Answer:
none of the tables shown
Step-by-step explanation:
Inverse variation is
xy = k where k is the constant
xy = 4
in the top table
-2*2 = -4 so it cannot be the first table
In the middle table
-2 * -8 = 16 so it is not the middle table
In the bottom table
-2 *4 = -8 so it is not the bottom table
There must be a table not shown
It is a root of the polynomial if it causes the equation to equal 0.
Let's try each number.
Substituting -3 for x...
(-3)³ - 4(-3)² -11(-3) + 30
-27 - 36 + 33 + 30
0
Therefore, a. -3 is a root to our polynomial.
You could try the rest, but I won't waste time with it. None of the others are roots, and it's multiple choice which means usually just one answer.
You have to convert everything into miles and then draw the tangent line that goes from the peak of the mountain to the horizon. That can form a right triangle since tangent lines are perpendicular to the radius at the point they touch the circle. then you can solve for the horizon which is one of the legs of the right triangle. when you do everything it should end up being 174 miles. I will attach my work so you can try to decipher what to do.
I hope this helps.
Answer:
It will take him 125 mins
Step-by-step explanation:
<u>pages | 7 | 175 </u>
<u>min | 5 | x </u>
7 times 25 = 175
5 times 25 = 125
x=125
