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:
y(-4) = (-4 + 1)² - 3 = 9 - 3 = 6 maximumy(-2) = (-2 + 1)² - 3 = 1 - 3 = - 2 minimumThese 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:
(x + 1)² - 3 = x² + 2x + 1 - 3 = x² + 2x - 2With 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:

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.

What type of linear equation is X +1 equals X +1?
X+1 depicts horizontal linear equation as x = -1 and slope = 0.
Given that the slope is 0, it shows a horizontal linear equation.
Every point on a horizontal line has the same y-coordinate.
If two points have the same y coordinate, b, then the line's equation is y=b.
The y-intercept of the horizontal line y=b is the point (0,b). The line y=0 is the only x-intercept for horizontal lines.
Horizontal lines have zero slope.
As a result, in the slope-intercept equation y = mx + b, m = 0. The equation is Y = b, where b is the y-coordinate of the y-intercept.
A line that is perpendicular to the x-axis is referred to as a horizontal line.
The graph of a relation of the form x = 5 is a line parallel to the origin since the value of x never changes.

Find the area of the region that is bounded above by the curve f(x)=(x+3)2 and the line g(x)=−x−1 and bounded below by the x-axis.
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.
How to determine the area of the region bounded by two curvesIn 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]

I = 21 / 2 - 6
I = 21 / 2 - 12 / 2

A car travels a distance of 100km for 1h38min45sec.a)Round off the time to the nearest 1/4 hour b)Use the rounded time to find the average speed for the journey
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:
Distance = 100 kmTime = 1 h 38 min 45 sec[tex]\large\boxed{\sf Speed=\dfrac{Distance}{Time}}[/tex]
Part (a)[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 hour 30 min1 hour 45 min1 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.Part (b)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]

model to the length of an actual tile? What is the ratio of the area of a tile in the model to the area of an actual tile? Use
pencil and paper. Describe two ways to find each ratio.
The ratio is 1:8 and 1:64
Since each tile is one sixth of an inch in width and one fourth of an inch in length.
That is L1= 1/4 in addition to W1= 1/6 inches.
The real tiles are one sixth of a foot long and one tenth of a foot wide.
Since 1 foot equals 12 inches, that is in inches and inches. that is L2=2 and W2= 4/3
So, the length of the tile divided by its real length is equal to L1/L2
=(1/4)/2= 1/8
In addition, the relationship between the area of the tile in the model and the real area is given by:
(1/4 x 1/6)/ 2 x 4/3
= 1/64
Second method
Since there is a 1/8 ratio between the width of the model's tiles and their real width
As a result, there is dilatation with a scale factor of 1/8.
By virtue of dilatation, their area ratio = (1/8)^2 =1/64.

Solve the system of equations by multiplying. -3x +2y= 4 4x-13y=5
Answer:
x=-2 and y=-1Step-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.
[tex]\sf{4\left(-\dfrac{4-2y}{3}\right)-13y=5}[/tex]
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.
[tex]\sf{x=-\dfrac{4-2\left(-1\right)}{3}}[/tex]
Solve.
Use the order of operations.

What is the greatest number of sweets that
can be bought with $2 if each sweet costs
30 cents?
Answer:
6 sweets
Step-by-step explanation:
add 30 until you are going over
You need to purchase supplies for the trip. You have $1000 to spend.
Oxen: $40 each
Food: $0.20 per lb
Clothing: $10 per set.
Matt also charges 7% tax
Purchase at least 2 oxen, 500lbs of food, and 5 sets of clothing. You may want to purchase more.
Select the amount of items and find the total cost including tax.
The total cost of purchasing the minimum quantities for the trip, including sales tax of 7% is $246.10, while you can buy 4 times more.
What is a sales tax?A sales tax is a use or consumption tax, indirectly levied by the government on buyers of certain taxable items.
The seller collects the sales tax on behalf of the government.
Total amount to spend on supplies = $1,000
Items Cost Unit Units Total Units Total for more
Oxen: $40 each 2 $80 8 $320
Food: $0.20 per lb 500 100 2,000 400
Clothing: $10 per set 5 50 20 200
Total cost before tax $230 $920
7% sales tax $16.10 64.40
Total cost after tax $246.10 $984.40
Change = $15.60
Thus, with $1,000, you can purchase 4 times the above quantities and still have some change after paying the required sales tax.
