The series of these numbers are arithmetic progression because every time you subtract the next term to the previous term, each difference is common (or constant), that 2 - 7 = -5, or -3 - 2 = -5.
You can use the formula of the arithmetic term, that is
an = a1 + (n - 1)d
where an = nth term, a1 = first term, n = number of terms, d = common difference
The 14th term will be
a(14th term) = 7 + (14 - 1)*(-5) = -58
Answer:
- m∠1=45 degrees
- m∠2=135 degrees
- m∠3=45 degrees
- m∠4=135 degrees
Step-by-step explanation:
Given that: 3(m∠1+m∠3) = m∠2+m∠4.
From the diagram:
- m∠1=m∠3 (Vertical Angles)
- m∠2=m∠4 (Vertical Angles)
Therefore:
3(m∠1+m∠1) = m∠2+m∠2
3(2m∠1)=2m∠2
Divide both sides by 2
3m∠1=m∠2
m∠1+m∠2=180 (Linear Postulate)
Therefore:
m∠1+3m∠1=180
4m∠1=180
Divide both sides by 4
m∠1=45 degrees
Since m∠1=m∠3
m∠3=45 degrees
Recall: m∠1+m∠2=180 (Linear Postulate)
45+m∠2=180
m∠2=180-45
m∠2=135 degrees
Since m∠2=m∠4
m∠4=135 degrees
Answer: Blue eyes are caused by a recessive allele.
Both parents had a recessive gene for blue eyes, but both parents also had a dominant gene for brown eyes. The two genes for blue eyes happened to meet each other and give the child blue eyes.
Also, put this in the biology section next time.
For point (1, -2): -2 = -1 - 1 = -2. Therefore, point (1, -2) lies on the graph of the equation.
The graph of the equation is the set of points that are solutions to the equation.
A coordinate pair on the graph of the equation is a solution to the equation.
For the point (0, -1): -1 = -(0) - 1 = 0 - 1 = -1.
Therefore, The point ( 0, −1 ) lies on the graph of the equation.
