Which of these is the smallest number & which of these is the largest number

A) D: 4.6

B) C: 5.12

Step-by-step explanation:

A) From the given options, the smallest number is 4.6 which is option D.

Due to the fact that the decimal sides from options A to the last are; 602, 620, 666..., 600.

This is because after the number 6, the remaining digits are assumed to be zero because there is no number attached again. The one that has 6 with dot above it means that it is a recurring decimal with 6. Thus, it can't be the smallest.

B) The largest is option C which is 5.12.

Because on the decimal sides, ranking from highest to lowest we have;

120, 111..., 102, 100. A number with dot on it means recurring decimal.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
