For this case, the first thing we must do is define variables.
We have then:
c: temperature in degrees celsius
f: temperature in Fahrenheit
The generic equation of the line is:
Where, the slope is given by:
Substituting values:
Rewriting:
We choose an ordered pair:
Substituting values in the generic equation:
Rewriting:
Answer: An equation of the line in slope-intercept form is: See attached image.
45.....................................................
H(t) = 0 for t = 7 and for t = -2.
It is reasonable for the time to be positive, 7 seconds.
(The offered answers all appear to be negative, so none are reasonable.)
Answer:
36 Square Yards
Step-by-step explanation:
The Scale Drawing uses a ratio
2 Inches : 3 Yards
Therefore,
1 Inch = 3/2 Yards
If the area of the scale drawing is 16 Inch²
To get the area of the actual office, we multiply by the square of the scale factor.
Scale Factor=3/2
Therefore:
The area of the actual office space
=16X(3/2)² Square Yards
=36 Square Yards
Step-by-step explanation:
perimeter=2(l+b)
18=2[(x+2)+x]
18=2(x+x+2)
18=2(2x+2)
18=4x+4
collecting like terms
18+4=4x
22=4x
dividing by 4
22/4=x
5²/4=5½
