6 0

Answer:

A.

Step-by-step explanation:

If R(-2), then x = -2. Just plug in -2 for x. -2^2 - 3(-2) - 1 = 4 + 6 - 1 = 10 - 1 = 9. The answer is 9.

Find tan theta if theta is an angle in standard position and the point with coordinates (4,3) lies on the terminal side of the a
Karolina [17]

Answer: 0.75

Step-by-step explanation:

We can do this by drawing a terminal side in a standard position and then drawing the associated triangle. We then use the Pythagoras theorem to find the missing side the hypotenuse. Then, this will give a Pythagorean Triplet of 3, 4 and 5.

We now have a triangle with the values of:

x = 4

y =3

h^2= 4^2 + 3^2

h^2 = 16 + 9

h^2 = 25

h = 5

h = 5

Tangent = opposite/adjacent

= y/x

= 3/4

= 0.75

What is the answer to this calculus problem???<br><img src="https://tex.z-dn.net/?f=%20%5Cfrac%7Bd%7D%7Bdx%7D%20%28e%20%7B%7D%5E
Len [333]

Answer:

see explanation

Step-by-step explanation:

Differentiate using the product rule

Given y = f(x)g(x), then

\frac{dy}{dx} = f(x). g'(x) + g(x). f'(x)

here f(x) = e^{x} ⇒ f'(x) = e^{x}

g(x) = cosx ⇒ g'(x) = - sinx

Hence

\frac{dy}{dx} = e^{x}(- sinx) + cosx e^{x}

                                   = e^{x}cosx - e^{x}sinx
