Answer:

W=2001.24 newton meters

Caution: check units and arithmetic - I often make errors.

Step-by-step explanation:

Work is force times distance.

Denote height by h where h=0 is at ground level.

Denote the mass of the bucket and rope at height h by m(h).

The rate at which the bucket loses mass with height is (20-16)/10=0.4 kg/m

The rate at which the rope between the bucket and the top of the building loses mass is 0.4 kg/m

The initial mass of the bucket and rope is

[tex]m_{0}=20+0.4+0.4(10)=24.4[/tex]

The mass at height h is

[tex]m(h)=24.4-0.8h[/tex]

The force required at height h is

m(h)g

where g is the gravitational acceleration.

g=9.81 meters/sec/sec

The work required is

[tex]\int\limits^b_a {m(h)g} \, dh[/tex]

Where a=0 and b=10

[tex]g\int\limits^b_a {(24.4-0.8h)} \, dh=g(24.4h-0.4h^2)\left \{ {{10} \atop {0}} \right.[/tex]

g(244-40)=204g

W=2001.24 newton meters

Answer:

x = 41.81°, 138.19°, 210°, 330°

Explanation:

3cos(2x) + sin(x) = 1

subtract one from both sides

→ 3cos(2x) + sin(x) − 1 = 0

rewrite using trigonometry identities

→ 2 + sin(x) − 6sin²(x) = 0

solve x by substitution

f(x) = 2 + sin(x) − 6sin²(x)

= 2 + 4sin(x) - 3sin(x) − 6sin²(x)

= −2sinx(3sinx −2) − (3sinx−2)

= (3sinx −2)(−2sinx−1)

= −(3sinx −2)(2sinx+1)

f(x) = 2 + sin(x) − 6sin²(x) = 0

= −(3sinx −2)(2sinx+1) = 0

(3sinx −2) = 0 (2sinx+1) = 0

→sinx = 2/3 →sinx = −1/2

x = 41.81°, 138.19° x = 210°, 330°

Answer:

Both are equal

4.5 = 9/2

4.5 = 4.5

Hope it will help :)

Answer:

They are equal

Step-by-step explanation:

When we simplify 9/2 and divide, we get the answer 4.5, which is equal to 4.5. Therefore, neither number is larger and they are equal, just written in different ways.

Answer:

[tex]\frac{49}{9}[/tex]

Step-by-step explanation:

Given

[tex](\frac{-3}{7})^{2!}[/tex]

Required

Determine the reciprocal

If a number is x, the reciprocal is: 1/x

So, the reciprocal of [tex](\frac{-3}{7})^{2!}[/tex] is:

[tex]\frac{1}{(\frac{-3}{7})^{2!}}[/tex]

[tex]2! = 2*1 =2[/tex]

So, we have:

[tex]\frac{1}{(\frac{-3}{7})^{2}}[/tex]

[tex]\frac{1}{(\frac{-3^{2}}{7^{2}})}[/tex]

Evaluate all exponents

[tex]\frac{1}{(\frac{9}{49})}[/tex]

Take inverse of 9/49

[tex]\frac{49}{9}[/tex]

Hence, the reciprocal of [tex](\frac{-3}{7})^{2!}[/tex] is [tex]\frac{49}{9}[/tex]

Answer:

55.9

Step-by-step explanation:

The ball takes 3 seconds to go up 55.9 meters.

3^2=9

-4.9 x 9 = -44.1

30 x 3 = 90

-44.1 + 90 = 45.9

45.9 + 10 = 55.9

Answer:

Think of it as a small number and a large number. If the large number is being divided by a small number, of course that would be larger than the small number being divided by the large number.

The statement /B < B/A is true if the 0 < A < B because the denominator is small so the value of B/A is larger.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have:

A/B < B/A

If you use the principle that the fraction must not be incorrect and have the value A/B1 (i.e., A and B are both positive), then this is true for positive values.

If  A/B = 2/3

Then B/A = 3/2

If A/B < B/A

2/3 < 3/2   (True)  if 0 < A < B

5/7 < 7/5  (true)  if 0 < A < B

Thus, the statement /B < B/A is true if the 0 < A < B because the denominator is small so the value of B/A is larger.

Answer:

E

Step-by-step explanation:

You have to get t^2 in the first equation.

x = t^3                         Take the cube root of both sides

[tex]\sqrt[3]{x} = \sqrt[3]{t^3}[/tex]

[tex]\sqrt[3]{x}=t[/tex]                         Now square both sides

[tex](\sqrt[3]{x})^2 = t^2[/tex]

[tex]x^\frac{2}{3} = t^2[/tex]

Now you can substitute into the second equation

y = t^2 - 2

y = [tex]x^\frac{2}{3}[/tex] - 2

Answer:

y=155, x=65

Step-by-step explanation:

y+25=180

y=155

y=90+x

155=90+x

x=65

if my answer helped please mark as brainliest.

The required measure of angles x and y are 65° and 155° respectively.

Following the given figure, to determine the value of y and x.

In the figure angles y and 25° are supplementary angles, while x, 90°, and 25° are the angles of a triangle.

To determine y, follow the property of supplementary angle:

y + 25 = 180
y = 180 - 25
y = 155°

To determine x, follow the property of the triangle,
x + 90 + 25 = 180
x = 90 - 25
x = 65

Thus, the required measure of angles x and y are 65° and 155° respectively.
