Answer:
Step-by-step explanation:
Given
Represent point A as thus;
Required
Determine the new position of A, when rotated counterclockwise
The new position will be denoted as A'
When a point is rotated counterclockwise, we start by switching the positions of x and y as follows:
Then, y is negated to give A'
Answer:
15 x 8 = 120
Step-by-step explanation:
There are 15 tables and 8 people sit at each the number of people that would be able to go would be 120
Answer:
A
Step-by-step explanation:
u = sqrt(x)
x = u²
dx/du = 2u
dx = 2u × du
x(x+2)²/sqrt(x) . dx
u² × (u²+2)]/u × 2udu
2 × u²(u²+2).du
Answer:
Step-by-step explanation:
f(g(x) ) = 5(g(x)) +8
=5(3)+8
=15+8
=23
g( f(x) ) = 3(f(x))
=3(5x+8)
=15x +24
