Step-by-step explanation:
Diameter (d) = 22 inch
Radius (r) = d/2= 22/2 = 11 inch
π = 3.14
Now
Circumference = 2πr
= 2* 3.14 * 11
=69.08 ich
And now
Area = πr²
= 3.14 * 11²
= 379.94 inch²
Answer:
7 cm
Step-by-step explanation:
Here is how I solve these problems:
Halve of 6 is 3
10 minus 3 is 7
you subtract 3 from 10 because when you collapse the side (10) onto that side other side (let us call it x), x is shorter that 10 by halve the height.
Answer:
This is confusing.. so all ill say involving 2 and 4.
2 x 4 = 8
2 + 4 = 6
2 - 4 = 2
2 dived by 4 = 2
Decimal form:
2.4 or 4.2
Fraction form:
2/4 or 4/2
Answer:
No. of yellow balloons = r - b - 
Step-by-step explanation:
Total number of balloons = r
No of blue balloons = b
Blue balloons are twice the no of green balloons. so
No. of green balloons =
No of yellow balloons = ( Total number of balloons ) - ( No of blue balloons ) - ( No. of green balloons )
⇒ No. of yellow balloons = r - b -
<span>Your equation is:
f(x) = 7x - 2
Solve for x.
Add 2 to both sides of this equation to get:
f(x) + 2 = 7x
Divide both sides of this equation by 7 to get:
(f(x) + 2)/7 = x
Since, in general, a = b implies that b = a, this equation becomes:
x = (f(x) + 2)/7
Replace x with f(x) and replace f(x) with x to get:
f(x) = (x+2)/7
That's your inverse function.
Graph both your function and your inverse function.
Set y = f(x) to get:
y = 7x - 2 (your regular function).
y = (x+2)/7 (your inverse function).
Graph also the function y = x.
