Answer:
b = 6 or b = -6 (non-zero vectors)
b = 0 (zero vector)
Step-by-step explanation:
Two vectors and are orthogonal if their dot product is equal to 0, or in other words
In your case,
Hence, if vectors a and b are orthogonal, then
Note, then if b = 0, then and zero-vector is orthogonal to any other vectors.
Thus, b = 6 or b = -6.
43.9 + n = 49.65
43.9-43.9 + n = 49.65 -43.9
n = 5.75
Answer:
9 x 24 x 1/2(basically dividing by 2) = 108
, 108 x 2(two triangles) = 216
40 x 15 = 600, 600 x 2(two slanted rectangles) = 1200
40 x 24 = 960 (area of base)
Add given areas:
216 + 1,200 + 960 = 2,376 square feet, B.
Estimate: 6 5/6 rounds to 7 and 1 1/5 rounds to 1 so the estimate is 7/1 which is 7
Find: make the terms both improper fractions: 41/6 and 6/5
Flip the second term and multiply: 41/6 * 5/6
The answer is 205/36
4.67 as a fraction equals 467/100
