T(x)=70(.80)*+20 where x is the time in minutes and the T is the temperature in degree celsius . What is the initial temperature

Serggg [28]

Answer:

The initial temperature of the coffee was 90°C.

Step-by-step explanation:

The function representing the temperature of the coffee after <em>x</em> minutes is:

$T(x)=70\cdot(0.80)^{x}+20$

T is the temperature in degree Celsius.

The initial temperature of the coffee will be at <em>x</em> = 0.

Compute the value of T (x) at x = 0 as follows:

$T(x)=70\cdot(0.80)^{x}+20$

$T(0)=70\cdot (0.80)^{0}+20$

$=70\times 1+20\\=70+20\\=90$

Thus, the initial temperature of the coffee was 90°C.

There is a linear relationship between a car’s weight and its gas mileage. On average, a car that weighs 2400 lb gets 35 mi/gal

Semmy [17]

The required equation is
w - 2400 = (3000 - 2400)/(29 - 35) (g - 35)
w - 2400 = -100(g - 35)
w - 2400 = -100g + 3500
w + 100g = 3500 + 2400 = 5900
w + 100g = 5900
