In 1864, Sherman succeeded Grant as the Union commander in the Western Theater. He led the capture of the strategic city of Atlanta, a military success that contributed to the re-election of President Abraham Lincoln.

Step-by-step explanation:

The value   [tex]\displaystyle \sum^{2007}_{n = 2} F(n)[/tex] is 2016532.

The collection of positive and negative integers is known as an integer. Integers, like whole numbers, do not include the fractional portion. Integers can therefore be defined as numbers that can be positive, negative, or zero but not as fractions. On integers, we can carry out all arithmetic operations, including addition, subtraction, multiplication, and division. Integer examples include 1, 2, 5, 8, -9, -12, etc. "Z" stands for an integer. The Latin term "Integer," which implies entire or intact, is where the word "integer" first appeared. Zero, positive numbers, and negative numbers make up the particular set of numbers known as integers.

Integer examples include: -1, -12, 6, and 15.

Zero is not an integer that can be positive or negative. There is no (+ or -) sign on zero, making it a neutral number.

F(2) = 3

We learn that for the majority of the graphs by examining different graphs.

F(n) = n+1

3+4+5+5+7+8+9+9+··········+2008

= (1+2+3+4+5+·····+2008)-3-501

= [tex]\frac{(2008) \times( 2009)}{2} -504[/tex]

Answer:

5s + 3.50d < 40

Step-by-step explanation:

if you were to total up the costs of a snack and drink together you'll end up with $8.50

-multiply $8.50 until you reach $40 mark

i.e 8.50×2(means 2 of each item) = $17

8.50×3 = $25.5

8.50×4 = $34

8.50×5= $42.5

-if you look at it, the calculation for 5, the pricing is now over the budget therefore the answer is then 5s + 3.50d < 40 because she can only spend up to $34 at most

Answer:

Assume one diagonal of 2x and other of x inches. and sides of length =L inches.

Area of rhombus = 2*2x*x/2=2x^2 = 81 x=9/sqrt.2 and 2x=9*sqrt 2.

Diagonals are x=6.365 inch 2x=12.73 inch check area =12.73*6.365= 81.026 sq.inch.

Step-by-step explanation:

According to the standard deviation rule, 99.7% of people have an IQ between 55 and 145.

The standard deviation rule which is the empirical rule in statistics tells us that for distributions that have the normal shape, approximately 99.7% of the observations will fall within 3 standard deviations of the mean.

Now, In this question the mean is 100, and the standard deviation is 15. Thus, we can say that approximately 99.7% of the observations (IQ scores) fall between 100 − (3 * 15) and 100 + (3 * 15) or between 55 and 145.

Now, approximately 100% − 99.7% = 0.3% of the observations fall outside this interval. Since the normal shape is symmetric, approximately 0.15% of the observations fall above 145.

The approximation of the trigonometry ratio cot(5) is 11.43

The trigonometry ratio expression is given as

cot(5)

In trigonometry ratio, we have the following equation

cot(x) = 1/tan(x)

This means that x = 5

Substitute 15 for x in the equation cot(x) = 1/tan(x)

So, we have

cot(5) = 1/tan(5)

Using a calculator, we have:

cot(5) = 1/0.0875

Evaluate the quotient

So, we have

cot(5) = 11.4286

Approximate the above result

So, we have

cot(5) = 11.43

Hence, the approximation of the trigonometry ratio cot(5) is 11.43

If Gabriel continues the pattern of running that he has done on the past four weeks, the miles he will run on the 7th week is 2 miles.

Gabriel's pattern of running is such that he increases the number of miles by 0.25 miles every week.

This is why he ran 0.5 miles, and then 0.75 miles and then 1 mile.

If he keeps going like this, one the 7th week, he will run:

The Simplification of the expression 6(3x-17) + 2x -18 = 9(4x+7) -9 + 17 and value for the unknown x, is approximately 11.94

6(3x-17) + 2x -18 = 9(4x+7) -9 + 17

18x - 102 + 2x - 18 = 36x + 63 - 9 + 17

18x + 2x - 36x = 63 - 9 + 17 + 102 + 18

- 16x = 191

x = 191 / - 16

x = 11.9375

Approximately,

x = 11.94

The difference between a tax rebate and a discount is For a rebate the tax, the tax is calculated on the full price, and the customer receives the rebate later. For a discount, the tax is calculated on the reduced price after the discount is applied.

A tax rebate is also known as a tax refund and the purpose of it is to pay back a tax payer when they paid more taxes than they were meant to pay. It is therefore calculated on the full amount of tax.

This is different from a tax discount which works by using the discount to reduce the amount of tax owed and then you can pay off the discounted amount as tax.

On solving linear equation 1.05x=12.60, we get that Emma has 48 quarters.

Let x be any variable then ax + b = c  b is an linear equation in one variable.

where a, b, c are constants  then we get solution for x as

x=(b-c)/a

Given as Emma has 4 times as many as quarters as nickels

Let the no of nickels be x

Then as there are 4 times as many as quarters as nickels

then no quarters be = 4x

Value of one nickel = 5 cents= $0.05

Value of one quarter = 25 cents = $0.25

Therefore x nickels and 4x quarters worth is = x(.05)+4x(.25)

Total worth of given nickels and quarters = $12.60

Then 0.05x+x = 12.60

This is an linear equation in one variable

1.05x=12.60

x= 12.60/1.05

x=12

A programme declares a variable whenever it states that it requires one. Place declaration statements for our brief programmes in-between the main method's two curly braces. The variable's name and data type are provided in the declaration. It could also provide a specific value that has to be entered into the variable.

When a variable is given a value for the first time, it is said to be initialized. The symbol = stands in for the assignment operator. Instead of writing int I and then 9, you can establish a variable for addition and then give it a value in the same line by writing int I = 9.

the point equidistant from the points (0, 0, 0), (0, 4, 0), (3, 0, 0), and (2, 2, -3) are (1/2, 1, 3/2).

Equidistant is a synonym for "equally distant," which is the state of two points being at the same distance from one another. Equidistant implies at the same distance from a location. The term "equidistant" is commonly used in reference to circles, perpendicular bisectors, parallel lines, and other geometrical concepts .Equidistant refers to the relationship between two or more objects or points that are situated at the same distance from one another. A point is considered to be equidistant from two other points when they are both located at the same distance from it. In the middle of the two starting points is a midway. The distance formula or the halfway formula can be used to demonstrate this.

Equation of sphere passes through origin is given by
