Answer:

B. 8 x 10^3

Step-by-step explanation:

1.6 x 10^5 / 0.2 x 10^2

= 160 000 / 20

= 8 000

You can write this as 8 x 10^3

Why is the slope of this graph?

Tom [10]

Answer:

1/2.

Step-by-step explanation:

There seem to be a couple prominent points on the line. We can use two of them to find the slope.

(0, 75)

(30, 90)

(90 - 75) / (30 - 0) = 15 / 30 = 3 / 6 = 1/2.

Hope this helps!

1. June says that there should be a decimal point in the quotient below after the 4. Is she correct? Use number sense to explain

charle [14.2K]

43.94 / 5.2 = 845 is impossible because it would mean that 845 * 5.2 is equal to 43.94 which would be a non sense.

Even if you multiply 84.5 * 5.2 you will still get a bigger result than 43.94 obviously.

The only way this division would make sense, it is if the result is 8.45 so the decimal point should be before the 4 and not after it so June is not correct.

GOod luck :)

A hockey player strikes a hockey puck. The height of the puck increases until it reaches a maximum height of 3 feet, 55 feet awa

MariettaO [177]

Answer:

The maximum height of the second pluck is greater than that of the first pluck, hence the second pluck travels further

Also the distance of the maximum height of first pluck from the player is less than the distance of the second pluck from the player hence the second pluck travels further

Step-by-step explanation:

From the question we are told that

The maximum height of the first pluck is $h_1 = 3 \ ft$

The height of the second height is mathematically represented as

$$y=x\left(0.15-0.001x\right)$

=> $y=0.15x -0.001x^2$

Generally at maximum height $y' = 0$

$y'=0.15 -0.002 x = 0$

=> $x = 75 \ ft$

Here 75 ft is the horizontal distance the second pluck traveled at maximum height

So the maximum height of the second pluck is mathematically represented as

$y=0.15(75) -0.001(75)^2$

=> $y= 5.625 \ ft$

So comparing the maximum height of the first and the second pluck we see that the maximum height of the second pluck is greater than that of the first pluck, hence the second pluck travels father

An earthquake near the Philippines measured 5.1 on the Richter scale. Use the formula R=log(A/Ao) to determine approximately how

hammer [34]

Answer:

If R is equal 5.1, Let x be A/A0

Then we have logx=5.1

Solving this we have x=125893
