Answer:
It would take approximately 8.82 sec for a penny to strike the person.
Step-by-step explanation:
Given:
Height of the building = 1250 feet
Height of the person = 6 feet.
Modeled equation is
We need to find the time required 't' for the penny to strike the person.
Solution:
to find the time required 't' for the penny to strike the person we will substitute;
h ⇒ height of the person.
So we get;
Now Combining the like terms we get;
Dividing both side by 16 using division property we get;
Now taking square root on both side we get;
Hence It would take approximately 8.82 sec for a penny to strike the person.
Answer:
58 at the point (9,8)
7 at the point (1, 1)
Step-by-step explanation:
The maximum points will be found in the vertices of the region.
Therefore the first step to solve the problem is to identify through the graph, the vertices of the figure.
The vertices found are:
(1, 10)
(1, 1)
(9, 5)
(9, 8)
We look for the values of x and y belonging to the region, which maximize the objective function . Therefore we look for the vertices with the values of x and y higher.
(1, 10), (9, 5), (9, 8)
Now we substitute these points in the objective function and select the one that produces the highest value for f (x, y)
The point that maximizes the function is:
with
Then the value that produces the minimum of f(x, y) is (1, 1)
Answer:
We only need to calculate the 15% of 44.99 and 49.99 and sum them, for that, we have to multiply each number by 0.15:
44.99 * 0.15 + 49.99 * 0.15 = 14.27
He saved 14.25 (you should put the unit it's).
We could also have done a rule of three (which is what we have really did before)
44.99 - 100%
x - 15%
x = =. 6.75
49.99 - 100%
x - 15%
x = = 7.5
6.75 + 7.5 = 14.25
