Answer:
f(-5)= -17
Step-by-step explanation:
just put -5 where x is
f(x)=3x-2
f(-5)= 3(-5)-2
f(-5)= 3*-5-2
f(-5)= -15-2
f(-5)= -17
Answer:
Step-by-step explanation:
From our knowledge of derivatives we use the product rule approach, the product rule is stated below
For f(x)=u(x)v(x) the derivative is express as
hence from the question f(x)=2xlnx,
we can assign u(x)=2x and v(x)=lnx
also the derivative of u(x)=2x is simply
and the derivative of v(x)=lnx can be express using the general log derivative i.e
hence we have
if we substitute value into the general product expression stated earlier we arrive at
The original fire department is 3 units wide and 4 units long.
The new fire deportment is also 3 units wide, so to be congruent, it needs to be 4 units long.
Point C would be (1,-5)
Point D would be (4,-5)
