Answer:
5
Step-by-step explanation:
The equation of a straight line is :
y=mx+c
where m is the gradient and c is the y-intercept
so if m equals 5 then the gradient is 5
U use sin
sin50 = b/10
b=10(0.76)
b=7.6
Answer:

Step-by-step explanation:
The inverse function can be found by solving ...
f(y) = x
(√y)/5 +2 = x
(√y)/5 = x -2 . . . . . subtract 2
√y = 5(x -2) . . . . . . multiply by 5
y = 25(x -2)² . . . . . square both sides
The inverse function is ...

_____
<em>About the graph</em>
The inverse of a function is its mirror image across the line y = x.
There are two ways for finding p, here is one way:
1/2 = 4p
Multiply both sides by 2:
1 = 8p
Divide both sides by 8:
0.125 = p
Answer:
p = 0.125
