Answer:
21.7%
Step-by-step explanation:
(25,550-19,990) / 25,550 = 5,560/25,550 = 0.217612524462 or 21.7% increase
Answer: 2.2x * 10^3
You would have to move the decimal place 3 times for 2.2x to get 2,200x, thus you get 10^3.
Hope this helps!
Answer:
y = |x + 2|
Step-by-step explanation:
given the straight shape, it must be a linear function, but the "bend" in it indicates that an absolute value is being used.
So to start we can say: y = |x|
But that's not sufficient, as it would show that bend being at 0, 0. Instead, we need to translate it two units to the left, giving us:
y = |x + 2|
Answer:
4. 
°
Step-by-step explanation:
Given:
The tangent of the angle is given as:
Since the angle is negative, it means that it is measured in the clockwise direction as angles measured in clockwise direction are negative and that measured in counter clockwise directions are positive.
-212° when measured from counter clockwise direction will be equal to:
Therefore, = 
Now, we have the identity for tan as:
Here, 
Therefore,
Hence, = = °
Answer:
m∠ TRS = 60° , m∠ SRW = 120°
Step-by-step explanation:
First, find x
∠TRS = ∠VRW (vertically opposite angles are equal)
x + 40° = 3x
x - 3x = -40
-2x = -40
x = -40/-2
x = 20
m∠ TRS = 60° [x + 40 = 20+40 = 60]
m∠ SRW + m∠ TRS = 180° (linear pair)
m∠ SRW + 60° = 180°
m∠ SRW = 180° - 60°
m∠ SRW = 120°
hope this helps you
