Step-by-step explanation:
In step 2 he confused the multiplication and addition signs
If x terminates in the fourth quadrant, then we know that sin(x) < 0 and cos(x) > 0. Given that sec(x) = 8, we immediately have
cos(x) = 1/sec(x) = 1/8
Recall the Pythagorean identity,
cos²(x) + sin²(x) = 1
Then it follows that
sin(x) = -√(1 - cos²(x)) = -3√7/8
Now recall the double angle identities,
sin(2x) = 2 sin(x) cos(x)
cos(2x) = cos²(x) - sin²(x)
Then
sin(2x) = 2 (-3√7/8) (1/8) = -6√7/64 = -3√7/32
cos(2x) = (1/8)² - (-3√7/8)² = -62/64 = -31/32
By definition of tangent,
tan(x) = sin(x)/cos(x)
Then
tan(2x) = sin(2x)/cos(2x) = (=3√7/32) / (-31/32) = 3√7/31
Answer:
Depending on the unit your answer needs to be in, it would be <u>88 cubic feet</u> or <u>3.25926 cubic yards</u>
If your question asks you to round to the nearest hundredth it would be <u>3.26 cubic yards.</u>
Step-by-step explanation:
To find the volume of soil:
Volume= Length x Width x Depth/Height
Volume= 44ft x 2ft x 1ft
Volume= 88 cubic feet or 3.25926 (there are 27 cubic feet in a cubic yard, 88/27=3.25926)
hope this helps! :)
