Step-by-step explanation:

1. 4 cubed is 64 (4 x 4 = 16 x 4 = 64

2. Choice A. y=3x(x+5)+4 is a parabola

Answer:

To solve this problem, we can use Pythagorean theorem, it tells us that the square of the hypotenuse is equal to the sum of the square of the other two sides.

When we look at these side lengths, we can see that only the second answer is suitable because from the lengths, we can predict that 13 is the length of the hypotenuse, 5 is the length of the shorter leg and 12 is the length of the other leg, and when you actually calculate it, the result is correct as well:

5² + 12² = 25 + 144 = 169

13² = 169

So the answer is B

I’m thinking that the answer is B! Sorry if I’m wrong!:)

Answer:

The second term is -6 , the fourth term is 0 , the eleventh term is 21

Step-by-step explanation:

* Lets revise the explicit formula

- An explicit formula will create a sequence using n, the number

 position of each term.

- If you can find an explicit formula for a sequence, you will be able

 to quickly and easily find any term in the sequence by replacing

 n with the number of the term you want

- It defines the sequence as a formula in terms of n.

* Now lets solve the problem

- The formula of the sequence is A(n) = -9 + (n - 1)(3)

- A(n) is any term in the sequence

- n is the position of the number

- To find the second term put n = 2

∵ n = 2

∴ A(2) = -9 + (2 - 1)(3) = -9 + (1)(3) = -9 + 3 = -6

* The second term is -6

- To find the fourth term put n = 4

∵ n = 4

∴ A(4) = -9 + (4 - 1)(3) = -9 + (3)(3) = -9 + 9 = 0

* The fourth term is 0

- To find the eleventh term put n = 11

∵ n = 11

∴ A(11) = -9 + (11 - 1)(3) = -9 + (10)(3) = -9 + 30 = 21

* The eleventh term is 21

Answer:

Second term = -6

Fourth term = 0

Eleventh term = 21

Step-by-step explanation:

We are given the following explicit formula of an arithmetic sequence and we are to find the second, fourth and the eleventh terms of this sequence:

[tex]a_n=-9+(n-1)(3)[/tex]

where [tex]a_n[/tex] = nth term, [tex]a_1=-9[/tex] and [tex]n[/tex] = number of term.

Second term [tex](a_2) = -9+(2-1)(3)[/tex] = -6

Fourth term [tex](a_4) = -9+(4-1)(3)[/tex] = 0

Eleventh term [tex](a_{11}) = -9+(11-1)(3)[/tex] = 21

Answer:

The minimum value of this function is -40.

Step-by-step explanation:

Recall that the minimum of a quadratic whose graph is a parabola that opens up, as this one does, is the vertex of the graph.  The x-coordinate of the vertex is given by x = -b / (2a), where a is the coefficient of the x^2 term and b is that of the x term.

Here, x = -12 / (2*2), or x = -12/4, or x = -3.

Find the y-value at this x-value:  f(-3) = 2(-3)^2 + 12(-3) - 22, or

                                                      f(-3) = 2(9) - 36 - 22, or -40.

The vertex is at (-3, -40).  The minimum value of this function is -40.

The provided quadratic function y=2x²+12x-22 has no local minimum or maximum, as indicated by the application of the second derivative test, which results in a point of inflection rather than an extrema.

The minimum or maximum of the quadratic function y=2x²+12x-22. To locate the extrema of a quadratic function, we often use the first derivative test. However, the information provided indicates the derivative vanishes at x = 2 (y' = 0), but the second derivative test (y" = 6x - 12) reveals that this point is a point of inflection rather than a minimum or maximum. The second derivative being zero at x = 2 implies that there is no concavity change and hence, no local extrema. Therefore, for this particular quadratic function, there is no local minimum or maximum. The function can be rewritten as y = (x - 2)³ + 8, which shifts the function y = x³ two units to the right and eight units upwards, further emphasizing that it indeed has no local extrema.

Final answer:

To calculate the gain percentage, subtract the gain from the selling price to get the cost price, and then divide the gain by the cost price and multiply by 100. The dealer's gain percentage is approximately 6.25%.

Explanation:

The subject of the question is to calculate the gain percentage of a dealer who sells an article for ₹1636.25 and gains ₹96.25. To find the gain percentage, we need to identify the cost price first. The cost price (CP) can be calculated by subtracting the gain from the selling price (SP), which gives us CP = SP - Gain = ₹1636.25 - ₹96.25 = ₹1540.

Next, we calculate the gain percentage using the formula:

Gain Percentage = (Gain / Cost Price) * 100

Substituting the values, we get:

Gain Percentage = (₹96.25 / ₹1540) * 100

Therefore, the gain percentage of the dealer is approximately 6.25%.

Answer:

Step-by-step explanation:

The zeros of this cubing function are easily read from the graph:  {-20, -5, 15}.

The factors of this polynomial are therefore (x + 20), (x + 5) and (x - 15).

The y-intercept is (0, 1).

