The hyperbola has two vertices at (-2,0) and (2,0)

We have given that the equation

[tex]\frac{x^2}{4}-\frac{y^2}{9}=1[/tex]

What is the equation of the hyperbola?

[tex]\frac{x^{2} }{a^2}+\frac{y^2}{b^2} =1[/tex]

Compare the above equation of the hyperbola with given equation

therefore a=2

vertices are (-a,0) and (a,0)

Therefore the vertices are (-2,0) and (2,0)

See the graph of the hyperbola in link given below.

Step-by-step explanation:

Let the number of smoothies sold by stand = x

And number of cones sold = y

If the selling price of each cone = $2.5

Selling price of the 'y' cones = $2.5y

Selling price of each smoothies = $4

Then sales of smoothies = $4x

If the total sales of one day = $184

Equation for this situation will be,

4x + 2.5y = 184 -------(1)

If the stand sold 6 less smoothies than the cones,

Suppose a city with population of 400,000 has been growing at a rate of ​5% per year. If this rate​ continues, find the population of this city in years.

Answers

The number of years value isn't given, we could use an hypothetical value, which can be substituted for the correct number of years given in your exercise in other to find the exact answer.

Using a t value of 10 years

Answer:

651558

Step-by-step explanation:

Given that:

Initial population, P0= 400,000

Growth rate, r = 5%

Using the relation :

P(t) = P0 * (1 + r)^t

t = number of years = 10

P(10) = 400000 * (1 + 0.05)^10

P(10) = 400000 * (1.05)^10

P(10) = 400000 * 1.628894626777

P(10) = 651557.8507

= 651558 nearest whole number.

Recall that, the t value used is hypothetical and should be replaces with te exact value given in your question.

Sin A = 5/13; tan C = 12/5

Step-by-step explanation:

Sin = opposite / hypotenuse. The opposite of A is 5, and the hypotenuse is 13, therefore Sin A = 5/13.

Tan = opposite / adjacent. The opposite of C is 12, and the adjacent is 5, so tan C = 12 / 5

Pick the diagram that models the ratio in the story.

If Fifi weighs 56 pounds, how much does Buttercup weigh?

pounds

Answers

The diagram that models the ratio in the story is diagram A.

When fifi weighs 56 pounds, Buttercup will weigh 8 pounds.

What is a ratio?

It should be noted that ratio demonstrates how many times one number can fit into another number. It contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data points.

Let buttercup be x

Let Fifi be 7x

Fifi weighs 56 pounds. This will be:

7x = 56

7x = 56

Divide

x = 56 / 7

x = 8

Buttercup is 8 pounds.
