A plant will become invasive when the number of plants reaches 10,000. Model the situation with an exponential growth function. How many years will it take for the plant to become invasive? Explain how you found the situation.
Answers
It would take 43 years for the plant specie to become invasive.
How many years would it take the plants to become invasive?We know that the increase of the plant is following the exponential function and this can be seen from the question that we have here. We now have to create a model that we can use to solve the question.
Using
Pt = Poe^rt
Pt = population at time t
Po = initial population
r = population growth rate
t = time taken
Then;
10000 =500e^0.07t
10000/500 = e^0.07t
20 = e^0.07t
ln20 = 0.07t
t = ln20/0.07
t = 43 years

Answers
Answer:
The distributive law of multiplication states that when a number is multiplied with the sum is equal to the number multiplied by each addend with the number and then sum of the both products.
by example a*(b+c)=(a*b) + (a*c)
Here the expression A is (5/6)*250
the expression B is ( 1/3 × 250 ) + ( 1/2 × 250 )
expression B is ( 1/3 × 250 ) + ( 1/2 × 250 )
=250*(1/3+1/2) applying distributive law of the multiplication
=250*((2+3)/6)
=250*(5/6)
=(5/6)*250
Therefore the expression A is equal to the expression B.

A runner completed a 26.2-mile marathon in 210 minutes.
- Estimate the unit rate, in miles per minute. Round your answer to the nearest hundredth.
- Estimate the unit rate, in minutes per mile. Round your answer to the nearest tenth.
- Another runner says, "I averaged 10-minute miles in the marathon." Is this runner talking about the unit rate described in part (a) or in part (b)?
- Explain your reasoning.
Answers
Answer:
0.123 miles per min
8 mins per mile
The runner is talking about part (b)
Part a) is miles per minute and the runner said they did 10 minutes every mile same thing as minutes per mile or part b
Step-by-step explanation:
Since your doing per minute you do you do the amount of miles over the amount of minutes so you can see how many miles the runner went in each minute
And when doing per mile its the same idea you just minutes over miles now so you get for every mile the number of minutes.
One boxcar of a model train measures 6 inches in length. The actual length of a boxcar is 606 inches (50.5 ft). What is the scale of the model?
Answers
To find the scale of the model train boxcar, we need to determine the ratio of the actual size of the boxcar to the size of the model. We can do this by dividing the actual size of the boxcar by the size of the model:
scale = actual size / model size
Plugging in the values from the problem, we get:
scale = 606 inches / 6 inches
Simplifying this expression gives us:
scale = 101
So, the scale of the model train boxcar is 101. This means that for every 1 inch of the model, there are 101 inches in the actual size.

Answer:
There are 16 nickels and 15 dimes.
Step-by-step explanation:
let x = number of dimes
let y = number of nickels
x + y = 31
.1x + .05y = 2.30
Solve x + y = 31 for x
x = 31 - y
multiple the second equation by 100 to eliminate the decimals.
10x + 5y = 230 Substitute 31 - y for x
10(31-y) + 5y = 230 Distribute the 10
310 -10y + 5y = 230 Combine like terms
310 -5y = 230 Subtract 310 from both sides
-5y = -80 Divide both sides by -5
y = 16
There are 16 nickels.
Plug in 16 for y to solve for x
x + y = 31
x + 16 = 31 Subtract 16 from both sides
x = 15
There are 15 times.
Check:
10x + 5y = 230
10(15) + 5(16) = 230
150 + 80 = 230
230 = 230

When x = 0, y = 1,
lhs of (1) = 0 - 5 = - 5
lhs of (2) = 1 - 0 = 1
