Well we know that:
Volume = l×w×h
so that means:
40 = l×w×h
Well if the length is doubled that means
New Volume = 2l×w×h or
New Volume = 2×l×w×h
Well since we know from our original equation that 40 = l×w×h, we can substitute it into this new volume equation
New Volume = 2×l×w×h
New Volume = 2×(40)
New volume = 80 cm³
Answer:
See below
Step-by-step explanation:
<u>20% loss a year with initial value of £6000 can be shown as function:</u>
V(t) - is the value after t years
a) t = 1 year
b) t = 3 years
- V(3) = 6000*0.8^3 = £3072
c) t = 8 years
- V(8) = 6000*0.8^8 = £1006.63
Answer:
The radius vector is (-8, 7) and (-1 , 5).
Step-by-step explanation:
Determine the radius vector of the midpoint of the segment that is formed by joining the points (-8, 7) and (6, 3).
The end points are (- 8, 7) and (6, 3) .
The mid point is given by
So, the radius vector is (-8, 7) and (-1 , 5).
I believe it’s B because everything equals 180 and then 180-70=10
I believe the answer is c
