509 rounded to the nearest hundred would be 500

Answer:

509 rounded to the nearest hundred is:

500

Step-by-step explanation:

When rounding to the nearest hundred, like we did with 509 above, we use the following rules:

A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.

B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.

C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

Rounded to Nearest Hundred

Enter another number below to round it to the nearest hundred.

What is 510 rounded to the nearest hundred?

Now you know what 509 rounded to the nearest hundred is. Go here for the next number we rounded.

stephen wakes up late and runs to catch the bus, his running speed is 4m/s, he gets to the bus stop in 2 minutes. how many metre
Basile [38]
<span>Given:
s=4m/s
t=2m
d=?

Convert
1min=60sec

2 min x 60 sec / 1min = 120 sec

d=vt
= 4m/s * 120s
=  480 m


Example:
The given terms here are: Distance = 150 km Time = 7200 s Speed =?   To express the speed in appropriate units, in this given we can simply kilometer to meter which is the SI unit for distance. Hence, we do the conversion first. </span><span><span>
1.    </span>Conversion</span><span> 150 km = m? 1 km = 1000 m   150 km x 1000 m / 1 km = 150, 000 m   </span><span><span>
2.    </span>To find speed, we drive the formula d = vt where v = velocity or speed to v= d/t</span> 
<span>V = d / t </span>
<span>V = 150, 000m / 7200 s </span>
<span>V = 20.83 m/s </span>

Hence, 20. 83 m/s is the speed.<span>

Below is the graph of a trigonometric function. It intersects its midline at (3.7, 5) and again at (5.9, 5).
Flauer [41]

Answer:

4.4

Step-by-step explanation:

The parent function of this graph is:  y = sin(x)

The sine function is periodic, meaning it repeats forever.

Standard form of a sine function:

\sf f(x)= A \sin(B(x+C))+D

where:

  • A = amplitude (height from the mid-line to the peak)
  • 2π/B = period (horizontal distance between consecutive peaks)
  • C = phase shift (horizontal shift - positive is to the left)
  • D = vertical shift

The <u>period</u> is the horizontal distance between consecutive peaks, which is the same as <u>twice the horizontal distance between the intersection of the curve and the mid-line</u>.

Given consecutive points of intersection between the curve and the mid-line:

  • (3.7, 5)
  • (5.9, 5)

Therefore, the horizontal distance between these two points is:

5.9 - 3.7 = 2.2

⇒ Period = 2.2 × 2 = 4.4

-------------------------------------------------------------------------------------

To create the equation for the function.

From inspection of the given graph:

  • Amplitude (A) = 6
  • Mid-line is y = 5
  • Vertical shift (D) = +5

Period = 2π/B = 4.4  ⇒  B = 5π/11

Phase Shift (C) = -3.7

Substituting the values into the standard form:

\implies \sf f(x)= 6 \sin\left(\dfrac{5}{11}\pi(x-3.7)\right)+5

\implies \sf f(x)= 6 \sin\left(\dfrac{5}{11} \pi x-\dfrac{37}{22}\pi \right)+5
