The maximum height is 64ft and the ballon is only in the air for 2 seconds
Answer:
Step-by-step explanation:
x=2,x-2=0
x=8
x-8=0
y=(x-2)(x-8)=x²-2x-8x+16=x²-10x+16
=x²-10x+25-25+16
=x²-10x+25-9
y=(x-5)²+9
axis of symmetry is x-5=0 or x=5

Answer:
519
Step-by-step explanation:
Let's assume that the scores for the national verbal proficiency test follow a normal distribution.
Mean score (μ) = 500
Standard deviation (σ) = 75
According to a Z-score table, the score for the 60th percentile is roughly z = 0.253
For any score "x", the z-score is given by:
For z = 2.53:
The raw score to the 60th percentile is 519.
The measure of VW from the given expressions is 4
<h3>Line segments</h3>
If the point V is on the line Uw, then;
UW = UV + VW
Given the following
VW=x, UV=3x-1 and UW=5x-5
Substitute
5x - 5 = 3x-1+x
5x - 5 = 4x - 1
Collect like terms
x = -1 + 5
x = 4
VW = x = 4
Hence the measure of VW from the given expressions is 4
