Answer:
New distance = 2do
Step-by-step explanation:
The distance equation :
Distance = speed * time
If speed is doubled ; time stays the same
If speed is doubled,; new speed becomes
Doubled speed = 2* speed
Time remains the same ;
Hence,
New distance becomes : 2 * speed * time
Original dista, Speed * distance
New distance, dn = 2*do = 2do
To do this you need to put it in function form.
Here's the work
2y-3x = 8
2y-3x = 8
+3x +3x
2y = 3x+8
/2. /2
y = 3/2x + 8
To find perpendicular you multiply the slope the the opposite reciprocal.
y = -2/3x + 8
Then the +8 doesn't really matter now
Slope that is perpendicular is -2/3x
They can stand 9 different ways
Let's find all the prime numbers.
1,3,5,7,9,11,13,15,17,19
They are not divisible by 2.
Put that into a fraction, where the amount of numbers is the numerator and the total amount of numbers is the denominator.
10/20
That is half of 20.
So, 50% of the 20 first natural numbers are prime.
I hope this helps!
