2n + 2n = 2n squared and 17 + 21 = would be 38
so answer is : 38 + 2n squared
Answer:
It takes 1 second for the tape to reach the ground.
Equation to use:
As explain above, the initial position s 16 ft, there is no initial velocity, so , and the acceleration of gravity is 32 ft/s^2, and should be considered negative [as pointing down in the y-direction], so the equation simplifies to:
In order to find the tima it takes it to hit the ground, we simple solve the equation for t when y(t) = 0 (the tape has reached the ground (zero height in the y-direction):
We select the positive time (+1 second) which is what makes physical sense, since a negative value in time would mean time before the tape was dropped.
So the answer is: It takes 1 second for the tape to reach the ground.
Answer:
The product of w and 3 is greater than 15.
(w x 3)> 15
3w>15
Step-by-step explanation:
"Product" signifies multiplication. "of" means w is being multiplied by 3.
C=pid
d=diameter
d=4
C=4pi
tada
if you want
aprox pi=3.14
C=12.56 units
X - number of 5 c stamps,
y - number of 15 c stamps,
z - number of 25 c stamps.
The system:
x + y + z = 160
y = 3 x
0.05 x + 0.15 y + 0.25 z = 25 / * 100
-------------------------------------------------
x + y + z = 160
y = 3 x
5 x + 15 y + 25 z = 2500 / : 5
----------------------------------------
x + 3 x + z = 160
x + 3 y + 5 z = 500
-------------------------
4 x + z = 160 / * ( - 1 )
10 x + 5 z = 500 / : 5
------------------------------
- 4 x - z = - 160
+
2 x + z = 100
-------------------------
- 2 x = - 160
x = 30, y = 90
z = 160 - 120 = 40
Answer:
- 30 of 5 c stamps,
- 90 of 15 c stamps,
- 40 of 25 c stamps.
