the captain of a freighter 6 km from the nearer of two unloading docks on the shore finds that the angle between the lines of sight to the two docks is 35 degrees. if the docks are 10 km apart, how fa
find solutions in the interval [0, 2pi)
cos 2x + cos x = 0-I am interpreting this problem as:
cos(2*x) + cos(x) = 0
cos(2x) = cos^2(x) - sin^2(x) is a basic trig identity.Now we have:
(Equation 1)
Consider the numbers and each variable separately.
numbers: 12/16 divide each part by 4 = 3/4
variable f: f^6 and no denominator so it would be kept as it is
g: g/g² divide both parts by g = 1/g
Put
Yeah I need to know the square root of 16, someone please help me this is urgent.-That is a TERRIBLE thing to say! Many people died during 9/11 and for you to go and joke about that is wrong. Also, ar
Chester the dog has a chain that has a range of 100 feeth from his doghouse. Chester pulls on the chain and walks 80 feet due south. From that point he walks due west and stops at the maximum range of
If you look for the equivalent values, in this case the bottom number you can find what it has been multiplied/divided by.
Here we have 30 -> 5 which means its been divided by 6
Do the same to the ot
lim(x→+∞)=(√(x )+1)/(3+x))
Thank you so much.-lim(x→+∞)=(√(x )+1)/(3+x))
Dividing the numerator and denominator with x
=> limit
= lim(x→+∞)=(1/√(x ) + 1/x)/(3/x + 1))
= 0/1
= 0.-The 1/(3+x) is going t
2. come up with the equation of a line that is perpendicular to
y=-4/3x+9 and passes through (6,1)-Find the gradient of the perpendicular line:
m = - 4 / 3
mm˪ = -1
m˪ = -1 / m
m˪ = 3 / 4
Plug the i
The answer would be zero. One possible conceptual way to think about it is to say, multiplying 2 * 100 is like having 2 groups of 100 cookies on the table. Multiplying 1 * 100 is like having 1 group o
a coin is tossed 4 times what is the probability of getting tails four times in a row? I dont understand how to get the answer.-The probability each time of getting tails ONCE is 1/2. Everytime we wan
How do I prove that 32^2x+1 = 8^3x-2
hint: If x^a = x^b, then a=b
I have to find some way so that I can set (2x+1) equal to (3x-2) ...I think...Please help!!!-You dont really prove it, you just need
Ok so I have to find the area of a regular(congruental sided) decagon and I know that the perimeter is 240 and each side is 24. I looked online and found out that the formula is 1/2(ap), so I guess th
