The work is done in compressing the spring from a length of 15 inches to a length of 13 inches are the 0.897ftlb.

Work Done:According to the paintings-power theorem, the internet paintings performed on an item equals the alternate withinside the power of the item . If the simplest alternate withinside the power located is withinside the capability power (say U) of the item, then the internet paintings performed W=△U.

Answer and Explanation:When a spring is compressed x in with the aid of using a pressure F,

F=kx, where k is the spring constant.

Since it's miles for the reason that the spring is compressed to 8in from 21in, that is, a compression of (21−eight)=13in, we obtain

F=kx⇒k=Fx=10lb1312ft=12013lbft−1.

Using the theorem, the internet paintings performed on an item equals the alternate withinside the power of the item. In this situation the simplest alternate in power is withinside the capability power of the spring while it's miles compressed with the aid of using x gadgets of duration, which is 12kx2. (k is the spring constant.)

The capability power of the spring while it's miles compressed to 15cm=0.5k(21−1512)2

The capability power of the spring while it's miles compressed to 13cm=0.5k(21−1312)2

Work Done equals the alternate withinside the capability power while it's miles compressed from 15in to 13in

=0.5k[(21−1312)2−(21−1512)2]=0.512013[(21−1312)2−(21−1512)2]≈ 0.897ftlb

To rewrite the expression tan 0 x csc 0 in terms of sine and cosine, we can use the following trigonometric identities:

The reciprocal identity: csc 0 = 1/sin 0

The tangent identity: tan 0 = sin 0/cos 0

The Pythagorean identity: sin^2 0 + cos^2 0 = 1

Substituting these identities into the given expression, we get:

tan 0. csc 0 = (sin 0/cos 0) * (1/sin 0)

Using the reciprocal identity and the Pythagorean identity, we can simplify this expression further to get:

tan 0. csc 0 = (sin 0 * 1)/(cos 0 * sin 0)

Next, we can cancel out the sin 0 term on the numerator and denominator to get:

tan 0. csc 0 = 1/cos 0

Finally, we can use the Pythagorean identity again to rewrite the denominator as:

tan 0. csc 0 = 1/sqrt(1 - sin^2 0)

Therefore, the final simplified expression is:

tan 0. csc 0 = 1/sqrt(1 - sin^2 0)

This is the final answer.

Step-by-step explanation:

The change rate at the top of the mt is given as - 2.5 ° / hr

 at the base it is 1/5th of this number

1/5 * -2.5   =  - 0.5 °C  per hour

Answer:

x = 4°

Step-by-step explanation:

The box in the top right angle of the diagram lets us know that all of these angles equal 90°  !

To find x, we just need to do simple algebra and use the info above.

21x + 6 = 90 °

21x = 90 - 6

21x = 84

The value of c that satisfies the Mean Value Theorem for this problem are given as follows:

A. [tex]4\sqrt{3}[/tex]

The function for this problem is given as follows:

f(x) = x + 48/x.

The bounds of the interval are given as follows:

a = 3, b = 16.

The derivative of the function is given as follows:

f'(x) = 1 - 48/x².

The numeric value of the derivative at x = c is given as follows:

f'(c) = 1 - 48/c²

The numeric values of the functions at the bounds are given as follows:

Then the value of c is obtained as follows:

1 - 48/c² = 0/16

1 - 48/c² = 0

48/c² = 1

c² = 48

c = square root of 48.

[tex]c = \sqrt{16 \times 3}[/tex]

c = [tex]4\sqrt{3}[/tex]

Option A, as we have to be reminded that the interval is [3,16], hence the negative root is not considered.

No, I do not agree with Buffett as the wealthy barely have any struggles, and them only paying less than a dollar in taxes will make the government add to the less fortunate. Meaning: If a large number of people aren't paying taxes, the government would not be getting a certain amount of money p/m&yr (per month and year), and that's a huge problem because hundreds of thousands of dollars are being spent every day.  And where does the government get that income?

Equation that represents the height of parasail (y) based on the speed of the motorboat (x) is given by y sinβ = Xt

What is parasail?

A kind of sports game where a person climbs in a parachute and the parachute is tied to a moving motorboat.

Generally, parasail is tied with a motorboat by a special chord. The position of chord of parasail is not properly perpendicular to the direction of boat moving on. There is an angle between the chord and horizontal surface of motorboat.

Let the angle is denoted by β

The vertical height of parasail over the boat=h

the length of chord that means distance from boat to the parasail = y

speed of boat = X

As per trigonometric formula, opposite/ hypotenuse = sinβ

                                        sinβ = h/y

   hence, height of parasail over the boat surface, h= y sin β

                             Now, from the height, speed and time equation

                          height = speed × time

 at time t, the height of parasail ysinβ  which attached to a boat of speed X can be represent by the equation.

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).

What is the formula's percentage?

By dividing the value by the entire value and multiplying the result by 100, one may determine the percentage. The percentage calculation formula is (value/total value)100%.

Detailed explanation:

Data

Total cost: $11.325

8% state tax

$53 for license plates

$40 for an emissions inspection.

Process

1.- Determine the 8% of the car's cost.

11325 ———————— 100%

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given,  On a box of chicken patties state that one patty should be cooked for 2.5 minutes in the microwave.

If more than one patty is cooked, an additional 1.5 minutes should be added per patty.

So,  The equation in slope-intercept form to model the cooking time in

minutes, y, for x patties.

If we write this as y = 1.5x + 2.5 and put x = 0 , y = 2.5 which is not satisfying the given statement.

The distributive property states that for any numbers a, b, and c, a * (b + c) = a * b + a * c. To evaluate 7 times 8 and four-fifths, we can use the distributive property to separate the two factors. First, we calculate 7 times 8, which is equal to 56. Then, we calculate four-fifths, which is equal to 28/5. We then use the distributive property to multiply the two factors together, which is (7 * 8) * (4/5).
