Answer:
A(t) = 676π(t+1)
Correct question:
A rain drop hitting a lake makes a circular ripple. Suppose the radius, in inches, grows as a function of time in minutes according to r(t)=26√(t+1), and answer the following questions. Find a function, A(t), for the area of the ripple as a function of time.
Step-by-step explanation:
The area of a circle is expressed as;
A = πr^2
Where, A = Area
r = radius
From the case above.
The radius of the ripple is a function of time
r = r(t) = 26√(t+1)
So,
A(t) = π[r(t)]^2
Substituting r(t),
A(t) = π(26√(t+1))^2
A(t) = π(676(t+1))
A(t) = 676π(t+1)
Answer:
(16√75)/(5√12) = 8
Step-by-step explanation:
Answer:
it's inverse is:
f(x)^-1 = (x+10)/2
Step-by-step explanation:
f(x)= 2x -10
y= 2x -10 [ let f(x) be y]
interchange value of x and y
x=2y -10
(x+10) = 2y
y=(x+10)/2
f(x)^-1 = (x+10)/2
The sequence is as follows:
(17 + 1)(1/2) = 9
(9 + 1)(2/2) = 10
(10 + 1)(3/2) = 16.5
(16.5 + 1)(4/2) = 35
(35 + 1)(5/2) = 90
Therefore, the missing value in the sequence is 10.
Answer:
£65.10
Step-by-step explanation:
42*8 = 336
10% = 33.6
14*15 = 210
10% = 21
5% = 10.5
31.5 +33.6 = £65.10
hope this is correct ^^
