Answer:
Step-by-step explanation:
If air resistance is neglected, the energy is constant. That means that in every point in the trajectory the energy is the same.
At the point of height h, all the energy is potential and velocity is zero (no kinetic energy)
At point of height h/4, some of the potential energy has transformed in kinetic energy and the velocity is no longer zero. But we know the total amount of energy is the same as the maximum height point.
With that information, we can calculate the velocity v:
Answer:
he because the Spence or bentualy
Answer:
n, h = Naomi's and Hudson's work hours, respectively
n + h = 13
35n +20h = 395
Step-by-step explanation:
We are asked for the number of work hours of Naomi and Hudson. It is convenient to define the variables n and h to represent those hours, respectively. Then the system of equations is ...
n + h = 13 . . . . . . . . . . . . total work hours
35n +20h = 395 . . . . . . total shirts ironed
_____
The solution is Naomi worked 9 hours; Hudson worked 4 hours.
To determine which of the rectangles has a different area, the areas of the four rectangles must be calculated. The rectangle with a different area is rectangle b
The dimension of the 4 rectangles are:
a. length: 4x and width: 4
b. length: 11 and width: x
c. length: 2 and width: 8x
d. length: 16x and width: 1
The area of a rectangle is:
<u>Rectangle (a)</u>
<u>Rectangle (b)</u>
<u>Rectangle (c)</u>
<u>Rectangle (d)</u>
Rectangles (a), (c) and (d) have the same area (i.e. 16x) while rectangle (b) has 11x as its area.
Hence, the rectangle with a different area is rectangle (b).
