Applying a quadratic regression model y = ax2 + bx + C,
what are the values of a, b, and c?
O a = 0.248, b = 0.994, c = 2.979
O a= 2.979, b = 0.994, c = 0.248
O a = 0.248, b = -0.994, c = 2.979
O a = 2.979, b= -0.994, c = 0.248
What is the velocity of a car that traveled a total of 75 km north in 1.5 hours
Answer:
13.89 m/s
Step-by-step explanation:
Velocity = displacement = time
75 km = 75000 m
1.5 hours = 5400 sec
applying the formula
velocity = 75000 m= 5400 s = 13.89 m/s
Answer:
Velocity= Displacement / Time
= 75/1.5
=50km/hr

31) Multiply the entire equation by the LCM of 5 & 4 which is 20
[tex]20*\dfrac{2x^{2}}{5}+20*\dfrac{5x}{4}=10*20\\\\4*2x^{2}+5*5x = 200\\\\8x^{2}+25x - 200 = 0[/tex]
B
32) D
By trial & error method 17 * 15 = 255
33) x = 2
y = 4x² + 1
= 4*2² + 1 = 4*4 + 1
= 16 + 1
y = 17
B
34) D) all real numbers
35) Domain = all real numbers,
x = -2 ; y = -(-2+2)² - 7 = 0 - 7 = - 7
x = 0 ; y = -(0+2)² - 7 = -4 - 7 = -11
x = 4; y = -(4+2)² - 7 = - 6² -7 = -16 - 7 = - 23
C) y ≤ -7
36) t = 1 second
y = 160t - 40t² = 160*1 - 40*1² = 160 - 40
y = 120 m
C
37) Let the number be 'x'
x² + x = 165
x² + 4x - 165 = 0
Sum = 4
Product = -165
Factors = 15 , -11 {15*(-11) = -165 & 15+ (-11) = 4}
x² + 15x - 11x - 165 = 0
x(x + 15) - 11(x + 15)=0
(x + 15)(x - 11) = 0
x + 15 = 0 ; x - 11 = 0
x = -15 ; x = 11
C
38) y = 3(x + 1)² - 2
Plugin x = -1 ; y = 3(-1 +1)² - 2 = 0 - 2
y = -2

What’s mean number basic statistics btw
Answer:
To find the mean, add up the values in the data set and then divide by the number of values that you added. To find the median, list the values of the data set in numerical order and identify which value appears in the middle of the list. To find the mode, identify which value in the data set occurs most often.

Find the midpoint M of the line segment joining the points S = (7, -2) and T = (-3, -8).
Answer:
(2, -5)
Step-by-step explanation:
Using the midpoint formula - M= [tex](\frac{x_{1} +x_{2} }{2}, \frac{y_{1}+y_{2} }{2} )[/tex], we get that the x value of the point is 2 and the y-value of the midpoint is -5, so the midpoint of segment ST is (2, -5)

Given s = 2.4 b = -7.2 t = 4.8 n = -9.6, evaluate this mathematical expression (s - b)(n + t).
These are the answer options:
23.04
-23.04
46.08
-46.08
Answer: Fourth Choice. -46.08
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
Given information
s = 2.4
b=-7.2
t=4.8
n=-9.6
Given expression
(s - b) (n + t)
Substitute values into the expression
= (2.4 - (-7.2)) (-9.6 + 4.8)
Simplify values in the parentheses
= (2.4 + 7.2) (-4.8)
=(9.6) (-4.8)
Simplify by multiplication
= [tex]\boxed{-46.08}[/tex]
Hope this helps!! :)
Please let me know if you have any questions
Answer:
- 46.08Step-by-step explanation:
Given Values :-
s = 2.4
b = - 7.2
t = 4.8
n = - 9.6
Substituting the given values in the equation :-
= > ( s - b ) ( n + t )
= > ( 2.4 - ( - 7.2 ) ) ( - 9.6 + 4.8 )
= > ( 2.4 + 7.2 ) ( -4.8 )
= > ( 9.6 ) ( - 4.8 )
= > - 46.8

Answer:
A. f(x) = x^2 -3x -10
Step-by-step explanation:
You can easily determine the correct equation by looking at a couple of table values.
The y-value for x=0 is -10, which is the constant in the quadratic formula. (eliminates choices B and C)
The y-value for x=1 is -12, which is the sum of coefficients in the quadratic formula. For choice A, the sum of coefficients is 1 -3 -10 = -12. For choice D, the sum of coefficients is 1 +3 -10 = -6. The value for choice D does not match the table, but the value for choice A does.
The function that represents the table is ...
f(x) = x^2 -3x -10
_____
Additional comments
If you don't have equations to test, and you want to write your own equation, there are a couple of ways to do that. One is to look at the differences of y-values, and the differences of those.
The sequence of y-values shown is ...
30, 18, 8, 0, -6, -10, -12
The sequence of differences of these numbers, starting with 18-30 = -12 is ...
-12, -10, -8, -6, -4, -2
The sequence of differences of these numbers is ...
2, 2, 2, 2, 2
The fact that they are constant tells you a quadratic (degree = 2) will describe the table.
We can find the coefficients a, b, c in the quadratic formula f(x) = ax^2 +bx +c as follows. First, we define d1 as the first of the sequence of differences (-12), and d2 as the value of the second differences (2). And we'll let x0 and y0 be defined as the first of the x-values (-5) and y-values (30).
The formulas for the coefficients (a, b, c) can be found from ...
a = (d2)/2 = 2/2 = 1
b = (d1) -a(2·(x0) +1) = -12 -1(2·(-5) +1) = -12 +9 = -3
c = y0 -x0(a·x0 +b) = 30 -(-5)(1·(-5) +(-3) = 30 -40 = -10
As we noted above, the y-value corresponding to x=0 is also this c value. When the table includes x=0 and x=1, those can be used to simplify the finding of the formula coefficients.
These computations tell us f(x) = x^2 -3x -10, as above.
__
If you have to do this again, it might be useful to make a note of the expressions for 'a', 'b', and 'c' that we showed here, along with the definitions of the variables we used in them.
__
Another way to find the formula for f(x) is to make use of a calculator or spreadsheet capable of quadratic regression. Give it three (x, y) pairs from the table, and it can tell you the formula coefficients. This is illustrated by the attachment.
19. Ryan bought 5 boxes of cereal and spent $9.45. Solve
the equation 5b= 9.45 to find the cost of each box.
Answer:
$1.89
Step-by-step explanation:
Given Equation:
5b=9.45
What are we looking for?
b
We must solve by making b by itself:
5b=9.45
÷5 ÷5
b = 9.45/5
b = 1.89
Therefore, each box of cereal costs $1.89

Answer:
[tex]\frac{1+\sqrt{5} }{2}[/tex] or 1.62
Step-by-step explanation:
A cool thing about the fibonacci sequence is that if you divide two consecutive numbers, the larger they are, they approach the golden ratio. This means the approximate value would be the golden ratio which is [tex]\frac{1+\sqrt{5} }{2}[/tex].
