Show Work. This Is A BC Calculus Problem.

Answers

Answer 1

Answer:

D.

Step-by-step explanation:

Recall that the limit definition of a derivative at a point is:

[tex]\displaystyle{\frac{d}{dx}[f(a)]= f'(a) = \lim_{x \to a}\frac{f(x)-f(a)}{x-a}}[/tex]

Hence, if we let f be ln(x + 1) and a be 1, this yields:

[tex]\displaystyle f'(1)= \lim_{x \to 1}\frac{\ln(x+1)-\ln(2)}{x-1}}[/tex]

Hence, the limit is equivalent to the derivative of f at x = 1 or f’(1).

In conclusion, our answer is D.

The compressive strengths of 40 concrete cylinders have an estimated mean of 60.14 MPa and standard deviation of 5.02 MPa. Assuming the strength to be Normally distributed, what is the probability that 10 cylinders will each have strengths between 45 and 75 MPa?

Answers

Answer: 0.9972

Step-by-step explanation:

Let x be a random variable that represents the strength of concrete cylinders.

Given: The compressive strengths of 40 concrete cylinders have an estimated mean[tex](\mu)[/tex] of 60.14 MPa and standard deviation[tex](\sigma)[/tex] of 5.02 MPa.

The probability that 10 cylinders will each have strengths between 45 and 75 MPa :

[tex]P(45<\overline{x}<75)=P(\dfrac{45-60.14}{5.02}<\dfrac{\overline{x}-\mu}{\sigma}<\dfrac{75-60.14}{5.02})\\\=P(-3.016<z<2.96)\\\\=P(z<2.96)-P(z<-3.016)\\\\=P(z<2.96)-(1-P(z<3.016))\\\\=0.9985-(1-0.9987)\ \ \ [\text{by p-value table}]\\\\= 0.9972[/tex]

Hence, The required probability = 0.9972

Sam is handing out advertisements for an upcoming event. He starts with a box of 5,000 advertisements and hands out 12 advertisements per minute, on average. Which of the following equations best models the relationship between the amount of time t, in minutes, Sam spends handing out advertisements and the number of advertisements, n, remaining? A t = 5,000n - 12 B n = 5,000t - 12 C t = 5,000 - 12n D n = 5,000 - 12t ​

Answers

Answer:

n = 5,000 - 12t ​

Step-by-step explanation:

Sam is handing out advertisements for an upcoming event.

No of advertisements = 5000

No of advertisements per minute is 12.

We need to find the equation that best models the relationship between the amount of time t, Sam spends handing out advertisements and the number of advertisements, n, remaining.

5000 is fixed and there are 12 advertisements per minute. Let the equation is given by :

n = 5,000 - 12t ​

Hence, the correct option is (d).

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Let, The savings and his work be denoted by a positive amount and his spending be donated by a negative amount.

So, From the information given his savings of $20.50 and his work of mowing the lawn for $7.50 and washing a car for $3.75 should be added which is,

= $(20.50 + 7.50 + 3.75).

= $31.75

Now, we'll subtract all his spending,

= $(31.75 - 5.25 18.75).

= $7.75.

The sum of the ages of Peter and Paul is 24. Five years ago their respective ages were in the ratio 3:4. How old will they be in three years time?​

Answers

Answer:

16 and 14 years old.

Step-by-step explanation:

Let their ages be x and y years, then

x + y = 24 .......... (1)

Also from the given information

(x - 5)/ (y - 5) = 3/4

3y - 15 = 4x - 20

3y - 4x = -5

Multiplying equation (1) by 3:

3y + 3x = 72

Subtracting these last 2 equations:

-7x = -77

x = 11.

So y = 24 - 11 = 13.

So in 3 years time they will be 16 and 14.

Answer:

Peter would be 14. Paul would be 16

Step-by-step explanation:

Variable labels:

Peter = m, Paul = n

m + n = 24

(m - 5) : (n- 5) = 3:4

The ratio 3:4 in fraction form is [tex]\frac{3}{4}[/tex]

The ration of (m - 5) : (n- 5) in fraction form is [tex]\frac{m - 5}{n - 5}[/tex]

[tex]\frac{m-5}{n-5} = \frac{3}{4}[/tex]

Cross multiply:

4(m - 5) = 3(n - 5)

4m - 20 = 3n - 15

4m = 3n + 5

Find the value of m first:

4m = 3n + 5

m = [tex]\frac{3n + 5}{4}[/tex]

Now going back to the equation m + n = 24, substitute m with [tex]\frac{3n + 5}{4}[/tex] :

m + n = 24

[tex]\frac{3n + 5}{4}[/tex] + n = 24

Solve for n:

[tex]\frac{3n + 5}{4}[/tex] + n = 24

[tex]\frac{3n}{4} + \frac{5}{4}[/tex] + n = 24

[tex]\frac{7n}{4} +\frac{5}{4}[/tex] = 24

[tex]\frac{7n}{4} = \frac{91}{4}[/tex]

n = 13 (Paul's age)

Solve for m:

m + n = 24

m + 13 = 24

m = 11 (Peter's age)

After three years, Peter would be 11 + 3 = 14 years old and Paul would be 13 + 3 = 16 years old.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

Z is the centroid of triangle.

The centroid is the centre point of the object. The point in which the three medians of the triangle intersect is known as the centroid of a triangle.

WR=87 SY=39 and YT=48

We need to find WS,WY,WZ,ZR,ZT and YZ

WS=39

As WS=WR

WY=WS+SY

WY=39+39=78

WZ=58

ZR=WR-WZ

ZR=87-48=29

ZT=16

YZ=YT-ZT

=48-16=32

YZ=32

Hence, the measures are WS=39, WY=78, WZ=58, ZR=29, ZT=16 and YZ=32

Some of the steps in Liam solution to 3. 5 (1.25x + 0.5) = 10.5 are shown complete the boxes with reasons for lines 2 and 4 of Liam solution

Answers

Answer:

x = 2

Step-by-step explanation:

Given the equation;

3. 5 (1.25x + 0.5) = 10.5

Open the parenthesis

3.5(1.25x) + 3.5(0.5) =10.5

4.375x + 1.75 = 10.5

4.375x + 1.75 -1.75= 10.5-1.75

4.375x = 8.75

Divide both sides by 4.375

4.375x/4.375 = 8.75/4.375

x = 2

Hence the solution to the equation is 2
