Answer:

c. Will produce a slope field with rows of parallel tangents

Step-by-step explanation:

We can write a differential equation that is a function of y only as:

$y'=f(y)$

So the derivative, in this particular case, of any function will be a function of the dependent variable y only, it means that the curves you will get should all be pointing in the same direction for each value of x. Therefore the sketch of the slopes field would have parallel curves for each value of x, in other words, it will produce a slope field with rows of parallel tangents.

I hope it helps you!

How do you estimate 175.32 ÷ 3 =

geniusboy [140]

Answer:

≈ 58

Step-by-step explanation:

Estimation usually means you want an answer good to one or maybe two significant figures. That usually means you want to round the numbers involved to one or two significant figures.

Doing that here transforms the problem to 180/3 = 60, an answer with one significant figure.

You can improve the estimate a bit by recognizing that it is a little high (the numerator is higher than 175.32, but the denominator is the same). Since the numerator is high by about 5, the estimate is high by about 5/3 or a little less than 2. A closer estimate will be 60 - 2 = 58.

_____

The degree to which you refine the estimate will depend on the error requirements you have. Certainly an estimate of 60 is within 10% of the true value, so is "close enough" for many purposes.

What does 4 5/8 - 1 2/5 equal?

mihalych1998 [28]

$4 \frac{5}{8} - 1 \frac{2}{5} \\ \\ \frac{37}{8} - \frac{7}{5} \\ \\ \frac{185}{40} - \frac{56}{40} = \frac{185 - 56}{40} \\ \\ = \frac{129}{40} = 3.225 = 3 \frac{9}{40}$
