Total cost + (cost per cupcake/cup of lemonade x # of cupcakes/cups of lemonade sold)

Revenue would be how much they’re charging for each cupcake/cup of lemonade x # sold

PLZ I'M BEING TIMED Which equation could have been used to create this table?

Talja [164]

Answer:

y=6x

Step-by-step explanation:

Let us assume the table is the one shown in the attachment.

We can observe the following pattern from the table:

$12=6*2$

$24=6*4$

$36=6*6$

$60=6*10$

$76=6*12$

Hence in general

$y=6*x$

Therefore the equation that could have been used to create this table is

$y=6x$

All pictures are below please help Sandi had the following problem on her math test: . She showed her work on the test as follow

Semmy [17]

Answer/Step-by-step explanation:

The basic rule of maths operation used by Sandi, is the PEMDAS Rule.

Maths operations like the one Sandi was given must follow this rule. According to the rule:

P - Parentheses, solve everything you have in the parentheses first.

E - Exponents, do the exponents.

M - Multiplication or

D - Division operation should come next.

A - Addition or

S - Subtraction comes last.

Let's apply this rule to see if Sandi rightly applied the PEMDAS Rule:

Step 1:

6*4 + 2 ÷ 2 - 7 (given)

Step 2: perform operation involving Multiplication first according to PEMDAS Rule.

24 + 2 ÷ 2 - 7 (multiplication first. I.e. 6*4 = 24)

Step 3: perform division operation next.

24 + 1 - 7 (division operation. i.e. 2÷2 = 1)

Step 4: Subtraction

24 - 6 (i.e. +1 - 7 = -6) this is where Sandi made an error.

Step 5: subtraction

24 - 6 = 18.

Sandi made a mistake in step 4 and 5. Her addition and subtraction operation was wrong. 1 - 7 = -6 not +6.

During operation like this, either subtraction or addition can come first.

Find a function f such that f '(x) = 5x3 and the line 40x + y = 0 is tangent to the graph of f.

Alex17521 [72]

The function that is a tangent to the graph of f is $f(x) = (5/4)x^4+60$

<h3>What is the concept of integral?</h3>

The definite integral can be interpreted as the resulting area of a region. In addition, it is a value in its result, that is, it does not depend on the variable x, which can be exchanged for any other variable without changing the value of the integral.

Knowing that :

40x + y = 0 is tangent of f(x)
slope of the line = -40

therefore, f'(x)|x=a = -40, so only look for a we have:

$5a^3 = -40\\a^3 = -8\\a = -2$

if, x = -2, then y = 80 (since, 40x + y = 0), therefore, f(x) passes through (-2,80), so in the equation:

$f'(x) = 5x^3\\f(x) = (5/4)x^4 + c\\80 = (5/4)(-2)^4 + c\\c = 60$

Therefore,

$f(x) = (5/4)x^4+60$
