Answer:
7) Option A
10) Option J
Step-by-step explanation:
7). From the graph attached,
Coordinates of S → (-5, 6)
Coordinates of U → (2, -6)
If the given points are reflected by the rule,
(x, y) → (-x, y)
[Change the sign of x - coordinates of S and U]
Coordinates of S' → (5, 6)
Coordinates of U' → (-2, -6)
Option A will be the answer.
10). Coordinates of the vertices of the ΔXYZ,
X → (6, 9)
Y → (9, 5)
Z → (4, 5)
If the vertices of this triangle are translated 3 units left and 4 units down,
Rule for the image points will be,
(x, y) → (x - 3, y - 4)
By this rule coordinates of the image points will be,
X(6, 9) → X'(3, 5)
Y(9, 5) → Y'(6, 1)
Z(4, 5) → Z'(1, 1)
Therefore, Option J will be the answer.
Answer:
3 because your domain should not repeat
The correct answers are letters B and C, w<11 and w+c≤32.
Well, the formula for circumference is:
![2πr](https://tex.z-dn.net/?f=2%CF%80r)
We already know that
![r=12](https://tex.z-dn.net/?f=r%3D12)
, and that
![π=3.14](https://tex.z-dn.net/?f=%CF%80%3D3.14)
(Approximately), so we have everything we need.
Substitute:
![2πr](https://tex.z-dn.net/?f=2%CF%80r)
![=2(3.14)(12)](https://tex.z-dn.net/?f=%3D2%283.14%29%2812%29)
![=(24)(3.14)](https://tex.z-dn.net/?f=%3D%2824%29%283.14%29)
![=75.36](https://tex.z-dn.net/?f=%3D75.36)
The circumference of the bicycle wheel is approximately 75.36 inches.
Hope this helped!
