Answer= x³+4x²+16x+64
Expand the following:(x + 4 i) (x - 4 i) (x + 4)
(x - 4 i) (x + 4) = (x) (x) + (x) (4) + (-4 i) (x) + (-4 i) (4) = x^2 + 4 x - 4 i x - 16 i = -16 i + (4 - 4 i) x + x^2:
-16 i + (-4 i + 4) x + x^2 (4 i + x)
| | | | x | + | 4 i
| | x^2 | + | (4 - 4 i) x | - | 16 i
| | | | (-16 i) x | + | 64
| | (4 - 4 i) x^2 | + | (16 + 16 i) x | + | 0
x^3 | + | (4 i) x^2 | + | 0 | + | 0
x^3 | + | 4 x^2 | + | 16 x | + | 64:
Answer: x^3 + 4 x^2 + 16 x + 64
Answer:
About 4.1323 meters.
Step-by-step explanation:
We can use the following kinematic equations:
We want to determine the distance the object has dropped after falling from rest and reaching an instantenous speed of 9 m/s.
We are given that the acceleration due to gravity is 9.8 m/s².
Using this fact and the first equation, find the time for which it took the object to reach 9 m/s. Note that the initial velocity is 0 m/s since the object started from rest.
To find how far the object dropped, we can use the second equation:
In conclusion, the object would have dropped about 4.1323 meters.
Answer:
D, 2(b-1)/ab
Step-by-step explanation:
subtract 2+b/ab from 3/a
it means 3/a - 2+b/ab
lcm is ab
(3b-(2+b))/ab
(3b-2-b)/ab
(3b-b-2)/ab
(2b-2)/ab
2(b-1)/ab
Girls = x
boys = y
y = 92 - x
y = 17 + 2x
y = 92 - x
-y= -17 - 2x
0 = 75 - 3x
3x = 75
x = 25
25 girls play sports at the school
y = 92 - 25
y = 67
67 boys play sports at the school
I do not think it is equal to 17. I think it is less than. I apologize if I am wrong.
