Answer:
77
Step-by-step explanation:
8 and 2/5 times 18 and 1/3 is 154. Divide 154 by 2 or multiply by 1/2 and get 77
Answer:
27.32 m
Step-by-step explanation:
We are given that
Height of window from the ground=18 m
Height of rock form the ground=2 m
Speed of thrown rock=30 m/s
We have to find the horizontal distance from the window from which rock was release.
Difference between window and rock=18-2=16 m
Initial vertical velocity component=m/s
Initial horizontal velocity component=
If the rock is reached to maximum height
Then, maximum height=
Time taken by rock to reach maximum height=
Distance between window and maximum height at which rock reached=18.9731-16=2.973 m
Time to drop 2.973 m=
Time to be at 16 m=1.96775-0.77893=1.189 s
Horizontal distance=
Hence, horizontal distance of rock from the window from which rock was released=27.32 m

Answer:
): "x2" was replaced by "x^2". 4 more similar replacement(s).
Step by step solution :
Step 1 :
Step 2 :
Pulling out like terms :
2.1 Pull out like factors :
x6 - x5 + x4 - x3 + x2 - x =
x • (x5 - x4 + x3 - x2 + x - 1)
2.2 Factor x5 - x4 + x3 - x2 + x - 1
Try to factor this 6-term polynomial into (2-term) • (3-term)
Begin by splitting the 6-term into two 3-term polynomials:
-x2 + x - 1 and x5 - x4 + x3
Next simplify each 3-term polynomial by pulling out like terms:
-1 • (x2 - x + 1) and x3 • (x2 - x + 1)
Note that the two simplified polynomials have x2 - x + 1 in common
Now adding the two simplified polynomials we get
(x3 - 1) • (x2 - x + 1)
Answer:
Step-by-step explanation:
the subtraction symbol means that you will be finding the difference
6x^4-10x^4
the exponents will stay as they are because they are the same
you just have to combine the like terms 6x^4 and 10x^4
a term is separated by a symbol (in this case it is a subtraction symbol)
6x-10x=-4x
so you will just put the exponent back in place and your answer will be
-4x^4
