The answer is not any of the letters. I got x=15/2 or x=7.5. You may have made an error in your question.
- Rewrite each of the following as an expression of x which does not involve any logs<span>.? Can someone show me ... Best Answer: To do it you have to know that 1000 = 10³ ; </span>100<span> = 10² ; .01 = 10^-2 </span>log 10<span>^3x = 3x 10^(2logx) = x²</span>
Answer:
$52
Step-by-step explanation:
Using the equation
y=mx+c
82=7x+c
122=11x+c
11x-7x=122-82
4x=40
x=10
To get c
82=7(10)+c
82-70=c
c=12
For 4 lessons
y=10(4)+12=52
Answer: 2/3 is the slope I think and for the same slope thing here is my answer:
We can use similarly of triangles in this case there will be a formation of 2 pairs equal ( angles formed by the y-axis on the parallel lines) angles between triangles formed as the y-axis lines are parallel. So,the slope is the same for both.
Answer: Approximately 25187 animals of this species will be left in 2025
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
y = b(1 - r)^x
Where
y represents the population of animals after x years.
x represents the number of years.
b represents the initial population of animals.
r represents rate of decay.
From the information given,
b = 200000
r = 4.5% = 4.5/100 = 0.045
x = 2025 - 1980 = 45 years
Therefore,
y = 200000(1 - 0.045)^45
y = 200000(0.955)^45
y = 25187
