Answer:

345 sq. ft

Step-by-step explanation:

You know that the area is the length times the width. Simply plug in values to your equation:

A = l * w

A = 23 * 15

A = 345

The area is 345 square feet.

Given:

Center of hyperbola is at (h,k).

To find:

The standard forms of a hyperbola.

Solution:

We know that, standard forms of a hyperbola are

1. For Horizontal hyperbola:

\dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1

2. For Vertical hyperbola:

\dfrac{(y-k)^2}{a^2}-\dfrac{(x-h)^2}{b^2}=1

where, (h,k) is center of the hyperbola.

Therefore, the correct option is B.

A television manufacturer decides to increase its production by 25% per month to meet increasing customer demand. The company cu
Inessa [10]

Answer:

The last graph

Step-by-step explanation:

The problem presented here is similar to a compound interest problem since we have an initial value, a growth constant and the aspect of time.

We can consider the number of television sets currently produced by the company to be our Principal amount;

P = 2000

The rate of increase in production per month can be considered as our interest rate earned;

r = 25% = 0.25

The total number of television sets y will be our Accumulated amount;

A = y

The duration x becomes our time n.

The compound interest formula is given as;

A=P(1+r)^{n}

We simply substitute the given information into the formula;

y=2000(1.25)^{x}

This is an exponential growth function since the base of the exponent x is greater than 1.

A graph of the function will be an exponential curve passing through ( 0, 2000) since 2000 is our initial value
