Answer:
the correct answer is B. 135 cu. units
Answer:
75 degrees
Step-by-step explanation:
both the angles must add up to 18.
180 - 105 = 75
105 + 75 = 180
Answer:
y = 25 (for x less than/equal to 12)
y = 25 + 1.25(x - 12) for x > 12
For x = 20
y = 25 + 1.25(20 - 12)
y = 25 + 10
y = $35
Answer:
1.32
Step-by-step explanation:
Consider ...
x = sec⁻¹(4) . . . . . the inverse secant function of 4, also written arcsec(4)*
Taking the secant of both sides, we have ...
sec(x) = 4
Writing this in terms of more familiar functions, it is ...
1/cos(x) = 4
cos(x) = 1/4
Now, we can use a calculator to find the inverse function. Be sure the calculator is in the appropriate angle mode. We suspect the desired result is in radians.
x = cos⁻¹(1/4) ≈ 1.318116
sec⁻¹(4) ≈ 1.32 . . . . . radians
_____
* One way to read this is "the angle whose secant is 4." This helps remind you that the result is an angle, so can be in degrees or radians (or any of several other angle measures).
20=5t because you subtract 3t from 8t and you get 5t. then you add 14 to 6 and get 20. so you get 20=5t
