What are sides of a pentagon with different sides ?
If the sides of a pentagon are not equal in measure, it is termed as an irregular pentagon. In this case, the perimeter of the pentagon can be calculated by using the basic formula, Perimeter = sum of its sides.
Given,
side 1 = 2x
side 2 = 10
side 3 = x+2
side 4 = 11
side 5 = 3x-2
Sum of all the sides of the pentagon,
2x+10+(x+2)+11+(3x-2)=63
2x+10+x+2+11+3x-2=63
6x+21=63
6x=63-21
6x=42
x=42/6
x=7

If CE bisects ZBCD and if m ZBCE = 3x - 6
and mZECD = 2x + 11, find mZBCD. Is
ZBCD acute, right, or obtuse?
Answers
Answer:
m∠BCD = 90°
∠BCD is a right angle
Step-by-step explanation:
If a ray bisects an angle, that means it divides the angle into two equal parts in measure
∵ Ray CE bisects ∠BCD
→ Means divide it into two angles BCE and ECD which equal in measures
∴ m∠BCE = m∠ECD = [tex]\frac{1}{2}[/tex] m∠BCD
∵ m∠BCE = 3x - 6
∵ m∠ECD = 2x + 11
→ Equate them to find x
∴ 3x - 6 = 2x + 11
→ Add 6 to both sides
∵ 3x - 6 + 6 = 2x + 11 + 6
∴ 3x = 2x + 17
→ Subtract 2x from both sides
∵ 3x - 2x = 2x - 2x + 17
∴ x = 17
∵ m∠BCE = [tex]\frac{1}{2}[/tex] m∠BCD
→ Substitute x in the measure of ∠BCE to find it, then use it to
find m∠BCD
∵ m∠BCE = 3(17) - 6 = 51 - 6
∴ m∠BCE = 45°
∵ 45 = [tex]\frac{1}{2}[/tex] m∠BCD
→ Multiply both sides by 2
∴ 90 = m∠BCD
∴ m∠BCD = 90°
→ The measure of the acute angle is less than 90°, the measure of
the obtuse angle is greater than 90°, and the measure of the
right angle is 90°
∴ ∠BCD is a right angle

He set the factored expressions equal to each other.
He incorrectly solved the equation x + 3 = x + 1.
Answers
Answer:
C
Step-by-step explanation:
Plz mark brainliest
The error is he set the factored expressions equal to each other(option3).
What is X-intercepts?In a graph, the point where the line or curve crosses the axis is called the intercept. If a point crosses the x-axis it is x-intercepts. If a point crosses y-axis it is y-intercepts.
For finding x-intercepts of the given function,
First we have to factorize the given equation and then find the x values .
In [tex]f(x)=x^{2} +4x+3[/tex]
When we factorize we get , (x+3) and (x+1)
i.e., x+3=0⇒x=-3, x+1=0⇒x=-1.
That is x- intercept is -1 and -3.
Instead of this step Mathieu equated x+3=x+1.
This makes an error.
Hence, the error is he set the factored expressions equal to each other.

Answers
Answer:
Angle BCD is 13 degrees
Step-by-step explanation:
Here, we want to find the measure of angle BCD
To get this, we need an appropriate diagram. The diagram can be seen in the attachment.
To find the value of BCD, we can use an important triangle theorem.
This is that the sum of opposite interior angles of a triangle equals the exterior angle.
Thus, we have that;
BCD + DBC = CDE
hence;
3x + 5 + 2x + 3 = 9x-12
5x + 8 = 9x -12
9x-5x = 8 + 12
4x = 20
x = 20/4
x = 5
So the measure of BCD will be 2(5) + 3 = 10 + 3 = 13

Suppose each stock in Andre’s portfolio has a correlation coefficient of 0.40 (rho = 0.40) with each of the other stocks. The market’s average standard deviation is approximately 20%, and the weighted average of the risk of the individual securities in the partially diversified four-stock portfolio is 39%. If 40 additional, randomly selected stocks with a correlation coefficient of 0.30 with the other stocks in the portfolio were added to the portfolio, what effect would this have on the portfolio’s standard deviation?
Answers
Answer:
Explained below.
Step-by-step explanation:
The correlation coefficient for the portfolio with each of the other stocks is 0.40.
This correlation coefficient is less than 1. This implies that the portfolio’s assets are weakly correlated with each other.
The portfolio profits from modification. Randomly selected stocks are added to the portfolio.
The correlation coefficient of these stocks with the other stocks in the portfolio is about 0.30.
Therefore adding these randomly selected stocks will decrease the portfolio’s standard deviation.
Company-specific risk in portfolio can be reduced by this diversification but systematic or market risk can’t be eliminated. Thus the risk will (σ) decrease slowly until σp reaches to the average standard deviation of returns on the market i.e. about 20 %.

Answer:
g = 1.6t
Step-by-step explanation:
Here, we want to select the equation that shows the correct relationship between g and t
We are told that after 6 seconds, we have 9.6 gallons of water
So the amount per second will be 9.6/6 = 1.6 gallons per second
So the relationship between the two will be
g = 1.6t
Where t is the time and g is the gallons
