What is an equation of the line that passes through the point
mash [69]

Answer:

The Answer is: y = 1/4x + 6

Step-by-step explanation:

Given point (8, 8)

Given equation: 4x + y = 5

Solve for y:

y = -4x + 5

The slope is -4. The slope of a perpendicular line is the negative inverse, which would be 1/4.

Use the point slope form:

y - 8 = 1/4(x - 8)

Solve for y:

y - 8 = 1/4x - 8/4

y - 8 = 1/4x - 2

y = 1/4x - 2 + 8

y = 1/4x + 6

colby and jaquan are growing bacteria in an experiment in a laboratory. Colby starts with 50 bacteria in his culture and the num
kaheart [24]
To get started, we will use the general formula for bacteria growth/decay problems:

A_{f} =  A_{i} ( e^{kt} )

where: 
A_{f} = Final amount
A_{i} = Initial amount
k = growth rate constant
t = time


For doubling problems, the general formula can be shortened to:

kt = ln(2)

Now, we can use the shortened formula to calculate the growth rate constant of both bacteria:

Colby (1):
k_{1} = ln(2)/t
k_{1} = ln(2)/2 = 0.34657 per hour

Jaquan (2):
k_{2} = ln(2)/t
k_{2} = ln(2)/3 = 0.23105 per hour

Using Colby's rate constant, we can use the general formula to calculate for Colby's final amount after 1 day (24 hours).

Note: All units must be constant, so convert day to hours.

A_{f1} = 50( e^{0.34657(24)})
A_{f1} = 204,800

Remember that the final amount for both bacteria must be the same after 24 hours. Again, using the general formula, we can calculate the initial amount of bacteria that Jaquan needs:

A_{f2} = 204,800 =  A_{i2} ( e^{0.23105(24)} )
A_{i2} = 800
