Calculate 15% of 200 first, which should give you 30.

Then add 30 to the original deer population.

200 + 30 = 230.

Answer: 23

Step-by-step explanation:

The exponential growth equation is given by :-

$y=A(1+r)^x$ , where A is the initial amount , r is the rate of growth and x is the time period.

Given : The initial population of deer :A= 200

Rate of growth: r= 15% = 0.15

Time period x=1

Now, substitute value of A, r ant x in the above eqn :-

$y=200(1+0.15)^1=230$

Hence, the population of deer in next year = 230

PLEASE HELP!<br>Calculate $40^{13} \pmod{85}.$

In this type of calculations, we decompose 13 by checking the lowest powers of the base, that is 40. for example we check 40^2, or 40^3 and compare it to 85

Notice

40*40*40=64,000

so we check how many time does 85 fit into 64,000:

64,000/85=752.94

85*753=64,005; 64000-64,005=-5

this means that

$40^{3} =-5\pmod{85}$

thus

$40^{13} =40^{3*4+1}={(40^{3})}^{4}*40=(-5)^{4}*40 \pmod{85}=\\\\625*40\pmod{85}=(7*85+30)*40\pmod{85}=30*40\pmod{85}\\\\=1200\pmod{85}=(14*85+10)\pmod{85}=10\pmod{85}$

Answer: 10 (mod85)

Remark, the set of all solutions is:

{......-75, 10, 95, .....}, that is 85k +10
