In an arithmetic sequence, the difference between one term and the next is constant.

The 65th term of the arithmetic sequence is -734

Given the following arithmetic sequence:

-30, -41, -52 The standard formula for the nth term of an arithmetic sequence is given as

a(n) = a + (n - 1)d

Where a = first term

            n = number of term

             d = common difference

Let find the common difference

Common difference = second term - first termCommon difference

= -41 - (-30)

Common difference =  -41 + 30

Common difference = -11

Common difference = -52 - (-41)

Common difference = -52 + 41

Common difference = -11

Hence, the common difference

= -11

let:

a = -30n

= 65d = -11a(65)

= -30 + (65 - 1) * -11a(65)

= -30 + (64)*-11a(65)

= -30 + (-704)a(65)

= -30 - 704a(65)

= -734

Hence, the 65th term of the arithmetic sequence is -734

Step-by-step explanation:

20pounds/day * 14days * 20horses

The correct expression to determine the total hay consumption by 20 horses in two weeks is 20 × (20 × 14), which equals 5,600 pounds. Thus, the correct answer to the student's question is option (B).

The question from the student involves finding the total amount of hay consumed by a group of twenty horses over a period of two weeks. This problem can be solved with a straightforward multiplication.

Since one horse eats 20 pounds of hay each day, we can calculate the total hay consumption for one horse over two weeks (which is 14 days) by multiplying the daily consumption by 14:

To find out how much hay 20 horses eat in two weeks, we multiply the amount that one horse would eat in two weeks by 20:

Hence, the correct expression and evaluation to determine the total amount of hay consumed by 20 horses in two weeks is:

Answer:

The final sale price is $30,000.

Step-by-step explanation:

50% of $20,000 is $10,000.

$20,000+$10,000=$30,000.

Final answer:

To find the final sale price with a 50% markup on the original $20,000 price, add $10,000 (which is 50% of $20,000) to get a final sale price of $30,000.

Explanation:

To calculate the final sale price of a car after a 50% markup, we take the original purchase price of the car and add half of that price to it. If the car dealership buys a car for $20,000, a 50% markup would be half of $20,000, which is $10,000. So, the final sale price would be:

$20,000 (original price) + $10,000 (50% of $20,000) = $30,000.

Hence, the car dealership would sell the car for $30,000 after a 50% markup.

In the given case we can conclude that Using the laws of exponents, we can simplify i³ as 1

The laws of exponents, also known as the rules of exponents, are a set of fundamental mathematical principles that govern the manipulation and simplification of expressions involving exponents. These rules are essential for working with exponential functions and equations. Here are the basic laws of exponents.

Using the laws of exponents, we can simplify i³ as follows:

i³ = i * i * i

Since we know that i² = -1, we can substitute -1 for i² in the expression:

i³ = -1 * i * i

Next, we can use the associative property of multiplication to rearrange the expression:

i³ = -1 * (i * i)

Finally, we recognize that (i * i) is equal to i² = -1, so the expression simplifies to:

i³ = -1 * -1

Therefore, i³ = 1.

Answer:

B) 24/26

Step-by-step explanation:

The ratio of sine is opposite/hypotenuse.  This means the side opposite angle D, EF, has length 24 and the hypotenuse, DE, has length 26.

The ratio of cosine is adjacent/hypotenuse.  For cos E, we want the side adjacent to E (EF) and the hypotenuse (DE).  Using these, we have the ratio 24/26.

In DEF, sin D= 24/26  , then cos E = 24/ 26. Option B) 24/26 is correct.

Trigonometric ratios are defined as the sides and angles of a right-angled triangle are deal with in Trigonometry.

We have,

In DEF sin D= 24/26

Using Pythagoras Theorem,

[tex]P^2 + B^2 = H^2\\\\EF^2 +FD^2 = EF^2\\\\24^2 + FD^2 = 26^2\\\\FD^2 = 676 - 576\\\\FD^2 = 100\\\\FD = 10[/tex]

But, cos E = EF / ED

cos E = 24/ 26

Hence, we can say that In DEF, sin D= 24/26  , then cos E = 24/ 26.

Answer:

y = 1/4x-1

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b

m is the slope and b is the y intercept

but we do not know the slope y know the x intercept

(4,0 )

and  the y intercept

( 0,-1)

We can calculate the slope  using these points

m = (y2-y1)/ (x2-x1)

   = (-1-0)/(0-4)

    = -1/-4

    = 1/4

Now we can put the slope = 1/4 and the y intercept =-1 into the formula

y = 1/4x-1

Since y=7 when x=2, we can from here simplify and see that y=3.5 when x=1. If y=21, then we multiply 7 by 3 which is 21, and since we must keep a proportion, we must multiply 2 by 3 and get 6 as the answer.

Answer:

The y-intercept in coordinate form is (0, 4.5) and represents the taxi pick-up fee.  The equation is y=1.5x + 4.5.

Step-by-step explanation:

This question is asking for the slope and y-intercept of a linear equation.  A linear equation makes a straight line based on a constant rate of change.  For this problem, the cost per mile is the slope, while the independent variable 'x' is the number of miles and the dependent variable 'y' is the total cost.  In order to first find slope, you need to use the two points given (7, 15) and (10, 19.5) to set up a change in y / change in x, or (19.5-15)/(10-7) or 4.5/3 which is 1.5.  So the slope, or cost per mile is $1.50.  To find the y-intercept (b), or the cost of the pick-up fee, simply fill in your equation y=1.5x + b with your other variables and solve for 'b'.  So, 15 = (1.5 x7) + b.  or 15 = 10.5 +b, subtract 10.5 from both sides of the equation to get b=4.5.

The distance between the two variable in the number line is = 10

A number line is a horizontal line that includes both negative and positive numbers with equally spread increments. The middle of the line is usually zero which marks the starting point of other numbers.

The distance between two numbers in a number line is the sum of their absolute value;

[-4] + [6] = 4 +6 = 10

Answer: 70 units

One way to find this answer is to get a very large number line (perhaps from -100 to 100; counting by 1s) and count out the number of spaces from -57 to 13. This method is impractical because it would take a long time.

A shorter method is to subtract the values and make the result positive. So we could say -57 - 13 = -70 which has an absolute value of 70. Or we can say 13 - (-57) = 13 + 57 = 70. Either way, the distance between the values on the number line is 70 units.

Step-by-step explanation:

does 2 by 7 = 11 by 37

11/2 = 5.5

7 x 5.5 = 38.5

No, these two figures are not scaled versions of each other.  11 is 5.5 times larger than 2 which means to be a scaled version we would multiply 7 by 5.5.  

7 x 5.5 = 38.5

In order to be a scaled version the second recangle would need to be 11 by 38.5

The second rectangle is a scaled version of the first rectangle with a scale factor of 1/5.5.

Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions of the actual figure or object.

To determine if two figures are scaled versions of each other, we need to compare their corresponding side lengths.

The ratio of the corresponding side lengths is the same for both figures, then they have scaled versions of each other.

As per the question, the first rectangle has sides with lengths 2 and 7 units, while the second rectangle has sides with lengths 11 and 37 units.

So, the ratio of the corresponding side lengths is 2/11 = 7/37.

The scale factor is the ratio of the corresponding side lengths.

In this case, the scale factor is 2/11 = 1/5.5.

Therefore, the second rectangle is a scaled version of the first rectangle with a scale factor of 1/5.5.
