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:

An equation, in point-slope form, that represents Byron's distance from home, y, after hours is: B. y - 4 = 6(x - 1/2).

The point-slope form can be defined as an equation which is used when the slope of a line and one of the points on this line is known.

Mathematically, the point-slope form of a line is given by this equation:

y - y₁ = m(x - x₁)

Where:

Given the following data:

Average speed (slope), m = 6 mi/h.

Point, y = 4.

Point, x = 1/2

Substituting the given parameters into the formula, we have;

y - y₁ = m(x - x₁)

y - 4 = 6(x - 1/2)

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.

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.

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.

You want 88 increased by 14% using the multiplier method.

The multiplier used to increase an amount by some fraction (p) of that amount is (1 +p). Here, the fraction is 14%, or 0.14. That means the multiplier is ...

  multiplier = 1 +p

  multiplier = 1 +0.14 = 1.14

The increased amount is then ...

Line (0, 2), (-5, -3) ---> y = x + 2

Line (0, 5), (-5, -5) ---> y = 2x + 5

Point of intersection ---> we need to equate both equations:

Solving the circumference function, we have that:

The corresponding interval for diameters of the washers is 1.85 ≤ d ≤ 1.97.

The circumference of a circle of diameter d is given by:

C = 3.14d.

As stated in the problem.

The interval of circumference values is:

5.8 ≤ C ≤ 6.2.

Hence the lowest possible value for the diameter is given by:

3.14d = 5.8

d = 5.8/3.14

d = 1.85.

The highest possible value for the diameter is given by:

3.14d = 6.2

d = 6.2/3.14

d = 1.97.

Then the compound inequality that completes the given sentence is:

1.85 ≤ d ≤ 1.97.

We know that the owner initially has a figure whose price is $20, and he sells it for $30.

Then, he sells it for a $100 bill, so he gives $70 back.

The problem is that the $100 bill was fake, so at this point the total amount that he loses is:

The value of the action figure (which is $20) plus the $70 that he gives back.

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 equation of the line that passes through the point (6,-5) and has a slope of -1/6 is y = (-1/6)x  - 4.

We know that, the slope intercept form of a line is given by:-

y = mx + c

Where,

m represents the slope of the line,

c represents the y -intercept and,

(x,y) represent the coordinates of each of the ordered pairs in the line

Hence, we can write,

m = -1/6

One of the ordered pairs, (x,y) is (6,-5).

Hence, we can write,

-5 = (-1/6)*6 + c

-5 = -1 + c

c = -5 + 1

c = - 4

a) m∠2 = m∠7

This is correct

m∠2 = m∠3 as they are vertically opposite angles

However, m∠3 = m∠7 as they are vertically opposite angles

b) m∠7 = m∠10

We cannot compare the relationship between b and c as the pair are not parallel lines

c) m∠8 = m∠9

This is not correct also as the pair of lines are not parallel

d) m∠4 = m∠8

Let's find the equation of the line that passes through the point and is perpendicular to the line x = -4.

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:

Step-by-step explanation:

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.

Solve.

Use the distributive property.

A(B+C)=AB+AC

A(B-C)=AB-AC

[tex]\sf{=\dfrac{-16-31y}{3}=5}[/tex]

Isolate the term of y.

Multiply by 3 from both sides.

[tex]\sf{\dfrac{3\left(-16-31y\right)}{3}=5*3}[/tex]

Solve.

Multiply the numbers from left to right.

5*3=15

-16-31y=15

Add by 16 from both sides.

-16-31y+16=15+16

Solve.

15+16=31

-31y=31

Divide by -31 from both sides.

-31y/-31=31/-31

Solve.

y=-1

Substitute of y=-1.
