c = cost
h = # of half-dozens ordered
c = $8.50h + $1 is the correct answer.
8(4n + 13) = 6n
Use distributive property so :8 (4n) = 32n and 8(13) = 104
32n + 104 = 6n
Subtract 32n from each side and you will get:
104 = 26n
then you divide each side by 26 and your answer will be:
n = 4
Part (i)
Plug in theta = pi/3 to get
h(theta) = sin(3theta)
h(pi/3) = sin(3*pi/3)
h(pi/3) = sin(pi)
h(pi/3) = 0 ... use a calculator or the unit circle
<h3>Answer: 0</h3>
=================================================
Part (ii)
Plug in h = pi/2
h(theta) = sin(3theta)
h(pi/2) = sin(3pi/2)
h(pi/2) = -1
<h3>Answer: -1</h3>
Answer:
4×⁴+3׳+7ײ-3x+4
Step-by-step explanation:
First remove the parentheses and pair up like terms
4×⁴+3׳+2ײ+5ײ-x-2x+1+3
Then combine the like terms
4×⁴+3׳+7ײ-3x+4
Which is the answer.
