Answer:
8% increase
Step-by-step explanation:
The length after the increase:
30 x 1.1 = 33cm
The width after the increase:
20 x 1.05 = 21cm
New perimeter:
2(33 + 21) = 108 cm^2
Old perimeter:
2(30 + 20) = 100 cm^2
Percentage increase of area:
108 / 100 = 1.08 = 8% increase
Answer:
B. (5, ∞)
Step-by-step explanation:
The correct answer choice is marked.
__
The absolute value function increases to the right of its vertex. Here, the vertex has been moved to (x, y) = (5, 2). This means the function is increasing for 5 < x.
In interval notation, the domain of increase is (5, ∞).
Answer:
Step-by-step explanation:
So first you got to simlipy both sides of the equation.Like this:
10x-3x+2=6x+6
7x+2=6x+6
Then you have to move the variables to one side and the other nums to the other side:
7x-6x = 6 -2
Then you have to simplify.
x = 4

Step-by-step explanation:
For an angle of 180°:
- hypotenuse = 1
- Adjacent side = 1
- Opposite side = 0
Then, sin Ф = 
sin 180° = 
sin 180° = 0
