Answer:
Circle B has a larger circumference.
Step-by-step explanation:
Circumference of a circle is the diameter times pi.
C = pi•d
Circle B has radius 5, so its diameter is 10. Circle A has diameter of 9. A larger diameter will give a larger circumference.
C_circle A = 9pi
~= 28
While,
C_circle B = 10pi
~= 31
Circle B's circumference is about 3 cm larger. More accurately it's 1pi larger.
Answer:
Step-by-step explanation:
We are given the function:
And that:
And we want to determine the value of <em>c</em>.
Recall that by definition of inverse functions:
So, since f⁻¹(5) = -1, then f(-1) = 5.
Substitute:
Simplify:
Combine like terms:
And divide. Hence:
In conclusion, the value of <em>c</em> is -2.
Answer:
it is b
Step-by-step explanation:
Answer:
Joe still owes his dad $121.83
Step-by-step explanation:
Joe's new loan balance after paying his dad = amount he owes his dad - joes profit
Joe's profit from working as a waiter = Revenue - cost of renting a uniform
Revenue = amount earned for total hours worked + tips
total hours worked = 4 hours + 2.5hours = 6.5 hours
amount earned for total hours worked = 6.5 x $17.50 = $113.75
Revenue = $113.75 + $35.80. = $149.55
Joe's profit = $149.55 - $21.38 = $128.17
Loan balance = $250 - 128.17 = $121.83
Alternatively, the equation provided in the question can be used :
250 – 17.5(4 + 2.5) – (35.80 – 21.38)
250 - 113.75 - 14.42
= $121.83
Step-by-step explanation:
Union = elements of A + elements of B
Union = ( 1,6,7,9,12)
