Answer:
Consider the given vectors.
a=3i+2j−6k
b=4i−3j+k
Now,
a⋅b=(3i+2j−6k)(4i−3j+k)
a⋅b=12−6−6=0
Therefore,
Two vectors a and b are perpendicular.
Thus, the angle between the vectors a and b =90∘
Hence, this is the answer.

Answer: D) -304
Step-by-Step Solution:
=> f(x) = 5x - 1
=> g(x) = 2x^2 + 1
=> Find value of (f * g)(-3)
First Substitute x as -3 in f(x) and g(x) :-
f(x) = 5x - 1
f(-3) = 5(-3) - 1
f(-3) = -15 - 1
=> f(-3) = -16
g(x) = 2x^2 + 1
g(-3) = 2(-3^2) + 1
g(-3) = 2(9) + 1
g(-3) = 18 + 1
=> g(-3) = 19
Now Multiply f(-3) with g(-3) :-
= f(-3) * g(-3)
= -16 * 19
=> -304
Therefore, (f * g)(-3) = -304
160% of 19 is 30.4
Convert 160 into a decimal: 160%/100 = 1.6
Multiply the decimal by 19: 1.6 × 19 = 30.4 <-- our answer.
------
0.9% of 54 is 0.486
Convert 0.9% in a decimal: 0.9%/100 = 0.009
Multiply the decimal by 54: 0.009 × 54 = 0.486 <-- our answer.
-------
15% of 376 is 56.4
Convert the percentage into a decimal: 15%/100 = 0.15
Multiply the decimal by 376: 0.15 × 376 = 56.4 <-- our answer.
I think it is B but im honestly unsure.
