Calculate the vertex of the parabola using the equation <br> Please helppp meee :((
Sergio [31]

FACTOR ALL OF THE EQUATIONS INTO "y = (x-h)^2 + k," AND THE EQUATION'S VERTEX IS (h,k)

10. y = (x+2)^2 - 11 --> (-2, -11)

11. y = -(x-4)^2 + 32 --> (4, 32)

12. y = 3(x-1)^2 - 5 --> (1, -5)

13. y = -2(x+2)^2 + 5 --> (-2, 5)

14. y = 2(x+1)^2 - 1 --> (-1, -1)

15. y = -5(x-1)^2 + 8 --> (1, 8)

16. y = 3(x-3)^2 - 26 --> (3, -26)

17. y = (x+5)^2 - 32 --> (-5, -32)

18. y = -(x-3)^2 + 10 --> (3, -10)

Ley y = tan x. (a) Find the differential dy.(b) Evaluate dy and Δy if x = π/4 and dx = −0.1. (Round Δy to four decimal places.)
amm1812

Answer:

Required differential (a) dy=-0.0002\times10^{3} and (b) \Delta y=-0.3370.

Step-by-step explanation:

Given,

y=\tan x

Let, y=f(x)=\tsn x\hfill (1)

(a) To find differential,

dy differentiate (1) we get,

dy=\sec^2 x dx

when, x=\frac{\pi}{4} and dx=-0.1, then

dy=\sec^2(\frac{\pi}{4})\times (-0.1)=-0.2

dy=-0.0002\times 10^{3}    (Correct upto four decimal places)

(b) To find,

\Delta y=\Delta f(x)=f(x+h)-f(x)    ( where h=dy)

when x=\frac{\pi}{4}, dx=h=-0.1

\therefore \Delta y=\tan (\frac{\pi}{4}-0.2)-\tan \frac{\pi}{4}

=-0.3370

Correct upto four decimal places.
