if those r coordinates you can use the Pythagorean the to find the distance
plot the point and create a right triangle with the origin
could up the spaces and depending on the number, subtract the side from the hypotenuse or add the sides to find the hypotenuse
then square root both sides
COMPOUNDED
not simple interest,
compound interest is neat since you earn interest on the interest you earned
ok so what you use is F=Pe^(rt)
F=future or ending amount
P=present amount
e=base of the natural log (some digits are 2.71828182845)
r=rate in decimal
t=time in years
presen amount is 400
rate is 9% or 0.09
time is 3 years
F=400e^(0.09*3)
F=400e^(0.27)
F=523.986
round
F=523.99
Answer:
x = 11
Step-by-step explanation:
6x - 21 = 3x + 12
6x - 3x = 21 + 12
3x = 33
x = 33/3
x = 11
The rule for rounding is that if the fraction is less than 1/2, we round down; and if the fraction is more than 1/2, we round up.
Because 5/6 is a greater fraction than 1/2, we must round the existing whole number (8), up.
8 5/6 rounded to the nearest whole number is 9.
Angle 4: 98
Angle 3: 82
Angle 2: 98
This is true because 180-82 =98 meaning angle 2 and 4 are 98 leaving angle 3 to be 82
Hope this helps
