Answer:
The original point (x , y) —> the point rotated (-y , x)
Step-by-step explanation:
Answer: find the solution in the explanation
Step-by-step explanation:
Let's use resolution of forces by resolving into x - component and y- component.
X - component.
Sum of forces = F1 - F3 - F4cos 15
Sum of forces = 0
5 - 5 - 0.97F4 = 0
- 0.97 F4 = 0
F4 = 0
Y - component
Sum of forces = F2 + F4 sin 15
Sum of forces = 0
5 + 0.26F4 = 0
0.26 F4 = -5
F4 = -5/0.26
F4 = -19.23 N
Simulating F4 back into the equation
Sum of forces = F1 - F3 - F4cos 15
- F4cos Ø = 0
- (-19.23) cos Ø = 0
Cos Ø = 0
Ø = 1
Does the angle formed approximate 15 degrees ? NO
Answer:
3,4,5
Step-by-step explanation:
Here, we want to select the set that could work and the sides of a right angled triangle
the correct answer is 3,4,5
These set are called a Pythagorean triple
This is because adding the square of the two smaller number will give the square of the largest number
What we are saying here is that by adding the square of 3 and 4, we get the square of 5 which illustrates that Pythagoras theorem works for the set
Option 3: 
is the right answer
Step-by-step explanation:
Given expression is:
![(\sqrt{2})(\sqrt[3]{2} )](https://tex.z-dn.net/?f=%28%5Csqrt%7B2%7D%29%28%5Csqrt%5B3%5D%7B2%7D%20%29)
In order to simplify the expression we have to convert the radicals in exponents
As he base is same, the powers can be added
Hence,
Option 3: is the right answer
