The below calculation allows us to determine the amount of fruit juice and punch needed to create a fruit punch that is entirely fruit juice.

To create a fruit punch that is entirely fruit juice, we must calculate the ratio of fruit juice to total punch. To do this, we will use the following formula:

Fruit Juice Ratio = (Fruit Juice / (Fruit Juice + Punch)) x 100

For example, if we have 10 ounces of fruit juice and 10 ounces of fruit punch, the ratio of fruit juice to total punch is 50%. Therefore, we need to mix 50% fruit juice with 50% punch to create a fruit punch that is entirely fruit juice.

To calculate this for any given amount of fruit juice and punch, we simply plug the numbers into the formula. For instance, if we have 20 ounces of fruit juice and 60 ounces of punch, the ratio of fruit juice to total punch is 25%. Therefore, we need to mix 25% fruit juice with 75% punch to create a fruit punch that is entirely fruit juice.

By using this formula, we can easily determine the amount of fruit juice and punch needed to create a fruit punch that is entirely fruit juice.

We can use the formula Fruit Juice Ratio = (Fruit Juice / (Fruit Juice + Punch)) x 100 to calculate the ratio of fruit juice to total punch. This allows us to determine the amount of fruit juice and punch needed to create a fruit punch that is entirely fruit juice.

Answer:

A) . f(x) = –16x2 + 99x + 6  

AAAAAAA is the answerrrrrr!!!!

Step-by-step explanation:

By analyzing the data and the situation modeled, we got the vertex of the quadratic function, and with that, we conclude that the correct option is:

f(x) = –16x^2 + 99x + 6

Here we have the table:

x         y

0        5

1         90

2        140

3         160

4         150

First, we know that this represents the height of a ball that is thrown in the air, and we know that it must go up and then back, this means that the leading coefficient must be negative.

So there are two options:

f(x) = –16x^2 + 99x + 6

f(x) = –36x^2 + 37x + 5

Analyzing the data, we can see that the maximum value is at x = 3, so we can assume that the vertex is near x = 3.

Remember that for a quadratic:

y = a*x^2 + b*x + c

The x-value of the vertex is at:

x = -b/2a

Then for our functions the x-values of the vertex are:

f(x) = –16x^2 + 99x + 6

x = -99/(2*-16) = 3.1

f(x) = –36x^2 + 37x + 5

x = -37/(2*-36) = 0.5

The option that has a vertex near x = 3 is the first one, so that is the best fit.

f(x) = –16x^2 + 99x + 6

A model's scale ratio is the ratio of linear dimensions. The scale factor of the triangle is (1/2).

A model's scale ratio is the proportionate ratio of a linear dimension of the model to the equivalent characteristic of the original.

The scale ratio of the triangle can be found by taking the ratio of any one side of the dashed triangle to the solid triangle. Therefore, the scale ratio will be,

\(\rm Scale\ ratio = \dfrac{\text{Length of the dashed line}}{\text{Length of the solid line}}\\\\ Scale\ ratio = \dfrac{2}{4} = \dfrac{1}{2}\)

The blue line is the one that that slants from lower right to upper left. It has a negative slope as in - 1/2. The line is solid so that means the values of the line are included in the expression.

The area covered is purple, so y is less than the y values of the line. C is the only value that shows the paragraph above.

Answer:

a) 20 m/s²

b) 0

Step-by-step explanation:

average acceleration is, Vₙ - vₓ / Δt

where, Vₙ stands for final velocity,

Vₓ stands for initial velocity, and

Δt stands for change in time

according to the question,

for t₂, s = 2³ - 2² - 2 - 2 = 8 - 4 - 4 = 0

for t₄, s = 4³ - 4² - 4 - 2 = 64 - 16 - 8 = 64 - 24 = 40

substituting the values in the formulae,

average acceleration = 40 - 0 / 4 - 2 = 40/2 = 20 m/s²

when the velocity is 0 it indicates that acceleration will also be 0

A - The Average Acceleration Between:

T  =  2  and   T  =  4  is   16 m/s^2

B - The Acceleration When the Velocity is: Zero (0)   is  0 m/s^2  at  

      T = 1/3  and 4 m/s^2  at   T  = 1

        s(t)  =  t^3  - t^2  - t  -  2

        v(t) = d/dt(t^3  - t^2 - t - 2 )  = 3t^2  - 2t  -  1

        a(t) = d/dt(3t^2  - 2t  -  1 )  =  6t - 2

        a(2)  =  6(2) - 2 = 10

        a(4) = 6(4) - 2 = 22

        =  a(2) + a(4)/2  

        =   10 + 22/2

        =   16

        3t^2  -  2t  -  1   =  0

        t  =  1/3,  1

       a(1/3)  =  6(1/3)  -  2  =  0

       a(1)   =   6(1)     -  2   =  4

The year in which the approximate cost of a pizza was of $9 is given as follows:

2000.

The rule of 72 is a quick and simple mathematical formula that is used to estimate the number of years it takes for an investment or a debt to double, given a fixed annual interest rate. The rule states that if you divide 72 by the annual interest rate (expressed as a percentage), the result will give you an approximate number of years it takes for the investment or debt to double.

Hence the equation is given as follows:

Time to double = 72/Rate.

The rate for this problem is of 3.25%, hence the time to double is given as follows:

T = 72/3.25

T = 22 years.

Hence the pizza cost half of what it cost in 2022 in 22 years before, hence:

2022 - 22 = year of 2000.

If the subset of R^2 consisting of vectors of the form [a b], where a + b = 1 is a subspace. The statement: This set is closed under scalar multiplications This set is a subspace .This set is closed under vector addition The set contains the zero vector is False.

