could someone help me out with 14? i tried it and I get that it uses chain rule and second derivative but I’m so lost please hel
iogann1982 [59]

Answer:

None of these (see below).

Step-by-step explanation:

y = m cos pt - n sin pt

Using the chain rule:

dy/dt =  m * -sin pt * p - ( n * cos pt * p)

= -mp sin pt  -  np cos pt.

dy/dt^2 = -mp * -cos pt * p - (np * - sin pt * p)

= mp^2 cos pt + np^2 in pt.

K(x)= -3x - 3; find k(-2)
Anastaziya [24]

Answer:

\huge{k( - 2)} = 3

Step-by-step explanation:

K(x)= -3x - 3

To find the value of k substitute the value of k that's -2 into the original expression and solve for the value of k.

That's

k( - 2) =  - 3( - 2) - 3 \\  = 6 - 3 = 3

We have the final answer as

<h3>k(-2) = 3</h3>

Hope this helps you

A line contains the points (3, -4) and (0, 2). What is the equation of this line in slope-intercept form?
Lera25 [3.4K]

Answer:

B. y = –2x + 2

Step-by-step explanation:

First, find the <em>rate of</em><em> </em><em>change</em><em> </em>[<em>slope</em>]:

-y₁ + y₂\-x₁ + x₂ = m

\frac{4 + 2}{-3 + 0} = -\frac{6}{3} = -2

In this case, the y-intercept of [0, 2] is ALREADY given to you, so we would not have to go further.

I am joyous to assist you anytime.
