The seed and skin of a typical avocado is about 30%-40% of the avocado's weight. for an 8 ounce avocado, how many ounces of edible fruit does it have

Step-by-step explanation:

If the seed and skin of a typical avocado is about 30%-40%, that means the edible fruit is about 60%-70%, because that would be the difference.

The answer to this problem is an interval which would expressed the range of edible fruit. In order to find the interval, we need to find the 60% and 70% of 8 ounces. Remember that, 60% is equivalent to 0.60 and 70% is equivalent to 0.70. So, the interval would be

Therefore, the edible fruit is between 4.8 ounces and 5.6 ounces.

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
