Answer: (x +4)(x - 4)

Step-by-step explanation: Since x² - 16 represents the difference of two squares, it can be factored as the product of two binomials, one that has a plus in it and one that has a minus in it.

The first position in each binomial is filled by

the factors of x² that are the same, x times x.

The second position in each binomial is filled

by the factors of 16 that are the same, 4 times 4.

The answer therefore is (x + 4)(x - 4).

Answer:

The answer is -x^2-4x

Step-by-step explanation:

Answer:1/7

Step-by-step explanation: You take the amount that are springer spaniels and you put them with the whole of the dogs in the park 14 so you would have 2/14. You can reduce this fraction to 1/7 by dividing both the top and bottom of the fraction by 2.

The amount of interest earned on a deposit of $60.00 at a rate of 9% per annum for 2 years is $108.

As per the given problem:

Amount deposited = $60.00

Interest rate per year = 9%

The formula for calculating the interest is given by:

Interest = (Principal × Rate × Time)/100

Where Principal is the initial amount invested or deposited

Rate is the percentage of interest that you earn per annum

Time is the duration for which you want to calculate the interest

Putting the values in the above formula, we get:

Interest = (60 × 9 × 2)/100= (108 × 1)/1= $108

So, the amount of interest earned on a deposit of $60.00 at a rate of 9% per annum for 2 years is $108.

The end behavior is as x approaches negative infinity, f(x) approaches negative infinity as x approaches positive infinity, f(x) approaches negative infinity The only x-intercept of f(x) is x = 3.

The given function is f(x) = -x³ + 2x² + 3

1. End behavior:

As the leading coefficient of f(x) is negative, -x^3 dominates the behavior of the function as x approaches negative or positive infinity. Therefore, the end behavior of the function is:

2. X-intercepts:

To find the x-intercepts of f(x), we need to solve the equation f(x) = -x^3 + 2x^2 + 3 = 0. We can factor out a common factor of -1 to simplify the equation:

-x^3 + 2x^2 + 3 = 0

x^3 - 2x^2 - 3 = 0

Using synthetic division or long division, we can find that one of the roots of this equation is x = 3. We can then factor out (x - 3) using polynomial division to find the other two roots:

x^3 - 2x^2 - 3 = (x - 3)(x^2 + x + 1)

The quadratic factor x^2 + x + 1 has no real roots, so the only x-intercept of f(x) is x = 3.

3. Positive/negative:

To determine the sign of f(x) for different values of x, we can look at the sign of each factor in the polynomial:

Putting these together, we can make the following sign chart for f(x):

x                         f(x)

x < 0                   -

0 < x < 3                  +

x > 3                  -

4. Multiplicity:

The only root of f(x) is x = 3, which has multiplicity 1. This means that the graph of f(x) crosses the x-axis at x = 3 and changes sign at that point.

y+399=218

Step-by-step explanation:

total means added together meaning the outcome would be 218, and then just add y and 399 because they will be added for the total and boom you have an expression.

x ⊥ y, i.e., x and y are orthogonal.

To show that x ⊥ y, we need to show that x and y are orthogonal, i.e., their dot product is zero.

Let A be a matrix with distinct eigenvalues λ1 and λ2, and let x be an eigenvector of A corresponding to λ1. Then by definition, we have Ax = λ1x.

Now consider the transpose of A, denoted by AT. Let y be an eigenvector of AT corresponding to λ2, i.e., ATy = λ2y.

Taking the dot product of x and y, we have:

x · y = (xT) y  [where xT denotes the transpose of x]

Since A is a real matrix, we have:

(xT) y = xT (AT y) = xT (λ2y) = λ2 (xT y)

[where we have used the fact that AT y = λ2y and distributed the scalar λ2]

On the other hand, we have:

Ax · y = (λ1x) · y = λ1 (x · y)

[where we have used the fact that Ax = λ1x and distributed the scalar λ1]

Since x · y = (xT) y, we can combine the above two equations to get:

λ2 (xT y) = λ1 (x · y)

Since λ1 and λ2 are distinct, we have λ1 ≠ λ2. Therefore, we can divide both sides of the above equation by (λ1 - λ2) to get:

x · y = 0

Thus, we have shown that x ⊥ y, i.e., x and y are orthogonal.

Solving a linear equation we will see that after5 weeks you will have $105 on your piggy bank.

We know that it starts ar $45, and then you add $12 each week. Then the amount of money after W weeks is modeled by the linear equation:

y = 12*W + 45

You will have $105 when the value of y is 105, replacing that we get the equation below:

105 = 12W + 45

105 - 45 = 12W

60 = 12W

60/12 = W

5 = W

You will have $105 on your piggy bankafter 5 weeks.

(a) Simple interest

SI = P x R x T

Where:

R = simple interest in decimal form = 5/100= 0.05

SI = 18,000 x 0.05 x 10 = $9,000

Value of investment = 18,000 + 9,000 = $27,000

Step-by-step explanation:

For the first one use law of sine

\(\frac{x}{\sin(48)}=\frac{6}{\sin(50)}\\x=5.820640033\)

2.)

Solve for angle ABD

98

Next use law of cosine

x²=8²+5.820640033²-2*8*5.820640033*cos(98)

x=10.52810879

now just find the area

.5*8*5.820640033*sin(98)= 23.05597586

You can use the Pythagoras theorem for this since a right triangle is formed.

\(c^2 = a^2 + b^2\)

C = 12

A = 4

B = x

Input values:

\(12^2 = 4^2 + x^2\)

\(144 = 16 + x^2\)

\(128 = x^2\)

\(x = \sqrt{128}\)

\(x = 11.3137...\)
