Mrs. Beck buys 48 pieces of house siding. Each piece is 3.7 meters long. Which equation represents the best estimate for the total length of siding Mrs. Beck buys? A. 40 × 3 = 120 meters B. 40 × 4 = 160 meters C. 50 × 4 = 200 meters D. 50 × 5 = 250 meters

C. 50 × 4 = 200 meters

Step-by-step explanation:

Best Estimate involves rounding up the numbers

Mrs. Beck buys 48 pieces of house siding.

Rounding up to the nearest whole number

= 50 pieces

Each piece is 3.7 meters long.

Rounding up to the nearest whole number

= 4.0 meters long

Hence,

50 pieces × 4 meters = 200 meters

Option C is correct

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.
