Round off 24.67 to one significant
Answers
Answer:
The answer is: 20
Step-by-step explanation:
Significant figures are the meaningful digits that contribute to the precision and accuracy of the given number.
The given number: 24.67 has four significant figures because all the non-zero digits are significant.
Rounding off refers to the method of expressing the given number to the nearest whole number or nearest thousand, hundred, ten, etc.
Now, rounding off the given number (24.67) to one significant figure gives 20, which has only one significant figure. As the trailing zero is not significant.

Answer:
B) -3
Step-by-step explanation:
The zeros of the function are found easily from the factors. They are 6 and -12. The x-coordinate is halfway between them, at (6 + (-12))/2 = -6/2 = -3.
If you want a formula, consider a quadratic with roots (zeros) p and q. Then it factors as
... y = (x -p)(x -q)
The line of symmetry through the vertex is also the line of symmetry between the roots, so has x-coordinate:
... x = (p+q)/2
___
In your problem, you have p=6, q=-12, so x = (p+q)/2 = -6/2 = -3 is the line of symmetry and the x-coordinate of the vertex.
The vertex of a parabola is the minimum or the maximum point on the parabola
The x-coordinate of the vertex is -3
The equation is given as:
Open brackets
Differentiate
Set to 0
Collect like terms
Divide both sides by 2
Hence, the x-coordinate of the vertex is -3

3/4 h = 45min
1h = 60min
60min - 22min = 38min
45min = 38min + 7min
2:22AM + 45min = 2:22AM + 38min + 7min = 3:00AM + 7min = 3:07AM

Answer:
g(x) =
Step-by-step explanation:
Exponential function 'g' that can be written as g(x) = a.bˣ
From the graph attached,
Graph of the function passes through two points (0, 9) and (1, 3)
g(0) = a.b⁰
9 = a
Similarly, g(1) = a.b¹
3 = a.b
3 = 9(b)
b =
Therefore function will be,
g(x) =

Answer:
x = 12
Step-by-step explanation:
2 = 3/4x - 7
2 + 7 = 3/4x
9 = 3/4x
9 × 4x = 3
36x = 3
x = 36/3
x = 12
