Answer:
D. 29
Step-by-step explanation:
∠ACE is a secant- secant angle and is measured as half the difference of the intersecting arcs, that is
∠ACE = 0.5(m AE - m BD )
= 0.5 (106 - 48)° = 0.5 × 58° = 29° → D
Finding the difference between the two temperatures, it is found that Regina is 38.7ºC degrees colder in January than in July.
----------------------------
- The mid-afternoon temperature in January is of -12.6ºC.
- In July, it is of 26.1ºC.
- The difference of the temperatures is given by:

From the difference of 38.7ºC, there are two interpretations:
- Regina is 38.7ºC degrees colder in January than in July.
- Regina is 38.7ºC degrees warmer in July than in January.

The steepness of the slope for directly proportional relationships increases as the value of the constant m (y = mx) increases. In our two speed examples, the change in steepness of slope represents the change in speed or the change in the unit rate.
Answer:

Step-by-step explanation:
<u><em>The complete question is:</em></u>
Find the equation of the line that passes through: (-5, 5), and is perpendicular to the line y = 5/9x - 4
step 1
Find the slope of the line
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
The equation of the given line is

The slope of the given line is

The opposite reciprocal is equal to
----> slope of the perpendicular line
step 2
Find the equation of the line in point slope form

we have


substitute

step 3
Convert to slope intercept form
Isolate the variable y
