Answer:

B) A herd of lions whose numbers triple every decade.

Situations that can be modeled by exponential functions:

A situation can be modeled by exponential functions when the change is a multiplication or a division, not a sum or subtractions.

In this question:

In option A, C and D the measures are a sum or subtractions, as the rate of change is always the same. So it rests option B as the answer, as tripling is multiplying by 3.

A bowl in the shape of a hemisphere has a volume of 144π cubic centimeters. What is the radius of the bowl?

Alla [95]

Answer:

6 = r

Step-by-step explanation:

V = $\frac{2}{3}$ πr³ Use this equation to find the volume of a hemisphere

144π = $\frac{2}{3}$ πr³ Divide both sides by $\frac{2}{3}$ π

216 = r³ Take the cube root of both sides

6 = r

Priya has picked 1 1/2 cups of raspberries which is enough for 3/4 of the cake how many cups does she need for the whole cake

Zina [86]

Answer:

So Priya need $2$ cups of raspberries for the whole cake.

Step-by-step explanation:

Given data;

$1\frac{1}{2}=\frac{3}{2}$ cups of raspberries which is enough for $\frac{3}{4}$ of the cake.

For making $\frac{3}{4}$ of the cake need $\frac{3}{2}$ cups of raspberries.

For making $1$ cake need $\frac{\frac{3}{2}}{\frac{3}{4}}$ cups of raspberries.

For making $1$ cake need $\frac{3}{2} \times \frac{4}{3}=2$ cups of raspberries.

∴ Priya need $2$ cups of raspberries for the whole cake.
