If 24 ounce can of Fanta cost $1.75 then it cost 13.71 per ounce.

A division is a process of splitting a specific amount into equal parts.

Given that a 24 ounce can of Fanta cost $1.75.

We need to find the how many does it cost per ounce.

To find this we need to divide twenty four by one point seven five.

Cost per ounce is twenty four by one point seven five

Cost = 24/1.75

Cost per ounce=13.71

So a 24 ounce can of Fanta cost $1.75 can cost 13.71 per ounce.

Hence, if 24 ounce can of Fanta cost $1.75 then it cost 13.71 per ounce.

Answer:  y = -2

========================================

Explanation:

Find the slope of line m using the slope formula

slopeM = (y2-y1)/(x2-x1)

slopeM = (2-8)/(-1-6)

slopeM = -6/(-7)

slopeM = 6/7

The slope of line m is 6/7. The perpendicular slope is -7/6. We flip the fraction (aka reciprocal) and flip the sign (from positive to negative). The phrase "flip the fraction and flip the sign" is a handy way to think of "negative reciprocal", at least in my opinion. Note how the two slopes 6/7 and -7/6 multiply to -1 to prove they are perpendicular slopes

We'll use the slope formula again to set up the slope for line n. We don't know y, but we can set the fraction equal to -7/6 and solve for it.

slopeN = (y2-y1)/(x2-x1)

slopeN = (y-5)/(5-(-1))

slopeN = (y-5)/(6)

-7/6 = (y-5)/6

-7*6 = 6(y-5)

-42 = 6y-30

6y-30 = -42

6y = -42+30

6y = -12

y = -2

So in short, if y = -2, then line n goes through (-1,5) and (5,y) = (5,-2). The slope of line N is computed to be...

slopeN = (y2-y1)/(x2-x1)

slopeN = (-2-5)/(5-(-1))

slopeN = (-2-5)/(5+1)

slopeN = -7/6

which is the proper slope value we want.

Answer:

A'(3, - 1)

Step-by-step explanation:

Under a reflection in the y-axis

a point (x, y) → (- x, y), hence

A (- 3, - 1) → A'(3, - 1)

The coordinate A(-3,-1) on reflection across y-axis transforms to (3,-1)

A Cartesian coordinate system in a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates.

Given here: The coordinate of a Triangle A as (-3,-1)

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Thus The vertex of the triangle (-3,-1) it changes to (3,-1)

The algebraic representation for the transformation is given by '

(x,y)⇒(-1×x,1×y)

     ⇒(-x, y)

Hence, The coordinate A(-3,-1) on reflection across y-axis transforms to (3,-1)

Step-by-step explanation:

To find the sum, convert the fractions to have the same denominator. Add the whole numbers and the fractions separately. The sum of 12 1/4 and 5 5/6 reduced to lowest terms is 17 13/12.

To find the sum of 12 1/4 and 5 5/6, we need to convert the fractions to have the same denominator. The common denominator for 4 and 6 is 12. So, we can rewrite 12 1/4 as 12 3/12 and 5 5/6 as 5 10/12. Now we can add the whole numbers, 12 and 5, which gives us 17. Then, we add the fractions, 3/12 and 10/12, which equals 13/12. Therefore, the sum of 12 1/4 and 5 5/6 reduced to lowest terms is 17 13/12.

Answer:

[tex]1000 {e}^{.06 \times 5} = 1349.86[/tex]

The correct answer is B.

After 5 years with continuous compounding at 6%, $1,000 will grow to approximately $1,349.86.

To find the future value of an account with continuous compounding, we use the formula:

A = Pe^(rt)

where:

In your case:

P = $1,000, r = 6% (or 0.06 in decimal form), and t = 5 years.

So plug these values into the formula:

A = $1,000 * e^(0.06*5)

After you calculate this, you'll find that the value of A is approximately $1,349.86. Therefore, after 5 years, your balance would be $1,349.86 so the answer is (b).

Odd exponents ensure at least one real root for polynomials, while even exponents may result in no real roots. Multiplying even functions together, or odd functions together, results in an even function. These properties have applications in areas like quantum mechanics.

Odd and even exponents greatly influence the behavior of polynomial functions. For polynomials with odd exponents, they will always have at least one real root. This is because polynomials of odd degree tend to positive infinity as x goes to positive infinity and negative infinity as x goes to negative infinity, therefore they must cross the x-axis at some point. A polynomial like x³ - x + 17 exemplifies this behavior.

On the other hand, polynomials with even exponents may not have any real roots, as they never need to cross the x-axis; for example, x² + 1 is always positive for any real value of x and thus has no real roots.

Even functions and odd functions also display characteristic properties when multiplied. An even function times an even function yields an even function (e.g., x² e⁻²), and an odd function times another odd function results in an even function (e.g., x sin x).

