"Annual" means "year" while "semiannual" means "half a year". If the interest is compounded semiannually, then the interest is compounded twice a year (every half year or every 6 months).
So the final answer is choice B) 2
A fraction is bigger or smaller depending on the numerator and denominator.
For example, 1/2 is larger than 1/4 because a half is larger than a quarter. This means that the larger the number underneath, the smaller the number.
But, this can change if the numerator (the number on top) is different than one.
For example, 3/4 is greater than 1/2 because three quarters is more than a half. (two quarters is equal to a half)
Answer:
Width: 4
Length: 9
Step-by-step explanation:
P = 2( l + w)
26 = 2(2x + 1 + x)
26 = 2(3x + 1)
26 = 6x + 2
6x = 24
x = 4
l = 2x + 1
2(4) + 1 = 9
The area of the rectangle is changing at
0.75 sq.cm/min
Let
x
and
y
be the base and height of the rectangle.
x

cm is constant :. dx/dt=0#. Area of the rectangle
is
