Answer:
465.988 mph
Step-by-step explanation:
The two speed vectors form two sides of a triangle. Their included angle is 45°, so the law of cosines can be used to find the resultant magnitude x.
x^2 = 500^2 +50^2 -2·500·50·cos(45°) ≈ 217,144.66
x ≈ √217,144.66 ≈ 465.988 . . . . miles per hour
_____
You may find you need to round the answer to the nearest whole number.
Answer:
because there is no cents, so its a whole number, and it will help if u put the answer choices
Step-by-step explanation:
Answer: 26%
Step-by-step explanation:
Percent change: (New-Old)/Old times 100; (11.34-9)/9=0.26x100=26
Hundreds period, since the 6 is in the ones, 8 is in the tens, and 4 is in the hundreds.
Step 1 3(2x+7)-4=53-3x given
step 2 6x+21-4=53-3x expanding
step 3 6x+17=53-3x adding (21-4)
step 4 9x+17=53 adding 3x to both parts
step 5 9x=36 subtracting 17 from both sides
step 6 x=4 divding by 9
