Answer:

37, 700, 000

Step-by-step explanation:

377(10,000) = 377 x 10,000

= 37, 700, 000

an easy way to see it is to just add the number of zeros from 10,000 to 377. since there are four zeros, you put four zeros behind 377.

Find three consecutive numbers whose sum is 84

mrs_skeptik [129]

Answer:

27 28 29

Step-by-step explanation:

Let the first be n , and if they are consecutive then the next two numbers are n+1 and n+2.

n+(n+1)+(n+2)=84.

3n+3=84.

⇒3n=81.

⇒n=27.

Hence numbers are n,n+1,n+2→27,28 and 29

If xy + x = 12 and dx/dt = -3, then what is dy/dt when x = 2 and y = 5?

dlinn [17]

If $xy + x = 12$ , then
$\dfrac{d}{dt}(xy+x)= \dfrac{d}{dt}(12)$ .
Use the chain rule:
$y\dfrac{dx}{dt}+x \dfrac{dy}{dt}+ \dfrac{dx}{dt}=0$ ,
Since x=2, y=5, <span>dx/dt = -3, then
</span>
$5\cdot (-3)+2\cdot \dfrac{dy}{dt}+(-3)=0, \\ 2\cdot \dfrac{dy}{dt}=18, \\ \dfrac{dy}{dt}=9$ .

Mathematics what is the distance between A (-6 -3) and b (-14 -18)

eduard

Answer:

The answer is

<h2>17 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x_1 - x_2})^{2} + ({y_1 - y_2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A (-6 -3) and b (-14 -18)

The distance between them is

$|AB| = \sqrt{ ({ - 6 + 14})^{2} + ({ - 3 + 18})^{2} } \\ = \sqrt{ {8}^{2} + {15}^{2} } \\ = \sqrt{64 + 225} \\ = \sqrt{289} \\ = 17 \: \: \: \: \: \:$

We have the final answer as

<h3>17 units</h3>

Hope this helps you
