Answer:

About 7.84 years before the deer population is 400

Step-by-step explanation:

So first we write our equation

125(1.16)^x = 400

Then we divide all sides by 125

1.16^x=3.2

x log 1.16 = log 3.2

06445798922x=0.50514997832

x= 7.83688700862

7.83688700862 years to go!

Complete the blank with either ∈ or ∉ so that the resulting statement is true. −2​__{−6,−3,−5,−1}
Misha Larkins [42]

Answer:

−2​ ∉ {−6,−3,−5,−1}

Step-by-step explanation:

Given

Set = {−6,−3,−5,−1}

Element = -2

Required

The interpretation of the question is to state if -2 is an element of the given set or not

The first thing to do is to check through the set to count the number of occurrence of -2

Looking through Set = {−6,−3,−5,−1}, we have that the occurrence of -2 is 0

This implies that -2 is not an element of the given set and this is represented by the symbol ∉

Hence:

−2​ ∉ {−6,−3,−5,−1}

Please help with the answer below
kenny6666 [7]

Answer:

f(x) =  \frac{x + 7}{6 - x}  \\  \frac{3}{2}  =  \frac{x + 7}{6 - x}  \\ 3(6 - x) = 2(x + 7) \\ 18 - 3x = 2x + 14 \\  - 3x - 2x = 14 - 18 \\  - 5x =  - 4 \\  \frac{ - 5x}{ - 5}  =   \frac{ - 4}{ - 5}  \\ x =  \frac{4}{5}
