the length of each side of this regular pentagon is 37 mm. what is the perimeter
Answer:
185mm
Step-by-step explanation:
37 times 5 is 185
Answer:
185 mm
Step-by-step explanation:
There are 5 sides in a pentagon. Each side is 37 mm. Add 37 5 times or multiply 37 by 5.
37mm + 37mm + 37mm + 37mm + 37mm
or
37mm × 5
JK is formed by J(-12, 3) and K(8,-5). If
line r is the perpendicular bisector of JK, write
an equation for r in slope-intercept form??
Given:
JK is formed by J(-12, 3) and K(8,-5).
Line r is the perpendicular bisector of JK.
To find:
The equation of line r is slope intercept form.
Solution:
Line r is the perpendicular bisector of JK. So, it passes through the midpoint of J and K.
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-12+8}{2},\dfrac{3+(-5)}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-4}{2},\dfrac{-2}{2}\right)[/tex]
[tex]Midpoint=\left(-2,-1\right)[/tex]
Slope of JK is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{-5-3}{8-(-12)}[/tex]
[tex]m=\dfrac{-8}{20}[/tex]
[tex]m=\dfrac{-2}{5}[/tex]
Product of slopes of two perpendicular lines is -1.
[tex]m_1\times m_2=-1[/tex]
[tex]-\dfrac{2}{5}\times m_2=-1[/tex]
[tex]m_2=\dfrac{5}{2}[/tex]
The slope of perpendicular line r is [tex]\dfrac{5}{2}[/tex] and it passes through (-2,-1). So, the equation of perpendicular line is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-(-1)=\dfrac{5}{2}(x-(-2))[/tex]
[tex]y+1=\dfrac{5}{2}(x+2)[/tex]
[tex]y+1=\dfrac{5}{2}x+5[/tex]
[tex]y=\dfrac{5}{2}x+5-1[/tex]
[tex]y=\dfrac{5}{2}x+4[/tex]
Therefore, the equation of line r is [tex]y=\dfrac{5}{2}x+4[/tex].
The required equation of line "r" in slope-intercept form is y = 5/2x + 15
First, we need to find the equation of a line in slope-intercept form as
y = mx + b
m is the slope of the line
b is the y-intercept
Given the coordinate points J(-12, 3) and K(8,-5)
Get the slope of the line
Slope = -5-3/8+12
Slope = -8/20
Slope - -2/5
Slope of the line "r" perpendicular is 5/2
Get the y-intercept of line r
Substitute (8, -5) and m = 5/2 into y = mx + b
-5 = -5/2(8) + b
-5 = -20 + b
b = 15
Hence the required equation of line "r" in slope-intercept form is y = 5/2x + 15

What is expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.
An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:
Constant: A constant is a fixed numerical value.Variable: A variable is a symbol that doesn't have a fixed value.Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.Coefficient: A coefficient is a number that is multiplied by a variable in an expression.Given:
5(2x - 3) - 3(x + 4) / 9
=10x-15-3x-12/9

Step-by-step explanation:
Let f = number of friends
all but one friend got 6 pieces and 1 friend got 2 for a total of 50 pieces
6(f-1) + 2 = 50
Subtract 2 from each side
6(f-1) +2-2 = 50-2
6(f-1) = 48
Divide by 6
6(f-1)/6 = 48/6
f-1 = 8
Add 1 to each side
f-1+1=8+1
f=9

What is a group of objects that share common characteristics and are well-defined?
Answer:
The options as included in the attachment section are:
A. real numbers B.Cardinality C.element D.Set
The answer is D. Set
Step-by-step explanation:
In mathematics, a set is a group of well-defined objects that share common characteristics as rightly stated in this question. So in a mathematical calculation, the elements or objects collected as a group is called SET. The types of set include empty set, finite set, infinite set, universal set etc.
- Since set represents the whole collection or group, each object, which can be number, letter etc. in the group is an ELEMENT. Likewise, the cardinality of a set refers to the number of elements contained in a particular set.
HELLLLLLLLp i dum please help me
Answer:

Step-by-step explanation:
(6[tex]x^{5}[/tex]z)^3
6^3 is 226
*(x^2)^3= x^6 (5*3= 15)
*when there are exponents being raised to a power, the exponents are multiplied
**(z^1)^3= z^3 (3*1= 3)
** all numbers are raised to the 1st power (unless otherwise noted x^2, 5^4 2^2, etc)
So the top would end up being 226x^6z^3
Now, since this number is over 4x^4z^2, you need to divide 226x^15z^3 by 4x^4z^2
**divide like terms**
226/4= 54
***x^15/ x^4= x^x^11
*** when you divide exponents, you subtract the bottom number from the top, in this case:
15-4
that equalls 11
So x^11
you do the same for z:
z^3/z^2= z^1 or z (3-2=1 )
You put it all together and you end up with
54x^11z

The additive inverse of -7
Answer:
7
Step-by-step explanation:
An "additive inverse" refers to a number that when added to a specific number equals to "zero."
In the question above, the additive inverse of -7 is 7 because: -7 + 7 = 0
Other examples:
1. The additive inverse of 2 is -2 because: 2 + (-2) = 0
2. The additive inverse of -100 is 100 because: -100 + 100 = 0
3. The additive inverse of [tex]\frac{1}{2}[/tex] is -[tex]\frac{1}{2}[/tex] because: [tex]\frac{1}{2}[/tex] + -[tex]\frac{1}{2}[/tex] = 0
The additive inverse of -7 is equal to 7.
The additive inverse of a number is the number that, when added to the original number, gives a sum of zero.
To determine the additive inverse of -7, we need to find the number that, when added to -7, results in zero.
To do this, we can multiply -7 by -1, which is the multiplicative inverse of 1. Multiplying a number by its multiplicative inverse always gives the additive inverse of that number.
So, -7 multiplied by -1 is:
-7 x -1 = 7
Therefore, the additive inverse of -7 is 7.
