Answer:
We're here to help! Let me take this slowly.
44. First, we have the x-coordinate of the vertex to be -b/2a which is 16. Plugging 16 in, we have y-coordinate to be 135.
Notice that it is y=(x-7)(x-1).
So, we can just plug in values for x and y. Once you've got a lot of points, you can connect the dots and see how you can graph it.
The axis of symmetry is the x-coordinate of the vertex, or x=16.
45. Do the same method as mentioned above. I personally think that using transformations are more confusing, but that's just opinion. The axis of symmetry is x=-(-4)/2(-1) = -2, so axis of symmetry is x=-2.
46. We have x=-4 or x = 1/2.
47. We have (y-7)(y-1) = 0 ==> y=7,y=1
48. We have w^2 = 9, so w = +/- 3
49. We have (p-10)(p-3)=0, so p=10, p=3
50. We have (3m+1)(m+3)=0, so m=-1/3, m=-3
Answer:
a
Step-by-step explanation:
It is A'C' because when the figure is dilatted the corresponding figure has " by it.
hopes this helps :)
The diameter of the semicircle is 16 feet.
He calculates that he needs to buy abut 25.12 feet of fencing.
To find amount of fencing we find the circumference of semicircle
Circumference of semicircle = 
Where d is the diameter of the circle
d= 16 given and value of pi is 3.14
Circumference of semicircle = 
=25.12 + 16 = 41.12 feet
Scott's calculation was wrong because he forgot to add the diameter d
Circumference of circle is half way of circle plus the diameter of circle.
Correct amount of fencing = 41.12 feet
I only know (b) and 28 (c)
(b) Multiples of 120= 120,240,360,480,600
Multiples of 150= 150,300,450,600
Both numbers have 600 as their first common multiple so the ANSWER is 600
28. (a) Common factors of 24= 1,2,3,4,6,8,12,24
Common factors of 64= 1,2,4,8,16,32,64
8 is the only common factor for both 24 and 64 so 8 is the ANSWER
