Answer:
Without them, there would have been no United States of America.
The Founding Fathers, a group of predominantly wealthy plantation owners and businessmen, united 13 disparate colonies.
They fought for independence from Britain and penned a series of influential governing documents that steer the country to this day.
All the Founding Fathers, including the first four U.S. presidents, at one point considered themselves British subjects.
But they revolted against the restrictive rule of King George III outlining their grievances in the Declaration of Independence, a powerful call for freedom and equality.
They won a stunning military victory over what was then the world’s preeminent superpower.
Answer:
1) The lateral area is LA=95 cm²
2) The surface area is SA=275 cm²
The answer is the option D) 95 cm² ; 275 cm²
Step-by-step explanation:
we know that
The surface area of the box (rectangular prism) is equal to
SA=2B+LA
where
B is the area of the base
LA is the lateral area of the box
<em>Find the lateral area</em>
LA=PH
where
P is the perimeter of the base
H is the height of the box
substitute
LA=2[15+6](2.26)=94.92 cm²
Round to the nearest whole number
LA=95 cm²
<em>Find the area of the base B</em>
B=(15)(6)=90 cm²
Find the surface area of the box
SA=2B+LA
substitute the values
SA=2(90)+95=275 cm²
Answer:
a) r=-0.00012097
b)
c) 13,304.65 years
Step-by-step explanation:
a)
Q(t) satisfies the differential equation Q'(t) = rQ(t), hence
Integrating on both sides
where C is a constant. Taking the exponential on both sides
In this case, is the initial value Q(0), the amount of the initial value of carbon-14 and we have
As we know that the half-life of carbon-14 is approximately 5,730 years we have
Taking logarithm on both sides
and
b)
c)
We want to find a value of t for which
Q(t) = 20% of =
and
