Using the rational exponent property, an equivalent expression for[tex]\(x^{3/4}\[/tex] can be written as[tex]\(\sqrt[4]{x^3}\).[/tex]
Explanation:The rational exponent property states that for any real number a and positive integer[tex]\(n\), \(a^{m/n} = \sqrt[n]{a^m}\)[/tex] . Applying this property to the given expression[tex]\(x^{3/4}\[/tex] ), where (m = 3) and (n = 4), we can rewrite it as [tex]\(\sqrt[4]{x^3}\)[/tex] . This is derived by taking the fourth root of [tex]\(x^3\),[/tex] which is equivalent to raising [tex]\(x^3\)[/tex] to the power of[tex]\(1/4\).[/tex]
To further understand this, consider the original expression [tex]\(x^{3/4}\).[/tex] This represents the fourth root of [tex]\(x^3\)[/tex] , as the numerator 3 indicates the power to which x is raised, and the denominator 4 indicates the root. Expressing it as [tex]\(\sqrt[4]{x^3}\)[/tex] provides a clearer representation of the same mathematical concept, emphasizing the fourth root of [tex]\(x^3\).[/tex]
In mathematical notation, the rational exponent property is a useful tool for simplifying expressions involving fractional exponents. It allows us to transform expressions between radical form and exponent form, providing flexibility in mathematical manipulations and aiding in the understanding of the underlying concepts.

a) How much edging is needed?
we know that
To find out how much edging is needed determine the circumference of the circular garden
The circumference of the circular garden is equal to
[tex]C=\pi D[/tex]
where
D is the diameter
we have
[tex]D=2.4\ m[/tex]
assume
[tex]\pi =3.14[/tex]
substitute
[tex]C=(3.14)(2.4)[/tex]
[tex]C=7.536\ m[/tex]
Part b) we know that
To find out the cost to edge the garden, multiply the length of edging plastic needed by the cost of $4.53 per meter
so
[tex](7.536\ m)(4.53\ \$/m)=\$34.14[/tex]
kimi is playing hide-and-seek with Tommy and Manuel. Tommy is hiding 12 feet south of Kimi, and Manuel is hiding due east of Tommy. If Kimi is 20 feet from Manuel, how far apart are Tommy and Manuel?
Answer:
Tommy and Manuel are 16 ft apart
Step-by-step explanation:
The locations of all three players are shown in the image below
They form a right triangle where the hypotenuse is 20 ft, and one of the legs is 12 ft. We must find the other leg.
We must use Pythagoras's theorem. Being a and b the legs of a right triangle and c its hypotenuse, then
[tex]c^2=a^2+b^2[/tex]
Knowing c and one of the legs, say b:
[tex]a^2=c^2-b^2[/tex]
Using the values c=20, b=12 we find
[tex]a^2=20^2-12^2=400-144=256[/tex]
[tex]a=\sqrt{256}=16[/tex]
So, Tommy and Manuel are 16 ft apart

At age 20 a person deposits $370 in a savings account paying 2% interest compounded quaterly.how much money will be in the account 60 years later, when he is 80 years old? Would his savings have tripled in that time?
Final answer:
After 60 years, with an initial deposit of $370 at a 2% interest rate compounded quarterly, the amount in the savings account would be approximately $996.26. This amount does not triple the initial savings, as it is less than $1110.
Explanation:
To calculate the amount of money in the savings account 60 years later with an initial deposit of $370, an interest rate of 2% compounded quarterly, we use the compound interest formula:
A = P(1 + rac{r}[tex]{n})^{nt}[/tex]
Where:
A is the amount of money accumulated after n years, including interest.
P is the principal amount (the initial amount of money).
r is the annual interest rate (decimal).
n is the number of times that interest is compounded per year.
t is the time the money is invested for in years.
In this case:
P = $370
r = 0.02 (2% as a decimal)
n = 4 (since the interest is compounded quarterly)
t = 60
So, the equation becomes:
A = 370(1 + rac{0.02}[tex]{4})^{4 imes 60}[/tex]
A = 370[tex](1 + 0.005)^{240}[/tex]
A = 370[tex](1.005)^{240}[/tex]
A = 370(2.69259) = $996.26 (rounded to two decimal places)
So, after 60 years, the amount in the account would be approximately $996.26. To check if the savings have tripled:
370 imes 3 = $1110
Since $996.26 is less than $1110, the savings have not tripled.

