Answer:
A rotation ____on the coordinate plane________ a figure around a fixed point called the center of
___rotation_____________.
Suggest you use some punctuation here: "The h<span>eight of window is 0.6 feet less than 2.5 times it width. The height of window is 4.9 feet. Find the width of the window."
height of window = 4.9 feet = 2.5(width) - 0.6 feet.
simplify this equation by adding 0.6 feet to both sides of the equation:
4.9 feet + 0.6 feet = 2.5 (width); find width:
5.5 feet = 2.5 (width)
Dividing both sides of this equation by 2.5 will result in an equation for the width of the window, in feet.</span>
the coordinates where the bridges must be built is
and
.
<u>Step-by-step explanation:</u>
Here we have , a road follows the shape of a parabola f(x)=3x2– 24x + 39. A road that follows the function g(x) = 3x – 15 must cross the stream at point A and then again at point B. Bridges must be built at those points.We need to find Identify the coordinates where the bridges must be built. Let's find out:
Basically we need to find values of x for which f(x) = g(x) :
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Value of g(x) at x = 3 : y=3x -15 = 3(3)-15 = -6
Value of g(x) at x = 6 : y=3x -15 = 3(6)-15 = 3
Therefore , the coordinates where the bridges must be built is
and
.
