Q. One number is 2 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 200, find the number
Answer:First number = x
One number = 2x
Third number = 100 + x
x + 2x + 100 + x = 200
Collect like terms
4x + 100 = 200
4x = 100
x = 25
First number = 25
One number = 50
Third number =125
Total= 200
Hope this helps.
Y = 300e^(-Bt)
plug in y = 75 and t = 2
75 = 300e^(-2B)
75/300 = e^(-2B)
ln(75/300) = -2B
B = -ln(75/300) / 2
so B = approx 0.693300 = A(e^0) = A

So you will want this to be simplified.
expanding brackets is a great way of doing this
one you have expanded all brackets u get the answer above

Answer:
Step-by-step explanation:
As the base is a square so the length is a, width is a and the height is h.
According to the question,
a + a + h = 96
h = 96 - 2a .... (1)
Volume of the box, V = length x width x height
V = a x a x h
V = a² (96 - 2a) from equation (1)
V = 96a² - 2a³
Differentiate both sides
Now put it equal to zero.
192 a - 6a² = 0
a = 32 in
h = 96 - 2 x 32
h = 32 in
Thus, the length and the width os teh base is 32 in and the height is 32 in.
