Answer:
at y = 18 units
Step-by-step explanation:
An arch has the equation y=-2/81x^2+18. Find it’s maximum height
This is a parabolic function
Maximum at the vertex
x = -0/(2*(2/81)) = 0
max at y = 18 units
Answer/Step-by-step explanation:
1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°
2. m<ECF = m<BCD (corresponding angles)
m<ECF = 38° (substitution)
3. m<DCF + m<ECF = 180° (linear pair)
m<DCF + 38° = 180° (substitution)
m<DCF = 180° - 38° (Subtraction property of equality)
m<DCF = 142°
The answer for that word problem is A:41balls
<span>We can say that 600 represents 100% and 12 represents x %. Using the proportion: 600 : 12 = 100 : x. That can also be written as: 600/12 =100/x. Then we will multiply across the known corners and then divide by the third number. 600 x = 12 * 100 600 x = 1,200 x = 1,200 : 600, x = 2. Answer: 12 is 2% of 600.</span>
