Answer:
The per-pupil spending will be approximate $8,300 in 4 years
Step-by-step explanation:
Exponential Model
The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the current quantity.
An exponential decaying function is expressed as:
[tex]C(t)=C_o\cdot(1-r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The statistics of the years 2019-2020 at North Carolina indicate initial spending of Co=10,632 per student. The decaying rate is r=6% = 0.06 per year, thus the exponential model is:
[tex]C(t)=10,632\cdot(1-0.06)^t[/tex]
[tex]C(t)=10,632\cdot(0.94)^t[/tex]
where t is expressed in years.
We are required to know the expected spending for t= 4 years. Substitute t=4:
[tex]C(t)=10,632\cdot(0.94)^4\approx 8,300[/tex]
The per-pupil spending will be approximate $8,300 in 4 years
Find the solution to y. For your answer just write the number do not write any symbols or variables. For instance if x = 2, just write 2 in the answer box provided.
-10 + y = 3
Answer:
Step-by-step explanation:
-10 + y = 3 Add 10 to both sides
-10+10+y = 3 + 10 Combine
y = 13
So the answer is 13
You have to do something to get the answer. Algebra is based on logical steps. You don't learn much by seeing 13.

What is the equation of the line that passes through the point (6,-4) and has a
slope of -1/6
Answer:
y = -1/6x-3
hope this helps
Answer:
x+6y+18=0
Step-by-step explanation:
we have to use (y-y1)=m(x-x1)
now,(x1,y1)=(6,-4),m=-1/6
so, (y+4)=-1/6(x-6)
or,6y+24=-x+6
or,x+6y+24-6=0
x+6y+18=0 is the required equation.
What is the coordinate of point P on the line segment AB that is 3/4 of the distance from A to B for A(2,5) and B(6,9)?
Answer:
p is (3.71, 6.71)
Step-by-step explanation:
Given that p is at the distance of 3/4 from A to B
it mean that point p divides the line AB into 3:4 ratio.
and
if there are two points (x1,y1) and (x2,y22) which is divided by point p in the ratio m:n then
coordinates of point p (x,y) is given
p (x = (n*x1+m*x2)/m+n , y = (n*y1+m*y2)/m+n )
________________________________________________
Given the points AB
A(2,5)
B(6,9)
m:n = 3:4
thus,
p (x = (4*2+3*6)/7 , y = (4*5+3*9)/7 )
p (x = (4*2+3*6)/7 , y = (4*5+3*9)/7 )
p (x = (26/7 , y = 47/7 )
P ( x = 3.71, y = 6.71)
Thus, coordinates of point p is (3.71, 6.71) which is at 3/4 of the distance from A to B for A(2,5) and B(6,9)/
What is the lowest range of the function shown on the graph?
Answer:
C.-2
Step-by-step explanation:
The vertex is at (3,-2), this can find the lowest range because since both sides of the function go up from this point there will be no points beneath it. Since the range is Y value the minimum would be -2 because this is the Y value of the vertex. You can check the graph to prove this because there are not any y-values equal to less than -2.
find the x and why intercepts of the graph of the equation x + 2y = 10
NEED HELP ASAP
Answer:
Step-by-step explanation:
To find the x-intercept and y-intercept of the equation we need to understand what is an intercept. Intercept means to intersect/cut so x-intercept means the equation cuts the x-axis and y-intercept means the equation cuts the y-axis.
So if the equation cuts the x-axis the coordinate should be [tex](x,0)[/tex] and if the equation cuts the y-axis the coordinate should be [tex](0,y)[/tex] , and since the equation satisfies these both points in other words these two points lie on the line they can be put into the equation. So here we go,
For x-intercept
[tex]x+2y=10\\x+2(0)=10\\x=10[/tex]
so the x-intercept is (10,0)
For y-intercept
[tex]x+2y=10\\0+2y=10\\2y=10\\y=10/2\\y=5[/tex]
so the y-intercept is (0,5)
I also have attached an example of how intercepts looks like you can take a look i plotted the graph an you can see our answers check out.

MiniMouse received an order of bows for her store. The order had 3 boxes containing bows and 2 bows that were not in a box. Each box contained an equal number of bows. The order had 146 bows. What is n, the number of bows which should be in each box? Write and solve the equation.
Answer:
Step-by-step explanation:
If Mini has a total of 146 bows, then you should subtract 2 because those are not in the boxes.
146 - 2 = 144 144 ÷ 3 = 48. This means that there are 48 bows in each box.

Rory is at the local mall and her favorite type of jeggings are on sale. The jeggings are now
priced at $7 per pair, tax free. She has $27 with her, but she needs to have $6 leftover to
spend on a movie theater ticket.
Which inequality represents how many pairs of jeggings Rory can buy, where / represents
the number of jeggings?
Answer:
j ≤ 3
Step-by-step explanation:
Since she has $27 with her and needs a balance if $6, the amount of money she can spend on buying the jeggings will be $27-$6 = $21
This means that she has $21 to spend on buying the jeggins
From the question, one jeggings cost $7, so the maximum number of jeggings she can buy is 21/7 = 3
So the inequality that represents this will be;
j ≤ 3
This is because she can decide to buy less than 3, but never can she buy more than 3 because of her budgetary constraints
Given h(x)=-3x-2,solve for x when h(x)=1
Answer:
-5
Step-by-step explanation:
The value of x for the given function h(x)=-3x-2 such that h(x) = 1 will be -1.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.
As per the given funciton,h(x) = -3x - 2
For h(x) = 1
1 = -3x - 2
1 + 2 = -3x
3 = -3x
x = -1
Hence "The value of x for the given function h(x)=-3x-2 such that h(x) = 1 will be -1".

Complete the equation of the line through(−6,−5),(-4,-4)
Answer:
y=ax+b
bring in (-6,-5)
=>-5=-6a+b
=>6a-5=b
bring in (-4,-4)
=>-4=-4a+b
=>4a-4=b
b=6a-5=4a-4
6a-5=4a-4
2a=1
a=1/2
then b=6*(1/2)-5=-2
y=ax+b
=>y=(1/2)x-2
