#1 The answer is B.

#2 The answer is A.

#3 D is the correct answer

#4 D is the correct answer again.

Step-by-step explanation:

#1 Simply divide 42ft by 3 1/2 ft and your answer is 12 slats

#2 Divide 10.5 by 3 and you get 3.5.

#3 Multiply $6.99 by 2 and you get 13.98. Multiply that by 107% and your answer is about 14.96.

#4 When you add up the total price, you get $15.77. When you subtract this from $20, you get $4.23.

It is vertically stretched by a factor of 200 and shifted 10 units left.

Step-by-step explanation:

When we vertically stretch the parent function f(x) by factor of k , then the new function will be :-

And when we shift the parent function p(x) to the left by m units , then the new function will be :-

Given : Parent function :

Transformed function :-

By the above description , we can say that it is vertically stretched by a factor of 200 and shifted 10 units left.
