An exponential function has a starting value of 13 and a growth rate of 0.78%. Write an equation to model the situation.
Elina [12.6K]

Answer:

The equation that models the situation is A(t) = 13(1.0078)^t

Step-by-step explanation:

Exponential equation:

An exponential equation has the following format:

A(t) = A(0)(1+r)^t

In which A(0) is the starting value and r is the growth rate, as a decimal.

Starting value of 13 and a growth rate of 0.78%.

This means that A(0) = 13, r = 0.0078

Write an equation to model the situation.

A(t) = A(0)(1+r)^t

A(t) = 13(1+0.0078)^t

A(t) = 13(1.0078)^t

The equation that models the situation is A(t) = 13(1.0078)^t

Yuri [45]

Question:

A cafeteria offers oranges, apples, or bananas as its fruit option. It offers peas, green beans, or carrots as the vegetable option. Find the number of fruit and vegetable options. If the fruit and the vegetable are chosen at random. what is the probability of getting an orange and carrots? Is it likely or unlikely that a customer would get an orange and carrots?

Answer:

The probability of getting an orange and carrots is \frac{1}{9}

Step-by-step explanation:

The fruits offered in cafeteria = oranges, apples, or bananas.

The vegetables offered in cafeteria  = peas, green beans, or carrots.

There are 3 fruits and 3 vegetables . Therefore the total possible number of  outcomes is  = 3 \cdot 3 =  9

Now the probability of getting an orange and carrots = \frac{1}{9}

The possibility is very unlikely to happen
