Researchers have found that after 25 years of age the average size of the pupil in a
laila [671]

Answer:

At 25 = 6.8612mm

At 50 years = 5.422mm

Step-by-step explanation:

Equation,

d = 2.115Logₑa + 13.669

d = diameter of the pupil

a = number of years

Note : Logₑa = In a (check logarithmic rule)

d = 2.115Ina + 13.669

1. At 25 years,

d = -2.115In25 + 13.669

d = -2.115 × 3.2188 + 13.669

d = -6.807762 + 13.669

d = 6.8612mm

At 25 years, the pupil shrinks by 6.86mm

2. At 50 years,

d = -2.1158In50 + 13.669

d = -2.1158 * 3.912 + 13.669

d = -8.2770 + 13.699

d = 5.422mm

At 50 years, the pupil shirks by 5.422mm

To save this question, I had to plug in the values into the equation.

Solving for Logₑa might be difficult, so instead I used Inx which is the same thing. Afterwards, i substituted in the values and solve the equation for each years.

PLZ HELP ME ,A room in the shape of a rectangular prism measures 15 feet by x feet by 12 feet. Write a simplified expression for
ipn [44]

Answer:

180x ft cubed

Step-by-step explanation:

1) The formula for the volume of a rectangular prism is length x width x height

... shortened it is "lwh"

2) Plug your numbers (and "x") into the equation doesn't tell you which is which, but since we are multiplying it doesn't matter.

It should now look like this "(15)(12)x"

3) Simplify.

180x ft cubed
