Look online for the growth of the trunk of a tree. Estimate how much time does it take for a water oak to grow one inch in diame
lana66690 [7]

Answer:

Explained

Step-by-step explanation:

The trunk of a tree grows in two different ways, first in height and second in diameter.Usually tree grows one ring per year in diameter. So, counting the number of rings we can determine the age of a tree. Both height and diameter growth does not occur at the same rate. Tree grows more in height than in their diameter. Mature trees usually grows 1 inch in diameter every year.

Water oak gains 24 inches in height  every year and  1.5 inch growth in diameter annually, meaning if we divide 1.5 inches by 12 months we gets 0.125 inches growth monthly. So a water oak tree needs only 8 months to grow 1 inch in diameter.

F(x) = 9x + 3<br>g(x) = 3x + 1<br>Find:<br>(f/g)(x)​
igomit [66]

Answer:

<h2>(f/g)(x) = 3</h2>

Step-by-step explanation:

f(x) = 9x + 3

g(x) = 3x + 1

To find (f/g)(x) divide f(x) by g(x)

That's

(f/g)(x) =  \frac{9x + 3}{3x + 1}

Factorize f(x)

f(x) = 9x + 3 = 3(3x + 1)

So we have

(f/g)(x) =  \frac{3(3x + 1)}{3x + 1}

Simplify

We have the final answer as

<h3>(f/g)(x) = 3</h3>

Hope this helps you

The table shows a linear function. Which equation represents the function?
4vir4ik [10]

Question is not complete and so I have attached the complete question.

Answer:

C: f(x) = -½x + 4

Step-by-step explanation:

Using slope formula between 2 points, we know that;

slope; m = (y2 - y1)/(x2 - x1)

Let's consider 2 points from the table;

(0, 4) and (-4, 6)

Thus;

m = (6 - 4)/(-4 - 0)

m = 2/-4

m = -½

Now using slope intercept form equation which is y - y1 = m(x - x1), we can find the equation of the function by picking on point say (0, 4).

Thus;

y - 4 = -½(x - 0)

y - 4 = -½x

y = -½x + 4

Thus;

f(x) = -½x + 4

Solve for c<br> -40= -5c — 25
Vikki [24]

Answer:

c = 3

Step-by-step explanation:

Let's solve the problem,

→ -40 = -5c - 25

→ -5c = -40 + 25

→ -5c = -15

→ c = -15/-5

→ [ c = 3 ]

Hence, the value of c is 3.
