and


<em />
<em> ---- Euler's constant</em>
So, we have:

Answer:
$168
Step-by-step explanation:
The formula we'll use for this is the simple interest formula, or:
I=Prt
Where:
P is the principal amount, $2000.00.
r is the interest rate, 4.2% per year, or in decimal form, 4.2/100=0.042.
t is the time involved, 2....year(s) time periods.
So, t is 2....year time periods.
To find the simple interest, we multiply 2000 × 0.042 × 2 to get that:
The interest is: $168.00
There are two triangles, a big triangle and a small triangle that is inside the big triangle. Because the base of the triangles are parallel to each other( indicated by the arrow), and the small triangle is perfectly inside the bigger triangle, the sides of the triangles are proportional.
It is know that the base of the small triangle is 3.5, and the hypotenuse of the small triangle is 7cm. it is also known that the the hypotenuse of the big triangle is (7+8)=15 and the base of the big triangle is unknown.
Since the triangles are proportional,
to find the base of the big triangle
base(big)/hypotenuse(big)=base(small)/hypotenuse(small)
Plug in the numbers
x/15=3.5/7
x/15=1/2
x=15/2
x=7.5
The length of the base of the big triangle is 7.5cm
First you grapgh 0,-3 then you follow the slope of going 4 up 5 to the right and contine up also on e-where it is 0,-3 you go down 4 and 5 to the left and contine that to make a straught line.
1_1/3 = 4/3
-3_1/4 = -13/4
(4/3) - (-13/4)
(4/3) + (13/4)
We can see that (4/3) + (13/4) leads to a positive answer.
