Answer:
5/8 of an inch
Step-by-step explanation:
a right angle is 90°, or 1/4 of a circle.
3/5 * 1/4 = 3/20
radian measure is the length of the circumference of this part of the circle.
a full circumference of a circle would be 2*pi*r, also expressed as 2 rad * r
now let's multiply the full thing with the 3/20 from earlier to just get the desired fraction:
6/20 rad * r
<u>= 3/10 rad * r</u>
of course a solution in cm or inch still depends on the radius here, wich could be just plugged in at will

d. False
e. False
Step-by-step explanation:
The matrix with orthonormal column must be in square for that it forms orthogonal matrix. Every orthonormal set of non zero vector is linearly independent. This statement is correct because there is linear combination of non zero vectors.
