What is 5.2x10^4 in standard form

1 answer:

52,000

You take the decimal, and because something is to the tenth or after the decimal, it counts as one of the parts of the exponent. You add 3 zeros because you are left with 3 after the .2 is shown.

So you would have 52000

A hiker cycles 9 miles in 2/3 of an hour. Make a chart and fill it in to show how far he will bike if he maintains the same pace

Arada [10]

Answer:

2 hours: 27 miles, 3 hours: 40.5 miles, 3.5 hours: 47.25 miles

Step-by-step explanation:

1.) If a hiker hikes 9 miles in 2/3 of an hour, he will hike 4.5 (Half of 2/3 is 1/3 and half of 9 is 4.5) miles in 1/3 of an hour and 13.5 miles per hour. (1/3 times 3 gives us a whole and 4.5 times 3 is 13.5)

2.) 2 hours: 13.5 * 2 = 27 miles

3.) 3 hours: 13.5 * 3 = 40.5 miles

4.) 3.5 hours: 13.5 * 3.5 = 47.25 miles

If (x) = 3x - 5 and g(x) = x + 3, find (f - g)(x).

Temka [501]

Answer:

2x -8

Step-by-step explanation:

f (x) = 3x - 5

g(x) = x + 3,

(f - g)(x) = 3x - 5 - ( x+3)

Distribute the minus sign

= 3x-5 -x-3

Combine like terms

= 2x -8

In a certain region, 6% of a city’s population moves to the surrounding suburbs each year, and 4% of the suburban population mov

Charra [1.4K]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

Following are the differential equation:

$\to P(C,S)t+1 = P(C,S)t+(- 0.06Ct +0.04St, 0.06Ct - 0.04St ) \ \ \ \\\\or \ \ \ \ \ \ \ \\\\ \to (0.94Ct + 0.04St, 0.96St + 0.06Ct)$

In equation:

$\to t = 0, \ as \ 2019\\\\\to Ct = 10,000,000 \\\\\to St = 800,000,000\\$

$\to P(C, S)1 = (0.94Ct + 0.04St, 0.96St + 0.06Ct) \\\\$

$= (0.94(10000000) + 0.04(800000), 0.96(800000) + 0.06(10000000))\\\\ = (9,400,000 + 32,000), (768,000 +6000000))\\\\ = (9432000, 1368000)$

$\to P(C, S)2 = (0.94(9432000) + 0.04(1368000), 0.96(1368000) + 0.06(9432000))$

$=(8,866,080 + 54,720), (1,313,280 + 565,920)\\\\=(8,920,800, 1,879,200)$

What is the area of the trapezoid?<br> 5 cm<br> 14 cm<br> 5 cm<br> 10 cm

prisoha [69]

Answer:

A = 28 cm

Step-by-step explanation:

equation:

A = $\frac{a + b}{2} h$

A = $\frac{4 + 10}{2} 4$

solve:

A = $\frac{14}{2}4$

A = 7 x 4

A = 28 cm

4. How much time will it take for a bug to travel 7.5 meters across the floor if it is traveling at 1 m/s?

scZoUnD [109]

It will take the bug 7.5s to travel across the floor.

Step-by-step explanation:

Distance = 7.5 meters

Speed = 1 m/s

The formula for speed is

$Speed = \frac{Distance}{Time}\\\\Time = \frac{Distance}{Speed}\\Time=\frac{7.5}{1}\\Time=7.5\ s$

It will take the bug 7.5s to travel across the floor.
