It's a rational number. 9 is a perfect square. What you have asked is written as -sqrt(9), which can be written as -sqrt(3*3) which is - 3. That's perfectly OK. What would not be OK is something like -sqrt(10) which is irrational because it cannot be represented as a fraction or a whole number or a repeating decimal or a decimal that terminates.

dem82 [27]

Answer: 3 pounds

Step-by-step explanation:

The equation can be set up according to slope form: y=mx+b where x represents cost per round.

$70 = $7.51x + $47.47

Subtract 47.47 to both sides: $22.53 = $7.51x

Divide both sides by 7.51: 3 = x

The yield of strawberry plants depends on the amount of fertilizer fed to the plants. Agricultural research shows that an acre o
andre [41]

Answer:

657 pounds

Step-by-step explanation:

Given

Represent the amount of fertilizer with x and the yield with y.

So, we have:

(x_1,y_1) = (70,630)

(x_2,y_2) = (100,900)

Required:

Determine the yield (y) when fertilizer (x) is 73ft^3

Using linear interpolation, we have:

y = y_1 + (x - x_1)\frac{(y_2 - y_1)}{(x_2 - x_1)}

Substitute the x and y values using

(x_1,y_1) = (70,630) and (x_2,y_2) = (100,900);

We have:

y = y_1 + (x - x_1)\frac{(y_2 - y_1)}{(x_2 - x_1)}

y = 630 + (x - 70)\frac{(900 - 630)}{(100 - 70)}

y = 630 + (x - 70)\frac{270}{30}

y = 630 + (x - 70)*9

Open bracket

y = 630 + 9x - 630

y = 9x - 630+630

y = 9x

To solve for y when x = 73.

We simply substitute 73 for x

y = 9x

y = 9 * 73

y = 657

<em>Hence, the yield for 73 cubic feet is 657 pounds</em>
