A certain species of fish has been declining in population by 7% per year. That means it's rate of decay is 0.93. The population

at time zero is 500,000. What is the initial population?

We know that a rate of decay for a certain species of fish is 0.93. It means that it has been declining in population 7% per year. But we also know that the population at time zero ( at start ) is 500,000.The initial population = the population at time zero.Answer: The initial population is 500,000.

Solve the system of equations<br><br> a+s=560<br><br> 8a+3s=2905
Rasek [7]

Answer:

a=245 s=315

Step: Solve a+s=560 for a:

a+s=560

a+s=560(Add -s to both sides)

a=−s+560

Step: Substitute −s+560 for a in 8a+3s=2905:

8a+3s=2905

8(−s+560)+3s=2905

−5s+4480=2905(Simplify both sides of the equation)

−5s+4480=2905(Add -4480 to both sides)

−5s=−1575

−5s=−1575(Divide both sides by -5)

s=315

Step: Substitute 315 for s in a=−s+560:

a=−s+560

a=−315+560

a=245

What is the thirty-second term of the arithmetic sequence -12, -7, -2, 3, ... ? Show your work.
anzhelika [568]

The thirty-second term is 143

Further explanation:

As it is already given that the given sequence is an arithmetic sequence

We have to find the common difference first

So,

a_1=-12\\a_2=-7\\a_3=-2\\a_4=3

d=a_2-a_1=-7-(-12)=-7+12=5\\a_3-a_2=-2-(-7)=-2+7=5

The common difference is 5.

And first term is -12

The explicit formula for arithmetic sequence is:

a_n=a_1+(n-1)d\\Here,\\a_n\ is\ nth\ term\\a_1\ is\ first\ term\\d\ is\ common\ difference

Putting the values in the formula

a_n=-12+(n-1)(5)\\a_n=-12+5n-5\\a_n=-17+5n

Putting n=32 in explicit formula

a_{32}=-17+5(32)\\=-17+160\\=143

The thirty-second term is 143

Sergio [31]

Answer:

Step-by-step explanation:

1.8C + 32 would be ur expression

when C = 25

F = 1.8C + 32

F = 1.8(25) + 32

F = 45 + 32

F = 77 degrees <====
