Answer:
16.3 N
Step-by-step explanation:
subtract if the forces are opposite
n, n+1 - two consecutive integers
n(n + 1) = 50 <em>use distributive property</em>
n² + n = 50 <em>subtract 50 from both sides</em>
n² + n - 50 = 0
-----------------------------------------------------
ax² + bx + c =0
if b² - 4ac > 0 then we have two solutions:
[-b - √(b² - 4ac)]/2a and [-b - √(b² + 4ac)]/2a
if b² - 4ac = 0 then we have one solution -b/2a
if b² - 4ac < 0 then no real solution
----------------------------------------------------------
n² + n - 50 = 0
a = 1, b = 1, c = -50
b² - 4ac = 1² - 4(1)(-50) = 1 + 200 = 201 > 0 → two solutions
√(b² - 4ac) = √(201) - it's the irrational number
Answer: There are no two consecutive integers whose product is 50.
Answer:
Neither
Step-by-step explanation:
They do not form a 90° angle(so it's not perpendicular)
And they touch(so it's not a parallel)
Y should equal -7/2 or -3.5
Answer:
t2=8/5
Step-by-step explanation:
using this formula
t1/s1 =t2/s2
4/5=t2/2
cross multiply
5t2=8
t2=8/5
