Annette [7]

Answer:

$\cos'(z) = -\sin(z)$

Step-by-step explanation:

According to the information given by the problem

$\sin(z) = {\displaystyle \frac{e^{iz} - e^{-iz} }{2i} }$

$\cos(z) = {\displaystyle \frac{e^{iz} + e^{-iz} }{2} }$

Now, if you compute the derivative of $\cos$ you get that

$\cos'(z) = {\displaystyle \frac{ ie^{iz}-i e^{iz} }{2} } = {\displaystyle \frac{ i ( e^{iz}- e^{iz} )}{2} }\\\\= {\displaystyle \frac{ i ( e^{iz}- e^{iz} )}{2} } *\frac{i}{i} }\\\\= {\displaystyle - \frac{ e^{iz}- e^{iz} }{2i} } = -\sin(z)$

The square root of 36 is 6 so just write

2 × (6) +9
so
12 + 9

Olivia and Kalina are running a lemonade stand for one weekend. They sell lemonade for $0.75 per cup. On Saturday, they sell 37

Sergeeva-Olga [200]

Answer:

a) no

b) yes

c) 0.75(37 + c) ≥ 45

Step-by-step explanation:

lemonade = $0.75 per cup

Saturday sales = 37 cups

Let c = number of cups sold on Sunday

⇒ Total weekend sales = 0.75(37 + c)

a) No, they will not reach their goal of making at least $45

If c = 12:

Total weekend sales = 0.75(37 + 12)= 0.75 x 49 = $36.75

$36.75 < $45

b) Yes, they will reach their goal of making at least $45

If c = 25:

Total weekend sales = 0.75(37 + 25)= 0.75 x 62 = $46.50

$46.50 > $45

0.75(37 + c) ≥ 45
