Answer:

48 people

Step-by-step explanation:

To find 20% of 60, you multiply 60 by .2 and get 12. Subtract 12 from 60, and 48 people were not wearing hats.

Function A is a quadratic function with a vertex at (3, 4) and a leading coefficient of -1 Function B has the equation y = |x +
skad [1K]

With the information given, we deduce that the parabola is

y=-(x-3)^2+4 = -(x^2-6x+9)+4 = -x^2+6x-5

Reflecting a function over the x axis means to change its sign. After the reflection, the parabola becomes

y=x^2-6x+5

And to shift down a function, you subtract the shift from the equation: the equation becomes

y=x^2-6x+5-2=x^2-6x+3

Similarly, the other function is reflected over the x axis (sign change) and shifted up 3 (add 3 to the equation):

|x+2|\mapsto -|x+2|\mapsto -|x+2|+3

In order to compute the y intercept, we simply have to evaluate the functions at x=0: for the parabola we have

y(0)=3

For the other function, we have

y(0)=-|2|+3=-2+3=1

First term is is 22 and the common difference is -13
bonufazy [111]

Answer:

a_{n} = 35 - 13n

Step-by-step explanation:

Assuming you require the n th term formula

The n th term of an arithmetic sequence is

a_{n} = a₁ + (n- 1)d

where a₁ is the first term and d the common difference

Here a₁ = 22 and d = - 13, thus

a_{n} = 22 - 13(n - 1) = 22 - 13n + 13 = 35 - 13n
