What is the minimum value for the function shown in the graph?

Answer:

The zeroes of the function are: [tex]\frac{-1}{3}[/tex].

Option b would be the correct answer.

Step-by-step explanation:

The zeros of a function are defined as the point at which the value of the function is zero. We can say the zeros are the x values where the graph intersects the x-axis. We obtain these algebraically by setting the function equal to zero then solving.

Given

[tex]y=3x+1[/tex]

Lets find all real zeros of the function.

Replace [tex]y[/tex] with 0.

[tex]0=3x+1[/tex]

Subtract 1 from both sides of the equation

[tex]-1=3x[/tex]

Divide both sides of the equation by 3.

[tex]\frac{-1}{3} =\frac{3x}{3}[/tex]

Simplify the right side by cancelling the common factor of 3.

[tex]\frac{-1}{3} =x[/tex]

Half a kilogram of mixed nuts costs 36 cents.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

Five-sixths of a kilogram costs 60 cents.

That means,

1 kilogram of mixed nuts costs = 60 x 6/5 = 72 cents.

So,

half a kilogram of mixed nuts costs = 72/2 = 36 cents.

Therefore, the required cost is 36 cents.

The amount of fence needed to enclose a rectangular garden is 90 feet.

To determine the amount of fence needed to enclose a rectangular garden with length 14 feet and width 31 feet, you need to calculate the perimeter of the rectangle. The perimeter is the total length of all four sides of the rectangle.

The formula for the perimeter of a rectangle is given by

2 * (length + width)

In this case, the length is 14 feet and the width is 31 feet, so the perimeter is

2 * (14 + 31) = 2 * 45 = 90 feet

This means that 90 feet of fence is needed to enclose the rectangular garden.

The amount borrowed with 4% interest was 1100, and the amount borrowed with 3.5% interest was 6000 - 1100 = 4900.

Let x be the amount of the loan with 4% interest and y be the amount of the loan with 3.5% interest. Then, x + y = 6000, because the total amount borrowed is 6000.

The interest owed on the 4% loan after 5 years is 4% of x per year, so the total interest owed after 5 years is 5 * 0.04x = 0.20x.

Similarly,

The interest owed on the 3.5% loan after 5 years is 3.5% of y per year, so the total interest owed after 5 years is 5 * 0.035y = 0.175y.

The total interest owed after 5 years is $1062.50, so 0.20x + 0.175y = 1062.50.

Now we have two equations, so we can solve for x and y.

First, substitute x + y = 6000 into the second equation, and we get,

0.20x + 0.175(6000 - x) = 1062.50

Expanding the second term, we get,

0.20x + 1035 - 0.175x = 1062.50

0.025x = 27.50

Dividing both sides by 0.025,

x = 1100

So the amount borrowed with 4% interest was 1100, and the amount borrowed with 3.5% interest was 6000 - 1100 = 4900.

The linear inequality will be 2.5x+1.5y<=9, where x=boxes of popcorn and y=no. of drinks.

What are linear inequalities?

Inequality represents the mathematical expression in which both sides are not equal. If the relationship makes the non-equal comparison between two expressions or two numbers, then it is known as inequality in Maths. In this case, the equal sign “=” in the expression is replaced by any of the inequality symbols such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤) or not equal to symbol (≠). The different types of inequalities in Maths are polynomial inequality, rational inequality, absolute value inequality.

The symbols ‘<‘ and ‘>’ express the strict inequalities and the symbols ‘≤’ and ‘≥’ denote slack inequalities. A linear inequality seems exactly like a linear equation but there is a change in the symbol that relates two expressions.

e.g. y>x+2

Now,

Given that  Shiloh and Mario went to the movies. At the theater a small box of popcorn costs $2.50 each and each drink costs $1.25 each.

Shiloh and Mario only have $9 to spend.

The x-coordinates of the inflection points of this function are −1 and −1/3.

In this case, we are looking for the open intervals on which the function f(x) = −x⁴ − 9x³ + 4x − 6 is concave up (down) and the x-coordinates of the inflection points of the function.

To find the open intervals on which f is concave up, we must first calculate the second derivative of the function.

The second derivative of the function f(x) is

=> f''(x) = −12x³ − 27x² + 4.

This means that the function f is concave up when f''(x) > 0 and concave down when f''(x) < 0. Solving the equation f''(x) > 0 will give us the intervals on which the function is concave up.

These are the intervals (−∞, −1), (−1, −1/3), and (−1/3, ∞).

Similarly, solving the equation f''(x) < 0 will give us the intervals on which the function is concave down. These intervals are (−1, −1/3) and (−1/3, 0).

We can now determine the x-coordinates of all inflection points of the function f by finding the x-values at which the second derivative is equal to zero.

Solving the equation f''(x) = 0 will give us the x-coordinates of the inflection points, in this case −1 and −1/3.

Answer:

1 and 1/6

Step-by-step explanation:

You have to add together the growth of the 2 weeks. So, 1/3 + 5/6 but to add these you need to find the common denominator. I would change 1/3 to have a denominator of 6. To turn 3 into 6 you have to multiply by 2 and whatever you do to the bottom you do to the top so 1 x 2. Now that your fraction of 1/3 is 2/6, you can add the 2 weeks together. 2/6 + 5/6 = 7/6, which can also be written as 1 and 1/6.
