What is meant by factor?

In mathematics, a factor is a number or expression that divides another number or expression evenly without a remainder. Factoring is the process of finding the factors of a number or expression. In algebra, factoring is used to simplify expressions, solve equations, and find zeros of functions. By factoring, we can rewrite a complex expression or equation as a product of simpler expressions or factors.

To factor out [tex]$-\frac{1}{2}$[/tex] from the equation [tex]$-\frac{1}{2}(x-0)^2+x+4=0$[/tex], we can divide both sides of the equation by [tex]-\frac{1}{2}$:[/tex]

[tex]$-\frac{1}{2}(x-0)^2 \div -\frac{1}{2} + x \div -\frac{1}{2} + 4 \div -\frac{1}{2} = 0 \div -\frac{1}{2}$$[/tex]

Answer:

134.16 meters and length of shadow is 268.33 meters

Step-by-step explanation:

Applying Pythagoras. Let the the distance from the end of the shadow to building top be the hypotenuse side 300 meter, building height be X and the adjacent be the shadow length which is twice the height of the building 2XTherefore from Pythagoras theorem:Squared of hypotenuse side= to sum of squares of the other sidesC^2= a^2+b^2300*2= X^2+2X^290000= 5X^2X^2= 90000/5X^2=18000X= 134.16 meters2X = 268.33 metersTherefore the height of building is 134.16 meters and length of shadow is 268.33 meters

The solution for the equation x^2 - 10x = -100 is

The solution for the equation x^2 + 7x - 16 = 0 is

To complete the square for the equation x^2 - 10x = -100, we need to add and subtract  (b/2a)^2 = (10/2)^2 = 25 to both sides of the equation:

x^2 - 10x + 25 = -100 + 25

(x - 5)^2 = -75

x - 5 = ±√75i

x = 5 ± √(75)i

x = 5 ± 5√3 i

Therefore, the solutions are x = 5 + 5√3i and x = 5 - 5√3i.

For the equation x^2 + 7x - 16 = 0, we need to add and subtract (7/2)^2 = 49/4 to both sides of the equation:

x^2 + 7x + 49/4 - 49/4 - 16 = 0

(x + 7/2)^2 = 81/4

x + 7/2 = ±9/2

x = -7/2 ± 9/2

x = -8 or x = 1

Therefore, the solutions are x = -8 and x = 1.

We can simplify the square root of 98 by factoring 98 into its prime factors:

98 = 2 * 7 * 7

Now, we can take out one factor of 7 from the square root and simplify it:

Answer: 7.14 in²

Step-by-step explanation:

1) Find the area of the square: 2*2 = 4 square inches

2) We can see that there are 2 semi-circles with the same diameter or 2 inches. Use the area of a circle formula: A = r².

Since the diameter is 2 inches, the radius is diameter/2 which is 1 inch.

Plug this information into the formula.

A=

3) 4 + 3.14 = 7.14 inches²

The answer is the second option, 7.14 inches²

The majority of the marina's bolts are white. The remaining bolts are divided into 4/7 blue and the remainder red. There are 84 vessels at the marina if there are nine red boats.

Let's start by finding the fraction of bolts that are not red:

Fraction of white bolts: 3/4

Fraction of bolts that are not white: 1 - 3/4

Fraction of bolts that are not white = 4-3/4

Fraction of bolts that are not white = 1/4

Fraction of blue bolts: 4/7 of 1/4

Fraction of blue bolts = 4/28

Fraction of blue bolts = 1/7

Fraction of red bolts: 1/4 - 1/7

Fraction of red bolts = 7-4/28

Fraction of red bolts = 3/28

We know that there are nine red boats, which is equal to 3/28 of the total number of bolts. So we can set up an equation to solve for the total number of bolts:

3/28x = 9

Multiplying both sides by (28/3), we get:

x = (28/3) * 9

x = 28 * 3

x = 84

Therefore, there are 84 boats in the marina.

After answering the provided question, we can state that As a result, 145.62 square feet of glass are required to cover the entire pyramid.

A pyramid is a polygon formed by connecting points known as bases and polygonal vertices. For each hace and vertex, a triangle known as a face is formed. A cone with a polygonal shape. A pyramid with a floor and n pyramids has n+1 vertices, n+1 vertices, and 2n edges. Every pyramid is dual in nature. A pyramid contains three dimensions. A pyramid is made up of a flat tri face and a polygonal base that come together at a single point known as the vertex. A pyramid is formed by connecting the base and peak. The base's edges form triangle faces known as sides that connect to the top.

To determine how much glass is required to cover the entire pyramid, we must first determine the total surface area of the pyramid, including the base.

The formula for calculating the surface area of each triangular face is:

(1/2) x width x height

27.31 square feet = (1/2) x 7 feet x 7.79 feet

24 square feet = (1/2) x 6 feet x 8 feet

Simply multiply the length and width to find the area of the rectangular base:

7 feet by 6 feet equals 42 square feet

As a result, the total surface area of the pyramid is:

145.62 square feet = 2 (27.31 square feet) + 2 (24 square feet) + 42 square feet

As a result, 145.62 square feet of glass are required to cover the entire pyramid.

After answering the provided question, we can conclude that So the ratio of red apples to all the apples in the basket is 5:14.

In mathematics, ratios show how frequently one number is contained in another. For example, if there are 8 oranges and 6 lemons in a fruit dish, the ratio of oranges to lemons is 8 to 6. In a similar vein, the orange-to-whole-fruit ratio is 8, while the lemon-to-orange ratio is 6:8. A ratio is an ordered pair of numbers a and b expressed as a / b, where b is not zero. A ratio is an equation that equates two ratios. For example, if there is one boy and three girls (for every boy she has three girls), 3/4 are girls and 1/4 are boys.

(a) The ratio of green apples to all the apples in the basket is:

Green apples : Total apples = 9 : (9+5) = 9 : 14

So the ratio of green apples to all the apples in the basket is 9:14.

(b) The ratio of red apples to all apples in the basket is:

Red apples : Total apples = 5 : (9+5) = 5 : 14

The standard error of the mean for the given sample of 375 homes is 0.186. This means that the mean of 4.2, as estimated from the sample, is likely to be within 0.186 of the true population mean.

Standard deviation is a measure of the variability or spread of a dataset. It is calculated by taking the square root of the variance, which is the average of the squared differences from the mean. Standard deviation gives a measure of how spread out the values in a dataset are from the mean value. Higher standard deviation indicates greater spread or variability of the values.

The random variable X is the number of people in a household for a given sample size of 375 homes. This random variable is important in estimating the population mean of the number of people in a household.

To calculate the standard error of the mean (SE), we first need to calculate the sample size:

n = 375

Then, we can calculate the standard error of the mean as follows:

SE = (2.1)/(√375)

SE = 0.186

Therefore, the standard error of the mean for the given sample of 375 homes is 0.186. This means that the mean of 4.2, as estimated from the sample, is likely to be within 0.186 of the true population mean.
