Q3.

The exponential growth model for fish:

F- number of fish, x- number of months, 1.02 - growth factor

Calculations:

All numbers rounded

Answer:

a) F(12) = 821(1.02)¹² = 1041

b) F(120) = 821(1.02)¹²⁰ = 8838

All numbers rounded

first:

[tex]\left(\frac{1}{4}+1\frac{1}{2}\right)\cdot \frac{1}{2} =\left(\frac{1}{4}+\frac{3}{2}\right)\cdot \frac{1}{2} =\frac{\left(\frac{1}{4}+\frac{3}{2}\right)\cdot \:1}{2} =\frac{\left(\frac{1}{4}+\frac{6}{4}\right)\cdot \:1}{2} =\frac{\frac{7}{4}\cdot \:1}{2} =\frac{\frac{7}{4}}{2} =\frac{7}{4\cdot \:2} =\frac{7}{8}[/tex]

So the first is the correct one.

Answer:

It would be 1 1/8 because 1 times 1 = 1 and the 4 times 2 would be 8 so there is 1 1/8

Step-by-step explanation:

Answer:

B

y=2x+4

Step-by-step explanation:

The y-intercept is 4, as the line passes through the y-axis only once, and at (0,4)

The format of a linear graph is y=mx+b where m is the slope and b is the y-intercept.

You can already tell that B is the only one with the y-intercept of 4.

The slope can be calculated quite easily, as we will start from (0,4) and make our way up to the next easily discernible point. The next most easily point seen is (2,8) so we will use the slope equation to find the slope. The equation is more or less like y2-y1  over x2-x1.

The y2 and x2 would be the (2,8) point because that is the second point on the line we are using. The x1 and y1 would be the first point (0,4). Now we will fill in the equation, which will look like 8-4  over 2-0  which will be 4 over 2, simplified to 4/2 and 2/1, being equal to 2.

The slope/m will be equal to 2, so the equation will look like

y=2x+4

Hope this helps!

Answer:

1/3

Step-by-step explanation:

Answer:

1/3

Step-by-step explanation: because the equation is in the format f(x)= mx+b and mx represents slope and b represents y. 2/9x is the slope so 1/3 is the y intercept (can i have brainliest)

Answer: E. 40

Step-by-step explanation:

The x-intercept of a line is when the y coordinate is equal to zero, so input zero in for y and solve for x to find the x-intercept.

1/2x + 3/5(0) = 20

1/2x = 20    

 x = 40

Answer:

x=9/23 and y=18/23

Step-by-step explanation:

Substitute 2 x for y in 25x−y=9

25x−y=9

25x−2x=9

23x=9

23x/23=9/23

x=9/23

substitute 9/23 for x in y=2x

y=2x

y=2(9/23)

y=18/23

x= 9/23 and y=18/23

Answer:

(iii) C = {0}.

iv) The set of all triangles having four sides is a NULL ser

Step-by-step explanation:

Complete question

Identify the following sets as null set or singleton set.

(i) A = {x : x ∈N, 1 < x < 2}

(ii) B = The set of all even natural numbers which are not divisible by 2

(iii) C = {0}.

(iv) D = The set of all triangles having four sides.

A null set is a set that contains no element while a singleton set is. a set that has only one element

The set C ={0} has just one element which is zero. This shows that the set is a singleton set

Also a triangle only has 3sides. No triangle can have 4sides. Hence the set of all triangles having four sides is a NULL SET

Answer:

126

Step-by-step explanation:

This is a tricky question!

So we can quickly find the area of the whole circle through πr². That would be around 144π (remember, we are solving in terms of π, so we dont use 3.14)

Then, the circles. Through πr², we can find that the area of one circle is 9π. And since there are two circles, we can add these together to become 18π.

Now we subtract 144π from 18π to find the shaded area. 126π, and since we are doing this in the terms of π, we don't need to include that.

Answer:

Look down below!

Step-by-step explanation:

Alright, so let's start solving this

1. First we are going to be placing the x one one side and the constants (or the regular numbers) on the other side.

How to do that?

Well, we can take -3x and 20 to their other sides.

The reason for this is that we don't want to have the value with x as a negative

So we do

-3x-4 = 20

+3x -20 -20+3x

You may not understand what was about but all I did was just added 3x to both sides and subtracted 20 to both sides to make the new equation

-24 = 3x or 3x = -24

Now we can see that the x has a number it is being multiplied with so to get rid of the number we divide everything by 3

So

3x/3 = -24/3

Which results in x = -8 and voila, there is your answer!
