Answer:
15pi (irrational), -2 (rational), -77.33 (rational), - (rational), -39.93 (irrational)
Step-by-step explanation:
15pi - irrational because remember pi is irrational.
-2 square root 7 - rational because it gives a terminating decimal.
-77.33 - rational, as it gives a terminating decimal.
-39.93 - irrational as the line above it, means it never ends.
Answer:
x^2-4x+y^2+6y-108=0
Step-by-step explanation:
You can determine this by finding zeros of quadratic function,
.
Which eliminates first and third option.
Now we have up and down parabolas left.
If we factor we find that the coefficient before determines how it is turned, since its positive its an upward turned parabola hence the answer is the last graph.
Hope this helps.
Put the values where the variables are, then do the arithmetic.
8 - 8/2 +7² = 8 - 4 + 49 = 53
2/5 will be shaded in the original how I got it s that you make a rectangle and make fifths inside and shade in 3/5 of that and see what matches up on the top.
