PLEASE HELP 30 POINTS Wendell is looking over some data regarding the strength, measured in Pascals (Pa), of some building mater

ials and how the strength relates to the length. The data are represented by the exponential function f(x) = 2x, where x is the length. Explain how he can convert this equation to a logarithmic function when strength is 8 Pascals.

Logarithmic functions and exponential functions are inverse and opposite of one another

The logarithmic function is y = \log_2(x), and the length at 8 pascals is 3 units

<h3>How to determine the logarithmic function</h3>

The exponential function is given as:

f(x) = 2^x

Express f(x) as y

y = 2^x

Swap the positions of x and y

x = 2^y

Take the logarithm of both sides

\log(x) = \log(2^y)

Apply the rule of logarithm

\log(x) = y\log(2)

Divide both sides by log(2)

y = \frac{\log(x)}{\log(2)}

Apply the change of base rule of logarithm

y = \log_2(x)

When the strength is 8 pascals, we have:

y = \log_2(8)

Express 8 as 2^3

y = \log_2(2^3)

So, we have:

y =3 \log_2(2)

Evaluate log 2 base 2

y =3

Hence, the logarithmic function is y = \log_2(x), and the length at 8 pascals is 3 units

So, you already know that angle CBD is 68 degrees, and the complementary angle to angle CBD is angle CBA. These angles together make 180 degrees because segment DBA is a straight line consisting of angles CBD and CBA. 180-68(the angle you already know) is 112 degrees for angle CBA. Then you repeat this process to find the other angles

Write the expression "N is the same as 6 reduced by 2" as a number sentence.
Anton [14]

Answer:

N=6-2

Step-by-step explanation:

When speaking the language of math, "the same as" just means equal to. On the left side of the equal sign, you have your variable, and on the right is the rest of the equation. 6 reduced by 2 is the same thing as 6-2

A box is contructed out of two different types of metal. the metal for the top and bottom, which are both square, costs $5 per s
patriot [66]
Total cost, C = 8x^2 + 12xz 
volume, V = (x^2)*z = 10 
C = 8x^2 + 12x*10/x^2 
= 8x^2 + 120/x 
dC/dx = 16x - 120/x^2 = 0 
16x = 120/x^2 
x^3 = 120/16
 x = 1.957 ft

d^2C/dx^2 = 16 +240/x^3 = +ve for x = 1.957 
so, C is minimum when
x = 1.957 ft z = 2.61 ft

Length of the base x is 1.957 ft and height of side z is 2.61 ft
