Answer:

PM = 14.4

Step-by-step explanation:

In triangle MLK, PN || LK

Therefore, by Basic Proportionality Theorem:

[tex] \frac {PM}{PL} =\frac{15}{10}[/tex]

[tex] \frac {PL}{PM} =\frac{10}{15}[/tex]

(By invertendo)

[tex] \frac {PL+ PM}{PM} =\frac{10+15}{15}[/tex]

(By componendo)

[tex] \frac {LM}{PM} =\frac{25}{15}[/tex]

[tex] \frac {24}{PM} =\frac{5}{3}[/tex]

[tex]PM= \frac {24\times 3}{5} [/tex]

[tex]PM= \frac {72}{5} [/tex]

[tex]PM= 14.4 [/tex]

Answer:

PM = 14.4 units

Step-by-step explanation:

ΔKLM ≈ ΔNPM so we can write a proportion relating corresponding sides

LM / KM = PM / NM

24 / 25 = PM / 15

cross-multiply:

25·PM = 24(15)

25PM = 360

PM = 360 / 25

PM = 14.4

Answer:  

[tex]log_b(w^3y^4)[/tex]

Step-by-step explanation:

To write the expression as a single logarithm, or condense it, use the properties of logarithms.  

1) The power property of logarithms states that [tex]log_ax^r = rlog_ax[/tex]. In other words, the exponent within a logarithm can be brought out in front so it's multiplied by the logarithm. This means that the number in front of the logarithm can also be brought inside the logarithm as an exponent.  

So, in this case, we can move the 3 and the 4 inside the logarithms as exponents. Apply this property as seen below:

[tex]3log_bw+4log_by\\=log_bw^3+log_by^4[/tex]

2) The product property of logarithms states that [tex]log_axy = log_ax+log_ay[/tex]. In other words, the logarithm of a product is equal to the sum of the logarithms of its factors. So, in this case, write the expression as a single logarithm by taking the log (keep the same base) of the product of [tex]w^3[/tex] and [tex]y^4[/tex]. Apply the property as seen below and find the final answer.  

[tex]log_bw^3+log_by^4\\=log_b(w^3y^4)[/tex]

So, the answer is [tex]log_b(w^3y^4)[/tex].

Answer:

90

Step-by-step explanation:

the forumla of a triangle is base times height, divided by 2 and since it has a height of 12 and a base of 15, and if you multiply that it would give you 180, then divide by 2 since it is half a sqaure, which is 90

Answer:

[tex]3 \sqrt{41}[/tex]

Step-by-step explanation:

[tex]12^2 + 15^2 = x^2 \\x = \sqrt{369} = 3\sqrt{41}[/tex]

Answer:

Lol this is my first time seeing someone saying I bet no one will answer this. Ok coming back to the topic answers are :-

Initial value = -18

Initial value is the output value or the y variable. Looking in the table the y variable is -18 since x is 0.

Rate of change = 0.5

You have to use the formula of rate of change to find the answer. You can choose any pairs from the table and will give you the same answer. I pick the first pair and the last pair to find my rate of change.

(0, -18) and (36, 0)

x1, y1 x2, y2

Rate of change = y2 - y 1 / x2 - x1

Rate of change = 0 - (-18) / 36 - 0

Rate of change = 18 / 36

Rate of change = 0.5

Hope this helps, thank you :) !!

Answer: The age of the fossilized leaf is 13829 years.

Step-by-step explanation:

Expression for rate law for first order kinetics is given by:

[tex]t=\frac{2.303}{k}\log\frac{a}{a-x}[/tex]

where,

k = rate constant  

t = age of sample

a = let initial amount of the reactant = 100

a - x = amount left after decay process = [tex]\frac{18}{100}\times 100=18[/tex]  

a) for completion of half life:  

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

[tex]t_{\frac{1}{2}}=\frac{0.693}{k}[/tex]

[tex]k=\frac{0.693}{5600years}=0.00012years^{-1}[/tex]

b) for finding the age

[tex]t=\frac{2.303}{0.00012}\log\frac{100}{18}[/tex]  

[tex]t=13829years[/tex]

The age of the fossilized leaf is 13829 years.

The fossilized leaf is 13855 years old.

Half life is given by:

[tex]N(t)=N_o(\frac{1}{2} )^\frac{t}{t_\frac{1}{2} } \\\\Where\ N(t)\ is \ the \ value\ of\ the\ substance\ after\ t\ years,N_o\ is\ the\\original\ value\ and\ t_\frac{1}{2} \ is\ the\ half\ life[/tex]

Given that half life = 5600 years, N(t) = 18% of normal amount = 0.18N₀. Hence:

[tex]0.18N_o=N_o(\frac{1}{2} )^\frac{t}{5600} \\\\0.18=(\frac{1}{2} )^\frac{t}{5600}\\\\ln(0.18)=\frac{t}{5600}ln(0.5)\\\\t=13855\ years[/tex]

The fossilized leaf is 13855 years old.

11x_18=180

11x=180+18

11x=198

x=198÷11

x=18

Answer:

The angles are a linear pair.

x = 18

Step-by-step explanation:

The angles are a linear pair, meaning the angles add up to 180 degrees.

(9x - 15) + (2x - 3) = 180

11x - 18 = 180

11x = 198

x = 18

121/2 = 60.5

Thus, our answer is 60.5°

X = 60.5

Explanation

31+90= 121

121=2x

x=60.5

Answer:

14.3

Step-by-step explanation:

9/5= 9.2/x (cross multiply)

5 x 9.2= 46

46 ÷ 9 = 5.1

9.2 + 5.1 = 14.3

The length of AC is 14.3 cm.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Given that In the diagram of triangle ADC, EB || DC.

AE = 9, ED = 5, and AB = 9.2.

We need to find the length of AC.

To find the length of AC firstly we need to find BC.

This can be find by using proportionality.

AE/ED=AB/BC

9/5=9.2/x

Apply cross multiplication.

9x=9.2×5

9x=46

Divide both sides by 9

x=5.11

where x is BC which is 5.11

Now add AB+BC=AC

9.2+5.1=14.3

Hence, the length of AC is 14.3 cm.
