107 in the verse of 180 the whole turn will evaluate to 73.
Step-by-step explanation:
Diameter = 2*radius
14/2=7
Radius is 7in"
Circumference of circle formula: 2pi(radius)
2pi(7)= 43.98in of wire required so it can wrap around lamp exactly once.
Answer:
The equation of the quadratic function shown is;
x^2+ 2x -3
Step-by-step explanation:
Here in this question, we need to know the quadratic equation whose graph was shown.
The key to answering this lies in knowing the roots of the equation.
The roots of the equation are the solution to the quadratic equation and can be seen from the graph at the point where the quadratic equation crosses the x-axis.
The graph crosses the x-axis at two points.
These are at the points x = -3 and x = 1
So what we have are;
x + 3 and x -1
Multiplying both will give us the quadratic equation we are looking for.
(x + 3)(x-1) = x(x -1) + 3(x-1)
= x^2 -x + 3x -3 = x^2 + 2x -3
Answer:
$433.84
Step-by-step explanation:
First, find the amount of money Jennifer earned for regular work time:
8.50 x 43 = 365.50
Then, find the amount of money Jennifer earned for overtime work:
10.50 x 6.5 = 68.25
Finally, add them:
365.50 + 68.25 = 433.75
