Tan30=9/x so it will be 9((3)^1/2)
sladkih [1.3K]3 years ago

Answer:

<h2>x = 9√3</h2>

Step-by-step explanation:

Since the figure above is a right angled triangle we can use trigonometric ratios to find x

To find x we use tan

tan∅ = opposite/ adjacent

From the question

The opposite is 9

The adjacent is x

Substitute the values into the above formula

That's

\tan(30)  =  \frac{9}{x}

x \tan(30)  = 9

Divide both sides by tan 30

x =  \frac{9}{ \tan(30) }

We have the final answer as

<h3>x = 9√3</h3>

Hope this helps you

Solve for c; a/b+c=d/c
Eduardwww [97]

To solve for c, you need to get c onto one side of the equation, or make it c=__. So what I would do first is subtract a/b from both sides

a/b + c = d/c

-a/b

a/b - a/b + c = d/c - a/b

c = d/c-a/b

Show that n(n+1)(n+2) is divisible by 6<br>Solution<br>(​
vladimir2022 [97]

Proof by induction

Base case:

n=1: 1*2*3=6 is obviously divisible by six.

Assumption: For every n>1 n(n+1)(n+2) is divisible by 6.

For n+1:

(n+1)(n+2)(n+3)=

(n(n+1)(n+2)+3(n+1)(n+2))

We have assumed that n(n+1)(n+2) is divisble by 6.

We now only need to prove that 3(n+1)(n+2) is divisible by 6.

If 3(n+1)(n+2) is divisible by 6, then (n+1)(n+2) must be divisible by 2.

The "cool" part about this proof.

Since n is a natural number greater than 1 we can say the following:

If n is an odd number, then n+1 is even, then n+1 is divisible by 2 thus (n+1)(n+2) is divisible by 2,so we have proved what we wanted.

If n is an even number" then n+2 is even, then n+1 is divisible by 2 thus (n+1)(n+2) is divisible by 2,so we have proved what we wanted.

Therefore by using the method of mathematical induction we proved that for every natural number n, n(n+1)(n+2) is divisible by 6. QED.

A granite installation company schedules its services based on the installation space. It schedules 3 hours for a standard kitch
dsp73

Answer:

Part A

3 Bathroom and 3 Kitchen

Part B.

$13,500

Step-by-step explanation:

Bathroom per day = 3

Average profit of Bathroom = $1,200 per hour

Kitchen per day = (12 hours - 3 hours)/3 = 3 kitchen

Average Profit from Kitchen = $3,300 / 3 = $11,00 per hour

As the company cannot do more than 3 bathrooms which has higher per hour average profit, the remaining 9 hours will be utilized  for Kitchen Installation.

Part A.

Company will do 3 Bathrooms and 3 Kitchens in order to maximize the profit under given condition.

Part B.

Total Earning = ($1,200 x 3 ) + ($1,100 x 9 ) = $3,600 + $9,900 = $13,500

The company will earn Average profit of $13,500.
