Square root of 784 by prime factorization
Digiron [165]

Answer:

Step-by-step explanation:

Hello,

we can divide 784 by 2 and then again by 2 etc until we find all the terms as below

784 = 2*2*2*2*7*7 that we can write

784=2^47^2

Then

\sqrt{784}=\sqrt{2^47^2}=\sqrt{2^4}*\sqrt{7^2}=2^2*7=4*7=28

hope this helps

What is the value of x
goblinko [34]

Answer:

52/3

Step-by-step explanation:

Use basic Thales therom,

\frac{3x}{4x}=\frac{3x+7}{5x-8}\\\\\frac{3}{4}=\frac{3x+7}{5x-8}\\

Cross multiply,

3*(5x-8)=4*(3x+7)

3*5x - 3*8 = 4*3x + 4*7

15x - 24 = 12x +28

Add 24 to both sides

15x = 12x + 28 + 24

15x = 12x + 52

Subtract 12x from both sides

15x-12x =52

3x = 52

Divide both sides by 3

x = 52/3

Newton's Law of cooling is
T(t)=T_{a}+(T_{0}-T_{a})e^{-0.1947t}
where
T(t) = temperature of the body after t hours, 80 °F
T_{a} =  ambient temperature, 65 °F
T_{0} = normal body temperature, assumed to be 98.6 °F

The elapsed time since death is obtained from
65+(98.6-65)e^{-0.1947t|} = 80
33.6e^{-0.1957t}=15
-0.1947t=ln \frac{15}{33.6}
t= \frac{ln(15/33.6)}{-0.1947} =4.142

4.142 hours before 2 am is 9:52 pm (the previous day) approximately.

Answer:  9:52 pm the previous day.
