Answer:

  about 2.758 cm/s

Step-by-step explanation:

You want the rate of change of a cylinder's radius, when its height is 33 cm increasing at 2 cm/s, and its volume is 403 cm³ increasing at 1152 cm³/s.

The volume of a cylinder is given by the equation ...

  V = πr²h

Solving for the radius gives ...

  r = √(V/(πh))

Differentiating, we have ...

  [tex]r'=\dfrac{1}{\sqrt{\pi}}\left(\dfrac{1}{2}V^{-\frac{1}{2}}h^{-\frac{1}{2}}V'-\dfrac{1}{2}V^{\frac{1}{2}}h^{-\frac{3}{2}}h'\right)=\dfrac{hV'-Vh'}{2h\sqrt{\pi Vh}}[/tex]

Filling in the values V = 403, V' = 1152, h = 33, h' = 2, we have ...

  r' = (33·1152 -403·2)/(2·33·√(π·403·33)) = 37210/(66√(13299π))

  r' ≈ 2.758 . . . . . cm/s

The rate of change of the radius is about 2.758 cm/s.

What is ideal gas law?

The equation of state for an ideal gas, in theory, is known as the ideal gas law. Even though it has a number of shortcomings, it provides a good approximation of the behavior of several gases under various circumstances. Theoretical point particles that move randomly and only collide in elastic ways make up an ideal gas.

Using the ideal gas equation PV=nRT, where n is the number of moles, it is possible to determine the volume that will be present at STP as follows.

n= PV/RT

p=0.974 atm

V=6.0  L

R = 0.0821  L.atm/k.mol

T=  35 +273= 308k

n=  (0.974 atm  x  6.0 L)/( 0.0821 L.atm/k.mol  x 308 k)=  0.178 moles

STP  1 mole=  22.4 L  what obout  0.23 moles

For choosing 1 flavor of ice cream from 4, we have 4 ways.

Now, we need to choose 3 different toppings from the given 6.

This can be done in 6C3 ways

6C3 = 6! / (3! × 3!)

y - 9 = 1(x - 15) is the required equation for the tangent.

Equations come in two varieties: identities and conditional equations.

All possible values of the variables result in an identity.

Only certain combinations of the variables' values make a conditional equation true.

Two expressions joined by the equals symbol ("=") form an equation.

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign.

A formula would be 3x - 5 = 16, for instance.

When this equation is solved, we discover that the value of the variable x is 7.

So, the equation of the tangent is:

First, with respect to t, differentiate the function as follows:

dx/dt = d(9t² + 6)/dt

dx/dt = 18t

Like this, we have:

dy/dt = d(6t³ + 3)/dt

dy/dt = 18t²

Now, we will obtain:
dy/dx = 18t²/18t

dy/dx = t

We know that (15, 9) occurs on the curve, so we got:

d(9t² + 6)/dt and d(6t³ + 3)/dt ⇒ t = ±1 and t = 1 ⇒ t = 1

So, (15, 9) is the slope.

y - 9 = 1(x - 15) is the equation of the tangent.

Therefore, y - 9 = 1(x - 15) is the required equation for the tangent.

The unit rate per batch of cookies is 2.75 as Lennon uses 5 1/2 cups of flour for every 2 batches of cookies she bakes.

To calculate the unit rate, divide the denominator by the numerator so that the denominator equals 1. For example, if 50 kilometers are reached in 5.5 hours, the unit rate is 50 kilometers/5.5 hours = 9.09 kilometers per hour.

When expressed as a fraction, a unit rate has a denominator of one unit. To write a rate as a unit rate, divide the rate's numerator and denominator by the rate's denominator.

Based on the given conditions, formulate:

(5 1/2)/2

We have to find the common denominator and write the numerators above the common denominator.

(((5×2)/2)+(1/2))/2

Now, we have to calculate the product or quotient:

((10/2)+(1/2))/2

Now, write the numerators over common  denominator,

((10+1)/2)/2

Then, calculate the sum or difference:

Answer:  9 hours

Step-by-step explanation:

here are a couple of things to notice here. You don’t have a starting temperature, so that will be an unknown. I will call it S.

The next thing to notice is that the current temperature (C) at any given time is just the starting temperature minus 4 times the number of hours (H) that have passed since 1 PM.

C = S – 4*H

We want to solve this for H when the current temperature (C) is -1.

-1 = S – 4*H

You can rearrange this by adding 4*H to both sides and adding 1 to both sides:

4*H = S + 1

Then you divide both sides by 4

H = (S+1)/4

This will tell you the number of hours PAST 1 PM that it takes to get to -1 degrees. Of course, you need to know the starting temperature, S, in order to get a numeric answer.

Let’s check this with an example. If the starting temperature were exactly 4 degrees above -1, then it should take exactly 1 hour. So let S = -1 + 4 = 3. If you plug 3 in for S, you do see that H becomes 1 hour PAST 1 PM (2 PM).

We study sets and their characteristics in the area of mathematical logic known as set theory. A set is a collection of things or a group of things. These things are frequently referred to as elements or members of a set. A set is, for instance, a group of cricket players. A set is a clearly defined collection of things or people, as we already learnt in the introduction. Numerous examples from everyday life, such as the number of rivers in India and the colors in a rainbow, can be used to relate sets.

Given,

Total no of people =116

No of people visiting any of the three places = total - people visiting none of the places

No of people visiting only Gateway arch = total people visiting gateway arch - (people visiting all the three +  people visiting Gateway ans museum butnot zoo +people visiting gateway and zoo butnot museum)

Part B: The maximum number of pens and pencils the club can purchase is 120 and 600 respectively.

The stated values in the questions are-

Cost of one pen = $0.75

Let total number of pens be x.

Cost of one pencil = $0.15

Let total number of pencils be y.

Total cost (pens and pencils) = $90

Total cost = (Cost of one pen) x (Number of pens)  +  (Cost of one pencil)x(Number of pencils)

The equation modelling number of club pens and pencils is:

0.75x  +  0.15y    =   90

For the greatest number of pens ;

0.75x  = 90

x  =  90/0.75

x  =  120

Thus, the greatest number of pens bought by club is 120.

For greatest number of pencils;

0.15y = 90

y  =  90/0.15

By definition of slope , we have seen that Slope = 4/3 and 4/3 = 16/12

The slope of a line is basically a measure of its steepness. Mathematically, the slope is calculated as rise over run.

To find the slope, we divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. This is change in y divided by change in x.

From definition of slope, we know that;

Slope between line D and E is; Slope = 4/3

Similarly, by definition of slope, we know that;

Slope between line D and E is; Slope = 16/12

Now, 16/12 can be reduced to 4/3 and as such;
