Hi!

Solution:

1. You have to move the decimal point until you have a number that is between 1 and 10.

2. Then add a power of 10, which would tell you how many decimal places you moved.

_______________________________

In your case:

78,000,000 —> you would move the

decimal point 7 times to the left and

your new number will be 7.8 ( which is

between 1 and 10.


Since you moved 7 places to the left,

your power of 10 will be 10^7 or 10 to the

7th power.


Your Answer: 7.8 x 10^7

Hope this helps!

Answer:

7.8×10⁷

Step-by-step explanation:

You want to keep the coefficient (7.8) between 1 and 10 to achieve a normalized notation. Otherwise 78×10⁶ would also be an option.

Delvig [45]
Let
x ----------> the height of the whole poster
<span>y ----------> the </span>width<span> of the whole poster
</span>
We need to minimize the area A=x*y

we know that
(x-4)*(y-2)=722
(y-2)=722/(x-4)
(y)=[722/(x-4)]+2

so
A(x)=x*y--------->A(x)=x*{[722/(x-4)]+2}
Need to minimize this function over x > 4

find the derivative------> A1 (x)
A1(x)=2*[8x²-8x-1428]/[(x-4)²]

for A1(x)=0
8x²-8x-1428=0
using a graph tool
gives x=13.87 in

(y)=[722/(x-4)]+2

y=[2x+714]/[x-4]-----> y=[2*13.87+714]/[13.87-4]-----> y=75.15 in

the answer is
<span>the dimensions of the poster will be
</span>the height of the whole poster is 13.87 in
the width of the whole poster is 75.15 in
