Answer:
Step-by-step explanation:
Area of semi-circle is [tex]\frac{\pi r^2}{2}[/tex] ≈ [tex]\frac{22}{7}[/tex] × 4² ÷ 2 ≈ 25 cm²
Area of square is 8² = 64 cm²
Total area is 25 + 64 = 89 cm²

Which of the following best represents a linear proportional relationship?
A linear proportional relationship is shown by y = 3x - 7.
What is a linear relationship?We know that when we talk about a linear relationship, we mean the kind of relationship that would obey the equation of the straight line and the equation of the straight line would be y = mx + c
We have to look at the representations and see the one that actually fits into the model that have been shown above and when we look at it we can see that the y = 3x - 7.
This follows the pattern of the equation of the straight line.

The best representation of a linear proportional relationship is the table of values
How to determine the best linear proportional relationship?From the question, we have the following parameters that can be used in our computation:
The list of options
As a general rule, the equation of a linear proportional relationship is represented as
y = kx
Where k is the constant of proportion
This means that the given equations are not proportional relationship because they do not have the form y = kx
i.e. y = 3x - 7 and y = 8x + 25 do not have the form y = kx
Also, the equation y = kx implies that the graph passes through the origin
So, the given graph is not
The equation of the table is represented as
y = Y/X * x
So, we have
y = 2/24 * x
This gives
y = x/12
The equation of the table is of the form y = kx
Hence, the solution is the table of values

How do you do this question?
Step-by-step explanation:
(a) dP/dt = kP (1 − P/L)
L is the carrying capacity (20 billion = 20,000 million).
Since P₀ is small compared to L, we can approximate the initial rate as:
(dP/dt)₀ ≈ kP₀
Using the maximum birth rate and death rate, the initial growth rate is 40 mil/year − 20 mil/year = 20 mil/year.
20 = k (6,100)
k = 1/305
dP/dt = 1/305 P (1 − (P/20,000))
(b) P(t) = 20,000 / (1 + Ce^(-t/305))
6,100 = 20,000 / (1 + C)
C = 2.279
P(t) = 20,000 / (1 + 2.279e^(-t/305))
P(10) = 20,000 / (1 + 2.279e^(-10/305))
P(10) = 6240 million
P(10) = 6.24 billion
This is less than the actual population of 6.9 billion.
(c) P(100) = 20,000 / (1 + 2.279e^(-100/305))
P(100) = 7570 million = 7.57 billion
P(600) = 20,000 / (1 + 2.279e^(-600/305))
P(600) = 15170 million = 15.17 billion

a
a=-13, b=-13
a=-13, b=13
.
a = 13,b=-13
a = 13,- 13
Answer:
a = 13, b = 13Step-by-step explanation:
In this example predicted value is 87 and actual value is 100
Error is 100 - 87 = 13
Absolute error is same, |100 - 87| = 13
So the correct choice is the last one:
a = 13, b = 13Yesterday, a movie theater sold 274 bags of popcorn. A large bag of popcorn costs $4. A small bag of popcorn costs $1. In all, the movie theater made $523 from popcorn sales. Write and solve a system of equations to find how many bags of each size of popcorn were sold.

Answer:
The correct option is 'No Solution'.
Step-by-step explanation:
Given the system of the equations
[tex]y=\frac{1}{2}x-1[/tex]
[tex]2x-4y=12[/tex]
solving the system of the equations
[tex]\begin{bmatrix}y=\frac{1}{2}x-1\\ 2x-4y=12\end{bmatrix}[/tex]
[tex]\mathrm{Subsititute\:}y=\frac{1}{2}x-1[/tex]
[tex]\begin{bmatrix}2x-4\left(\frac{1}{2}x-1\right)=12\end{bmatrix}[/tex]
[tex]2x-4\left(\frac{1}{2}x-1\right)=12[/tex]
[tex]2x-2x+4=12[/tex]
[tex]4=12[/tex]
as
4=12 is false, therefore the system of equations has no solution.
Therefore, the correct option is 'No Solution'.

Step-by-step explanation:
5x + 6y = 20 , 8x - 6y = -46
Answer:
5x + 6y = 20_____(1)
8x - 6y = -46_____(2)
Solving simultaneously:
Eqn(1) + Eqn(2)
5x + 8x + 6y + (-6y) = 20 + (-46)
13x = -26
x = -2
substituting this into Eqn (1):
5(-2) + 6y = 20
-10 + 6y = 20
6y = 30
y = 5
hence:
x = -2,y = 5.
