Answer:
The graph of the f(x) will horizontal shift left by 3 when f(x) is replaced by f(x+3).
Step-by-step explanation:
We know that when we add a constant to the input of the parent function, we get a horizontal shift.
The direction of shifting depends upon the value of the added constantly. If the added constant is negative, the shift of the graph will be left and if the added constant is positive, the shift of the graph will be right.
For example, consider the function
f(x)
so adding in the put i.e.
would be a change on the inside of the function, giving a horizontal shift left by 3.
Therefore, the graph of the f(x) will horizontal shift left by 3 when f(x) is replaced by f(x+3).
Corresponding parts of similar triangles are proportional (CPSTP) is the property used here. Since the triangles are isosceles, then each non-base side is the same. The larger/left triangle has both sides of 215 meters and the smaller/right triangle has both sides of 43.
Let's make a proportion. On the tops are the sides, on the bottoms are the bases. On the left is the larger triangle, on the right is the smaller triangle. Keeping the pieces straight is what makes the proportion work.
To solve for x we can cross multiply.
215(x) = (230)(43)
215x = 9890
x = 46 after dividing both sides by 215
Thus the proportion is and the base is 46 meters.
