What is the value of this expression when x= -4 and y= 64? -437 + 12 O A O OB. OC. OD. -48

1 answer:

4 0

The correct answer when you plug in x and y values is -32 however that answer is not there . Perhaps they only wanted it before combining all like terms ? So again it really should be -32 , but if force yo pick
an answer from the choices I would pick -16

Find the derivative of the function. y = sin−1(6x + 1)

liraira [26]

If you don't know the derivative of the inverse of sine, you can use implicit differentiation. Apply sine to both sides:

$y=\sin^{-1}(6x+1)\implies\sin y=6x+1$

(true for <em>y</em> between -π/2 and π/2)

Now take the derivative of both sides and solve for it:

$\cos y\dfrac{\mathrm dy}{\mathrm dx}=6$

$\dfrac{\mathrm dy}{\mathrm dx}=6\sec y$

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac6{\cos\left(\sin^{-1}(6x+1)\right)}$

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac6{\sqrt{1-(6x+1)^2}}$

Anna has been adding $30 to her savings account every month. Which model could represent the money in Anna’s savings account (y)

RSB [31]

Y=30x.
Whatever the number of months is you times by 30, the amount she added each month. If she had started with a certain amount you would add that to the equation. Y is the total money in the account.
