f (x) = cos(πx/2)

Answers

Answer: The derivate is f'(x) = -sin(πx/2)*(π/2)

Step-by-step explanation:

We want the value of the derivate at each point marked:

As you may know, the derivate of cos(x) is equal to -sin(x)

And in our case:

f(x) = cos(πx/2)

f'(x) = -sin(πx/2)*(π/2)

Where the rule used is that the derivate of f(g(x)) is equal to f'(g(x))*g'(x)

Now, as you may see, in both the marked points the curve changes of direction, so the tangent line in that point must be zero, letsinput the values of x in the derivate and see if this is true:

f'(0) = -sin(π*0/2)*(π/2) = -sin(0)*(π/2) = 0

f'(2) = -sin(π*2/2)*(π/2) = -sin(π)*(π/2) = 0

So this makes sense.

If you subtract the death rate from the birth rate of a population, you will calculate what?

A. the arithmetic growth rate.
B. the expansion rate.
C. the carrying capacity.
D. the intrinsic growth rate.


Answers

The best and most correct answer among the choices provided by your question is the third choice or letter C.

If you subtract the death rate from the birth rate of a population, you will calculate the carrying capacity.


I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Subtracting the death rate from the birth rate of a population calculates its intrinsic growth rate, expressed as dN = (b - d)N, where 'r' is the intrinsic rate of increase.

When you subtract the death rate (D) from the birth rate (B) of a population, you calculate the intrinsic growth rate of the population. The birth rate is typically expressed on a per capita basis, shown as B = bN, where 'b' represents the per capita birth rate and 'N' is the number of individuals in the population. Similarly, the death rate is expressed as D = dN, where 'd' is the per capita death rate. To find the population growth rate at a specific point in time, differential calculus is used to obtain an instant-specific measurement:

dN = (b - d)N

This formula simplifies the relationship between the birth and death rates, where 'b - d' is substituted with 'r', representing the intrinsic rate of increase. Therefore, the correct answer to the student's question is D. the intrinsic growth rate.

Three water pipes are used to fill a swimming pool. The 1st pipe alone takes 8 hours to fill the pool, the 2nd pipe alone takes 12 hours to fill the pool, and the 3rd pipe takes 24 hours to fill the pool. If all 3 pipes are opened at the same time, how long will it take all 3 together to fill the pool?

Answers

For 4 h. The first pipe fills the whole pool for 8 hours so from here we see that it fills 1/8 each hour. The second pipe fills it for 12 hours so it fills 1/12 each hour. The third pipe fills it for 24 hours so it fills 1/24 each hour. Now the three of them together fill 1/8 + 1/12 + 1/24 of the pool each hour. That equals: 1st pipe 3/24 of the pool each hour, the 2nd pipe 2/24 of the pool each hour and the 3rd 1/24 each hour. So, the three pipes together fill 3/24 + 2/24 + 1/24 each hour. That's 6/24 of the pool each hour.
1st hour: 6/24
2nd hour: 12/24
3rd hour: 18/24
4th hour: 24/24

for the parallelogram, if m<2+5x-28 abd m<4=3x-10, find m< 3. ...?

Answers

Final answer:

After finding the value of x by equating m<2 and m<4, we calculate m<4 and then use the property of supplementary angles in a parallelogram to find that m<3 is 163 degrees.

Explanation:

To solve for m<3 in the parallelogram with m<2 = 5x - 28 and m<4 = 3x - 10, we first find the value of x. Given that opposite angles in a parallelogram are equal (m<2 = m<4), we set the two equations equal to each other and solve for x:

5x - 28 = 3x - 10

5x - 3x = 18

2x = 18

x = 9

Now that we have the value of x, we can substitute it into the equation for either angle to find the measure of that angle. Since m<4 = 3x - 10:

m<4 = 3(9) - 10 = 27 - 10 = 17

In a parallelogram, adjacent angles are supplementary, meaning they add up to 180 degrees. Therefore, to find m<3, we subtract m<4 from 180 degrees:

m<3 = 180 - m<4

m<3 = 180 - 17 = 163

Thus, m<3 in the parallelogram is 163 degrees.

