Find the measure of each exterior angle of the regular polygon.
Answer:
30°Step-by-step explanation:
Sum of exterior angles of the regular polygon is 360°The pictured is 12-gon
Each exterior angle measures:
360°/12 = 30°Answer:
30 degrees
Step-by-step explanation:
(Sum=360)
360/12=30
(We got 12 because there are 12 sides in the polygon!)

find the slope and explain what the slope represents
write the equation of the line
what does the y-intercept represent
using the equation calculated the length of the spring when 15 ib. of the weight is attached
Answer:
Slope=2
y intercept= Length of spring without any weight
15 lbs= 38 inches
Step-by-step explanation:
slope=
18-12/5-2= 6/3 = 2
y intercept= 0=x and x=amount of weight

Two friends shop for fresh fruit Elena buy a watermelon for 8.55 and 3 pounds of cherries. Taniy buys a pineapple for 2.45 and 2 pounds cherries. Use the variable p to represent the price, in dollars, per pound of cherries. Write and simplify an expression to how much more Elena spent.
Answer:
$6.10 + p
Step-by-step explanation:
Given that:
p = price in $ per pound of cherries
ELENA:
Amount spent = 8.55 + 3p
TANIY:
Amount spent = 2.45 + 2p
How much more Elena spent :
Amount spent by Elena - Amount spent by Taniy
(8.55 + 3p) - (2.45 + 2p)
8.55 + 3p - 2.45 - 2p
8.55 - 2.45 + 3p - 2p
6.10 + p
$6.10 + p

What is the equation, in standard form, of a parabola that models the values in the table?
y=4x^2+5x-6y=4x2+5x−6
:
Given points are :
x = -2 0 4
y=f(x) = 0 -6 78
We have to model the parabola with the help of these points
Solution:
We consider a standard equation of parabola y= ax^2+bx+cy=ax2+bx+c
now, we put the points in the equation we get,
at (-2,0) is 4a-2b+c=0
at (0,-6) is c=-6
at (4,78) is 78= 16a+4b+c
now, solving these equation we get, a= 4 , b= 5 , c= -6
so the equation formed with these points is y=4x^2+5x-6y=4x2+5x−6
we can see this in the graph attached.

Consider the polynomial function:
p(x) = 3x3 + 10x2 + ax - 6
where a is an unknown real number.
If
(x + 3)
is a factor of this polynomial what is the value of a? Show all the steps below.
Step-by-step explanation:
By Factor Theorem, p(-3) = 0.
Therefore 3(-3)³ + 10(-3)² + (-3)a - 6 = 0 and a = 1.

Angela transfers 15% of each paycheck she received into her savings account. If she transferred $54 into her savings account last week, how much did she earn on that paycheck? Show your work using a model, proportion or equation
Answer:
$360
Step-by-step explanation:
Let the amount that she earned on the paycheck be represented by x
Hence,
15% of x = $54
Therefore:
15/100 × x = $54
15x/100 = $54
Cross Multiply
15x = $54 × 100
15x = $5400
x = $5400/15
x = $360
Therefore, the amount that she earned on that paycheck = $360
Given: \overline{BD} \cong \overline{BE}, BD ≅ BE , \overline{DE} DE bisects \overline{AB} AB and \overline{DE} DE bisects \overline{BC}. BC . Prove: \overline{AB} \cong \overline{BC} AB ≅ BC .
Given:
[tex]\overline{BD} \cong \overline{BE}[/tex]
DE bisects [tex]\overline{AB}[/tex].
DE bisects [tex]\overline{BC}[/tex].
To prove:
[tex]\overline{AB} \cong \overline{BC}[/tex]
Proof:
DE bisects [tex]\overline{AB}[/tex]
Then, [tex]AD=BD[/tex]. ...(i)
DE bisects [tex]\overline{BC}[/tex].
Then, [tex]BE=CE[/tex]. ...(ii)
We have,
[tex]\overline{BD} \cong \overline{BE}[/tex] ...(iii)
Using (i), (ii) and (iii), we get
[tex]\overline{AD} \cong \overline{CE}[/tex] ...(iv)
Adding (iii) and (iv), we get
[tex]\overline{BD}+\overline{AD} \cong \overline{BE}+\overline{CE}[/tex]
[tex]\overline{AB} \cong \overline{BC}[/tex]
Hence proved.
make m the subject of g-3m=am+5
Answer:
m = (g - 5) / (a + 3)
Step-by-step explanation:
g-3m=am+5
Get all the m's on one side.g - 5 = am + 3m
Combine the m's into one term, using bracketsg - 5 = (a + 3)m
Get m on it's own by dividing by a + 3(g - 5) / (a + 3) = m
Answer:
[tex]\displaystyle m=\frac{g-5}{3+a}[/tex]
Step-by-step explanation:
Equation Solving
To solve an equation for a specific variable, we perform a sequence of steps to have that variable isolated or make it the subject of the equation.
We are given the expression:
[tex]g - 3m=am+5[/tex]
And it's required to make m the subject of the equation. This means we have to isolate m at the left side of the equation.
First, multiply both sides by -1;
[tex]-g + 3m=-am-5[/tex]
Add am:
[tex]-g + 3m+am=-5[/tex]
Add g:
[tex]3m+am=-5+g[/tex]
The variable m is found in both term, thus we factor it out:
[tex]m(3+a)=g-5[/tex]
Dividing by 3+a:
[tex]\mathbm{\displaystyle m=\frac{g-5}{3+a}}[/tex]

Answer:
15.25 or 15 if you need it to be rounded.
Step-by-step explanation:
-11 on both sides to get 5x=1x+61. Then, -1x on both sides to get 4x=61. Then to find x you do 61 divided by 4 which is 15.25.

Step-by-step explanation:
The first humor bookshelf in the section of a library can hold 2296, books. The bookshelf has 7 shelves. Shelves. Each shelf can hold the same number of books. How many books can each shelf hold? Write an equation to help solve this problem.
They said each shelf can hold the same number of books
And we have 7 shelves
Total number of books = 2296
Hence:
The number of books each shelf can hold = 2296 books/7 Shelves
= 328 books
Hence, each shelf can hold 328 books
An equation to solve this problem =
Number of books can be represented by x
Hence:
7x = 2296

-3 + yi = x + 6i
Answer:
x = - 3, y = 6
Step-by-step explanation:
For the 2 sides to be equal then the coefficients of the imaginary terms and the real terms must be equal.
Given
- 3 + yi = x + 6i , then
x = - 3 and y = 6

Is (x+1)/x^2 greater or less or equal to 1/x
Answer:
(1) x^2 is greater than 1.
(2) x is greater than -1.
(1) x^2 is greater than 1 --> x2>1x2>1 --> x<−1x<−1 or x>1x>1. Sufficient.
(2) x is greater than -1 --> x>−1x>−1. Not sufficient.
