Answer:
82
Step-by-step explanation:
The shape formed by the three lines is a triangle. That would mean all of the angles must add up to 180 degrees.
53+45=98
180-98=82
Answer:
Step-by-step explanation:
Key features
when t = 0
the initial height is 143/3 = 47⅔ ft
initial velocity is -310/3 = -103⅓ ft/s (downward)
initial acceleration is 2(64) = 128 ft/s² (upward)
I would not like to ride this roller coaster!
that's about four times the acceleration of gravity, and it only increases as the car gets to the bottom of the curve at t = 1 s
For part 3
I'm not sure what they mean by "not realistic"
while the initial acceleration is high. the acceleration at t = 1 is zero except that in 'reality' the car would have to be going through a curve to change direction from down to up. That would create very high centripetal acceleration and therefore centripetal forces.
Answer:
73.6
Step-by-step explanation:
this is an addition question so we're going to answer it with an equation let's put 24.6 + 49 =73.6
Answer:
So, we purchased 9 songs and 4 games for 20.1$.
So, we purchased 10 songs and 6 games for 25.5$.
So, we purchased 10 songs and 10 games for 33.9$.
Step-by-step explanation:
We have receive a $35 gift certificate from an online retailer that sells digital music and games. Each song costs $1.29 and each game costs $2.10.
First case:
So, we purchased 9 songs and 4 games for 20.1$. We have 13 items for 20.1$.
Second case:
So, we purchased 10 songs and 6 games for 25.5$. We have 16 items for 25.5$.
Third case:
So, we purchased 10 songs and 10 games for 33.9$. We have 20 items for 33.9$.
