Answer:
it b
Step-by-step explanation:
Solve equation [1] for the variable x [1] x = 3y - 1
// Plug this in for variable x in equation [2] [2] 8y - 2•(3y-1) = 4
[2] 2y = 2
// Solve equation [2] for the variable y [2] 2y = 2
[2] y = 1
// By now we know this much : y = 1
x = 3y-1// Use the y value to solve for x x = 3(1)-1 = 2
(6*10^20)-(29*10^16)=2068.97
my best guesstimate is 2000 times larger <span />
Answer:
1057.89 feet
Step-by-step explanation:
Trig time! Start with a diagram and listing out your trig functions, either mentally or on paper. SOH CAH TOA
The best trig function for this problem is likely tan:
tan84.6 = height / 100
100 * tan 84.6 = height
height = 1057.89 feet
I think the answer is C) 3.2 units i am sorry if i am wrong
Answer:
Both X and Y are equal to 15 multiply by the square root of 2.....(i just do not know how to type the symbol on my keyboard)
Step-by-step explanation:
So for X:
X=30 sin 45
=15 multiply by the square root of 2
For Y:
Y=30 cos 45
=15 multiply by the square root of 2
But you could also use theorem of Pythagoras
