What is an equation of the line through (0,-3) with slope 2\5
baherus [9]
M=2/5  , (0,3)
use y= mx+c ,   find c first.
-3 = (2/5) 0 + c
c = -3
Thus the equation will be y=(2/5)x - 3.
or in some case,
(y1-y)=m(x1-x)
(-3-y)=(2/5)(0-x)

Can someone help me with this in a scientific notation
Leviafan [203]

Answer:

3.762 x 10^-7

Step-by-step explanation:

Alright this has the same exact concept as other scientific notation problems.

First, multiply your first numbers: 4.18 x 9 = 37.62

Next, we add our powers together -4 +-4 = -8 (can also be read as -4 - 4 = -8)

We now have 37.62 x 10^-8

Wait! This isn't in scientific notation.

Taking a closer look at this we see 37.62 x 10^-8 can be adjusted by moving the decimal over to the left. Scientific notation must be in simplest form with only one number on the left of the decimal. This gives up 3.762.

Now we need to adjust our notation. Since we moved the decimal over one we are adding one more power to our problem.

Our current power of -8 is now adding a power due to moving the decimal place over one unit to the left. This is equivalent to saying -8 + 1 which equals -7. Now that we fixed our powers, we can put our equation back together for our final answer

3.762 x 10^-7

soldier1979 [14.2K]

Answer:

15 ft

Step-by-step explanation:

Pythagoras formula for a triangle with a 90 degree angle :

a^2 + b^2 = c^2

c is the side opposite of the 90 degree angle. exactly or situation here.

=> 9^2 + 12^2 = x^2

=> 81 + 144 = x^2 = 225

=> x = sqrt(225) = 15
