Answer:
Minimum unit cost = 5,858
Step-by-step explanation:
Given the function : C(x)=x^2−520x+73458
To find the minimum unit cost :
Take the derivative of C(x) with respect to x
dC/dx = 2x - 520
Set = 0
2x - 520
2x = 520
x = 260
To minimize unit cost, 260 engines must be produced
Hence, minimum unit cost will be :
C(x)=x^2−520x+73458
Put x = 260
C(260) = 260^2−520(260) + 73458
= 5,858
Answer:
Hope it helps!
Step-by-step explanation:
Sub y=5x into y=2x+3
so
5x=2x+3
3x=3
x=1
plug x=1 into y=5x
y=5
Checking work
Plug (1,5) into y=2x+3
5=2(1)+3
5=5
Plug (1,5) into y=5x
5=5(1)
5=5
Answer:
See answer below
Step-by-step explanation:
For the first expression
3 x (x - 2) + 2 = 3 x^2 - 6 x + 2
evaluated at x= 4 we get: 26
and for x = 5 we get 47.
For the second expression
2 x^2 + 3 x - 18
we get the exact same values when doing the evaluation at these two points.
Based on those results, one may think the expressions may be equivalent, but they are not equivalent. Because at any other x-value, their results are different. See for example that for x = 0 the first one gives "2" while the second one gives -18.
I’d like to answer the but What angle ??
60 meters
4 seconds
To find the unit rate, divide the distance by the time.
60/4=15meters per second= 15m/s
