Answer:
Step-by-step explanation:
We need to solve the following
that we can write
so the answer is 2
Answer:
y = 240000 x e^(0.078 x t)
Step-by-step explanation:
This is exponential growth, so the power at the exponential function will be positive ( negative is for exponential decay.) Since it is increasing by 7.8 percent exponentially we can write an exponential function relating y with t.
Step-by-step explanation:
x^3+x^2+4x+4=0
x³+x²+4x=-4
x(x²+x+4)=-4
either
x=-4
or
x²+x+4=-4
x²+x+4+4=0
x²+x+8=0
comparing with ax² +bx+c
a=1
b=1
c=8
x={-1±√{1²-4×1×8}}/2×1
x={-1±√{-31}}/2
Answer:
Step-by-step explanation:
Remember that
we have
In this problem
b represent the 100%
so
using proportion
Find out what percent of b represent a
Let
x -----> the percentage of b
Convert to mixed number
Answer:
Multiply the area of the base by the height and divide by 3.
Step-by-step explanation:
V = (1/3)Bh
where B = area of the base, and
h = height
Answer: Multiply the area of the base by the height and divide by 3.
