nature and in the laboratory
x = premoult (before shedding) shell size (mm)
y = postmoult (after shedding) shell size (mm)
This bivariate data set was modelled using a linear
least

90 divided by 3 + ( 3 - 2 ) - 20.
Answers
Answer:
11
Step-by-step explanation:
first 3-2=1 the divide 90 by 3 then add the 1 the subtract that by 20 and you will get 11
The result of the expression 90 divided by 3 plus the quantity (3 minus 2) minus 20 is 11.
To evaluate the expression 90 divided by 3 + (3 - 2) - 20, we can follow the order of operations (also known as PEMDAS/BODMAS), which stands for Parentheses/Brackets, Order/Exponents, Division/Multiplication, and Addition/Subtraction:
First, let's simplify the expression within the parentheses:
3 - 2 = 1
Now we can substitute the simplified expression back into the main expression:
90 ÷ 3 + 1 - 20
Next, perform the division:
90 ÷ 3 = 30
Now we have:
30 + 1 - 20
Next, perform the addition:
30 + 1 = 31
Finally, perform the subtraction:
31 - 20 = 11
Therefore, the value of the expression 90 divided by 3 + (3 - 2) - 20 is 11.

Find all possible values of x for which these two triangles are similar.
Answers
Answer:
I see no solution.
Step-by-step explanation:
The sum of the angles of a triangle is 180°
Given
x+ x + 10 +y = 180. and
2x -50 + 50 + y = 180
y represents the angles with no value indicated.
Simplifying:
2x +y +10 = 180
2x + y = 180
This looks like a no solution system.
If I'm missing something, I hope someone else can explain it.
The two triangles are similar when two angles of the triangle are equal.
The possible value of x which the two triangles are similar is x = 60°
Reasons:
Required;
To find the values of x for which the two triangles are similar
Method:
Given that two angles of the triangle are specified, the triangles can be
similar for only one value of x.
Solution:
The two triangles are similar when we have;
x + 10° = 2·x - 50°
Which gives;
2·x - x = 50° + 10° = 60°
x = 60°
Checking gives;
x + 10° = 2·x - 50° = 70°
Two angles of the first triangle are;
70° and 60°
The third angle of the first triangle is (180° - (70° + 50°)) = 60°
The three angles of the first triangle are therefore; 70°, 60° and 50°.
Two angles of the second triangle are;
70° and 50°
The third angle of the second triangle is (180° - (70° + 50°)) = 60°
The three angles of the second triangle are therefore; 70°, 60° and 50°
Therefore, the two triangles are similar by AAA similarity.
The two triangles are similar when, x = 60°When x = 50°, we have;
x + 10° gives;
50° + 10° = 60°
∴ ∠(x + 10°) = 60°
The two angles of the first triangle are; 60° and 50°
The third angle on the second triangle is 180° - (60° + 50°) = 70°
On the second triangle, we have;
2·x - 50° gives;
2 × 50° - 50° = 50°
∴∠(2·x - 50°) = 50°
Therefore, the two angles of the second triangle are; 50° and 50°
The third angle on the second triangle is 180° - (50° + 50°) = 80°
Therefore, the two triangles are not similar when x = 50°
Similarly, the two triangles are not similar when x + 10° = 50°
Therefore;
The possible value of x which the two triangles are similar is x = 60°

If you think of it as there being 2 squares instead of 1, you can think well since the whole one side of the rectangle is 8cm and the half side is 4 then that must mean that the other square that you just divided up must be 3 by 4 so then you can multiply those and get 12 and you do the same for the other one which would be 4 by 5 and when you multiply those you will get 20 and when added you get 32.

c) points: (0, 600), (1, 400); equation: y = 100 +500·(0.6^x)
Step-by-step explanation:
c) It is convenient to choose points that are on the grid intersections. Two such points are ...
(0, 600) and (1, 400)
From part (a), you know that the horizontal asymptote is 100, so this is the value that is added to the exponential function. That is, the exponential term of the function decays from 600-100 = 500 at x=0 to 400 -100 = 300 at x=1. The "growth factor" is then 300/500 = 3/5 = 0.6.
The exponential equation is then ....
y = (horizontal asymptote) + (initial exponential term)(growth factor)^x
Using the numbers we just developed, this is ...
y = 100 + 500(0.6^x)

Determine net change and average change between the given values of the variables
Answers
f(x) = 1-3x, x = 4 , x = 4+h
(a) find the net change of f(x):
f1= f(x=4) = 1-3(4) = 1 - 12 = -11
f2= f(x=4+h) = 1-3(4+h) = 1-12 + 3h = -11 - 3h
Net change = f2 - f1 = -11 -3h - -11 = -3h
(b) average rate of change = slope = (f2 - f1)/(x2-x1) = -3h/((4+h)-4 =-3
