Answer:
A real Even integers
Step-by-step explanation:
Step-by-step explanation:
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
Mars radius = 3,393 km
Mars Mass = 6.42 x 10^23 kg
Earth Radius = <span>6,371</span><span> km
Earth Mass = </span><span>5.97237×10<span>^24kg
Gravity is directly proportional to mass and
Gravity is inversely proportional to the square of the distance.
So, we can come up with this equation:
Force = Mass / radius^2
Force Earth = 5.97237 x 10^24 / 6,371^2
Force = </span></span><span>1.471 x 10^17
Force Mars = 6.42 x 10^23 / 3,393^2
Force = 5.577 x 10^16
Earth's gravity vs Mars' Gravity = </span>1.471 x 10^17 / <span><span>5.577 x 10^16
</span>= 2.64
Earth has 2.64 times the gravitational attraction that Mars has.
</span>So, you would weigh 834 / 2.64 =
316 Newtons on Mars.
Answer:
0
Step-by-step explanation:
Substitute x = - 3 into the expression
x² + 4x + 3
= (- 3)² + 4(- 3) + 3
= 9 - 12 + 3
= 0
