Answer:
The answer is C. 6.4 X 8 in
Step-by-step explanation:
If the scale factor from the original to the trimmed photo is 5:4
The statement above just means the scale of the old dimension is 5 while the scale of the new dimension is 4.
To get the new dimensions, multiply each of the old dimensions by 4/5
4/5 X 10 = 8
4/5 X 8 = 6.4
Therefore the new dimension is 6.4 X 8 in
Answer:
√3
Step-by-step explanation:
cot²(θ) = csc²(θ) -1 . . . . . a relevant identity
= 1/sin²(θ) -1
= (1/(1/2))² -1 = 2² -1 = 3
Then ...
cot(θ) = √3 . . . . . . . . take the square root
Answer: x=3.16m
Step-by-step explanation:
The condition for destructive interference is given by:
∆r = r1 - r2 = (m + 0.5)lamda
Where
Lamda = speed/frequency
= 343/260 = 1.32m
r1. = x
r2 = 2.50m
Then;
X - 2.5 = (m + 0.5)v/f
X - 2.5 = (m + 0.5)1.32
For m = 0 i.e at maximum destructive interference
x = 3.16m
