Ms. Cohen's garden had 50 weeds when she began spraying her garden with pesticide. Every day she sprayed pesticide there were half as many weeds as the day before.
(Let x = the number of days and y = number of weeds)
Answer:
c or 50(0.5)^x
Step-by-step explanation:
The exponential function for the number of pesticides will be y = [tex]50(0.5)^{x}[/tex]
What is an exponential function?An exponential function is a mathematical function of the following form: f(x) = a^x. where x is a variable, and a is a constant called the base of the function.

Answer:
So you have it right. 15 5/7 in
Step-by-step explanation:
C = πd
All you can do now is substitute what has been given
Diameter = 5
Pi = [tex]\frac{22}{7}[/tex]
C = [tex]\frac{22}{7}[/tex] * 5
Multiply from across
22 * 5 = 110 ( numerator)
7 * 1 = 7 (denominator)
110/7 (improper fraction) = 15.71428571428571 ( as a decimal) = 15 5/7 ( as a mixed number)
Ik its 15 5/7 because 1. the 15 wont change, and 2 5/7 = 0.7142857142857143, which is the same one as above
Hope this helped!

what does the a in y=a(1+r)x represent?
Answer:
The function is of the form y = a(1 − r)t, where 1 − r < 1, so it represents exponential decay. Use the decay factor 1 − r to find the rate of decay. Write an equation. Solve for r.
The "a" in the expression y = a (1+r)ˣ represents the initial amount.
What is the expression?An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.
Given, a exponential expression y = a (1+r)ˣ
The exponential growth can alternatively be calculated using the formula f(x) = a(1 + r)ˣ, where the function is denoted by the f(x) term. The initial value of your data is represented by the variable. The growth rate is represented by the r variable.
Therefore, the initial amount is been represented by "a" in the given expression.

Camryn ran for 13 minutes, walked for 17 minutes, ran for another 13 minutes, and then sat down and stretched in place for 17 minutes. Her total distance traveled is a function of time.
Which graph most accurately represents this scenario? (4 points)
A graph is shown with a starting point at the origin. The x-axis is labeled Time (in hours), and the y-axis is labeled Total distance (in miles.) The graph moves upward, then at 0.25 hours moves up at a slower pace until it reaches 0.5, where it moves up at a fast pace again before changing to a horizontal line from 0.75 to 1
A graph is shown with a starting point at 0 comma 1.2. The axis is labeled Time (in hours) and the y-axis is labeled Total distance (in miles). The graph is horizontal until x equals 0.25 hours, then moves downward to 0.5. From 0.5 to 0.75, the graph moves upward quickly, before continuing down to touch the x axis at x equals 1

Answer:
The first one is correct.
Step-by-step explanation:
The first one is correct, because Camryn went fast. And then she she went at a slower pace, and then she picked up speed again and starting running. FFianlly, the line would go horizontally, because her distance is not changing.

What is the solution of the system?
Answer:
(-2, 6)
Step-by-step explanation:
We can simply do this by plugging in all of the coordinates. (I did this in my head quickly, so I know what it is; I'm just going to plug in the correct answer.) The correct answer is (-2, 6), so we're just going to plug them into the simplest equation, which is probably y=-3x. So...
6=-3(-2)
6=6
This answer is correct. If you're unsure about the answer, you can always check in the other equation. So...
3(-2)+2(6)=6
-6+12=6
6=6
