Answer:

122.5 pounds.

Step-by-step explanation:

f = kaw^2

So, k = f/aw^2

From the given data:

k = 64.8/(500*18)

  = 0.0004

When a = 250 and w = 35:

f = 0.0004*250*35^2

 = 122.5

Answer:

A, 6, 8, 10

Step-by-step explanation:

since you know that it is a right triangle, you can use pythagorean theorem, which states that A^2+B^2=C^2. so you add the squares of the smaller numbers, then take the square root of that number to get the answer. it is guess and check, but its a good theorem to know.

6^2=36

8^2=64

36+64=100

√(100)=10

Answer:

[tex]A=-3[/tex]

[tex]C=6[/tex]

[tex]B=4[/tex]

[tex]D=9[/tex]

Step-by-step explanation:

From the question we are told that:

Center of hyperbola at ( 6 , 9 )

Focus of hyperbola at ( 11 , 9 )

Vertex of hyperbola at ( 9 , 9)

Equation of hyperbola [tex]\frac{(x-C)^2}{A^2} -\frac{(y-D)^2}{B^2}=1[/tex]

Generally the C and D of the hyperbola equation is mathematically given by

[tex]Centers (6,9)[/tex]

[tex]C=6[/tex]

[tex]D=9[/tex]

Generally the A and B a of the hyperbola equation is mathematically given by

 [tex]A=x_c-x_v[/tex]

 [tex]A=6-9[/tex]

 [tex]A=-3[/tex]

 [tex]C'=x_c-x_f[/tex]

 [tex]C'=6-11[/tex]

 [tex]C'=-5[/tex]

Therefore with Center,Focus ,Vertex on the same line

 [tex]B^2=C'^2-A^2[/tex]

 [tex]B^2=(-5^2)-(-3^2)^2[/tex]

 [tex]B^2=(25)-(9)[/tex]

 [tex]B^2=16[/tex]

Both (x + y = 15) and (0.5x + 0.65y = 9.00) make up the equation system.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

We have LHS = RHS (left hand side = right hand side) in every mathematical equation.

To determine the value of an unknown variable that represents an unknown quantity, equations can be solved.

The statement is not an equation if there is no "equal to" sign in it

According to our question-

x is the quantity of oranges.

y is the quantity of apples.

Oranges plus apples equal 15, or x plus y equals 15, so Aisha purchased 15 pieces of fruit.

Apples cost $0.65 and oranges cost $0.50. The fruit cost Aisha $9.00.

0.5x (the total cost of the oranges) + 0.65y (the total cost of the apples) equals 9.00 (the total cost of the fruit).

x + y = 15

0.5x + 0.65y = 9.00

As a result, the system of equations is (0.5x + 0.65y = 9.00) and (x + y = 15).

The sum of first 20 terms of the AP will be -206.25

As in AP, let us assume that the "a" be the first term and 'd' be the common difference.

So, the value of nth term can be determined by using formula: a_n=a+(n-1)d, where, n = number of terms, and d = common difference.

So, the value of 19th terms = a+(19-1)d = a+18d = -5 -----(i)

And the value of 15th term = a+(15-1)d = a+14d = -7(1/2) ----(ii)

Now subtracting (ii) from (i),

We will get,

4d = 2(1/2)

=>4d = 2.5

=>d = (2.5/4) = 0.625

Now putting value of "d" in (i)

We will get,

a+(18*0.625) = -5

a=-5-11.25 = -16.25

We have, the formula for finding the sum of terms:

Sum of terms can be determined by using formula:

Sum = (n/2) × [2a + (n-1)d]

Here, n = 20, a = -16.25, d = 0.625

We will get sum of first 20 terms as:

[tex](n/2)\times [2a + (n-1)d]\\(20/2) \times [2 \times -16.25+(20-1)0.625]\\[/tex]

Step-by-step explanation:

The residual values are -0.1, 3.8, 0.32, and 0 respectively for the given coordinate pairs.

A residual is a difference between the observed value (y) and the predicted value (y-hat) for a given x value. To find the residual for each coordinate pair (x,y), we need to substitute the x value into the equation for the line of best fit and calculate the difference between that value and the observed y value.

The equation for the line of best fit is y = 1.1x + 3.4

The residual for each coordinate pair (x,y) is given by -

Residual = Yactual - y

A. (5, 8.8) ; Yactual = 8.8

Residual = 8.8 - (1.1(5) + 3.4) = - 0.1

B. (2.5, 9.95) Yactual = 9.95

Residual = 9.95 - (1.1(2.5) + 3.4) = 3.8

C. (0, 3.72) Yactual = 3.72

Residual = 3.72 - (1.1(0) + 3.4) = 0.32

D. (1.5,5.05)​ Yactual =

Residual = 5.05 - (1.1(1.5) + 3.4) = 0

It's worth noting that residuals are used to measure how well the line of best fit represents the data set. The residuals should be as close to zero as possible, indicating that the line of best fit is a good representation of the data set.

