Answer:
auto correlation is the answer to the question
9514 1404 393
Answer:
(c) 52.0
Step-by-step explanation:
The angle whose cosine is 8/13 is found using the inverse cosine function:
y° = arccos(8/13) ≈ 52.0°
y ≈ 52.0
__
The calculator button to compute this value is probably labeled cos⁻¹. You may need to access the function using a <em>Shift</em> or <em>2nd</em> key. The calculator must be set to degrees mode to prevent the answer from appearing in radians or grads. If you use a spreadsheet, your formula may look like ...
=DEGREES(ARCCOS(8/13))
The ends of the rectangle = 10*10*2 = 200
The long sides and bottom of the rectangle = 12*10*3 = 360
Vertical end of the triangle = 5*10 = 50
The sides of the triangle = 12*5*1/2*2 = 60
Triangle slope = 13*10 = 130
Total = 200 + 360 + 50 + 60 + 130 =
800 in sq
19, 13
is the two blank answer due to the fact it's minus six each number
