Answer:
f (x)
[tex] \ frac [7] [4] \ time 2x [\tex]
then f (1/7) = 1/2
Answer:
pretty sure its C
Step-by-step explanation:
Answer:
D is the correct answer
Step-by-step explanation:
Since 5x and 4x+1 are both equal to y, we can set them equal to each other as shown below:
5x=4x+1
x=1
Plugging x=1 into y=5x gets us y=5(1)=5
So x=1 and y=5, which is also (1,5)

Answer:
<u>Option B: sin Ф cos² Ф</u>
Step-by-step explanation:
Given expression:
![\frac{sin^2 \phi}{csc \ \phi \ * tan^2 \ \phi} = \frac{sin^2 \phi}{\frac{1}{sin \ \phi}*\frac{sin^2 \phi}{cos^2 \phi} } = sin \ \phi * cos^2 \ \phi](https://tex.z-dn.net/?f=%5Cfrac%7Bsin%5E2%20%5Cphi%7D%7Bcsc%20%5C%20%5Cphi%20%5C%20%2A%20tan%5E2%20%5C%20%5Cphi%7D%20%3D%20%5Cfrac%7Bsin%5E2%20%5Cphi%7D%7B%5Cfrac%7B1%7D%7Bsin%20%5C%20%5Cphi%7D%2A%5Cfrac%7Bsin%5E2%20%5Cphi%7D%7Bcos%5E2%20%5Cphi%7D%20%20%7D%20%3D%20sin%20%5C%20%5Cphi%20%2A%20cos%5E2%20%5C%20%5Cphi)
Note:
csc Ф = 1/sin Ф
tan Ф = (sin Ф)/(cos Ф)
