Answer:

6 hours and 45 minutes

Step-by-step explanation:

if you divide 3 hours by four songs you deduce that it take 45 minutes to record one song.

8 is double 4 so it will take 3more hours plus the 45 minutes for the ninth song.

3+3+.45= 6.45

What is the value of the leading coefficient a, if the polynomial function P(x) = a(x + b)2(x − c) has a multiplicity of 2 at th
kirill115 [55]
If the polynomial function P(x) = a(x + b)^2(x-c) has a multiplicity of 2 at the point (−1, 0) then the factor (x-(-1))=(x+1) twice enters the polynomial representation. So, you have known one part of the left side of the polynomial function that is P(x) = a(x + 1)^2(x-c).

If polynomial function passes through the point (7,0), then 0 = a(7+ 1)^2(7-c) and since a\neq 0 you have that c=7.

At last, if polynomial function passes through the point (0,-14), then -14 = a(0+ 1)^2(0-7) and -14=-7a, so a=2.
Answer: a=2.

A bakery asks 75 customers to vote for a new bagel flavor. Onion flavor receives 33 votes. Cheddar flavor receives 42 votes. Use
m_a_m_a [10]

Using proportions, it is found that:

  • The fraction that shows the proportion of customers who voted for cheddar flavor is \frac{42}{75}
  • 56% of customers voted for cheddar flavor.

  • A proportion is the <u>number of desired outcomes divided by the number of total outcomes</u>.
  • A percentage is the <u>proportion multiplied by 100%</u>.

In this question, 42 out of 75 customers voted for the cheddar flavor, hence:

p = \frac{42}{75}

That is, the fraction that shows the proportion of customers who voted for cheddar flavor is \frac{42}{75}

The percentage is:

\frac{42}{75} \times 100\% = 56\%

56% of customers voted for cheddar flavor.
