Answer:
96
Step-by-step explanation:
The maximum height reached by the pebble modeled by the quadratic function,
, can be found by finding the vertex.
Let's first find the t-coordinate of the vertex . The max height will correspond to this value of t which means we have to find the h(t)-coordinate.
When comparing
to
, we see that:



We need to evaluate the following to find the t-coordinate of the vertex:




So now to find the correspond h(t)-coordinate, we will need to replace t in
with 1:





Answer:
The length of each rope is 9.93 feet (Approx).
Step-by-step explanation:
As given
Emma, Brandy, and Damian will cut a rope that is 29.8 feet long into 3 jump ropes.
Each of the three jump ropes will be the same length.
Thus


Therefore the length of the each rope is 9.93 feet (Approx).
Answer:
The equation for the total number of strings ordered is
X+Y=80
The equation based on the price of each type of string and the total value of the order is
4.50 x +1.50 y = 225
