B. quadratic. To determine whether a function is linear, quadratic, or exponential without graphing, examine the first, second, and third differences between the terms. If the first differences remain constant, the function is linear; if the second differences are constant, it is quadratic; if the third differences are constant, it is cubic. If the fourth differences do not remain constant, the function may be exponential. Here, the first differences are not constant, ruling out linearity. However, the second differences are constant (around $0.18 each), indicating a quadratic function. The accompanying graph supports that the points closely align with a quadratic model.
HJ is 4.0 and JE is 4.
Here's a detailed explanation: It's mentioned that H is the midpoint of GE and J is the midpoint of FE. According to the midpoint theorem, the line segment that connects the midpoints of two sides is parallel to the third side and is half its length. As JH connects these midpoints,
HJ = 1/2 (GF) and therefore the calculations show that HJ equals 8 and JE equals 4.
Response:
Four dollars or 400 cents
Detailed Explanation:
Since 2 multiplied by 10 equals 20, you can take 40 and also multiply it by 10 for the correct total.
