Answer: The degree of the given polynomial is 3.

Step-by-step explanation: We are given to find the degree of the following polynomial :

$P(y)=\dfrac{5}{7}y^3+5y^2+y+1.$

We know that

The degree of a polynomial is the highest of the degrees of its individual terms with non-zero coefficients.

In the given polynomial, the highest power of the unknown variable y is 3 in the term $\dfrac{5}{7}y^3.$

Thus, the required degree of the given polynomial is 3.

Answer:

3.17x10^-3

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the

10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Miranda bought a brand-new cell phone. She noticed that the battery

Artyom0805 [142]

The function model that represents the amount of battery left after a period of time is y = 1 ₋ 10%x

Given, Miranda bought a new cell phone which is consuming battery at a rate of 5% for every half an hour.

We are required to establish a function model that depicts how much battery is remaining after a certain amount of time.

Let y represent the amount of battery left.

and x represent the number of hours.

Then 5% per half an hour = 5% × 2 = 10%

Now frame the function model:

The amount of battery left = 1 ₋ (rate percent at which battery is being consumed)(The number of hours left)

⇒ y = 1 ₋ 10%(x)

⇒ y = 1 ₋ 10%x

As a result, we obtained the function model for the battery's remaining capacity as y = 1 ₋ 10%x

Last year the debate club had 25 members. This year there are 37 members in the club. Estimate the percent change in the number

melomori [17]

Answer:

There was a 48% increase from last year.

Step-by-step explanation:

Last year the debate club had 25 members. This year there are 37 members in the club. Estimate the percent change in the number of club members.

= (37 - 25) / 25

= -12 / 25

= 0.48 or 48%

There was a 48% increase from last year.

<u>check: </u>

25 * 1.48 = 37

In his free time Gary spends 10 hours per week on the internet and 9 hours per week on video games. If Gary has 5 hours of free

cluponka [151]

Answer:

Percentage of free time Gary spends on playing video games and using internet = 54.29%

Step-by-step explanation:

Given:

Gary spends 10 hours per week on the internet.

Gary spends 9 hours per week on video games.

Gary has 5 hours free time per day.

To find the percentage of free time Gary is using to play video game and use the internet.

Solution:

Total number of hours of free time Gary has per week = $5\times 7=35$

<em>[As there are 7 days in a week so we multiply by 7]</em>

Total number of hours of free time Gary spends on playing video games and using internet per week = $10+9=19$

Percentage of free time Gary spends on playing video games and using internet per week can be calculated as :

⇒ $\frac{\textrm{Total time spent on playing video games and using internet per week}}{\textrm{Total free time in a week}}\times 100$

⇒ $\frac{19}{35}\times 100$

⇒ 54.29% (Answer)