In contrast, an odd function times an even function gives an odd function. These properties are particularly useful in fields such as quantum mechanics where symmetry plays an important role in solving equations like Schrödinger's equation.

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

9 > 2

i.e. 9 is to the right of 2 on a horizontal number line

As we know that in the Cartesian plane, upper most is for y- positive coordinate, lower most is for y- negative coordinate

Similarly, right most is for x-positive coordinate and left most is for x- negative coordinate.

And we have 9>2

Both 2 and 9 are positive numbers so, both numbers must be in the right part of axis.

And 9 is always right of 2 on a horizontal number line.

Hence, Option 'C' is correct.

Final answer:

To find the height of the water in each container, we must calculate the volumes of the rectangular prism and the cylinder, set equations based on their volumes that add up to 80 cm³, and solve for the heights of the water in each container.

Explanation:

To solve this, the volume of the containers and then the height of the water in each container must be determined.

The volume of the rectangular prism can be found with the formula:
Volume = length × width × height. So, the volume = 4cm × 2cm × height of water for the rectangular prism.

The volume of the cylinder is calculated using the formula: V = πr²h, where 'r' is the radius and 'h' is the height of water for the cylinder. Given the radius is 1 cm, the formula simplifies to V = π × 1 cm × height of water.

Knowing the combined volume of the water is 80 cm³, we set up the equations considering the volume of water held by each container and solve for the heights of water in both the rectangular prism and the cylinder. The calculations will provide the individual heights of water, ensuring they add up to the total volume of 80 cm³.

The slope-intercept form:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (-1, -10) and (1, 0). Substitute:

[tex]m=\dfrac{0-(-10)}{1-(-1)}=\dfrac{10}{1+1}=\dfrac{10}{2}=5[/tex]

Put the coordinates of the point (1, 0) to the equation of line:

[tex]0=5(1)+b[/tex]

[tex]0=5+b[/tex]      subtract 5 from both sides

[tex]-5=b\to b=-5[/tex]

For the line's equation, calculate the slope from the provided points to get 5, and use one point to find the y-intercept, which is -5. The line's equation is y = 5x - 5.

To find the equation of a line in slope-intercept form, which is y = mx + b.

We need to determine the slope (m) and the y-intercept (b).

Given two points on the line, (-1, -10) and (1, 0), we can calculate the slope using the formula

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}\\ m = \frac{0-(-10)}{1-(-1)}\\ m = 5[/tex]

Next, we use one of the points to find the y-intercept, b. If we use the point (1, 0), we can substitute the slope and the coordinates into the slope-intercept equation:

0 = (5)(1) + b, which simplifies to b = -5.

Thus, the equation of the line is y = 5x - 5.

Divide 46 on both sides to get f(x)=((x+2)^3-3)/46. The domain ranges from negative infinity to infinity. The range ranges from -infinity to infinity as well because the exponent is 3, so the resulting number may be negative.

The solution set is { x | x[tex]\leq[/tex] -2 or x[tex]\geq[/tex] 1}

Step-by-step explanation:

The given inequality is

[tex]x^{2} +x-2>0[/tex]

Let us factor [tex]x^{2} +x-2[/tex]

so we have

[tex](x+2)(x-1)>0[/tex]

Let us find zeros of [tex](x+2)(x-1)[/tex]

[tex](x+2)(x-1)=0[/tex]

[tex]x+2=0[/tex]   or  [tex]x-1 =0[/tex]

[tex]x= -2[/tex] or [tex]x=1[/tex]

so we have intervals (-∞ , -2) , (-2 , 1) and (1, ∞)

we need to find in which interval is [tex]x^{2} +x-2[/tex] is greater than 0

so we will assume the value of x in each interval and will plug it in [tex]x^{2} +x-2[/tex] and will check if we get negative or positive value

Let us check the sign of [tex]x^{2} +x-2[/tex] in (-∞ , -2)

we can take x=-3 and plug it in [tex]x^{2} +x-2[/tex]

so we have

[tex](-3)^{2} +(-3)-2= 9-3-2= 4[/tex]   ( which is greater than 0)

This shows  (-∞, -2) is one of the solution set

similarly we can check the sign of [tex]x^{2} +x-2[/tex] in (-2,1)

we take x= 0 , so we have

[tex]0^{2} +0-2=-2[/tex]  ( which is less than 0)

This shows  (-2,1) is not the solution set

now we check the sign of [tex]x^{2} +x-2[/tex] in (1 ,∞)

we can assume x= 2, so we have

[tex]2^{2} +2-2 = 4[/tex]  ( which is greater than 0)

This shows  (1 ,∞) is the solution set

Hence the solution set in interval notation  (∞ ,-2)∪(1,∞)

we can write this as { x | x[tex]\leq[/tex] -2 or x[tex]\geq[/tex] 1}
