Answer:
The required equation is .
Step-by-step explanation:
The equation of line cd is
Slope intercept form of a line is
Where, m is slope and b is y-intercept.
Slope of line cd is 3.
The product of slopes of two perpendicular lines is -1.
Therefore slope of perpendicular line is .
Point slope form of a line is
Slope of perpendicular line is and line passing through the point (3,1).
Therefore the required equation is .
Answer:
400 times Greater
Step-by-step explanation:
8 x 10^4
10^4 = 10000
10000 x 8 = 80000
2 x 10^2
10^2 = 100
2 x 100 = 200
= 400
Answer: 1.08T and (1+8/100)T
Step-by-step explanation:
Given: The average temperature two Sundays ago was T degrees Celsius.
Since, last Sunday, the average temperature was 8% higher than the average temperature two Sundays ago.
⇒ The average temperature last Sunday
Since 8%=0.08
Therefore, The average temperature last Sunday
⇒ The average temperature last Sunday
⇒ The average temperature last Sunday
⇒ The average temperature last Sunday
Thus, the right option is 1.08T and (1+8/100)T.
