The expression 5(2)' gives the number of leaves in a plant as a function of the number of weeks since it
was planted.
Exponentia
What does 2 represent in this expression?
A: the plant was planted 2 weeks ago
B: there were initially 2 leaves in the plant
C: the number of leaves is multiplied by 2 each week

C: the number of leaves is multiplied by 2 each week

Step-by-step explanation:

The right expression should be 5(2) ^ t =

where t represent the number weeks after it planted.

If we put 0 to the time(t) we will know how many leaves initially are. The calculation will be:

= =5

This show that coefficient 5 determine how much the leaves initially are.

Let see how the number going for different value of t. If its 1 week after plant, the leaf will become:

= = 10

Then the number of leaves 2 weeks after planted will be:

= = 20

The number keeps double every week since coefficient 2 represents the ratio of the growth of the function and the ratio determines how much leaves multiplied each week.

So, the answer will be C.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
