Step-by-step explanation:
cos(90) = 0
around this point the cos function "mirrors" with opposite signs. cos(<90) is positive and cos(>90) is negative.
but |cos(90-a)| = |cos(90+a)| for 0 <= a <= 90
75 = 90 - 15
105 = 90 + 15
so, a = 15
and because of
|cos(90-a)| = |cos(90+a)| for 0 <= a <= 90
cos (90-15) = cos(75) = -cos(90+15) = -cos(105)
Answer:
11:
since diagonal are equal of rectangle
QS=RT
4x+6=6x-4
6+4=6x-4x
2x=10
x=10/2
x=5
now
diagonal :4x+6=4*5+6=<u>26</u>
12.
again
QS=RT
9x+12=11x-10
12+10=11x-9x
2x=22
x=11
now
diagonal=9*11+12=99+12=<u>111</u>
Answer:
Each flower cost an equivalent of $5 per flower. To get this answer you have to divide 90 by 18 to get the average cost of the flowers and stuff.

Answer:49,725,000
Step-by-step explanation:
in an average week, the compter is down for 2.75 hours. lost revence per hour is 425,000$
what is the total revenues lost in a 52 week year.
425,000 /2
212500 = 30 mins
106,250 = 15
956.250 = 2 hours and 45 mins
now just time that with 52
49,725,000
