Answer:
The value of the given expression is -878.08.
Step-by-step explanation:
Here, the given question is INCOMPLETE.
The complete question is:
Evaluate the expression for a = 4, b = -5, and c = -7.
Here, substitute the vale of a = 4, b = -5 and c = -7, we get:
Hence, the value of the given expression is -878.08.
The number . . . . . N
The difference of the number and 9 . . . N-9
Seven times that difference . . . . . . . 7(N-9)
You said that 7(N-9) = 2 .
Divide each side by 7 : N - 9 = 2/7
Add 9 to each side: N = 9 and 2/7
Well obtuse would be like hmm lets say 10.2, 14.1, and 11.1
so its acute thats all i can do XD
Answer:
$183.3
Step-by-step explanation:
PRT/100 = I
Making P s.o.f
P = 100I/RT
R = 6%
T = 2 years
I = $22
P = 100×22/6×2
= 2200/12
= $183.33
Therefore the principal invested is $183.33

Note tanx = sinx / cosx. What you typed is wrong.
For complementary Angles, that is Angles that add up to 90 degrees.
For example 60 and 30 are complementary. 20 and 70 are also complementary, same is 40 and 50. That is because they both add up to 90.
For Complementary Angles:
sinx = cos(90 - x)
cosx = sin(90 -x)
tanx = cot(90 -x)
cotx = tan(90 -x). cotx = 1/tanx
Therefore tan(90-A) = cotA.
