x would be 6 because you double 5 to get ten, so you double 3 to get 6
The side across from the 63° angle is 299.5 ft and the side across from the 56° angle is 278.7 ft.
We will use the Law of Sines to solve this. First, the angle across from the 63° angle:
sin 61/294 = sin 63/x
Cross multiply:
x*sin 61 = 294 sin 63
Divide by sin 61:
(x sin 61)/(sin 61) = (294 sin 63)/(sin 61)
x = 299.5
For the side across from the 56° angle:
sin 61/294 = sin 56/x
Cross multiply:
x*sin 61 = 294 sin 56
Divide both sides by sin 61:
(x sin 61)/(sin 61) = (294 sin 56)/(sin 61)
x = 278.7
Answer:
1)
Area
2)
1/2
3)
Radius
Step-by-step explanation:
We know that for any circle with radius r the formula for the area and circumference of the circle is given as:
Area of circle=πr².
and circumference of circle = 2πr.
Hence, to describe the relationship between the area of a circle and its circumference.
The Area of circle is 1/2 times the radius times the circumference.
( Since,
Area=1/2 × r× 2πr
Area=πr² )
Answer: Relative error = 50%
Step-by-step explanation:
Relative error Re = Absolute error/True value × 100%
True value = 2 scoops
Measured(used) value = 3 scoops
Absolute error Ae = measured(used) value - True value
= 3 scoops - 2 scoops
Ae = 1 scoop
Re = 1/2 × 100%
Re = 50%
To get the maximum height, we first determine the time at which this maximum height is attained by differentiating the given equation and equating the differential to zero.
h(t) = -0.2t² + 2t
Differentiating,
dh(t) = -(0.2)(2)t + 2 = 0
The value of t is equal to 5. Substituting this time to the original equation,
h(t) = -0.2(5²) + 2(5) = 5 ft
Thus, the maximum height is 5 ft and since it will take 5 seconds for it to reach the maximum height, the total time for it to reach the ground is 10 seconds.
Answers: maximum height = 5 ft
time to reach max height = 5 seconds
time it will reach the ground = 10 s
