Answer:
a. where's the function?
b. x + y = 12: Yes
x=3-y : Yes
y=8+x^2: Yes
Step-by-step explanation:
b. meet demand: 2 inputs -> 1 output.
So, here is exactly how you would do this:
-3m-2e if m=6 and e=1
We know the values of e and m. We can plug these in to evaluate.
Simply replace the number 6 in place of m and 1 in place of e in -3m-2e
-3m-2e Original expression
-3(6)-2(1) With values plugged in
-18-2 Simplified
-20 Final answer
Our final answer would therefore be: -20
Answer:
the equation for v is v = 250 km/h * [1- e^(-kt) ]
Step-by-step explanation:
since the acceleration "a" is the rate of change of velocity "v" with respect to the time "t", we have
a= dv/dt= k*(250 - v)
thus
dv / (250 - v) = k*dt
if we proceed then to the indefinite integration in both sides
∫dv / (250 - v) = ∫k*dt
- ln (250-v) = k*t +C , where C= constant
if we know that at t=0 , v(t=0)=0 , then
- ln (250-0) = k*0 +C
- ln 250 = C
replacing C in the original equation:
- ln (250-v) = k*t - ln 250
ln [(250-v)/250] = -k*t
v = 250 km/h * [1- e^(-kt) ]
We know 350 = 5t^2 + 10
So 5t^2 = 340
t^2 = 68
Take the square root of both sides to get t = 8.246 years.
Answer:
8
Step-by-step explanation:
10x-2x=8x
60+4=64
8x=64
x=8
