Is 256 a prime or composite number?

Since 256 is an EVEN number, then it is a Composite number.

It is definitely NOT a prime number.

NB Remember ALL even numbers are composites, because they can all be divided by '2'. . This makes '2' a factor of all EVEN numbers.

Remember ALL even numbers end in 0,2,4,6,8. So any number that ends in one of these numbers is a composite , and NOT a prime number.

Except for '2' itself, all PRIME Numbers are ODD numbers. However, not all odd numbers are prime numbers., Numbers ending in '5' are odd numbers, but they are NOT prime number because they will all divide by '5' . All odd numbers end in 1,3,5,7,9. However, all prime numbers will only end in either 1,3,7, or 9.

Here are the prime number up to '20'.

2,3,5,7,11,13,17,19

What is 3c plus 4d-2e plus 2d plus 3e simplified?

To simplify the expression (3c + 4d - 2e + 2d + 3e), combine like terms. The terms with (d) are (4d + 2d = 6d), and the terms with (e) are (-2e + 3e = e). Thus, the simplified expression is (3c + 6d + e).

What is the function of a cloplasts?

Chloroplasts are organelles found in plant cells and some algae, responsible for photosynthesis. They contain the green pigment chlorophyll, which captures sunlight and converts it into chemical energy by transforming carbon dioxide and water into glucose and oxygen.

Additionally, chloroplasts play a role in synthesizing fatty acids and amino acids.

What is two algebraic expressions that have the same value are?

Two algebraic expressions that have the same value are called equivalent expressions. For example, (2(x + 3)) and (2x + 6) are equivalent because they simplify to the same value for any value of (x). This equivalence can be verified by substituting values for (x) or by simplifying the expressions.

How do you solve a order pair?

To solve an ordered pair, you typically need to determine the values of the two variables it represents, usually denoted as (x, y). This can involve substituting the values into an equation or system of equations to find a solution that satisfies both conditions. If you're dealing with a graph, the ordered pair can represent a point where the two axes intersect. Ensure that the values make sense in the context of the problem you are solving.

They also play a role in processes like autophagy, where damaged organelles are removed.

How many solutions are there to the equation below 4x - 9(x plus 1) 20 - 5x?

To solve the equation ( 4x - 9(x + 1) = 20 - 5x ), first simplify both sides. Expanding the left side gives ( 4x - 9x - 9 = 20 - 5x ), which simplifies to ( -5x - 9 = 20 - 5x ). Adding ( 5x ) to both sides results in ( -9 = 20 ), which is a contradiction. Thus, there are no solutions to the equation.

Which equation would generate an exponential decay curve?

An equation that generates an exponential decay curve is typically of the form ( y = ae^{-bx} ), where ( a ) is the initial value, ( b ) is a positive constant, and ( x ) represents time or another independent variable. In this equation, as ( x ) increases, the value of ( y ) decreases exponentially towards zero. Another common form is ( y = a(1 - r)^x ), where ( 0 < r < 1 ) also describes exponential decay.

The purpose of these equations is often to express one variable in terms of others, making them useful in various fields such as algebra and physics.

How can you test to determine whether a number is a factor of another number?

#1 For any EVEN number it will divide by '2'. So '2' is a factor.

e.g. 1,000,004

#2 For any number ending in '5' or '0' it will divide by '5'. So ;5; is a factor.

e.g. 505, or 1050

#3 For any number where the digits sum/add to '9' , then it will divide by '9'. So '9' is a factor. e.g. 153 ( 1 + 5 + 3 = 9)

#4 For any number where the inside digits sum to the total of the outside digits, then '11' is a factor . e.g. 132 (1 + 2 = 3)

#5 The only two numbers you MUST test mechanically are '3' & '7'.

What value of b makes the trinomal below a perfect square x2 bx 16?

To make the trinomial ( x^2 + bx + 16 ) a perfect square, we need it to be expressible in the form ( (x + p)^2 ), where ( p ) is a constant. Expanding ( (x + p)^2 ) gives us ( x^2 + 2px + p^2 ). To match the constant term, we set ( p^2 = 16 ), which gives ( p = 4 ) or ( p = -4 ). Thus, ( 2p = 8 ) or ( -8 ), meaning ( b ) must be ( 8 ) or ( -8 ).

What are the function of pawnshops?

Pawnshops serve as a financial service that allows individuals to secure short-term loans by using personal items as collateral. Customers can pawn valuables, such as jewelry or electronics, for immediate cash, with the option to reclaim their items by repaying the loan plus interest within a specified period. If the loan is not repaid, the pawnshop retains ownership of the item and can sell it to recover the funds. Additionally, some pawnshops sell pre-owned items, providing a marketplace for both buying and selling.

What is 5 squared plus b squared equals 13 squared?

The equation (5^2 + b^2 = 13^2) can be simplified to (25 + b^2 = 169). To find (b^2), subtract 25 from both sides, resulting in (b^2 = 144). Taking the square root gives (b = 12) or (b = -12). Thus, the values of (b) are 12 and -12.

Write the expression 2a plus b in the form of a fraction with a denominator of b?

To express (2a + b) as a fraction with a denominator of (b), you can rewrite it as follows:

[ \frac{2a}{b} + \frac{b}{b} = \frac{2a + b}{b} ]

Thus, the expression (2a + b) in the form of a fraction with a denominator of (b) is (\frac{2a + b}{b}).

How do you find the Y intercept given an equation?

To find the Y-intercept of an equation, set the value of ( x ) to 0 and solve for ( y ). In a linear equation of the form ( y = mx + b ), the Y-intercept is simply the value of ( b ). For other types of equations, substitute ( x = 0 ) and compute the resulting value of ( y ). This point, where the graph intersects the Y-axis, will have coordinates ( (0, y) ).
