SUPER POINTS! HURRY FOR BRAINLIEST

Mathematics
1 answer:
Mumz [18]3 years ago

Answer:

A

Step-by-step explanation:

x  |  y

0    0

1     4

2    n  -> 8

3    12

I've rewritten the x-y table so it's easier to read.

Take a point: 2,8. 2 times 4 is 8.

Take another point: 3,12. 3 times 4 is 12.

Ooh, looks like we have a pattern! After testing all the points (which you should always do in case there's an outlier) each x is multiplied by 4 to get the y. The formula for this is <u>y=kx,</u> where k is the constant of proportionality. So the equation is <u>y=4x.</u> This means x and y are directly proportional.

(They would be inversely proportional if in the form y=k/x; jointly proportional if they were in the form z=kxy, and nonproportional if there was no relationship at all.)

scoundrel [369]

Answer:

The answer is "158.489"

Step-by-step explanation:

for san francisco earthquake:

\log(\frac{a_1}{T}) + B = 7.8\\\\\log(\frac{a_1}{T})+\log(10^{B}) = 7.8\\\\\log(\frac{a_1}{T} \times 10^{B})=7.8\\\\(\frac{a_1}{T} \times 10^B=10^{7.8}...............(i)

similarly , for coloumbia earthquake:

\frac{a_2}{T}\times 10^B = 10^{5.6}.................(ii)

divide equation (i) and (ii):

\frac{a_1}{a_2}=\frac{10^{7.8}}{10^{5.6}}\\\\\frac{a_1}{a_2}=10^{2.2}\approx 158.489

Rainbow [258]

Answer: the golfer would need to play golf 10 times per year.

Step-by-step explanation:

Let x represent the number of times per year that the golfer need to play golf for the two options to cost the​ same.

A social membership costs​ $1775 in annual dues. In​ addition, he would pay a ​$65 greens fee and a ​$25 golf cart fee every time he played. This means that the total cost of playing golf for x times with the social membership option is

1775 + (65 + 25)x

A golf membership costs​ $2425 in annual dues. With this​ membership, the golfer would only pay a ​$25 golf cart fee when he played. This means that the total cost of playing golf for x times with the golf membership option is

2425 + 25x

For the costs to be the same,

1775 + 65x + 25x = 2425 + 25x

65x + 25x - 25x = 2425 - 1775

65x = 650

x = 10
