Answer:
16m/s
Step-by-step explanation:
distance travelled from L to M = 6 x 10 = 60m
distance travelled from M to N = 160 - 60 = 100m
time taken to travel from M to N = 100/25 = 4 seconds
average speed = total distance / total time = 160m / (6 + 4) seconds = 16m/s
hope that helps!
this is a question on speed, distance and time. I have a formula for it up in my insta page (learntionary) if you need it :)
Take the deritive
y'=-3sinx
find whre it equals 0
it equals 0 at -pi, 0, pi, etc
find whre it changes from negative to positive
at -0.5pi, the derivitive is positive
at 0.5pi, the deritivie is negative
changes from positive to negative at x=0
that means that the max values are at pi and -pi in 2pi intervals
-pi, pi, 3pi, 5pi,etc
the min y value is -3
so the minimum(s) are/is at (2aπ,-3) where 'a' is an integer
Answer:
I assume you mean x^2 - 14x + 48. To factor this you want to find a number that adds to -14 and multiplies to 48. That means it'll have to be two negative numbers.
-6*-8 = 48
-6 + (-8) = -14
Your factored expression is (x - 6)(x - 8)
if your wanting to know how far the diver will be down you do 240+25 which is 265
265-80=185 (cause the diver swims up)
185+12+30 =227
227-16 =211
the deep see diver is at 211 meters below the surface
