Answer:

a) miles per gallon, gallons in tank

Step-by-step explanation:

All the options show functional relationship but the first one

a) miles per gallon, gallons in tank

There is no direct relationship between these parameters as miles per gallon depends on the speed and the way of driving. This won't be a function when graphed.

b) length of shadows/time of day

Shadow depends on the time of the day and its length wont repeat at different angles. This is a function.

c) temperature in F, temperature in C

This is a function as each input will have a unique output.

d) number of employees, number of hours worked

Hours of work depends on number of employees. This is a functional relationship.

Solve the equation?

stiks02 [169]

Answer:

Step-by-step explanation:

Given

p² + 2p - 8 = 0 ← in standard form

with a = 1, b = 2, c = - 8

Using the quadratic formula to solve for p

p = ( - 2 ± $\sqrt{2^2-(4(1)(-8))}$ / 2

= ( - 2 ± $\sqrt{4+32}$ / 2

= ( - 2 ± $\sqrt{36}$ ) / 2

p = $\frac{-2-6}{2}$ = $\frac{-8}{2}$ = - 4

p = $\frac{-2+6}{2}$ = $\frac{4}{2}$ = 2

Find x when y = 32, given that x varies inversely as y, and x = 132 when y = 4.

gizmo_the_mogwai [7]

Answer:

When y=32, x=16.5

Step-by-step explanation:

Find x when y = 32, given that x varies inversely as y, and x = 132 when y = 4.

We are given:

x varies inversely with y

We can write it as: $x\:\alpha \:\frac{1}{y}$

$x=\frac{k}{y}$

We have x = 132, when y=4

We can find value of k by using these values

$x=\frac{k}{y}\\132=\frac{k}{4}\\k=132*4\\k=528$

We need to find x when y=32

$x=\frac{k}{y}\\x=\frac{528}{32}\\x=16.5$

So, when y=32, x=16.5
