Using the identity sin^2(t)+cos^2(t)=1
and
given sin(t)=0.3,
we can find cos(t) by substituting
sin^2(t)+cos^2(t)=1
0.3^2+cos^2(t) = 1
cos^2(t)=1-0.3^2=1-0.09=0.91
cos(t)=sqrt(0.91)= 0.954 ≠ 0.6
So the given proposition is false.
The equation describes a linear relationship between x and y. It can be graphed as a straight line. There is nothing to solve until you assign a value to one of the variables, or require they satisfy some additional constraint.
If you want to express it as "y =", then divide by the coefficient of y.
.. y = (-6/5)x -3
.. y = -1.2x -3 . . . . . . in decimal form
The answer is 2.5 cm
First, you multiply 4 and 12, and you get 48
Then you take 120 and you divide it by 48.
This leaves you with 2.5
To check you multiply 2.5, 4, and 12
<u>Answer:</u>
245 days per year ; 1715 hours per year
<u>Step-by-step explanation:</u>
Every emplyoee works 5 days per week , 49 weeks per year. So,
Every employee works,
days = 245 days per year .
Every employee works 7 hours per day,
so, every employee works 
hours
= 1715 hours per year .
