Assuming ya meant

to slimplify, we use a variation of the pythagorean identity and a decomposition into the sin and cos
for the pythaogreaon identity

divide both sides by


since

subsitute

recall that

also that cos(x) is an even function and thus cos(-x)=cos(x)
therfore

so we get

decompose them into

and

to get

multiply by

to get

we can furthur simlify to get

the expression simplifies to tan(x)sin(x)
Answer: 10.5 minutes
Step-by-step explanation:
Given: Time taken to read each page of health book = 0.8 minutes
Time taken to take the test at the end = 5.5 minutes
Let x be the number of pages of book to read, then time taken to read pages and take the test is given by :-

If we read 6.25 pages, then time taken to read 6.25 pages and take the test is given by :-

Answer:
y = 3x+4
Step-by-step explanation:
Use the coordinates of the points to find the slope of the line passing through them.
slope = Δy/Δx = (10-4)/(2-0) = 6/2 = 3
Point-slope equation for line of slope 3 that passes through (0,4):
y-4 = 3(x-0)
Slope-intercept form of the equation:
y = 3x+4
In its simplest form it is 37/30 or 1 and 7/30.
