<u>Answer:</u>
The plane's resultant vector is 890.3 miles, at an angle of 59.5° west of north.
<u>Step-by-step explanation:</u>
• To find the magnitude of the resultant vector, we have to use Pythagoras's theorem:

where:
a ⇒ hypotenuse (= resultant vector = ? mi)
b, c ⇒ the two other sides of the right-angled triangle (= 452 mil North, 767 mi West).
Using the formula:
resultant² = 
⇒ resultant = 
⇒ resultant = 890.3 mi
• To find the direction, we can find the angle (labeled <em>x</em> in diagram) that the resultant makes with the north direction:

⇒ 
⇒ 
∴ The plane's resultant vector is 890.3 miles, at an angle of 59.5° west of north .
Answer:
201 mobile phones
Step-by-step explanation:
July: 74 mobile phones
August: 74 - 8 = 66 mobile phones
September: 66 - 5 = 61 mobile phones
74 + 66 + 61 = 201 mobile phones
Hope this helps!
Answer is C.
F(x) = 3 * (1.7)^x
Ok so I'll show u how to do number 7
So 12 and one third basically equals 12+(1/3)
Now in order to add this to another fraction, we need to make the mixed numbers in improper fractions
So 12 and (1/3)=(36/3)+(1/3)
And 9 and (2/3)=(27/3)+(2/3)
Ok so the first number (or 12 and (1/3)) basically equals (37/3)
The second number (or 9 and (2/3)) equals (29/3)
Now that we have the two numbers with common denominators, we can do the math.
(37/3)-(29/3) is the same as (37-29)/3
So simplifying would be
(8/3) or 2 and (2/3)
