Answer:
See below ~
Step-by-step explanation:
<u>Question 18</u>
- Diameter = Difference in y-coordinates
- Diameter = 12 - 2 = 10
- We know : Radius = Diameter/2
- Radius = 10/2
- Radius = 5 cm
- <u>(1) 5 cm</u>
<u></u>
<u>Question 19</u>
- 3x² - 34x - 24 = 0
- (3x + 2)(x - 12) = 0
- Solution set = {-2/3, 12}
- <u>(3) {-2/3, 12}</u>
Answer:
Solution given:
p=6in
b=8in
By using Pythagoras law
diameter=
=10in
r=5in
Now
Area of shaded region=area of semi circle- area of triangle
=½(πr²)-½p*b
=½(π×5²)-½(6*8)
=15.269
=15.3in² is a required answer.
The correct answer is B. Reflection across the line y = -x followed by a rotation 180° counterclockwise about the origin.