A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity.

Examples of vectors in nature are velocity, momentum, force, electromagnetic fields, and weight. A quantity or phenomenon that exhibits magnitude only, with no specific direction, is called a Scalar . Examples of scalars include speed, mass, electrical resistance, and hard-drive storage capacity.

Scalar multiplication is the multiplication of a vector by a scalar (where the product is a vector), and is to be distinguished from inner product of two vectors (where the product is a scalar).

For quaternion scalars and matrices:

λ = 2     A = \(\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right]\)

2A = 2\(\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right]\)

The actual length of the shortest side of the picnic area = (x * 0.5) / 12 feet.

We can start by converting the units in the drawing to the actual length by multiplying each unit by 0.5 inches.

If the shortest side of the picnic area is represented by x units on the drawing, then the actual length in inches can be found by x * 0.5 inches.

Next, we can convert the length in inches to feet by dividing by 12 inches/foot. So, the actual length in feet is given by: x * 0.5 inches / 12 inches/foot = x * 0.5 / 12 feet.

Therefore, the actual length of the shortest side of the picnic area in feet is given by x * 0.5 / 12 feet.

The use of a scale on a drawing is a common method for representing actual sizes of objects on a smaller or larger scale. The scale tells us how many units on the drawing correspond to a certain length in the real world. In this case, each unit on the drawing represents 0.5 inches in the real world.

To find the actual length of the shortest side of the picnic area, we start by determining how many units represent this length on the drawing. Let's call this length x units.

Next, we use the scale given to convert the units on the drawing to inches. This is done by multiplying each unit by 0.5 inches, since each unit on the drawing represents 0.5 inches in the real world. So, the length in inches is given by x * 0.5 inches.

However, the question asks for the length in feet, not inches. To convert inches to feet, we divide the length in inches by 12, since there are 12 inches in a foot. So, the actual length of the shortest side of the picnic area in feet is given by: x * 0.5 inches / 12 inches/foot = x * 0.5 / 12 feet.

The ordered pair (6,8) represents the number of calls made after the customer service center opened for 6 hours.

Given that the volume of calls, V( h), at a particular customer service center can be written as a function of the number of hours after opening each day, h. So, (6,8) means that the center has been opened for 6 hours and that there have been 8 calls during this period. It represents the value of the volume of calls V(6) which is 8. Therefore, after opening the customer service center for 6 hours, 8 calls were made.

This function has a direct relationship between the number of hours after opening the center and the number of calls made. Therefore, the longer the center is open, the more calls are expected to be received, and vice versa.

A triangle whose sides are all equal is called an equilateral triangle and its area is given by A=\(\frac{\sqrt{3} }{4}\) \(x^{2}\), where x is the side of the triangle.

The area of a rectangle is found by using the formula

A=lw, where l is the length and w is the width.

The given figure can be split into two shapes: a rectangle and an equilateral triangle as shown in the diagram. Let l be the length of the rectangle.

Add all of the sides of the window and equate their result to 16. Then solve for l.

x + x + l + x + l = 16

3x + 2l = 16

2l = 16 - 3x

l = \(\frac{16-3x}{2}\)

The total area of the window will be the sum of the area of the equilateral triangle ABE and the area of rectangle BCDE.

A = \(\frac{\sqrt{3} }{4}\)\(x^{2}\) + lx

Subsitute  \(\frac{16-3x}{2}\) for l into the obtained equation and simplify.

A =\(\frac{\sqrt{3} }{4}\)\(x^{2}\) + ( \(\frac{16-3x}{2}\))x

A = \(\frac{\sqrt{3} }{4} x^{2}\) + 8x - \(\frac{3}{2} x^{2}\)

Differentiate the obtained equation with respect to x and equate the first derivative to 0 to calculate the critical point x .

\(\frac{dA}{dx}\) = \(\frac{\sqrt{3} }{4}\) (2x) + 8 - \(\frac{3}{2}\) (2x)

0 = \(\frac{\sqrt{3} }{2}\) x - 3x + 8

x (3 - \(\frac{\sqrt{3} }{2}\)) = 8

x = \(\frac{16}{6-\sqrt{3} }\)≈3.74887

Again, differentiate the equation

\(\frac{dA}{dx}\) = \(\frac{\sqrt{3} }{2}\)x - 3x + 8  with respect to x.

\(\frac{d^{2}A }{dx^{2} }\) = \(\frac{\sqrt{3} }{2}\) - 3

The value of the second derivative is \(\frac{\sqrt{3} }{2}\)−3, which is negative. This implies that the area will be maximum at the critical point.

Subsitute x = 3.74887 into the equation

l = \(\frac{16-3x}{2}\) and simplify

l = \(\frac{16-(3)(.74887)}{2}\) ≈ 2.3767

The maximum light will enter through the window when the triangular portion will have the side length of 3.74887 feet and the dimensions of the rectangular portion will be 3.74887-ft-by-2.3767-ft.

The lack of calcium lines indicates that the star's outer atmosphere is not dense enough to produce observable absorption lines.

Calcium lines are dark absorption lines in the spectrum of a star or other astronomical object that are produced by the absorption of specific wavelengths of light by calcium atoms in the object's outer atmosphere.

If a star lacks calcium lines in its spectrum, it is likely to be a relatively young and hot star, with a surface temperature above about 7,000 K. This is because the calcium lines that are typically observed in the spectra of cooler stars are formed in the star's outer atmosphere, which is cooler and more diffuse than the layers closer to the star's core.

The absence of calcium lines in the spectrum of a star suggests that its outer atmosphere is relatively thin or transparent, and that the star's light is not passing through enough calcium-rich material to produce observable absorption lines.
