Answer:
Second table (B)
Input: 0, 1, 2
Output: -3, 1, 5
Explanation:
Given the 2D linear equation y = 4x - 3,
y must represent the output because it is the dependent variable, so x must represent the input because it is a independent variable.
The circumference of a circle is 9 m.
What is the area of the circle?
4.5 m2
18 m2
20.25 m2
81 m2
Answer:
[tex]20.25\pi \: {m}^{2} [/tex]
Step-by-step explanation:
[tex]Circumference = 2\pi r = 9\pi \Rightarrow r = 4.5 \\ Area = {r}^{2}\pi = {4.5}^{2} \pi = 20.25\pi[/tex]

does anyone know how to solve this using the sine rule?
Answer:
Step-by-step explanation:
According to sine law of trigonometric functions,
sin(α)/a =sin(β)/b
hence using this
sin(18)/y = sin(x)/2y
sin(x)=2*sin(18)
sin(x)=2*0.309
sin(x)= 0.618
x=sin-1(0.618) ( sin-1 is sine inverse)
x=38.17 °

Melissa has $100 in the bank. She plans to deposit $40 per week until she reaches $500. What is the rate of change? Explain what the rate of change means in the context of the problem. *
Answer:
$40 per week
Step-by-step explanation:
Step one:
Given data
the initial amount is = $100
the total amount= $500
let the number of weeks be x
Step two:
The expression for the scenario is
[tex]500= 100+40x-------1[/tex]
From the expression above, the rate of the change is $40 per week.
this means that in every week the account will be increased by $40
The temperature in a town is 34.1°F during the day and -8.6°F at night. Find the difference in the temperatures.
Answer:
the difference is 25.5
Step-by-step explanation:
34.1 - 8.6 = 25.5
[tex]42.7^{\circ}F[/tex]
Subtract the number with the smallest value from the number with the biggest value to determine the difference between two numbers.
Temperature in a town during the day [tex]=34.1^{\circ}F[/tex]
Temperature in a town during the night [tex]=-8.6^{\circ}F[/tex]
Therefore,
Difference in temperatures [tex]=34.1-(-8.6)[/tex]
[tex]=42.7^{\circ}F[/tex]

A school has 320 girls and 250 boys the probability of a girl being left handed is 0.2 the probability of a boy being left handed is 0.1 estimate the amount of left handed people there are in the school
320 girls & 250 boys
0.2 probability 0.1 probability
320 x 0.2 = 64
250 x 0.1 = 25
64 + 25 = 89
There are approximately 89 students in the school that are left-handed.
Answer
89% of the people are left handed
Step-by-Step Explanation
To find this you have to first do 320 x 0.2
320 x 0.2= 64
To find it for boys you have to do 250 x 0.1.
250 x 0.1= 25
SO, the answer is 89%. 64% of girls and 25% of boys

Dione is designing a water fountain for the lobby of a new hospital. She knows that the fountain will have a circular pool with water projected upward at a constant rate from the center of the pool. She needs to determine the maximum height, so she uses a linear model to represent the situation.
Answer:
Diane did not choose a good model. Because the water is a projectile with a maximum height, she should use a quadratic model
Step-by-step explanation:
Here, we want to choose the correct option
As we are having a circular projection, we should be looking at having a parabolic representation i.e a model that looks like a parabola
So the correct answer in this case is that;
Diane did not choose a good model. Because the water is a projectile with a maximum height, she should use a quadratic model

Is x = 6 a solution to the equation 5(x – 3) = x + 13?
Answer:
x=6 is not a solution
Step-by-step explanation:
We can substitute 6 as x to find out:
5(6-3)=6+13
first, because of PEMDAS we'll do 6-3
5(3)=6+13
multiply 5 by 3 and add 6 and 13
15=19
Since the statement is not true, that means that x=6 is not a solution

Answer:
3 , 11, 25, 45
Diff 8 14 20
Diff 6 6
The second differences are the same. The sequence is quadratic and will contain an n^2 term. The coefficient of n^2 is always half of the second difference. In this example, the second difference is 6. Half of 6 is 3 so the coefficient of n^2 is 3
therefore 3n^2
3 11 25 45
3n^2 3 12 27 48
Remainder 0 -1 -2 -3
Difference -1 -1 -1
linear sequence with nth term -n+1
so nth term of quadratic sequence in 3n^2-n+1

x=14/7
x=2
2 is the right answer.x + 80 = 180 - (64 + 36)
x + 80 = 180 - 100
x + 80 = 80
x = 0
0 is the right answer.
