<h3>
Answer: angle B = 47 degrees</h3>
========================================
Work Shown:
Use law of cosines to find angle B
b^2 = a^2 + c^2 - 2*a*c*cos(B)
9^2 = 6^2 + 12^2 - 2*6*12*cos(B)
81 = 36 + 144 - 144*cos(B)
81 = 180 - 144*cos(B)
81 - 180 = -144*cos(B)
-99 = -144*cos(B)
-144*cos(B) = -99
cos(B) = (-99)/(-144)
cos(B) = 0.6875
B = arccos(0.6875)
B = 46.5674634422102
B = 47 when rounding to the nearest whole number
Make sure your calculator is in degree mode.
arccos is the same as inverse cosine often labeled 
on calculators.
Answer:
<h2>3 and 7</h2>
Step-by-step explanation:
When x=3 and x=7, the outcome of f(x) and g(x) are the same, 4 and 10 respectively. That means at the value of 3, f(x)=g(x), and at the value of x=7, f(x)=g(x).
Look at your graph there is a y axis and x axis drae a graph that has both y axis and x aixs
Commment and tell me if u need more help
Answer:
Hello There!!
Step-by-step explanation:
Firstly,select three ordered pairs from the table. Secondly,substitute the first pair of values in to the form of the quadratic equation: f(x) = ax^2 + bx + c and then solve for a.
hope this helps,have a great day!!
