Answer:
6 in 2.
Step-by-step explanation:
Area = √s(s-a)(s-b)(s-c)
= √6×(6 - 4)×(6 - 3)×(6 - 5)
= 6 inches 2.
She should choose data 1! I can’t see the graph
Area of a circle: πr²
Data:
diameter: 21 cm
radius=diameter/2=21 cm/2=10.5 cm
area of this circle: π(10.5 cm)²=110.25π cm² (≈346.36 cm²)
Answer: area=110.25π cm²
Answer:
Option 1.
Step-by-step explanation:
The height of the tide over the time is shown on the graph.
Its a periodic function (sine graph) plotted on a graph in which variables are
Amplitude a = (6-0)/2 = 3
Period = 15-3 = 12
Therefore b = 2π/period = 2π/12 = π/6
horizontal shift = 0
Vertical shift = 3
Since the function starts with negative sign that means its below the x-axis.
So as per standard formula of f(x) = asin(bx+c)+d
option which matches all these parameters is Option 1.
