Question

Need help please answer ASAP!

Answer 1

#1

Length of diameter

• √(2-2)²+(2-12)²
• √(-10)²
• 10units

Length of radius=10/2=5

#2

• 3x²-34x-24=0
• (x-12)(3x+2)=0
• x=12 or -2/3

Solution set

• {-2/3,12}

Answer 2

Answer:

See below ~

Step-by-step explanation:

Question 18

• Diameter = Difference in y-coordinates
• Diameter = 12 - 2 = 10
• We know : Radius = Diameter/2
• Radius = 10/2
• Radius = 5 cm
• (1) 5 cm

Question 19

• 3x² - 34x - 24 = 0
• (3x + 2)(x - 12) = 0
• Solution set = {-2/3, 12}
• (3) {-2/3, 12}
