Answer:

It's D. The initial value of y is 3 because 6,9 and 12 are 3 digits apart, and it always is Y over X

D
you can also write it as y = - 3/2x + 3

Answer:

D

Step-by-step explanation:

f^{-1}(x) means the inverse. The inverse is the function reflected over the y=x line. This means the values have been reversed. (x,y)-->(y,x). We are looking for a point that has reversed values from the table.

The table has (1.-5) so the inverse is (-5,1) or D.

2.=c.\\\\2\sin4x\cos4x=2\sin(2\cdot4x)=2\sin8x\\\\Used:\\\sin2\alpha=2\sin\alpha\cos\alpha

1.=b.\\\\\csc x-\sin x=\dfrac{1}{\sin x}-\dfrac{\sin^2x}{\sin x}=\dfrac{1-\sin^2x}{\sin x}=\dfrac{\cos^2x}{\sin x}\\\\=\dfrac{\cos x\cos x}{\sin x}=\cos x\cdot\dfrac{\cos x}{\sin x}=\cos x\cot x\\\\Used:\\\csc x=\dfrac{1}{\sin x}\\\\\sin^2x+\cos^2x=1\to\cos^2x=1-\sin^2x\\\\\cot x=\dfrac{\cos x}{\sin x}

3.=a.\\\\\dfrac{\sin x-1}{\sin x+1}=\dfrac{\sin x-1}{\sin x+1}\cdot\dfrac{\sin x+1}{\sin x+1}=\dfrac{\sin^2x-1^2}{(\sin x+1)^2}=\dfrac{\sin^2x-1}{(\sin x+1)^2}\\\\=\dfrac{-(1-\sin^2x)}{(\sin x+1)^2}=\dfrac{-\cos^2x}{(\sin x+1)^2}\\\\Used:\\(a-b)(a+b)=a^2-b^2\\\\\sin^2x+\cos^2x=1\to \cos^2x=1-\sin^2x

Find the solution to dy/dt = 7 y<br><br> satisfying<br> y(9) = 5
AVprozaik [17]
\rm \dfrac{dy}{dt}=7y,\qquad\qquad\qquad y(9)=5

I'm not sure what methods you've learned up to this point but one option is to apply separation of variables:

\rm \dfrac{dy}{y}=7dt

and then integrate from there,

\rm ln|y|=7t+c

exponentiate to isolate y,

\rm |y|=e^{7t+c}

Apply exponent rule,

\rm |y|=e^c e^{7t}

rename this e^c as some new constant, perhaps A,

\rm \pm y=A e^{7t}\qquad\qquad A>0

This A can only be positive, non-zero, but absorbing the plus/minus fixes that restriction,

\rm y=A e^{7t}\qquad\qquad A\ne0

Use your initial information to solve for this unknown value A,

\rm y(9)=A e^{7\cdot9}=5

solving for A, dividing by the exponential,

\rm A=5e^{-63}

So we get a final result of

\rm y(t)=5e^{-63}e^{7t}

apply exponent rule again to get a better looking answer, and factor,

\rm y(t)=5e^{7(t-9)}

Lemme know if too confusing.
