Answer:
see below
Step-by-step explanation:
csc(x)tan(x)=
rewrite in terms of sin and cos (csc = 1/sin; tan = sin/cos)
(1/sin(x)) (sin(x)/cos(x))=
the sin(x) cancel out and you are left with 1/cos(x)
Answer:
248.39
Step-by-step explanation:
421 × .59 =248.39
Answer:
0.02 or 2%
Step-by-step explanation:
The probability that test A is negative if the illegal drug has been used (P(A|N)) is 0.1 while the probability that test B is negative if the illegal drug has been used (P(B|N)) is 0.2.
Therefore, the probability that neither test is positive if the illegal drug has been used is:
There is a 0.02 or 2% probability that neither test is positive if the illegal drug has been used.
Answer:
5 years
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
then, solving our equation
t = 1200 / ( 6000 × 0.04 ) = 5
t = 5 years
The time required to
accumulate simple interest of $ 1,200.00
from a principal of $ 6,000.00
at an interest rate of 4% per year
is 5 years.
D) y + 3 = -6(x + 9)
The equation for point-slope form is y - y1 = m(x - x1) where (x1, y1) is a point and m is the slope.
Substitute the values in to get y - (-3) = -6(x - (-9)).
Now, simplify a little bit.
y + 3 = -6(x + 9)
There’s the answer.
