9-5 skills practice solving quadratic equations by completing the square
An example of 9-5 practice question on quadratic equations by completing the square is 5x2–2x−9=0.
What are quadratic equation?This is known to be a type of algebraic expression that is based on the second degree in x. The quadratic equation often exist in a standard form such as ax2 + bx + c = 0.
To solve for 5x2–2x−9=0
Then you have to rearrange the equation into:
x2−(2/5)x−9/5=0
= x2−(2/5)x=9/5
= (x−(2/10))2−(2/5)2=9/5(here b = 2/5)
= (x−(2/10))2=46/25
Then you take the square root on both sides
= (x−(2/10))=±1.356
Therefore x=1.556 or say −1.156.

What is the number of chromosomes in the offspring?
Male and female animals differ in the number of se x chromosomes they have. A male animal carries one X chromosome which is received from his mother as well as one Y chromosome which is received from his father. However, a female animal carries two copies of the X chromosome which is one from each parent.
Now, we are told that the female giraffe has 62 chromosomes in each skin cell and as such it means that the offspring will also have 62 chromosomes in each skin cell.

drag the labels to identify the events in the generation of an action potential in order and correctly name the refractory periods.
An absolute refractory period occurs during depolarization while the relative refractory period takes place during repolarization.
What is an action potential?An action potential refers to a sudden, quick change in electrical potential (voltage) during the transmission of an impulse (signal) to a receptor, across a cellular membrane.
The order of events in the generation of an action potential include the following:
At -60 mV, graded depolarization transmits an area of excitable membrane to threshold.At +30 mV, voltage-gated sodium channels are opened for sodium ions to move into the cell. As repolarization begins, sodium channels close, voltage-gated potassium channels are opened for potassium ions to move out of the cell. Finally, both sodium and potassium channels return to their normal states as the potassium channels is closed.In conclusion, an absolute refractory period occurs during depolarization while the relative refractory period takes place during repolarization.

The smallest positive integer n so that you can avoid ever having the exact same group of three members over all 365 days is; 11
How to solve probability combination?
if we have n people and we want to do groups of 5, the total number of different combinations is:
ⁿC₅ = n!/((n - 5)!5!)
By using the Brute force method, we have;
If n = 5,
c = 5,
Thus;
C₅ = 5
If n = 6,
c = 6,
Thus;
C₅ = 6
If n = 7,
c = 7,
Thus
C₅ = 21
If n = 8,
c = 8,
Then;
C₅ = 56
Now, If n = 9,
C = 9!/((9 - 5)!5!)
C = 126
We want to find the smallest n such that c > 365. Thus, C = 126 is too small.
Let's try n = 11;
C = 11!/(6! * 5!) = 462
This is greater than 365 and so we need at least 11 members in the club.

12.3 geometric series evaluate homework and practice
The geometric series would have a uniform common ratio
The recursive definition of the geometric sequence is [tex]a_n = 4a_{n-1}[/tex] where a1 = 128
How to determine the geometric series?Assume the geometric sequence is given as:
128,32,8,2
And the question requires the recursive definition of the geometric series
Start by calculating the common ratio (r)
[tex]r = \frac{a_{n}}{a_{n-1}}[/tex]
Substitute 2 for n
[tex]r = \frac{a_2}{a_1}[/tex]
Substitute known values
[tex]r = \frac{128}{32}[/tex]
Evaluate the quotient
[tex]r = 4[/tex]
Substitute 4 for r in [tex]r = \frac{a_{n}}{a_{n-1}}[/tex]
[tex]4 = \frac{a_{n}}{a_{n-1}}[/tex]
Cross multiply
[tex]a_n = 4a_{n-1}[/tex]
Hence, the recursive definition of the geometric series is [tex]a_n = 4a_{n-1}[/tex] where a1 = 128

15.4 segment relationships in circles homework answers
The length of the segment is an illustration of intersecting chords
The value of x is x = 27/14
How to determine the length of the segment?From the complete question (see attachment), we have:
AD = 12
AE = 3
BE = 14
EC = x
Start by calculating the length of ED
ED = AD - AE
This gives
ED =12 - 3
ED =9
The value of x is then calculated as:
x * BE = AE * ED
Substitute known values
x * 14 = 3 * 9
Evaluate the product
x * 14 = 27
Divide both sides by 14
x = 27/14
Hence, the value of x is x = 27/14

Alice says she can find the area of the room by dividing
I found the complete problem.
If Alice divides it into two trapezoids, the area formula would be: A = [(a+b) / 2] * h
Trapezoid 1
A = [(7.5 + 15)/2 * 5
A = (22.5/2) * 5
A = 11.25 * 5
A = 56.25 sq. ft
Trapezoid 2
A = [(5 + 10)/2 * 7.5
A = (15/2) * 7.5
A = 7.5 * 7.5
A = 56.25 sq. ft
Total area = 56.25 + 56.25 = 112.50 sq. ft.
