Use quadratic regression to find
the equation of the parabola
going through these 3 points.
(-1,23), (1,-5), (3,-57)
y = [ ? ]x2 + [ ]x+ [ ]
Enter
Based on the information given, the required equation of parabola will be y= -3x² - 14x + 12.
SolutionThe parabola passes through the points (-1, 23), (1, -5), (3, -57). Let the equation of the parabola be y = ax² + bx + c.
For point (-1, 23), this will be:
23 = a(-1)² + b(-1) + c
23 = a - b + c ..... equation i
For point (1, -5), this will be:
-5 = a(1)² + b(1) + c
-5 = a + b + c .... equation ii
For point (3, -57), this will be:
-57 = a(3)² + b(3) + c
-57 = 9a + 3b + c .... equation iii
From equation i, 23 = a - b + c
Therefore, c = 23 - a + b .... equation iv
Substitute c into equation ii
-5 = a + b + 23 - a + b
-5 = 2b + 23
2b = -23 - 5.
2b = -28
b = -28/2 = -14
Substitute c into equation iii
-57 = 9a + 3b + 23 - a + b
-80 = 8a + 4b.
-80 = 8a + 4(-14)
-80 = 8a - 56
8a = -80 + 56
8a = -24
a = -24/8 = -3
Therefore, the value of c will be:
c = 23 - a + b
c = 23 -(-3) + (-14)
c = 23 + 3 - 14
c = 12
In conclusion, the required equation of parabola will be y = -3x² - 14x + 12.

Joan can't quite read the board in her math class. She writes down the equation she reads on the
board as 3x – 7 = 38. She correctly solves the equation she wrote down, but is surprised to hear the
teacher say the answer is 6 less than the answer she found. When she asks the teacher to check her
work, the teacher says that Joan copied the coefficient of x incorrectly (but copied everything else
correctly). What should the coefficient of x have been?
Answer:
x = 15
Step-by-step explanation:
3x - 7 =38
3x = 38+7
3x = 45/3
x = 15
The correct coefficient of x is 5 and the correct equation is 5x-7=38.

If m<18 = 46° and m<13 = 69°, calculate m<10.
Answer:
m<10 = 65°
Step-by-step explanation:
I. Given m<18 = 46deg, m<13 = 69deg and m<10 = x
The degree is less than 90deg, so this triangle is acute triangle.
Sum of degree inside of triangle is 180°
So 46 + 69
= 115
Find x by
180 - 115 = 65
So m<10 = 65°

Use the figure below to answer the following questions.
What is m∠1?
60
30
90
120
Answer:
30
Step-by-step explanation:
1. The exterior angle theorem states that the two opposing (in terms of the exterior angle) interior angles of a triangle are congruent to the exterior angle. This means that m∠1 (x) + 90 = 120. Now, we just have to solve for x.
2. (Solving)
Step 1: Subtract 90 from both sides.
[tex]x + 90 = 120[/tex] [tex]x - 90 = 120 - 90[/tex] [tex]x = 30[/tex]Step 2: Check if solution is correct.
[tex]30 + 90 = 120[/tex] [tex]120 = 120[/tex]Therefore, m∠1 = 30 degrees.
Answer:
∠ 1 = 30°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is the exterior angle of the left triangle , then
∠ 1 + 90° = 120° ( subtract 90° from both sides )
∠ 1 = 30°
