Answer:
350 Pages or 70 pages a day
Step-by-step explanation:
If the book is 400 pages long and she already read 50 pages she only needs to read 350 pages.
Given that f(x) = 2x + 11: if f(x) = y = 21, then 21 = 2x + 11, and so 10=2x and x=5.
Thus, f(5) = 2(5) + 11 = 21; (5,21) is a point on the graph of f(x).
If that is so (which it is), then (21,5) is a point on the graph of the inverse function, and 5 is the appropriate output value.
Answer:
AE = 43.2 units
Step-by-step explanation:
As per the given question image, it can be seen that in the 
1. 
2.
is common to both the triangles.
3. Two angles are common, so the third angle
is also equal to
.
All the three angles in the
are equal to each other, hence the triangles are similar.
As per the property of similar triangles, the ratio of their sides will be equal.
AB : AC = AE : AD
AC = 88 units
BC = 55 units
AB = AC - AB = 33 units
Let side AE =
units
Side AD = AE + ED
So, AD = 
Using the ratio:

So, AE = 43.2 units
34.06 is the the correct way of saying it.
