Answer:
x= 3/2
Step-by-step explanation
subtract 3 from both sides and then divide what you get by 4
hope this helps
This is all about right triangles, assuming the tower is not the leaning tower of pisa! The tower is our height of the right triangle, the base of our triangle is the distance Nadia is from the tower, and the reference angle is 30 (the base angle that is NOT the right angle). The tower is opposite this reference angle, and the side 60 is adjacent to this angle, so we will use the tangent ratio, the trig identity that relates the side opposite the reference angle to the side adjacent to it.
. Solving for x we get x = 60 tan(30°). On our calculators that gives us that x = 34.64. That's how tall the tower is.
Answer:
B. Multiply (60 − 2x) and (2 + 0.25x) to create the equation y = -0.5x2 + 11x + 120
Step-by-step explanation:
x is the number of price increases of 0.25 each, so (2 + 0.25x) will be the price after x increases.
2 cups remain unsold for every increase in price, so for x increases, 2x cups remain unsold. Then the number sold is (60 -2x).
Revenue is the product of price and quantity sold, so is ...
... revenue = (60 -2x)(2 +0.25x) . . . . . . matches selections A or B
The product of these binomials is ...
... 60·2 +60·0.25x -2x·2 -2x·0.25x
... = -0.5x² +11x +120 . . . . . . . . . . . . . . . . matches selection B
