3.2=-0.4n
Please i really confused

Answers

Answer 1

Answer:

n = - 8

Step-by-step explanation:

Given

3.2 = - 0.4n ( isolate n by dividing both sides by - 0.4 )

[tex]\frac{3.2}{-0.4}[/tex] = n , that is

n = - 8

Answer 2

The value of n would be equal to -8.

Noted that equation is an expression that shows the relationship between two or more numbers and variables.

To determine the value of n in equation 3.2 = -0.4n, we will solve for n by isolating it on one side of the equation.

Divide both sides of the equation by -0.4 to isolate n:

3.2 / -0.4

= -0.4n / -0.4

This simplifies to:

-8 = n

Therefore, the value of n is -8.

Find the distance between the parallel lines m and n whose equations are
(y = x + 4) and (y = x - 6.)

Answers

Answer:Find the distance between the parallel lines m and n whose equations are y = x + 4 and y = x - 6, respectively.

There are several ways to do this...here's one

Let (0, 4) be a point on the first line

Then.......a line with a negative reciprocal slope going through this point will have the equation :

y = -x + 4........so......we can find the intersection of this line with y = x - 6....set both equations equal

-x + 4  = x - 6   add x, 6 to both sides

10 = 2x     divide both sides by 2

5  = x

So...using -x + 4, the y value  at intersection  = -1.......

So...we just need to find the distance from  (0,4)  to ( 5, -1)  =

√[ (5)^2 + (4 + 1)^2 ] =  5√2  ≈  7.07 units

Here's a pic....AB is the distance  with A = (0,4)  and B = (5, -1)

Triangle DEF is a scaled copy of triangle ABC. Two triangles labeled ABC and DEF. Triangle ABC has horizontal side AB with point B to the right of point A and point C is directly above side AB. Triangle DEF has horizontal side DE with point E to the right of point D and point F is directly above side DE. Angle ABC corresponds to angle [ Select ] . Angle BCA corresponds to angle [ Select ] . Segment AC corresponds to segment [ Select ] . Segment BA corresponds to segment [ Select ] .

Answers

Answer:

[tex]\angle ABC[/tex] corresponds to the [tex]\angle D EF[/tex]

[tex]\angle BCA[/tex] corresponds to the [tex]\angle EFD[/tex]

Segment AC corresponds to segment DF.

Segment BA corresponds to segment ED.

Step-by-step explanation:

As per the given statements, kindly refer to the attached figure for the diagrammatic representation of the situation.

Given two triangles: [tex]\triangle ABC, \triangle D EF[/tex].

Horizontal sides are AB and DE with points B and E are on the right side of A and D respectively.

Points C and F are directly above the corresponding sides AB and DE respectively.

Kindly refer to the attached diagram for the representation as per the given situation.

Scaled version of a figure and the original figure are similar to each other.

It means that corresponding sides and angles are equal to each other.

[tex]\angle ABC[/tex] corresponds to the [tex]\angle D EF[/tex]

[tex]\angle BCA[/tex] corresponds to the [tex]\angle EFD[/tex]

Segment AC corresponds to segment DF.

If m DGE=52 and FGE is a right angle, what is the measure of DGF

Answers

Answer:

DGF=38

Step-by-step explanation:

FGE is the total angle that adds up to 90 degree. We know that it is bisected into 2 separate angles where we know DGE is 52 but not DGF.

We use the following information above to make the equation x + 52 = 90 (x represent the unknown degree)

Then you just solve normally where you subtract 53 from 90 and get the solution of x=38.

Very small

Step-by-step explanation:

Answer:

very small

Step-by-step explanation:

Scientific notation is used to shorten numbers that are either very large or small, so negative and positive aren't really relevant answers.

Now you have to determine if the number 9.3 x 10^-8 is very large or small.

When dealing with scientific notation, a negative exponent means the number was originally a decimal and a positive exponent means the number was very large. The exponent is negative 8 so it is very small.  

0.023 = 2.3 x 10^-2

2300. = 2.3 x 10^3

A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
This means that if the object x
x
is in the set of inputs (called the domain) then a function f
f
will map the object x
x
to exactly one object f(x)
f
(
x
)
in the set of possible outputs (called the codomain).
The notion of a function is easily understood using the metaphor of a function machine that takes in an object for its input and, based on that input, spits out another object as its output.


Example: x2 (squaring) is a function
x3+1 is also a function
Sine, Cosine and Tangent are functions used in trigonometry
