Answer:

(4,-3)

Step-by-step explanation:

If you graph this point, then it will be in the 3rd quadrant.

A 180 degree rotation will put it in the 1st quadrant.

And the extra 90 degrees will put in in the 4th quadrant, so we know that in (x,y), x is positive, and y is negative. then if you theoretically rotate it, since you are rotating it 90 degrees, 3 times, you will have to switch the x and y, since 3 is an odd number. so the final answer is (4,-3).

Answer:

(4, -3)

Step-by-step explanation:

270° clockwise = (360-270) = 90° counterclockwise

When rotating 90° counterclockwise (x, y)----> (-y, x)

(-3, -4) ---> (-(-4)), -3) =(4, -3)

Two triangles have altitudes of equal length. if the areas of these triangles have a ratio of 3:4 then the bases of the triangle

MatroZZZ [7]

Answer:
3/4
Area of the small triangle/Area of larger triangle=3/4

Area of the small triangle/Area of larger triangle=(1/2×base of small triangle×length)/(1/2×base of larger triangle×height)
3/4=(1/2×base of small triangle×height)/(1/2×base of larger triangle×height)
Since the length of the triangle are equal the base ratio of the two triangles is the same as area ratio.

If f Subscript x(a,b)equals f Subscript y(a,b)equals0, does it follow that f has a local maximum or local minimum at (a,b)?

Anna [14]

Answer:

Step-by-step explanation:

The point must be a critical point but it could be a saddle point. If the point is a saddle point it would not be neither a maximum nor a minimum. So it must be critical but it does not follow directly that it has a local maximum or local minimum.

Therefore D. (a,b) would be a candidate, but is not necessarily a maximum or minimum. It could be a saddle.

Grovell works at Walmart. He earns $12 per hour. The store offers him a raise of 5% increase per hour.

DerKrebs [107]

Answer:

$ 12.6 / h

Step-by-step explanation:

5% of 12 = 0.05 * 12 = 0.6

Now adding it to the amount he makes, since it is a raise:

0.6 + 12 = 12.6 $ / h

Another (and faster) way to calculate it:

1.05 * 12 = 12.6
