How to factor: 6x^5-11x^4-10x^3-54x^3+99x^2+90x

1 answer:

8 0

6x^5 - 11x^4 - 10x³ - 54x³ + 99x² + 90x

6x^5 - 11x^4 + (-10x³ - 54x³) + 99x² + 90x collect like terms

6x^5 - 11x^4 - 64x³ + 99x² + 90x simplify

hope this helps, God bless!

To find the height of a pole, a surveyor moves 120 feet away from the base of the pole and then, with a transit 8 feet tall, mea

Vikki [24]

Refer to the figure.
Let AB be the height of the pole; CD be the height of the transit; BC is the distance from the base of the pole to the transit.

Triangle ADE is a right triangle with angle D measuring 26 degrees. Using the tangent function, we have
$tan\:26^{\circ} =\frac{AE}{120}$
So,
$AE=120\:tan\:26^{\circ}$
$AE=58.53\:$

Therefore, the overall height of the pole is
$AB=58.53+8=66.53\:feet$

The height of the pole is 66.53 feet.
