Answer:
$57.50
Step-by-step explanation:
find 10% of 50 first, which is 5, because 5 × 10 = 50, then add $10 to the $50 beacause 50 × 0.2 = 10, next, remove 5%, to do this divide 10% by 2 to get $2.50, 60 - 2.5 = 57.5

An equation of the circle with center (h, k) and radius r:

Step-by-step explanation:
Not sure what you need to find out but,
An equation of the circle with center (h, k) and radius r:

Answer:
x= -5 + 5
, x= -5 - 5
Step-by-step explanation:
Since this quadratic is set to zero, we can use the quadratic formula to solve this.
x^2 + 10x - 2400 = 0
Quadractic formula = x= -b +-
/2a
For this equation:
a= 1, b=10, c=-2400
Plug these numbers into the equation and solve.
x= -10 +-
)/2(1)
x= -10 +-
/2
x= -10 +-
/2
x= -10 +-
/2
x= -10 +- 5 * 2
/2
x= -10 +- 10
/ 2
Divide by 2.
x= -5 +- 5
Answer:
x= -5 + 5
or x= -5 - 5
Beginning with the function y = sin x, which would have range from -1 to 1 and period of 2pi:
Vertical compression of 1/2 compresses the range from -1/2 to 1/2
Phase shift of pi/2 to the left
Horizontal stretch to a period of 4pi, as the crests are at -4pi, 0, 4pi
Vertical shift of 1 unit up moves the range to 1/2 to 3/2
So the first choice looks like a good answer.
