Given:
A quadratic function has a line of symmetry at x = –3.5 and a zero at –9.
To find:
The other zero.
Solution:
We know that, the line of symmetry divides the graph of quadratic function in two congruent parts. So, both zeroes are equidistant from the line of symmetry.
It means, line of symmetry passes through the mid point of both zeroes.
Let the other zero be x.
Multiply both sides by 2.
Add 9 on both sides.
Therefore, the other zero of the quadratic function is 2.
Answer:
Time taken by the un powered raft to cover this distance is T = 192.12 hr
Step-by-step explanation:
Let speed of boat = u
Speed of current = v
Let distance between A & B = 100 km
Time taken in downstream = 32 hours
u + v = 3.125 ------ (1)
Time taken in upstream = 48 hours
u - v = 2.084 ------- (2)
By solving equation (1) & (2)
u = 2.6045
v = 0.5205
Now the time taken by the un powered raft to cover this distance
Because un powered raft travel with the speed of the current.
T = 192.12 hr
Therefore the time taken by the un powered raft to cover this distance is
T = 192.12 hr
<h2>Answer:</h2>
The statement that is true about the scenario is:
- The distance traveled depends on the amount of time Marlene rides her bike.
- The function f(t) = 16t represents the scenario.
The time that she rides is represented by 't'
and the distance she traveled is represented by 'd'
Now, it is given that:
Marlene rides her bike at a rate of 16 miles per hour.
This means that the distance she rides in ''t" hours is given by:
Since, speed is the ratio of distance over time and it is given that the speed is: 16 miles per hour.
i.e.
Hence, the distance depends upon time.
i.e. the independent variable is time and the dependent i.e. the output is distance traveled.
Also, the initial value is zero.
i.e. at t=0 we have: d=0
