Given:
The expression is:
[tex](x^2y-3)^0+x^{\frac{1}{3}}-(4x)^{\frac{1}{2}}[/tex]
To find:
The value of the given expression when [tex]x=64[/tex] and [tex]y=27[/tex].
Solution:
We have,
[tex](x^2y-3)^0+x^{\frac{1}{3}}-(4x)^{\frac{1}{2}}[/tex]
Putting [tex]x=64[/tex] and [tex]y=27[/tex], we get
[tex]=((64)^2(27)-3)^0+(64)^{\frac{1}{3}}-(4(64))^{\frac{1}{2}}[/tex]
It can be written as
[tex]=((64)^2(27)-3)^0+(4^3)^{\frac{1}{3}}-(4)^{\frac{1}{2}}(64)^{\frac{1}{2}}[/tex]
[tex]=1+4-2(8)[/tex] [tex][\because a^0=1,a\neq 0][/tex]
[tex]=5-16[/tex]
[tex]=-11[/tex]
Therefore, the value of the given expression [tex]-11[/tex] when [tex]x=64[/tex] and [tex]y=27[/tex].

Find the area of each object. Round each answer to the nearest tenth, if necessary.
Answer The small triangles each have an area of 12m^2 and the big rectangle had an area of 80m^2. This would mean that the combined area is 104m^2
Step-by-step explanation: The rectangle shape can be found by multiplying 8 by 10 to get 80m^2. The two triangles can be found by multiplying 4 (half of 8) by 6 and then dividing it by two. This would mean that the small triangles each have an area of 12.

Answer:
Step-by-step explanation:
Given equation of a straight line is,
y = -4 - 2x
Domain of the line (x) → {-3, -2, -1, 0, 1}
Therefore, range for the given set of domain will be,
Range (y) → {2, 0, -2, -4, -6}
[By substituting the value of x in the given equation we get the value of y]
Set of scatter points are,
(-3, 2), (-2, 0), (-1, -2), (0, -4), (1, -6)
Now we plot these points to get the discrete graph as attached.

Answer:
Step-by-step explanation:
c(f) = [tex]\frac{5}{9}(f-32)[/tex]
[tex]-21 = \frac{5}{9}(f-32)[/tex]
Multiply both sides by 9
-21*9 = 5(f - 32)
-189 = 5*f - 5*32
-189 = 5f - 160
Add 160 to both sides
-189 + 160 = 5f
-29 = 5f
Divide both sides by 5
-29/5 = f
f = -5.8
f = -6 °C

A cosine function has a period of 4, a maximum value of 20, and a minimum value of 0. The function is not a reflection of its parent function over the x-axis.
Which function could be the function described?
Answer:
○ [tex]\displaystyle f(x) = 10cos\:\frac{\pi}{2}x + 10[/tex]
Step-by-step explanation:
[tex]\displaystyle \boxed{f(x) = 10sin\:(\frac{\pi}{2}x + \frac{\pi}{2}) + 10} \\ \\ y = Asin(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 10 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{-1} \hookrightarrow \frac{-\frac{\pi}{2}}{\frac{\pi}{2}} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{4} \hookrightarrow \frac{2}{\frac{\pi}{2}}\pi \\ Amplitude \hookrightarrow 10[/tex]
OR
[tex]\displaystyle y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 10 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{4} \hookrightarrow \frac{2}{\frac{\pi}{2}}\pi \\ Amplitude \hookrightarrow 10[/tex]
The cosine graph in the photograph on the right is the OPPOCITE of the cosine graph in the photograph on the left, and the reason for this is because of the negative inserted in front of the amplitude value. Whenever you insert a negative in front of the amplitude value of any trigonometric equation, the whole graph reflects over the midline. Keep this in mind moving forward. Now, with all that being said, no matter how far the graph shifts vertically, the midline will ALWAYS follow.
**Moreover, both graphs have the same maximum and minimum value, but we are looking for the equation that will not reflect over the midline of [tex]\displaystyle y = 10,[/tex]which means we do NOT want a negative in front of the amplitude value, therefore we have this equation:
[tex]\displaystyle f(x) = 10cos\:\frac{\pi}{2}x + 10[/tex]
If you are having trouble figuring out which graph is which, just remember that the parent function of [tex]\displaystyle y = cos\:x[/tex]never touches the origin unless it shifts one unit south or gets reflected from somewhere. In this case, the photograph on the left touches the origin because of a reflection [negative symbol], therefore the photograph on the right matches the equation selected.
I am delighted to assist you at any time.
The correct function is,
⇒ y = 10 cos (π/2x) + 10
What is Function?A relation between a set of inputs having one output each is called a function.
Given that;
A cosine function has a period of 4.
Since, The period is 4.
Hence, The relationship between period and b (the coefficient of the independent variable of the cosine function) is, (period) =(2π/b).
Hence, We get;
⇒ 4b = 2π
⇒ b = 2π/4
⇒ b = π/2
So, Now our equation y = a cos (bx) + c becomes as;
⇒ y = 10 cos (π/2x) + 10
Thus, The horizontal center line of this cosine curve is y = 10. The maximum value of the curve is 20, which is 10 + 10, and the minimum value is 0, which is 10 - 10.

