Given the angle
angle
is equivalent to angle 135 degrees and angle 135 degrees is equvalent to angle 45 degrees in the second quadrant, thus sine is positive but cosine and tangent are negative.
Answer:
4 months.
Step-by-step explanation:
We can write formulas for the amount each person paid after x months. These will be
Brian = 60 + 42.95x
Michael = 0 + 57.95x
So for example, after 1 month Brian will have paid 102.95 for the installation and first month, while Michael will have paid only 57.95 (I put the zero in the equation to make it look like the familiar y-intercept form). We are trying the find the month at which they have paid equal amounts. Solve for x in the equation
60 + 42.95x = 57.95x
60 = (57.95 - 42.95)x
60 = 15x
x = 4
After four months.
1 and 1/8 miles
2 3/4 - 1 5/8
2 6/8 - 1 5/8= 1 1/8
Answer:
Ticket price that maximize revenue is $12
Step-by-step explanation:
The number of spectators per stadium is 62,000
When the price of a ticket is $14, the attendance is 26,000 and the revenue will be; $14* 26,000 = $364,000
When the price of a ticket is $12, the attendance is 31,000 and the revenue will be; $31,000*$12 =$372,000
Maximum revenue is attained through ticket 2, $12
