Final answer:

The recursive definition for the given geometric sequence is an = 5an-1, with a1 = 2. Using the geometric formula to find the 10th term, we calculate the 10th term to be 3906250.

Explanation:

The given sequence is a geometric sequence, in which each term after the first is found by multiplying the previous term by a constant ratio. In this case, the ratio is obtained by dividing the second term by the first term. Therefore, the recursive formula for the given geometric sequence is an = 5 × an-1, with the first term a1 = 2.

To find the 10th term of the sequence, we use the formula: an = a1 × r(n-1), where r is the common ratio and n is the term number. Substituting the given values we get a10 = 2 × 5(10-1) = 2 × 59.

Calculating this we find that the 10th term of the sequence is 2 × 1953125 = 3906250.

The volume of the old silo is  1962.5 cubic feet, the volume of the new silo is 5298.75 cubic feet and about 3336.25 greater is the volume of the new silo than the old silo.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Mr. Macady has an old cylindrical grain silo on his farm that stands 25 feet high with a diameter of 10 feet.

h=25 feet and r =5 feet

Volume of cylinder = πr²h

=3.14×5²×25

=3.14×25×25

Volume =1962.5 cubic feet.

Now let us find the volume of new cylinder which has height 30 feet and diameter is 15 feet

Radius =15/2

r=7.5

Volume = 3.14× (7.5)² × 30

=3.14×56.25× 30

V=5298.75 cubic feet

Now let us find how much the new volume of silo is greater than old silo.

Difference = 5298.75 - 1962.5

=3336.25

Hence, the volume of the old silo is  1962.5 cubic feet, the volume of the new silo is 5298.75 cubic feet and about 3336.25 greater is the volume of the new silo than the old silo.

The 6th term is ( 4 / 27 ) and the recursive formula is q = 1/3.

When there is a constant between the two successive numbers in the series then it is called a geometric series.

The 6th term of the series is calculated as:-

1st term = 36

2nd term = 12

3rd term = 4

The recursive formula is,

q = 12/36 = 1/3

The 6th term is,

[tex]a_n = a_1( r )^{n-1}[/tex]

[tex]a_6=36 ( \dfrac{1}{3})^5=\dfrac{4}{27}[/tex]

Therefore, the 6th term is ( 4 / 27 ) and the recursive formula is q = 1/3.

She bought 'x' number of shirts.

The price of one shirt = 12.25 dollars.

Then total price of all shirts would be '12.25x' dollars.

Given is the shipping charge = 3.99 dollars.

Given is the total bill = 77.49 dollars.

It says no other tax would be charged on this order, so total bill would be sum of total price of all shirts and shipping charges.

Total Bill = Total price of all shirts + Shipping charges.

77.49 = 12.25x + 3.99

Hence, option D is correct i.e. 12.25x + 3.99 = 77.49

The answer is B, as they both add up to 15 feet and 4 inches

The correct answer is 58 viable solutions.

To model the given situation, we need to define variables, create inequalities, and then solve the system of inequalities.

Let x = the number of pens, and y = the number of pencils.

Given information:

- The total number of writing utensils must be less than or equal to 25.

- The number of pencils must be greater than or equal to the square of (3 less than the number of pens).

Step 1: Create the first inequality for the total number of writing utensils.

x + y ≤ 25

Step 2: Create the second inequality for the condition on the number of pencils.

y ≥ (x - 3)^2

Step 3: Solve the system of inequalities.

We can substitute different values of x into the second inequality to find the corresponding values of y.

For x = 1, y ≥ (-2)^2 = 4

For x = 2, y ≥ (-1)^2 = 1

For x = 3, y ≥ 0^2 = 0

For x = 4, y ≥ 1^2 = 1

For x = 5, y ≥ 2^2 = 4

...

Substituting these values into the first inequality, we get:

1 + y ≤ 25 (y ≥ 4)

2 + y ≤ 25 (y ≥ 1)

3 + y ≤ 25 (y ≥ 0)

4 + y ≤ 25 (y ≥ 1)

5 + y ≤ 25 (y ≥ 4)

...

Therefore, the viable solutions are:

(x, y) = (3, 0), (3, 1), (3, 2), ..., (3, 22)

(x, y) = (4, 1), (4, 2), ..., (4, 21)

(x, y) = (5, 4), (5, 5), ..., (5, 20)

There are a total of 22 + 20 + 16 = 58 viable solutions.

To solve this question we will have to make use of the triangle inequality which states that "the sum of the lengths of any two sides of a triangle must be greater than the length of the third side".

Let us now use this inequality to check Part A to Part E.

Part A: [tex] 3+4\ngtr9 [/tex] therefore, triangle is not possible

Part B: [tex] 3+6\ngtr9 [/tex] therefore, triangle is not possible

Part C: [tex] 4+5\ngtr9 [/tex] therefore, triangle is not possible

Part D: [tex] 4+6>9, 4+9>6, 6+9>4 [/tex] As all the three sides adhere to the triangle inequality, a triangle is possible with these dimensions.

Part E: [tex] 5+5>9, 5+9>5, 9+5>5 [/tex] As all the three sides adhere to the triangle inequality, a triangle is possible with these dimensions.

Thus, only Options D and E apply

This double inequality represents all numbers that are less than 0 on the number line and greater than -5, but not including 0 itself.

c) For numbers greater than -3 but less than 3:

[tex]\[ -3 < x < 3 \][/tex]

This double inequality represents all numbers that are greater than -3 on the number line and less than 3, but not including 3 itself.

Step-by-step explanation:

Cost of lectures = $7.33 per hour

Let [tex]e[/tex] the cost of the exam hours

Let [tex]w[/tex] be the cost of the workshop hours

Let [tex]l[/tex] be the cost of the lecture hours.

We know from our problem that exam hours cost twice as much as workshop, so:

[tex]e=2w[/tex] equation (1)

We also know that workshop hours cost twice as much as lecture hours, so:

[tex]w=2l[/tex] equation (2)

Finally, we also know that 3hr exams 24hr workshops  and 12hr lectures cost $528, so:

[tex]3e+24w+12l=528[/tex] equation (1)

Now, lets find the value of [tex]l[/tex]:

Step 1.  Solve for [tex]l[/tex] in equation (3)

[tex]3e+24w+12l=528[/tex]

[tex]12l=528-3e-24w[/tex] equation (4)

Step 2. Replace equation (1) in equation (4) and simplify

[tex]12l=528-3e-24w[/tex]

[tex]12l=528-3(2w)-24w[/tex]

[tex]12l=528-6w-24w[/tex]

[tex]12l=528-30w[/tex] equation (5)

Step 3. Replace equation (2) in equation (5) and solve for [tex]l[/tex]

[tex]12l=528-30w[/tex]

[tex]12l=528-30(2l)[/tex]

[tex]12l=528-60l[/tex]

[tex]72l=528[/tex]

[tex]l=\frac{528}{72}[/tex]

[tex]l=\frac{22}{3}[/tex]

[tex]l=7.33[/tex]

Cost of lectures  = $7.33 per hour
