Answer:

Just realized I gave you the wrong answer. Here's the right one below:

Step-by-step explanation:

(44 1/2)/(1 1/4)

(89/2)/(5/4)

(89/2)(4/5)

178/5

35 3/5 mpg

Sorry about that! :)

There are a total of 84 green cars, 35 blue cars, and 42 red cars parked in the parking lot. How many cars are parked in the par

Cloud [144]

Ok so you just have to add all of the quantities together so 84+35=119 and then 119+42=161 so there are 161 cars in the parking lot. Hope this helps

F(n+1)=f(n)-5. If f(1)=100, what is f(6)

PilotLPTM [1.2K]

Answer:

Step-by-step explanation:

Given:

f(1) = 100

f(n+1) = f(n) - 5

Solve for:

f(6)

Solution:

f(1) = 100

f(2) = f(1) - 5 = 100 - 5 = 100 - 1 x 5 = f(1) - 1 x 5

f(3) = f(2) - 5 = 100 - 5 - 5 = 100 - 2 x 5 = f(1) - 2 x 5

...

f(n) = f(n - 1) - 5 = 100 - (n-1) x 5 = f(1) - (n-1) x 5

=> f(6) = f(1) - (6-1) x 5 = 100 - 5 x 5 = 100 - 25 = 75

Hope this helps!

In each of problems 5 through 11, find the general solution of the given differential equation

Brrunno [24]

The complete question is

"Find the general solution of the given differential equation

y''-y=0, y1(t)=e^t , y2(t)=cosht

The function $y(t)=e^t$ is the solution of the given differential equation.

The function y(t)=cosht is the solution of given differential equation.

<h3>What is a function?</h3>

The function is a type of relation, or rule, that maps one input to specific single output.

Given;

$y_1(t) = e^t$

Given differential equations are,

y''-y = 0

So that,

$y' (t) = e^t, y'' (t) = e^t$

Substitute values in the given differential equation.

$e^t -e^t=0$

Therefore, the function $y(t)=e^t$ is the solution of the given differential equation.

Another function;

$y(t)=cosht$

So that,

$y"(t)=sinht\\\\y"(t)=cosht$

Hence, function y(t)=cosht is solution of given differential equation.
