Answer:

b and c

Step-by-step explanation:

They both follow the formula of a linear function: y = mx + c, where m is the gradient and c is the y-intercept.

When you rearrange:

a. y = 60/x (this is a reciprocal function)

b. y = x - 1 (says that this linear function has a gradient of 1 and cuts the y-intercept at (0,-1))

c. y = 3x/2 -5/2 (says that this linear function has a gradient of 3/2 and cuts the y-intercept at (0, 5/2))

DiKsa [7]
Vcone=1/3(hpir^2)
Vsphere=(4/3)pir^3

evaluate
vcone=1/3(1pi1^2)=pi/3
vsphere=4/3pi1^3=4pi/3


pi/3 times what=4pi/3
times both sides by 3
pi times what=4pi
divide both sides by pi
1 times what=4
what=4

lesantik [10]

Answer:

A. y = 3x/4

Step-by-step explanation:

 a proportional relationship between x and y is a straight line passing through the origin (0, 0).

The equation must be in the form y = kx.

y = 3x/4

y = 3/4x

Molly Invests $8,600 into her son's college fund, which earns 3% annual interest
8_murik_8 [283]

Answer:

n= 13.8 years

Step-by-step explanation:

<u>First, we need to determine the daily interest rate:</u>

Daily interest rate= 0.03 / 365

Daily interest rate= 0.000082

<u>Now, using the following formula we can determine the number of days and years:</u>

n= ln(FV/PV) / ln(1+i)  

n= ln(13,000 / 8,600) / ln(1.000082)

n= 5,039 days

<u>In years:</u>

n= 5,039/365

n= 13.8 years
