A milloniare estimates her wealth to be $2.2×10 to the nearst million dollars. what are the lower and upper bounds for the millioniare's wealth.

Lower bound=$2.15×10

Upper bound=$2.25×10

Step-by-step explanation:

A milloniare estimates her wealth to be $2.2×10 to the nearst million dollars.

In other words, his worth is $22 to the nearst million dollars.

To find the lower bound of the millionaire's wealth, we divide the level of precision by 2 and subtract from the millionaire's wealth.

Lower bound= 22-0.5=21.5 million dollars.

To find the upper upper bound, we add half of the level of precision to her estimate.

Upper bound =22+0.5=22.5 million dollars

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
