We are given with the situation of bacteria multiplying into colonies. We are given also with the function of B(t)= 4e^0.8t where t is the time of multiplication. We just have to substiture the given time of 7 hours to find teh final count. The answer is approximately 1082. Answer is B.
f(x) is a linear function with no restrictions
Domain: x = All real numbers
Range: y = All real numbers

Answer:
area will be four times the first area
Step-by-step explanation:
the diameter of the first sphere=d
therefore radius=d/2
=r
the diameter of the second sphere becomes 2d
therefore the radius of second sphere=2r
area of a sphere=4×pi×r^2
the ratio of the two spheres=(4pi(2r)^2)/(4pir^2)
=(4pi4r^2)/4pir^2
cancelling 4pir^2, you get 4:1
therefore the area of the second sphere is 4 times the first one
Step-by-step explanation:
x² + 16x + 64 = (x + 8)². Hence p = 8.
Since (x + 8) is a factor of 4x² + 37x + k,
4(-8)² + 37(-8) + k = 0. (by Factor Theorem)
=> 256 - 296 + k = 0
=> k - 40 = 0
=> k = 40.
The value of k is 40.
