Step-by-step explanation:
Answer:
y = 
Step-by-step explanation:
a) Let Area be the independent variable and Price of the homes sold be dependent on the area.
Let x represents the area and y represents the price.
We will plot the data in excel using trend line function.
The model so obtained is:
y =
Rounding values to the nearest hundredth, we get
y = 
you basically want to get x on it's own to find out what it equals so,
multiply both sides by 9:
x+2 = 45
take away 2 from both sides:
x = 43
Answer:
BC 4 in
Step-by-step explanation:
The steps for construction;
- Using a ruler draw line AB 4 inches and label the end points A and B
- At point A , using a protractor, measure angle 60° and mark with point. Draw a line from A passing through this point extending to a length of 4 inches
- Mark that point C.
- Using the ruler, join point C and B and measure BC.
From calculation, length BC can be found by the formula;
------where a=b=4 in , cos A = cos 60°

BC = 4 in
