Answer:
k=5
Step-by-step explanation:
0.96-1 = -1/k^2
-1/-0.04 = k^2
25=k^2
k=√25
k=5
Answer:
28.27
Step-by-step explanation:
first you have to stablish the formula for the area of the circle, which is A=pi×radius square. Then, you have to substitute the variables and solve. the formula with the numbers plugged in would be A=3.14×3 square. Finally, solve by multiplying 3×3=9, so the formula would be 9×3.14, when multiplyed, your answer would be 28.27 if you round it.
Have a look at the first elements of each point: {3, 0, 1, -2, 2}. Since these are all different, no one x value has more than one y-value associated with it, and thus (3,-2)(0,1)(1,0)(-2,-1)(2,-1) is a function.
Answer:
Hey look you just multiply 9 with one and 4 with one then you get 9/2+4/2=13/2
