A teacher keeps track of the number of students that participate at least three times in an optional study session each year. He models the attendance over the last nine years with this function.
n(t) = 3.53t^2 - 33.04t + 117.56
Which graph would most likely be associated with the given model?
Regression equations can be linear, quadratic or exponential
The graph that would most likely be associated with the given model is (b)
The regression equation is given as:
[tex]n(t) = 3.53t^2 - 33.04t + 117.56[/tex]
The above regression equation is a quadratic function (and non-linear).
So, the graph must represent a non-linear relationship.
From the given graphs, only graph (b) represents a quadratic function.
Other options are either linear models or exponential.
Hence, the graph that would most likely be associated with the given model is (b)

Diana invested $3000 in a savings account for 3 years. She earned $450 in interest over that time period. What interest rate did she earn? Use the formula I=Prt to find your answer, where I is interest, P is principal, r is rate and t is time. Enter your solution in decimal form rounded to the nearest hundredth. Fr example, if your solution is 12%, you would enter 0.12.
Answer:
0.05
Step-by-step explanation:
we are given the formula
I = Prt, where
I = interest earned = $450
P = Principal amount = $3000
t = time = 3 years
r = rate (we are asked to find this_
Simply substitute the known values into the equation
I = Prt
450 = 3000 x r x 3
450 = 9000r
r = 450/9000
r = 0.05

Which of the following is the inverse of f(x)=3-x/5
Answer:
f^-1(x) = 3 - 5x, second option
Step-by-step explanation:
To determine the inverse simply interchange the variables and solve for y;
f(x) = 3 - x / 5 -> Interchange the variables
x = 3 - y/5 -> Multiply either side by 5
5x = 3 - y -> Subtract three from either side
- y = 5x - 3 -> Divide either side by - 1
y = - 5x + 3
Your solution is f^-1(x) = 3 - 5x
The number of trout in America since 2000 is given by the following formula:
[tex]y=x^2+3x+2[/tex]
"x" is the number of years and "y" is the number of trout in the millions.
Based on this formula, estimate the number of trout in the years 2005, 2010, and 2015.
Describe the trend in the number of trout as the years increase.
Answer:
See below
Step-by-step explanation:
Given formula
y = x² + 3x + 2x- is the number of years after 2000,y - is the number of troutYear 2005, finding number of trout
x = (2005 - 2000) = 5y = 5² + 3*5 + 2 = 42 millionsYear 2010, finding number of trout
x = (2010 - 2000) = 10y = 10² + 3*10 + 2 = 132 millionsYear 2015, finding number of trout
x = (2015 - 2000) = 15y = 15² + 3*15 + 2 = 272 millionsNumber of trout is trending up with significant increase over yeas
Answer:
42 million132 million272 millionThe number of trout inceases a lot each 5 years that pass.Step-by-step explanation:
Number of trout in 2005.
Find the number of years apart from 2000 to 2005.
2005 - 2000 = 5
Substitute for x and solve for y.
y = x² + 3x + 2
y = (5)² + 3(5) + 2
y = 25 + 15 + 2
y = 40 + 2
y = 42 million
Number of trout in 2010.
Find the number of years apart from 2000 to 2010.
2010 - 2000 = 10
Substitute for x and solve for y.
y = x² + 3x + 2
y = (10)² + 3(10) + 2
y = 100 + 30 + 2
y = 130 + 2
y = 132 million
Number if trout in 2015.
Find the number of years apart from 2000 to 2015.
2015 - 2000 = 15
Substitute for x and solve for y.
y = x² + 3x + 2
y = (15)² + 3(15) + 2
y = 225 + 45 + 2
y = 270 + 2
y = 272 million

Answer:
y=0x-1
Step-by-step explanation:
Slope-int form: y=mx+b
Both points have the same y value and different x values, so the slope (m) is 0.
