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) ).

How do you find the cloud base altitude?

To find the cloud base altitude, you can use the dew point temperature and the air temperature. The formula is: Cloud Base (feet) = (Temperature - Dew Point) × 400. Measure the air temperature and the dew point temperature, then plug the values into the formula. Alternatively, you can use a hygrometer or weather balloon data for more precise measurement.

How are slope and the dependent variable similar?

Slope and the dependent variable are similar in that they both play crucial roles in understanding relationships in linear equations. The slope indicates the rate of change of the dependent variable with respect to the independent variable, reflecting how much the dependent variable increases or decreases as the independent variable changes. Both concepts are integral to analyzing trends in data, helping to describe and predict outcomes in a given context.

What is the genesis of monomial binomial and polynomial?

The terms monomial, binomial, and polynomial stem from Greek roots. "Mono-" means one, "bi-" means two, and "poly-" means many. A monomial is an algebraic expression with a single term, a binomial consists of two terms, and a polynomial is a sum of multiple terms. These classifications help in understanding and simplifying algebraic expressions.

What number is larger 0.174 or 0.5?

To compare any decimals follow :=

#1 ; bring both decimals to the same number of decimal places, by inserting suffix zeroes.

Hence 0.174 & 0.5 becomes 0.174 & 0.500 ( 3 d.p.).

#2 ; Drop the decimal point Hence 0174 & 0500

#3 ; Drop the prefix zeroes. Hence 174 & 500

#4 ; I think you will agree that 500 > 174

Hence it follows that 0.5 > 0.174

NB This method is good for comparing any decimals.

How do you get diameter from circumference?

What is the circumference of 12.45cm diameter?

Remember the circle equation.

C = pi d

In words, 'Circumference equals the constant 'pi' multiplied to a diameter'.

For circles of ANY size, pi = 3.141592.... ~ 3.14

NB Pi is an irrational number and the decimal recur to infinity. However, it is approximated to 3.14 for learning/school purposes.

Hence for a diameter of 12.45 cm

C = 3.14 X 12.45cm

C = 39.093 cm

Which way does a parabola open when the coefficient of its x2 term is a negative?

A parabola opens downward when the coefficient of its (x^2) term is negative. This means that the vertex of the parabola represents a maximum point. In contrast, if the coefficient were positive, the parabola would open upward, indicating a minimum point at the vertex.

How do you draw a rectangle with a perimeter of 12 units and an area equalling 8?

P = 12 = 2( l + w)

A = 8 = l*w.

Hence

6 = l + w

8 = l X w

It follows

w = 6 - l

Substitute

8 = l X ( 6 - l

Myltiply out

8 = 6l - l^(2)

l^(2) - 6l + 8 = 0

It is now in Quadratic form ; Factor

(l -4)( l -2) = 0

Hence ;(length) = 4

Widt = 2 .

How do you solve multiplicative inverse in algebra 2?

To solve for the multiplicative inverse of a number in Algebra 2, you simply take the reciprocal of that number. For a non-zero number ( a ), its multiplicative inverse is ( \frac{1}{a} ), since multiplying ( a ) by its inverse yields 1 (i.e., ( a \times \frac{1}{a} = 1 )). This concept is crucial when solving equations that involve fractions or when factoring expressions. Always remember that the multiplicative inverse is not defined for zero.
