Answer:
Time t = 1.39 seconds
Step-by-step explanation:
Given;
Initial velocity v = 20 ft/sec
height equation;
h = -16t^2 + 20t + 6
How long does it take for the disc to be caught 3 feet off the ground;
At this point h = 3
Substituting h = 3 into the height equation;
3 = -16t^2 + 20t + 6
-16t^2 + 20t + 6 - 3 = 0
-16t^2 + 20t + 3 = 0
Solving the quadratic equation;
t = 1.39 or t = -0.14
Since t cannot be negative;
Time t = 1.39 seconds
The population you gave isn't formatted correctly so I'll solve the problem assuming you mean 103,500.
First we find the number of males from the percentage given:
0.56 * 103500 = 57960 males
Subtract the number of males from the total population to get the number of females:
103500 - 57960 = 45540 females
You could solve the problem by finding the percentage of females first. Since there are 56% males, that means there are 100-56 = 44% females.
0.44 * 103500 = 45540
The answer is 45540.
1.) $83.99 * 0.0825= $6.929175 round that to $6.93 add $83.99 +6.93=$90.92
2). $349.65 divided by 7 = $49.95 for each tree
3)V=l*w*h 13*11*16= 2288 cubic feet
Answer:
I don't know what kind of form your assignment wants it in, but the domain (span over the x axis) is -4<=x<=5, and the range is -3<=x<=5. Perhaps write it is as "-4 to 5" for domain and "-3 to 5" for range.
