Given that h varies inversely with respect to g, and that h= -24 when g= 3, write an
equation that describes the relationship between h and g. Then find h when g=-1,

Answers

Answer:

h = 72

Step-by-step explanation:

Given that h varies inversely with g then the equation relating them is

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

To find k use the condition h = - 24 when g = 3 , then

- 24 = [tex]\frac{k}{3}[/tex] ( multiply both sides by 3 )

- 72 = k

h = - [tex]\frac{72}{g}[/tex] ← equation of variation

When g = - 1 , then

h = - [tex]\frac{72}{-1}[/tex] = 72

how do you know of an exponential fuction is reflected across the x-axis?​

Answers

Answer:

Step-by-step explanation:

A reflection over the x-axis changes all the y-values. The reflection is modeled as -f(x)

For example:

[tex]\sqrt{x}[/tex] would look like --[tex]\sqrt{x}[/tex] .

If the negative sign is outside of the bracket ( what it's called sorry), then it is a reflection over the x-axis

However if the negative sign was inside the bracket: [tex]\sqrt{-x}[/tex] then this would be a reflection over the y axis.

Hope this helps!

A unicycle wheel has a diameter of 30 inches. How many inches will the unicycle travel in 5 revolutions? Use π = 3.14 and round your answer to the nearest hundredth of an inch.

Answers

Answer:

471.3inches

Step-by-step explanation:

Given data

Diameter= 30in

Radius= D/2= 30/2= 15in

The circumference is the same as the distance covered in one revolution

C= 2πr

Hence the distance  covered in 5 revolutions is

C= 2*5*πr

Substitute

C=10*3.142*15

C= 471.3inches

Gary goes to the grocery store to buy hot dogs and hamburgers for a cookout. He buys a total of 8 packages for a total of $28.52. A package of hot dogs costs $2.29 and a package of hamburgers costs $5.69.

Answers

Answer:

3 hamburger packs

5 hot dog packs

Step-by-step explanation:

The system of equations that corresponds to the situation is:

1. x + y = 8

2. 2.29x + 5.69y = 28.52

Let's use variables to represent the unknowns in the problem.

Let:

x = number of packages of hot dogs purchased

y = number of packages of hamburgers purchased

We are given the following information:

1. Gary buys a total of 8 packages: x + y = 8

2. The total cost of the packages is $28.52: 2.29x + 5.69y = 28.52

So, the system of equations that corresponds to the situation is:

1. x + y = 8

2. 2.29x + 5.69y = 28.52
