Caleb is correct the table doesn't have a constant rate of change so it can't be linear.
What is a nonlinear function?Any function whose graph is not a line is said to be nonlinear. It has the equation f(x) = ax + b. With the exception of form f(x) = ax + b, its equation can take any form. Any two points on the curve have the same slope. Every pair of points on the graph do not have the same slope.
The rate of change of the function is not constant for the given data so it can not be a linear function. It's an exponential function.
4/2 = 2; 8/4 = 2; 16/8 = 2.

— 3x = у
— 9x — 5y = — 48
Answers
Step-by-step explanation:
plug in -3x for y
-9x-5(-3x)= -48
-9x+15x= -48. its +15 because negative times negative is.
positive
6x= -48 (-9 +15=6) now divide both sides by 6
x= -8
now you can solve for y by plugging in -8 for x
-3(-8) =y
24= y
Explanation:
-3x = y ............................... (1)
-9x - 5y = -48 ................... (2)
From (1):
-3x = y
y = -3x
Sub (1) into (2):
-9x - 5(-3x) = -48
-9x + 15x = -48
6x = -48
x = -48/6
x = -8
Sub x = -8 into (1):
y = -3(-8)
y = + 24

The indicated side of the right-angled triangle is 6.
What is a right-angled triangle?A triangle is said to be right-angled if one of its inner angles is 90 degrees, or if any one of its angles is a right angle.
Given:
The triangle is a right-angled triangle.
So, we know,
SinФ = perpendicular / hypotenuse.
And here, perpendicular = 3 unit
And hypotenuse = x unit
Substituting the values,
Sin30° = 3/x
1/2 = 3/x
x = 6
Therefore, the value of x is 6.

Color: Red Orange Yellow Green Blue
Frequency: 16 11 9 14 10
Find the probability of spinning each color, based on the data. Explain how you calculated each probability.
Answers
Step-by-step explanation:
Probability of spinning a specific colour is the frequency of the colour divided by the total frequency.
Total frequency = 16 + 11 + 9 + 14 + 10 = 60
Hence we have the following probabilities:
P(Red) = 16/60 = 4/15P(Orange) = 11/60P(Yellow) = 9/60 = 3/20P(Green) = 14/60 = 7/30P(Blue) = 10/60 = 1/6Henry is trapped at the roof top of a burning building, which is 24 feet high.

Step-by-step explanation:
A man invests 10000 for 3 years at a certain rate of interest, compounded annually. At the
end of one year, it amounts to 11200. Calculate :
(i) the rate of interest per annum;
(ii) the interest accrued in the second year;
(ii) the amount at the end of the third year.
Answers
Step-by-step explanation:
10000, After 1 year amount = 11200 so interest after 1 year = 1200
Amount = P(1+R/100)T
11200 = 10000(1+R/100)1
R = 12%
Interest for the second year = 11200(1+12/100)1 - 11200 = 1344
after 3 years = 10000(1+12/100)3 = 14049.28
Step-by-step explanation:
(I) Principle = Rs 10000, After 1 year amount
= Rs 11200 so interest after 1 year
= Rs 1200
R = 12%
Amount = P(1+R/100)T
11200 = 10000(1+R/100)1
R = 12%——————————————————————————————————————
(Ii)Interest for second year = 11200(1+12/100)1 - 11200 = Rs 1344
(iii)Amount after 3 year = 10000(1+12/100)3 = Rs 14049.28
