A blacksmith has been studying vector calculus and wants to calculate the total mass of a curved metal fitting. Given that the metal fitting has a helix shape parameterized by C:[0,π] → IR3 C(t) = (cos (t), sin(t), t) And the density of the metal material is given by the function:f(x,y,z) = 22 How can the black smith calculate the total mass of the fitting and what is this mass?

Answer:

[tex]S(r)=4\pi r^2[/tex].

Step-by-step explanation:

It is given that, the surface area S of a single-celled organism may be found by multiplying 4π times the square of the radius r of the cell.  

We need to express S as a function of r.

Let r be the radius of the cell and S(r) be the surface area of single-celled organism when radius is r.

According to the question,

[tex]S(r)=4\pi \times r^2[/tex]

[tex]S(r)=4\pi r^2[/tex]

Therefore, the required function is [tex]S(r)=4\pi r^2[/tex].

Answer:

2q

Step-by-step explanation:

Product is the answer to a multiplication equation or expression. So you could put it like 2 x q but it would be easier and more understanding to do 2q...Or even 2(q).

Answer:

x=2

Step-by-step explanation:

2x+5(3x-4)=14

Distribute

2x + 15x -20 = 14

Combine like terms

17x -20 = 14

Add 20 to each side

17x-20+20 =14+20

17x = 34

Divide by 17

17x/17 = 34/17

x=2

Steps to solve:

8x - 7x + 6 = 6

~Combine like terms

x + 6 = 6

~Subtract 6 to both sides

x = 0

Best of Luck!

Answer:

0

8x0=0 7x0=0

6+0=6

Answer:

A sinusoidal model would be used

The kind of function that have consistency in the periodic rate of change is the Average rate of changes

Step-by-step explanation:

The type of model that would be used is sinusoidal model and this is because there is periodic change in the values given ( i.e the rate of changes given )

For percentage rate of changes :

starting from 0.9% there is an increase to 1.3% then a decrease to 1.1% and a further decrease to 1% before an increase to 1.3% and another decrease to 1%

For Average rate of changes:

starting from 2.9 there is a decrease to 2.4, then an increase to 3.7 and another decrease to 3.1 followed by an increase to 3.6 and a decrease back to 3.2

This relation ( sinusoidal model ) is best suited for a linear model because there is a periodic rate of change in the functions

The kind of function that have consistency in the period rate of change is the Average rate of changes

Answer:

9 is correct answer

Step-by-step explanation:

[tex] {x}^{2} - 6x - 27 \\ = {x}^{2} - 9x + 3x - 27 \\ = x(x - 9) + 3(x - 9) \\ = (x + 3)(x - 9)[/tex]

x=9

Answer:

(x - 9)(x + 3)

Step-by-step explanation:

Given

x² - 6x - 27

Consider the factors of the constant term (- 27) which sum to give the coefficient of the x- term (- 6)

The factors are - 9 and + 3, since

- 9 × 3 = - 27 and - 9 + 3 = - 6, thus

x² - 6x - 27 = (x - 9)(x + 3)

Answer:

g(x) = 5/3 * f(x)

Step-by-step explanation:

We want to find the equation represents g(x) as a translation of f(x).

From the graph, the y = f(x) function curve has the following observations,

- At x = 0, y = f(0) = 30

- At x = 10, y = f(10) = 36

Similarly, from the graph, the y = g(x) function curve has the following observations,

- At x = 0, y = g(0) = 50

- At x = 10, y = g(10) = 60

From those coordinates on the graph, we can see that;

f(0) = 30 and g(0) = 50

It means that for us to make g(x) as a translation of f(x), g(0) = fraction * f(0)

Fraction = g(0)/f(0) = 50/30 = 5/3

Thus;

g(x) = 5/3 * f(x)

Let's confirm with the second coordinate;

Thus;

g(10) = 5/3 * f(10)

g(10) = 5/3 * 36

g(10) = 60

This value is same as what is on graph, thus we can conclude that;

