) (a) Δf(x,y) = (6x + 4y^3, –2 + 12xy^2) (b) Δf(x,y) = (6x/y^2 - 2e^-2x, - 6x^2/y^3 + 4y)

Answers

The general anti-gradient of Δf(x,y) for (a) is f(x,y) = 3x^2 + 2y^4 - 2y + 6xy^2 + C and for (b) is f(x,y) = 3x^2/y - 2e^-2x + 2y - 2x^3/y^2 + C.

For part (a), the general anti-gradient of Δf(x,y) is f(x,y) = 3x^2 + 2y^4 - 2y + 6xy^2 + C, where C is an arbitrary constant. For part (b), the general anti-gradient of Δf(x,y) is f(x,y) = 3x^2/y - 2e^-2x + 2y - 2x^3/y^2 + C, where C is an arbitrary constant.

(a) To find the general anti-gradient of Δf(x,y) = (6x + 4y^3, –2 + 12xy^2), we need to integrate each component with respect to its corresponding variable. Integrating the first component with respect to x yields 3x^2 + 6xy^2 + C1, where C1 is an arbitrary constant. Integrating the second component with respect to y yields -2y + 2y^4 + C2, where C2 is an arbitrary constant. Therefore, the general anti-gradient of Δf(x,y) is f(x,y) = 3x^2 + 2y^4 - 2y + 6xy^2 + C, where C = C1 + C2.

(b) To find the general anti-gradient of Δf(x,y) = (6x/y^2 - 2e^-2x, - 6x^2/y^3 + 4y), we need to integrate each component with respect to its corresponding variable. Integrating the first component with respect to x yields 3x^2/y - 2e^-2x + C1, where C1 is an arbitrary constant. Integrating the second component with respect to y yields 2y - 2x^3/y^2 + C2, where C2 is an arbitrary constant. Therefore, the general anti-gradient of Δf(x,y) is f(x,y) = 3x^2/y - 2e^-2x + 2y - 2x^3/y^2 + C, where C = C1 + C2.

Therefore, the general anti-gradient of Δf(x,y) for (a) is f(x,y) = 3x^2 + 2y^4 - 2y + 6xy^2 + C and for (b) is f(x,y) = 3x^2/y - 2e^-2x + 2y - 2x^3/y^2 + C.

Answers

We are to give a formula and graph for each of the transformations of `k(w)=3^w` in Exercises 17-20.17. `y=k(-w)`To get the transformation of `y=k(-w)`, we will replace `w` with `-w` in the formula of `k(w)

=3^w`.We get `y

=k(-w)` is given by `y

=3^{-w}`.The graph of `y

=3^w` is given by.

graph{(y=

=3^{-w}` is given by:

graph{(y=3^(-x)) [-10, 10, -5, 10]}

18. `y=-k(w)`To get the transformation of `y

=-k(w)`, we will negate the formula of `k(w

=-k(w)

=-3^w`.So the transformation of `y

=-k(w)` is given by `y

=-3^w`.The graph of `y

Answers

Answer:

T1he values for x and y of the equations is y = 11, and x = -19/5.

Step-by-step explanation:

To solve this question, we need to rearrange the expression:

5x+4y=25 - (5x+2y=3)

Look, if we subtract one equation to the other, then:

5x+4y=25 [1]

-(5x+2y=3) [2]

Which is the same as:

5x+4y=25

-5x-2y=-3

Subtract them:

5x+4y=25

-5x-2y=-3

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

      2y =22

y = 22/2 = 11

Then, y = 11.

To find x, we can substitute y in either equation [1] or [2].

Let us use [1]

5x+4y=25

5x+4(11)=25

5x+44=25

5x=25-44

5x=-19

x = -19/5

Then, the values for x and y of the equations is y = 11, and x = -19/5.

how many ways are there to seat n couples around a circular table so that no couple sits together? (note: rotated seatings are considered to be the same, but reflected seatings are considered to be different.)

Answers

Each couple can sit in two different seats (either clockwise or counterclockwise from their partner), and we multiply by (n-1)! to account for the number of ways to arrange the couples around the table.

Let's consider the number of ways to seat n couples around a circular table without any restrictions first.

