Write in vertex form (by completing the square)y=4x2+40x+96

Answers

$y=4x^2+40x+96\n \n The \ vertex \ form \ of \ the \ function \ is: \n \ny = a(x - h)^2 + k \n \nvertex =(h, k) \ is \ given \ by: \n \nh = (-b)/(2a) , \ \ \ k = c -(b^2)/(4a) \n \na=4 , \ \ b=40 , \ \ c=96$

$h = (-40)/(2 \cdot 4)=(-40)/(8)=-5 \n \n k = 96 -(40^2)/(4 \cdot 4) =96-(1600)/(16) =96-100=-4 \n \n y = 4(x - (-5) )^2 + (-5)=4(x +5 )^2 -5$

A 10 ft pole has a support rope that extends from the top of the pole to the ground. The rope and the ground form a 30 degree angle. How long is the rope, rounded to the tenth place? A. 20.0 B. 17.3 C. 11.5 D 3.0 (All in ft.)

Answers

Answer:

The length of rope is 20.0 ft . Hence, option (1) is correct.

Step-by-step explanation:

In the figure below AB represents pole having height 10 ft and AC represents the rope that is from the top of pole to the ground. BC represent the ground distance from base of tower to the rope.

The rope and the ground form a 30 degree angle that is the angle between BC and AC is 30°.

In right angled triangle ABC with right angle at B.

Since we have to find the length of rope that is the value of side AC.

Using trigonometric ratios

$\sin C=\frac{\text{perpendicular}}{\text{hypotenuse}}$
