Open Windows charcter map .... copy from there .....
tan = sin/cos so wherever sin = cos tan = 1
pi/4 and 5pi/4 (45o and 225o )
1 / (4/3) = 3/4
3/ 4 * 4/3 = 1
**** edit ****
2\9-(-4\3+7\8-2) =
2/9 + 4/3 -7/8 + 2 =
17/72 + 96/72 - 63/72 + 144/72 =
(17 + 96 - 63 + 144) / 72
2/9 + 4/3 -7/8 - 2 =
17/72 + 96/72 - 63/72 - 144/72 =
(17 + 96 - 63 - 144) / 72 take it from here !
Another method: x = 585/z y = 630/z
xy = (585 * 630) / z2 = 182 so z = 45
now you can find x and y xz = x(45) = 585 soooo x = 13 etc
15 -7 = 8% difference = $10
8% x = 10
.08x = 10
x = $125
Jenny wrote 5x instead of 4x
You didn't include the parent funtion in your question, so I cannot sketch it BUT
I can tell you #1 the graph will be shifted one unit to the LEFT
#2 the graph will be shifted 5 units DOWN
reduction of 40% means 60% remains
60% x = 36
.6x = 36 solve for x
