Answer:
y=6/5x-8
Step-by-step explanation:
y=mx+b
-2=6/5(5)+b
-2=6+b
b=-8
Answer:
It will take the 20 years for the population to quadruple.
Step-by-step explanation:
Exponential population growth:
An exponential model for population growth has the following model:
In which P(0) is the initial population and r is the growth rate, as a decimal.
It grows with a doubling time of 10 years.
This means that 
. We use this to find r. So
![\sqrt[10]{(1+r)^10} = \sqrt[10]{2}](https://tex.z-dn.net/?f=%5Csqrt%5B10%5D%7B%281%2Br%29%5E10%7D%20%3D%20%5Csqrt%5B10%5D%7B2%7D)
So
Determine how long it will take for the population to quadruple.
This is t for which P(t) = 4P(0). So
It will take the 20 years for the population to quadruple.
Answer:
You find the surface area with:
10*2+10*2+4*2+4*2+2*2+2*2+4*7+4*7+4*4+4*4 or in short 152 in^2.
We are given statement 3.59 > 3.5__1 >3.572.
We have a blank space in between 5 and 1 in the middle number given.
Given statement ccan be read as :
3.59 is greater than 3.5__1 is greater than 3.572.
So, we need to check a number that is less than 3.59 but less than 3.572.
The hundredth place of 3.59 number is 9 and
hundredth place of 3.572 number is 7.
So, we need to find a number between 7 and 9.
8 is the number in between 7 and 9.
So, the known digit can be replaced by 8 to make the statement true.
And final statement is 3.59 > 3.581 >3.572.
Answer:
-4 5/12
Step-by-step explanation:
-23/3 + (-11/2) + 35/4
<em>Find a common denominator (12).</em>
-92/12 + (-66/12) + 105/12
<em>Reform the equation to have this as a single fraction.</em>
(-92 + (-66) + 105)/12
<em>Subtract 66 from -92 to get -158.</em>
(-158 + 105)/12
<em>Add 105 to -158 to get -53.</em>
-53/12
<em>Convert into a mixed number by dividing by 12.</em>
-4 5/12 (Choice A) is your answer.