The function is thus f(x) = a(x + 20)(x + 5)(x - 15).

According to the y-intercept, if x = 0, y = 1.

Thus, y = 1 = f(0) = a(20)(5)(-15), or 1 = a(100)(-15), or 1 = -1500a.

Then a = -1/1500, and the function is:

f(x) = (-1/1500)(x^3 + .. +  .. + ... ).  We must multiply out (x + 20)(x + 5)(x - 15) to obtain f(x) in finished form.

Answer:

zeros: (-20, 0), (-5, 0) and (15, 0)

factors: (x + 20), (x + 5) and (x - 15)

f(x) = a*(x + 20)*(x + 5)*(x - 15)

a = -1/1500

f(x) = -1/1500*(x + 20)*(x + 5)*(x - 15)

f(x) = -1/1500*x^3 - 1/100*x^2 + 11/60x + 1

Step-by-step explanation:

The zeros of the function are those points where the function intercepts the x-axis. They are: (-20, 0), (-5, 0) and (15, 0)

The zeros of a polynomial are expressed as factors as follows: (x - a) where a is a zero. Then, for this case, the factors are (x + 20), (x + 5) and (x - 15)

The equation of f(x) use the factors and the leading coefficient as follows: f(x) = a*(x + 20)*(x + 5)*(x - 15)

Applying the distributive property of multiplication, we get the expanded form:

f(x) = a*(x + 20)*(x + 5)*(x - 15)

(x + 20)*(x + 5) = x^2 + 5x + 20x + 20*5 = x^2 + 25x  + 100

f(x) = a*(x^2 + 25x  + 100)*(x - 15)

(x^2 + 25x  + 100)*(x - 15) = x^3 - 15x^2 + 25x^2 - 15*25x + 100x - 100*15 = x^3  + 15x^2 - 275x - 1500

f(x) = a*(x^3 + 15x^2 - 275x - 1500)

The y-intercept of the graph is (0, 1). Replacing this point into the function equation:

1 = a*(0 + 20)*(0 + 5)*(0 - 15)

1 = a*20*5*(-15)

1 = a*(-1500)

a = -1/1500

Replacing this value  into the function equation:

f(x) = (-1/1500)*(x^3 + 15x^2 - 275x - 1500)

f(x) = -1/1500*x^3 - 1/100*x^2 + 11/60x + 1

A 1:3

Step-by-step explanation:

Point P(-1, -12/5) partitions the line segment AB in the ratio of 2:1, which is calculated using the section formula in coordinate geometry.

To determine the ratio at which point P partitions AB, we can use the concept of section formula in coordinate geometry. The section formula states that if a point P(x, y) divides the line segment AB in the ratio m:n, then its coordinates are given by:

[tex]\[ x = \frac{mx_2 + nx_1}{m + n} \quad \text{and} \quad y = \frac{my_2 + ny_1}{m + n} \][/tex]

Substituting the given coordinates of A(-3, -4), B(2, 0), and P(-1, -12/5), we can form two equations with the unknowns m and n. Solving for m and n will give us the required ratio.

[tex]\[ -1 = \frac{m \cdot 2 + n \cdot (-3)}{m + n} \text{ and } (-\frac{12}{5}) = \frac{m \cdot 0 + n \cdot (-4)}{m + n} \][/tex]

Solving the equations, we find m = 2 and n = 1, meaning P divides AB in the ratio of 2:1, which is option B.

A and B are independent events if:

 C.   The probability of buying bread and cheese is : 0.12

Two events  A and B are said to be independent.

                     if P(A∩B)=P(A)×P(B)

where P denote the probability of an event.

Here,

Event A= A shopper buys bread

and Event B=A shopper buys cheese

Also we have:

P(A)= 0.60 and P(B)= 0.20

If A and B are independent events then,

P(A∩B)=0.60×0.20

i.e.

P(A∩B)=0.12

i.e.If A and B are independent then the probability of buying bread and cheese is: 0.12

Also we know that:

P(A∪B)=P(A)+P(B)-P(A∩B)

If A and B are independent then,

P(A∪B)=0.60+0.20-0.12

i.e.

P(A∪B)=0.68

If A and B are independent then the probability of buying bread or cheese is: 0.68

Answer:

Break even occurs at 2800 juice boxes.

Step-by-step explanation:

Fixed cost form the factor = $1400

Variable cost per unit juice box = 15 cents = $0.15

Let number of juice boxed produced to get brek even point = x

Then total cost = c(x)= 1400+0.15x

Selling price per unit juice box = 65 cents = $0.65

Then total sales = R(x)= 0.65x

At break even both sales and cost will be equal so we get:

[tex]0.65x=1400+0.15x[/tex]

[tex]0.65x-0.15x=1400[/tex]

[tex]0.50x=1400[/tex]

[tex]x=\frac{1400}{0.50}[/tex]

[tex]x=2800[/tex]

Hence break even occurs at 2800 juice boxes.
