The general term for the sequence 2, 4, 8, 16, 32, . . . is
Answers
We are given
sequence is 2 , 4 , 8 ,16 , 32 , .....
Firstly , we will check whether it is geometric sequence
Checking geometric sequence:
We will find common ratio between successive terms
and then we check whether they are equal
r1=(second term)/(first term)
[tex] r_1=\frac{4}{2}=2 [/tex]
r2=(third term)/(second term)
[tex] r_2=\frac{8}{4}=2 [/tex]
r3=(fourth term)/(third term)
[tex] r_3=\frac{16}{8}=2 [/tex]
r4=(fifth term)/(fourth term)
[tex] r_4=\frac{32}{16}=2 [/tex]
we can see that all four ratios are same
[tex] r_1=r_2=r_3=r_4=2 [/tex]
so, this is geometric sequence
Calculation of general term:
We got
common ratio is
[tex] r=2 [/tex]
Let's assume
number of terms is n
first term is 2
[tex] a_1=2 [/tex]
now, we can use formula

Consider a 15-year mortgage at an interest rate of 8% compounded monthly. The amount to be mortgaged is $130,000. After the first month's payment, what is the new outstanding principal?
Answers
To find the new outstanding principal after the first month's payment on a 15-year mortgage at an 8% interest rate compounded monthly, we calculate the monthly interest and subtract it from the original principal.
Explanation:To find the new outstanding principal after the first month's payment, we need to calculate the monthly interest and subtract it from the original principal. Here are the steps:
Convert the annual interest rate to a monthly rate by dividing it by 12: 8% / 12 = 0.67%.Convert the mortgage amount to a decimal: $130,000Calculate the interest for one month: $130,000 × 0.67% = $871.67Subtract the interest from the original principal: $130,000 - $871.67 = $129,128.33Therefore, the new outstanding principal after the first month's payment is $129,128.33.

Let f(x)=81+3e−0.7x .
What is the value of f(−3) ?
Round the answer to the nearest hundredth.
Answers
Answer:
[tex]f(-3)=91.25[/tex]
Step-by-step explanation:
Given :f(x)=81+3e−0.7x
To Find: Value of f(−3)
Solution:
[tex]f(x)=81+3e−0.7x[/tex]
Putting x = -3
[tex]f(-3)=81+3e−0.7*(-3)[/tex]
[tex]f(-3)=81+3e+2.1[/tex]
[tex]f(-3)=83.1+3e[/tex]
Since the defined value of e = 2.718

Shaquira wants to create identical packages of cookies to sell, and she must use all of the cookies.
What is the greatest number of identical packages that Shaquira can make?
Answers
Answer:
2
Step-by-step explanation:
To be able to find the greatest number of identical packages that Shaquira will be able to make, we first need to find the prime factors of the Chocolate Chip Cookies and Sugar Cookies.
86 Chocolate Chip Cookies
42 Sugar Cookies
Let's take the 86 Chocolate Chip Cookies first.
[tex]86 \left \{ {{2} \atop {43}} \right.[/tex] or 86 = 2 x 43
Now let's take the Sugar Cookies.
[tex]42 \left \{ {{2} \atop {21\left \{ {{3} \atop {7}} \right. }} \right.[/tex] or
42 = 2 x 3 x 7
Now that we have the prime factors, we then look for the Greatest Common Factor between the sets of prime factors.
2 x 3 x 7 = 42
2 x 43 = 86
2 = Total number of identical packages.

A Glass paperweight has the shape of a triangular prism. The bases are equilateral triangles with side lengths of 4 inches and a height of 3.5 inches. The height of the prism is 5 inches. find the lateral area and the total surface area of the paperwork.
Answers
The lateral area of the triangular prism is 21 square inches and the total surface area is 35 square inches.
Explanation:
To find the lateral area of the triangular prism, we need to calculate the area of all three sides excluding the bases. Since the bases are equilateral triangles with side lengths of 4 inches, the area of each base is ½ × base length × height = ½ × 4 × 3.5 = 7 square inches. The lateral area is the sum of the areas of the three sides, which is 3 × 7 = 21 square inches.
The total surface area of the prism includes the bases as well. So we need to calculate the area of the two triangular bases and add it to the lateral area. The total surface area is 2 (area of base) + lateral area = 2 × 7 + 21 = 35 square inches.

