Use the quadratic formula to solve Round irrational solutions to the nearest tenth

Paha777 [63]

Answer:

C. x = -5.6 and x = -1.4

Step-by-step explanation:

The quadratic formula is $x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}$ . Here a=1, b=7, and c=8.

Substitute and you'll have:

$x=\frac{-b+/-\sqrt{b^2-4ac} }{2a} =\frac{-7+/-\sqrt{7^2-4(1)(8)} }{2(1)}=\frac{-7+/-\sqrt{49-32} }{2)}$

$\frac{-7+/-\sqrt{17} }{2}=\frac{-7+/-4.1 }{2}= -1.4, -5.6$

Trigonometric Identities Help

iren [92.7K]

Recall that

$\sin^2\theta+\cos^2\theta=1$

So we have

$\sin^2\theta=1-\cos^2\theta=1-\left(\dfrac{\sqrt2}2\right)^2=1-\dfrac24=\dfrac12$

So either $\sin\theta=\pm\dfrac1{\sqrt2}=\pm\dfrac{\sqrt2}2$ .

Since $\dfrac{3\pi}2$ , we expect $\sin\theta$ , so we take the negative square root. Then

$\sin\theta=-\dfrac{\sqrt2}2$

This then means we have

$\tan\theta=\dfrac{\sin\theta}{\cos\theta}=\dfrac{-\frac{\sqrt2}2}{\frac{\sqrt2}2}=-1$
