The answer should be x=-2
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>
Drawing this square and then drawing in the four radii from the center of the cirble to each of the vertices of the square results in the construction of four triangular areas whose hypotenuse is 3 sqrt(2). Draw this to verify this statement. Note that the height of each such triangular area is (3 sqrt(2))/2.
So now we have the base and height of one of the triangular sections.
The area of a triangle is A = (1/2) (base) (height). Subst. the values discussed above, A = (1/2) (3 sqrt(2) ) (3/2) sqrt(2). Show that this boils down to A = 9/2.
You could also use the fact that the area of a square is (length of one side)^2, and then take (1/4) of this area to obtain the area of ONE triangular section. Doing the problem this way, we get (1/4) (3 sqrt(2) )^2. Thus,
A = (1/4) (9 * 2) = (9/2). Same answer as before.
Answer:
2
Step-by-step explanation:
Divide 3.4 by 1.7 and you get 2
Answer:
Two different transformations happen. Rotation/Reflection and translation (I say rotation/reflection because they can both put the parabola where it is after being transformed)
(Rotation- 180 degrees)
(Reflection across its it's starting point)
Translation- pushed up 4 points from negative 4 to 0 on the y-axis
When you put the parent function into a graph it is positive so the u is opening upward and starts at -4. Both sides of the u go through the points (0,0)and (4,0).
But in the transformed function is negative so the u opens downward. The sides going through the points (0,-4) and (4,-4)
I hope this makes sense
