Create a function that has a derivative of f(x) = 2x + 1 at a given input value of your choice.

madreJ [45]

F(x) = (x^2) + x + C at (1,1)

1 = 1 + 1 + C

-1 = C

so,

F(x) = (x^2) + x - 1

Hey there!

First, is he used 29 out of the 547 for a park, he can't use them for two acre building lots, so we must subtract:

547-29 = 518

If we want to know how many 2 acre building lots we can sell, we can divide 518 by 2, as dividing it by 2 sees how many times 2 goes into 518- essentially how many two acre lots are in 518 acres.

This gives us 259 two-acre building lots.

Hope this helps!

A farmer sells 7.7 kilograms of apples and pears at the farmer's market.

vagabundo [1.1K]

Answer:

She sold 5.775 kilograms of pears at the farmer's market.

Step-by-step explanation:

Let's first determine the information that the question gives us, and what we need to find.

Given:

The farmer sold 7.7 kilograms of apples and pears

1/4 of the weight is apples

The rest of the weight is pears

Find:

Kilograms of pears that the farmer sold

Start by finding the fraction of the whole weight that was pears...

$1-\frac{1}{4}=\frac{4}{4}-\frac{1}{4}=\frac{3}{4}$

Now, find 3/4 of 7.7...

$\frac{3}{4}(7.7)=\frac{23.1}{4}=5.775\ kg$

She sold 5.775 kilograms of pears at the farmer's market.
