The graph that shows the given situation is attached, and the required solution is the inequality 4x + 2y ≥ 45.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

We have been given that the price for each bucket of popcorn was $4. The price of each drink was half the price of a bucket of popcorn.

The total amount of spend is $45

As per the given condition, the required inequality would be as

4x + 2y ≥ 45

The situation's representation is in the attached graph with labels for the intercepts.

Here y-axis represents the number of drinks, and the x-axis represents the number of buckets of popcorn.

Thus, the graph that shows the given situation is attached, and the required solution is the inequality 4x + 2y ≥ 45.

Step-by-step explanation:

⇒ equation: (p√−3)+q

Perimeter is the total distance around the edge of a two-dimensional shape. It is calculated by adding up the lengths of all sides of the shape.

Calculations:

Let the width of the swimming pool be represented by 'w'.

The perimeter of a rectangle is given by the formula:

Perimeter = 2(length + width)

In this case, we are given the perimeter and the length, so we can substitute those values into the formula and solve for the width:

70 = 2(24 + w)

Dividing both sides by 2, we get:

35 = 24 + w

Subtracting 24 from both sides, we get:

w = 11

Therefore, the width of the swimming pool is 11 yards.

So the equation that can be used to find the width is:

w = (Perimeter - 2×length)/2

or

w = (70 - 2×24)/2 = 11.

To answer this question we will use the following property of logarithms:

Dividing the given equation by 4 we get:

Simplifying the above result we get:

Applying the natural logarithm we get:

Applying the property of logarithms we get:

Therefore:

Answer: Option D.

The dimensions of the rectangle are 7 feet by 9 feet.

Let's use algebra to solve this problem.

Let x be the width of the rectangle in feet. Then, according to the problem, the length of the rectangle is 2 feet longer than the width, or x + 2 feet.

The area of a rectangle is given by the formula\(A = length x width.\) So, we can write:

A = (x + 2) x x

Simplifying this expression, we get:

A = x^2 + 2x

We know from the problem that the area of the rectangle is 63 square feet. So, we can substitute this value for A and solve for x:

63 = x^2 + 2x

Rewriting this equation in standard form:

x^2 + 2x - 63 = 0

Now, we can use the quadratic formula to solve for x:

x = (-2 ± sqrt(2^2 - 4(1)(-63))) / (2(1))

x = (-2 ± sqrt(4 + 252)) / 2

x = (-2 ± sqrt(256)) / 2

x = (-2 ± 16) / 2

x = -9 or x = 7

Since the width of the rectangle cannot be negative, we reject the solution x = -9. Therefore, the width of the rectangle is 7 feet.

The length of the rectangle is 2 feet longer than the width, or x + 2 = 7 + 2 = 9 feet.

So, the dimensions of the rectangle are 7 feet by 9 feet.

Answer:

Vertical Shrink of a factor of 1/4

Step-by-step explanation:

Since we are manipulating a in f(x) = a(bx - h)² + k, we are dealing with vertical stretch (x > 1) and vertical shrink (x < 1). Since 1/4 < 1, we have a vertical shrink of 1/4.

Answer:  if you multiply the f(x) by 1/4 the graph seems to narrow, which is interpreted as a positive vertical shift .  The y value (output)  is 4 times greater

If you multiply the x² by 1/4, the graph seems to widen, which is interpreted as a negative vertical shift.  The y value is less by a factor of 1/4

Step-by-step explanation:  I am reading the question literally: multiplying f(x) by 1/4.  (This may be dangerous as mathematicians have their own lingo, and some words have specialized meanings that English majors haven't learned!)

I understand that f(x) or any other function is the y-output. So in order to graph a function, it is legitimate to substitute "y" for f(x).

I am attaching a graph with the f(x)=x² in red       f(x) = (1/4)x²  in green  and  (1/4)f(x) = x²  in blue.

As you can see, very different results:  Substituting 2 for x  

in red original  4 = 2²  

in green f(x) = (1/4)(2²) .  1 = (1/4)(4)

in blue (1/4)f(x) = x²   (1/4) 16 = (2²) =.  This is probably not the intended result, but it is literally what happens if you multiply the left side!  16  is the output on the graph.

