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°

Given the vertex (2, -1 )and the point(0,7), write the vertex form equation of the
quadratic function
Pls help!!!
Answer:
f(x) = 2(x - 2)² - 1
Step-by-step explanation:
Given the vertex, (2, -1) and the point, (0, 7), we can plug these values into the vertex form of the quadratic function:
f(x) = a(x - h)² + h
where:
vertex = (h, k)
a = determines whether the graph opens up or down, and the wideness or narrowness of the parabola.
h = determines how far left or right the parent function is translated.
k = determines how far up or down the parent function is translated.
We could substitute the given values into the vertex form, and solve for the value of "a":
f(x) = a(x - h)² + h
7 = a(0 - 2)² - 1
7 = a(-2)² - 1
7 = a(4) - 1
Add 1 to both sides:
7 + 1 = a(4) - 1 + 1
8 = 4a
Divide both sides by 4 to solve for a:
8/4 = 4a/4
2 = a
Since a = 2, and the vertex = (2, -1) then we could plug this value into the given function:
f(x) = 2(x - 2)² -1
Attached is a screenshot of the graph where it contains the given points.

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.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is 3x-7=38.
Solution to given equation is
3x=38+7
3x=45
x=15
The teacher say the answer is 6 less than the answer she found.
Which is x=9
The teacher says that Joan copied the coefficient of x incorrectly
If equation is 5x-7=38
5(9)-7=38
38=38
Therefore, the correct coefficient of x is 5 and the correct equation is 5x-7=38.

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.

A duck dives underwater and its path is described by the quadratic function y = 2x^2 - 4x, where y represents the position of the duck in meters and x represents the time in seconds. How long was the duck underwater?
Solving the quadratic equation, it is found that the duck was underwater for two seconds.
The path of the duck after x seconds is modeled by:
[tex]y = 2x^2 - 4x[/tex]
It is a concave up parabola, thus, the negative values of y, when he is underwater, are between the roots.
To find the roots:
[tex]y = 0[/tex]
[tex]2x^2 - 4x = 0[/tex]
[tex]2x(x - 2) = 0[/tex]
[tex]2x = 0 \rightarrow x = 0[/tex]
[tex]x - 2 = 0 \rightarrow x = 2[/tex]
2 - 0 = 2, thus, the duck was underwater for two seconds.

Answer:
Y = 58
X = 66
Step-by-step explanation:
So the markers mean that those sides of the triangle are congruent. Because of this, we know that the angles opposite from those sides are equal as well.
In the big triangle, Y will be equal to the empty angle. You can then use:
180 = 64 + 2*Y
Then, solving for Y, you get:
Y = (180-64)/2
Y = 58
You can use the same idea for the smaller triangle. The empty angle will be the same as the angle marked as 57.
180 = 57*2 + X
Then, solving for X, you get:
X = 180 - 57*2
X = 66
