Answer:
Quadratic equation follows form: ax^2 + bx + c = 0
a = 8
b = - 6
c = 13
Answer:
year 2139
Step-by-step explanation:
The population will double when the factor e^(.005t) is 2.
e^(.005t) = 2
.005t = ln(2)
t = ln(2)/0.005 = 138.6
The population will be double its size at t=0 when t=138.6. That is the population will be about 5.2 million in the year 2139.
Answer:
Step-by-step explanation:
Given
Required
The area of the garden
First, we calculate the length of the other side using:
This gives:
Divide both sides by 2
Make Side 2 the subject
So, the area of the garden is:
Expand
<span>16 + 306 = 1400x
322 = 1400x
x = 322/1400
</span><span>x = 0.23 = 23% (That is the concentration of the mixture)</span><span>Equation:
sugar + sugar = sugar
0.02*8 + 0.51*6 = x(8+6)
Multiply thru by 100 to get:
-----
2*8 + 51*6 = 1400x
