Answer:
w=10
Step-by-step explanation:
8.25+1/4w=10.75
8.25+0.25w=10.75
0.25w=10.75-8.25
0.25w=2.5
w=10
I hope this helps
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
<span>A complex number is a number of the form a + bi, where i = and a and b are real numbers. For example, 5 + 3i, - + 4i, 4.2 - 12i, and - - i are all complex numbers. a is called the real part of the complex number and bi is called the imaginary part of the complex number.</span>
Use the equivalents ...
... 1/3 = 2/6
... 9/18 = 3/6
... 1 = 6/6
First we split the mixed numbers into integer parts and fractional parts, adding each separately.
(5 1/3) + (-3 9/18) = (5 +(-3)) +(1/3 +(-9/18))
... = 2 + (2/6 - 3/6) . . . . . . use the equivalents for 1/3 and 9/18 to have a common denominator (6)
... = 2 - 1/6 . . . . . . . . . . . . the sum of the fractional parts is negative
... = (1 + 1) - 1/6 . . . . . . . . here's how we subtract it from the integer part
... = 1 + (6/6 - 1/6)
... = 1 5/6
