Answer:
A) 
B) T = -5 °C
Step-by-step explanation:
A) Let T be the change in temperature of the week. T is determined as the total temperature change (-20°C) divided by the number of weeks that have passed (4 weeks). The expression is:

B) In order to simplify the expression, simply perform the division.

This means that the temperature has dropped by 5 degrees each week.
Answer:
the correct answer will be b/c
Answer:
d. 540 deg
Step-by-step explanation:
2 pi radians = 360 deg
(360 deg)/(2pi rad) = 1
3 pi * (360 deg)/(2 pi rad) = 3 * 180 deg = 540 deg
The answer is D. y=2/3x
If you take the coordinates of each points of the line, (-3, -2) and (3, 2) and use the formula to find the slope, then putting it into formula of a line, you get
Answer:
Circumference of circle = 87.92 centimeter
Step-by-step explanation:
In the given question;
Radius of circle = 14 centimeters
Value of π = 3.14
Find:
Circumference of circle
Computation:
⇒ Circumference of circle = 2πr
where r = Radius of circle
⇒ Circumference of circle = 2(3.14)(14)
⇒ Circumference of circle = (6.28)(14)
Circumference of circle = 87.92 centimeter
