Answer:
Use order of operations,
1. 4^5 = 1024
2. 4^3 = 64
3. 4^2 = 16
4. 1024 * 64 = 65,476
5. 65,476 * 16 = 696,616
6. 16 * 4 = 64
7. 64 * 16 = 1,024
8. 696,616 / 1,024 = 680.2890625
Evaluate the finite geometric series. 3 + 4.5 + 6.75 + … + 34.171875
First determine the common ratio between consecutive terms.
4.5/3 = 9/6 = 3/2
6.75/4.5 = 27/18 = 3/2
and so on. The [tex]n[/tex]-th term in the sequence is given by
[tex]a_n = 3 \cdot \left(\dfrac32\right)^{n-1}[/tex]
Solve for [tex]n[/tex] that gives the last term to find how many terms are in the sum.
[tex]n = 1 + \log_{3/2}\left(\dfrac{a_n}3\right)[/tex]
Plug in the last term.
[tex]n = 1 + \log_{3/2} \left(\dfrac{34.171875}3\right) = 1 + 6 = 7[/tex]
Then the sum of the first 7 terms of this sequence is
[tex]\displaystyle \sum_{n=1}^7 3 \cdot \left(\frac32\right)^{n-1} = 3\cdot\frac{1 - \left(\frac32\right)^7}{1-\frac32} = \boxed{\frac{6177}{44}} = 96.515625[/tex]
where we use the formula
[tex]\displaystyle \sum_{n=1}^k r^{n-1} = \frac{1-r^n}{1-r}[/tex]

Write the set in set-builder notation.
1) The set of all calculus books
The set-builder form is { x | x is a calculus book}.
A set is a collection of quantities based on a specific criteria. A set can be expressed in two forms.
We usually use the form {a, b, c,....} in which we include each element of the set separated with a comma in between. This form of set notation is called the roster form.
Another set notation is the set-builder form. This form is more concise and precise and easily understandable also. In this form, all the elements are included in the set which has a same property. That is, here we don't write each and every element separately in the set but just emphasize the property of the elements which are included in the set.

Write the equation of the line that passes through the given points.
(0, 1) and (2, 2)
The equation of the line passing through points (0,1) and (2,2) will be y = ( 1 / 2) x + 1
What is an equation of the line?
An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope= 2-1 / 2-0 = 1 /2
Now pick one of the points and put in for y and x use (2,2).
2= 1/2(2) +b
2=1 + b
2-1 =1-1 +b subtract 1 from each side
1 = b This is your y-intercept
The equation will be written as:-
y = ( 1 / 2) x + 1

¿Como calcular la mitad del número?Definamos la variable "x" como el número de la ecuación.
Tenemos la oración matematica:
"La cuarta parte de un número, disminuida en 17, es igual a 4"
Esto se puede escribir como la ecuacion:
(1/4)*x - 17 = 4
Esto es una ecuación lineal que puede ser resuelta para x.
(1/4)*x - 17 = 4
(1/4)*x = 4 + 17 = 19
x = 4*19 = 76

Answer:
Equation: 2x +2x +x -8= 4(x +2)
x= 16
Step-by-step explanation:
The perimeter is the total length of the sides of a particular shape or figure.
Given that the triangle and square have an equal perimeter,
Perimeter of triangle= perimeter of square
Since a square has 4 equal sides,
2x +2x +x -8= 4(x +2)
Let's solve the above equation.
Simplify and expand:
5x -8= 4x +8
Move x terms to the left of the equation, constants to the right.
5x -4x= 8 +8
x= 16
Thus, the value of x is 16.

Answer:
x = 16
Step-by-step explanation:
The perimeter of a two-dimensional shape is the distance all the way around the outside.
As the sides of a square are equal in length, the perimeter of a square is four times the length of one side.
[tex]\begin{aligned}\implies \textsf{Perimeter of the square}&=4(x+2)\\& = 4x+8\end{aligned}[/tex]
[tex]\begin{aligned}\implies \textsf{Perimeter of the triangle}&=2x+2x+(x-8)\\&=4x+x-8\\&=5x-8\end{aligned}[/tex]
If the perimeter of the triangle and the perimeter of the square are equal then:
[tex]\begin{aligned}\implies\textsf{Perimeter of the triangle}&=\textsf{Perimeter of the square}\\5x-8&=4x+8\\5x-8-4x&=4x+8-4x\\x-8&=8\\x-8+8&=8+8\\x&=16\end{aligned}[/tex]
Therefore, the value of x is 16.
2. The area of the base of the cone is 64π cm2 and the altitude is 6 cm. Calculate the cone: (a) the length of the constituent;(b) the area of the lateral area of the cone; c) the volume.
Answer: We have to calculate the (i) volume and (ii) the surface area of the cone:
[tex]\begin{gathered} A=\pi r^2+\pi rl\rightarrow(1) \\ \\ V=\pi r^2\frac{h}{3}\rightarrow(2) \end{gathered}[/tex]The formula (1) is for the lateral surface of the cone and the formula (2) is for the volume of the cone, the unknowns are determined as follows:
[tex]\begin{gathered} r=\sqrt{\frac{64\pi}{\pi}}=8cm \\ \\ r=8cm \\ \\ l=\sqrt{r^2+h^2}=\sqrt{(8cm)^2+(6cm)^2} \\ \\ l=\sqrt{100}=10 \\ \\ l=10 \end{gathered}[/tex]Therefore the volume and the lateral surface area is calculated as follows:
[tex]\begin{gathered} \begin{equation*} A=\pi r^2+\pi rl \end{equation*} \\ \\ A=\pi(8)^2+\pi(8)(10) \\ \\ A=144\pi cm^2\Rightarrow(x) \\ \\ \begin{equation*} V=\pi r^2\frac{h}{3} \end{equation*} \\ \\ V=\pi(8cm)^2\frac{6cm}{3} \\ \\ V=128\pi cm^3\Rightarrow(y) \end{gathered}[/tex]Therefore x and y are the answers.

This is 2.Dotty and Lionel are making a graph comparing a car's age with its gasmileage. Dotty says the graph should show discrete points because the car'sage is stated in whole numbers of years. Lionel says they should make acontinuous line because age increases gradually, like time. Which student doyou agree with and why?
Lionel should be the correct answer.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Dotty and Lionel are making a graph comparing a car's age with its gas mileage.
Dotty says the graph should show discrete points because the car sage is started in whole numbers of years.
Lionel says they should make a continuous line because age increases gradually, like time.
Now,
Clearly, The Lionel is correct because when we talk about the age, that means time and Time is continuous , never stopping or slowing down for anyone.

If EFGH is a parallelogram, what is the value of x?F(4-2)340HGA. 82B. 30.5cC. 36D. 37E. 34F. 9
x = 36° (option C)
Explanation:The adjacent angles in a parallelogram are supplementary. This means the sum of the angles is equal to 180 degrees
The adjacent angles in this paralllelogram are (4x + 2)° and 34°
(4x + 2)° + 34° = 180°
4x + 2 + 34 = 180
4x + 36 = 180
4x = 180 - 36
4x = 144
Divide both sides by 4:
4x/4 = 144/4
x = 36° (option C)

The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠K is 168° so option (A) is correct.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are 3 sides and three angles in every triangle, some of which may be the same.
It is known that the sum of all three angles inside a triangle will be 180°.
So, m∠J + m∠L + m∠K = 180°
m∠K = 180° - 78° - 90°
m∠K = 12°.
The exterior angle of k = 180- 12 = 168°.
Hence "The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠K is 168°".
