Answer:
27 N
Step-by-step explanation:
Since force varies directly with acceleration, we can introduce a constant, k, and write 
When force is 15, acceleration is 5, so plug it into the equation and solve for k:
Now, to find force, we use a = 9 and k = 3, so
The force is 27 N
D^2 = (x2 - x1)^2 + (y2 - y1)^2
d^2 = (8 - 4)^2 + (k - 2)^2
d = 5 so
5^2 = 4^2 + k^2 - 4k + 4
25 = 16 + k^2 - 4k + 4
25 = 20 + k^2 - 4k
0 = k^2 - 4k - 5
0 = (k - 5)(k + 1)
k has 2 answers
k - 5 = 0
k = 5
k + 1 = 0
k = - 1
The two answers are
(8, 5) and (8, -1) <<<< answer
Answer:
2/3 in 3/4 of an hour. that would mean u an extra 1/4 of an hour would give Katie the time to finish up the project
Step-by-step explanation:
Katie, take no breaks when u can get this done in an hour. don't be lazy
Supplementary = angles add up to 180
Measure = 20 less
Labelled as x + (x - 20) = 180
Solve.
x + (x - 20) = 180
2x = 200
/2 /2
x = 100
Angle 1: Angle 2:
x - 20 x
100 - 20 100
80
Therefore the angle is 80 degrees.
Proof: 80 + 100 = 180 (supplementary)
100 - 80 = 20 (80 is less than supplement (100)
Hope I helped :))))
