Answer:
x = log 10/log 3
Step-by-step explanation:
3^x - 4 = 6
3^x = 10
We take log base 3 of both sides since log_3 3^x is simply x.
log_3 3^x = log_3 10
x = log_3 10
We have an answer for x, but it is a log base 3. We want log base 10.
Now we use the change of base formula.
log_b y = log y/log b
x = log 10/log 3
The angles of a triangle always add up to 180°.
120 + x + 16 + x = 180
Add up the values.
136 + 2x = 180
Subtract 136 from both sides.
2x = 44
Divide both sides by 2.
x = 22

Diametre = 2 x Radius
Radius = 7
Circumference = 2πr
= 2x22/7x7
= 44
The new equation is
<em>Y = (x-8)² </em>.
The other way to write it is like this: (you might not recognize it in this form)
Y = x² - 16x + 64
