Tan(theta)= opposite/ adjacent
tan(35) = opp / 10ft
opp=10 * tan(35)
opp= 7.002 ft tall
Let's begin by listing out the information given to us:
We proceed to combine like terms (the coefficients having the same variable), we have:
Answer:
z = 6
Step-by-step explanation:
sin (9z - 1) = cos (6z + 1)
90 - (9z - 1) = 6z + 1
90 - 9z + 1 = 6z + 1
9z + 6z = 90
15z = 90
z = 6

<span><span>The price p and quantity x sold of a small flat screen television set obeys the demand equation below.
p= - .14x+280
:
a. How much should be charged for the television set if there are 60 television sets in stock? Round to nearest cent
p = -.14(60) + 280
p = -8.4 + 280
p = $271.60
:
b. What quantity x will maximize revenue?
Rev = qty * price
R(x) = x(-.14x+280)
R(x) -.14x^2 + 280x
The axis of symmetry is the qty for max revenue;x = -b/(2a)
x =
x = + 1000 tv's for max rev
:
What is the maximum revenue?
rev = -.14(1000^2) + 280(1000)
rev = -140000 + 280000
rev = $140,000
:
:
c. What price should be charged in order to maximize revenue?
p = -.14x + 280
p = -.14(1000) + 280
p = -140 + 280
p = $140</span><span>
