Here it is:
The first set has (0,1) and (0,5), which assigns to the *same* x, more than one value of *y*. That's not a function. It's a curve. Think about a circle, or instance. It's NOT a function, but it's a curve.
The second one has for each *x* a single *y*
BTW, there's no problem if for *different* x there is the same *y*:
y = 5,
all x, have the same y, equal to 5. That's a function, or y = x^2, etc
So, theres this rule for all 30,60,90° triangles, one leg is x, the hypotenuse is 2x, and the longer leg is x(sqrt3), so ab is 2(43) so it is 86. im not sure why it says round to 2 decimal places. uh... if so, 86.00. so... that part confused me.

Answer:
144°
Step-by-step explanation:
step 1
Find the measure of the central angle of the regular pentagon
Divide 360 degrees by 5 (the number of sides)
Let
c----> the center of the pentagon
we know that
m∠ECA=72°
m∠ACB=72°
therefore
m∠ECB=m∠ECA+m∠ACB
substitute the values
m∠ECB=72°+72°=144°
The measure of angle ECB is equal to the degrees that the pentagon rotate
Answer: The probability is 51.28%
Step-by-step explanation:
We know that out of 100% of the drivers, an 82% where stoped.
of these 84% stoped, 34% receive a blood test and 24% receive both tests, so a total of 58% received at least one test.
then, out of the 100% of the drivers, the ones that received at least a test are:
0.84*0.58 = 0.4872
So a 48.72% of the drivers received at least one test, this means that if one random driver is selected, the probability that the driver did not receive either test is 100% - 48.72% = 51.28%
