Secant function is the inverse of cosine function while cotangent is the inverse of tangent function equal to cosine over sine. when we multiply both inverse functions, the result is cos2 x over sin x. cos2 x is equal to 1 - sin2 x. the simplified form is csc x - sin x
Answer:
0.51
Step-by-step explanation:
-32÷(-61)
in this case the subtraction have to cancel themselves
so it'll remain
32÷61
=0.508
approximately ~=0.51
This is a problem of guess and check; there's no easier way to do it.But in this case you must have an odd number of nickels to make the 5 cents, so your answer is 9 nickels.you can check this by multiplying each one by .05:
9*.05=.45
the rest of the coins left, are 8 of them, and their dimes.
.10*8=.80
.80+.45= 1.25
Answer:56.36
Step-by-step explanation:
Answer:
Part A: -3/7
Part B: y = -2
Step-by-step explanation:
Parallel lines have the same slope. Find the slope of CD. Then substitute it to find the value needed for AB.
The slope formula is
Use the same formula and solve for y.
