Step-by-step explanation:

Given

[tex](-3xy^3)(5x^4y^4)[/tex]

Required

Express as [tex]Ax^my^n[/tex]

[tex](-3xy^3)(5x^4y^4)[/tex]

Expand each factor in both brackets

[tex](-3 * x * y^3) (5 * x^4 * y^4)[/tex]

Remove brackets

[tex]-3 * x * y^3*5 * x^4 * y^4[/tex]

Bring like factors together

[tex]-3 *5* x * x^4* y^3 * y^4[/tex]

[tex]-15* x * x^4* y^3 * y^4[/tex]

Apply law of indices

[tex]-15* x^{1+4}* y^{3+4[/tex]

[tex]-15* x^5* y^7[/tex]

[tex]-15x^5y^7[/tex]

Done

The expression equivalent to (-3xy^3)(5x^4y^4) in the form Ax^my^n [tex]\mathbf{=-15x^{5} y^{7}}[/tex]

Indices are algebraic expressions usually raised to a power of a given number or term.

Given that:

To express the given indices in terms of Ax^my^n, we need to open the two brackets and multiply the corresponding variables carrying the same terms.

i.e.

[tex]\mathbf{=(-3xy^3)(5x^4y^4) }[/tex]

[tex]\mathbf{=((-3\times 5)x^{1 +4}) ( y)^{3+4}}[/tex]

[tex]\mathbf{=-15x^{5} y^{7}}[/tex]

Step-by-step explanation:

I did the quiz

Have a good day :D

The statistical question is "How many pets does Alisha have at home?''.

The correct option is Question 1.

One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.

Simply expressed, a statistical question is one that is supported by data and facts.

From the given choices:

How many pets does Alisha have at home?

Here, we have to find the number of pets.

Therefore, the required phrase -is "How many pets does Alisha have at home?''

Answer:

D

Step-by-step explanation:

[tex]\frac{1}{2} = \frac{7}{14} \\[/tex]

[tex]\frac{1}{7} = \frac{2}{14}[/tex]

[tex]\frac{7}{14} + \frac{2}{14} = \frac{9}{14}[/tex]

Answer:

10.3 years

Step-by-step explanation:

The Rule of 72 is a rule used to determine the period of time it would take an investment to double at a given fixed annual rate of return. The rule of 72 helps investors to have an estimate of how long an initial investment would double. The rule of 72 is given by the formula:

t = 72 / r

where r is the annual rate of return and t is the approximate time in years required for the investment to double.

t = 72 / r

Given that r = 7%

t = 72 / r = 72 / 7 = 10.3 years

Therefore it would take 10.3 years for an investment of $5,000 earning 7% annually to double to about $10,000

It is 14/28, In its simplest form it is 1/2

Answer:

12/4 * 3 or 3 ÷ 12/4

Step-by-step explanation:

Don't worry, I got you covered.

First, you examine the words in the sentence. After you look at the key-words, which would be "12 fourths in 3." This would translate to 12/4 into 3. Here's the examples.

Start by dividing rather than multiplying for your first equation.

3 ÷ 12/4. If you want 3 to be equal to 12/4 in division, you want to take the largest number and divide it into the smaller number. In this case, the large number would be 3 while the small number would be 12/4. It still makes it correct, despite you changing the problem a bit.

This would get you the easiest way to use your division.

Finally, try making a multiplication problem. If you want there to be 3 equal to 12/4, another justification could be 12/4 * 3. This would keep the problem true, while still solving the missing equation.

Answer:

1. Yes (side angle side)

2. I don’t know for sure but I’m thinking no

3. No

Step-by-step explanation:

both angles are the same ! so

20x + 60 = 30x + 20

10x = 40

x = 4

and then substitute x back in

20(4) + 60 = 140

root square of 370

Answer:

AC = 4[tex]\sqrt{13}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

AC² + 9² = 17²

AC² + 81 = 289 ( subtract 81 from both sides )

AC² = 208 ( take the square root of both sides )

AC = [tex]\sqrt{208}[/tex] = 4[tex]\sqrt{13}[/tex] ← exact value

     ≈ 14.42 ( to 2 dec. places )

Answer:

Step-by-step explanation:

Move all terms containing b to the left, all other terms to the right. Add '81' to each side of the equation. -81 + 81 + b 2 = 0 + 81 Combine like terms: -81 + 81 = 0 0 + b 2 = 0 + 81 b 2 = 0 + 81 Combine like terms: 0 + 81 = 81 b 2 = 81 Simplifying b 2 = 81 Take the square root of each side: b = {-9, 9}

Answer:

The Vertical Line Test is used to determine whether the graph of an equation is  a function of y in terms of x.

Step-by-step explanation:

One can conduct the vertical line test can to determine whether a graph represents a function.  The reason for this is that a function has one output value for each input value. Therefore, a vertical line includes all points with a particular x value. The y value of a point where a vertical line intersects a graph represents an output for that input x value.
