Answer:
a^2+2ab+b^2
Step-by-step explanation:
FOIL method is First variables Outer variables Inner variables Last variables
(a+b)^2 rewritten is (a+b)(a+b)
F - a*a
O - a*b
I - a*b
L - b*b
a*a+a*b+a*b+b*b
simplify
a^2+2ab+b^2
The answer is c 400 because 10 times 5 is 50 time 8 equall 400
Step-by-step explanation:
The angular velocity is defined by the position angle over time.
Get first the position angle of the pendulum which has the formula of s = rθ where s = arc length, r = radius (or length of the pendulum's string), and θ = position angle. Getting θ, we have <span>θ = s/r = 14.13 ft / 6 ft = 2.355 rad
Thus, the angular velocity is </span>θ/t where t = time; so 2.355 rad / 3 sec = 0.785 rad/sec
Hope this helps.
For 61 you can change it to √25/√49. √25=5 and √49=7 so it would simplify to 5/7.
Answer: Down
Step-by-step explanation:
We know that the graph of y
=
x
4 has both arms pointing up.
Now, since the leading coefficient of f
(
x
) is negative, both arms are pointing down. Thus the right side is pointing down.
