A function f gives the number of stray cats in a town t years since the town started

Bingel [31]

Answer:

f(0) = 243 . . . cats at the start

Step-by-step explanation:

The exponential function tells you the number of cats after t years is ...

f(t) = 243(1/3)^t

When t=0, the exponential factor is 1, so the value of the function is the multiplying constant.

f(0) = 243

This means there were 243 stray cats in town when the animal control program started.

Larry claims that (14 + 12) × (8 + 12) and (14 × 12) + (8 × 12) are equivalent because they have the same digits and the same op

FromTheMoon [43]

Answer:

$(14+12)\times (8+12) > (14\times 12)+(8\times 12)$

Step-by-step explanation:

First let us evaluate the value of both the expressions.

$(14+12)\times (8+12) = 26\times 20 = 520$

$(14\times 12)+(8\times 12) = 168 + 96 = 264$

a) Hence, Larry's claim that both the expressions are equivalent is wrong.

The evaluation of the expressions have been shown above. The second expression was obtained by swapping the addition and multiplication order and that created the difference.

b) Clearly,

520 > 264

Therefore,

$(14+12)\times (8+12) > (14\times 12)+(8\times 12)$

$(14+12)\times (8+12)$ is greater by the expression $(14\times 12)+(8\times 12)$ by a value of 520 - 264 = 256.
