The correct answer to this question is 6x^5. For the solution, d/dx e^(3ln(x²)). It will be d/dx x^6. So the answer will be = 6x^5. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.

(y - 2)2 = y2 – 6y + 4<br> Is this statement true or false?
trasher [3.6K]
<h3>Answer: False</h3>

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

Explanation:

I'm assuming you meant to type out

(y-2)^2 = y^2-6y+4

This equation is not true for all real numbers because the left hand side expands out like so

(y-2)^2

(y-2)(y-2)

x(y-2) .... let x = y-2

xy-2x

y(x)-2(x)

y(y-2)-2(y-2) ... replace x with y-2

y^2-2y-2y+4

y^2-4y+4

So if the claim was (y-2)^2 = y^2-4y+4, then the claim would be true. However, the right hand side we're given doesn't match up with y^2-4y+4

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

Another approach is to pick some y value such as y = 2 to find that

(y-2)^2 = y^2-6y+4

(2-2)^2 = 2^2 - 6(2) + 4 .... plug in y = 2

0^2 = 2^2 - 6(2) + 4

0 = 4 - 6(2) + 4

0 = 4 - 12 + 4

0 = -4

We get a false statement. This is one counterexample showing the given equation is not true for all values of y.

Solve the equation: \frac{2}{3}t=\frac{5}{9} (hint: reciprocal)
Aleks04 [339]

Given:

\frac{2}{3}t=\frac{5}{9}\text{ We know that the reciprocal of }\frac{2}{3}\text{ is }\frac{3}{2}\text{.}

Multiply both sides by 3/2, we get

\frac{3}{2}\times\frac{2}{3}t=\frac{3}{2}\times\frac{5}{9}

Cancel out the common multiples, we get

t=\frac{1}{2}\times\frac{5}{3}

t=\frac{1\times5}{2\times3}

t=\frac{5}{6}

The solution of the given equation is

t=\frac{5}{6}

or

t=0.8333.

98 Points! MATH SOLVING SYSTEMS OF LINEAR EQUATIONS
photoshop1234 [79]

Answer:

40 Tickets

80 Tickets

Step-by-step explanation:

To find how many tickets it will take to break even, we use the formula:

Break Even In Units = \dfrac{FixedCost}{SalesPricePerUnit-VariableCost}

Our variables are:

Fixed Cost = $200

Sales Price = $10

Variable Cost = $5

Let's plug in our values into the formula.

Break Even In Units = \dfrac{200}{10-5}

Break Even In Units = \dfrac{200}{5}

Break Even In Units = 40

So the class needs to sell a total of 40 Tickets to break even.

Since we know that it takes 40 tickets to break even a $200 Fixed cost. To make a profit of $200, we simply multiply the number of tickets sold by 2.

Number of tickets for $200 profit = 40 x 2

Number of tickets for $200 profit = 80 Tickets.

So the class needs to sell 80 Tickets to make a $200 Profit.

These ordered pairs, {(2,4) (3,6) (4,8) (5,10)}, are a function.<br><br> True<br><br> False
ki77a [65]

Answer:

True

Step-by-step explanation:

In order for a relation (a set of ordered pairs) to be considered a <em>function</em>, every value in the <em>domain</em> (the set of all the first numbers in the pair) is associated with one value in the <em>range</em> (the set of all second numbers in the pair). This is easiest to see visually. Our domain is the set {2, 3, 4, 5} and our range is the set {4, 6, 8, 10}, and we can visualize the ordered pair (2, 4) as an "arrow" starting a 2 in the domain and ending at 4 in the range. When seen this way, a relation is a function if <em>every value in the domain only has one arrow coming out of it</em>. We can see from the attached picture that the ordered pairs in the problem are a function, so this statement is true.
