Winnie measured the length of her father's ranch four times and got four different distances. her measurements are shown in the table. a. to estimate the actual length, winnie first approximated each distance to the nearest hundredth. then she averaged the four numbers. using a calculator, find winnie's estimate. distance across father's ranch (km) square root of 60, 58/8, 7.3, 7 3/5 . b. winnie's father estimated the distance across his ranch to be the square root of 56 km. how does this distance compare to winnie's estimate?

(a) winnie first approximated each distance to the nearest hundredth.

7.3 = 7.33

Now we find the average of 4 numbers

=

Winnie's estimate = 7.4825

B) Winnie's father estimated the distance across his ranch to be the square root of 56 km

Winne's father estimate - Winne's estimate = 7.48331 - 7.48225= 0.00106

Winne's father estimate is 0.00106 more than winne's estimate

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