The lateral area of the triangular prism is 60 square inches, and the total surface area is 74 square inches.
To find the lateral area and total surface area of a triangular prism:
Step 1: Calculate the Area of One Triangular Base
The base is an equilateral triangle with sides of 4 inches and a height of 3.5 inches. The area of an equilateral triangle is calculated using the formula:[tex]Area = \frac{1}{2}*base*height[/tex]
So the area is:[tex]Area = \frac{1}{2} *4\ in*3.5\ in = 7\ square\ inches[/tex]
Step 2: Calculate the Perimeter of the Base
The perimeter of the base is:Perimeter = 3 * side length = 3 * 4 in = 12 inches
Step 3: Calculate the Lateral Area
The lateral area of a prism is given by:Lateral Area = Perimeter * height of the prism
Therefore, the lateral area is:Lateral Area = 12 in * 5 in = 60 square inches
Step 4: Calculate the Total Surface Area
The total surface area is the sum of the lateral area and the areas of the two triangular bases:Total Surface Area = Lateral Area + 2 * Area of one baseTotal Surface Area = 60 square inches + 2 * 7 square inches = 74 square inchesThus, the lateral area and total surface area are 60 square inches and 74 square inches.

Ian is given some red licorice that is wrapped in a coil. Upon flattening the licorice, Ian discovers that the total length is 60 cm. He then cuts the licorice into two pieces so that the ratio of the lengths of the two pieces is 7:3. Each piece is then bent to form a square. What is the total area of the two squares?
Answers
1. First, let's find the ratio of the lengths.
Since the ratio is 7 to 3, we can find the length of each licorice piece by setting its proportion over 10, since that is the sum of the ratio. Thus, one licorice piece has a length of 60 * 7/10 = 42 cm and the other has a length of 60 * 3/10 = 18 cm.
2. Now, let's create our squares.
Each piece is bent to form a square. In other words, the pieces is split into 4 equal sides. Thus, we can divide our lengths by 4. The first piece of licorice made into a square has side lengths of 42/4 = 10.5 cm. The second piece of licorice has side lengths of 18/4 = 4.5 cm.
3. Finding the area of our squares.
Now, all we need to do is find the sum of the areas of the squares. The first square has an area of [tex]10.5^2 = 110.25[/tex] cm^2 and the second square has an area of [tex]4.5^2 = 20.25[/tex] cm^2. Thus, our answer is 130.5 cm^2.

The required d is the dependent variable and t is the independent variable.
What is equation?In mathematics, an equation is a statement that asserts the equality of two expressions. It typically contains one or more variables, which represent unknown values.
In the equation, d=60t, t is the independent variable and d is the dependent variable. The value of d depends on the value of t, which is the amount of time the car travels, and hence is the independent variable.
Thus, d is the dependent variable and t is the independent variable.

Step-by-step explanation:
Given: Lines a and b are parallel to each other.
To find: The measure of the angle b.
Solution: It is given that Lines a and b are parallel to each other, thus using the parallel lines properties, we have
[tex]m{\angle}a=79^{\circ}[/tex] (Vertically opposite angles)
Now, [tex]m{\angle}a[/tex] and [tex]m{\angle}b[/tex] forms the corresponding angle pair, thus they are congruent.

B) The amount of change for Troop B is 24-21=3; the original amount is 21. This gives us:
[tex]\frac{3}{21}\times 100=14.3\%[/tex]
C) Troop A gained 2 more members, while Troop B gained 3; Troop B gained more new people.
D) Since the percent of change for each troop was equal, they both had an equal record in terms of percentage of new members.
