Differentiate the following equation

Mathematics
1 answer:
Bingel [31]2 years ago
4 0

Answer:

\frac{dy}{dx} = \frac{4}{1-x}

Step-by-step explanation:

    y = 3 - 4ln(1 - x)

⇒ \frac{dy}{dx} =3\frac{d}{dx} -4ln(1-x)\frac{d}{dx}

⇒ \frac{dy}{dx} =0 -4ln(1-x)\frac{d}{dx}

⇒ \frac{dy}{dx} =0 -4(\frac{1}{1-x})\times-1

⇒ \frac{dy}{dx} = \frac{4}{1-x}

Ivenika [448]

From what I'm understanding of these questions, the biggest thing you need to answer these is the formulas for cylinders and triangular prisms. I'm not sure what the quantities are for either question so I'm going to work with made up numbers to give examples for the formulas. For number 2 with the cylinder, let's consider the formula first:

π × r2 × h    <em>OR    </em>pi (3.14) times radius squared times height

If you have the height and you have pi, all you need to take is the doubled radius (aka multiply it by 2) and plug that back into the formula. For the sake of an example, I'm going to make up the number 2 for the radius and 6 for the height. Here's what that would look like:

r = 2; double it, resulting in 4

pi x 4^2 x 6

3.14 x 16 x 6

= 301.44

Work with the actual numbers you have and you're good to go.

For number 3, reducing something by 1/2 means dividing by 2. Let's consider the formula and then work through another example:

1/2 x b x h x l   <em>OR </em>   1/2 times base times height times length

For the sake of an example, I'll use 10 for the height, 15 for the base, and 20 for the length:

h = 10; reduce by 1/2, resulting in 5

1/2 x 15 x 5 x 20

= 750

Plug in your actual quantities, and remember your volume units. Hope this helps!

Which expression has a value of StartFraction 1 Over 36 EndFraction? (StartFraction 1 Over 108 EndFraction) cubed (StartFraction
IrinaVladis [17]

Answer:

(1/6)^2

Step-by-step explanation:

We want to find the fraction that is equivalent to 1/36.

Let us look at each of them individually:

a. (\frac{1}{108})^3 = \frac{1}{1259712}

b. (\frac{1}{9})^4 =  \frac{1}{6561}

c. (\frac{1}{6})^2 =  \frac{1}{36}

d. (\frac{1}{5})^2 = \frac{1}{25}

Therefore, the correct answer is c.

Please help!!!!!!!!!!!!!!!!!!!!!!!!
brilliants [131]

Answer: P=47 inches

Step-by-step explanation:

First, you have to find the other side lengths. Two of the sides are equal to 20 because this is a rectangle. The first blank would be 20 because 20 times the other side length is equal to 70. Then you would divide 70 by 20 which would equal x. x would equal 3.5 in. Then the perimeter would be:

2(20)+2(3.5)=P

P=47 inches
