I tried my best at it and my guess is that in standard form is 0.00086
Answer:
A≈28.26 in^2
Step-by-step explanation:
We know the diameter is 6
We can find the radius
r = d/2
r =6/2 =3 inches
The area of a circle is given by
A = pi *r^2
A = pi*3^2
A = pi*9
We will use 3.14 to approximate pi
A ≅(3.14) *9
A≈28.26 in^2
3x - 4y = 18 ⇒ 3x - 4y = 18
2x + y = 1 ⇒ 8x + 4y = 4
11x = 22
11 11
x = 2
2x + y = 1
2(2) + y = 1
4 + y = 1
- 4 - 4
y = -3
(x, y) = (2, 3)
Answer:
instead of just pointing out the highest speed or one speed, list all the different speeds or increasing/decreasing and the different intervals
ie for minutes 2 to 3, her speed was 30 mph . . . from minutes 6 to 8, her speed was decreasing at a constant rate of -2 mph/min
