Answer:
4
Step-by-step explanation:
if you put it in y=mx+b form you would get y=4x-8=72
Answer:
(2,-2)
Step-by-step explanation:
The solution to a system of equations like these, is where the two lines intersect. In this case, I believe, it would be at point (2,-2). Although, it is a little hard to pinpoint without the labeled number lines.
Hope this helps! Best of luck!
The only other possible meaning I can see is that a2 + b2 means a^2 + b^2. In the case that is a formula that cannot be simplified further, although it could be written as (a + b)^2 - 2ab or (a - b)^2 + 2ab. ... Originally Answered: What is the formula of a2+b2?
Answer:
0.45 second
Step-by-step explanation:
The number of seconds it takes a dropped object to fall d feet on Earth is given as:
E(d)=0.25√d
the number of seconds it takes a dropped object to fall d feet on the sun is given as:
S(d)=0.2⋅E(d)
Therefore
S(d)=0.2 × 0.25√d = 0.05√d
Given that it take a dropped object to fall 80 feet on the sun (i.e d = 80 feet), to calculate the time in seconds we use:
S(d) = 0.05√d
S(d) = 0.05 × √80 = 0.05 × 8.944 ≈ 0.45 s
It takes 0.45 second for a dropped object to fall 80 feet on the sun
