The current, I, varies inversely to the resistance, R. If the current is 250 milliamperes when the resistance is 5 ohms, find th

Arturiano [62]

Answer:

c) 62.5 mA
c) 9 seconds

Step-by-step explanation:

1. resistance is multiplied by 20/5 = 4, so current is multiplied by 1/4.

(1/4)(250 mA) = 62.5 mA . . . . matches choice C

2. distance is multiplied by 144/16 = 9, so time is multiplied by √9 = 3. The time it takes to fall 9 times as far is ...

3 × 3 seconds = 9 seconds . . . . matches choice C

Simora [160]

Answer:

20 + 1 + 0.9 + 0.07

Step-by-step explanation:

Given the number 21.97 ;

To wite in expanded form:

Tens ___ Unit ____ tenth ____ hundredth

2_______ 1 _______ 9_________ 7

2 = 20

1 = 1

9 = 0.9

7 = 0.07

Hence,

20 + 1 + 0.9 + 0.07

klasskru [66]

Given:

Point B has coordinates (4,1).

The x-coordinate of point A is -4.

The distance between point A and point B is 10 units.

To find:

The possible coordinates of point A.

Solution:

Let the y-coordinate of point A be y. Then the two points are A(-4,y) and B(4,1).

Distance formula:

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

The distance between point A and point B is 10 units.

$\sqrt{(4-(-4))^2+(1-y)^2}=10$

Taking square on both sides, we get

$(8)^2+(1-y)^2=100$

$(1-y)^2=100-64$

$(1-y)^2=36$

Taking square root on both sides, we get

$(1-y)=\pm \sqrt{36}$

$-y=\pm 6-1$

$y=1\mp 6$

$y=1-6$ and $y=1+6$

$y=-5$ and $y=7$

Therefore, the possible coordinates of point A are either (-4,-5) or (-4,7).
