the number of squirrels in a park at the end of the month
Using the given recursive function, we have that:
a) There will be 132 squirrels in the park at the end of August.
b) As time goes by, the number of squirrels in the park will increase.
What is the recursive function for this problem?
The recursive function for this problem models the number of squirrels in the park at the end of month n+1, considering the amount present at the end of month n, as follows:
[tex]S_{n+1} = 1.6S_n - 30[/tex]
For this problem, we have that at the amount at the end of May is of 70, hence:
[tex]S_{5} = 70[/tex]
Hence, we find the amounts at the end of June, July and August, as follows:
[tex]S_6 = 1.6(70) - 30 = 82[/tex].[tex]S_7 = 1.6(82) - 30 = 101[/tex].[tex]S_8 = 1.6(101) - 30 = 132[/tex].Hence:
a) There will be 132 squirrels in the park at the end of August.
b) As time goes by, the number of squirrels in the park will increase.

The line l is tangent to the circle with equation x² + y2 = 169 at the point P.
By thinking about the radius or otherwise, determine the gradient of the line l.
Given:
The equation of a circle is
[tex]x^2+y^2=169[/tex]
A tangent line l to the circle touches the circle at point P(12,5).
To find:
The gradient of the line l.
Solution:
Slope formula: If a line passes through two points, then the slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Endpoints of the radius are O(0,0) and P(12,5). So, the slope of radius is
[tex]m_1=\dfrac{5-0}{12-0}[/tex]
[tex]m_1=\dfrac{5}{12}[/tex]
We know that, the radius of a circle is always perpendicular to the tangent at the point of tangency.
Product of slopes of two perpendicular lines is always -1.
Let the slope of tangent line l is m. Then, the product of slopes of line l and radius is -1.
[tex]m\times m_1=-1[/tex]
[tex]m\times \dfrac{5}{12}=-1[/tex]
[tex]m=-\dfrac{12}{5}[/tex]
Therefore, the gradient or slope of the tangent line l is [tex]-\dfrac{12}{5}[/tex] .

1 pizza costs $0.50 to make. They sell it for $12. Find the percent markup.
Answer:
ok let me try this again
To explain a markup, let's use an example: Let's say you purchase a box of paper that costs one dollar. You aim for a profit of 50%. By multiplying the cost by 50%, you get $0.50. This is your markup price. Add that to the price that you paid to purchase the box of paper, and now the total is $1.50. This is the selling price of the box of paper. Therefore, your markup percentage is 50%.

Can you answer plz
у = х + 3
у =-2x-3
Answer:
x = - 2, y = 1
Step-by-step explanation:
Comparing both the equations,
→ y = y → x + 3 = - 2x - 3
=> x + 3 = - 2x - 3
=> x + 2x = - 3 - 3
=> 3x = - 6
=> x = - 6/3 = - 2
Substitute the value of x in any of these:
=> y = x + 3 = - 2 + 3 = 1
Answer:
Step-by-step explanation:
If a solution exists for the system of equations y=y so we can say
x+3=-2x-3 Add 2x to each side
3x+3=-3 Subtract 3 from each side
3x=-6. Divide each side by 3
x=-2, since y=x+3
y=-2+3
y=1
So the solution to the system of equations is the point (x,y)=(-2,1)

You have 84 feet of streamers. You cut 24 pieces that are each 1/2 yard long. How many feet of streamers do you have left?
Answer:
48
Step-by-step explanation:
If we have 84 feet of streamers. You cut 24 pieces that are each 1/2 yard long then 48 feet of streamers we left.
What is Unit of Measurement ?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
Given that we have a 84 feet of streamers.
You cut 24 pieces that are each 1/2 yard long.
Need to find the feet of streamers we left.
We know that 1 yard is equal to 3 feet.
Therefore, 1/2 yard is equal to 1.5 feet.
The total length of the streamers that were cut is:
24 pieces x 1.5 feet/piece = 36 feet
To find out how much streamer is left, we can subtract the length of the cut streamers from the total length we started with:
84 feet - 36 feet = 48 feet
Therefore, you have 48 feet of streamers left.

If nkf ~ lzf, find nf, please help me with this it’s due tmr!!!!
Answer:
NF = 25
Step-by-step explanation:
Since ∆NKF ~ ∆LZF, the ratio of their corresponding side lengths would also be the same.
This means that:
KF/ZF = NF/LF
KF = x + 3
ZF = 4
NF = 15 + x + 3 = x + 18
LF = x + 3
Plug in the values into the equation
(x + 3)/4 = (x + 18)/(x + 3)
Cross multiply
(x + 3)(x + 3) = (x + 18)(4)
x² + 3x + 3x + 9 = 4x + 72
x² + 6x + 9 = 4x + 72
x² + 6x + 9 - 4x - 72 = 0
x² + 2x - 63 = 0
Factorize to find x
x² + 9x - 7x - 63 = 0
x(x + 9) -7(x + 9) = 0
(x + 9)(x - 7) = 0
x + 9 = 0 or x - 7 = 0
x = -9 or x = 7
We'd use the positive value of x, which is 7.
Therefore, x = 7.
✅NF = 15 + (x + 3)
Plug in the value of x
NF = 15 + (7 + 3) = 15 + 10
NF = 25
