The softball team is selling hats. John bought 3 for $24.00. Stacey bought 5 for $40.00. Jim bought 2 for $16.00.
Why does this verbal description represent a proportional relationship?

Answer:

Step-by-step explanation:

(i) Find the value of y when x = - 2

(ii) See the graph attached

(iii) The axis of symmetry is the vertical line passing through the vertex, which is x + 1 = 0 or x = - 1.

This is also reflected on the attached graph.

(iv) From the graph it is visible that in the given interval the function is decreasing, so the value at x = - 4 is the maximum and the value at x = - 2 is minimum:

These two points too are given on the same graph.

(v) There ate two x-intercepts, the one on the right is the larger one.

It is (0.732, 0), marked on the graph.

(vi) This function is the standard form of the given:

With the positive leading coefficient of 1, it has a minimum value but no maximum. The minimum of this function is at its vertex, which is (- 1, 3) as per graph.

(vii) The function y = x² + 2x is the translation of the given function up by two units.

So its minimum value is 2 units greater:

By definite integrals, we find that the area of the region bounded by the functions f(x) and g(x) described in the statement is equal to 4.5 units.

In this problem we must determine the area between two functions, a quadratic equation f(x) and a linear equation g(x).

First, we need to determine the limits of the interval of x-values with the help of a graphing tool, represented by the points of intersection of the two functions.

The points of intersection of the two functions are (x₁, y₁) = (- 5, 4) and (x₂, y₂) = (- 2, 1), respectively. Then, the area is defined by the following definite integral:

[tex]I = \int\limits^{-2}_{-5} {[g(x) - f(x)]} \, dx[/tex]

[tex]I = \int\limits^{-2}_{- 5} {[(- x - 1) - (x + 3)^{2}]} \, dx[/tex]

[tex]I = - \frac{1}{2} \cdot [(- 2)^{2} - (- 5)^{2}] - [(- 2) - (- 5)] - (1 / 3) \cdot [(- 2 + 3)^{3} - (- 5 + 3)^{3}][/tex]

I = - (1 / 2) · (4 - 25) - 3 - (1 / 3) · (1 + 8)

I = - (1 / 2) · (- 21) - 3 - (1 / 3) · 9

I = 21 / 2 - 3 - 3

I = 21 / 2 - 6

I = 21 / 2 - 12 / 2

I = 9 / 2

I = 4.5

The area of the region represented by the definite integral introduced above is equal to 4.5 units.

The statement leads to a contradiction. Correct form is presented below:

From the given parameters to determine the cost of the airline ticket, we can interpret that that the maximum amount that each ticket costs is $295 while the maximum amount of bags is 5 bags.

We are given the linear equation that represents the cost of an airline ticket after adding a number of checked bags as;

y = 145 + 30x

where;

y is the cost (in dollars) of an airline ticket after adding a number of checked bags

x is the number of checked bags

Thus, if there is a maximum of 5 bags that can be checked, then we have;

y = 145 + 30(5)

y = $295

This means that the maximum amount that each ticket costs is $295 while the maximum amount of bags is 5 bags.

Answer: 57.14 km/hr

Step-by-step explanation:  if an hour is divided into quarters it will be in increments of 15 minutes, since  one hour is 60 minutes.  60 minutes divided by 5 is 15 minutes.  

So 1 hour and 38 minutes is rounded off to 1 hour and 45 minutes.

this is 1 hour + 3/4 hour = 1 3/4 hour.  This is same as 1.75 hour

3/4 is .75

speed divided by the time will give the average speed.

100km/1.75hours  = 57.14 km/per hour

Answer:

(a)  1 hour 45 min

(b)  57.1 km/h (nearest tenth)

Step-by-step explanation:

Given information:

[tex]\large\boxed{\sf Speed=\dfrac{Distance}{Time}}[/tex]

[tex]\begin{aligned}\sf \dfrac{1}{4}\;hour &= \sf 1 \; hour \div 4 \\& = \sf 60 \;mins \div 4\\& = \sf 15 \; mins\end{aligned}[/tex]

Therefore, the nearest ¹/₄ hours either side of the given time is:

1 h 38 min 45 sec is 8 min 45 sec more than 1 hour 30 min.

1 h 38 min 45 sec is 6 min 15 sec less than 1 hour 45 min.

Therefore, the nearest ¹/₄ hour to the given time is:  

1 hour 45 min = 1.75 min (in decimal form)

Substitute the given distance and the rounded time (in decimal form) into the formula and solve for speed:

[tex]\begin{aligned} \implies \sf Speed & =\sf \dfrac{Distance}{Time}\\\\& = \sf \dfrac{100}{1.75}\\\\& = \sf 57.1\;km/h\;(nearest\;tenth)\end{aligned}[/tex]

The best estimate of the cost to ship 5 large packs is 94.75 and 3 small packages is 29.25.

What is the best estimate?

Best estimate means an income, expense, or circumstance prediction based on past amounts of income and expenses and known factual information concerning future circumstances which affect eligibility, expenses to be incurred; or income to be received in the benefit month.

Given that

Shipping company charges 18.95 for a large package.

Shipping company charges 9.75 for a small package.

For 5 large packs shipping company charges = 5 × 18.95 = 94.75

For 3 small packs shipping company charges = 3 × 9.75 = 29.25

Therefore,  the best estimate of the cost to ship 5 large packs is 94.75 and 3 small packages is 29.25.

To find the value of x and y, isolate it on one side of the equation.

-3x+2y=4, 4x=13y=5

-3x+2y=4

[tex]\rightarrow \sf{x=-\dfrac{4-2y}{3}}[/tex]

Substitute.

Add by 16 from both sides.

-16-31y+16=15+16

Solve.

Using it's formula, it is found that the bond's yield with a face value of $5,000, yield of 7% and rate of 8%, is of 7.48%.

The bond's yield is given according to the following formula:

Yield = Annual Coupon Payment/Bond Price

These values are calculated considering the face value, the current yield and the coupon rate, all parameters which are given in this problem.

The Annual Coupon Payment is given by the multiplication of the face value and the Coupon Rate, hence:

Annual Coupon Payment = 5000 x 0.08 = $400.

The bond price is the given by the multiplication of the face value and 100% plus the yield, hence:

Bond Price = 5000 x 1.07 = $5350.

The actual work is done by a calculator, as shown in the attachment.

The level of ibuprofen in the patients bloodstream increased from 0 hours to 2 hours.

What is ibuprofen?

Ibuprofen is an example of an NSAID that is used to relieve pain, fever, and inflammation. This includes menstruation pain, migraines, and rheumatoid arthritis. Additionally, it can be applied to seal off a premature infant's patent ductus arteriosus. It can be given orally or intravenously. After an hour, it usually begins to function.

In the graph that is attached, the y-axis represents the concentration of ibuprofen in the patient's bloodstream, and the x-axis represents the number of hours since ibuprofen was last consumed.

As we can see from the graph, the curve increases from a time of 0 hours, which corresponds to 0 mg of ibuprofen, to a time of 2 hours, which corresponds to 400 mg of ibuprofen.

The curve starts to descend after that point. We will settle for the first assertion because increase is what we are interested in.

Thus, we may conclude that the increase in ibuprofen level occurred between 0 and 2 hours.

Here, the given line x = -4 is a vertical line that is always at x = -4.

The slope of a vertical line is undefined.

Since x = -4 is a vertical line it means the slope is undefined.

The slope of a line perpendicular to a vertical line is always zero.

Also, the line perpendicular to a vertical line must be a horizontal line.

Therefore, since the perpendincular line passes the point (-1, 4), it means the line will be:
