One is 3pi/2 - 2pi = -pi/2
also -7pi/2
Answer:
Perpendicular lines have slope that are negative reciprocals.
The slope of the perpendicular line is M = -1/3.
Step-by-step explanation:
(4,-1) --> X = 4, Y = -1, M = -1/3
y = Mx + b
-1 = (-1/3)*4 + b
-1 = (-4/3) + b
-3/3 = (-4/3) + b
-3 = -4 + 3b
1 = 3b
b = 1/3
y = (-1/3)X + 1/3
Answer: 48 sq. cm
Step-by-step explanation:
The area of the similar shapes is similar.
We use scalar factor to get the area of the bigger or the smaller figure by using the area of the given figure.
In the given figure , Area of the small pentagon = 32 sq. cm
Scale factor for the bigger pentagon = 1.5
Then , the area of the bigger pentagon would be = (Scale factor) x (Area of the small pentagon)
= 1.5 x (32 sq. cm)
= 48 sq. cm
Hence, the area of the larger pentagon = 48 sq. cm
The coefficients in the equation (-x)(3y)(-2x) are the constants -1, 3, and -2.
In order to simplify and determine only one coefficient <span>we should multiply all three constants together to get only one numerical constant .
</span><span>The commutative law</span> says hat you can rearrange a multiplication any way you want. so, (-1)*3*(-2)=(-3)*(-2)=6
The equation can be also simplified written as:
6x^2y
None of the option is the solution.
