Answer:

Step-by-step explanation:

70 is the slope.

70 represents the cost of one square foot.

Per every square foot (x), the cost increases by 70 (y).

The amount of square feet changes the total cost.

<u>Equation is represented as:</u>

<u />y=70x+3500

3500 represents the y-intercept.

70 represents the slope.

BC is tangent to circle A at B and to circle D at C. AB= 10 BC= 21 DC= 8 find AD to the nearest tenth
Andrei [34K]
The attached diagram is an interpretation of the question.
If there are other details, please post.

The distance AD is found by Pythagoras theorem, with 
AD=sqrt(BC^2+(AB-DC)^2)=sqrt(21^2+2^2)=sqrt(441+4)=sqrt(445)
=21.095 (to the third decimal place)
