Mr.Samuel planted 40 pepper plants when he began his garden in 2005. Each year the number of pepper plants doubled. The number of plants,f(x),after x years is modeled with an exponential function
Answer:
[tex]f(x)=40*2^x[/tex]
Step-by-step explanation:
Mr Samuel Planted 40 pepper plants in 2005.
Therefore:
f(0)=40
Each year the number of pepper plants doubled.
In 2006, f(1)=40*2
In 2007, f(2)=40*2*2[tex]=40*2^2[/tex]
In 2008, f(3)=40*2*2*2[tex]=40*2^3[/tex]
If we continue in like manner. The number of pepper plants after x years will be given by the exponential function:
[tex]f(x)=40*2^x[/tex]
where 40 is the initial number and 2 is the growth factor.

To determine the weight for each animal and their total combined weight, you would need to know the weight of each individual animal. Let's say we have three animals: a lion weighing 200 pounds, a zebra weighing 300 pounds, and a giraffe weighing 500 pounds. To find their total combined weight, you simply add up their weights: 200 + 300 + 500 = 1000 pounds.

Jalen is in a 24 hour dance-a thin as part of a fundraiser. He raised $50 in the first hour of competition. Then another 60 in the second hour. Then another $72 dollars in the third hour. If this pattern continues what is the total amount of money he will earn if he stays in the entire competition
Answer: $786
Step-by-step explanation:
first hour = $50
Second hour = $60
Third hour = $72
Total amount after 24 hours :
4th hour = 72 + 1 4 = 86
5th = 86 + 16 = 102
6th = 102 + 18 = 120
7 = 120 + 20 = 140
8 = 140 + 22 = 162
9 = 162 + 24 = 186
10 = 186 + 26 = 212
11 = 212 + 28 = 240
12 = 240 + 30 = 270
13 = 270 + 32 = 302
14 = 302 + 34 = 336
15 = 336 + 36 = 372
16 = 372 + 38 = 410
17 = 410 + 40 = 450
18 = 450 + 42 = 492
19 = 492 + 44 = 536
20 = 536 + 46 = 582
21 = 582 + 48 = 630
22 = 630 + 50 = 680
23 = 680 + 52 = 732
24 = 732 + 54 = 786
An adult takes 800 mg of ibuprofen. Each hour, the amount of ibuprofen in the person's
system decreases by about 32%. How much ibuprofen is left after 5 hours?
Answer:
116.31468544 mg ibuprofen left
Step-by-step explanation:
Since there are 800 mg at the beginning and the system decreases by about 32% of the ibuprofen
After 1 hour
→ 800 - (800x32/100) = 800 - 256 = 544 mg ibuprofen left
After 2 hours
→ 544 - (544x32/100) = 544 - 174.08 = 369.92 mg ibuprofen left
After 3 hours
→ 369.92 - (369.92x32/100) = 369.92 - 118.3744 = 251.5456 mg ibuprofen left
After 4 hours
→ 251.5456 - (251.5456x32/100) = 251.5456 - 80.494592 = 171.051008 mg ibuprofen left
After 5 hours
→ 171.051008 - (171.051008x32/100) = 171.051008 - 54.73632256 = 116.31468544 mg ibuprofen left
To find the amount of ibuprofen left after 5 hours, the initial 800 mg is multiplied by 0.68 raised to the 5th power, resulting in approximately 115.28 mg remaining.
To calculate the amount of ibuprofen left after 5 hours, we can use the exponential decay formula. Since the amount decreases by 32% each hour, we can represent this as a decay rate of 68% (100% - 32%) remaining each hour. Therefore, the amount of ibuprofen after one hour is 68% of the initial amount, and we can represent this as a multiplication by 0.68 for each passing hour.
The formula to find the amount of ibuprofen left after 5 hours is:
Final amount = initial amount × (0.68)⁵
Using the initial amount of 800 mg and raising 0.68 to the 5th power:
Final amount = 800 mg × 0.68⁵
Final amount = 800 mg × 0.1441
Final amount ≈ 115.28 mg
So, approximately 115.28 mg of ibuprofen is left in the adult's system after 5 hours.
The electrical charge on a metal plate is given
by the function below, where t is the time in
seconds. What is the charge after 10 seconds?
C (t) = 12e +15
Answer:
after 10 seconds the charge is 1.624
Step-by-step explanation:
I think your question missed key information, allow me to add in and hope it will fit the orginal one.
The electrical charge on a metal plate is given by the function below, where t is the time in seconds. What is the charge after 10 seconds?
C (t) = 12[tex]e^{\frac{-t}{5} }[/tex]
My answer:
Given the information:
C (t) = 12[tex]e^{\frac{-t}{5} }[/tex]
when t =10 we have:
C (10) = 12[tex]e^{\frac{-10}{5} }[/tex]
<=> C (10) = 12[tex]e^{-2}[/tex]
<=> C (10) = 12[tex]\frac{1}{e^{2} }[/tex]
<=> C (10) = 12 * 0.1353
<=> C (10) = 1.624
Hence, after 10 seconds the charge is 1.624
What is the product of 5.61 and 0.15
Answer:
0.8415 :)
Step-by-step explanation:
To find the product of 5.61 and 0.15, multiply the two numbers to get 2805 and then place the decimal to account for a total of four decimal places in both numbers, resulting in a product of 0.8415.
Explanation:The product of 5.61 and 0.15 is calculated by simply multiplying the two numbers together. To do this, you can line up the numbers as you would in any multiplication problem, making sure to pay attention to the decimal places:
5.61Since there are two decimal places in each number we are multiplying (two in 5.61 and two in 0.15), we need to have a total of four decimal places in the answer. Taking the raw multiplication result of 2805 and inserting the decimal correctly, we get the final answer:
0.8415Therefore, the product of 5.61 and 0.15 is 0.8415.
A cone and a cylinder have the same base and height, as shown below.
The volume of the cylinder is 84 sin? What can be concluded about the volume of the cone? Check all that apply
The volume of the cone is
the volume of the cylinder.
The volume of the cylinder is 2 times the volume of the cone.
The volume of the cone is less than the volume of the cylinder
Answer:
The volume of the cone is less than the volume of the cylinder .
Cone volume is 1/3 the volume of cylinder volume
Step-by-step explanation:
We can see from the volume formulas:
for cone volume V = (1/3)*(pi)*(r^2)*h
for cylinder volume C = (pi)*(r^2)*h
for equal base and height, C = 3*V
The volume of the cone is less than the volume of the cylinder .
Cone volume is 1/3 the volume of cylinder volume
The correct answers are:
A) The volume of the cone is 1/3 the volume of the cylinder.
C) The volume of the cone is less than the volume of the cylinder.
D) The expression 84(pi)/3 finds the volume of the cone.

