Answer:
Step-by-step explanation:
The formula for simple interest is
prt = I, where p is the initial investment, r is the interest rate in decimal form, t is the time it's invested for, and I is the interest earned. We multiply the p, the r, and the t together to get I. For us that looks like this:
(2.58)(.05)(4) = I and
I = .516 or 52 cents.
A rational number can be writen as a fraction.
Answer:
Yes, it will reach or exceed 141 degree F
Step-by-step explanation:
Given equation that shows the temperature T in degrees Fahrenheit x minutes after the machine is put into operation is,
Suppose T = 141°F,
Since, a quadratic equation has,
Real roots,
If Discriminant,
Imaginary roots,
If D < 0,
Since,
Thus, roots of -0.005x² + 0.45x + 125 are real.
Hence, the temperature can reach or exceed 141 degree F.
