Answer:

\(\huge\boxed{\sf -2.280}\)

Step-by-step explanation:

Finding value of log₃(4/49):

\(\displaystyle = log_{3}\frac{4}{49} \\\\= log_{3} (\frac{4}{7^2} )\\\\\underline{Using \ log \ rule \ :} \ log( \frac{a}{b} )= log \ a - log \ b \\\\= log_{3}4 - log_{3}7^2\\\\\underline{Using \ log \ rule \ : } \ log \ a ^m = m \ log \ a \\\\= log_{3}4 - 2(log_{3}7)\\\\\)

Given that:

log₃4 ≈ 1.262, log₃7 ≈ 1.771

Put the values in the above expression

\(= 1.262-2(1.771)\\\\= 1.262 - 3.542\\\\= \bold{-2.280}\\\\\rule[225]{225}{2}\)

The statement that is true about Scientific process and method is the scientific process is a continuous process of collecting data and refining hypothesis.  

Studies and researches are done by a scientific method which follows certain standards and protocols. The method starts with an observation, a question is asked why it happens and formulating a hypothesis. Either we can do a controlled experiment to test whether the hypothesis is correct or not, or we can do a non-experimental hypothesis, where experimenting will not be ethical.

The scientific process is a continuous process, which need to be collecting data and refining hypothesis. Even our data support hypothesis, the data might not be true in some cases. So work on a scientific concept is never complete. Even if we have data on causes and effects of a natural phenomena, we could not necessarily predict it every time, example: earthquake. Also, while collecting data, we should be fair in its treatment. We can't take data that only support our hypothesis.

So, the correct statement is option c. Scientific process is a continuous process of collecting data and refining hypotheses.

Answer:

x=1 x=-11

Step-by-step explanation:

first you need to find what two numbers add together to make 10x and multiply together to make 25-

this would be 5

so we can rewrite it as (x+5)(x+5) = 36

which is the same thing as (x+5)^2 =36

then taking the root of both sides we get (x+5)= plus or minus 6

so x=-11 or x equals 1

Based on the formula of the quadratic function y=-x^2+6x-5, we know that its graph is a downward-facing parabola that opens wide, with a vertex at (3,-14), and an axis of symmetry at x=3.

Based on the formula of the quadratic function y=-x^2+6x-5, we can determine several properties of its graph, including its shape, vertex, and axis of symmetry.

First, the negative coefficient of the x-squared term (-1) tells us that the graph will be a downward-facing parabola. The leading coefficient also tells us whether the parabola is narrow or wide. Since the coefficient is -1, the parabola will be wide.

Next, we can find the vertex using the formula:

Vertex = (-b/2a, f(-b/2a))

where a is the coefficient of the x-squared term, b is the coefficient of the x term, and f(x) is the quadratic function. Plugging in the values for our function, we get:

Vertex = (-b/2a, f(-b/2a))

= (-6/(2*-1), f(6/(2*-1)))

= (3, -14)

So the vertex of the parabola is at the point (3,-14).

Finally, we know that the axis of symmetry is a vertical line passing through the vertex. In this case, it is the line x=3.

Akash estimate of 700cm of plastic trim is not sensible because he needs more than that.

The diagram of the question is below.

The window is made of a semi circle and a rectangular. More like a composite figure.

Composite figure are 2 dimensional figures that combines two or more two dimensional figures. Therefore, the part the plastic trim was applied are those sharp line region. It's like finding the perimeter of the whole shaded region.

He estimate he will need 700 cm of plastic trim in total. Therefore, let check if his estimate is sensible.

