As we have shown that both line segments PN and PM are equal to (1/2)MN, and hence they are equal in length to each other.

Given that point P lies on the perpendicular bisector l of line segment MN, we know that line segment PN and line segment PM are both equal in length to the distance between point P and the midpoint of MN, which we will call point O. This is because the perpendicular bisector of a line segment passes through the midpoint of the segment, and any point on the perpendicular bisector is equidistant from the endpoints of the segment.

Let us call the length of line segment PM "x". Then, we can express the lengths of line segments PN and PO in terms of x as well. Since P is equidistant from the endpoints of MN, we know that line segment PN has the same length as line segment PO, which is half the length of MN. We can express this relationship mathematically as:

PN = PO = (1/2)MN

Similarly, we can express the length of line segment PM in terms of the length of PO, which is also equal to (1/2)MN. Since line segment PM is equal in length to the distance between point P and the midpoint of MN, we know that:

PM = PO = (1/2)MN

Therefore, we have proved that PM = PN.

The reasonable domain to plot the growth function is {x : 0 ≤ x ≤10}.

y intercept of the graph of the function represents the initial height of the plant.

Average rate of change of the function f(n) from n = 3 to n = 10 is 0.43.

Given a growth function,

f(n) = 12 (1.03)ⁿ

Part A :

When the scientist concluded his study, the height of the plant was approximately 16.13 cm.

12 (1.03)ⁿ = 16.13

(1.03)ⁿ = 1.344

Taking logarithms on both sides,

n log (1.03) = log (1.344)

n = log (1.344) / log (1.03)

n = 10.006 ≈ 10 days

Domain = {x : 0 ≤ x ≤10}

Part B :

The y intercept of the graph of the function is the height of the plant in 0 days, that is the initial height of the plant.

Part C:

Average rate of change of the function f(n) from n = 3 to n = 10 is,

f(10) - f(3) / 10 - 3

f(10) = 12(1.03)¹⁰ = 16.127

The total remaining length of road that needs to be paved after the four days is: b). 1 5/6.

In order to determine total remaining length of road that needs to be paved after the four days, we would evaluate and simplify the fraction for the expressions as follows;

Length of road paved in four days = 35/6  + 39/6  + 52/6  + 25/6

Length of road paved in four days = (35 + 39 + 52 + 25)/6

Length of road paved in four days =  151/6

Step-by-step explanation:

The statement that is true about histograms is that data is organized in equal intervals. Histograms are graphical representations of data that use bars to show the frequency of values in a continuous range. The bars are of variable heights depending on the frequency of data within each interval, but the width of each bar represents the same interval size. This allows for easy comparison between different intervals and helps to visualize the distribution of data. It is important to note that the bars in a histogram do touch, as they represent continuous data ranges.

Answer:

C) 12/9 = 4/3

Step-by-step explanation:

it is a right-angled triangle.

Pythagoras applies.

cos(theta) = 9/15

that is the horizontal leg in relation to the baseline (Hypotenuse).

since we are only dealing with ratios here, to get the vertical leg and its relation to the Hypotenuse, we can simply use the numbers of the ratio.

15² = vleg² + 9²

225 = vleg² + 81

vleg² = 144

vleg = 12

therefore,

sin(theta) = 12/15

tan(theta) = sin(theta)/cos(theta) = 12/15 / 9/15 = 12/9 = 4/3

FYI : to prove to you how irrelevant the absolute lengths in ratios are, here a variation with simplified fractions or ratios :

cos(theta) = 9/15 = 3/5

5² = vleg² + 3²

25 = vleg² + 9

vleg² = 16

vleg = 4

therefore,

sin(theta) = 4/5

tan(theta) = sin(theta)/cos(theta) = 4/5 / 3/5 = 4/3

as you see, all as above.

for these kind of calculations we only need ratios (or relative sizes)

Answer:

800 grams flour ÷ 5 grams flour/biscuit = 160 biscuits

160 biscuits × 3 grams butter/biscuit = 480 grams butter

160 biscuits × 2 grams sugar/biscuit = 320 grams sugar

Katie needs 320 grams sugar.

Kate needs 270g of sugar to make the maximum number of biscuits possible.

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Now, Based on the ratio of flour, butter, and sugar of 5:3:2, we can determine that Kate needs;

⇒ 800g + 550g

= 1350g of the mixture.

Hence, For find out the amount of sugar needed, we need to determine the proportion of sugar in the mixture.

We can do this by adding up the ratio numbers;

(5+3+2) = 10.

Then we can divide each ratio number by the total (10) to get the proportion of each ingredient.

So the proportion of sugar in the mixture is 2/10. To find out how much sugar Kate needs, we can set up a proportion:

2/10 = x/1350

We can solve for x by cross-multiplying:

2 × 1350 = 10x

2700 = 10x
x = 270

Therefore, Kate needs 270g of sugar to make the maximum number of biscuits possible.

Where:

N(t) is the population size at time t

N is the initial population size (at t = 0)

r is the growth rate parameter

t is the time elapsed

We want to find the time t it takes for the population size to double, which means N(t) = 2N. Substituting into the growth model, we get:

[tex]2N = N * e^{rt}[/tex]

Dividing both sides by N, we get:

The number of minutes of local landline calls is 132 min.

We are given that;

Time= 36min

Bill= 13119

Now,

To find the number of minutes of local landline calls, we need to rearrange the tariff structure formula to solve for n in terms of Total and m. We also need to substitute the given values of Total and m.

Total = nx 12c/min +mX R1,10/min + R75,75

n = (Total - m x R1,10/min - R75,75) / (12c/min)

Total = R131.19

m = number of minutes of calls to cellphones = 36 min

n = (131.19 - 36 x 1.10 - 75.75) / 0.12

= (131.19 - 39.60 - 75.75) / 0.12

If the 2 boxes are stacked on top of other, then the total volume of both boxes will be (b) 224m³.

To find the total volume when two boxes are stacked on top of each other, we need to add the volume of both boxes. The formula for the volume of a rectangular box is : Volume = Length x Width x Height,

Using the dimensions, that Length = 8m, Width = 7m and height = 2m,

The volume of the first-box is:

⇒ Volume1 = 8m × 7m × 2m = 112 cubic meters,

The volume of the second-box will be the same, because it has the same dimensions;

So, Volume2 = 8m × 7m × 2m = 112 cubic meters,

To find the total volume when the boxes are stacked, we add the volumes:

⇒ Total Volume = Volume1 + Volume2,

⇒ Total Volume = 112 cubic meters + 112 cubic meters,
