Answer:
dy/dx
= d/dx [2x² + 5x - 3]
= 4x + 5.
Hence at x = 1, dy/dx = 4(1) + 5 = 9.
The slope of the tangent is 9.
d/dx (3/x)
= d/dx (3x^-1)
= 3 * d/dx (x^-1)
= 3 * [-1 * x^(-2)]
= -3/x².
Answer:
Step-by-step explanation:
F(x)=(5 t^2+t )x to x+3
=5((x+3)^2-x^2)+(x+3-x)
=5(x^2+6x+9-x^2)+3
=5 (6x+9)+3
=30x+48
F'(x)=30
Answer:

Answer:
2.5x10-14
Step-by-step explanation:
0.0000254=2.54*10^-5
0.0000035=3.5*10^-5
0.000255=2.55*10^-4
multiplying them all because volume is equals to
l*b*h
which gives
2.26695×10^-14
It should be 24.5%. If you divide 98 by 400 it's .245. Then multiply it by 100, you get 24.5%.
