The answer to this question would be:
f(x) = 7 + 0.3x
Because 2 pounds will cost you $7, the $7 is required. If x is the number of ounces over 2 points and each ounce is 30 cents, it would only seem reasonable to multiply the ounces by 30 cents, right? Right. Therefore you add the 0.3x and you come towards the correct answer.

Step-by-step explanation:
3.3x10^7 x 5.2x10^8 3.3x5.2 x 10^7+8 17.16x10^15 = 1.716x10^16
Answer:
696.265 inches
Step-by-step explanation:
Radius = 27/2 = 13.5
2 semicircles + 2 lengths
(3.14 × 13.5²) + 2(62)
696.265 inches
Answer: 180.18
Step-by-step explanation:
Answer:Yes, it is a function
Explanation:The relation is obtained by squaring the value of x and then adding 3.
This means that the equation would be:
y = x² + 3
Now, taking a look at this equation, we would find that each value of x would have only one value of y.
Since a function is defined as a relation in which each x-value has only one y-value, therefore, the given equation represents a function.
This can be illustrated more by graphing the given relation (graph is shown in the attached image).
You will find a parabola is formed where each x value has only one corresponding y-value.
Hope this helps :)
