Answer:

c) All integers from 10 to 50, inclusive

Step-by-step explanation:

Rauls is selling coupon books.

He started with 50 coupon books and has already won a prize for selling at least 10 coupon books. It means He has a maximum value of 50 coupons and he already sold 10 coupons.He can sell from 10 coupons to 50 coupon books.

The total amount of money Raul will make from selling x coupon books as a function is

f(x) = 20x

The domain of this function is all Real numbers. However, we need a practical domain.Coupon books are integer numbers, 1, 2, 3 we will not have a half book. So, Coupon right now can vary from 10 coupon books to 50 coupon books. It means x can vary from 10 to 50, only integer values and inclusive 10 and 50.

Finally, the answer is C) all integers from 10 to 50, inclusive.

Suppose xy=−4 and dy/dt=−3. Find dx/dt when x=−1.

user100 [1]

When x=-1: $\quad (-1)y=-4\qquad\to\qquad y=4\)$

Ok that gives us a little more information.
If we implicitly differentiate with respect to t, from the very start, then we can apply our product rule, ya?

$x'y+xy'=0$

The right side is zero, derivative of a constant is zero.
Where x' is dx/dt and y' is dy/dt.

From here, plug in all the stuff you know:
y' = -3
x = -1
y = 4

and solve for x'.

Hope that helps!

Find the value of x. Round your answer to the nearest tenth. tan 12 degrees= ten over (x)

Lorico [155]

Tan(12)=-0.6358599287. That means -0.6358599287 = 10/x so you can swap the x to the other side to make x = 10/-0.6358599287 Which equals -15.7 rounded to the nearest tenth.

Let ∠X and ∠Y be complementary. If sin(X) =

Lena [83]

<h3>Answer:</h3>

sin(Y) = 4/5

<h3>Step-by-step explanation:</h3>

The sine of one of a pair of complementary angles is equal to the cosine of the other. Given that ∠X and ∠Y are complementary, sin(Y) = cos(X) = 4/5.

_____

You can figure this from SOH CAH TOA, the mnemonic that reminds you of the definitions of the trig functions. The adjacent leg for one of the acute angles in the right triangle is the opposite leg for the other angle.

... Sin = Opposite/Hypotenuse

... Cos = Adjacent/Hypotenuse
