Taking the Dot Product = 0 shows perpendicular or orthagonal vectors.
Then 2ax6 -axa +32x(-1) = 0
a^2 -12A +32 = 0
(a-8)(a-4) = 0
a = 4,8
The first thing you should know is the following conversion:
1h = 60min
What you can do to solve the problem is the use of a rule of three:
60 ---> 3.8
165 ---> x
Clearing the value of x we have:
x = (165/60) * (3.8) = 10.45
x = 10.45 mi
answer
she can walk 10.45 mi in 2 hours 45 minutes
Answer:
Step-by-step explanation:
Use the formula for calculate the distance between two points:
Calculate the distance AB. Substitute the coordinates into the formula. Then:
Calculate the distance A'B'. Substitute the coordinates into the formula. Then:
As you can see, the distance A'B' is the distance AB multiplied by 1/2. Therefore, this is the scale factor.
