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.
Given that, 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
According to question,
y = [tex]50(0.5)^{x}[/tex]
Hence, The exponential function for the number of pesticides will be y = [tex]50(0.5)^{x}[/tex]

Answer:
X is equal to 2. hope it will help you
Answer:
x=2
Step-by-step explanation:
4x+9= 17
4x=17-9 ( because +9 has gone to next side so it's sign is changed -9)
4x=8
x=8/4(4 wasin (×) so sign changed in(÷) )

Solve for the value of a.
Answer:
a=11
Step-by-step explanation:
So, the line that (9a+6) and 75 are sharing is straight, meaning that it is 180 degrees. Also, (9a+6) and 75 are sharing the line. Even though we don't know there exact measurements, when know that by adding them together we will get 180 degrees.
1. (9a+6) + 75 = 180
2. 9a + 81 = 180
3. 9a = 99
4. a = 11

Which equation represents a linear function?
A) x = y2
B) y – 2 = x2 + 5x
C) y = x3 + 1
D) 5x + 6y = 12
Answer:
D) 5x + 6y = 12
Step-by-step explanation:
x = y^2 is Not Linear (Find the degree of the equation to determine if linear.)
y - 2 = x^(2) + 5x is Not Linear (Find the degree of the equation to determine if linear.)
y = x^(3) + 1 is Not Linear (A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 3.
5x + 6y = 12 is Linear (Find the degree of the equation to determine if linear.)

what is the distance rounded to the nearest tenth between the points (2 -2) and (6 3)
Answer:
The distance between the points is approximately 6.4
Step-by-step explanation:
The given coordinates of the points are;
(2, -2), and (6, 3)
The distance between two points, 'A', and 'B', on the coordinate plane given their coordinates, (x₁, y₁), and (x₂, y₂) can be found using following formula;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Substituting the known 'x', and 'y', values for the coordinates of the points, we have;
[tex]l_{(2, \, -2), \ (6, \, 3) } = \sqrt{\left (3-(-2) \right )^{2}+\left (6-2 \right )^{2}} = \sqrt{5^2 + 4^2} = \sqrt{41}[/tex]
Therefore, the distance between the points, (2, -2), and (6, 3) = √(41) ≈ 6.4.

Step-by-step explanation:
When rotating a point 270 degrees counterclockwise about the origin our point A(x, y) becomes A'(y,-x). This means, we switch x and y and make x negative,
hence A(2,1) so after 270 degree counter clockwise rotation the A become,
A(1, -2)

Eiman borrowed $8000 at a rate of 14.5%, compounded semiannually. Assuming she makes no payments,
how much will she owe after 6 years?
Do not round any intermediate computations, and round your answer to the nearest cent.?
Answer:
1,717,351cents
Step-by-step explanation:
Using the compound interest formula
A = P(1+r/n)^nt
P = 8000
r = 14.5% = 0.145
n = 6/12 = 1/2 (semi annually)
t = 6years
Substitute
A = 8000(1+ 0.145/0.5)*(0.5)(6)
A = 8000(1+0.29)^3
A = 8000(1.9)^3
A = 8000(2.146689
A = 17,173.512
Hence the amount owned to the nearest cent is 1,717,351cents
