Answer:
vw= 22
Step-by-step explanation:
To find the dot product of vw, multiply the corresponding numbers and add them.
v= <3, -8, -3> w= <-4, -2, -6>
vw= (3*-4)+(-8*-2)+(-3*-6)
vw= -12+16+18
vw= 4+18
vw= 22
Answer:
3.5m
Step-by-step explanation:
Volume of pyramid = lwh÷3
25.77 = [(4.7)² × x] ÷ 3
25.77 × 3 = 22.09x
77.31 = 22.09x
x = 77.31 ÷ 22.09
= 3.49
= 3.5m
