Answer:
The solution to the system of linear equations is (1,9).
Step-by-step explanation:
The given system of linear equations
... (1)
.... (2)
Subtract equation (2) from equation (1) to eliminate y.
On combining like terms, we get
Add 8 on both sides.
Divide both sides by 8.
The value of x is 1.
Substitute x=1 in equation (1).
The value of y is 9.
Therefore the solution to the system of linear equations is (1,9).
Answer:
The power of horse is: P = 72000 W
Step-by-step explanation:
Given
- F = 1800 N
- v = 40.0 m/s
To determine
P = ?
Using the formula
The ⋅ in the formula represents a scalar product, defined by:
The angle Ф is zero because F and v are are parallel.
Thus the cosine is 1.
Therefore,
P = (1800) (40.0)
P = 72000 W
Hence, the power of horse is: P = 72000 W
Answer:
8.12
Step-by-step explanation:
We obtain the distance between x and y
d = sqrt[(x2 - x1)² + (y2 - y1)²]
d = sqrt[(1 - 2)² + (2 - 6)²]
d = sqrt[1 + 16)
d = sqrt(17)
d² = 17
From Pythagoras rule;
Hypotenus = sqrt(Adjacent² + opposite²)
Hence,
Hypotenus = sqrt(17 + 7²)
Hypotenus = sqrt(17+ 49)
Hypotenus = sqrt(66)
Hypotenus = 8.124
Hypotenus = 8.12
