A car travels at a constant speed of 65 miles per hour. The distance the car travels in Miles d, which is a function of time, t.

This relation can br expressed in the function equation, d(t) = 65t. This function expresses the distance of travel in terms of the time traveled. Find the inverse function by expressing the time of travel in terms of the distance traveled. Call this function t(d). ​

Answer:

t(d) = ᵈ/₆₅

Step-by-step explanation:

When you hear "inverse", it means everything changes places, or is the inverse of the other. So, as a function of t(d), originally it was 65t, so the inverse of that as a function of t(d) is ᵈ/₆₅.

I am joyous to assist you anytime.

Answer:

  t(d) = d/65

Step-by-step explanation:

To solve for t, divide by its coefficient:

  d = 65t

  d/65 = 65t/65 . . divide* by 65

  d/65 = t . . . . . . . simplify

Then you can write it in function form if you like:

  t(d) = d/65

_____

* Of course, the rules of equality say you must divide <em>both sides</em> of the equation by the same number.

The glee club has $90 to spend on pens and pencils. Each pen costs $0.75 and each pencil costs $0.15. Let x represent the number
brilliants [131]

Answer:

part A; B and Part B;  pencils

Step-by-step explanation:

you want to find out how many pens and pencils you cn buy with that 90$ so you want to do

.75y+.15x=90

pens=50

pencils=50

but you want to add .75+.15 which = .90

then you divide 90/.90

and that equals 100

then split it up and each gets 50

Answer:

$15.25

Step-by-step explanation:

$7.50+$4.85+$12.25 +$9.00 +$8.15 = $41.75

$28.50*2 = $57.00

So, he needs $57.00- $41.75 = $15.25 more

Unless otherwise specified, the domain of a function f is assumed to be the set of all real numbers x for which f(x) is a real n
e-lub [12.9K]

Answer:

See Below

Step-by-step explanation:

The function is a piecewise function defined as:

N(t)=\left \{ {{25t+150} \ 0 \leq t \leq 6 \atop {\frac{200+80t}{2+0.05t} \ t \geq 8}} \right.

a)

We need to find the limit of the function as t goes to infinity. This means what is the max value of fish in the pond given times goes to infinity (on an on).

We will take the 2nd part of the equation since t falls into that range, t is infinity, which is definitely greater than 8.

\lim_{t \to \infty} \frac{200+80t}{2+0.05t} \\\lim_{n \to \infty} \frac{80t}{0.05t}\\ \lim_{n \to \infty} \frac{80}{0.05} =1600

This means the maximum number of fish at this pond is 1600, no matter how long it goes on.

b)

A function is continuous at a point if we have the limit and the functional value at that point same.

Functional value at t = 8 is (we use 2nd part of equation):

\frac{200+80t}{2+0.05t}\\\frac{200+80(8)}{2+0.05(8)}\\=350

We do have a value and limit also goes to this as t approaches 8.

So, function is continuous at t = 8

c)

We want to find is there a "time" when the number of fishes in the pond is 250, during t from 0 to 6. We plug in 250 into N(t) and try to find t. Make sure to use the 1st part of the piece-wise function. Shown below:

N(t)=25t+150\\250=25t+150\\25t=250-150\\25t=100\\t=4

The time is 4 years when the number of fishes in the pond is 250
