it would probably be easier to turn a fraction into a decimal and then multiply
Step-by-step explanation:
Answer:
(-1-√33)/2, (-1+√33)/2
Step-by-step explanation:
If one of them is x, then it satisfies ...
x + -8/x = -1
x^2 -8 = -x . . . . . multiply by x
x^2 +x = 8 . . . . . add x+8
x^2 +x + 1/4 = 8+1/4 . . . . complete the square
(x +1/2)^2 = 33/4
x + 1/2 = ±(1/2)√33 . . . . . . take the square root
x = (-1/2)(1 ± √33) . . . . . . . subtract 1/2
The numbers are approximately ...
-3.37228, 2.37228
Answer:
45.95 pounds is the weight of the astronaut 4050 miles above the Earth.
Step-by-step explanation:
The gravitational force F ∝
F =
where r = Distance of the object from the center of the earth
and k = proportionality constant
For the astronaut weight = 186 pounds
186 = [ where radius of the Earth = 4000 miles]
k =
=
If the object is 4050 miles above the Earth then the weight of the object will be F =
F =
F =
=
= 45.94 pounds
Therefore, 45.95 pounds is the weight of the astronaut 4050 miles above the Earth.
Answer:
it is
Step-by-step explanation:
-35 = 7(10-3y)
-35 = 70 - 21y
21y = 105
y = 5
