Answer:
Reflection across y axis
Translate up by 3 units
Step-by-step explanation:
Given


Required
Describe the transformation from f(x) to g(x)
First, take a reflection of f(x) across the y axis.
So f(x) becomes f(-x)
when reflected

Next, translate f(-x) up by 3 units to give g(x)

Where




Hence, the transformation from f(x) to g(x) includes:
Reflection across y axis
Translate up by 3 units
Answer:
(C) r=5.2 in
Step-by-step explanation:
firstly, we will draw diagram
we know that
centroid divides altitude into 2:1 form
so, we get

now, we can plug
h=7.794


so, option-C...............Answer
Answer:
f(x) = -3x + 12
Step-by-step explanation:
The chart could be represented like this:
x y
0 12
1 9
2 6
3 3
Suppose that f(x) = y
And substitute x values.
y = -3x + 12
"x = 0"
y = -3(0) + 12
y = 0 + 12
y = 12
"x = 3"
y = -3(3) + 12
y = -9 + 12
y = 3
From the results, it corresponds to the function.
Answer: option a.
Step-by-step explanation:
By definition, we know that:

Substitute
into the first equation, solve for the cosine and simplify. Then, you obtain:

As
then
:

Now we can find
:
