Which function best fits the following points?
A. y= -12.84032 + 0.0225x
B. y = 65.0778 × 772.9605^x
C. y = -197.0571x^2 + 245.6243x + 6.0321
D. None of the above
Given:
The graph of a scatter plot.
To find:
The function that best fits the given points.
Solution:
From the given graph it is clear that the linear function is the best fit for the given points because the points lie on a straight line or near to it.
So, options B and C are incorrect because they represent exponential and quadratic function respectively.
Let as assume the two points on the graph are (0.80,-12.82) and (2,-12.79).
Using this two points, the equation of line is:
[tex]y-(-12.82)=\dfrac{-12.79-(-12.82)}{2-0.80}(x-0.80)[/tex]
[tex]y+12.82=\dfrac{-12.79+12.82}{2-0.80}(x-0.80)[/tex]
[tex]y+12.82=0.025(x-0.80)[/tex]
[tex]y+12.82=0.025x-0.02[/tex]
[tex]y=0.025x-0.02-12.82[/tex]
[tex]y=0.025x-12.84[/tex]
[tex]y=-12.84+0.025x[/tex]
It is the approximate function to the function that is in option A.
Therefore, the correct option is A.

91. Jack can read 45 pages of his book in one and a
half hours. At that rate, how long will it take him to
read the entire 300-page book?
Answer:
10 hours
Step-by-step explanation:
45 pages per 1 hour and 30 minutes, or 60 min +30 min =90 min
90 minutes / 45 pages has to be equal to an equivalent fraction where we have 300 pages
90 minutes /45 pages = ? minutes / 300 pages , multiply both sides by 300
? minutes = 90*300/45 = 600 minutes
to read 300-page book will take 600 minutes = 10 hours

I have two hours to get this done please help me I’ve been stuck on this problem
Answer:
The answers are all bolded below. If you can, please read the explanation so you can pass a test if asked.
Step-by-step explanation:
First, the quadratic equation we are starting with is -x^2 + 10x + 9.5
-------------------------------------------------------------------------------------------
For the first part, it's asking for how high it is when it starts, commonly, we use 0 as the start point so if we plug 0 into the quadratic equation, we have 9.5. The height is 9.5 feet at start.
-------------------------------------------------------------------------------------------
For the second part I'm assuming it's asking for either a minimum or a maximum and because the equation has a -x^2, that means the parabola has a maximum. You can tell by -x^2 being negative, if it was x^2 (positive) it would have a minimum.
The maximum is found using the vertex formula(because the vertex is the max or min), -b/2a, where a is -1, b is 10, and c is 9.5 found in the equation because the quadratic is in standard form ax^2 + bx + c. This gives a vertex of 5.
We plug 5 back in the equation to get (5, 34.5).
5 is the x-coordinate so it is 5 feet horizontally and 34.5 feet high
--------------------------------------------------------------------------------------------
For the last part it's asking for a root, or when the parabola touches the x axis/the ground.
-x^2 + 10x + 9.5
You would use the quadratic formula but I'm too lazy so I just put it into a calculator.
That gives roots of around x=−0.87367 and x=10.8737.
You can't have a negative root so you're left with x= 10.8737, rounding to the tenth decimal place, 10.9.
I think that's correct, could be wrong, if it is wrong just follow the steps and it should be fine.

The population of a place in a particular year increased by 15% next year it decreased by 15%. Find the net increase or decrease percent in the initial population
Answer:
there was a decrease of 2.25%
Step-by-step explanation:
Let me illustrate with an example
Assume the population is 100
percentage increase = 100 + 15 = 115% = 1.15%
Population after 15% increase = 100 x 1.15 = 115
Percentage decrease = 100 - 15 = 85% = 0.85
Population after 15% decreases 115 x 0.85 = 97.75
rate of increase = (97.75 / 100) - 1 = -2.25%

A man was traveling by air is allowed a maximum of 20kg luggages .The man has four bags weighing 3.5kg ,15 kg ,2kg and 1.5kg .Find excess weight of his luggage. 2 . Express the excess weight as a percentage of his maximum weight allowed.
Answer:
See explanation
Step-by-step explanation:
Maximum weight = 20 kg
Bag 1 = 3.5kg
Bag 2 = 15 kg
Bag 3 = 2kg
Bag 4 = 1.5kg
Total weight of bags = 22 kg
Excess weight of his luggage = Total weight of bags - Maximum weight
= 22 kg - 20 kg
= 2 kg
Express the excess weight as a percentage of his maximum weight allowed = excess weight / maximum weight × 100
= 2/20 × 100
= 0.1 × 100
= 10%
Express the excess weight as a percentage of his maximum weight allowed = 10%

