A population of 120 beetles increases at an annual rate of 30%. How many beetles will there be in 16 years? Write an expression
Bas_tet [7]

Answer:

Expression: 120(1.3)^{16}

Beetles after 16 years: 7984 beetles

Step-by-step explanation:

Since the population increases 30% annually every year on the population size of that year, then we need to use a compound interest formula which would be the following

A = P (1 + r/n) (nt)

A = the future amount

P = the initial amount

r = the annual increase rate (decimal)

n = the number of times that interest/increase is compounded per unit t

t = the number of years

Using the values in the question the expression for this scenario would be the following

120(1 + (0.30 / 1))^(1*16)

120(1.3)^{16}

7984.99

THE AP CALCULUS EXAM SCORES WERE RELEASED IN JULY. THE SECONDARY MATH SPECIALIST PREPARED THE BOX PLOT SHOWN TO PRESENT THE SCOR
Ganezh [65]

Answer : option A

To find the range of scores that represents the middle 50 % of the student who took the test , we find inter quartile

Inter quartile range is the middle 50% of the given range of scores.

The difference between the upper quartile and lower quartile is the inter quartile that is middle 50%

From the diagram , we can see that

Upper quartile = 89

lower quartile = 65

So range is 65%  to 89%

1) Provide the sine, cosine, and tangent of ∠F
Naddika [18.5K]

Answer:

1. cos(F) = 2. 5/13

tan (F) = 3. 12/5

sin (F) = 1. 12/13

2. Sin (R) = 1. 60/68 = 30/34 = 15/17

cos (R) = 2. 32/68 = 16/34 = 8/17

tan (R) = 3. 60/32 = 30/16 = 15/8

Step-by-step explanation:

1 picture:

sin = Opp/Hyp

cos = adj/hyp

tan = opp/adj

cos(F) = 2. 5/13

tan (F) = 3. 12/5

sin (F) = 1. 12/13

2 Picture:

Sin (R) = 1. 60/68 = 30/34 = 15/17

cos (R) = 2. 32/68 = 16/34 = 8/17

tan (R) = 3. 60/32 = 30/16 = 15/8
