Answer:
honestly,I also really didn't know the ans so I took it from internet. hope you won't mind
It's not rigid because dilations (scale factor not equal to 1) change the length of the segments, or the distances between the points. You'll get a similar figure but it won't be congruent. For example, if the scale factor is 3, then the distances will be three times as large; or the lengths will be 3 times as long.
To be "rigid", the lengths must be kept the same. In contrast, a reflection is rigid because the distances are kept the same. The only thing changing is the orientation (clockwise to counter-clockwise, or vice versa).
Answer:
-81 - y
Step-by-step explanation:
To simplify the expression -3[2-(y-5)]-4[3(y+1)-(6-y)(-2)] use order of operations or PEMDAS.
-3[2-(y-5)]-4[3(y+1)-(6-y)(-2)]
-3[2-y+5]-4[3y + 3+12 -2y]
-3[7-y] -12y-12-48+8y
-3[7-y] - 4y - 60
-21 + 3y - 4y - 60
-81 - y
Answer: 12.56 ft²
<u>Step-by-step explanation:</u>
Perimeter of a circle is known as the circumference.
C = 2π·r where r is the radius.
Perimeter of the curve of the quarter circle + both sides
A = π·r²
