The answer is A is cross the x axis at (2.2) :)
Answer:


Step-by-step explanation:
<u>Composite Function</u>
Suppose f(x) and g(x) are real functions, the composite function named
is defined as:

The composite function can be found by substituting g into f.
We are given these functions:



Find:
a) h(g(x))
Substituting g into h:

b) h(g(f(x))
First we find g(f(x)):

Operating:

Simplifying:

Now find h(g(f(x)) replacing the above equation into h:

Simplifying and rearranging:


Answer:
it’s not proportional
Step-by-step explanation:
the number that you are always multiplying should be constant
2x9 = 18 but 4x9 does not equal 20
Answer:

Step-by-step explanation:
Let L be the length of the ladder,
Given,
x = the distance from the base of the ladder to the wall, and t be time.
y = distance from the base of the ladder to the wall,
So, by the Pythagoras theorem,

,
Differentiating with respect to time (t),




Here,

Also,
( Ladder length = constant ),




Which is the required notation.
Answer:
Part 1)

Part 2)


Step-by-step explanation:
we know that
In a parallelogram opposite sides and opposite angles are congruent, and consecutive angles are supplementary
Part 1)
<u>Find the value of x</u>
----> opposite sides are congruent
solve for x
<u>Find the value of m</u>
----> consecutive angles are supplementary
solve for m

Part 2)
<u>Find the value of x</u>
---> opposite sides are congruent
using a graphing tool
see the attached figure N 1
The solutions are

<u>Find the value of m</u>
---> opposite sides are congruent
solve for m
using a graphing tool
see the attached figure N 2
The solutions are
