Look at image shown simplify expression and write answer without negative exponents please

Answers

Answer:

The expression without a negative exponent will be:

[tex]\frac{8x^{-4}y^{-8}}{-2xy^5}=-\frac{4}{x^5y^{13}}[/tex]        

Step-by-step explanation:

Given the function

[tex]\frac{8x^{-4}\:y^{-8}}{-2xy^5}[/tex]

[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{-b}=-\frac{a}{b}[/tex]

[tex]\frac{8x^{-4}\:y^{-8}}{-2xy^5}=-\frac{8x^{-4}y^{-8}}{2xy^5}\\[/tex]

[tex]\mathrm{Divide\:the\:numbers:}\:\frac{8}{2}=4[/tex]

               [tex]=-\frac{4x^{-4}y^{-8}}{xy^5}[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=\frac{1}{x^{b-a}}[/tex]

                [tex]=-\frac{4y^{-8}}{x^5y^5}[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=\frac{1}{x^{b-a}}[/tex]

  i.e.   [tex]\frac{y^{-8}}{y^5}=\frac{1}{y^{5-\left(-8\right)}}[/tex]

so the expression becomes

    [tex]\frac{8x^{-4}\:y^{-8}}{-2xy^5}=-\frac{4}{x^5y^{5-\left(-8\right)}}[/tex]      

                  [tex]=-\frac{4}{x^5y^{13}}[/tex]

Therefore, the expression without a negative exponent will be:

[tex]\frac{8x^{-4}y^{-8}}{-2xy^5}=-\frac{4}{x^5y^{13}}[/tex]

the 6th term of a GP is 2000. Find its first term if it's common ratio is 10​

Answers

so ar^  = 2000 and you told me r = 10

a(10^5) = 2000

a = 2000/100000 = 1/50

the 6th term of a GP is 2000 is 0.02 then the first term of GP is 0.02

What is a GP(Geometric Progression)?

A geometric progression, also known as a geometric sequence, is a non-zero number sequence in which each term after the first is found by multiplying the previous one by a fixed, non-zero number known as the common ratio.

Geometric Progression (GP) is a type of sequence in which each succeeding term is produced by multiplying the previous term by a fixed number known as a common ratio. This progression is also known as a pattern-following geometric sequence of numbers.

Therefore,

The general form of a GP is a, ar, ar², ar³,...., arⁿ where a is the first term and r is the common ratio.

Given r=10

6th term of a GP = 2000

We know that nth term of a GP = [tex]ar^{n-1}[/tex]

[tex]ar^5[/tex] = 2000

a × ([tex]10^5[/tex]) = 2000

a = 2000/100000

a = 1/50 = 0.02

Therefore, the first term of GP is 0.02

Allison’s cupcake and cookie budget for her party is $105. She would like to have at least 40 cupcakes and cookies combined, and would like to have at most 5 more cupcakes than cookies. If cupcakes sell for $2.50 and cookies for $1.50, which system of inequalities could help Allison determine possible numbers of cupcakes (a) and cookies (b) that she should buy? ( a ≥ 0 , b ≥ 0 )

Answers

Answer:

a + b ≥ 40

a + 5 ≤ b

2.50a + 1.50b ≤ 105

Step-by-step explanation:

We are told she would like to have at least 40 cupcakes and cookies combined.

If a is number of cupcakes and b is number of cookies, then this inequality is;

a + b ≥ 40

Secondly, we are told she would like to have at most 5 more cupcakes than cookies.

Thus, the inequality is;

a + 5 ≤ b

Lastly, we are told that cupcakes sell for $2.50 and cookies for $1.50

Thus, the inequality is;

2.50a + 1.50b ≤ 105

Finally, the 3 inequalities are;

a + b ≥ 40

a + 5 ≤ b

2.50a + 1.50b ≤ 105

The equation 12x + 15y = 120 represents the total number of t-shirts and sweatshirts bought if spend $120

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The price for t-shirts = $12 each

The price for the sweatshirt = $15 each

Let's suppose x number of t-shirts and y number of sweatshirts bought.

Then,

12x + 15y = 120

The equation represents the total number of t-shirts and sweatshirts bought if spend $120

Thus, the equation 12x + 15y = 120 represents the total number of t-shirts and sweatshirts bought if spend $120

Answer:  AD = 9cm

Step-by-step explanation: This is a 30-60-90 triangle, so the hypotenuse is equal to twice the length of the short side of the right angle.

BC is the short side of the large triangle, so AB, the hypotenuse of the large triangle is 2×6, 12 cm

BC is also the hypotenuse of the small triangle, ΔBCD, so it is twice the length of BD, to that makes BD = 6/2= 3

Subtract BD from AB.  

That's 12 - 3  = 9 the length of AD

Answers

mark as brainlist pls, answer:

She should choose plan 1 because it is cheaper even in the long run.

plan 1: 34.99 x 12 = 419.88

plan 2: 134.97 x 4 = 539.88

-

419.88 < 539.88

Answer:

Work shown below!

Step-by-step explanation:

1 year = 12 months

Plan 1 = $34.99 per month

Plan 2 = $134.97 per 3 months

Plan 1: $34.99(12) = $419.88

Plan 2: $134.97(4) = $539.88

She would save $120 if she chooses Plan 1
