Answer:
Step-by-step explanation:
arithmetic sequence: 60,68,76,......
a = 60
d = 68 - 60 = 8
an = a + (n-1)*d
a20 = 60 + 19 * 8
= 60 + 152
= 112
There are 112 seats in the 20th row
<span>First of all to calculate the distance between two points we can use distance formula
d=Square Root [(x2-x1)^2 + (y2-y1)^2]
Now substitute the given points p(x1,y1) and q(x2,y2)in above distance formula
The values are X2=3, X1=8and Y2=8and Y1=2.
After Substituting the values
d=Square Root[(-5)^2+(6)^2]
d=Square Root(25+36]
d=Square Root[61]
d=7.8
7.8 is the distance between points P(8, 2) and Q(3, 8) to the nearest tenth.</span>
we are given

For finding inverse function , we do following steps
step-1:
Set f(x)=y

step-2:
Switch x and y

step-3:
now, we can solve for y

Multiply both sides by 9y-2



Add both sides by 2x


now, we can divide both sides by 9x

so, we get inverse function as
