The expression can be written without negative exponents as 64xy²

Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself. For example, 6 is multiplied by itself 4 times, i.e. 6 × 6 × 6 × 6. This can be written as 6⁴. Here, 4 is the exponent and 6 is the base.

Simplifying exponents is a method of simplifying the algebraic expressions involving exponents into a less complex form in a way that they cannot further be reduced. There are methods in algebra for simplifying exponents with different and same bases that we can use.

Steps to solving basic problems like this are;

Step 1

remove parentheses by multiplying factors.

Step 2

use exponent rules to remove parentheses in terms with exponents.

Step 3

combine like terms by adding coefficients.

Step 4

combine the constants.

In this case, we have an expression;

8√x²y⁴ which can be rewritten without using the square.

The compound interest earned by Evelyn in one year is $9.

Evelyn has a bank account. She deposited $90 in her account. She earns 10% interest on her deposited money. The interest earned is compounded annually. We need to calculate the interest earned by her in one year, to the nearest cent.

We need to calculate the compound interest. The formula is given below.

B = p(1 + r)^t

The variables 'B', 'p', 't', and 'r' represent the final amount, the initial amount, the time duration, and the rate of interest, respectively.

B = $90(1 + 0.1)^1

B = $90*1.1

B = $99

The final amount in her bank account after one year is $99. The interest earned is the difference between the final and the initial amount. Let the variable 'I' represent the interest earned.

I = B - p

I = $99 - $90

I = $9

Lower Limit = 24.52

Upper Limit = 36.28

Error Bound = 5.88

Lower Limit: - The Lower Limit for every class is the smallest value in that class. For example: 5 is a lower lower limit for the set S= { 5,8,42,34}

Upper Limit: - A value that is greater than or equal to every element of a set of data. For example: - { 3,5,11,20,22} is a upper bound of 22.

Given that,

Population Mean,μ = 33.2

sample Mean, χ (x bar) = 30.4

sample Size, n = 25

α (Alpha) = 0.05

Population standard deviation,σ = 15

95% confidence interval:

μ ± z critical σ / √n

Putting the values, we get,

z critical at α0.05 = ± 1.96

30.4 ±1.96( 15/√25) = 30.4 ± 5.88 = (24.52,36.28)

a) Lower Limit = 24.52

b) Upper Limit = 36.28

Using theories of Rhode island ,we got that when the British ship Gaspee ran a ground in Rhode island, the local population 1) burned it.

On June 9, Gaspee gave chase to the packet ship Hannah, but the Gaspee ran aground in shallow water on the northwestern side of  bay on what is now Gaspee Point. Her crew were unable to free her and the Dudingston decided to wait for the high tide, which would possibly set the vessel afloat. Before that could happen, however, the band of Providence men led by John Brown decided to act on a "opportunity offered of putting an end to the trouble and the vexation she daily caused."  They rowed out to the ship and boarded at the break of dawn on June 10.

The possible numbers of additional miles that Lamar can run are all the solutions of the inequality:

0 ≤ x ≤ 15

We know that Lamar will run at most 37 miles this week, and he already did run 22 miles, then the (maximum) distance left this week is:

D = 37mi - 22mi = 15mi

So he can run at most 15 miles, this means that he can run any distance between 0 miles and 15 miles by the end of the week.

So, if we define x as the distance that he will run on the week (in miles), then we can write the inequality:

0 ≤ x ≤ 15

so the possible numbers of additional miles he will run on this week are all the values of x that are a solution for the above inequality.

What is system of equation?

A system of equations in algebra consists of two or more equations and looks for common answers to the equations. "A set of equations satisfied by the same set of variables is called a system of linear equations."

Let the hours Alisa work for lawn mowing job is "x" hours and for coaching job is "y" hours.

As given in the question, Alisa can work at most 30 hours.

So the total working hours should be equal or less that 30 hours.

Therefore, the first equation can be written as:

x + y ≤ 30

And it is also given that, she needs to earn at least $240, while Her lawn mowing job pays $9 an hour, and her coaching job pays $15 for an hour.

So, Total earning = per hour earning x total hour

lawn mowing job earning = 9(x)

coaching job earning = 15(y)

Therefore, the second equation can be written as:

9x + 15y 240

Answer:

you will need to go 80 km per hr

Step-by-step explanation:

A wire is cut into two pieces, one piece bent into square and other piece will be bent into circle. Therefore, the minimum length of wire that can be used is 43 m.

The relationships between the radius of a circle and its circumference and area are :

                                           C = 2πr

                                            A = πr²

The relationships between the side length of a square and its perimeter and area are :

                                        P = 4s

                                        A = s²

So, the length of wire will be

                         W= C + P

                        W = 2πr + 4s

Subject to the constraint that the sum of areas is 144 m²:

                                 πr² + s² = 144

Using the method of Lagrange multipliers to find the extremes of wire length, we want to set the partial derivatives of the Lagrangian (L) to zero.

                       L = 2πr + 4s + λ(πr² +s² -144)

                   ∂L/∂r = 0 = 2π +2πλr      ------------------------------- (1)

                   ∂L/∂s = 0 = 4 +2λs           ------------------------------- (2)

                   ∂L/∂λ = 0 = πr² +s² -144    -------------------------------- (3)

Solving for λ, we find,

                   1 +λr = 0      ---------------------------- (4)

                ⇒  λ = -1/r      ----------------------------- (5)

Substituting into equation (2), we get,

                  4 + 2(-1/r)s = 4

               ⇒  s/r = 2  -------------------------------- (6)

This tells us the maximum wire length is that which makes the circle diameter equal to the side of the square.

Substituting the relation s=2r into the area constraint, we find,

                          πr² +(2r)² =144  

                      ⇒  r = √(144/(π+4))

                      ⇒  r= 12/√(π+4) ≈ 2.068965 . . . m

∴ The minimum wire length will be required when the entire area is enclosed by the circle. In that case,

                           πr² = 144

                        ⇒  r = √(144/π)

           and,           C = 2πr

                         = 2π√(144/π)

                         = 24√π ≈42.5388 . . m

rounding up the minimum value 42.5388... in 43.

∴ The minimum wire length will be required is 43 m
