You are buying cupcakes for a school party. They are in a package of 6 for $8.50. You have budgeted no more than $40 to spend. If cost of the cupcakes is a function of the number of packages purchased, what is the largest element of the domain in this situation?

Answers

Answer: Largest element in the domain is 4

The largest number of packages you can buy is 4

======================================================

Explanation:

1 package costs 8.50*1 = 8.50 dollars

2 packages cost 8.50*2 = 17 dollars

3 packages cost 8.50*3 = 25.50 dollars

and so on. In general

x packages cost 8.50*x = 8.50x dollars

where x is a place holder for a positive whole number (1,2,3,...)

The total amount spent is 8.50x and the budget is $40

This means,

[tex]8.50x \le 40\\\\x \le \frac{40}{8.50}\\\\x \le 4.70588\\\\x \le 4\\\\[/tex]

We round down regardless of how close we are to 5.

If x = 4, then 8.50*x = 8.50*4 = 34

While if x = 5, then 8.50*x = 8.50*5 = 42.5

So we see we go over budget if we buy x = 5 packages.

This makes x = 4 the largest in the domain.

Recall the domain is the set of allowed x inputs. In this case, x is a positive whole number (since we can't buy half a package for instance).

10000$ is invested at annual compound interest after 4 years the investment has become $11,608.86 what annual rate of compound interest was used ?

Answers

$10,000 is invested at annual compound interest. After 4 years, the investment has become $11,608.86. What annual rate of compound interest was used?

Answer: 3.8%

The annual rate of the compound interest is given as 3.8%.

What is compound interest?

Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.

Amount = principal[1 + r/n]ⁿᵃ

Principal = P rate= r Time =a  , n = compounding frequency

Here,
Amount = principal[1 + r/n]ⁿᵃ
11608.86 = 10000[1 + r/1]⁴
1.160886 = [1 + r]⁴
1 + r = 1.038
r = 1.038 - 1
r = 0.038
r% = 0.038 ×100%
r% = 3.8%

Thus, the annual rate of the compound interest is given as 3.8%.

Step-by-step explanation:

It’s 37 degrees. If you look at one straight line, both sides have to equal 180. So take 180-37 and that’s the answer to CBD. Then you take THAT and subtract it from 180, which is 37. That’s the complicated way of explaining it. Since it’s right across it’s 37.

Zoe needs to rent a car. Kara's Kar Kompany charges $22 per day and a $100 cleaning fee. Callie's Car Company charges $26 per day and has a $40 cleaning fee. After how many days would the rental cost be the same for both car rental companies?

A) 18 Days
B) 13 Days
C) 15 Days
D) 8 Days

Answers

Answer:

C) Fifteen days

Answer:

C) 15 days

Step-by-step explanation:

To answer this question, we must make an equation, so lets use the variable 'd' equal the number of days a car is being used for:

22d + 100 = 26d + 40

Now, we combine like terms:

22d + 100 = 26d + 40

-22d           -22d

100 = 4d + 40

-40            -40

60 = 4d

/4     /4

d = 15

So, the rental cost will be the same for both car companies after 15 days

Write an equation in slope intercept form with the given information.
Slope = 4 and goes through point (1,8)
(Please help me)

Answers

Answer:

y= 4x +4

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the slope and c is the y-intercept.

Given that the slope is 4, m= 4.

Substitute m= 4 into the equation:

y= 4x +c

To find the value of c, substitute a pair of coordinates.

When x= 1, y= 8,

8= 4(1) +c

8= 4 +c

c= 8 -4 (-4 on both sides)

c= 4 (simplify)

Thus, the equation is y= 4x +4.

Why is 3^-2 not a negative number?

Answers

The rule you use is x^(-k) = 1/(x^k)

In this case x = 3 and k = 2, so,

3^(-2) = 1/(3^2) = 1/9

--------------------------------------------

One way to think of it, is to consider the equation below

3^2*3^x = 1

We can solve for x like this

3^2*3^x = 1

3^(2+x) = 1

3^(2+x) = 3^0

2+x = 0 .... the bases are equal, so the exponents must be equal

x = -2

meaning that

3^2*3^x = 1

updates to

3^2*3^(-2) = 1

Now isolate the 3^(-2)

3^2*3^(-2) = 1

3^(-2) = 1/(3^2)

3^(-2) = 1/9
