Answer:
The proposed 1600 meters runway length is not long enough
Step-by-step explanation:
The given parameters are;
The amount by which a plane can accelerate = 3.3 m/s²
The time it takes for a plane to lift off the ground = 35 seconds
The length of the runway on the blueprint = 1,600 meters
Therefore, from the equation of motion for distance traveled, s, acceleration, a, and time taken, t, we have;
s = u·t + 1/2·a·t²
Where;
u = The initial velocity
t = 35 seconds
a = 3.3 m/s²
Given that all planes will start motion from rest, we have;
u = 0 m/s
Therefore;
s = 0 × 35 + 1/2 × 3.3 × 35² = 2021.25 meters
Which indicates that the length of the runway a plane would need for take off should be at least 2021.25 meters long, therefore, the blueprint's 1600 meters runway length is not long enough.
For the question in the photo:
y = 2.50x + 7.50
Domains:
0, 2, 3, 4, 5, 6, 7, 8, 9, 10
As you can’t ride 0.2 or 0.7 of a ride, for example, and you only have time for ten rides. Plus you have enough money to ride ten rides
For the drama club one:
C = 21t + 40
Is the correct answer as 40 is a set value and is not influenced by the amount of club members there are, x is the amount per shirt, and C is the cost
Answer:
1120
Step-by-step explanation: All you have to do is multiply 4x4x5x14 equals 1120
Answer:
(y − 9) (y − 2)
Step-by-step explanation:
Factor y^2 − 11y + 18 using the AC method.
(y − 9) (y − 2)
The “AC” method or factoring by grouping is a technique used to factor trinomials. A trinomial is a mathematical expression that consists of three terms.
