you would get paid more at the second job if you worked for 5 hours
Answer:
y = 1609 ft
Step-by-step explanation:
g is equal to 9,8 m/s² or 32,18 ft/s²
According to g = 32,18 ft/s²
In the first second as y = -1/2 g*t²
y = 1/2 32,18*(1)² ⇒ y = 16,9 ft we dismiss the sign we know the object is falling down. Is enough for the purpose of this question
The second one
y = 1/2* (32,18)* (2)²
y = 32,18*2 ⇒ y = 64,36 ft
third second
y = 1/2*32,18*(3)² ⇒ y = 144,81 ft
And in the tenth second
y =( 1/2)* 32,18 * (10)² ⇒ y = 1609 ft
Answer: 2

Answer:
its 7
Step-by-step explanation:
Answer:
y=4/3+19/3
Step-by-step explanation:
When it asks for perpendicular it means your focusing on the slope.
Perpendicular means opposite of the current slope, so flip it and change the sign (-3/4 changes to 4/3). Next you will use the equation (y-y1)=m(x-x1)
y1=the y value given
x1=the x value given
m=your slope
(y-1)=4/3(x+4) Since the x point is minus a negative we get to change the sign to a positive. Next distribute the 4/3 to each term in the parenthesis.
y-1=4/3(x)+4/3(4)
y-1=4/3x+16/3 Now we add the one to both sides.
+1 +1 The one isn't in teh correct format to just add so first imagine it as 1/1. Now to get the bottom to have a 3 like in 16/3 we just multiply the top and bottom by 3.
Now we can add this to the 16/3
We can now put this back into our equation.
y=4/3+19/3
