-- point (1, -2)
-- point (10, 25)
Answer:
(5, 0) and (-3, 0)
Step-by-step explanation:
To find the x-intercepts, let's set y = 0.
0 = x² - 2x - 15
0 = (x - 5)(x + 3) -- To factor x² - 2x - 15, we need to find 2 numbers with a sum of -2 and product of -15; these numbers are -5 and 3.
x - 5 = 0 or x + 3 = 0 -- Use ZPP (Zero Product Property)
x = 5, x = -3
It would half 8 hours to get 4 hours and 20 dogs
Next add the 4 hours and 20 dogs to the 8 hours and 40 dogs so
4+8=12 hours
20+40=60 dogs
So Ken can walk 60 dogs in 12 hours
Answer: 152.46 squared centimeters.
Step-by-step explanation:
- The equation to find the area of the trapezoid is A = ½ (6.6 + 16.5) 13.2
- Distribute ½ into (6.6 + 16.5) . A = (3.3 + 8.25) 13.2.
- Add the numbers inside the parenthesis. A = 11.55 * 13.2
- Multiply 11.55 * 13.2. A = 152.46.
