Answer:
A. y = 2x
C. $12
Step-by-step explanation:
Using the equation we just made we can find how much it costs to ride the subway 6 times by plugging it in
y= 2•6
y= $12
hope this helps chu :3
Answer:
Below.
Step-by-step explanation:
37+8= 45
45-8=37
so 45.
Divide:
a.) 5,600/20 = 280
b.) 475/25 = 19
c.) 650/50 = 13
d.) 7,280/80 = 91
Shortcut method on the left side of the image that i use:
The slope of a line is (change in y)/(change in x), so we can plug it in to here to get (11/5-6)/(3/16-1/10). It doesn't matter which y value you subtract from, but just make sure that the number you subtract from in both the numerator and denominator is from the same point!
Answer:
4.097 s
Step-by-step explanation:
The formula for ballistic motion usually used is ...
h(t) = -4.9t² +v₀t +s₀
where v₀ and s₀ are the initial vertical velocity and height, respectively. Here, we have v₀ = (35 m/s)sin(35°) and s₀ = 0. We want to solve for h(t) = 0.
0 = -4.9t² +35sin(35°)t = t(-4.9t +35sin(35°))
This is true for t=0 and for ...
t = 35sin(35°)/4.9 ≈ 4.09697 . . . seconds
It will take about 4.097 seconds for the projectile to reach the ground.

Desmos has a setting option for angles in degrees. That is what we used here.
