Distance formula: SR (A^2+B^2)
SR [(2+9i)^2 + (2-4i)^2] =
SR [4 + 18i + 81i^2 + 4 - 8i + 16i^2] =
SR [8 + 10i + 97i^2]

suppose that a certain basketball athlete earned $23,000,000 to play 80 games, each last 48 min. how much did the athlete earn p
Anit [1.1K]
He earns 23 000 000 per 80 games for 48min
Per game he earns
23000000 \div 8 0 = 782500
If he earns 782 500 per game he earns 5 989,5833 per minute

782500 \div 48 = 5989.5833
If he played 2/3 of the time he played 32min which means he earned...

782500 \div 32 = 24453.125
So he trained 35hours for a 48min match
Together that is 35.8hours

But I dont think this really matters here you just have to multiply 24453.125 with 60

And you get his hourly salary which is 1 467 187.5

How can I solve number 4 and 6?
SOVA2 [1]
4. Here you would use the Pythagorean Theorem. a² + b² = c²
In this case a and b are the same, so : a² + a² = c² would also work.
a = 5√2 so: (5√2)² + (5√2)² = c²
Do you know where to go from here?

How many flowers, spaced every 6 inches, are needed to surround a circular garden with a 10 foot radius?
Stolb23 [73]

To solve this problem you must apply the proccedure shown below:

1. You must calculate the perimeter of the circle:

The radius of the circle in inches is:

radius=\frac{(10ft)(12in)}{1ft}=120in

P=2\pi(radius)\\  P=2\pi(120in)\\ P=753.98in

2. Now, you must divide the perimeter by the space between each flower to find the number of flowers needed, which you can call x:

x=\frac{753.98in}{6in}=125.6=126

The answer is: 126 flowers.
