d
Step-by-step explanation:
the angle is less than 90 degrees
if you add 500+30+4, it will equal 534 . standard form means an easier way of writing down very large or very small numbers. an esier way to write 500+30+4 would be 534. also can be called standard form which has the same value.
in standard form:
500+30+4 is

Hello Anna,
(a)
1.25 per ticket
? number of rides (x)
43.75 total cost (y)
Admission (z)
(b) Linear Equation - 1.25x + z = y
(c) Well you need to calculate the totaly number of rides that person took and add that to the admission cost.
Answer: C) (9x^4-x^3-x)/5
<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 .
