Answer:
(
h
∘
f
∘
g
)
(
x
)
is known as a composite function. Here's how composite functions work:
let's say that
x
=
1
. Your function
g
(
x
)
=
1
3
(
x
)
now produces a
y
output of
1
3
, since
g
(
1
)
=
1
3
(
1
)
. Within a composite function, the y-value of one function becomes the x-value of the next, like so:
g
(
1
)
=
1
3
⇒
f
(
1
3
)
=
17
3
⇒
h
(
17
3
)
=
17
Therefore,
(
h
∘
f
∘
g
)
(
1
)
=
17
Based on this, to find the function for
(
h
∘
f
∘
g
)
(
x
)
(combined from right to left, by the way), simply replace
x
in
f
(
x
)
with the function
g
(
x
)
, and replace
x
in
h
(
x
)
with the function of
(
f
∘
g
)
(
x
)
, to get
(
h
∘
f
∘
g
)
(
x
)
.
This, simplified, is equal to
2
x
+
15
, and therefore
(
h
∘
f
∘
g
)
(
1
)
=
2
(
1
)
+
15
=
17
Hope that helps!
Answer:
45
Step-by-step explanation:
Given that the number of savory dishes is 9 and the number of sweet dished is 5.
Denoting all the 9 savory dishes by
, and all the sweet dishes by
.
The possible different mix-and-match plates consisting of two savory dishes are as follows:
There are 9 plates with
from sweet plates which are ![(q_1, p_1), (q_1, p_2), ..., (q_1,p_9).](https://tex.z-dn.net/?f=%28q_1%2C%20p_1%29%2C%20%28q_1%2C%20p_2%29%2C%20...%2C%20%28q_1%2Cp_9%29.)
There are 9 plates with
from sweet plates which are ![(q_2, p_1), (q_2, p_2), ..., (q_2,p_9).](https://tex.z-dn.net/?f=%28q_2%2C%20p_1%29%2C%20%28q_2%2C%20p_2%29%2C%20...%2C%20%28q_2%2Cp_9%29.)
Similarly, there are 9 plated for each
and ![q_5.](https://tex.z-dn.net/?f=q_5.)
Hence, the total number of the different mix-and-match plates consisting of two savory dishes
![= 9+9+9+9+9= 9\times5=45](https://tex.z-dn.net/?f=%3D%209%2B9%2B9%2B9%2B9%3D%209%5Ctimes5%3D45)
This is the formula to solve for the vertex.
Example Question:
Find the vertex of y = -0.5x^2 + 100x
-b/2a = -100/2(-0.5) = -100/-1 = 100
The x coordinate of the vertex is 100.
Best of Luck!
P.S. this is 1000th question i've answered :)
Answer:
1 cup of flour per 12 cookies
Step-by-step explanation:
2x=24y
divide by 2 on both sides
x=12y