Final answer:
The rule for determining the cost based on the number of tickets is Cost = 30 × Tickets. Using this rule, the cost for 10 tickets is calculated to be 300 dollars.
Explanation:
The question requires us to determine a rule for the output based on the given input of tickets and then use this rule to find the cost for 10 tickets. By examining the input and output values provided, we see a consistent pattern: the cost increases by 30 dollars with each additional ticket. Given this pattern, the rule can be formulated as an algebraic expression: Cost = 30 × Tickets.
Applying this rule to an input of x tickets, the expression becomes Cost = 30 × x. To find the cost for 10 tickets, we replace x with 10: Cost = 30 × 10 = 300 dollars.
Given: g(x) = 2x2 + 3x + 10
k(x) = 2x+16
Solve the equation g(x) = 2x(x) algebraically for x, to the nearest tenth. Explain why you
shose the method you used to solve this quadratic equation.
Answer:
x = 3.576 and x = - 3.076
Step-by-step explanation:
Two functions are given to be, g(x) = 2x² + 3x + 10 and k(x) = 2x + 16.
Now, we have to solve the equation g(x) = 2k(x)
⇒ 2x² + 3x + 10 = 4x + 32
⇒2x² - x - 22 = 0
The expression in the left hand side can not be factorized and therefore we have to use Sridhar Acharya formula which gives the solutions of the equation in the form ax² + bx + c = 0 are given by
[tex]x = \frac{-b + \sqrt{b^{2} - 4ac} }{2a}[/tex] and [tex]x = \frac{-b - \sqrt{b^{2} - 4ac} }{2a}[/tex]
Therefore, the solutions of the given equation are
[tex]x = \frac{-(- 1) + \sqrt{(- 1)^{2} - 4 (2)(-22)} }{2(2)} = 3.576[/tex]
and [tex]x = \frac{-(- 1) - \sqrt{(- 1)^{2} - 4 (2)(-22)} }{2(2)} = -3.076[/tex] (Answer)
Final answer:
To solve the equation g(x) = k(x) for x, we simplify it to 2x² + x - 6 = 0 and factor it, resulting in x = 1.5 or x = -2. The method used is factoring due to the simplicity of the equation.
Explanation:
To solve the equation g(x) = k(x) algebraically for x, we set the given functions equal to each other. Given the functions g(x) = 2x² + 3x + 10 and k(x) = 2x + 16, the equation becomes 2x² + 3x + 10 = 2x + 16. To solve for x, we must first simplify the equation by moving all terms to one side and then using the quadratic formula or factoring, if possible.
Step 1: Subtract 2x and 16 from both sides to obtain the quadratic equation 2x² + x - 6 = 0.
Step 2: Factor the quadratic equation if possible. In this case, it factors to (2x - 3)(x + 2) = 0, so the possible solutions for x are x = 1.5 or x = -2.
The chosen method for solving this quadratic equation is factoring because the equation simplifies nicely and the factors are easily observable.

70th term of the arithmetic sequence -6, 5, 16, is
Answer:753
Step-by-step explanation:
The value of [tex]n^{th}[/tex] term can be calculated by,
[tex]T_{n} = a+(n-1)d\\[/tex]
where,
a = first number of the series
d = constant difference between the numbers
So, according to the question,
a = -6
d = 11
n = 70
hence, by substituting,
[tex]T_{n} = (-6)+(70-1)11\\T_{n} = 753[/tex]
Final answer:
The 70th term of the arithmetic sequence -6, 5, 16 is calculated using the formula for the nth term of an arithmetic sequence, resulting in the 70th term being 753.
Explanation:
The student is asking for the 70th term of the arithmetic sequence -6, 5, 16. In an arithmetic sequence, the difference between consecutive terms is constant. This difference is referred to as the common difference "d". The formula for finding the nth term an of an arithmetic sequence is:
an = a1 + (n - 1)d
Using the provided sequence, we can find the common difference by subtracting the first term from the second term:
d = 5 - (-6) = 11
Now, apply the formula to find the 70th term:
a70 = a1 + (70 - 1) imes d
a70 = -6 + 69 imes 11
a70 = -6 + 759
a70 = 753
Therefore, the 70th term of the given arithmetic sequence is 753.

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 3 to 5. If there were 4360 no votes, what was the total
number of votes?
total votes
Answer:
The total number of votes 6976 votes
Explanation:
We are given the ratio of yes to no votes is equal to 3 to 5 and there were total 4360 no votes.
Let no. of yes votes be equal to x
So we can write 3:5 = x:4360
total number of yes votes can be obtained by Solving for x
[tex]x = \frac{(4360\times 3)}{5}[/tex]
= 2616
Now total number of votes =
sum of total number of yes votes and total number of no votes
= 2616 + 4360
= 6976
Hence, 6976 is the total number of votes of the residents
Answer:
The total number of votes 6976 votes
Explanation:
We are given the ratio of yes to no votes is equal to 3 to 5 and there were total 4360 no votes.
Let no. of yes votes be equal to x
So we can write 3:5 = x:4360
total number of yes votes can be obtained by Solving for x

#1 Cassie and Anna went out to dinner together. Cassie paid 8 dollars more than
Anna. If Anna paid 40% of the bill, then what was the total price of the bill?
Answer:
$40
Step-by-step explanation:
Let the total bill be "x"
Now,
Anna paid 40% (40/100 = 0.4) of the bill, that means
Cassie paid 100 - 40 = 60% of the bill, that is 60/100 = 0.6
Anna paid 0.4x & Cassie paid 0.6x
Cassie's amount is 8 dollar more, so we can write:
0.6x - 8 = 0.4x
Now, we solve for x:
0.6x - 0.4x = 8
0.2x = 8
x = 8/0.2
x = 40
THe total bill is $40
