Find the indicated quantities for y equals f (x )equals 3 x squared. (A) Simplify StartFraction f (3 plus Upper Delta x )minus

torisob [31]

Answer:

Step-by-step explanation:

Given that a function f(x) is given as

$y=f(x) = 3x^2$

A) $f(x+ \Delta x) = 3((x+ \Delta x)^2=3(x^2+2x \Delta x+\Delta x^2)\\f(x) = 3x^2\\f(x+ \Delta x) -f(x) = 6x \Delta x +\Delta x^2$

Now divide by delta x

$\frac{f(x+ \Delta x) -f(x)}{\Delta x}\\=6x+\Delta x$

B) When delta x tends to 0, this becomes

$6x$

(NOte: This is the derivative of f(x))

Find the distance between the points (-21, 17) and (33, 17)

Norma-Jean [14]

Plug it into the distance formula.

d= (sqrt) (x2-x1)^2 +(y2-y1)^2

d= (sqrt) (17-17)^2 + (33-(-21)^2
d=(sqrt) (0)^2 + (33 +21)^2
d= (sqrt) (54)^2
d= (sqrt) 2916
d=54

The distance is 54 units.

I hope this helps!

The wind is blowing N 35.0 degrees W at 1.60 * 10^2 mph. A plane has an engine speed of 3.20 * 10^2 mph. Where should the pilot

Answer: 24.2° SouthWest

Step-by-step explanation:

First step: DRAW A PICTURE of the vectors from head to tail (see image)

I created a perpendicular from the resultant vector to the vertex of the given vectors so I could use Pythagorean Theorem to find the length of the perpendicular. Then I used that value to find the angle of the plane.

Perpendicular (x):

cos 35° = adjacent/hypotenuse

cos 35° = x/160

→ x = 160 cos 35°

Angle (θ):

sin θ = opposite/hypotenuse

sin θ = x/320

sin θ = 160 cos 35°/320

θ = arcsin (160 cos 35°/320)

θ = 24.2°

Direction is down (south) and left (west)
