What is the sum of the first and last value? Use / to represent division and to separate a numerator from denominator What is the summation equal to
The number of numbers in the sequence is k/2.
The sequence starts with k/2, then k/4, then k/6, and so on. Since k is an odd number, the sequence will stop when we reach 0. Therefore, the number of numbers in the sequence is k/2.
The number of pairs of real numbers in the sequence is k/4.
This is because for every number in the sequence, there is a corresponding number that is its negative. For example, if k = 1, then the sequence is 1/2, -1/2, 1/4, -1/4, and so on. There are k/4 numbers in the sequence, and half of them are positive and half of them are negative.
The sum of the first and last value in the sequence is k/2.
This is because the first value in the sequence is k/2, and the last value in the sequence is -k/2. Since k is an odd number, k/2 is not equal to -k/2. Therefore, the sum of the first and last value in the sequence is k/2.
The summation is equal to 0.
This is because the terms of the summation cancel each other out. For example, if k = 1, then the summation is 1/2 - 1/2 + 1/4 - 1/4 + ... = 0.

Which type of triangle can be constructed with a 50° angle between two 8-inch sides? A. Equilateral B. Isosceles C. Scalene D. Obtuse.
The correct option is (C) Isosceles. An Isosceles triangle can be constructed with a 50° angle between two 8-inch sides.
This is because isosceles triangle having two sides that are equal in length, and have 50° angle, which is acute angle, that is less than 90°. This state that the remaining angle in the triangle must also be acute triangle, as the sum of all angles in a triangle must equal 180°.
This means that the remaining angle must be 80° (i.e. 180 - 50 = 80). An isosceles triangle is triangle consisting of two sides of equal length and two angles of equal measure. The two equal sides that make up the isosceles triangle are referred to as the base and the remaining side is height or altitude.

(a) find a number such that if | x 2 2| , , then | 4x 2 8| , «, where « 5 0.1. (b) repeat part (a) with « 5 0.01.
Answer:
(a) To find a number such that | x 2 2| , , we need to solve the inequality | x 2 2| < «. First, let's solve | x 2 2| < 0.1:
x 2 2 < 0.1
x 2 < 2.1
x < √2.1
Now, let's solve | x 2 2| > -0.1:
x 2 2 > -0.1
x 2 > 1.9
x > √1.9
So, the solution to | x 2 2| < 0.1 is √1.9 < x < √2.1. Any number in this range will satisfy the inequality.
(b) To repeat part (a) with « 5 0.01, we need to solve the inequality | x 2 2| < 0.01. First, let's solve | x 2 2| < 0.01:
x 2 2 < 0.01
x 2 < 2.01
x < √2.01
Now, let's solve | x 2 2| > -0.01:
x 2 2 > -0.01
x 2 > 1.99
x > √1.99
So, the solution to | x 2 2| < 0.01 is √1.99 < x < √2.01. Any number in this range will satisfy the inequality.

joe needs to transfer 28 quarts of oil into one gallon containers joe calculated that he needs 112 container's but he made a mistake in his calculations identify and correct his error
Answer:
The answer to your question is given below.
Step-by-step explanation:
To know the mistake that Joe made and the possible correction, we shall convert 28 quart to gallon.
This is illustrated below:
Recall:
4 quart = 1 gallon
Therefore,
28 quart = 28 quart × 1 gallon / 4 quart
28 quart = 7 gallon
Therefore, 28 quarts is equivalent to 7 gallons.
Hence, Joe made a mistake in his calculations by multiplying 28 quarts by 4 instead of dividing 28 quart by 4.
How many 9-digit palindromes are there with all the digits being even and each digit appearing no more than twice?
Answer: 96
Step-by-step explanation:
A palindrome is a number that is the same when reading in both ways (right to left, and left to right), for example, 121
Then, we have 9 digits, and all the digits need to be even.
the options are: 0, 2, 4, 6, 8.
Now, we can tink a 9 digit number as 9 empty slots, and in each slot, we can put a number.
But because this is a palindrome, the first digit must be equal to the ninth, and the second digit must be equal to the eight, and so on.
So we can tink it as actually only 5 slots, where in each slot, we can put an even number, now let's count the options that we have in each selection.
For the first digit we have 4 options: 2, 4, 6 and 8 (0 is not counted here because if the first digit was a 0, then this would not be a 9 digit number).
for the second digit, we have also 4 options (because we already toked one, but now the 0 can be chosen)
for the third digit, we have 3 options
for the fourth digit, we have 2 options
for the fifth digit, we have only one option.
The total number of combinations is equal to the product of the number of options for each selection:
C = 4*4*3*2*1 = 96

