The point (-5,-4) is rotated 90 counterclockwise .

1 answer:

5 0

(-4,5) is the correct answer because it needs to be (-y,x) meaning the original x value stays the same because we’re going backwards and the y value changes signs

How to find a slope

exis [7]

Answer:

Step-by-step explanation:

y₂₋y₁ / x₂-x₁ if you have two points you can plug them in and find the slope using this.

If it is on a graph you can look at two points and count the rise over run, for example if one point is (0, 0) and another is (2, 3) then from the first point it goes up 2 and over 3, so the slope would be 2/3

Find the surface area of the attached figure and round your answer to the nearest tenth, if necessary.

mariarad [96]

Answer:

$S.A = 246.6 in^2$

Step-by-step explanation:

The figure given above is a square pyramid, having a square base and 4 triangular faces on the sides that are of the same dimensions.

Surface area of the square pyramid is given as: $B.A + \frac{1}{2}*P*L$

Where,

B.A = Base Area of the pyramid = 9*9 = 81 in²

P = perimeter of the base = 4(9) = 36 in

L = slant height of pyramid = 9.2 in

Plug in the values into the given formula to find the surface area

$S.A = 81 + \frac{1}{2}*36*9.2$

$= 81 + 18*9.2$

$= 81 + 165.6$

$S.A = 246.6 in^2$

Answer:

6, -2

Step-by-step explanation:

basically It asks you what's x when y=2, which on the graph is 6, -2, and -5 I think. but there is no point on the -5 so we don't need to talk about that one.
