Answer:
a) 13913
b) 4913.82
Step-by-step explanation:
The compound interest formula is given by:
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
In this question:
Investment of 9000, so 
Interest rate of 8%, so 
Compounded quarterly, so 
5 years and 6 months, that is, 5 years and half, so 
(a) How much would the value of her savings at the end of the term?
(b) How much is the interest earned by your savings?
The amount subtracted by the principal. So
13913.82 - 9000 = 4913.82
Answer: ○|￣|_ =3
the answer would be 2, because the 30 is increased from the 3 by times 10 so it would be the same for the 20, 20/10=2
Step-by-step explanation: mr clean
2/3h - 1/3h + 11 = 8
1/3h = -3
h = -9
No. Terrell is not correct. Terrell is incorrect. The method he offers is
inappropriate, inapplicable, and lacks veracity, and as a mathematician,
Terrell himself is devoid of integrity. If his method is implemented, it
cannot accurately compute the capacity of Dominic's water jug in fluid
ounces. It will produce a number that is inaccurate, fallacious, mistaken,
erroneous, and incorrect. Moreover, the solution will be wrong.
If the units are carried through with the calculation ... as always they must ...
then it will immediately become clear that Terrell's method has produced a
solution with units of "square quarts per ounce", whereupon any witnesses
should justifiably become nauseous. Terrell's method should be disdained,
rejected, discarded and ignored.
==> 1.25 should not be "divided" by 32.
==> Instead, 1.25 should be<span> multiplied </span>by 32.
The modified method will produce a result with units of "fluid ounces" ...
the first indication to the assembled multitude that whatever the number
is, there is a reasonable chance that it could be a correct one.
The question is
A square and an equilateral triangle have equal perimeters. The area of the triangle is 2√3 sq<span>uare inches. What is the number of inches in the length of the diagonal of the square?
</span>
we know that
the area of an equilateral triangle is
applying the law of sines
A=(1/2)*b²*sin 60°-----> 2√3=(1/2)*b²*√3/2
(2√3)*(2/√3)=(1/2)*b²
4=(1/2)*b²
b²=8
b=√8 in
perimeter of the triangle=3*b-----> 3*√8 in
let
x----> the length side of the square
perimeter of the square=perimeter of the triangle
perimeter of the square=3*√8 in
and
perimeter of the square=4*x
4*x=3*√8
x=(3/4)*√8----> x=(3/2)*√2 in
find the diagonal of the square
applying the Pythagoras theorem
D²=x²+x²----> D²=2*x²----> D²=2*((3/2)*√2)²
D²=2*(9/4)*2
D²=9
D=3 in
the answer is
the number of inches in the length of the diagonal of the square is 3
