Measure of PQB is 15.4 because QB bisects PQR into 2 equal angles and measure of PQR is 2(15.4)=30.8
Answer:
Analyzed and Sketched.
Step-by-step explanation:
We are given
.
We need to find the following to sketch the graph.
1) First derivative of y with respect to x to determine the interval where function increases and decreases.
2) Second derivative of y with respect to x to determine the interval where function is concave up and concave down.

The roots are x = -1/2 and x = 1/2 but negative one cannot be possible due to logarithmic function.
x = 1/2 is absolute maximum.

So, concavity is always down.
Here, x = 0 is vertical asymptote.
I attached the picture of sketched graph.
Answer:
Area = 6x - 6
Step-by-step explanation:
Given:
Height = 2x - 2
Base = 6
Required:
Area
Solution:
Area of triangle = ½*b*h
Area of the triangle = ½*6*(2x - 2)
Area = 3(2x - 2)
Apply distributive property
Area = 6x - 6
The correct answers are :
x + y = -1
x + 4y = 0
8x - 3y = 20
