A car travels at a speed of 85 miles per hour. How far will it travel in 15 mins?
marusya05 [52]

In this question, we're trying to find how many miles a car travels in 15 minutes.

We know that the car travels at 85 mph.

However, we need to know how many miles it travels per minute.

To find this, we would divide 85 by 60.

85 ÷ 60 = 1.4166

The car drives at a speed of about 1.42 per minute.

We need to know how far it goes in 15 minutes, so multiply 1.42 by 15.

1.42 · 15 = 21.3

The car travels at a approximately 21.3 miles in 15 minutes.

If $396 is invested at an interest rate of 13% per year and is compound continuously, how much will the investment be worth in 3
Sveta_85 [38]

Answer:

The investment at the end of the period will be $584.89.

Step-by-step explanation:

FV = PV e⁽ⁿˣ⁾

FV = Future Value = ?

PV = Present Value = $396

n = Interest Rate = 13%

x = time in years = 3

e = mathematical constant = 2.7183

FV = 396 x 2.7183⁽⁰°¹³ ˣ ³⁾

FV = 396 x 1.4770

FV = $584.89

How are percent transmittance and absorbance related algebraically?
statuscvo [17]

Answer:

So, if all the light passes through a solution without any absorption, then absorbance is zero, and percent transmittance is 100%. If all the light is absorbed, then percent transmittance is zero, and absorption is infinite.

Absorbance is the inverse of transmittance so,

A = 1/T

Beer's law (sometimes called the Beer-Lambert law) states that the absorbance is proportional to the path length, b, through the sample and the concentration of the absorbing species, c:  


A ∝ b · c

As Transmittance, T =\dfrac{P}{P_0}

% Transmittance, \%T=100\times T

Absorbance,

A=\log_{10} \dfrac{P_0}{P}\\\\A =\log_{10}\times \dfrac{1}{T}\\\\A=\dfrac{\log_{10} 100}{\%T}\\\\A=(2 - log_{10})\times \%T

Hence, A=\log_{10}\times \dfrac{1}{T} is the algebraic relation between absorbance and transmittance.

In the function ƒ(x) = x2 + x + 1, which of the following represents the output value? Select one or more: A. f(x) B. x2 C. x D.
kakasveta [241]

Answer:

The correct answer is f(x)

Step-by-step explanation:

The answer is f(x) because is the result of the quadratic sum, once the function is evaluated. Example:

Let be x= 2

Then f(2)= 4+2+1=7

Therefore the output is f(2) which is equal to 7.
