Step-by-step explanation:

 (4/3)P -(4/3)A + A = B . . . . . . add A

 (4P -A)/3 = B . . . . . . . . . . . . . simplify

Then the coordinates of point B are ...

 B = (4(1, 6) -(-5, 3))/3 = (9, 21)/3

 B = (3, 7)

The longest possible length of the thread is;

Length = 144 cm

Now, it is first folded in half. This means divided into 2. Thus, we now have length as x/2.

This means the ratio is; 8:18

longer length will be; [tex](\frac{18}{8 + 18})[/tex] [tex]* (\frac{x}{4})[/tex]

Thus, we now have;

18 = (18/26) × (x/4)

18 will cancel out to give; x = 26 × 4

x = 144 cm

Therefore the longest possible length of the thread = 144 cm

Here's the solution :

therefore , correct choice is B

Answer:

B. 1.5

Step-by-step explanation:

To turn a fraction into a decimal, make the denominator (the bottom number) 100 since you are only using the tenths place of a decimal:

1/2 x 50/50 = 50/100 = 0.5

Then add the whole number:

1 + 0.5 = 1.5

Answer:

f(x) = x² - 5

so f(0) = 0² - 5 = 0 - 5 = - 5

and f(3) = 3² - 5 = 9 - 5 = 4

Answer:

Step-by-step explanation:

1. To find  a rational number between two numbers, divide the sum of the number by 2,

(1/4 + 1/2) × 1/2

=> [ (2 + 1)/4] × 1/2

=> 3/4 × 1/2

=> 3/8

3/8 is a rational number between 1/4 and 1/2

3. any positive number is greater than a negative so 1 2 3 4 5 6 7 8 9 and -2

Answer:(1/4 + 1/2) × 1/2

=> [ (2 + 1)/4] × 1/2

=> 3/4 × 1/2

=> 3/8

3/8 is a rational number between 1/4 and 1/2

Answer:

21

Step-by-step explanation:

You can write this question out with two separate formulas, the first one being H - 5 = T, and the second being H + T = 57. I am using the variables of H and T to show the ages of Hulian and Thomas respectively. From here, we can use the substitution formula since we already know what T is equal to (H - 5). Substituting the equation in, we get a new equation of H + (H + 5) = 57. Subtracting 5 from both sides gives us the equation of H + H = 52, or 2H = 52. Dividing by 2 yields the answer of 26 for Hulian's age. Since we know that Hulian is 5 years older than Thomas, we can subtract 5 from 26, giving us Thomas' age, which is 21.

Answer:

23.5

Step-by-step explanation:

=57/2

Answer: Sin(©)=4/5

Step-by-step explanation: Cos(©)=3/5

Sin(©)=?

By Trigonometric identity,

Sin²(©) + Cos²(©) = 1

Sin²(©) = 1- Cos²(©)

Cos²(©) = (3/5)² = 9/25

Sin²(©) = 1- 9/25 = 16/25

Taking the root of both sides,

√(Sin²(©)) = √(16/25)

Hence, Sin(©) = 4/5

Answer:

3 teachers and 9 tutors

Step-by-step explanation:

Answer:

There are 24 students per teacher and 8 students per tutor. If the academy has 72 students, then 9 tutors would be needed.

Step-by-step explanation:

We will start with the question, how many students does the academy have per teacher. To find this, we need to set up the equation. 144 will be the number of students, 6 will be the number of teachers, and x will be the number of students per teacher.

144/6=x

24=x

So, there are 24 students for every teacher.

We could also do this as a ratio. We would do the same thing. We would divide by six to get our answer.

144:6

Make the six one.

24:1

This shows that there are 24 students for every teacher.

Now to find out how many per tutor.

We will do the same thing as before, minus the ratio, though you could still use the ratio. Remember, 40 is the number of students, 5 is the number of tutors, and x is the number of students per tutor.

40\5=x

8=x

So there are 8 students per tutor.

Now we will use this knowledge to solve for how many tutors are needed if the academy has 72 students.

We will set up our equation. 72 will be the students, we will use eight since that is how many students are needed per tutor, and x will be the number of tutors needed.

72/8=x

9=x

So this means that if the academy has 72 students, then it will need 9 tutors.

Answer:

1. 3D-1200 = value after two years.

2. $1800 = value after two years

Step-by-step explanation:

When the value of D triples, 3 times D = 3D. value of the stock after two years decreased, would be the -1200.

When you get the value of 1,000 you can plug it in to get 3 (1000) - 1200 = Stock price after two years

Random sampling involves selecting a sample where each element of the sample have an equal probability of selection.

From the question, we understand that the director wants to make use of a stratified random sampling technique.

The stratified random sampling technique involves selecting the sample (i.e. 100 students), by dividing the whole undergraduate students into groups (i.e. strata), and then select a proportion from each group.

A possible way to achieve this, is as follows:

With the above highlights, the director would be able to make the selection.

Answer:

-0.584 rad/hr, rounded to the nearest 1000th  

Step-by-step explanation:

Let D = D(t) = the horizontal distance from the observer to the plane at time t in units of km.  

Let E = E(t) = the angle of elevation at time t in units of Radians.

Then, by geometry,

tan(E) = 16 / D, and furthermore, we have that

tan(E) = 16 * D^(-1)

d/dt (tan(E)) = d/dt ( 16 * D^(-1))

sec^2 (E) * dE/dt = 16(-1)(D^(-2)) * dD/dt

( sqrt(D^2 + 16^2) / D )^2 * dE/dt = -16 (D^(-2)) * dD/dt

(D^2 + 16^2)/D^2  *  dE/dt = -16 (D^(-2)) * dD/dt

dE/dt = -16 (D^(-2)) * dD/dt * D^2 / (D^2 + 16^2)

dE/dt = -16 (dD/dt) / (D^2 + 16^2)

dE/dt = -16 (580 km/hr) / (125^2 + 16^2), at time t such that D(t) = 125 km,

dE/dt = (-9280 / 15881) rad/hr

dE/dt = -0.584 rad/hr, rounded to the nearest 1000th
