I was given this graph:
1 answer:
The points on a graph are frequently used to represent the relationships between two or more objects.
The filled out table exists as follows:
Row 1 = 2, 4, 8
Row 2 = 6, 36, 216
<h3>What is meant by graph?</h3>A graph is a visual representation or diagram used in mathematics that displays data or values in an organized manner. The points on a graph are frequently used to represent the relationships between two or more objects.
In the first row we have x² = 4. Apply the square root to both sides to get x = 2. It appears your teacher is making x positive.
So we'll have 2 in the first box of row 1.
If x = 2, then x³ = 8 after cubing both sides.
In other words, x³ = 2³ = 2 × 2 × 2 = 8
The value 8 goes in the other box of row 1.
For row 2, we use x = 6 to square that to get x² = 6² = 6 × 6 = 36.
36 will go in the blank box for row 2.
The filled out table exists as follows:
Row 1 = 2, 4, 8
Row 2 = 6, 36, 216

The question is incomplete, the complete question is below:
Scientists have found a relationship between the temperature and the height above a distant planet's surface. , given below, is the temperature in Celsius at a height of kilometers above the planet's surface. The relationship is as follows: T(h) = 30.5 -2.5h.
a) Calculate T^-1(x)
b) T^-1(15)
Answer:
a)
b) 6.2 °C
Step-by-step explanation:
a)
b)
Regression line is given in the form of: y = a + bx
Where b is the gradient
Working out 'b'
Σxy - [ΣxΣy]/N
Σx² - [Σx]²/N
Working out 'a'
a = [∑y/N] - b[∑x/N]
a = [2650/460] - 0.264[3920/460]
a = 5.86 - 2.25
a = 3.61
Regression line equation is
y = 3.61 + 0.264x
Where b is the gradient
Working out 'b'
Working out 'a'
a = [∑y/N] - b[∑x/N]
a = [2650/460] - 0.264[3920/460]
a = 5.86 - 2.25
a = 3.61
Regression line equation is
y = 3.61 + 0.264x
