$a^4 - 3a^2 + 9$ can be factorised as $(a^2 - 3)(a^2 + 3)$

To factor $a^4 - 3a^2 + 9$ as a product of two monic quadratics with integer coefficients, we can use the difference of squares factorization.

When an expression has the general form a²+2ab+b², then we can factor it as (a+b)². For example, x²+10x+25 can be factored as (x+5)². This method is based on the pattern (a+b)²=a²+2ab+b², which can be verified by expanding the parentheses in (a+b)(a+b).

$a^4 - 3a^2 + 9$ can be factored as $(a^2 - 3)(a^2 + 3)$

Notice that both factors are monic quadratics with integer coefficients.

So, $a^4 - 3a^2 + 9$ = $(a^2 - 3)(a^2 + 3)$

If 1500 g can be divided evenly into batches of bread that are 70 g each, then the baker should choose the 1500 g package.

To check this, we can divide 1500 g by 70 g to see how many batches of bread can be made:

1500 g / 70 g = 21.428571428571427

Since this is a non-whole number, it means that some of the dough would be wasted if the baker chooses a package of 1500 g. The baker should choose the 1500 g package, as it can be divided evenly into batches of bread that are 70 g each.

Answer:

x = 34 degrees

Step-by-step explanation:

angles TWU and PSR are vertical and equal

if TSU = 4x and QSR = x then PSQ = 3x

triangle PSQ has 180 degrees

we know the three interior angles of the triangle are:

x, x, 112

we found the 112 by subtracting 68 from 180 since PQR is a straight line which has 180 degrees

to find 'x' we do the following:

x + x + 112 = 180

2x + 112 = 180

2x = 68

x = 34

The value of x = -1 and y = 3.

To solve the system of equations using substitution, we can start by isolating one of the variables in one of the equations. For example, in the first equation, 7x - y = -10, you can add y to both sides to get y = 7x + 10.

Then we can substitute this expression for y into the second equation, 3y - x = 10, to get:

3(7x + 10) - x = 10

This simplifies to:

21x + 30 - x = 10

20x = -20

x = -1

Now we know that x = -1, we can substitute that back into the first equation or the expression we found for y to find the value of y

y = 7x + 10

y = 7(-1) + 10

y = -7 + 10

y = 3

So the solution of the system is x = -1 and y = 3

The y=5x-10 function is nonlinear.

A linear function is a function which forms a straight line in a graph. It is generally a polynomial function whose degree is utmost 1 or 0.  Although the linear functions are also represented in terms of calculus as well as linear algebra. The only difference is the function notation. Knowing an ordered pair written in function notation is necessary too. f(a) is called a function, where a is an independent variable in which the function is dependent. Linear Function Graph has a straight line whose expression or formula is given by; y = f(x) = px + q
Since you are using y, instead of f(x), I think it's more appropriate to call it a relationship. The equation y=5x-10 describes a set of points that fall on a line, but for it to be a linear function, it should be denoted as f(x)=5x-10.

The distinction isn't so interesting in this case, but how about the case x = y^2? This is a totally valid relationship, but it cannot be a function of x, since a function requires just one output for a given input.

No. If it was a linear function we should have y(λx)=λy(x), ∀x. But that's not what happens. Actually, this function is called an affine function. So, we can see that affine functions are obtained from the linear functions simply by performing a rigid movement.

The linear functions are those that have the form: y=ax.

Answer:$917.59

Step-by-step explanation:

The formula for compound interest is A = P(1 + r/n)^(nt) where A is the final amount, P is the principal (initial deposit), r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

In this case, the initial deposit is $500, the annual interest rate is 4%, the number of times compounded per year is 12 (monthly), and the number of years is 12.

So, we can plug in the values into the formula:

A = $500(1 + 0.04/12)^(12*12) = $500(1.003333333)^(144) = $500(1.835170816) = $917.585

The final amount in her account after 12 years is $917.58

To round to the nearest cent, we can use the following method:

If the digit in the thousandths place is less than 5, we keep the hundredths digit as is.

If the digit in the thousandths place is greater than 5, we round up the hundredths digit.

Answer:

  yes, for positive numbers

Step-by-step explanation:

You want to know if the number of arrays that represent a number is equal to the number of factor pairs of that number.

We assume that we're only concerned with Natural numbers (positive integers).

We assume that the factor pair 2×3 is indistinguishable from the factor pair 3×2, and that an array of 2 rows and 3 columns is indistinguishable from an array of 3 rows and 2 columns.

Each array corresponds to a factor pair. One factor of the pair specifies the number of rows; the other factor specifies the number of columns. The product of those factors is the number of interest.

Example

  12 = 1·12 = 2·6 = 3·4 . . . . . factor pairs listed with smallest factor first

The attachment shows arrays associated with these factor pairs.

If the number is a square number, then there will be an odd number of divisors. One of the divisors is repeated to make the factor pair. This results in a square array as one of the arrays that represent the square number. The second attachment shows arrays for the square number 9.

There will be as many arrays as there are factor pairs.

Jamie multiplied 3x and 7 by -5 to eliminate the parentheses.

This procedure is justified by the distributive property.

This property states that multiplying the total of two or more addends by a number will provide the same outcome as multiplying each addend by the number separately and then adding the results together.

When we need to multiply a number by the sum of two numbers, the distributive property of multiplication over addition comes into play. Let's multiply 7 by the sum of 20 plus 3 as an illustration. This can be expressed mathematically as 7(20 + 3).

The distributive rule of multiplication over addition and subtraction is another name for the distributive property. By its very name, the procedure implies that something will be divided or distributed. Both addition and subtraction are under the scope of the distributive law.

The number of real solutions to a quadratic equation depends on the coefficients of the quadratic equation.

A quadratic equation is an equation of the form ax2 + bx + c = 0, where a, b, and c are real numbers. This equation can have either 0, 1, or 2 real solutions. If a is equal to 0, then the equation is not a quadratic equation and can have any number of real solutions.

If the coefficient a is not equal to 0, then the number of real solutions depends on the value of the discriminant, b2 - 4ac. If the discriminant is positive, then there are two real solutions to the equation. If the discriminant is zero, then there is one real solution. If the discriminant is negative, then there are no real solutions.

In summary, a quadratic equation can have 0, 1, or 2 real solutions depending on the value of the discriminant.

The measurement of angles C and F are 63°  and 59° respectively

Trigonometry is the branch of mathematics that deals with the relationship between ratios of the sides of a right-angled triangle with its angles.

In the given image, you notice that angles A, B and C form a right-angled triangle. So the measurement of angle C is 90°. Also, the sum of angles in a triangle is 180°. Thus:

A + B + C = 180°

27° + 90° + C = 180°

117° + C = 180°

C =  180° - 117°

C = 63°

Likewise, angles D, E and F form a right-angled triangle. So the measurement of angle E is 90°. Also, the sum of angles in a triangle is 180°. Thus:

D + E + F = 180°

31° + 90° + F = 180°

121° + F = 180°

F =  180° - 121°
