Answer:

x² + y² = 6

Step-by-step explanation:

The standard form of the equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

Here r = [tex]\sqrt{6}[/tex] , then

x² + y² = ([tex]\sqrt{6}[/tex] )² , that is

x² + y² = 6

Answer:

1/6 are oranges bc if half are apples 1/2 and 1/3 is bannas we need to make those fraftions match so we multiply 1/2 by 3 and 1/3 by 2 giving us a fraction over 6 which then we add what we already know so 3/6 is apples and 2/6 is bannas we add them together we get 5/6 which leaves us with 1/6 oranges

Answer:

17.28

Step-by-step explanation:

Totall buses: 48+28 = 72

% Of single decker: 72×(24÷100) = 17.28

Approximately 33.33 percentage of the buses in the depot are single-decker buses.

To find the percentage of single-decker buses, we need to calculate the ratio of the number of single-decker buses to the total number of buses (single-decker and double-decker) and then multiply by 100.

The total number of buses in the depot is given as 48 double-decker buses + 24 single-decker buses = 72 buses.

The number of single-decker buses is 24.

The ratio of single-decker buses to the total number of buses is 24 buses / 72 buses = 1/3.

To find the percentage, we multiply the ratio by 100:

(1/3) * 100 = 33.33%

Therefore, approximately 33.33% of the buses in the depot are single-decker buses.

Answer:

y inverse = √(x + 36)

Step-by-step explanation:

inverse of y = x² - 36

=> x² = y + 36

=> x = √(y + 36)

interchange x and y

=> y = √(x + 36)

P(E) = 0.5

P(A) = 0.2

P(N) = 0.3

Conditional probability ;

0.47

Step-by-step explanation:

Let :

E = Excellent ; A = Average ; N = not up to standard

P(E) = 0.5

P(A) = 0.2

P(N) = 0.3

If Leo shows up ; this type of probability is called a conditional probability. It is the likelihood of an event based on a certain or already satisfied condition.

The probability that Leo is coming :

Leo ; Excellent = 0.7

Leo ; Average = 0.3

Leo; Not up to standard = 0.2

Hence, probability they Leo is coming :

(0.5 * 0.7) + (0.2 * 0.3) + (0.3 * 0.2)

0.35 + 0.06 + 0.06

= 0.47

Differential equation is a way to represents the function and its variable by relating them.Hence the differential equation that describe the relationship between S and T is,

[tex]S \propto \dfrac{1}{log_e T}[/tex]

Given-

The quantity of S increases, the quantity of T decreases.

The rate of change of the quantity of S with respect to the  quantity of T present is inversely proportional to the natural logarithm of the quantity of T.

Differential equation is a way to represents the function and its variable by relating them.

As the quantity of S changes with respect to the  quantity of T present is inversely proportional. Thus,

[tex]S \propto \dfrac{1}{T}[/tex]

But quantity of S changes inversely proportional to the natural logarithm of the quantity of T. The natural logarithm of a  number is its logarithm to the base of e (constant).

Thus the equation can be given is,

[tex]S \propto \dfrac{1}{log_e T}[/tex]

Hence the differential equation that describe the relationship between S and T is,

Answer: 856.59 km/h

Step-by-step explanation:

Length of a planet's orbit around a star = 17,680,000 km.

Days to complete full orbit = 860 days

Number of hours to complete full orbit = 860 × 24 hours = 20640 hours

The planets average speed in km/h will be:

= Distance / Time

= 17,680,000 / 20640

= 856.59 km/h

Answer:

  (x +10)(x -4)

Step-by-step explanation:

Compare the factored and expanded forms:

  (x +p)(x +q) = x^2 +(p+q)x +pq = x^2 +6x -40

That is, the constants in the binomial factors will be factors of -40 that have a sum of 6. This is where your knowledge of multiplication tables is helpful.

  -40 = -1×40 = -2×20 = -4×10 = -5×8

The sums of these factor pairs are 39, 18, 6, 3, respectively. So, the one we want is (-4)(10) = -40. Now that we know the values of 'p' and 'q', we can write the factorization ...

  x^2 +6x -40 = (x -4)(x +10)
