Triangle ABC has coordinates A(-4,1), B(0,-2),and C(4,1).

The perimeter of ∆ABC is ___ units.

Answers

Answer 1

9514 1404 393

Answer:

  18 units

Step-by-step explanation:

The distance formula is used to find the distance between two points:

  d = √((x2 -x1)² +(y2 -y1)²)

For AB, the distance is ...

  d = √((0 -(-4))² +(-2 -1)²) = √(16 +9) = √25 = 5

The distances between the other pairs of points can be found the same way. We have elected to let a spreadsheet do the math. It tells us the perimeter of triangle ABC is 18 units.

What factors of -27 have the sum of 6

Answers

Answer:

9 and -3

Step-by-step explanation:

9 and -3 are both factors of -27 since they can be multiply each other to get -27. Also, they both add up to 6.

The factors of -27 that sum up to 6 are 9 and -3

How to determine the factors of -27 that sum up to 6

From the question, we have the following parameters that can be used in our computation:

Factors = -27

Sum = 6

Let the numbers be x and y

So, we have

xy = -27

x + y = 6

Let x be 9 and y be 3

So, we have

9 * -3 = -27

9 - 3 = 6

Hence, the numbers are 9 and -3

Which point would be on the inverse of this function?

Group of answer choices

(-10, -7)

(-6, -3)

(-2, -5)

(9, 6)

Answers

Point (9, 6) would be on the inverse of this function so option (D) will be correct.

What is a function?

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

Given the sets of coordinates of a function.

An inverse function is the reciprocal of a function and the coordinate of the inverse function is interchanged with the original function.

For example, if (x,y) is the coordinate of the function then (y,x) will be the coordinate of the inverse of the function.

Since option (D) (9, 6) is the interchange of (6,9) so it will be the inverse of a function.

Hence "Point (9, 6) would be on the inverse of this function".

Answers

Answer:

Step-by-step explanation:

If student must use conversion given, 3.28ft = 1m, then the following works:

32km/hr = ______mi/da       1 day = 24 hrs, 1m=3.28ft, 1km=1000m,1mi=5280ft

32km/hr  x  24hr/day  x  1000m/1km  x  3.28ft/1m  x  1mi/5280ft  = 477.09mi/da

If student can use 1km = 0.62mi, some steps can be skipped.

solve each traingle

the bottom one:

the line that cut the traingle, made each angle is 90°

10/sin90° = 5/sin?

sin? = 5sin90°/10 = 1/2

the angle is sin^-1 (1/2) = 30°   ⇒

10/sin90° = ?/sin60°

? = 10sin60°/sin90° = 5√3   ⇒

12/sin90° = 5√3/sin?

sin? = 5√3 sin90°/12 = 5√3 /12

? ≈46°

180 - (46+90) = 44°   ⇒

x/sin44° = 12/sin90°

x = 12sin44°/sin90° = 8.3

x = 8 1/3

Answers

Answer:

20.

Step-by-step explanation:

1) according to the condition RT=ST+RS;

2) if RT=4x, ST=3x-8; RS=4x-7, then it is possible to re-write the equation as:

4x=(3x-8)+(4x-7);

3) if to solve this equation, then:

4x=7x-15; ⇔ 3x=15; ⇔ x=5.

4) if x=5, then the length of RT is:

Answers

9514 1404 393

Answer:

  C.  (x -1)/(x +7)

Step-by-step explanation:

The factor (x +1) in the numerator cancels the same factor in the denominator, leaving the ratio (x -1)/(x +7). This matches choice C.

_____

Additional comment

Even though (x+1)/(x+1) = 1 and can be removed from the expression, the fact that it is undefined at x=-1 means the reduced ratio (x-1)/(x+7) is only a valid representation of the original ratio when x≠-1. The factor (x+1) may be gone, but the domain restriction associated with it remains.

Unit 1: geometry basics homework 2: segment addition postulate I need the answers for this worksheet please and thank you

Answers

The answers to the segment addition problems are :

LN = 37MN = 23 EF = 58

The required worksheet is attached below :

A segment is simply the shortest distance between two points, For a line segment, it is the line which connects two points.

Given that :

LM = 22 ; MN = 15

The segment LN is defined as :

LN = LM + MN

LN = 22 + 15

LN = 37

2.)

LN = 54

LN = 54 LM = 31

The line segment, LN equals :

LN = LM + MN

54 = 31 + MN

MN = 54 - 31

MN = 23

3.)

DF = 9x - 39

DE = 47

EF = 3x + 10

The line segment, DF equals ;

DF = DE + EF

9x - 39 = 47 + (3x + 10)

9x - 39 = 47 + 3x + 10

9x - 3x = 47 + 10 + 39

6x = 96

x = 96 / 6

x = 16

Hence,

EF = 3x + 10

EF = 3(16) + 10

EF = 48 + 10

EF = 58
