First off we need to use the formula S = rΘ
S - is the arc length
Θ - is theta which is the radian measure
r - is the radius
In this problem we need to find r
So, our equation would look like:
S ÷ Θ = r
Before we solve though, we need to convert the degrees to radians:
To convert from degrees to radians, multiply the degrees by π/180° radians:
60 x π/180 = 1.0472
If you input the numbers you get:
10.2 / 1.0472 = 9.740
The radius is 9.7 yards.
Answer:
Arectangle=27.68cm (approximately)
Step-by-step explanation:
<em>in order to find the area of the rectangle first you need to find the measure of the length and width.</em>
since both of them aren't given ,use trigonometry to find the value of the length and width.
sin30°=opposite/hypotenuse
sin30°=opposite/8cm
opposite=sin30°*8cm. >sin30°=0.5
opposite=4cm
cos30°=adjacent/hypotenuse
cos30°=adjacent/8cm
adjacent=cos30°*8cm. cos30°=0.866
adjacent=6.92cm (approximate value)
Arectangle= bh
Arectangle=4cm*6.92cn
Arectangle=27.68cm
Answer:
A
Step-by-step explanation:
the rest of the tables have two of the same numbers and it is not a function if it does that.
Answer:
what is 40 plus 60
Step-by-step explanation:
Answer:
1 ≤ x ≤ 6 Option A
Step-by-step explanation:
When graph is constant it means, value of graph ( y-values) not to be change different values of x in given interval.
In other words, graph must be parallel to the x axis is known as the constant graph.
A function is a measure of the rate of change of function values with respect to change in input values.
In given graph horizontal line is lie on the interval from x ≥ 1 to x ≤ 6.
So, option A is correct.
