Use SOHCAHTOA. sin=opposite/hypotenuse, cosine=adjacent/hypotenuse, and tangent=opposite/adjacent
The area is 100 I think because the length and height is 10 right hope this helps
Step-by-step explanation:
3 x^3-15x^2+18x 3(x^3-5x^2+6x)
Answer:
The distance A’C’ is 4.47 units
Step-by-step explanation:
Before we go on, we need to get the appropriate transformation
Mathematically, we have a 90 degrees clockwise rotation yielding the following;
(x,y) to (-y,x)
A is (-4,1)
C is (-2,5)
By transforming, we have
A’( -1,-4)
C’ (-5,-2)
To get the magnitude of the line segment, we are going to use the distance formula between points
We have this as;
D = √(x2-x1)^2 + (y2-y1)^2
D = √(-5-(-1))^2 + (-2-(-4))^2
D = √(-4)^2 + (2)^2
D = √(16 + 4)
D = √20
D = 4.47 units
Marisa had rounded 3.48 to 4 and times it to 7.33 which she rounded to 8
In fact 3.48 is closer to 3 we know this since the .48 of 3.48 s below .50 if it was .50 or above it would round to 4 but it doesn't the same applies to 7.33 so
it should be 3 x 7 = 21
