Answer:

amplitude = 3

period = $\frac{2\pi }{3}$

Step-by-step explanation:

Comparing the equation with the general equation :

$f(x) = A cos(Bx + c ) + D$

Where :

A = amplitude

period = $\frac{2\pi }{B}$

D = vertical shift

Therefore : with the comparison :

amplitude = /-3/ = 3

period = $\frac{2\pi }{3}$

I really need help with these 2 geometry questions tysm

qwelly [4]

Answer:

180 + 9 - 4 = 185

5x = 185

185/5= 37

A = 37 X 2 - 9 = 65

B = 37 X 2 + 4 = 78

C = 37

A + B + C = 180

65 + 78 + 37 = 180

A = 65 degrees

B = 78 degrees

Please show the steps for this question <br> Divide z4 by z-3

dsp73

Z^4 / z^-3 = z^7 - when you divide numbers written in exponential form, you keep the base and subtract the exponents. z^4 divided by z^-3 = z^ (4- (-3)) = z^7.
