B) Experiment: you imposed a treatment (new fertilizer on some plants, old on others) to determine its effect.

Answer:

B) Experiment: you imposed a treatment (new fertilizer on some plants, old on others) to determine its effect.

Step-by-step explanation:

In this situation, the fertilizer developer wants to evaluate a hypothesis, not just observe, by subjecting plants to two different treatments (new and old fertilizer) in order to determine which treatment provides a more desirable effect (more plant growth).

This process configures an experiment.

The answer is alternative B)

dan is building a circular swimming pool and wants the circumference to be no more than 95 feet what is the largest radius possi
sleet_krkn [62]

The largest radius for the swimming pool is 15.1 feet

Step-by-step explanation:

Step 1:

Circumference of the circular swimming pool built by Dan  = 95 feet

We need to determine the largest radius for the pool.

Step 2 :

Circle's circumference  is given by 2πr

Where r represents the radius

This shows that the radius is in direct proportion to the circumference. Hence the radius corresponding to the maximum circumference will be the largest possible radius

So we have 2πr = 95

=> r = \frac{95}{2\pi }  

=> r =   \frac{95}{2} × \frac{7}{22 }  where \pi  = \frac{22}{7}

=> r = 15.1 feet (rounded off to tenth of a foot)

Step 3 :

The largest radius for the swimming pool is 15.1 feet

pshichka [43]

Answer:

-x^4y + x

Step-by-step explanation:

-2x^7y^2 + 2x^4y + 2x^3y

You can take out 2x^3y because there is enough of that in each part of the equation. Then you just divide the whole numbers and subtract the exponents.

-x^4y + x
