I suspect 4/2 should actually be 4/3, since 4/2 = 2, while 4/3 would make V the volume of a sphere with radius r. But I'll stick with what's given:

[tex]\displaystyle \frac{dV}{dr} = \lim_{h\to0} \frac{2\pi(r+h)^3-2\pi r^3}{h}[/tex]

[tex]\displaystyle \frac{dV}{dr} = 2\pi \lim_{h\to0} \frac{(r^3+3r^2h+3rh^2+h^3)- r^3}{h}[/tex]

[tex]\displaystyle \frac{dV}{dr} = 2\pi \lim_{h\to0} \frac{3r^2h+3rh^2+h^3}{h}[/tex]

[tex]\displaystyle \frac{dV}{dr} = 2\pi \lim_{h\to0} (3r^2+3rh+h^2)[/tex]

[tex]\displaystyle \frac{dV}{dr} = 2\pi \cdot 3r^2 = \boxed{6\pi r^2}[/tex]

In Mathematica, you can check this result via

Step-by-step explanation:

The lengths will form a right triangle if the squares of the two shortest legs total the square of the longest. The square of a root is the number under the radical, so you're looking to see if the two smallest numbers under the radicals total the largest number under the radical.

  A: 22 +88 = 110 . . . . . a right triangle

  B: 66 +99 = 165 ≠ 176 . . . . an obtuse triangle

  C: 22 +110 = 132 ≠ 121 . . . . an acute triangle

  D: 66 +77 = 143 ≠ 154 . . . . an obtuse triangle

_____

Additional comment

The largest angle is opposite the longest side. If the longest side is too long for the triangle to be a right triangle, then the opposite angle is larger than 90°, and the triangle is obtuse. If the longest side is too short for a right triangle, then the triangle is acute.

Answer:

x = 4 + sqrt 5

x = 4 - sqrt 5

Step-by-step explanation:

(X-4)^2 = 5

X - 4 = + - sqrt 5

X = 4 + sqrt 5 and

X = 4 - sqrt 5

Answer:

Step-by-step explanation:

Take the square root of each side of the equation to set up the solution for x

[tex](x-4)^{2*\frac{1}{2} } =[/tex] ±[tex]\sqrt{5}[/tex]

Remove the perfect root factor x - 4 under the radical to solve for x.

x - 4 = ±[tex]\sqrt{5}[/tex]

The complete solution is the result of both the positive and negative portions of the solution.

First, use the positive value of the ± to find the first solution.

[tex]x-4=\sqrt{5}[/tex]

Add 4 to both sides of the equation.

[tex]x=\sqrt{5} +4[/tex]

Next, use the negative value of the ± to find the second solution.

[tex]x-4=-\sqrt{5}[/tex]

Add 4 to both sides of the equation.

[tex]x=-\sqrt{5} +4[/tex]

The complete solution is the result of both the positive and negative portions of the solution.

[tex]x=\sqrt{5} +4,-\sqrt{5} +4[/tex]

Answer:

300+400+500=1200

Step-by-step explanation:

given total paid $2400

spend $1200 on a rent (half of his paid)

so rest he spend as a ratio of 3:4:5=1200

let x as a amount he using to pays rest of the bills so

3x+4x+5x=1200

12x=1200

x=1200/12

x=100

so he spends 3x=300

4x=400

5x=500

Answer:

  8 + (-3) = 5

Step-by-step explanation:

A number line offers a suitable model. +8 is represented by a segment extending from 0 to 8. -3 is represented by a segment extending from 0 to -3. The addition of those numbers is modeled by placing those segments end-to-end. In the attachment, we have shown -3 placed so it starts at the end of +8. The other end of -3 lies at the sum: 5.

  8 + (-3) = 5

Answer:

The answer is y=-x+9.

The first thing to do is find where the line intercepts the y-axis, which is at positive 9 so you'll add a +9 to the end of your equation. Next you find the slope and since it's going down left to right, you know it is a negative. Now slope is found by change in y divided by change in x. And since both change and y and change in x are both 1, 1/1 is 1. And since you know it's negative that means the slope is -x. Altogether you get y= -x+9

The sample mean weight, from this random sample of 135 pigs, fall within the confidence interval. (Option A: yes)

Suppose that we have:

Then the confidence interval is obtained as

[tex]\overline{x} \pm Z_{\alpha /2}\dfrac{\sigma}{\sqrt{n}}[/tex]

[tex]\overline{x} \pm Z_{\alpha /2}\dfrac{s}{\sqrt{n}}[/tex]

For this case, we work with sample standard deviation(you can choose even population standard deviation, it won't matter as both are not given here).

We're provided that:

Since the formula for limits of confidence interval is:

[tex]\overline{x} \pm Z_{\alpha /2}\dfrac{s}{\sqrt{n}} = \overline{x} \pm 1.645\dfrac{s}{\sqrt{135}}[/tex]

That has:

[tex]\text{Lower limit} = 75 = \overline{x} - 1.645\dfrac{s}{\sqrt{135}}\\\\\text{Upper limit} = 90 = \overline{x} +1.645\dfrac{s}{\sqrt{135}}\\\\[/tex]

Thus, we get:

Adding both the equations, we get:

[tex]165 = 2\overline{x}\\\\\overline{x} = 82.5 \: \rm pounds[/tex]

That is between 75 and 90 pounds.

Thus, the sample mean weight, from this random sample of 135 pigs, fall within the confidence interval. (Option A: yes)

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.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as C

Now , the value of C is

The selling price of the article is given as $440, and we know that the shopkeeper incurs a loss of 12% on the sale

Selling price = Cost price - Loss

Substituting the given values, we get

$440 = C - 0.12C

Simplifying this equation, we get:

$440 = 0.88C

Dividing both sides by 0.88, we get:

C = $500

Hence , the cost price of the article is $500
