The quadratic function f whose zeros are -4 and -1 is f(x) = x² + 5x + 4.

Roots are the points where the graph intercepts with the x-axis, at that point y or f(x) = 0.

Given the roots in the question;

-4 and -1.

x = -4 was found by solving for x when x - (-4) = y or f(x) and we know that y or f(x) = 0

Hence, the factor is

x - (-4) ⇒ ( x + 4 )

x = -1 was found by solving for x when x - (-1) = y or f(x) and we know that y or f(x) = 0

Hence, the factor is

x - (-1) ⇒ ( x + 1 )

Next, we combine the factors and expand;

f(x) = ( x + 4 )( x + 1 )

f(x) =  x( x + 1 ) +4( x + 1 )

f(x) = x² + x + 4x + 4

Combine like terms

f(x) = x² + 5x + 4

Therefore, the quadratic function f whose zeros are -4 and -1 is f(x) = x² + 5x + 4.

Answer:

b. {1, 2, 3, 4, 5}

Step-by-step explanation:

Given function:  

c = 25n + 6

(where c is the total purchase cost and n is the number of coins)

Domain:  input values → n-values

If there is a limit of 5 coins per purchase, this means that you can purchase up to and including 5 coins at any one time.  

Therefore, the domain is:  {1, 2, 3, 4, 5}

{1, 2, 3, 4, 5} is a reasonable domain for this function.

So, the correct answer is:

b. {1, 2, 3, 4, 5}.

The cost function for purchasing n coins is given by c = 25n + 6.

However, there is a limit of 5 coins per purchase.

This means that the number of coins (n) should not exceed 5,

as it is not possible to purchase more than 5 coins in a single purchase.

Therefore, a reasonable domain for this function would be the set of numbers from 1 to 5,

since n can take any value between 1 and 5, inclusive.

Hence, {1, 2, 3, 4, 5} is a reasonable domain for this function.

So, the correct answer is:

b. {1, 2, 3, 4, 5}.

Answer:

9.5

Step-by-step explanation:

When rounding to the nearest tenth, check to see what the hundredths place value is.

If it is 0.05 or greater, we will round the tenths place up one.

If not, the tenths place will remain the same.

Since 9.52 has a hundredths place value of 0.02, we will keep the same tenths place value.

So, the correct answer is 9.5

We will see that the equation has only one solution, so the correct option is B.

For an equation of the form:

p(x) = C

Where p(x) is an expression that depends on x, and C is a constant.

The solutions are all the values of x that make the equality true.

For our case, we have:

x = -5

Notice that there is only one value of x that makes the equality true, if we replace x by -5 we get:

-5 = -5

So that is the only solution for the equation, then we conclude that the equation has only one solution, and the correct option is B.

The function f(x) = 2x² - 7x + 10 is an odd function.

f(-x) = 2(-x)² - 7(-x) + 10

      = 2x² + 7x + 10

-f(x) = -[2x²- 7x + 10]

      = -2x² + 7x - 10

To determine whether the function f(x) = 2x² - 7x + 10 is even, odd, or neither, we compare f(-x) and -f(x).

1. f(-x) = 2x² + 7x + 10

2. -f(x) = -2x² + 7x - 10

To determine if f(-x) = -f(x) (even function), we substitute -x for x in f(x) and check if the equation holds.

1. f(-x) = 2x² + 7x + 10

         = f(x) (not equal to -f(x))

Since f(-x) is not equal to -f(x), the function is not even.

Next, to determine if f(-x) = -f(x) (odd function), we substitute -x for x in f(x) and check if the equation holds.

2. -f(x) = -2x² + 7x - 10

        = -(2x² - 7x + 10)

        = -(f(x))

Since -f(x) is equal to -(f(x)), the function is odd.

The number of routes that Paula can take using graph theory is; E: 4

We will observe that out of the 12 cities, 6 of them possess 3 edges going in/out of them.

The 6 cities are such that there are 2 at the top, 2 at the bottom, and 1 on each side.

In graph theory terms, we can say that they are of degree 3.