The equation represents g(x) as a translation of f(x) is; g(x) = 5/3 * f(x)

Answer:

[tex]Second = \$213876[/tex]

Step-by-step explanation:

Given

Highest Winning = $262,743

Second Highest Winning = 81.4012% of the first

Required

Determine the value of the second highest winning

Recall that

[tex]Second\ Highest\ Winning = 81.4012\%\ of\ the\ first[/tex]

Substitute $262,743 for the first highest winning

[tex]Second = 81.4012\%\ of\ \$262,743[/tex]

[tex]Second = 81.4012\%\ * \$262,743[/tex]

[tex]Second = \$213875.954916[/tex]

Approximate

[tex]Second = \$213876[/tex]

Hence, the second highest winning is approximately $213876

Answer:

286 students attended

148 non students attended

Step-by-step explanation:

Given

[tex]Tickets = 434[/tex]

[tex]Students = \$4.00[/tex]

[tex]Non-Students = \$6.00[/tex]

[tex]Total = \$2032.00[/tex]

Solving (a): Number of students

Represent students with S and non students with N

So:

[tex]S + N = 434[/tex] --- (1)

[tex]4S + 6N = 2032[/tex] --- (2)

Make N the subject of formula in (1)

[tex]N = 434 - S[/tex]

Substitute 434 - S for N in (2)

[tex]4S +6(434 - S) = 2032[/tex]

Open Bracket

[tex]4S + 2604 - 6S = 2032[/tex]

Collect Like Terms

[tex]4S - 6S = 2032 - 2604[/tex]

[tex]-2S = -572[/tex]

Divide through by -2

[tex]S = 286[/tex]

Hence; 286 students attended

Solving (b):

Recall that

[tex]N = 434 - S[/tex]

[tex]N = 434 - 286[/tex]

[tex]N = 148[/tex]

148 non students attended

Answer:

-4

Step-by-step explanation:

So we have the function:

[tex]h(x)=-3x-4[/tex]

To find h(0), substitute 0 for x. Thus:

[tex]h(0)=-3(0)-4[/tex]

Multiply:

[tex]h(0)=0-4[/tex]

Subtract:

[tex]h(0)=-4[/tex]

And we're done!

Answer: 0.03538944

Step-by-step explanation:

Given, The accuracy of missile = 96%

i.e. The probability that it will hit the shot = 0.96

Probability of missing the shot = 1-0.96= 0.04

Now, each missile is independent of other.

Therefore, the probability only the second one misses = (probability that first will hit the shot) x (probability that second one misses ) x (probability that third will hit the shot)x (probability that fourth will hit the shot)

Thus, the probability only the second one misses is [tex](0.96)(0.04)(0.96)(0.96)=0.03538944[/tex]

Hence, the required probability = 0.03538944

Answer: There are 100 boys at the concert

Step-by-step explanation:

If the the ratio of  boys to girls is 2:5 and and there are 250 girls  then a number was multiplied by 5 to get 250  and that number needs to be multiply by 2  to find the number of boys.

So to find that number we will divide 250 by 5.

250/ 5 = 50  

50 * 2 = 100

Answer:

2/7 or 2 over 7

Step-by-step explanation:

4/14 can be simplified. We know this because both 4 and 14 can be divided by 2. 4 divided by 2 = 2 and 1 divided by 2 = 7, thus the answer is 2 over 7.

3x - 4 = -2x + 11

5x - 4 = 11

5x = 15

x = 3

3(3) - 4 = 9 - 4 = 5 = y

(3, 5)

Answer:

1.)y=3x-4=5

2.)y=4x-1=7

Answer: -4/10

Step-by-step explanation:

Since we are finding the slope, we have to do the rise over run strategy. In this case, rise (y) are the numbers  -3 and 1 and the run (x) is the numbers -6 and 4. After that, we subtract them. So, -3 - 1 and -6 - 4. We get -4 over -10 (or - 4/10) which is your slope.
