Answer: The coordinates of the vertex are : (-1,-2)
Step-by-step explanation: To find the x coordinate, we use the formula:
Xv = -b/2a = -6/(2.3) = -6/6 = -1
Replacing x by -1, we write:
y = 3. (-1)^2 + 6. (-1) +1 = 3 - 6 + 1 = -2
Answer: In the hundreds place.
Step-by-step explanation:
1. You know that the first number has a 7 in its tenths place. This means that it is after the decimal point. You can write is as following:
x.7
Where x represents the other digits.
2. The second number has a 7 with a value that is 1,000 times greater than the value of the 7 in the first number, this means that you can know the place of the 7 in the second number if you multiply the first number by 1,000, or in other words, move the decimal point three places to the rigth. Therefore:
x.7*1000=7xx
3. As you can see, the 7 is in the hundred place in the second number.
Answer:
That is asking you to find the sine of (3/4) PI radians.
If you look at the attached graphic, you will see that (3/4) PI radians = 135 degrees
Going to this calculator, we see that the sine of 135 degrees is 0.70711
