Notes:
- The sign of the coefficient of the quadratic equation determines if the vertex is a minimum or maximum. Positive looks like ∪ so has a minimum. Negative looks like ∩ so has a maximum.
- Maximum/minimum height is the y-value of the vertex.
- Time to reach maximum height is the x-value of the vertex (which is also the Axis-Of-Symmetry).
Answer: 4) maximum
5) 20.1 ft
6) 2 seconds
<u>Step-by-step explanation:</u>
4) h(t) = -16t² + 256t
↓
the coefficient is negative so it looks like ∩.
Therefore, it has a maximum.
5) h(t) = -16t² + 30t + 6

6) h(t)=-16t²+64t+80

Answer:
5/12
Step-by-step explanation:
There are 7 pink roses and 5 white roses.
Answer:

Step-by-step explanation:
SOHCAHTOA
O =Opposite
A = Adjacent
H = Hpotenuse
If we draw it out we can see that the opposite side is the UT and adjacent side is SU for ∠S.
When an angle is asked for like here is S so the opposite side of the angle is the opposite side. and the angle close to it is the adjacent. The biggest side is the hypotenuse.
Answer:
2.5 bottles or 3 bottles
Step-by-step explanation:
Given that :
Dimension of lot :
22.5 yds by 20.4 yds
Area of lot = 22.5 * 20.4 = 459 yd²
Volume per bottle of herbicide = 12 fl oz
1.1 fl oz combined with water treats an area of 155 ft²
Number of 1.1 fl oz from 12 fl oz that can be obtained : 12 / 1.1 = 10.90
1 yard² = 9 feet²
459 yard² = (459 * 9) = 4131 feet²
Number of 151 feet² that can be obtained from 4131 feet²
4131 feet² / 155 ft²
= 27.3576 times
= 27.3576 / 10.909
= 2.507
This means he'll have to buy a minimum of 3 bottles if a fraction of a bottle can't be purchased.
