2. The coordinates of ADEF are D(4, 3). E(7,3), and F(6,8). If you translate ADEF
4 units left and 3 units up, what are the
coordinates of F?

Hence, the coordinates of F =(2,11)

Step-by-step explanation:

Translation rule to move a figure with coordinates (x,y) by h units left and k units left:

Coordinates of  F = (6,8).

After translation of 4 units left and 3 units up, the coordinates of F  =

Hence, the coordinates of F =(2,11)

Given that,

The number of heating degree days can be calculated by the formula H = 65 - T, where 65 is degrees Fahrenheit, and T is the average of the high and low temperatures for the day.

Solution,

The high temperature was 51°F and the low temperature was 45°F.

Average of high and low temperatures for the day is given by :

Now using formula :

H = 65 - T

H = 65 - 48

H = 17

Hence, there are 17 heating degree days.
