The correct answer is:  " 784 in² " . 
_________________________________________
                  {or; write as:  " 784 sq. inches " .}.
_________________________________________
      When the side is doubled (in this case, 4 is doubled; 4 * 2 = 8} ; the area is increased by 2² times; that is, by 4 times;  so, the area is:
    (196 sq. in)  * 4 =   784 sq inches .

Step-by-step explanation:

<u>Exponential Decay Function</u>

The exponential function is used to model natural decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

C(t)=C_o\cdot(1-r)^t

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The element has an initial mass of Mo=970 grams, the decaying rate is r=27.7% = 0.277 per minute.

The equation of the model is:

M(t)=M_o\cdot(1-r)^t

M(t)=970\cdot(1-0.277)^t

Operating:

M(t)=970\cdot 0.723^t

After t=13 minutes the remaining mass is:

M(13)=970\cdot 0.723^{13}

Calculating:

M(13)=14.3 gram

Which expression helps you find the length x of a side of a rectangle that has a diagonal of 15 units and a width of 9 units?
amid [387]
A. x^2 = 15^2 - 9^2

Here's why:
c^2 = a^2 + b^2

from the question:
15^2 = 9^2 + x^2

15^2 - 9^2 = x^2 which is similar to answer in A.
