Answer:
The circumference formula for a circle is C=πd where C is the circumference, d is the diameter of the circle and π is a constant. If you plug in 6 for C and solve the equation for d like:
6= πd and then divide both sides of the equation by π you get that d = 1.90
To find the central angle of an arc you would use the equation S = rθ where S is the length of the arc, r is the radius of the circle, and θ is the measure of the angle which in this case is unknown. So with S = 1 and r = d/2 = 1.90/2 = 0.9549 you would have an equation that looks like this:
1 = 0.9549θ.
If you divide both sides of the equation by 0.9549 you get θ = 1.047197 radians.
The question asked for the angle measure in degrees so you would need to convert the angle measure to degrees by multiplying the degree measurement by 180/π
1.047197 x 180/π = 60°
Answer:
The ellipse is not the graph of a function.
Step-by-step explanation:
If you can draw a vertical line on the graph that intersects the graph in two or more points, the relation shown is <em>not a function</em>.
A vertical line will intersect the ellipse at two points (unless it is tangent to an end of the major axis), so the ellipse is not the graph of a function.
X = how much Tim has
y = how much Tom has
x + y = 2.40
x = 3y
Substitute 3y for x
3y + y = 2.40
4y = 2.40
y = 0.60
Plug in y value into previous equation
x = 3(0.60)
x = 1.80
ANSWERS: Tim has $1.80 and Tom has $0.60
Answer:
Step-by-step explanation:
<u><em>The correct question is</em></u>
Solve. −3/5x+1/5>7/20 Drag and drop a number or symbol into each box to show the solution
we have
Solve for x
Multiply by 20 both sides
subtract 4 both sides
divide by -12 both sides
Remember that when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
simplify
Step-by-step explanation:
As we can see the question given
f(x) is varying accordingly to the interval
<em> f(x) = 2 if 2<x≤4</em>
The value of function is 2 for the interval 2 to 4
and interval is open at x=2 and closed at x = 4
<em> f(x) = x + 3 if 4<x<8</em>
The value of function is x + 3 and it is open at x = 4 and x = 8
<em>f(x) = 2x if x 
8</em>
The value of function is 2x for x greater than or equal to 8
