Solve for a -8 = a(2+5)^2 +41 A. -1 B. 1 C. -2 D. 2

mario62 [17]

Answer:A

Step-by-step explanation:

-8=a(2+5)^2 + 41

-8=a x 7^2 + 41

-8=a x 7 x 7 +41

-8=49a+41

Collect like terms

-8-41=49a

-49=49a

Divide both sides by 49

-49/49=49a/49

-1=a

a=-1

PLEASE HELP, 50 POINTS QUESTION IS IN THE PICTURE

artcher [175]

Answer:

$-\frac{50}{3}$

Step-by-step explanation:

Find dy/dx of the ellipse $25x^{2} +y^{2}=109$ at (2,3)

Using Implicit Differentiation

Differentiate both sides of the equation with respect to x

$25x^{2} +y^{2}=109$

$50x +2y\frac{dy}{dx}=0$

isolate the term dy/dx

$2y\frac{dy}{dx}=-50x$

$\frac{dy}{dx}=-25\frac{x}{y}$

Evaluate at point (2,3)

For x=2, y=3

$\frac{dy}{dx}=-25(\frac{2}{3})$

$\frac{dy}{dx}=-\frac{50}{3}$
