A pentagon's lines of symmetry go thru an angle and the middle of a side. Every 72 degrees, the pentagon in split into identical halves. Same with 144 because it is basically 2 72 degree rotations.
Answer:
72
Step-by-step explanation:
The order of rotational symmetry of a regular pentagon is 5.
To find the angle of rotation we divide 360 by the number of sides
360/5=72
so the angle of rotation is 72 degrees.

Find legit BD
I need help for my assignment
Answer:
BD = 4
Step-by-step explanation:
∆BAD is congruent to ∆CAD based on the AAS Congruence Theorem.
Therefore:
BD = CD
3x + 1 = 5x - 1 (substitution)
Collect like terms
3x - 5x = -1 - 1
-2x = -2
Divide both sides by -2
x = -2/-2
x = 1
✔️BD = 3x + 1
Plug in the value of x
BD = 3(1) + 1
BD = 3 + 1
BD = 4

6. If a person adopts a pet, it's either a cat or a dog. 25% of the time, it's a cat and 75% of the time, it's a dog. If you meet someone at the shelter that adopted three pets, what's the probability that they got either: three cats or three dogs? Show your calculation and give your single answer as a decimal.
Answer:
0.0156 probability that they got three cats.
0.4219 probability that they got three dogs.
Step-by-step explanation:
For each person there are only two possible outcomes. Either they adopted a dog, or a cat. The probability of a person adopting a cat or a dog is independent of any other person, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Three people:
This means that [tex]n = 3[/tex]
What's the probability that they got three cats?
25% of the time it's a cat adopted, which means that [tex]p = 0.25[/tex]
This is P(X = 3). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{3,3}.(0.25)^{3}.(0.75)^{0} = 0.0156[/tex]
0.0156 probability that they got three cats.
What's the probability that they got three dogs?
75% of the time it's a dog adopted, which means that [tex]p = 0.75[/tex]
This is P(X = 3). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{3,3}.(0.75)^{3}.(0.25)^{0} = 0.4219[/tex]
0.4219 probability that they got three dogs.

Which of these groups of values plugged into the TVM Solver of a graphing calculator will give the monthly payment for a 30-year loan for $265,000 at 5.9% interest, compounded monthly? A. N=360; 1% = 5.9; PV=0; PMT=; FV=-265000; P/Y=12; C/Y=12; PMT END O B. N=30; 1% = 5.9; PV=0; PMT= ; FV=-265000; P/Y=12; C/Y=12; PMT:END O C.

The groups of values plugged into the TVM Solver of a graphing calculator will give the monthly payment for a 30-year loan for $265,000 at 5.9% interest, compounded monthly are,
N=360, 1% = 5.9; PV=-265000; PMT=; FV=0; P/Y=12; C/Y=12; PMT:END.
The correct option is C.
What is compound interest rate?Compound interest is computed as interest on the principle of an account plus any accrued interest.
Compound interest can be calculated using the following formula:
x = P (1+r/n
,where x = compound interest
P = principal (the initial deposit or loan amount)
r = annual interest rate
n = the number of compounding periods per unit of time
t = the number of time units the money is invested or borrowed for
Given:
TVM Solver of a graphing calculator will give the monthly payment for a 30-year loan for $265,000 at 5.9% interest, compounded monthly.
Then,
N: The overall amount of payments. Calculating this is simple if you multiply the P/Y by the number of years.
I%: Interest rate per year. Enter this rate as a percentage at all times!
Present Value, or PV: This is the sum of your investment or the loan.
PMT: The sum due.
Future Value (FV): This is your desired level of savings or, if you are calculating loans, your projected loan balance at maturity.
P/Y: The quantity of payment intervals per year.
C/Y: The quantity of compounding cycles each year.
N=360, 1% = 5.9; PV=-265000; PMT=; FV=0; P/Y=12; C/Y=12; PMT:END
Therefore, N=360, 1% = 5.9; PV=-265000; PMT=; FV=0; P/Y=12; C/Y=12; PMT:END.

Here is an inequality: -2x > 10.
1. List some values for x that would make this inequality true.
Answer: Any negative number above -5, like -6, -7, etc.
2. How are the solutions to the inequality -2x ≥ 10 different from the solutions to
-2x > 10? Explain your reasoning.
9514 1404 393
Answer:
-5 is included in the solution set of the first, but not the second
Step-by-step explanation:
The solution to -2 ≥ 10 is x ≤ -5. The solution to -2x > 10 is x < -5. The difference is that x = -5 is included in the solution set of the first inequality, but is not included in the solution set of the second inequality.
When plotted on a number line, the former inequality has a solid dot at -5, indicating that point is included. The latter inequality has an open dot (circle) at -5, indicating that point is not included. (Both plots are shaded to the left of the dot.)

3x - 5y = 3 and y = 3x2 - 4x + 1
Answer:
1,0
8/15,-7/25
Step-by-step explanation:
3x - 5y = 3
5y = 3x-3
y = (3x-3)/5
y= 3x² -4x +1
or, (3x-3)/5 = 3x²-4x +1
or, 3x-3 = 15x²-20x+5
or, 15x² - 23x +8 =0
or, 15x² - (15+8)x +8 =0
or, 15x² - 15x -8x +8 = 0
or, 15x (x - 1) -8(x-1) =0
or, (x-1)(15x-8)=0
Either,
x-1=0
x = 1
when x=1,
y= 0
or,
15x-8=0
x=8/15
when x= 8/15,
y= -7/25
