Answer:
(x,y) -> (-y,x), second option.
Step-by-step explanation:
Rotation of 90 degrees about the origin:
The rule for a rotation of a point (x,y) 90 degrees about the origin is given by:
(x,y) -> (-y,x)
This is that the question asks, and so, this is the answer, which is the second option.
Answer:
27°
Step-by-step explanation:
XWY and VWY are supplementary
∴ XWY + VWY = 180°
∴ XWY = 180° - VWY
XYW and ZYW are supplementary
∴ XYW + ZYW = 180°
∴ XYW = 180° - ZYW
ΔXWY is a right triangle at X
∴ XWY + XYW = 90°
∴ 180° - VWY + 180° - ZYW = 90°
∴ 180° - 6x + 180° - 4x = 90°
∴ 360° - 10x = 90°
∴ 10x = 270°
∴ x = 27°
Answer:
81x^4
Step-by-step explanation:
Apply the product rule to 3x
3^4x^4
Raise 3 to the power of 4
81x^4

Answer:
-6x^6y^5
Step-by-step explanation:
you have to find p such that
(-3
y)(p) = 18
So just divide to find p
p = 
= -6
Answer:
Step-by-step explanation:
<u>Perimeter of garden A is
</u>
- P = 2(w + l) = 2( 2x - 3 + 5(2x - 3)) = 24x - 36
<u>Perimeter of garden B is
</u>
-
5x + 5 + 4x + 2 + 8x - 8 = 17x - 1
<u>Sum of perimeters:</u>
- 24x - 36 + 17x - 1 = 41x - 37
The statement 2 is FALSE as number we got is different from the one in the statement
