Answer:
The circumference of the circle to the nearest tenth is 87.9
Step-by-step explanation:
In order to find the circumference using the diameter, you multiply the diameter times pi which is 3.14. 28*3.14 equals 87.92 which rounded to the nearest tenth is 87.9.
Answer:
The picture where the red image is the skinniest
Step-by-step explanation:
The graph P(x) denotes the graph of the parent graph for all the functions. And, It includes the vertex of (0,0) and points which are shown below:
x f(x)
-2 2
-1 1
0 0
1 1
2 2
Now as we can see in the attached figure i.e it changed the function points i.e given below for l(x) = 12P(x)
x f(x)
-2 24
-1 12
0 0
1 12
2 24
This depicts that it has a skinner graph that includes redish graph
Answer:
-3/5-13i/10
Step-by-step explanation:
PART A:
Scientific notation is given by A×10ⁿ where A is any number in a unit and 'n' is an integer.
0.000025 = 2.5×10⁻⁵
PART B:
Diameter of grain of sand ÷ Diameter of human body average cell
(2×10⁻⁴) ÷ (1×10⁻⁵)
(2÷1) × (10⁻⁴÷10⁻⁵)
2 × (10⁻⁴ ⁻ ⁻⁵) = 2 × 10⁽⁻⁴⁺⁵⁾ = 2 × 10¹ = 20 times bigger
PART C:
The diameter of human body's average cell in nanometer
1 × 10⁻⁵ metre = 1 × 10⁻⁵ × 10⁹ = 1 × 10⁽⁻⁵⁺⁹⁾ = 1 × 10⁴ nanometer
PART D:
Smallest bacteria = 300 nanometer
300 nm = 300 ÷ 10⁹ = (3 × 10²) ÷ 10⁹ = 3 × (10²⁻⁹) = 3 × 10⁻⁷ meter
PART E:
Laws of exponents that are applied in scientific notation is
xᵇ × xᵃ = x⁽ᵇ⁺ᵃ⁾
xᵇ ÷ xᵃ = x⁽ᵇ⁻ᵃ⁾
