Answer:
The resultant vector is . The resultant displacement is 1 miles.
Step-by-step explanation:
It is given that Minossoo is training for cross country in the fall. He ran 5 miles east. Then he turned around and ran 4 miles west.
Let he start from point A, then ran 5 miles east and reach to point B. After that he turned around and ran 4 miles west to reach point C.
His initial direction is east, then he turned and run along the west direction. The resultant vector is
The resultant displacement
Therefore resultant vector is . The resultant displacement is 1 miles.
Product factor is an expression in where you multiply the same value digit SEVERAL times
Exponent is the expression in where you convert product factor expression into a more brief (shorter) expression
For example of product factor:
-> 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3
As you can see, 3 is multiplied many times, that makes it more extended.
Now, let’s make this product factor shorter using exponent.
-> since 3 is multiplied 3 times the exponent expression is:
-> 3 3 in where 3 is the base and the other 3 is called exponent.
Answer:
The window should be positioned 4 1/8 feet far from each edge of the wall.
Step-by-step explanation:
Since a construction crew is placing a square in a wall for a new window, which is 3 1/8 feet wide, while the wall has a length of 11 3/8 feet, and the crew wants to position the window at the center of the wall, to determine how far from each edge of the wall should the window be positioned, the following calculation must be performed:
1/8 = 0.125
3/8 = 0.375
(11,375 - 3,125) / 2 = X
8.25 / 2 = X
4.125 = X
Therefore, the window should be positioned 4 1/8 feet far from each edge of the wall.
Answer:
15.75
Step-by-step explanation:
A = (B + b)×h/2
= (4 + 5)×3.5/2
= 9×3.5/2
= 4.5×3.5
= 15.75
Answer:
first option
(8, -1)
Step-by-step explanation:
We have the following system of linear equations
To solve the system multiply the first equation by -5 and then add it to the second equation.
-----------------
substitute in any of the two equations and then solve for x
The answer is the first option
(8, -1)
