Answer:

f(x)=g(x) only at x= 0 and x= 1. They are not equal at x= 3.

Step-by-step explanation:

We have the functions, f(x)=2x+1 and g(x)=2x^2+1

Substituting the values of x in the given function, we see that,

                     f(x)=2x+1                     g(x)=2x^2+1

x= 0                 f(0)= 2×0+1= 1                     g(0)= 2×(0^2)+1= 1

x= 1                  f(1)= 2×1+1= 3                      g(1)= 2×(1^2)+1= 2+1 = 3

x= 3                 f(3)= 2×3+1= 7                    g(3)= 2×(3^2)+1= 18+1 = 19

Thus, from the graphs below and the above calculations, we have,

f(x)=g(x) only at x= 0 and x= 1.

Nolan Walker decided to buy a used snowmobile since his credit union was offering such low interest rates. He borrowed $2,700 at
stealth61 [152]

Using the formula for simple interest, it is found that he paid $119.87 in interest.

The<u> simple interest formula</u> is given by:

E = PIt

  • E is the amount of interest earned.
  • P is the principal(the amount of money invested).
  • I is the interest rate(yearly, as a decimal).
  • t is the time, in years.

In this problem:

  • Borrowed $2,700, thus P = 2700
  • Interest rate of 3.5%, thus I = 0.035
  • From December 26, 2019 to February 21, 2021, there were 423 days, thus the time in years is t = \frac{423}{365} = 1.2685

Thus, the interest paid was of:

E = PIt = 2700(0.035)(1.2685) = 119.87

$119.87.
