Answer:
Step-by-step explanation:
Distribute the 4:
4d- 20-6= 16- 2d-d
Combine like terms:
4d-26=16-3d
Add 3d to 4d:
7d-26=16
Add 26 to 16:
7d=42
Divide both sides by 7:
d=6
Answer:
33
Step-by-step explanation:
You find the area of each triangle and that is (4*3)/2 which is equal to 6 but because all four sides are the same size you would multiply 6 by 4 so 6*4=24 you must also find the area of the bottom and that would be 3*3= 9 then you'd add them together 24+9=33 i hope that this helps!
Under the assumption of <em>uniform</em> motion, the traveller will travel a distance of 20 feet before slowing down the vehicle to less than 40 miles per second.
<h3>How to calculate the distance taken by traveler before braking</h3>
According to this question, the vehicle travels at <em>constant</em> velocity before the traveler hit the brakes. The distance <em>traveled</em> (s), in feet, is equal to the product of velocity (v), in feet per second, and time (t), in seconds:
s = v · t (1)
If we know that v = 40 ft/s and t = 0.5 s, then the traveled distance of the vehicle is:
s = (40 ft/s) · (0.5 s)
s = 20 ft
Under the assumption of <em>uniform</em> motion, the traveller will travel a distance of 20 feet before slowing down the vehicle to less than 40 miles per second.

Using quadratic function concepts, it is found that the minimum initial velocity that must be imparted to the ball is of 10.754 m/s.
<h3>What is the equation of motion?</h3>
The equation of motion of an object thrown upwards, considering the effect of the gravity, is given by:
In which:
- v(0) is the initial velocity.
- s(0) is the initial height.
<h3>What is the maximum height obtained?</h3>
The maximum height obtained is the output of the vertex, which is given by:
In this problem:
- The initial height is of 1 m, hence
.
- A height of 9.8 m is reached when
, hence:
The minimum initial velocity that must be imparted to the ball is of 10.754 m/s.
