Answer:
y-values of sampled wave:
0, 5, 5, -3, -5, -3, 2, 0, 0, -1, -2, 1, 1, -1, -1, -2, 2, 3, -1
Step-by-step explanation:
My teacher told me to put a dot on very cross or intersection that the line is on.
I think all you need to do is rise/run, in this case, 2420÷6050=0.4=40%
Answer:
The answer is -1.
Step-by-step explanation:
You have to apply gradient formula :
So you will have to substitute the coordinates into the equation. Let (x1,y1) be (-3,4) and (x2,y2) be (5,-4) :
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)
5537 square inches (in²)
