To multiply 9x475 using expanded form and the distributive property, you will break 475 into three numbers, multiply each of them by 9, and add the products together:

475 = 400 + 70 + 5

400x9 = 3600
70x9 = 630
5x9 = 45

3600 + 630 + 45 = 4,275

BRAINLIEST!!!!<br><br><br> Identify the equation of the translated graph in general form
RUDIKE [14]

Answer:

Hyperbola:

x^2-y^2-8x+6y-1=0

Step-by-step explanation:

the given hyperbola has equation:

x^2-y^2=8

This is an equation of a hyperbola centered at the origin.

This hyperbola is translated so its center is now at T(4,3)

(x-4)^2-(y-3)^2=8

We expand to get:

x^2-8x+16-(y^2-6y+9)=8

x^2-8x+16-y^2+6y-9=8

x^2-8x-y^2+6y+7=8

x^2-8x-y^2+6y+7-8=0

x^2-y^2-8x+6y-1=0

If a radioactive isotope has a half-life of 6 hours and 12 milligrams is initially present, how much will
Serhud [2]

Answer:0.75 milligrams will  be present in 24 hours

Step-by-step explanation:

Step 1

The formula for radioactive decay can be written as

N(t)=No (1/2)^(t/t 1/2)

where

No= The amount of the radioactive substance at time=0=milligrams

t 1/2= the half-life= 6 hours

t=24 hours

N(t) = the amount at time t

Step 2--- Solving

N(t)=No (1/2)^(t/t 1/2)

=N(t)=12 x ( 1/2) ^ (24/6)

= 12 x (1/2) ^4

= 12 x 0.0625

= 0.75 milligrams
