For this case we have the following functions:

f (x) = 18x ^3-7x^2 + 5x-3\\g (x) = - 9x ^ 2-2

We must find (\frac {f} {g}) (x). By definition we have to:

(\frac {f} {g}) (x) = \frac {f (x)} {g (x)}

So:

(\frac {f} {g}) (x) = \frac {18x ^ 3-7x ^ 2 + 5x-3} {- 9x ^ 2-2}

Where the denominator must be 0stint, so that the function is defined.

That is to say:

-9x ^ 2-2 other than 0.

ANswer:

(\frac {f} {g}) (x) = \frac {18x ^ 3-7x ^ 2 + 5x-3} {- 9x ^ 2-2}

With-9x ^ 2-2 other than 0

Answer:

Step-by-step explanation: To find the function (f/g)(x) first we need to establish the limits as follows:

(f/g)(x)= \frac{18x3-7x2+5x-3}{-9x2-2}, ∀ x / -9x2-2≠0

-9x2-2=0  → 9x2=-2 → x2=-\frac{9}{2} → x=±√(9/2).

As we can see, the range of this function is ∀ x / x≠±√(9/2).

Becouse in those values, the function does´t have solution.

Need help I got 23,294 as the answer but it’s not an option please explain how you got the answer.
OLEGan [10]

Answer:

A

Step-by-step explanation:

Calculation seems correct to me, with d the distance and h the height of the plane, and i got the same value. Closest value is A tho, so i'd stick with it.

If you want to be pedantic about it, you can always divide the heigth by each value, and get the inverse tangent of each value. With A you get 17.995 which seems the best value you get

In 2010, the world's largest pumpkin weighed 1,810 kilograms. An average-sized pumpkin weighs 5,000 grams.
jekas [21]

Answer:

1,805 kg.

Step-by-step explanation:

We have been given that in 2010, the world's largest pumpkin weighed 1,810 kilograms. An average-sized pumpkin weighs 5,000 grams. We are asked to find the how much the world's largest pumpkin weighs than an average pumpkin.

First of all, we will convert the weight of average pumpkin in kilograms by dividing 5,000 by 1000 as 1 kg equals 1,000 gm.

\text{The weight of average pumpkin}=\frac{5000\text{ gm}}{\frac{\text{1000 gm}}{\text{ 1 kg}}}

\text{The weight of average pumpkin}=5000\text{ gm}\times \frac{\text{ 1 kg}}{\text{1000 gm}}

\text{The weight of average pumpkin}=5\text{ kg}

Now, we will subtract the weight of average pumpkin from world's largest pumpkin's weight.

1,810\text{ kilograms}-5\text{ kilograms}=1,805\text{ kilograms}

Therefore, the 2010 world-record pumpkin weighs 1,805 kilograms more than an average-sized pumpkin.

ON A TIME LIMIT PLS HELP!!!! thank youu
Slav-nsk [51]

Answer:

RQS=110

TQS=70

Step-by-step explanation:

(12x+2)+(7x+7)=180

The two equations added together give us a straight line which is angle 180

19x + 9 = 180

19x = 171

We solve for x

x = 9

Now that we have x we plus in to each equation

RQS= (12(9)+2)

= 110

TQS=(7(9)+7)

=70
