It's more easy, from the first question you already know the equations, you want to find S, so you have to find those two equations intersection, which means:
1/2x-1=-2x+9
1/2x+2x=9+1
2.5x=10
x=4
then put x=4 in to any of the equation: y=-2x+9. x=4
y=-2x4+9
y=-8+9
y=1
so the coordinate of S is (4,1)
Answer:
Force, F = 68.93 pounds
Step-by-step explanation:
Given that,
Mass of the astronaut, m = 80.70 kg
Acceleration due to gravity on Mars, ![a=3.8\ m/s^2](https://tex.z-dn.net/?f=a%3D3.8%5C%20m%2Fs%5E2)
The force acting on him is given by using second law of motion as :
![F=m\times a](https://tex.z-dn.net/?f=F%3Dm%5Ctimes%20a)
![F=80.70\ kg\times 3.8\ m/s^2](https://tex.z-dn.net/?f=F%3D80.70%5C%20kg%5Ctimes%203.8%5C%20m%2Fs%5E2)
F = 306.66 N
Since, 1 newton = 0.224 pound
F = 306.66 N = 68.93 pounds
So, 68.93 pounds force she exerts on the martian surface. Hence, this is the required solution.
Answer:
1/64
Step-by-step explanation:
![(\frac{1}{4} )^{3} =\frac{1^{3}}{4^{3}} =\frac{1}{64 }](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B4%7D%20%29%5E%7B3%7D%20%3D%5Cfrac%7B1%5E%7B3%7D%7D%7B4%5E%7B3%7D%7D%20%3D%5Cfrac%7B1%7D%7B64%20%7D)
Answer:
88 > 9
59 > 41
157 < 174
18 < 129
Step-by-step explanation:
< means Less Than
> means Greater Than
= means Equal to
Now,
88 > 9
59 > 41
157 < 174
18 < 129

Answer: 2.5625
Step-by-step explanation:
A credits: (4x 3) = 12
B credits: (3x3x2) = 18
C credits: (2x4) = 8
D credits: (1x3) =3
The total credit points are 41
The total credits the student took to earn the points was 3 + 2 + 2 + 2 + 4 + 3= 16.
To figure out GPA: credit points/credits= 41/16 = 2.5625
