A 6.3<br> B 7.5<br> C 6.7<br> D 6.5

Arlecino [84]

So in this case use sine to figure this out.

To convert 48 to the ratio, you gotta use a calculator unless you've memorized everything. do sin(48), which equals about 0.74.

Since Sin is opposite / hypotenuse, 5/h must equal 0.74

So do 5 / 0.74 to get about 6.76 as your answer.

Please solve the following quadratic equation and show your work: x^2-2x+6=0

hichkok12 [17]

$ax^2+bx+c=0\\\\\Delta=b^2-4ac\\\\if\ \Delta > 0\ then\ exist\ two\ solutions\\\\x_1=\dfrac{-b-\sqrt\Delta}{2a}\ and\ x_2=\dfrac{-b+\sqrt\Delta}{2a}\\\\if\ \Delta =0\ then\ exist\ one\ solution\ x_o=\dfrac{-b}{2a}\\\\if\ \Delta < 0\ then\ no\ solutions$

We have:

$x^2-2x+6=0\\\\a=1;\ b=-2;\ c=6\\\\\Delta=(-2)^2-4\cdot1\cdot6=4-24=-20 < 0$

Answer: NO SOLUTIONS.