Therefore,

radius = 59 cm

perimeter of the rectangle = 2(113) + 2(118) = 462 cm

perimeter of the semi circle = 3.14 × 59 = 185.26 cm

Two radius = 2(59) = 118 cm

Therefore,

The multiplication of 5 whole numbers is 16875

Given that

5 positive whole numbers add up to 47

we solve these by using system of equation  

let 5 whole numbers be p, q, r, s and t

equation is: p + q + r + s + t = 47

one of the number is a multiple of 9 the other four numbers are equal  

let p be the multiple of 9

equation is: p + q + q + q = 47

p + 4q = 47

let's try trial and error method q and p are whole numbers, they cannot be decimal  

let p = 9

9 + 4q = 47

4q = 47-9

4q = 38

q = 9.5 it is not whole number, so this is not the number

let p= 18

18 + 4q = 47

4q = 47-18

4q = 29

q = 7.25 it is not whole number, so this is not the number

let p = 27

27 + 4q = 47

4q = 47 -27

4q = 20

q = 5

then multiplication of these 5 whole numbers is

27 * 5*5*5*5 = 27*625=16875

The probability of an event tells us the chances and if it is maximum or 1 then the event will be a sure event.

The probability of an event occurring is defined by probability.

Probability is the chances of an event occurring in real life example if we toss a coin then the chances of coming head or tell are equal so the probability will be 50% or 0.5.

The mathematical form of probability stands for the number of desired outputs ÷ total number of outputs.

The probability ranges between 0 to 1.

0 means the event cannot happens for example probability of coming 6 in a flipping coin.

1 means the event will definitely happen for example if we have a coin in which both sides are heads then the probability of coming head will be 1.

This type of event in which probability is 1 is called a sure event.

Hence "The probability of an event tells us the chances and if it is maximum or 1 then the event will be a sure event".

Answer:

8 2/3

Step-by-step explanation:

First, we turn 6 1/2 into an improper fraction, which is 13/2. Now, we can write this out as: 13/2  divided by 3/4. When dividing fractions, you reverse the sign to multiplication and you flip the numerator and the denominator of the second number. So, in this case, it would be 13/2 TIMES 4/3 which now we can do! 13*4 is 52 and 2*3 is 6. 52/6 is a number we can simplify. We can divide out a 2, so 52/2 is 26 and 6/2 is 3. 26/3 can be put into a mixed number. 3 goes into 26, 8 times and there is a 2 left over. So our final answer is 6 2/3.

Step-by-step explanation:

1) 16x25x15 is 16 times 25 times 15, which is 6000

Let’s consider city A as the origin, and let’s define the plane’s displacement in terms of the final point from the starting point.457 km East is represented as +457 km in the x-direction. 890 km South is represented as –890 km in the y-direction.

(a) Magnitude of the plane's displacement: We can use the Pythagorean theorem to calculate the magnitude of the displacement.s = √((Δx)² + (Δy)²)

Where Δx = +457 km and Δy = –890 km.

s = √((+457)² + (–890)²) = 1000 km The magnitude of the plane’s displacement is 1000 km.

(b) Direction of the plane’s displacement: We can use the inverse tangent function to calculate the direction of the displacement. θ = tan⁻¹(Δy / Δx)

Where Δx = +457 km and Δy = –890 km.

θ = tan⁻¹(–890 / 457) = –61.3° The direction of the plane’s displacement is 61.3° South of West.

(c) Magnitude of the plane’s average velocity:To calculate the average velocity, we can divide the displacement by the total time taken. Δt = 42.0 min + 1.40 h = 1.40 h Average velocity, v = Δs / Δt = (1000 km) / (1.40 h) = 714 km/h The magnitude of the plane’s average velocity is 714 km/h.

(d) Direction of the plane’s average velocity:We can use the inverse tangent function to calculate the direction of the average velocity.θ = tan⁻¹(vy / vx)Where vx = 457 km / (42.0 min / 60 min/h) = 653 km/h and vy = –890 km / 1.40 h = –636 km/h.θ = tan⁻¹(–636 / 653) = –46.9°The direction of the plane’s average velocity is 46.9° South of West.

(e) Average speed of the plane:Average speed is calculated by dividing the total distance by the total time taken. Total distance = 457 km + 890 km = 1347 km Total time = 42.0 min + 1.40 h = 2.33 h Average speed = Total distance / Total time = 1347 km / 2.33 h = 579 km/hThe average speed of the plane is 579 km/h.