Which shapes have the greatest area?
(Select all that apply.)
Answer is 1st and 3rd shape
Whose area is 4 units
Answered by Gauthmath must click thanks and mark brainliest
What is the area of this figure?
Answer:
Step-by-step explanation:
if you connect the 2 pointy parts of this shape at the top, what you have is a square. That means that the cut out part is a half circle. To find the area of the shaded portion, subtract the area of the half circle from the area of the square. Let's start with the square, cuz that's the super easy one.
A = s*s so
A = 64 in squared.
Now for the half circle. Let's just do this: let's find the area of the whole circle and then cut it in half, how about?
If the length of one of the sides is 8, then half that length is 4, right? Since the circle is touching the sides of the square, the diameter of the circle is the same as the measure of the side of the square. That means that the radius is 4. The area for the circle is
[tex]A=\pi r^2[/tex] and filling in:
[tex]A=(3.14)(4^2)[/tex] so
A = 50.24 in squared. Divide that in half and the area of half the circle is 25.12 in squared.
Subtract 25.12 from 64 to get 38.88 in squared
18. Which ordered pair is a solution of the system of linear equations listed below?
2x + y = -5
-x+3y=6
A. (-3, 1)
B. (3, 1)
C. (-3,-1)
D. (-1,3)
Answer:
A
Step-by-step explanation:
Given the 2 equations
2x + y = - 5 → (1)
- x + 3y = 6 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate the x- term
- 2x + 6y = 12 → (3)
Add (1) and (3) term by term to eliminate x
0 + 7y = 7
7y = 7 ( divide both sides by 7 )
y = 1
Substitute y = 1 into either of the 2 equations and solve for x
Substituting into (1)
2x + 1 = - 5 ( subtract 1 from both sides )
2x = - 6 ( divide both sides by 2 )
x = - 3
solution is (- 3, 1 ) → A

PLEASE HELP!!! Find the value of x.
A. 11
B. 5
C. 25
D. 31
Answer:
C
Step-by-step explanation:
Consider trapezoid ABCD with
A is the midpoint of ED
C is the midpoint of BF
=> AC is the median of trapezoid EBFD
=>(EB+DF) / 2 = AC
=>(13+x) / 2 = 19
=> 13+x = 38
=> x= 25
The value of x is 5.
According to the Triangle Proportionality Theorem, if a line is parallel to one side of a triangle and intersects the other two sides, it divides those two sides proportionally. In mathematical terms, we can express this as:
(a/b) = c
Where the values of a = 13, b = 19
Now, we can substitute the given values into the proportionality equation:
(13/19) = c
Next, we can cross-multiply the equation:
c = 0.68
Then the value of x is calculated by adding 4.32 on it then we get the value of x as
=> x = 0.68 + 4.32
=> x = 5
Hence the correct option is (b).

Hi there!
Looking at the graph, the first intersection point is clear. The red parabola and blue line clearing intersect at the point (0, -1).
Find the second intersection point by setting the equations of both graphs equal to each other.
Line: y = 3x - 1
Parabola: y = 4x² - 1
Find another intersection point by setting these two equations equal to each other:
4x² - 1 = 3x - 1
Bring all terms onto one side:
4x² - 3x = 0
Factor out x:
x(4x - 3) = 0
Set 4x - 3 to 0 and solve:
4x - 3 = 0
4x = 3
x = 3/4
Plug in this value of x into an equation to solve for the y-coordinate. Use the linear equation for ease:
y = 3(3/4) - 1
y = 9/4 - 1
y = 5/4

5. The distance between two given points (5,2) and (x,5) is 5 units. Find the possible values of x. *
============================================================
Explanation:
We'll use the distance formula here. Rather than compute the distance d based on two points given, we'll go in reverse to use the given distance d to find what the coordinate must be to satisfy the conditions.
We're given that d = 5
The first point is [tex](x_1,y_1) = (5,2)[/tex] and the second point has coordinates of [tex](x_2,y_2) = (x,5)[/tex] where x is some real number.
We'll plug all this into the distance formula and solve for x.
[tex]d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\5 = \sqrt{(5-x)^2+(2-5)^2}\\\\5 = \sqrt{(5-x)^2+(-3)^2}\\\\5 = \sqrt{(5-x)^2+9}\\\\\sqrt{(5-x)^2+9} = 5\\\\(5-x)^2+9 = 5^2\\\\(5-x)^2+9 = 25\\\\(5-x)^2 = 25-9\\\\(5-x)^2 = 16\\\\5-x = \pm\sqrt{16}\\\\5-x = 4 \ \text{ or } \ 5-x = -4\\\\-x = 4-5 \ \text{ or } \ -x = -4-5\\\\-x = -1 \ \text{ or } \ -x = -9\\\\x = 1 \ \text{ or } \ x = 9\\\\[/tex]
This means that if we had these three points
A = (5, 2)B = (1, 5)C = (9, 5)Then segments AB and AC are each 5 units long.

What is the explicit formula for this sequence?
6, 2, -2, -6, ...
Answer:
B
Step-by-step explanation:
this is just common sense. if you would have tried you could have easily answered this yourself.
the sequence starts with 6. that is a1.
so, the formula simply has to add "something" to 6.
therefore, A and D are out.
and then we see immediately that the sequence is built by subtracting 4 (or adding -4) for every step.
so, we need to add multiples of -4.
therefore, only B is correct (C adds multiples of +4).
