What is measure of cgf?​
Digiron [165]

Answer:

Step-by-step explanation:

A triangle adds up to 180.

180 - 50 = 130

Since both of the missing angles are congruent each of the missing angles is 65 degrees.

130/2 = 65

As per the exterior angle theorem, the measure of the exterior angle is determined by the sum of the opposite interior angles.

65 + 65 = 130

So, the measure of

Find the 57th derivative of y = cos(7x).
mel-nik [20]
                      y = cos(7x)

First derivative = -7sin(7x)

Second derivative = - (7^2)cos(7x)

3rd derivative = (7^3)sin(7x)

4th derivative =  (7^4) cos(7x)

5th derivative = -(7^5) sin (7x)

6th derivative = -(7^6) cos(7x)

nth derivative ?

Analysis and conclusion

If n is multiple of 4 or a number before a multiple of 8 the sign is positive

If n is one or two numbers after a multiple of 4 the sign is negative.

7 is raised to exponent n

if n is odd the function is sin(7x), if n is even the function is cos(7x)

n = 57 => odd, and it is a number after 56 which is a multiple of 4 => negative sign

Therefore, the 57th derivative = - (7^57)sin(7x)
