The simplified form of the exponential expression [tex]64^{\frac{1}{4} }[/tex] is [tex]2\sqrt{2}[/tex]
The given expression = [tex]64^{\frac{1}{4} }[/tex]
The exponential function is the function in the form of f(x)= [tex]a^{x}[/tex], where x is the variable and a is the constant. The constant term is the base of the exponential function.
The given expression = [tex]64^{\frac{1}{4} }[/tex]
Here we have to use the power rule of the exponents
[tex](a^{m})^{n}=a^{mn}[/tex]
To increase a number with an exponent to the power, we have to multiply the exponent times the power
We know
64 = [tex]2^{6}[/tex]
Then
[tex]64^{\frac{1}{4} }[/tex] = [tex](2^{6})^{\frac{1}{4} }[/tex]
Apply the power rule of the exponent
[tex](2^{6})^{\frac{1}{4} }[/tex] = [tex]2^{(6)(\frac{1}{4} )}[/tex]
= [tex]2^{\frac{3}{2} }[/tex]
= [tex]2\sqrt{2}[/tex]
Hence, the simplified form of the exponential expression [tex]64^{\frac{1}{4} }[/tex] is [tex]2\sqrt{2}[/tex]

A production process is checked periodically by a quality control inspector. The inspector selects simple random samples of finished products and computes the sample mean product weight. If test results over a long period of time show that of the values are over pounds and are under pounds, what are the mean and the standard deviation for the population of products produced with this process?.
The mean and the standard deviation for the population of products produced with this process are 2.0 and 0.3329
The population mean is given by
ц = [tex]\frac{L+U}{2}[/tex]
where L and U are the two given boundaries
Here, L = 1.9 and U = 2.1
⇒ ц = [tex]\frac{1.9+2.1}{2}[/tex]
⇒ ц = 2.0
Now, the z value when p =5%, from z table of probability will be
z = -1.645
Standard Deviation denoted by σ is a measure of how dispersed the data is in relation to the mean.
The Standard Deviation can be calculated by the z-score which is given as:
z = (x-ц) / (σ / [tex]\sqrt{n}[/tex])
where z is the Standard score, x is observed value, ц is mean of the sample, σ is standard deviation and n is sample size
-1.645 = (1.9 - 2.0) / (σ / [tex]\sqrt{30}[/tex])
-1.645 × (σ / [tex]\sqrt{30}[/tex]) = -0.1
1.645 × (σ / 5.477) = 0.1
σ = 0.3329
Therefore, the mean and the standard deviation for the population of products produced with this process are 2.0 and 0.3329

The ordered pair (a,b) satisfies the inequality y
The ordered pair that satisfies the inequality is (aₓ ,bₓ) .
In mathematics, an inequality is a link that compares two numbers or other mathematical expressions unfairly.
Size comparisons between two numbers on the number line are most usually made.Various types of inequalities can be represented using various notations.By definition, any monotonically growing function can be applied to both sides of an inequality without destroying their relationship (provided that both expressions are in the domain of that function). An inequality relation would be reversed if a monotonically dropping function were applied to both sides of the inequality. Examples of how to employ a monotonically declining function are the rules for the additive and multiplicative inverses for positive values.The notation a b c denotes "a b and b c," from which it also follows that a c, in accordance with the transitivity aspect discussed above. The aforementioned laws state that all three components can be changed by either adding or subtracting the same number, or by multiplying or dividing all three terms by a nonzero number, and reversing any inequalities if the number is negative. As a result, a + e + b + c is the same as a + b + e + c.Therefore we can conclude that (aₓ, bₓ) satisfies the inequality.

To pay for a home improvement project that totals $16,000, Genesis is choosing between taking out a simple interest bank loan at 8% for 3 years or paying with a credit card that compounds monthly at an annual rate of 15% for 7 years. Which plan would give Genesis the lowest monthly payment?
well, let's first check with the Bank
[tex]~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill & \$16000\\ r=rate\to 8\%\to \frac{8}{100}\dotfill &0.08\\ t=years\dotfill &3 \end{cases} \\\\\\ A=16000[1+(0.08)(3)] \implies A = 19840~\hfill \underset{monthly~payment}{\stackrel{19840~\div \stackrel{months}{36}}{\approx \text{\LARGE 551.11}}}[/tex]
now let's check with the Credit Card
[tex]~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$16000\\ r=rate\to 15\%\to \frac{15}{100}\dotfill &0.15\\ n= \begin{array}{llll} \textit{times it compounds per year} \end{array}\dotfill &12\\ t=years\dotfill &7 \end{cases}[/tex]

well, seems the Credit Card is the better deal monthly wise, though in the long run is a lot of dough.
A plan which would give Genesis the lowest monthly payment is the monthly payment on a bank loan would be $317.50.
What is simple interest?Mathematically, the simple interest earned can be calculated by using this formula:
A = P(1 + rt)
Where: A represents the future value.
P represents the principal or original value.
r represents the interest rate.
t represents the time.
Now Substituting the given parameters into the formula, we have,
A = 9000[1 + (0.09 × 3)]
A = 9000[1 + 0.27]
A = 9000 × 1.27
Future value, A = $11,430.
Next, we will calculate the monthly payment over a period of 36 months as follows:
Monthly payment = Future value/Time
Monthly payment = 11,430/36
Monthly payment = $317.50.
Similarly, we will calculate the compound interest earned on the credit card :
A = 9000[1 + (0.18/12)]⁽¹² ˣ ⁷⁾
A = 9000[1 + 0.015]⁸⁴
A = 9000 × 1.015⁸⁴
A = 9000 × 3.49258954
Future value, A = $31,433.31.
Next, we will calculate the monthly payment over a period of 84 months as follows;
Monthly payment = Future value/Time
Monthly payment = 31,433.31/84
Monthly payment = $372.21.
In this context, A plan which would give Genesis the lowest monthly payment is the monthly payment on a bank loan would be $317.50.