A domain has [-1, 1]

Now, According to the question:

Let's know:

How do you find the domain?

Let y = f(x) be a function with an independent variable x and a dependent variable y. If a function f provides a way to successfully produce a single value y using for that purpose a value for x then that chosen x-value is said to belong to the domain of f.

A square root with a negative number under the root cannot produce a real number. This means that [tex]1-x^2[/tex] must be greater than or equal to zero.

Squaring a real number will always produce a positive number, so [tex]x^{2}[/tex]must be equal to or smaller than 1. This means x is between 0 and 1, giving the domain of [0,1].

A range of fundamental, unchanging values may exist in the world, according to ethical pluralism.

According to ethical pluralism, the world may contain a variety of essential and unchangeable values. There may be more, but happiness and respect for people are two possible ones.

The notion of ethical plurality holds that there are various beliefs about what is "good" and "wrong" (moral norms), some of which may be incompatible and/or out of line with your own personal moral standards. Working in foreign societies, where you could encounter varying norms, is a component of international involvement.

A graph which represents the solutions to this equation x² + 8x = -20 include the following: B. Linear-quadratic system graph shows upward parabola with vertex at (minus 4, 4) and passing through (minus 2, 8), and (minus 6, 8).

In Mathematics, the graph of every quadratic functions (equations) is either an upward or downward parabola, which is typically a u-shaped curve. This ultimately implies that, the graph of a quadratic function (equation) would always form a parabolic curve.

Next, we would re-write the given quadratic function in standard form by equating it to zero (0) as follows;

x² + 8x = -20

Adding 20 to both sides of the linear-quadratic equation, we have the following:

x² + 8x + 20 = -20 + 20

x² + 8x + 20 = 0

In this scenario, we would use an online graphing calculator to plot the graph of the given quadratic function and then determine the point of intersection and vertex.

y = x² + 8x + 20

By critically observing the graph of the given quadratic function, we can logically deduce that the solutions and vertex are as follows;

x = -6, y = 8.

x = -2, y = 8.

Vertex = (-4, 4).

Answer:

There might be an error in the question, the result below should be the correct answer. It is not possible for a^2+b^2+c^2 to be the answer.

(a+b+c)(a-b+c) = a^2 +2ac - b^2 + c^2

Step-by-step explanation:

(a+b+c)(a-b+c) = a^2 - ab +ac + ba - b^2 +bc + ca - cb + c^2 (expanding the two terms in brackets first)

Since ab = ba, ac = ca and bc = cb,

-ab and ba can be cancelled out

bc and -cb can be cancelled out

Hence, (a+b+c)(a-b+c) = a^2 +2ac - b^2 + c^2

This is what I have obtained through expansion, then simplification by cancelling out the common terms.

The XYZ coordinates are read as x-axis, y-axis and z-axis respectively.

Here we know that the x-axis is the horizontal line along which the wall to your left and the floor intersect where as the y-axis is the horizontal line along which the wall to your right and the floor intersect and the z-axis is the vertical line along which the walls intersect.

Here we also know that x-coordinate is measured along the east west axis, the y-coordinate is measured along the north south axis, and the z-coordinate measures height or elevation.

And it is used for a three-dimensional structure where the x-axis and y-axis represent the first two dimensions and the z-axis is the third dimension.

Step-by-step explanation:

The average speed of the plane from Winnipeg to Red Deer is 400 km/h

Average speed is total distance travelled over total time taken.

Since a plane flew from Red Deer to Winnipeg, a flying distance of 1260 km. On the return journey, due to a strong head wind, the plane travelled 1200 km in the same time it took to complete the outward journey. On the outward journey, the plane was able to maintain an average speed 20 km/hr greater than on the return journey.

Let

Since the plane travels 1260 km on the outward journey, we have that

1260 = vt  (1)

Also,  the plane travels 1200 km on the inward journey, we have that

1200 = v't  (2)

Since the plane was able to maintain an average speed 20 km/hr greater than on the return journey, we have that

v = v' + 20 (3)

Substituting equation (3) into (1), we have that

1260 = (v' + 20)t  (4)

The required equations are

1260 = v't + 20t  (4)

1200 = v't  (2)

Subtracting equations, (2) from (4), we have that

1260 = v't + 20t  (4)

-

1200 = v't  (2)

60 = 20t

t = 60/20

t = 3 h

From equation (2), we have that the average speed

v' = 1200/t

Substituting t = 3 into the equation, we have that

v' = 1200/3

v' = 400 km/h

So, the average speed is 400 km/h
