Solve by using tables. Give each answer to at most two decimal places. –2x2 – 4 = –8x (1 point) 0.59, 3.41 –3.41, –0.59 1.17, 6.
GenaCL600 [577]

Answer:

x=3.414 and x=0.59 is the desired answer.

Step-by-step explanation:

We are given a quadratic equation as : -2x^2-4=-8x\\=> 2x^2-8x+4=0

on dividing both side by 2 we have the equation as

x^2-4x+2=0

on solving for the roots of the equation using the quadratic formula we get that x=2\pm \sqrt{2}

x=2+\sqrt{2} and x=2-\sqrt{2}

x=2+1.414 and x=2-1.414

Hence , x=3.414 and x=0.586≈0.59.

A tower that is 111 feet tall casts a shadow 126 feet long. find the angle of elevation of the sun to the nearest degrre
Sergeeva-Olga [200]
The angle here is an acute angle at ground level.  Then the side adjacent to this angle is 126 feet.  The opp. side is the tower, 111 feet tall.

Then   

tan theta = opp / adj = 111 / 126.  Using the inverse tangent function, we find that the measure of the angle is 0.722 radian or 41 degrees (to the nearest degree).