2ft, 3ft, 4ft
2ft, 3ft, 5ft
2ft, 4ft, 5ft

Using the Triangle Inequality Theorem, we can conclude that the pieces of wood measuring 2ft, 3ft, 4ft, and 3ft, 4ft, 5ft can be used to build a triangle-shaped garden.
To determine which pieces of wood can be used to build a triangle-shaped garden, we need to apply the Triangle Inequality Theorem. This theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. We will check each set of wood pieces to see if they fit this criterion.
2ft, 3ft, 4ft: Do these lengths satisfy the Triangle Inequality Theorem? Yes, because 2 + 3 > 4, 2 + 4 > 3, and 3 + 4 > 2.2ft, 3ft, 5ft: Do these lengths satisfy the theorem? No, because 2 + 3 is not greater than 5. Therefore, these cannot form a triangle.2ft, 4ft, 5ft: Do these lengths satisfy the theorem? No, because 2 + 4 is not greater than 5.

helppppppppppppppppppppppppppppp
Answer:
942 cm³.
Step-by-step explanation:
To find the volume of the cone, we will need to use the formula: [tex]\frac{1}{3}[/tex]bh.
To find the base, we simply need to find the area of the circle. This is done by using: [tex]\pi r[/tex]².
From this, we get a base area of ≈314 cm².
Now, to find the volume of the cone, we, multiply by the height giving us:
314×9= 2826.
Finally, the last step is to multiply this by [tex]\frac{1}{3}[/tex], resulting in:
2826×[tex]\frac{1}{3}[/tex]= 942.
Therefore, 942 cm³ is the correct answer.

Equation 1: 5x + 3y = 19
Equation II: 2x - 4y = -8
In solving the system of equations, which operations will allow the elimination of the variable x in the next step?
Answer:
C
Step-by-step explanation:
If you multiply the top equation by 2 and the bottom equation by -5, then there will be a 10x in the first equation and a -10x in the second, which you can cancel out in the next step. Therefore, the correct answer choice is C. Hope this helps!
To eliminate x, we need to make the coefficient of x the same in both equations. We achieve this by multiplying Equation I and Equation II by certain numbers. Subtraction of the modified equations then eliminates x, leaving one equation with y.
Explanation:To eliminate the variable x in the system of equations, we need to multiply each equation by a number that would make the coefficients of x in both equations equal, such that they cancel each other out when we add or subtract the equations.
For the given equations: Equation I: 5x + 3y = 19 and Equation II: 2x - 4y = -8, we can multiply Equation I by 2 and Equation II by 5.
This will result in:
Equation I: 10x + 6y = 38 and Equation II: 10x - 20y = -40
By subtracting Equation II from Equation I, we are able to eliminate the x variable, resulting in the equation 26y = 78.

12.6+4m=9.6+8m12.6+4m=9.6+8m
Answer:
m = 3/4
Step-by-step explanation:
12.6+4m=9.6+8m
Isolate the variable, m. Note the equal sign, what you do to one side, you do to the other.
Subtract 4m and 9.6 from both sides:
12.6 (-9.6) + 4m (-4m) = 9.6 (-9.6) + 8m (-4m)
12.6 - 9.6 = 8m - 4m
Simplify:
12.6 - 9.6 = 8m - 4m
3 = 4m
Isolate the variable, m. Divide 4 from both sides:
4m = 3
(4m)/4 = (3)/4
m = 3/4
3/4 is your answer for m.
~
Answer:
3/4 =m
Step-by-step explanation:
12.6+4m=9.6+8m
Subtract 4m from each side
12.6+4m-4m =9.6+8m-4m
12.6 = 9.6 +4m
Subtract 9.6 from each side
12.6 - 9.6 = 9.6 - 9.6 +4m
3 = 4m
Divide each side by 4
3/4 = 4m/4
3/4 =m
