If f(x) = x2 – 2x, find: X - f(-3) = [?]

Reptile [31]

Did you mean :

f(x) = x² - 2x, find x = -3

f(-3) = (-3)² - 2(-3)

f(-3) = 9 + 6

f(-3) = 15

The trajectory of a flying saucer is given by the vector function r(t) = (5 sin(t))i + (5 cos(t))j + 12tk for t ≥ 0 where coordi

Kipish [7]

Answer:

t0 = 2

Step-by-step explanation:

r' = <5cost,-5sint,12>

ds = $\sqrt{25cos^{2}t+25sin^{2}t+12^2} = \sqrt{25+144} = 13$ dt

So, we want

$\int\limits^x_0 {13} \, dt = 26$
