Answer:

1586

Step-by-step explanation:

The first thing you want to do is find the min and max value of this.

You have your expression, 4i+7, which you use to plug your lowest number (1) and highest number (26) into in order to find the min and max.+

Min.: 4i+7  —>4(1)+7 = 11

Max.: 4i+7 —> 4(26)+7 = 111

Now you have your lowest and highest, you use the formula :

Sn= n (a1 + a2 /2)

** n= 26 in this case; a1 = 11; a2 = 111

Plug in your numbers:

S26 = 26 (11+111/2)

= 26(122/2)

=26(61)

=1586

How do I solve question 6 through 8?<br> Solve for me
rewona [7]

The equations of the functions are y = -4(x + 1)^2 + 2, y = 2(x - 2)^2 + 1 and y = -(x - 1)^2 - 2

<h3>How to determine the functions?</h3>

A quadratic function is represented as:

y = a(x - h)^2 + k

<u>Question #6</u>

The vertex of the graph is

(h, k) = (-1, 2)

So, we have:

y = a(x + 1)^2 + 2

The graph pass through the f(0) = -2

So, we have:

-2 = a(0 + 1)^2 + 2

Evaluate the like terms

a = -4

Substitute a = -4 in y = a(x + 1)^2 + 2

y = -4(x + 1)^2 + 2

<u>Question #7</u>

The vertex of the graph is

(h, k) = (2, 1)

So, we have:

y = a(x - 2)^2 + 1

The graph pass through (1, 3)

So, we have:

3 = a(1 - 2)^2 + 1

Evaluate the like terms

a = 2

Substitute a = 2 in y = a(x - 2)^2 + 1

y = 2(x - 2)^2 + 1

<u>Question #8</u>

The vertex of the graph is

(h, k) = (1, -2)

So, we have:

y = a(x - 1)^2 - 2

The graph pass through (0, -3)

So, we have:

-3 = a(0 - 1)^2 - 2

Evaluate the like terms

a = -1

Substitute a = -1 in y = a(x - 1)^2 - 2

y = -(x - 1)^2 - 2

Hence, the equations of the functions are y = -4(x + 1)^2 + 2, y = 2(x - 2)^2 + 1 and y = -(x - 1)^2 - 2

$17.57

Step-by-step explanation:

well she wants to buy 3 1/2 so you make it improper to, 7/2 so then you make the price of the rainbow paper scrap a fraction, so thatll be 5.02, 502/100, then multiply,

7/2x502/100

3.5x5.02
