Answer:

(examples) n = 2

n = 3

n = 4

Step-by-step explanation:

to demonstrate, all you do is select a number to represent 'n' and plug it in.

so for example, n = 2:

2(2) + 3(2) = 5(2)

4 + 6 = 10, which is true.

So first you need to find the surface area of the cake pan in the recipe:

9 times 11 + (9 times 2)2 + (2 times 11)2=99+36+44 which you can figure out yourself.

The second one is:

10 times 10+(10 times 10)2+(10 times 2)2= 100+200+40 which you can also figure out yourself.

I am guessing you cannot use the pan you have for your recipe.

Svetllana [295]

Answer:

The tag price would be 275 dollars.

Step-by-step explanation:

10% of 250.00 is 25. But the tag price is without the discount and the 250.00 is with the discount. So, if you add 25 to 250 you get 275.

The formula to find a certain number in an arithmetic sequence is an=a1+d(n−1) .

REY [17]

Answer:

(an -a1)/d +1 = n

Step-by-step explanation:

Undo what is done to n, in reverse order. When evaluating this expression, you ...

subtract 1 from n
multiply the difference by d
add a1

When you undo these, you get ...

... an -a1 = d(n-1) . . . . . . subtract a1

... (an -a1)/d = n - 1 . . . . divide by d

... (an -a1)/d +1 = n . . . . add 1

<em>Comment on answer list</em>

Please note the use of parentheses in the answer here. These identify that the difference (an -a1) is what is divided by d. None of the offered answers has these parentheses, nor are they typeset in a way that would indicate the intent to divide (an -a1) by d. As given, none of the offered answers is correct.

The cost for a company to produce a part for d days is represented by the function f(d)=275d+12,950 what does the value 12,950 r

Helga [31]

Answer:

B.) The initial cost is $12,950

Step-by-step explanation:

Given that:

$f(d)=275d+12,950$

is the function to represent the cost for a company for the production of a part for $d$ number of days.

To find:

What does the value 12,950 represent in the above cost function.

Solution:

The given function contains two parts:

1. One part is multiple of $d$ and

2. Second part is a constant.

Here, $d$ is the number of days.

As $d$ changes, the value also changes but the constant part remains the same.

Therefore, we can conclude that the initial cost for the company is $12,950.

The answer is:

B.) The initial cost is $12,950
