Answer:

Step-by-step explanation:

if you use a graphing calculator you we see that the smaller the leading coeffient the wider the parabola.

or use a table and plug in values for y for each x

  y =        x²          5x²            15x²  

x = 1         1             5               15

x = 2        4           20              60

       y is larger for a larger  ax²   a coeffient  

       so the is more narrow for a higher coeffient

f(x) = 5x²  has the smallest coeffient so the widest parabola

if a company has 5 employees with annual saleries of $40,000, $50,000, $40,000, $60,000 and $90,000 what is the mean anulal sala
krek1111 [17]
To find the mean of something, add all the numbers then divide by the number of numbers there are. 
40,000 + 50,000 + 40,000 + 60,000 + 90,000 = 280,000
Then divide:
280,000/5 = 56,000

The mean of the annual salaries at the company is 56,000

Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)

Four friends all use $10 off coupons to buy themselves concert tickets.
eimsori [14]

Answer:

$64

Step-by-step explanation:

Since there were 4 of them and the coupons were $10 off, they saved a total of $40

To find how much they would have spent without the coupons, add 40 to 216:

216 + 40

= 256

To find the normal cost of one ticket, divide this by 4:

256/4

= 64

So, the price of one concert ticket without the coupon is $64
