I need help simplify: 4^8/4^-4

LenKa [72]

Answer:

$4^{12}$

Step-by-step explanation:

using the rule of exponents

$\frac{a^{m} }{a^{n} }$ = $a^{(m-n)}$ , then

$\frac{4^{8} }{4^{-4} }$ = $4^{(8-(-4))}$ = $4^{(8+4)}$ = $4^{12}$

Which pair of undefined terms is used to define a Ray?

REY [17]

Answer:

The undefined terms which are used to define a ray is:

Point and a line.

Step-by-step explanation:

The undefined terms in coordinate geometry are:

Line, Points and Plane.

since a line do not have any length, Point has a location but no size.

A line has no width and it extends infinitely and is one dimensional.

and a plane extends infinitely in both the dimensions.

Ray:

A ray is part of a line, has one fixed endpoint, and extends infinitely along the line from the endpoint.

Hence, the undefined terms which are used to define a ray is:

Point and a line.

Mr. Indigo purchased some trees to plant in his backyard. He bought three oak trees for $23 each and an elm tree for $42. What w

Rom4ik [11]

Answer:

Total cost = $111

Step-by-step explanation:

Given:

Total number of oak tree = 3

Total number of elm tree = 1

Each oak tree cost = $23

Each elm tree cost = $42

Find:

Total cost

Computation:

Total cost = 3[Each oak tree cost] + 1[Each elm tree cost]

Total cost = 3[23] + 1[42]

Total cost = 69 + 42

Total cost = $111

use the plot of the concentration of cu(no3)3 versus absorbance provided. if the absorbance of an unknown was determined to be 0

Helen [10]

Using the linear regression equation, the concentration of the unknown solution is 0.2161 M.

Linear regression describes the relationship of two variables. It may not be exact but it is the line that best fit the data. The equation for a linear regression is in the form y = bx + a, where x and y are the two variables.

If the absorbance of an unknown was determined to be 0.67 absorbance units, using the linear regression equation provided from the plot, substitute the value of absorbance to the variable y and solve for the value of x or the concentration.

y = 3.8674x - 0.1657

0.67 = 3.8674x - 0.1657

3.8674x = 0.67 + 0.1657

3.8674x = 0.8357

x = 0.2161

Hence, the concentration is 0.2161 M.