Thus, at least 1 edge connecting to each of these cities cannot therefore be used. Furthermore, the same concept applies to the start and end points, due to the fact that we don't want to return to them.

There are 6 + 2 = 8 vertices that we can tell have 1 unused edge, and then we have 17 - 13 = 4 unused edges to work with due to the fact that we have 17 edges in total, and as such must use exactly 13 of them).

Finally, we notice that at each of the 2 cities marked with an O on a path in the image attached, that there are 2 possibilities such that it's either we continue straight and cross back over that same path later, or we will make a left turn, and then turn rightward when we approach the junction again.

If you can buy 1 bunch of seedless green grapes for $2, then $18 we can buy 9 bunches.

The concept used here is a simple division to find out how many bunches of seedless green grapes can be purchased with a given amount of money.

In this case, we know the cost of one bunch of seedless green-grapes ($2) and we are given a total amount of money ($18) that we can spend on grapes. We can use division to find out how many bunches we can buy with that amount.

⇒ Number of bunches = ($18)/($2) per bunch,

⇒ Number of bunches = 9 bunches;

Therefore, with $18, you can buy 9 bunches of seedless green grapes.

In order to explain why -4 - 2 equals -8, let's start with the equation 0.2 = 0. By analyzing this equation, we can uncover the reason behind this seemingly counterintuitive result.

1. Begin with the equation 0.2 = 0.

2. Subtract 0.2 from both sides of the equation to isolate the variable: 0.2 - 0.2 = 0 - 0.2.

  This simplifies to 0 = -0.2.

3. Observe that the right side of the equation, -0.2, is a negative number.

4. Recall that subtracting a negative number is equivalent to adding its positive counterpart. Therefore, -0.2 is the same as +0.2.

5. Rewrite the equation as 0 = +0.2.

6. Notice that 0 on the left side of the equation is equal to 0 + 0, since any number added to zero remains unchanged.

7. Substitute 0 + 0 for 0 in the equation: 0 + 0 = +0.2.

8. Simplify the equation to 0 = +0.2.

9. Finally, recognize that a positive number cannot equal zero. Hence, the equation 0 = +0.2 is false.

10. As a result, the original equation 0.2 = 0 is invalid.

11. Therefore, the logical consequence is that any subsequent deductions based on this invalid equation would also be incorrect.

12. Consequently, -4 - 2 does not equal -8, as per the explanation derived from the flawed equation.

To summarize, by analyzing the equation 0.2 = 0, we can determine that subsequent deductions based on this equation are incorrect. Hence, -4 - 2 does not equal -8.

A_n = A_n-1 + 2 represents the recursive formula.

A recursive formula is a formula or equation that describes a sequence or function in terms of itself. In other words, the formula for a given term or value depends on the formula for one or more previous terms or values.

For example, the Fibonacci sequence is a sequence of numbers in which each term is the sum of the two preceding terms: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, ...

This sequence can be described recursively using the following formula:

F(n) = F(n-1) + F(n-2)

where F(n) is the nth term of the sequence, F(n-1) is the (n-1)th term, and F(n-2) is the (n-2)th term.

Another example of a recursive formula is the factorial function, which is defined for non-negative integers n as:

n! = n * (n-1)!

This formula states that the factorial of n is equal to n multiplied by the factorial of (n-1). This recursive definition can be used to compute the factorial of any non-negative integer.

Angle B = 102°

Angle A = 78°

Explanation

The first thing to note in answering this is that for parallelograms,

- Opposite angles are equal to each other.

- Adjacent angles (angles close to each other) sum up to give 180°.

So, in the given parallelogram, we can see that the two angles given are adjacent angles. Hence,

2x + 10° + 3x = 180°

5x + 10° = 180°

5x = 180° - 10°

5x = 170°

Divide both sides by 5

(5x/5) = (170°/5)

x = 34°

So, we can solve for Angle B now

Angle B = 3x = 3 (34°) = 102°

Angle A = 2x + 10° = 2(34°) + 10° = 68° + 10° = 78°
