Find the perimeter of triangle ABC. Found your answer to two decimal places.
Perimeter ABC=
Answers
The Perimeter of a triangle ΔABC is 27.68
Given ABC be triangle having vertices A(-2, -1), B(4, 3), C(-5, 7)
We need to find the perimeter of a triangle as
Perimeter of a triangle ΔABC = AB + BC +CA
Now we need to find distances as
D = √ (x₂ - x₁)² + ( y₂ - y₁ )²
AB = √ (4 - (-2))² + ( 3 - (-1) )²
= √ ( 4 + 2 )² + ( 3+1 )²
= √ (6)² + (4)²
= √ 36 + 16
= √ 52
= 7.21
BC = √ ((-5) - (4))² + ( 7 - (3) )²
= √ (-5 -4 )² + ( 7-3 )²
= √ (-9)² + (4)²
= √ 81 + 16
= √ 97
= 9.84
AC = √ ((-5) - (-2))² + ( 7 - (-1) )²
= √ (-5 -2 )² + ( 7+1)²
= √ (-7)² + (8)²
= √ 49 + 64
= √ 113
= 10.63
Perimeter of a triangle ΔABC = AB + BC +CA
= 7.21 + 9.84 + 10.63
= 27.68
Therefore, the Perimeter of the given triangle ΔABC = 27.68

What is the base ten number system, place value?
Base-Ten Number System -The base-ten numeration system is the system that utmost of the world uses moment. No one knows exactly why the number ten was chosen as the base for this system, but it's theorized that it's due to the number of fritters that humans retain. Fingers are veritably fluently assessable as counting tools. The base-ten numeration system consists of ten integers( 0, 1, 2, 3, 4, 5, 6, 7, 8, 9), and groups figures into ten.
2. Understanding Place Value -
Place value refers to the value of each number in a number. For illustration, the number 753 has three" places" or columns each with a specific value. In this three-number number, the 3 is in the" bones " place, the 5 is in the" knockouts" place, and the 7 is in the" hundreds" place.
Beginning ideas of Place Value and Base Ten:
In other words, the 3(three) represents three single units, so the value of this number is three. The 5(five) is in the knockout place, where values increase by multiples of 10(ten). So, the 5(five) is worth (5)five units of 10(ten), or 5(five) x 10(ten), which equals 50(fifty). The 7(seven) is in the hundreds(100) place, so it represents seven units of 100(hundred), or 700(seven hundred).

The altitude of a a in feet of a plain t minutes after lift off is given by a= 3400t + 600 how many minutes after lift off is the plane editive and altitude of 21,000 feet
Answers
The plane will be at an altitude of 21,000 feet, 6 minutes after lift off.
For any equation, x = y + a, if we are given the value of any one of the variables, that is either x or y, we can find the value of the other.
Here, we are given an equation
a = 3400t + 600
where a = altitude of the plane in feet
and t = time (in minutes) passed after the plane's lift off
If the altitude of the plane is 21,000 feet
⇒ a = 21,000
Substituting this in the equation, we get
21,000 = 3400t + 600
21,000 - 600 = 3400t
20,400 = 3400t
3400t = 20,400
t = 20,400/ 3,400
t = 204/ 34
t = 6
Thus, the plane will be at an altitude of 21,000 feet, 6 minutes after lift off.

According to the Pew Research Center Journalism and Media, the estimated circulation of weekday newspapers, in millions, in the United States can be approximated by the formula c = -0.0166x^2 + 1.2109x + 41.708 where x is the number of years after 1940. According to the formula, in what year would the circulation of weekday newspapers be 0 million? Round to the nearest year.
Answers
Step-by-step explanation:
so, simply, when is c = 0 ?
0 = -0.0166x² + 1.2109x + 41.708
the solution to such a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = -0.0166
b = 1.2109
c = 41.708
x = (-1.2109 ± sqrt(1.2109² - 4×-0.0166×41.708))/(2×-0.0166) =
= (-1.2109 ± sqrt(1.46627881 + 2.7694112))/-0.0332 =
= (-1.2109 ± sqrt(4.23569001)/-0.0332 =
= (-1.2109 ± 2.058079204...)/-0.0332
x1 = (-1.2109 + 2.058079204...)/-0.0332 =
= -25.5174459... years
x2 = (-1.2109 - 2.058079204...)/-0.0332 =
= 98.46322904... years
x1 represents then a calculation backwards of 1940 - 25.5 years (≈ 1914) as the estimated starting point with 0 million sold papers.
x2 is the projected year in the future with 0 million dogs papers :
1940 + 98.46322904... = 2038.463229... ≈ 2038
based on this equation it is expected that during 2038 the circulation of weekday newspapers will drop to 0 millions.

You are going down a road with a 5% grade.
You are going down 1 feet every 20 feet horizontally.
The slope of the road as a reduced fraction is??
Answers
The slope of the road as reduced fraction [tex]\frac{1}{20}[/tex] for grade which is 5%.
The slope of a road is defined as the ratio of the vertical height that a road rises to the horizontal distance covered to rise to that height.
While slope is expressed as a fraction grade is the percentage form of that fraction. The slope can also be defined as [tex]tan[/tex] [tex]\theta[/tex] where [tex]\theta[/tex] is the angle of elevation of the road. For example a slope of [tex]\frac{1}{4}[/tex] has a grade of 25%.
Here the given grade is 5%.
Per-cent refers to per one-hundred. So a 5% grade is 5 per one -hundred.
That means if the road is climbing then for every 100 units of horizontal distance covered, the altitude increases by 5 units.
Now slope of the road=vertical distance ÷ horizontal distance
[tex]=\frac{5}{100}\\=\frac{1}{20}[/tex]
Therefore we can say that the slope of the road is [tex]\frac{1}{20}[/tex]