It takes 107 pounds of seed to completely plant an 11 acre field
How many acres can be planted per pound of seed
Answer:
0.103 acres
Step-by-step explanation:
This question tests on the concept of Conversion.
Given from the question, we know that:
107 pounds of seed = 11 acre field
To find the acres of field we can plant per pound of seed, we simply divide both sides of the equation by 107.
(107 ÷ 107) pounds of seed = (11 ÷ 107) acres of fiels
1 pound of seed = 0.103 acres of field (Rounded off to 3 significant figures)

an elliptical arch is constructed which is 6 feet wide at the base and 9 feet tall in the middle. find the height of the arch exactly 1 foot in from the base of the arch.
The height of the arch is about 6.71 feet when measured from its base at a distance of one foot.
This is further explained below.
What is an ellipse?Generally, An ellipse is a collection of points whose distances from a fixed point (focus) or fixed line (directrix) is constant and less than 1.
Depending on whether the transverse axis is horizontal or vertical, we may construct an equation for the ellipse. The main axis is located along the transverse axis. The ellipse may be represented using the following equations:
[tex]\begin{aligned}&\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1 \\&\frac{(y-k)^2}{a^2}+\frac{(x-h)^2}{b^2}=1\end{aligned}[/tex]
An elliptical arch is described as having a center height of 9 feet and a width of 6 feet. The precise height of the arch from the base has to be determined.
[tex]\frac{(y-k)^2}{a^2}+\frac{(x-h)^2}{b^2}=1[/tex]
The center (h, k) is where the graph is since we centered it at the origin (0,0). We only need to enter the numbers into the equation at this point.
[tex]\begin{aligned}\frac{(y-0)^2}{9^2}+\frac{(x-0)^2}{3^2} &=1 \\\frac{y^2}{81}+\frac{x^2}{9} &=1\end{aligned}[/tex]
Since we divided the arch in half, 0 [tex]\leq[/tex] 9 in this instance. All that is left to do is calculate the arch's height in feet from the base.
The height of 1 foot from each end of the arch must thus be determined. The locations of the arch's ends are x=-3 and x=3. Here, we have a choice between the two. We may choose x=3-1=2 for this. Therefore, all that is left to do is enter x=2 in our usual form and work out the value of y that results.
[tex]\frac{y^2}{81}+\frac{(2)^2}{9}=1[/tex]
y^2+36=81
y^2+36-36=81-36
y=3√5
Therefore, the height of the arch at 1ft from the base is 3 √5ft or approximately 6.71ft

Solve for x. Assume that lines which appear to be diameters are actual diameters.
The Answer is -6
Answer:
if x = -6, r = 180/pi and D = 360/pi
without knowing the actual D or r, one cannot truly solve for x.
Step-by-step explanation:
looking at the angle, [tex]125^o[/tex], it is part of two supplementary parts of the circle, let us call the angle between [tex]55^o\ \&\ 125^o[/tex] y. given that 125 is supplementary to y:
125+y=180
and so...
y=55
now, let us call the angle associated with the arc-length, x+76 z.
Knowing that y+55 and z are supplementary (given the length is a diameter), we can write the equation:
y + 55 + z = 180
substituting y=55 gives:
55 + 55 + z = 180
combining like terms gives:
110 + z = 180
further simplifying gives:
z = 70
x + 76 is the arc-length of the section of the circle, whose angle is now denoted by z = 70.
Arc-length = Circumference * percentage of circle
circumference is given as C = π * D OR C = 2r * π (because 2r = D)
percentage of circle is simply (number of degrees covered ÷ total degrees of a circle)
so, we have that the percentage = 70/360 [360 degrees in a circle, 70 degrees covered by the angle, z]
and the circumference is unknown without a radius or diameter length, so we will use the equation C = π * D
using the formula for arc-length:
Arc-length = π * D * 70/360
Arc-length also happens to equal x + 76, so:
x + 76 = π * D * 70/360
reduce:
x + 76 = π * D * 7/36
simplify by getting x alone:
x = π * D * 7/36 - 76
we can further simplify by creating one fraction:
[tex]x = \frac{7D\pi - 2736}{36}[/tex]
it can also be shown as:
[tex]x = \frac{7r\pi - 1368}{18}[/tex]
because, D = 2r and you could factor 2 from (7*2*r*pi - 2736) and then reduce by dividing top and bottom each by 2.
You can divide top and bottom by 2 because:
[tex]\frac{2}{36} = \frac{1}{18}[/tex]
which is because [tex]\frac{km}{ln}=\frac{k}{l} * \frac{m}{n}[/tex]
if we say km = 2 and ln = 36, then k = 2, m = 1 is the only options for k and m
and l and n can be any set of factors of 36, which include 2*18, 3*12, 6*6, 9*4.
if we choose l = 2 and n = 18, then k = l = 2 and:
[tex]\frac{k}l=\frac{2}2 = \frac{r}{r}[/tex]
which is to say that k = r = l = 2, which I only show to say generally that when k = l or you have r ÷ r, it is equal to 1.
1 * s = s
and if s = m ÷ n, then [tex]\frac{km}{ln} = \frac{m}{n}\ whenever\ k = l[/tex]
given that the answer to what is x, is -6, the arc length is therefore 70. we can plug in this 70 now to find r and therefore, D.
[tex]70 = \pi * D * \frac{70}{360}\\\\multiply\ by\ \frac{360}{70}\ on\ both\ sides\ to\ get:\\360=\pi * D\\divide\ by\ \pi\ on\ both\ sides\ to\ get:\\360/\pi = D\ OR\ 180/\pi=r[/tex]
