Let x be the width of the cardboard, then the length is x+15. If 5 unches square is cut from each corner, then the new length is x+15-5·2=x+5 and the new width is x-5·2=x-10. The height of the formed box is 5 in. Now you can find the box volume:
.
If the volume of the box is 1,250 cubic inches, then
.
The length of the box is x+5=20+5=25 in. (the negative x is extra, because the length couldn't be negative).
Answer: the length of the box is 25 inches.
Answer:
Step-by-step explanation:
The path covered by the volleyball will be a downward parabola with the vertex being the highest point of the ball.
A general form of a downward parabola is given as:
Where is the vertex of the parabola and 'a' is a constant.
Now, let 'h' be the vertical height and 't' be the time taken.
So, the equation would be of the form:
Now, as per question:
h = 2 seconds, k = 13 feet.
Now, taking a = 1. So, the formula that can be used is:
A) 7480$ will be in the account at the end of one year.
B) $6460 will be in the account at the end of 2 years.
