Answer:
(4,5)
Step-by-step explanation:
In this problem it
states that one tenth or only 10% is Canada’s population to the United States.
Hence with the steps we
can identify the population of the United States.
<span><span>1.
</span>10 %
= 32 million or 0.1 = 32 million</span>
<span><span>2.
</span>Then 32
million / 0.1 = 320, 000, 000 million</span>
Therefore there are 320,
000, 000 million living in the United States
Adding one zero. Why the zeroes? It is
the result because of the power of 10 in a hundred percent population coming
from the Canada’s population. Take note that 100% = 320, 000, 000 million of
the USA while 10% of it is Canada so we divide it by 0.1 which is 32, 000, 000
(the power of ten)
| u | = √(2² + (-1²)) = √5
| v | = √ ( 1² + (-8)² = √65
cos (u,v) = ( u * v ) / (| u | * | v |) =
(2 * 1 + ( -1 ) * ( - 8 )) / √5 √ 65 = (2 + 8) / √5 √65 = 10 / (√5 √ 65 )
The length of a larger diagonal:
d 1² = | u |² + 2 |u| |v| + | v |² = 5 + (2 √5 √65 * 10 / √5 √65 )+65
d 1² = 70 + 20 = 90
d 1 = √ 90 = 3√10
d 2² = 70 - 20 = 50
d 2 = √50 = 5√2
Answer:
The lengths of the diagonals are: 3√10 and 5√2 .
10.7=11 is the answer to 23.5 divide by 2.5
