(I WILL GIVE BRAINLIEST)
LUCKY_DIMON [66]

For this case we have the following polynomial:

3x ^ 2 + 9x + 15

The standard form of the polynomial is given by:

ax ^ 2 + bx + c

Where, the axis of symmetry of the polynomial is given by the expression:

x = - \frac {b} {2a}}

In this case we have:

a = 3\\b = 9

Therefore, replacing values we have:

x = - \frac {9} {2 (3)}

Rewriting we have:

x = - \frac {9} {6}\\x = - \frac {3} {2}

Answer:

The symmetry axis of the polynomial is given by:

x = - \frac {3} {2}

option C

Henry has been typing a book report that contains 1250 words. So far he has been typing for 1/4 hour at a rate of 30 words per m
Rasek [7]

He must type the remainder of the report by rate 32 words per minute to finish it in 25 minutes

Step-by-step explanation:

The given is:

  • Henry has been typing a book report that contains 1250 words
  • He has been typing for 1/4 hour at a rate of 30 words per minutes
  • He must type the remainder of the report in 25 more minutes

We need to find his rate to finish the remaining report in 25 minutes

∵ Henry has been typing for 1/4 hour at a rate of 30 words per minute

- We must to change \frac{1}{4} hour to minutes

∵ 1 hour = 60 minutes

∴ \frac{1}{4} hour = \frac{1}{4} hour × 60 = 15 minutes

∴ He has been typing for 15 minutes at a rate of 30 words per minute

∵ The number of words has been typed = his rate × time

∴ The number of words has been typed = 30 × 15 = 450 words

∵ The  book report that contains 1250 words

- Subtract the number of words has been typed from the total

   words to find the remaining word in the book

∴ The remaining words = 1250 - 450 = 800 words

∵ He plans to finish them in 25 minutes

- Substitute the number of the remaining words and the time

   in the rule above to find his rate

∵ 800 = his rate × 25

- Divide both sides by 25

∴ His rate = 32 words per minute

He must type the remainder of the report by rate 32 words per minute to finish it in 25 minutes
