If p and q vary inversely and p is 29 when q is 16, determine q when p is equal to 116.

Answers

Answer:

q = 4

Step-by-step explanation:

given p and q vary inversely then the equation relating them is

p = [tex]\frac{k}{q}[/tex] ← k is the constant of variation

to find k use the condition p = 29 when q = 16 , then

29 = [tex]\frac{k}{16}[/tex] ( multiply both sides by 16 )

464 = k

p = [tex]\frac{464}{q}[/tex] ← equation of variation

when p = 116 , then

116 = [tex]\frac{464}{q}[/tex] ( multiply both sides by q )

116q = 464 ( divide both sides by 116 )

q = 4

Wendi is 6 years older than Zaviel. The sum of their ages is 30. Which of these systems of equations can be used to find Wendi's age (w) and Zaviel's age (z)?

Answers

For Wendy’s age you can’t do 30-6=24 and then for Zaviel’s you can do 24-6=18 so Wendy is 24 years old and Zaviel is 18 years old.
30-6=w
W-6=z
30-6=24(w)
24-6=18(z)

The system of equations for the ages of Wendi and Zaviel can be obtained as  x = y + 6 and x + y = 30 respectively.

What is a system of linear equations?

A system of linear equations is a group of  equations having same number of variables and degree.

For the n number of variables n number of equations are required.

On the basis of number of solutions a system of equations can be classified as consistent and inconsistent.

Suppose the age of Wendi and Zaviel be x and y respectively.

Then, the equation for their age can be written as,

x = y + 6

And, the equation for the sum of ages is given as,

x + y = 30

Hence, the equations that represent the given case are x = y + 6 and x + y = 30 respectively.

The area of a sector of a circle with a central angle of 6pi/5 rad is 31 km2.

Find the radius of the circle.
r =
km

Answers

Answer:

  4.06 km

Step-by-step explanation:

The area of the sector of a circle is given by the formula ...

  A = 1/2r²θ

Filling in the given information, we have ...

  31 km² = 1/2(r²)(6π/5)

Solving for r gives ...

  r² = (31 km²)(5/(3π)) ≈ 16.446 km² . . . . divide by the coefficient of r²

  r ≈ 4.055 km . . . . . . take the square root

The radius of the circle is about 4.06 km.

Answers

The graph of f'(x) is given, so if you find the area under the graph, that will be the value of f(x). Calculate the area of the shape under the graph from x values 0 to 4. This shape should look like a trapezoid. The area you find is actually the change in f(x) from 0 to 4. You will need to add that area to the initial value the problem gave you: f(0)=7.

Area of a trapezoid = h(b2+b2)/2
Height of the trapezoid = 2
Base 1= 2
Base 2 = 4
Area of trapezoid from [0,4] = 6

Initial value: f(0)=7

Absolute Maximum F(x): 6 + 7 = 13

Evaluate the function below for x = 4.
F(x) = x3 + 2x^2 + 1

Answers

Given parameters:

 x = 4

   Function;

           F(x) = x³ + 2x² + 1

Solution:

This is a  function related problem.

A function shows the relationship between two sets usually a domain and its range.

   For the given function;

                F(x) = x³ + 2x² + 1

                F(4)  = 4³ + 2(4)² + 1

                F(4) = 64 + 32 + 1  = 97

The value of the function is 97.
