P(hemoglobin level between 9 and 11) = P(age between 25 and 35 years)..
Answer: The 12th term is 46x -25
Step-by-step explanation:
It is increasing by 4x and decreasing by 3 through each term, this represents the d. a1 has already been identified as 2x +8, so you just have to write down the formula and the solve form there by plugging in the 12 in (n-1) to find the answer.
3.572
Area of a circle in terms of radius:
Area = π · r2 = 3.14 · 1.072 = 3.57 square meters.
In terms of diameter:
Area = π · (d
2
)2 = 3.14 · (2.13
2
)2 = 3.14 · (1.07)2 = 3.57 square meters.
In terms of circumference:
Area = C2
4π
= 6.72
4π
= 44.89
(4 · 3.14)
= 44.89
12.56
= 3.57 square meters.
Note: for simplicity, some results may be rounded to nearest hundredth and π was rounded to 3.14. See formula details below in this page.
A circle of radius = 1.066 or diameter = 2.133 or circunference = 6.7 meters has an area of 3.572 square meters which is equal to:
3.572E-6 square kilometers (km²)
35720 square centimeters (cm²)
0.0008827 acres (ac)
0.0003572 hectares (ha)
1.379E-6 square miles (mi²)
4.272 square yards (yd²)
38.45 square feet (ft²)