So, despite my efforts to make sense of this, I realize that this answer is mistaken, and I hope someone can clear up my confusion, please!

Grams of flour needed for every 200200200 and grams of sugar = 300300300 grams

The equation that represents how many grams of flour we need for some grams of sugar is fff = 222/333

Let’s assume fff as grams of flour and sss as grams of sugar.

So, the ratio for grams of flour:grams of sugar will be,

= fff:sss = 200200200:300300300

Hence, fff = 222/333 × sss

Ratio is a comparison between two things where it tells how much one thing contains the other thing.

The angular separation between violet light (410 nm) and red light (685 nm) passing through a diffraction grating with a spacing of d = 3.33x10^(-6) m can be calculated using the formula for angular separation in diffraction, given by θ = λ / d, where θ is the angular separation, λ is the wavelength, and d is the grating spacing.

For violet light with a wavelength of 410 nm (4.10x10^(-7) m), the angular separation for m = 2 is θ_violet = λ_violet / d = (4.10x10^(-7) m) / (3.33x10^(-6) m) = 0.123 radians.

For red light with a wavelength of 685 nm (6.85x10^(-7) m), the angular separation for m = 2 is θ_red = λ_red / d = (6.85x10^(-7) m) / (3.33x10^(-6) m) = 0.206 radians.

Therefore, the angular separation between violet and red light for m = 2 is 0.206 radians - 0.123 radians = 0.083 radians.

Using a calculator, the difference between the arithmetic average ROR and the weighted average ROR is Option B) 0.1%

arithmetic average ROR is given as

(2.1% + 4.4% - 7.8% + 10.5%) / 4 =  0.02300

The Weighted Average ROR

[(0.021 x 3200 ) + (0.044 x  1750) + (-0.078 x 1235) + (0.105 x   2300)] / (3200 + 1750 + 1235 + 2300) =  0.0341037124337065

Thus:

The Weighted Average ROR - arithmetic average ROR

= 0.0341037124337065 - 0.02300

= 0.01110371243 x 100

On April 15, there will be 50 + 28 + 36 = 114 flowers in the rose garden. So, the answer is 114 flowers as a whole number.

We are given the number of flowers budding in a rose garden on three different dates- April 3, April 6, and April 9. We can observe that there is a difference of 12 flowers between April 3 and April 6, and a difference of 20 flowers between April 6 and April 9. Thus, we can conclude that the number of flowers is increasing at a faster rate in the second three-day period. To find the number of flowers on April 15, we need to continue this pattern of increase. From April 9 to April 12, we can predict that there will be an increase of 30 flowers (as the rate of increase has been consistently higher in each three-day period). Therefore, on April 12, there will be a total of 80 flowers in the rose garden.

Continuing with the same pattern, we can predict that there will be an increase of 40 flowers from April 12 to April 15. Therefore, on April 15, there will be a total of 120 flowers in the rose garden.We can predict that there will be 120 flowers in the rose garden on April 15. From April 3 to April 6 (three days), the number of flowers increased from 18 to 30, which is an increase of 12 flowers. From April 6 to April 9 (another three days), the number increased from 30 to 50, an increase of 20 flowers.

The denominator of Bayes' Theorem uses the Total Probability Rule.

Therefore the answer is total probability rule.

The Total Probability Rule states that for any events A and B, P(B) = P(B|A)P(A) + P(B|A')P(A'). In other words, the probability of event B happening is equal to the probability of event B happening given that event A has occurred, multiplied by the probability of event A occurring, plus the probability of event B happening given that event A has not occurred, multiplied by the probability of event A not occurring.

The denominator of Bayes' Theorem uses the Total Probability Rule to ensure that the probabilities of all the possible events sum up to 1, which is a requirement of any valid probability distribution. The denominator in Bayes' Theorem represents the normalizing constant that makes the probabilities of the different hypotheses sum to 1. The Total Probability Rule is used to calculate this normalizing constant by summing the probabilities of the hypotheses given the data over all possible values of the data.
