I think its 28 square feet. Im not 100% sure
Answer:
Step-by-step explanation:
The dog's route and final facing direction are shown in the attached diagram.
<h3>Turns</h3>
The sequence of facing directions for right turns is ...
{N, E, S, W, N}
The sequence of facing directions for left turns is the reverse:
{N, W, S, E, N}
In total, the dog made 3 right turns and 2 left turns. The net change in facing direction is 3-2 = 1 right turn. The dog's initial facing direction is north, so its final facing direction is east, one right turn from north.
<h3>Distance</h3>
The distances traveled are ...
N 4, E 1, S 5, E 2, N 5.
The net change in position is north (4-5+5) = 4 miles, and east (1 +2) = 3 miles. The distance between the final point and the initial point is the hypotenuse of a right triangle with legs 4 miles and 3 miles. The Pythagorean theorem tells us that distance is ...
c² = a² +b²
c = √(a² +b²) = √(4² +3²) = √25 = 5
The smallest distance between the dog's final and initial points is 5 miles.
The topics you should learn are equating denominators and fractions. This is summing up simple fractions.
So we have to make denominators' numbers the same in order to sum up them all (we can sum fractions if the denominators are the same) , and we did it by cross product (that thing on the picture)
Equating by lcm (least common multiple) is the easiest way, because you might see bigger numbers on other questions, and cross product will bring much bigger numbers, so this technic might confuse you.
By the way lcm of 4 and 5 is already 20

Answer:
3 m/s^2
Step-by-step explanation:
helpful formula below
a= (v - u)/t ....where v is the final velocity, u is the initial velocity, t is time elapsed
acceleration = (30 - 0)/10
= 3 m/s^2
