Given a set of data, what steps would you take to identify whether the data showed linear or exponential growth?
Answer:
See explanation
Step-by-step explanation:
The first thing to do when given a data set is to ensure that the x-values are spaced in equal intervals.
The next is now to determine if the given y-values are increasing by the same amount(a common difference) or by the same ratio(a common ratio).
The data set is linear if the y-values increase by a common difference and the data set is exponential if the y-values increase by a ratio or factor.
Answer:
Which of the following steps did you include? Check all of the boxes that apply.
Make sure that the x-values are spaced apart in equal intervals.
Determine whether the y-values increase by the same amount or by the same ratio.
Decide that the data is linear because the y-values increase by a common difference.
Decide that the data is exponential because the y-values increase by a ratio or factor.

A phone company offers two monthly plans. Plan A costs $8 plus an additional $0.09 for each minute of calls. plan B cost $16 plus an additional $0.07 for each minute of calls.
a. For what amount of calling do the two plans cost the same? minutes
b. What is the cost when the two plans cost the same? $
Answer: 72
Plan A = 30 +0.15x
Plan B = 16 +0.20x
30+0.15x = 16+0.20x
subtract 16 from each side
14 +0.15x = 0.20x
subtract 0.15x from each side
14=0.05x
x = 14/0.05 = 280 minutes
280*0.15 = 42 +30 = $72
280 * 0.20 = 56 +16 = 72
280 minutes and cost $72 each

A shirt is sold for Rs 285, there is a loss of 5%. At what price should the shirt be sold so as to have a profit of 15%?
Answer:
345 !
Step-by-step explanation:
SP = 285
loss = 5 %
CP= ( SP * 100 ) / ( 100 - percentage loss)
CP= 28500 / 95 = 300
~~~~~~~~~~~~~~```
CP= 300
profit = 15%
SP = [(100 + Profit %) / 100]*CP.
SP= 100 + 15 / 100 x 300
= 115 / 100 x 300
= 345

What is the best prediction of the time required for
the oil spill to reach a diameter of 10 km?
A 147 days
B200 days
205 days
D233 days
Answer:
Step-by-step explanation:
It's 205
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be 147 days. Then the correct option is A.
What is a quadratic equation?The quadratic equation is given as ax² + bx + c = y. Then the degree of the equation will be 2.
The table shows the connection between the width in kilometers of an oil slick and the time in days. A capability can be utilized to show this relationship.
The equation at (2.4, 1) will be given as,
2.4 = a (1)² + b (1) + c
2.4 = a + b + c ...1
The equation at (9.4, 2) will be given as,
9.4= a (2)² + b (2) + c
9.4 = 4a + 2b + c ...2
The equation at (21.1, 3) will be given as,
21.1 = a (3)² + b (3) + c
21.1 = 9a + 3b + c ...
Solve equations 1, 2, and 3 with the calculator, then we have
a = 2.35, b = -0.05, c = 0.1
Then the equation is given as,
y = 2.35x² - 0.05x + 0.1
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be
y = 2.35(10)² - 0.05(10) + 0.1
y = 235 - 0.5 + 0.1
y = 235.5
The value of y is nearer to the value of 233. Then the value of y will be 233 days.
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be 233 days. Then the correct option is D.

{–1.2, 0, 4}
A.
{–8, –2, 18}
B.
{–4, 2, 22}
C.
{0.16, 0.4, 1.2}
Answer:
A. {–8, –2, 18}
Step-by-step explanation:
y = 5x − 2
x = −1.2 ----> y = 5(−1.2) − 2 = −6 − 2 = −8
x = 0 -----> y = 5(0) − 2 = 0 − 2 = −2
x = 4 -----> y = 5(4) − 2 = 20 − 2 = 18
9 -4n+ 3n = 8n + 3 -3
im helping a friend so please make it right
Answer:
n = 1
Step-by-step explanation:
This equation is just basic alegebra. First, combine like terms to get
9 - n = 8n. (Because 3 - 3 = 0, and -4n + 3n = -n.) Now the equation is much simpiler; add n to both sides to get 9 = 9n. Divide 9 by both sides to get that n = 1.
You can check your answer by plugging 1 in for n.
9 - 4(1) + 3(1) = 8(1) + 3 - 3
9 - 4 + 3 = 8 + 3 - 3
5 + 3 = 11 - 3
8 = 8
Therefore, n is proven to equal 1.
Hope this is helpful :)
I need help. i’m failing geometry
Answer:
x = 1 and y = 6
Step-by-step explanation:
so the opposite sides are equal to each other, therefore
4x + 7 = 12x - 1
and y + 1 = 3y - 11
so for the xs
start by adding 1 to each side
4x + 8 = 12x
subtract 4x from both sides
8=8x
divide by 8
x=1
for the ys
subtract one from each side
y= 3y -12
subract 3y from each side
-2y=-12
divide by -2
y=6
