Answer:

4939.22 feet cubed.  

Step-by-step explanation:

The formula for the volume of a cylinder is V=3.14*r^2*h

First we square the raidus, which is 11 in this problem.  11 squared is 121.

Next we multiply everything together.

3.14*121 is 379.94.  Then, 379.94 * the height, which is 13, is 4939.22.

Since our answer is already rounded to the nearest hundredth, the answer to this problem is 4939.22

Answer:

The distance is 2 units.

Step-by-step explanation:

Given Data:

Point 1: (-3, -5)

Point 2: (-3, -7)

Distance Formula:

\(\sqrt{(x2 - x1)^{2} + (y2-y1)^{2} }\)

Substitute the given values and solve:

\(\sqrt{(-3 --3)^{2}+(-7--5)^{2} }\)

\(\sqrt{0^{2} +(-2)^{2} }\)

\(\sqrt{0+4}\)

\(\sqrt{4}\)

= 2

Answer = 2

Answer:

Number 3 is

Number 4 is 5(4x+7y)

Step-by-step explanation:

Step-by-step explanation:

Hey there!

The length is 40 cm more than breadth.

Sp let the breadth be x.

So, length will be 40+x

Now, we know that Perimeter of a rectangle is 2(Length+Breadth)

We can write that

380 cm = 2(40+x+x)

190 = 40+2x

2x = 150

x = 75 cm.

So, breadth is 75 cm.

And length is 75+40 = 115 cm.

Hope it helps:)

Answer:

W= 75  L= 115

Step-by-step explanation:

3.8m= 380cm

Perimeter= 380cm

Perimeter formula: 2(L+W)

L= length W= width

The length in the problem equals 40cm more then the width. so the length equals (w+40) or (40+w). now subsitute that into the perimeter formula.

2(40+W+W)=380

Now solve for W

2(40+W+W)=380

Divide by 2 on each side, to get rid of it on the left (like below)

40+W+W= 190

subtract 40 off both sides

2w= -40+190

Divide by 2 on both sides

2w=150

W= 75

Since the width is 75, this means that the length is 40 more than 75, therfore

L= 75+40=115

Answer:

37.5

Step-by-step explanation:

cosФ = \(\frac{A}{H}\)

cos(33°35') = \(\frac{m}{45}\)

m = 45 × cos(33°35')

m = 37.5 (1d.p.)

3. 4,4.5

Step-by-step explanation:

The sun is in the middle of both numbers, and there is a 1 gap, So we make it 1/2. To do that for each problem you add 0.5 for each answer in the middle.

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Answer:

v=-1/2

Step-by-step explanation:

v=u+at

v=2+(-5*1/2)

v=2-5/2

v=4-5/2

v=-1/2

To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.
