Answer:
We have the magnitude, M, and the angle A.
(The angle is always measured from the +x-axis)
Then we have that:
x = M*cos(A)
y = M*sin(A)
in this case:
M = 9m
A = -80°
x = 9m*cos(-80°) = 1.562
y = 9m*sin(-80) = -8.86m
Now, the component parallel to the x axis is:
x = 9m*cos(-80°) = 1.562 m
And the slope of something parallel to the x-axis is always zero, as this is a constant line.
1) you could rotate 360 degrees about the center (0,-2)
2) you could reflect over the x axis, then over the y axis, then over the x axis, and then over the y axis, and you're back where you started those are just some choices
Answer:
28.
Step-by-step explanation:
9x^2 + 2 = 10x
9x^2 - 10x + 2 = 0
The discriminant is b^2 - 4ac.
In this case, a = 9, b = -10, and c = 2.
(-10)^2 - 4 * 9 * 2
= 100 - 36 * 2
= 100 - 72
= 28.
Since the discriminant is positive, there are two real solutions to the function.
Hope this helps!
Answer:
Step-by-step explanation:
Given that a county park system rates its 20 golf courses in increasing
order of difficulty as bronze, silver, or gold.There are only two gold courses and twice as many bronze as silver courses.
Hence we get there are 2 gold, 12 bronze and 6 silver courses.
A) If a golfer decides to play a round at a silver or gold
= He can select any one of gold or silver
= (2+6)C1 = 8 ways
B) f a golfer decides to play one round per week for 3 weeks,first on a bronze course,then silver,then gold,
=Here no of ways = 2x12x6 = 144
(Because he can play any one of two gold, any one of 12 bronze...)
(Assuming every week all games are available)