Twice the difference of a number and 2 is 7.
Answer:
9
Step-by-step explanation:
-Twice means muliply by 2
-The difference of a number and 7 means subtract a number/variable and 7.
-Is equal to 9 means =9
2(X - 7) = 9
An equation to model the number is: n - 7 x 2 = 2
To find the equation, break apart the question.
twice the difference of a number and 7 equals 2. - "Twice" means we are multiplying by 2, or x 2
twice the difference of a number and 7 equals 2. "The difference of a number and 7" means we are subtracting n - 7, and this is being multiplied by 2 so we have n - 7 x 2 so far.
twice the difference of a number and 7 equals 2. "Equals two" means the equation is equal to 2, or = 2, so our equation is n - 7 x 2 = 2.

A rectangle is a parallelogram. What is true of the diagonals of a rectangle
that is not true of the diagonals of a parallelogram, in general?
Answer:diagonals of rectangle are equal in length while diagonals of a parallelogram can be different lengths
Step-by-step explanation:
What is true of a rectangle that is not true of a parallelogram is that; the diagonals of a rectangle are equal but the diagonals of a parallelogram are not equal.
We are dealing with rectangles and parallelogram here.
Now, both rectangle and parallelogram have 4 sides respectively with 2 of the sides being equal.
Now, for a rectangle, the diagonals are always equal because all the internal angles are equal.
However, for a parallelogram, all the internal angles are not equal and as such the diagonals are also not equal.
In conclusion, what is true of a rectangle that is not true of a parallelogram is that the diagonals of a rectangle are equal but the diagonals of a parallelogram are not equal.

Answer:
The amount of money they will spend at the restaurant is $35.16
Step-by-step explanation:
From the information given in the question, we have;
The amount Jessica, Genesis, and Violet received as bill at the restaurant, X = $29.30
The amount they wished to leave as tip, T = 20% (of the bill)
Therefore, the amount of money they will spend at the restaurant, 'A', is given as follows;
A = X + T
T = 20% of X = 20/100 × X = 0.2·X
∴ A = X + 0.2·X = 1.2·X
X = $29.30
A = 1.2·X = 1.2 × $29.30 = $35.16
The amount of money they will spend at the restaurant, A = $35.16

The campus bookstore at a local university is interested in finding out whether the textbook preference and the class level (freshman, sophomore, junior, senior) of the student are associated. A random sample of 100 students is obtained, and each student in the sample is asked which textbook he or she prefers: new books, used books, or digital books. The students are also asked whether their class level is freshman, sophomore, junior, or senior.Which of the following is the appropriate test for the investigation?A. A one-sample tt-test for a population meanB. A two-sample tt-test for a difference between meansC. A chi-square goodness-of-fit testD. A chi-square test of homogeneityE. A chi-square test of independence
Answer:
The appropriate test for the investigation is;
E. A chi-square test of independence
Step-by-step explanation:
The chi-square test for independence is for the analysis of two categories from within a population to evaluate the existence of association among the different categories within the two variables
The chi-square test for independence is used for the analysis of contingency (frequency) table
Therefore, the appropriate test for the investigation in finding out (1) the textbook preference and (2) the class level of the associated student is the chi-square test of independence
