Shortcuts?:)<br> Find dy/dx<br> y=-3x^7
Lostsunrise [7]
Knowing the power rule:
dx*n*x^(n-1) all you'd need to do is bring the 7 down and multiply it by -3, then subtract 1 from 7. Because dx is 1 you don't need to worry about it (you'll use chain rule for that)
So your final answer should be dy/dx= -21x^6

In ΔJKL, the measure of ∠L=90°, JK = 7.3 feet, and KL = 4.7 feet. Find the measure of ∠J to the nearest tenth of a degree.
Yakvenalex [24]

Answer:

40°

Step-by-step explanation:

We can find the  tangent of ∠J using the trigonometrical ratios which may be expressed in the form SOA CAH TOA Where,

SOA stands for

Sin Ф = opposite side/hypotenuses side

Cosine Ф = adjacent side/hypotenuses side

Tangent Ф = opposite side/adjacent side

The hypotenuse is the side facing the right angle while the opposite is the side facing the given angle.

Considering triangle ΔJKL, where ∠L=90°, JK = 7.3 feet, and KL = 4.7 feet

As such, with respect to angle J, JK is the hypotenuse, KL is the opposite side

Hence

Sin J = 4.7/7.3

Sin J = 0.643835616

J = 40.08°
