Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r

GREYUIT [131]

Answer:

Decay
Decrease rate is 8%

Step-by-step explanation:

Given function:

y = 490(0.92)^x

The base of the exponent is 0.92. This represents a decay as 0.92 is less than 1. It would be a growth function is the base was greater than 1.

The rate of decrease is

0.92 times

Percent decrease is

(1 - 0.92)*100% = 8%

Step-by-step explanation:

a) 24.7×52.3=1291.81

On rounding off to 3 significant digits we get

1290

$\sqrt{ {42}^{2} - {28}^{2} }$

$\sqrt{1764 -784 } = \sqrt{980}$

=31.304951

On rounding off to 5 significant figures we get

=31.305

$\sqrt[3]{78} = 4.27265$

On rounding off to 2 significant figures we get

=4.3

Hence required answers

a)1290

b)31.305

c)4.3
