Go to the third pic for your answer. I got problem 4 wrong but it shows the correct answer.
Answer:
£765
Step-by-step explanation:
Answer:
Ф = ![\frac{\pi }{4} ,\frac{5\pi}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cpi%20%7D%7B4%7D%20%2C%5Cfrac%7B5%5Cpi%7D%7B4%7D)
Step-by-step explanation:
It is a bit difficult to input the work here, so I uploaded an image
- First we can use the trig identities to change sec²(Ф) to tan²(Ф) + 1
- Then we can combine like terms
- Then we can factor this as a polynomial function
- Then we can set each term equal to zero and solve for Ф
- The first term tan(Ф) - 2 = 0 has no solution because tan(Ф) ≠ -2 anywhere
- The second term tan(Ф) - 1 = 0 has two solutions of
and
so these are the solutions to the problem
Answer:
question 1: m = 3/2
question 2: m = 1/95
Step-by-step explanation:
Slope intercept form of equation is of form
y = mx+c
where m is the slope of line and c is the y intercept of the line.
Y intercept is point on y axis where the line intersects the y axis.
____________________________________
given
y = 3/2 x
comparing it with y = mx+c
we have m = 3/2 .
since y = 3/2 x does not have constant term so it can be taken as 0. hence c is 0
_________________________________________
slope for any two point (x1,y1) and (x2,y2) on coordinate plane is given by
slope = (x2-x1)/y2-y1)
From the given table lets take two point as (2,190) and(4,380)
Thus, slope m is given by
m = (4-2)/(380-190) = 2/190 = 1/95
m = 1/95
Though, slope can be taken by dividing y by x (y/x). It is good practice to use two point form formula as given above . Provided two points are given

Answer:
x=14.4
Step-by-step explanation:
x=![\sqrt{h^2-a^2} \\](https://tex.z-dn.net/?f=%5Csqrt%7Bh%5E2-a%5E2%7D%20%5C%5C)
x=![\sqrt{28^2-24^2}](https://tex.z-dn.net/?f=%5Csqrt%7B28%5E2-24%5E2%7D)
x=![\sqrt{784-576}](https://tex.z-dn.net/?f=%5Csqrt%7B784-576%7D)
x=![\sqrt{208}](https://tex.z-dn.net/?f=%5Csqrt%7B208%7D)
x=14.4
