Answer:

Step-by-step explanation:

The difference formula for cosine is

cos(x - y) = cosxcosy + sinxsiny

Consider

cos75 = cos(120 - 45)°, then

cos(120 - 45)°

= cos120°cos45° + sin120°sin45° → C

MArishka [77]

$The\ cone\ that\ has\ the\ same\ base\ and\ height\ as\ the\ cylinder\\states\ \frac{1}{3}\ of\ the\ cylinder.\\\\The\ probality\ of\ choosing\ a\ point\ inside\ a\ cylinder\ not\ inside\\the\ cone\ is\ equal\ to\ \frac{2}{3}.$

For the function P(x) = x3 − 9x, at the point (2, −10), find the following. (a) the slope of the tangent to the curve (b) the in

Shalnov [3]

Answer:

3, in both a), b)

Step-by-step explanation:

a) The slope of the line tangent to the curve that passes through the point (2,-10) is equal to the derivative of p at x=2.

Using differentiation rules (power rule and sum rule), the derivative of p(x) for any x is $p'(x)=3x^2-9$ . In particular, the value we are looking for is $p'(2)=3(2^2)-9=12-9=3$ .

If you would like to compute the equation of the tangent line, we can use the point-slope equation to get $y=3(x-2)-10=3x-16$

b) The instantaneus rate of change is also equal to the derivative of P at the point x=2, that is, P'(2). This is equal to $p'(2)=3$ .
