To find the measure of a singular window we need to find the area which is length times width. so that's 2.75(4) which is 11 square feet. However, Kevin has four windows which means he needs 11(4) square feet for all the windows. Which would mean Kevin needs 44 sqaure feet.
<span>The vertex of the parabola is the highest or lowest point of the graph.
</span><span>y=-4x^2+8x-12 = -4 (x^2 -2x +3)
Lets work with this now: </span>x^2 -2x +3
x^2 -2x +3 -> what is the closeset perfect square?
x^2 -2x +1 = (x-1)^2
So
x^2 -2x +3 = (x-1)^2 +2
Replacing to original
y=-4x^2+8x-12 = -4 (x^2 -2x +3) = -4 ((x-1)^2 +2) = -4 (x-1)^2 - 8
The min or max point is where the squared part = 0
So when x=1 , y= -4*0-8=-8
This will be the max of the parabola as there is - for the highest factor (-4x^2)
The max: x=1, y= -8
Answer:
A
Step-by-step explanation:
Answer:
2. 180-115 = <u><em>65</em></u>
3. angle = 90-37 = <em><u>53</u></em>
4. angle = 90 - 15 = <em><u>75</u></em>
5. angle = 90-43 = <em><u>47</u></em>
6. 109+71 = 180 = S
7. 19+71 = 90 = C
8. 89+1 = 90 = C
9. 34+56 = 90 = C
10. 75+75 = 150 = N
11. 16+74 = 90 = C
12. 90+90 = 180 = S
13. 65+115 = 180 = S
Hope this helps
Answer:
(A) Is right
Step-by-step explanation:
put X= -2. in y = X+3
to get y 's value
Y = -2+3
= 1
therefore, your solution is ( -2,1)
