Answer:

$P(x) = 3x - 10$

Step-by-step explanation:

Given

$R(x) = 5x$

$C(x) = 10 + 2x$

Required

Determine $P(x) = (R - C)(x)$

In functions;

$(f - g)(x) = f(x) - g(x)$

So, we have:

$P(x) = (R - C)(x)$

$P(x) = R(x) - C(x)$

Substitute values for R(x) and C(x)

$P(x) = 5x - (10 + 2x)$

Open bracket

$P(x) = 5x - 10 - 2x$

Collect Like Terms

$P(x) = 5x - 2x- 10$

$P(x) = 3x - 10$

We have been given that a tree that measured $3\frac{3}{4}$ feet tall was planted. A hundred years later, the tree is now $25\frac{1}{2}$ feet tall. We are asked to find the number of times times is tree now taller than it was when the school first opened.

To solve our given problem, we will divide present length of tree by length of tree when it was planted as:

$25\frac{1}{2}\div 3\frac{3}{4}$

First of all we will convert mixed fractions into improper fractions.

$25\frac{1}{2}\Rightarrow \frac{25\times 2+1}{2}=\frac{50+1}{2}=\frac{51}{2}$

$3\frac{3}{4}\Rightarrow \frac{3\times 4+3}{4}=\frac{12+3}{4}=\frac{15}{4}$

$\frac{51}{2}\div \frac{15}{4}$

Now we will convert our division problem into multiplication problem by flipping the 2nd fraction as:

$\frac{51}{2}\times \frac{4}{15}$

Cancel out common factors:

$\frac{17}{1}\times \frac{2}{5}$

$\frac{17\times 2}{1\times 5}$

$\frac{34}{5}=6\frac{4}{5}$

Therefore, the tree is $6\frac{4}{5}$ is taller now than it was when the school first opened and option A is the correct choice.

Fill in the blank. Given O below, you can conclude that OH is congruent to _____.

pishuonlain [190]

Answer:

(A) OE

Step-by-step explanation:

From the given figure, it can be seen that TG and LI are the chords of the circle with center O such that TG=LI=10.4 which means that TG is congruent to LI.

Also, OE and OH gives the shortest distance(perpendicular) of the chord LI and TG respectively from center of circle O.

And, We know that "the congruent chords are equidistant from the center of a circle."

Therefore, we can conclude that, OH is congruent to OE.

Hence, option (A) is correct.
