Answer:
Tn = 2/3^(n-1)
Step-by-step explanation:
The nth term of a geometric progression is expressed as
Tn = ar^{n-1}
a is the first term
n is the number of terms
r is t common ratio
From the sequence
a = 2/9
r = (2/3)/(2/9) = 2/(2/3) =3
Substitute
Tn = 2/9(3)^(n-1)
Tn = 2/3^(n-1)
Hence the required equation is Tn = 2/3^(n-1)
Answer:
the actual answer is [tex]a_{n}[/tex][tex]=(\frac{2}{9} )3^{n-1}[/tex]

Assume you have a balance of $1,900 on a credit card.
If the credit card has an annual interest rate of 13.6% and only the minimum monthly
payment of $35 is made, how many months will it take to pay off the credit card?
principal=$1900
rate =13.6 %
simple interest= $35
Time=?
SIMPLE INTEREST ={PRINCIPAL×RATE×TIME}/{100}
$35= [tex]{$1900 ×13.6× TIME}{100} /[/tex]

Assuming each area code is just as likely as any other, what's the probability that the area code of two back to back spam calls are 804
Complete Question:
Yanay gets a lot of spam calls. An area code is defined to be a three digit number from 200-999 inclusive. In reality, many of these area codes are not in use, but for this question we'll simplify things and assume they all are.
Assuming each area code is just as likely as any other, what's the probability that the area code of two back to back spam calls are 804?
Answer:
1/6400 or 0.0000015625
Step-by-step explanation:
Given
Area Codes = 200 to 999 (inclusive)
Required
Determine the probability that back to back calls have area code 804
[First, we need to calculate the totality of area codes]
Total Area Codes = 999 - 200 + 1
Total Area Codes = 800
The probability of each code is 1/800
So, the probability of having back to back code of 804 is:
Probability = 1/800 * 1/800
Probability = (1/800)²
Probability = 1/640000
Hence, the required probability is 1/640000 or 0.0000015625

The $99.99 digital camera Mia purchased was on sale for 15% off. What amount did Mia get off the price? please leave an explanation
Answer: Sale Price = $84.99 (answer). This means the cost of the item to you is $84.99. You will pay $84.99 for a item with original price of $99.99 when discounted 15%. In this example, if you buy an item at $99.99 with 15% discount, you will pay 99.99 - 14.9985 = 84.99 dollars.

Write the equation of the line parallel to the line y= 5x + 3 that passes through the point (3,3)
Answer:
y=5x-12
Step-by-step explanation:
y=5x+3, and just replace the x and y to get the b. The slope is the same.
1) 3=5(3)+b
2)3=15+b
3)-12=b
4) y=5x-12

Identify the pairs of alternate exterior angles in the given figure.
Question 14 options:
A)
∠3 and ∠6; ∠4 and ∠5
B)
∠2 and ∠7; ∠1 and ∠8
C)
∠3 and ∠5; ∠4 and ∠6
D)
∠1 and ∠7; ∠2 and ∠8
Answer: Choice D
Angle 1 and angle 7Angle 2 and angle 8=========================================================
Explanation:
The angles 3,4,5,6 are all considered interior angles because they are inside or between the parallel lines.
The remaining angles 1,2,7,8 are exterior angles as they outside the parallel lines. You can think of angles 3,4,5,6 being in the river or a road, while the other angles are on the sidewalk or the shoreline.
Alternating angles are ones that are on either side of the transversal cut.
Combining the two ideas leads to alternate exterior angles being outside the parallel lines and on either side of the transversal. This applies to the following pairs:
angle 1 and angle 7angle 2 and angle 8This is why choice D is the answer.

Use factoring to find the zeros of the following function:
f(x)=5x^3-7x^2-45x+63
Answer:
-3, +3, 7/5
Step-by-step explanation:
(5x³-7x²)+(-45x+63)=0
X²(5x-7)-9(5x-7)=0
(X²+9)(5x-7)=0
Either x²-9=0
X²=9 so x=+3 and -3
Or 5x-7=0
5x=7 so x=1.4 (or 7/5)

Please choose the option that would best fit the empty space above: Group of answer choices only one optimal solution multiple optimal solutions no solution, since it is infeasible no best solution, since it is unbounded None of the above
Answer:
Follows are the solution to this question:
Step-by-step explanation:
In this question, some of the data is missing, that's why this question can be defined as follows:
It Includes an objective feature coefficient, its sensitivity ratio is the ratio for values on which the current ideal approach will remain optimal.
When there is Just one perfect solution(optimal solution) then the equation is:
[tex]Max \ Z = \$ 5x_1 + \$10x_2\\\\Subject\ to: \\\\8x_1 + 5x_2 \leq 80\\\\2x_1 + 1x_2 \leq 100\\\\x1, x2 \geq 0[/tex]
When there are Several perfect solutions then the equation is:
[tex]Max \ Z = \$ \ 200x_1 + \$ \ 100x_2\\\\ Subject \ to:\\\\8x_1 + 5x_2 \leq 80\\\\2x_1 + 1x_2 \leq 100\\\\x1, x2 \geq 0[/tex]
When there is also no solution, since it is unlikely then the equation is:
[tex]Max \ Z = \$40x_1 + \$10x_2 \\\\Subject \ to:\\\\8x_1 + 5x_2 \leq 80\\\\2x_1 + 1x_2 \geq 100\\\\x_1, x_2 \geq 0[/tex]
When there is no best solution since it is unbounded then the equation is:
[tex]Max \ Z = \$ 30x_1 + \$15x_2 \\\\Subject to:\\\\8x_1 + 5x_2 \geq 80\\\\2x_1 + 1x_2 \geq 100\\\\x_1, x_2 \geq 0\\[/tex]

Question 5(Multiple Choice Worth 4 points)
The legs of a right triangle are 4 units and 7 units. What is the length of the hypotenuse?
Answer:
the answer is 33
Step-by-step explanation:
write the equation of the line parallel to the line below and passes through (-1,0)
parallel to the line with the points (0,3) and (1,0)
Answer:
y = -3x - 3
Step-by-step explanation:
Going from the point (0,3) to the point (1,0), we see that the rise (change in y) is -3 and the run (change in x) is 1. Thus, the slope of the new line is
m = rise/run = -3/1 = -3.
Using the coordinates of the given point (-1, 0), we'll find the equation of this line in point-slope form:
y - 0 = m(x + 1), or y = -3(x + 1), or (in slope-intercept form) y = -3x - 3
