Answer:
domain = {x|xER}
range = {y|y≥0,yER}
Step-by-step explanation:
|x| means the absolute value which in this case is the distance from 0. On a graph this function would look like a v and would mean it would have infinite x-values since it is opening upwards in both directions.
For the range the vertex of this function is (0,0), if the x-coordinate were 0 the y-coordinate would be 0 because the absolute distance from 0 is 0. for another x-coordinate say -2 the absolute distance from 0 is 2 meaning the y-value is 0 since y=|x|, making the coordinate (-2,2) meaning the range is every y value must be above 0 since there is no way for the y-value to be negative
Answer:
20
Step-by-step explanation:
the whole angle needs to be 180 degrees 180-100=80 80-20=60 20×3=60 60+20=80 80+100=180
I will take the sugestion, so 85 units per month (100 is full capacity)
so while doing maintinance, the 6 months is wasted, 0 ouput, basically 85*6=510 lost
now we have to see how many months x it takes for the output to match
the output that would have been is
510+85x
the output now is 120x
so
510+85x=120x
minus 85x both sides
510=35x
divide both sides by 35
14.57=x
round up
15 months needed
Answer:
option C is correct
Step-by-step explanation:
We need to find the determinant.
= -1(7*9 - 3*9)-( -3)(4*9 - 3*3) -2(4*9 -7*3)
= -1(63-27) +3 (36 - 9) -2( 36- 21)
= -1(36)+3(27)-2(15)
= -36+81-30
= 15
Option C is correct