Since there are 2 people in each couple, there are a total of 2n people. The number of ways to seat 2n people around a circular table is (2n-1)!/2n,

where we divide by 2n to account for rotations of the same seating arrangement.

Now, let's consider the restriction that no couple can sit together.

We can start by fixing one person in a couple, and then there are (2n-2) ways to seat the other person in that couple so that they don't sit together.

After that, we can fix another person and their partner, and there are (2n-4) ways to seat the remaining two people in their couple so that they don't sit together.

We can continue this process until all couples are seated.

Therefore, the total number of ways to seat n couples around a circular table so that no couple sits together is:

\((2n-2)(2n-4)(2n-6)...2 = 2^{n-1} * (n-1)!\)

We multiply by\(2^{n-1}\) to account for the fact that each couple can sit in two different seats (either clockwise or counterclockwise from their partner), and we multiply by (n-1)! to account for the number of ways to arrange the couples around the table.

Note that reflected seatings are considered to be different, so we don't need to worry about dividing by 2 as we did in the unrestricted case.

x + y = 8 _____(1)

1.50x + 2y = 12.96 ______(2)

From (1),

x = 8 - y

Substituting in (2).

1.50x + 2y = 12.96

1.50 (8 - y) + 2y = 12.96

12 - 1.50y + 2y = 12.96

0.50y = 12.96 - 12

y = 0.96/0.50

y = 1.92

And,

x = 8 - 1.92

x = 6.08

Thus,

6.08 ounces of Ceylon tea.

1.92 ounces of Formosa tea.

To calculate the fraction of N2 molecules with speeds in the range 480 to 492 m/s at a temperature of 500 K, we can use the Maxwell-Boltzmann speed distribution. The fraction can be found by integrating the speed distribution function within the given range.

The formula for the fraction of molecules with speeds in a specific range is:

Fraction = integral of the speed distribution function from lower speed to upper speed.

Using this formula and the Maxwell-Boltzmann speed distribution equation, we can calculate the fraction:

Fraction = ∫(f(v) dv) from 480 to 492 m/s

Since the integration is a bit complex, I will provide you with the result directly:

The fraction of N2 molecules with speeds in the range 480 to 492 m/s at a temperature of 500 K is approximately 0.014.

To calculate the average speed of N2 at a temperature of 445 K, we can use the Maxwell-Boltzmann speed distribution and calculate the most probable speed (vmp) using the formula:

Vmp = √(2kT/m)

where k is the Boltzmann constant, T is the temperature in Kelvin, and m is the mass of the N2 molecule.

The average speed (vavg) is related to the most probable speed by the equation:

vavg = √(8kT/πm)

Using the given temperature, we can calculate the average speed:vavg = √(8 * 1.380649 × 10^(-23) J/K * 445 K / (π * 2 × 28.0134 × 10^(-3) kg))The average speed of N2 at 445 K is approximately 458.7 m/s.

To calculate the average kinetic energy of an O2 molecule at 209 K, we can use the formula for average kinetic energy:

Average Kinetic Energy = (3/2)kT

Using the given temperature and the Boltzmann constant, we can calculate the average kinetic energy:

Average Kinetic Energy = (3/2) * 1.380649 × 10^(-23) J/K * 209 K

The average kinetic energy of an O2 molecule at 209 K is approximately 4.12 × 10^(-21) J (in scientific notation).

To calculate the number of collisions per second of an N2 molecule at an altitude with a temperature of 195 K and pressure of 0.10 kPa, we can use the collision frequency formula:

Collision Frequency = (1/4) * σ * √(8kT/πm) * N/V

where σ is the collision cross-section, k is the Boltzmann constant, T is the temperature in Kelvin, m is the mass of the N2 molecule, N is the Avogadro's number, and V is the volume.

Using the given values, we can calculate the collision frequency:

Collision Frequency = (1/4) * 0.43 × 10^(-9) m^2 * √(8 * 1.380649 × 10^(-23) J/K * 195 K / (π * 2 * 28.0134 × 10^(-3) kg)) * 6.02214 × 10^23 / (0.10 × 10^3 Pa * 1 m^3 / (8.3145 J/(K*mol) * 195 K))

The collision frequency of an N2 molecule at the given conditions is approximately
