A study is done on the population of a certain fish species in a lake. Suppose that the population size P(1) after years is given by the following exponential
function.
P(t) = 400(1.22)
Find the initial population size.
Does the function represent growth or decay?
O growth O decay
By what percent does the population size change each year?

Answer:

Federcio's age possible values are those that are greater than 14 i.e 15, 16, 17 and so on

Step-by-step explanation:

Let Federico's age = x

Three times the difference of Federico’s age, and 4 means:

3(x - 4)

Increased by 7:

3(x - 4) + 7

Is greater than 37:

3(x - 4) + 7 > 37

Solving the inequality:

3x - 12 + 7 > 37

3x - 5 > 37

3x > 37 + 5

3x > 42

x >42/3

x > 14

Federcio's age possible values are those that are greater than 14

Answer:

u1 = 210

u2 = 206 = u1 - 4

u3 = 202 = u2 - 4

........

un = u1 - 4(n - 1) = 214 - 4n

so the 35th term is 214 - 4.35 = 214 - 140 = 74

Answer:

z = 9

Step-by-step explanation:

7z = z + 54

7z - z = 54

6z = 54

z = 54 / 6

z = 9

Answer: 1%

Step-by-step explanation:

Question is incomplete as it lacks the details of the withdrawal fee.

We shall assume one so that we can use it for calculation so that you can understand the methods.

Assume withdrawal fee of R50.

The withdrawal amount was R5,000 and the cost to withdraw was R50.

The percentage of the withdrawal fee in relation to the total amount is:

= Withdrawal amount / Total amount * 100%

= 50 / 5,000 * 100%

= 1%

Answer:

w = 2√155 ft ✅

Step-by-step explanation:

Given that:

depth (d) = 10½ ft

Volume (v) = 6,510 ft³

Find the width (w) of the hole!

If the base is a square, then

the width and the length of the base is 'equal', so the

Volume of a cuboid =

V = w²d

width = square root of the division of volume by depth

w = √(V/d)

w = √(6,510/10½)

w = √620

w = √(4×155)

w = 2√155 ft ✅

Answer:

The answer is [tex](2x+3)^2[/tex].

Step-by-step explanation:

Multiply the coefficient of the squared term and the constant. Then, find the factors that add up to 12:

[tex]4*9=36\\36:\{1*36,2*18,3*12,4*9,6*6\}\\6+6=12[/tex]

Split the middle term:

[tex]4x^2+6x+6x+9[/tex]

Factor by grouping:

[tex][4x^2+6x]+[6x+9]\\2x(2x+3)+3(2x+3)\\(2x+3)(2x+3)\\(2x+3)^2[/tex]

First Question:

Follow PEMDAS

Parentheses, Exponents, Multiplication or Division, Addition or Subtraction

3 ÷ [tex]\frac{1}{4}[/tex] × (12 + 2³)

= 3 ÷ [tex]\frac{1}{4}[/tex] × (12 + 8)

= 3 ÷ [tex]\frac{1}{4}[/tex] × (20)

= 3 × 4 × 20

= 12 × 20

= 240

Second Question:

change the mixed number into an improper fraction:

[tex]3\frac{2}{3}[/tex] = [tex]\frac{11}{3}[/tex]

= [tex]\frac{11}{3}[/tex] ÷ [tex]\frac{3}{4}[/tex]

= [tex]\frac{11}{3}[/tex] × [tex]\frac{4}{3}[/tex]

= [tex]\frac{44}{3}[/tex]

rounded to WHOLE number: 14 containers

Answer:

one solution

Step-by-step explanation:

here, we want to select the correct option

From the system, we have two values of y

Equating the y-values

3x + 2 = -2x - 1

What this mean is that there is only a particular point where this solution will work and as such, the system has one solution

answer:

true

false

true

good luck :)

hopefully, this helps

have a great day !!

Answer: 24

Step-by-step explanation:

Given

Pilar made 6 quarts of orange marmalade

If each jar stores [tex]\frac{1}{4}\ \text{or}\ 0.25[/tex] quart of marmalade then

No of jars required to store marmalade is

[tex]\Rightarrow n=\dfrac{6}{\frac{1}{4}}=\dfrac{6\times 4}{1}=24\ \text{jars}[/tex]

Answer:

24

Step-by-step explanation:

Okay she got 6 quarts of orange marmalade and she pouring 1/4 quarts into a jar.

I will draw out the problem for you

1/4 + 1/4 +1/4 + 1/4 = 1 quart

1/4 + 1/4 +1/4 + 1/4 = 2 quart

1/4 + 1/4 +1/4 + 1/4 = 3 quart

1/4 + 1/4 +1/4 + 1/4 = 4 quart

1/4 + 1/4 +1/4 + 1/4 = 5 quart

1/4 + 1/4 +1/4 + 1/4 = 6 quart

and if u count all the 1/4 in the thing I just type, it will be 24