The number of protons to neutrons in the nucleus of an atom is 5 to 6.If the numbers of protons in the nucleus is 30 then find the number of neutrons
Answer:
36 neutrons
Step-by-step explanation:
The ratio of the protons to neutrons is 5:6, or 5 protons/6 neutrons. You know there are 30 protons, so this means you can set up proportions. Keeping the protons on the top, 5 protons/6 neutrons = 30 protons/x neutrons. You can cross-multiply from here, but how I find it helpful to think of it is seeing that you have to multiply 5 protons by 6 to get to 30 protons, so you'd have to also multiply the 6 neutrons by 6 to get x neutrons. Doing so (6x6) will get you 36. Don't forget your units! (:

The value of f(g(x)) is x^2 + 1/x
How to determine the valueA function is an expression that describes the relationship between an independent variable and dependent variable.
Given the functions;
f(x) =
\( \sqrt[3]{x} \)
g(x) =
\( \frac{ x+ 1}{ {x}^{3} } \)
How to determine the function
Substitute the value do x as the value of the function g(x)
f(g(x)) =
\( \sqrt[3]{ \frac{x + 1}{ {x}^{3} } } \)
Find the cube root of the expression
f(g(x)) =
\( \frac{ {x}^{3} + {1}^{3} }{x} \)
Find the cube of the values
f(g(x)) =
\( \frac{ {x}^{3} + 1 }{x} \)
Divide through by x, we have;
f(g(x)) = x^2 + 1/x
Thus, the value of f(g(x)) is x^2 + 1/x

Alex and Jill share £100 in the ratio of 1 : 7 work out how much money Alex gets?
Answer:
$87.50
Step-by-step explanation:
If they split the money 1:7 this means they divided it into 8 portions. (Because 7+1=8). So do $100/8=12.5.
(You never specified who got 1 portion and who got 7, so I will assume Alex got the 7)
Let's say Jill got the 1 portion, she gets $12.50.
Let's say Alex got the 7 portion, he got $12.50 x 7 = $87.50
The amount Alex got is £12.5.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
Alex and Jill share £100 in a ratio of 1:7.
Total ratio = 8x
So,
Alex = 1x
Amount = 1x/8x x 100 = £12.5
Jill = 7x
Amount = 7x/8x x 100 = £87.5
Thus,
Alex got £12.5.

Letf(x, y) = 2ex − y.Find the equation for the tangent plane to the graph of f at the point
The final equation for the tangent plane to the graph of f at the point (a, b) is z = 2e^a(x - a) - y + 2e^a - 2b. This equation represents the plane that is tangent to the graph of f at the specified point (a, b).
To find the equation for the tangent plane to the graph of the function f(x, y) = 2e^x - y at a given point (x0, y0), we need to calculate the partial derivatives of f with respect to x and y at that point.
The partial derivative of f with respect to x, denoted as ∂f/∂x or fₓ, represents the rate of change of f with respect to x while keeping y constant. Similarly, the partial derivative of f with respect to y, denoted as ∂f/∂y or fᵧ, represents the rate of change of f with respect to y while keeping x constant.
Let's calculate these partial derivatives:
fₓ = d/dx(2e^x - y) = 2e^x
fᵧ = d/dy(2e^x - y) = -1
Now, we have the partial derivatives evaluated at the point (x0, y0). Let's assume our point of interest is (a, b), where a = x0 and b = y0.
At the point (a, b), the equation for the tangent plane is given by:
z - f(a, b) = fₓ(a, b)(x - a) + fᵧ(a, b)(y - b)
Substituting fₓ(a, b) = 2e^a and fᵧ(a, b) = -1, we have:
z - f(a, b) = 2e^a(x - a) - (y - b)
Now, let's substitute f(a, b) = 2e^a - b:
z - (2e^a - b) = 2e^a(x - a) - (y - b)
Rearranging and simplifying:
z = 2e^a(x - a) - (y - b) + 2e^a - b
The final equation for the tangent plane to the graph of f at the point (a, b) is z = 2e^a(x - a) - y + 2e^a - 2b.
This equation represents the plane that is tangent to the graph of f at the specified point (a, b).
