Answer:
Rx)=1/3x^2
Step-by-step explanation:
A horizontal stretch is simply making the parabola of the parent function wider, it's kind of like changing the slope of a line to make it less steep.
In the graph, the red line is the parent function and the blue line is the horizontally stretched function. See how the blue line appears to be stretched (horizontally).
Answer:
<em>d = 3</em>
Step-by-step explanation:
Coordinate Plane
The image provided shows the four points given:
A=(2, 1), B=(5, 1), C=(7,2), D=(4,2).
It can be clearly seen the length of CD is just the difference of their x-coordinates:
CD = 7 - 4 = 3
We can also use the formula of the distance.
Given two points C(x,y) and D(w,z), the distance between them is:
d = 3
The question is incomplete. Here is the complete question:
Val rented a bicycle while she was on vacation. She paid a flat rental fee of f dollars, plus $8.50 each day. The total cost at the end of her vacation was t dollars. Let d represent the number of days Val rented the bicycle. Write an equation representing the total cost at the end of her vacation.
Answer:
Step-by-step explanation:
Given:
Flat rental fee =
Variable fee per day = $8.50
Total cost at the end vacation =
Number of days of her vacation =
Using unitary method, we can find the variable fee for 'd' days.
1 day variable fee = $8.50
Therefore, 'd' days variable fee =
Total cost at the end of her vacation can be obtained by adding the fixed rental fee and the variable fee obtained for the given number of days.
Now, total cost is given as:
Total cost = Flat rental fee + Variable fee
Substituting all the variables and framing above in the form of an equation, we get:
Therefore, the equation representing the total cost at the end of her vacation is
