Which equation is the inverse of 5y+4 = (x+3)^2 + 1/2?

katovenus [111]

we have

$5y+4=(x+3)^{2}+\frac{1}{2}$

Step 1

Swap x and y

$5x+4=(y+3)^{2}+\frac{1}{2}$

Step 2

Solve for y

$5x+4-\frac{1}{2}=(y+3)^{2}$

$(y+3)^{2}=5x+\frac{7}{2}$

Square root both sides

$(y+3)=(+/-)\sqrt{5x+\frac{7}{2}}$

$y=(+/-)\sqrt{5x+\frac{7}{2}}-3$

Step 3

Let

$f(x)^{-1}=y$

$f(x)^{-1}=(+/-)\sqrt{5x+\frac{7}{2}}-3$

therefore

the answer is the option D

$y=-3(+/-)\sqrt{5x+\frac{7}{2}}$

Consider angle θ in Quadrant II, where sinθ = 4/5 . What is the value of cosθ?

Kay [80]

Answer:

3/5

Step-by-step explanation:

sin theta=opposite/hypotenuse

4/5=opposite/hypotenuse

therefore opposite=4 and hypotenuse=5

for adjacent

using pythagoras theorem

a^2+b^2=c^2

opposite^2 + adjacent^2 =hypotenuse^2

4^2 + adjacent^2 =5^2

16 + adjacent^2 =25

adjacent^2 =25-16

adjacent = $\sqrt{9$

adjacent=3

cos theta=adjacent/hypotenuse

=3/5

therefore the value of cos theta is 3/5
