Answer:
13
Step-by-step explanation:
It is a parallelogram so the opposite angles are the same.
All angles sum to 360 degrees.
This means that the adjacent angles sum to 180 degrees.
4a + 11 + 9a = 180 = 13a + 11
13a = 169
a=13
Answer:
Step-by-step explanation:
put them both in exponential form and then since they are both base 6, you can add the exponents.
Calibration curves <span>absorbance versus concentration may deviate from a straight line when A<0.1 and when A>1 maybe because at these values the substances react to light differently which will cause it to not follow a linear graph. Hope this helps. Have a nice day.</span>
The a in front of Sin is the amplitude and the period is 2pi/k.
To get a period of 3pi, set up an equation. 3pi = 2pi/k and solve for k.
3pi = 2pi/k
Multiply k on both sides.
k * 3pi = 2pi
Divide both sides by 3pi
k = 2pi/3pi; k = 2/3
y = 9Sin(2/3)x
Answer:
B
Step-by-step explanation:
if its less than 1, the side lengths are smaller than the original.
