at 3 weeks old, a corn is 4 inches tall and at 15 weeks it is 44 inches tall. calculate the rate of change.

Mathematics
1 answer:
pochemuha3 years ago
7 0

Answer:

Im not a hundred percent sure if this is the right answer but im pretty sure it is 3.33333 repeated so the rate of change is 3 inches per week.

Step-by-step explanation:

I calculated the problem by subtracting the weeks from each other subtracting the amount of length corn has grown too. I found that the corn grew 40 inches in 12 weeks. So I divided the amount of weeks and the amount it has grown and it gave me 3.333333 repeated which makes the answer 3 inches per week. correct me if im wrong...

Hope this helps:)

Trig: Which complex number's graph is shown?
Andrei [34K]

ANSWER

2 \sqrt{2} ( \cos( \frac{7\pi}{4}   + i  \sin(  \frac{7\pi}{4} ) )

EXPLANATION

The complex number shown has coordinates (2,-2)

or

z = 2 - 2i

The modulus is

|z|  =  \sqrt{ {2}^{2}  +  {( - 2)}^{2} }

|z|  =  \sqrt{ 8} = 2 \sqrt{2}

The argument is

\theta= \tan^{ - 1} ( \frac{ - 2}{2} )

\theta= \tan^{ - 1} ( -1) =  \frac{7\pi}{4}

The polar form is

2 \sqrt{2} ( \cos( \frac{7\pi}{4}   + i  \sin(  \frac{7\pi}{4} ) )

The first option is correct.

Someone Please Help.

Hi there!

\large\boxed{f(-6) = 5}

The value of f(-6) is the y-value at the x-coordinate x = -6.

Looking at the graph, we can see that at x = -6, y = 5.

Therefore, f(-6) = 5.

I geologist note is that the land alone at fault line moved 24.8 cm over the past 175 years on average how much did the land mor
zmey [24]
First, let's establish a ratio between these two values. We'll use that as a starting point. I personally find it easiest to work with ratios as fractions, so we'll set that up:

\frac{24.8\ cm}{175\ years}

To find the distance <em>per year</em>, we'll need to find the <em>unit rate</em> of this ratio in terms of years. The word <em>unit</em> refers to the number 1 (coming from the Latin root <em>uni-</em> ); a <em>unit rate</em> involves bringing the number we're interested in down to 1 while preserving the ratio. Since we're looking for the distance the fault line moves every one year, we'll have to bring that 175 down to one, which we can do by dividing it by 175. To preserve our ratio, we also have to divide the top by 175:

\frac{24.8\ cm}{175\ years}\div  \frac{175}{175}  \approx  &#10;\frac{0.14\ cm}{1\ year}

We have our answer: approximately 0.14 cm or 1.4 mm per year

Solve the question <br>2-(-4)+(-1)-(-3)
IgorLugansk [536]
Ugh this hurts my head just looking at it, but I'll show the process.

PEMDAS

Addition before subtraction (Not that it matters here).

2 - (-4) is the same as adding 4.  This equals 6.

-1 - (-3) is the same as adding 3.  This equals 2.

Adding these two expressions together equals 8.

Showing my work...

2 - (-4) + (-1) - (-3)

6 + (-1) - (-3)

6 + 2

8
