R(t) = 4t
A(r) = π(r^2)
a) A(t) = A[r(t)] = π[r(t)]^2 = π[4t]^2 = 16π(t^2)
b) t = 4,
A(4) = 16*3.14*(16)^2 = 12,861.44
V = 1/3Bh
B = 1/2(b1 + b2)t
V = 1/3[1/2(b1 + b2)t] * h
h = 24
b1 = 13
b2 = 29
t = ?
V = 2856
Substitute:
2856 = 1/3[1/2(13 + 29)t](24)
2856 = 1/6(42)(24)t
2856 = 7(24)t
2856 = 168t
t = 2856/168 = 17 in height of the trapeziod
Answer: 50° Fahrenheit
Step-by-step explanation:
Here, the equation that shows the temperature of x degree Celsius in Fahrenheit is,

Where x is a variable.
Thus, For the temperature of 10° Celsius,
x = 10° Celsius
The temperature in Fahrenheit is,


Thus, the increasing temperature by 10° C is equivalent to increasing temperature by 50° F.
Domain means which values the function can have which make it true or Possible to solve
So all you got to do is set the denominator = to 0 and solve for x
You will get x=7
4/(7-7) is not possible
So x cannot equal to 7 because you cant divide a number by 0!
