No. When you run in to questions like this, it is often helpful to substitute some numbers in there to see
Let's let x = 4
2*3^4 = 6^4 ?????
162 = 1296 No! so 2*3^x does NOT equal 6^x
One deer = dr
Tiger rate = 1 dr/ 2hr
Fox rate = 1dr/ 3hr
Wolf rate = 1 dr/6hr
To eat 1 dr how long ?
1 dr / (1dr/2hr + 1dr/3hr + 1dr/6hr) = 1/(1/2+1/3+1/6) = 1/(6/6) = 1Hour
Another method: Using Amnesia's nice picture , you can see that the now divided triangle has angles of 30 60 90
Use law of sines sin60/b = sin 30/10 ('10' comes from dividing one '20' side in half = 10)
solve for b = 17.3205
Hey Melof=dy.... No offense was taken......that is a problem with texts....they lack tone and volume: hard to tell what someone intends at times. I was glad they answered my f/u Q ! G'Day !
x = -3 cos (-135) = 2.121
y = -3 sin (-135) = 2.121
'b' is the y-intercept
Where the y-intercept occurs is where x=0
if you sub x= 0 into y = mx+b you will get y=b which is the y-intercept. 'm' is the slope of the line.
x^2 +4 = 0
x^2 = -4
x^2 = (-1)(4)
x = +- 2 i
I am not sure to what you are referring..... can you clarify?
If you just use the calculator: (-8)(3) = -24