Final Answer:

The measure of angle 3 in the parallelogram is [tex]\( m\angle 3 = 2x - 18 \).[/tex]

Explanation:

In a parallelogram, opposite angles are equal. Therefore, we can set up an equation based on the given angle measures:

[tex]\[ m\angle 2 + m\angle 3 = 180^\circ \][/tex]

Substitute the given expressions for[tex]\( m\angle 2 \) and \( m\angle 4 \):[/tex]

[tex]\[ (2 + 5x - 28) + (3x - 10) = 180 \][/tex]

Combine like terms:

[tex]\[ 5x + 3x - 28 - 10 + 2 = 180 \][/tex]

[tex]\[ 8x - 36 = 180 \][/tex]

Add 36 to both sides:

[tex]\[ 8x = 216 \][/tex]

Divide by 8:

[tex]\[ x = 27 \][/tex]

Now that we have the value for x, substitute it into the expression for \( [tex]m\angle 3 \):[/tex]

[tex]\[ m\angle 3 = 2(27) - 18 \][/tex]

[tex]\[ m\angle 3 = 54 - 18 \][/tex]

[tex]\[ m\angle 3 = 36 \][/tex]

Therefore, the measure of angle 3 in the parallelogram is [tex]\( m\angle 3 = 36^\circ \).[/tex]

On solving the linear equations given, we get the values as 5, 2, -3, 11 and -11 for the equations  7r - 7 = 2r + 18, 2x + 12 = 18 - x, 8x - 3 = 15x + 18, 6y - 6 = 4y + 16 and 3(x - 4) = 5(x + 2) respectively.

What is Linear Equation?

Linear equations are equations which includes one or more variables and constants with the highest degree of the variable being 1.

1. 7r - 7 = 2r + 18

  Taking the variables on one side and constants on the other side,

  7r - 2r = 18 + 7

  5r = 25

  r = 5

2. 2x + 12 = 18 - x

   2x + x = 18 - 12

   3x = 6

   x = 2

3. 8x - 3 = 15x + 18

   8x - 15x = 18 + 3

   -7x = 21

   x = -3

4. 6y - 6 = 4y + 16

   6y - 4y = 16 + 6

   2y = 22

   y = 11

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

   Multiplying each term inside the bracket by the term outside,

   3x - 12 = 5x + 10

   3x - 5x = 10 + 12

   -2x = 22

   x = -11

Hence we got the values of the unknowns as 5, 2, -3, 11 and -11 for the equations  7r - 7 = 2r + 18, 2x + 12 = 18 - x, 8x - 3 = 15x + 18, 6y - 6 = 4y + 16 and 3(x - 4) = 5(x + 2) respectively.

Or

[tex] \frac{ ln(y) }{ln(3) } = x[/tex]

Taking logarithm of both sides to base e, we obtain;

An electrician charges a $50 house call fee and $65 per hour for the work. Which algebraic expression represents this situation to represent the total cost for h hours of work?

Answers

$50 house call fee is a FIXED constant. There is no variable it multiplies to. $65 is attached to h because it represents how much you earn PER hour.

Thus:
$50+$65h
Final answer:

The algebraic expression is Total Cost = 65h + 50.

Explanation:

To represent the total cost for h hours of work, we need to consider the house call fee of $50 and the hourly rate of $65. The total cost will depend on the number of hours worked.

We can calculate the total cost using the expression: Total Cost = (Hourly Rate * Number of Hours) + House Call Fee.

Therefore, the algebraic expression that represents this situation is: Total Cost = 65h + 50.

Answers

the answer is 10.the unknown number is 25.

To find 40% of the number where 6 is 24%, we first determine the whole number by dividing 6 by 0.24 to get 25. Then we calculate 40% of 25, which is 10.

If we know that 6 is 24% of a number, we can find the whole number by dividing 6 by 0.24. Once we have the full number, we can calculate 40% of it. Let's do the calculation step by step.

Calculate the whole number using the given percentage: Whole number = 6 / 0.24.

Perform the division to find the whole number: Whole number = 25.

Calculate 40% of the whole number: 40% of 25 = 0.40 * 25.

Perform the multiplication to find 40% of the number: 40% of 25 = 10.

Therefore, 40% of the same number is 10.
