Answer:

if f(x) = 3x, g(x) = x+4, and h(x) = x²-1, Find [h•(f•g)](3)

{h • (f • g)}(3) = 440

Step-by-step explanation:

To find {h • (f • g)}(3), we need to first evaluate the innermost function, f • g, then substitute the result into the outer function, h, and finally evaluate the resulting expression at x = 3.

Let's start by finding f • g:

f • g = f(g(x))

Substitute g(x) into f(x):

f • g = f(x + 4)

Now substitute f(x) into the above expression:

f • g = 3(x + 4)

Simplify:

f • g = 3x + 12

Now we can substitute this result into h(x):

h • (f • g) = h(3x + 12)

Substitute x = 3 into the above expression:

h • (f • g) = h(3(3) + 12)

Simplify inside the parentheses:

h • (f • g) = h(9 + 12)

Simplify further:

h • (f • g) = h(21)

Now let's evaluate h(21):

h(x) = x² - 1

h(21) = (21)² - 1

Simplify:

h(21) = 441 - 1

Final result:

{h • (f • g)}(3) = 440

An ant colony is built by 200 ants. The number of ants triples each week. How many ants will be in the colony at the end of the eighth week?

Answers

To solve this problem, we need to use the formula for exponential growth:

N = N0 * 3^t

where N is the final number of ants, N0 is the initial number of ants, 3 is the rate of growth (since the number of ants triples each week), and t is the number of weeks.

We are given that there are initially 200 ants, so N0 = 200. We want to find N at the end of 8 weeks, so t = 8. Substituting these values into the formula, we get:

N = 200 * 3^8

N = 200 * 6561

N = 1,312,200

Therefore, at the end of the eighth week, there will be 1,312,200 ants in the colony.

The key's length rounded to the nearest millimeter is 6 cm.

What are the factors?

what are factorsIn mathematics, a factor is a number that divides another number without leaving a remainder.

To convert the key's length to the nearest half inch, we can use the conversion factor: 1 inch = 2.54 cm.

First, we convert 6.3 cm to inches:

6.3 cm ÷ 2.54 cm/inch = 2.48 inches

Next, we round 2.48 to the nearest half inch:

2.48 rounded to the nearest half inch is 2.5 inches

To convert the key's length to the nearest millimeter, we simply round the length in centimeters to the nearest whole number. Since there are 10 millimeters in a centimeter, rounding to the nearest millimeter means determining which whole number of centimeters is closest to the given length.

Therefore, the key's length to the nearest half inch is 2 1/2 inches.

To convert the key's length to the nearest millimetre, we can simply round 6.3 cm to the nearest whole number:

6.3 cm rounded to the nearest millimetre is 6 cm.

Therefore, the key's length rounded to the nearest millimeter is 6 cm.

The sum of two consecutive integers is 59. Write an equation that models this situation and find the values of the two integers.

Answers

Answer: The two consecutive integers are 29 and 30

==================================================

Work Shown:

x = first integer

x+1 = second integer that follows immediately after x

Consecutive integers are numbers like {4,5,6,7,...} ones that follow right after another.

Add up those expressions and set the sum equal to 59. Then solve for x

x+(x+1) = 59

2x+1 = 59

2x = 59-1

2x = 58

x = 58/2

x = 29

So 29 is the first number

x+1 = 29+1 = 30

and 30 is the next number

As a check, 29+30 = 59 which confirms our answer.

Answers

Answer:

\(3.126666666666...=3.12\overline{6}\)

Step-by-step explanation:

If the decimal number is repeating, then bar notation is used. A symbol called "bar" is used to express that type of numbers. it is placed at the top of the number that is repeating.

We have a number i.e. 3.126666666666...

$500 is invested in an account earning 7% interest compounded quarterly. Find the value
after 8 years.

Answers

The amount of the investment after 8 years will be, $4,357.64

Given, $500 is invested in an account earning 7% interest compounded quarterly.

We have to find the value of the invested amount after 8 years,

as, Amount = P(1 + r/100)^t

where, P is the amount of money invested, r is the rate of interest and t is the amount of time

Amount = 500(1 + 7/100)^(8×4)

Amount = 500(1.07)^32

Amount = 500×8.715

Amount = 4,357.635

So, the amount of the investment after 8 years will be, $4,357.64

Hence, the amount of the investment after 8 years will be, $4,357.64

y=f(x) is the particular solution to the differential equation dy/dx=(x(y-1))/4, with the initial condition of f(1)=3. write an equation for the line tangent to the graph of f at the point (1,3) and use it to approximate f(1,4)

Answers

We are given the following differential equation:

\(\frac{dy}{dx}=\frac{x(y-1)}{4}\)

Since this equation gives the value of the slope of the tangent line at any point (x,y). To determine the equation of such line we need to use the general form of a line equation:

\(y=mx+b\)

Since in a tangent line the slope is equivalent to the derivative we may replace that into eh line equation like this:

\(y=\frac{dy}{dx}x+b\)

Now we determine the value of dy/dx at the point (1,3):

\(\frac{dy}{dx}=\frac{(1)(3-1)}{4}=\frac{2}{4}=\frac{1}{2}\)

Replacing into the equation of the line:

\(y=\frac{1}{2}x+b\)

Now we replace the point (1,3) to get the value of "b":

\(3=\frac{1}{2}(1)+b\)

Solving for "b":

\(\begin{gathered} 3=\frac{1}{2}+b \\ 3-\frac{1}{2}=b \\ \frac{5}{2}=b \end{gathered}\)

Replacing into the line equation:

\(y=\frac{1}{2}x+\frac{5}{2}\)

And thus we get the equation of the tangent line.

To approximate the value of f(1.4) we replace the value x = 1.4 in the equation of the tangent line:

\(y=\frac{1}{2}(1.4)+\frac{5}{2}\)

Solving the operation:

\(y=3.2\)

Therefore, the approximate value of f(1.4) is 3.2

The rate of interest is given by the equation R = 3.5 %

What is Simple Interest?

Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

Given data ,

Let the rate of interest be represented as R

Now , the simple interest I = $ 175

The principal amount invested P = $ 2,500

The time period T = 2 years

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

Rate of Interest = (Simple Interest x 100 ) / Principal Amount x Time Period )

Substituting the values in the equation , we get

Rate of Interest R = ( 175 x 100 ) / ( 2500 x 2 )

Rate of Interest R = 17500 / 5000

Rate of Interest R = 3.5 %

Hence , the interest rate is 3.5 %

What statistical test and how many of them will need to be used to explore the difference in average cholesterol within each group before and after the treatment (i.e., how much did cholesterol level change within each group as result of the treatment)?

Answers

Answer:

The statistical test to be used is the paired t-test.

Step-by-step explanation:

The dependent t-test (also known as the paired t-test or paired-samples t-test) compares the two means associated groups to conclude if there is a statistically significant difference between these two means.

We use the paired t-test if we have two measurements on the same item, person or thing. We should also use this test if we have two items that are being measured with a unique condition.

For instance, an experimenter tests the effect of a medicine on a group of patients before and after giving the doses.

Similarly, in this case a paired t-test would be used to deter whether there was any changes in the cholesterol level within each group as result of the treatment.

Thus, the statistical test to be used is the paired t-test.
