The boat turns into a car? and also the math doesn’t make sense, unless the car/boat is going 325 miles in 25 minutes...
X*26=180 subtract 26 from 180 then you will find x.
Answer:
145 degrees (c)
Step-by-step explanation:
Take your smallest interior angle (35 degrees) & subtract it from 180.
That will give you your largest exterior angle.
180 - 35 = 145 degrees
Hope this helped. :)
18. s = 5r^2 + 7......making r the subject
s - 7 = 5r^2
(s - 7) / 5 = r^2...by taking the sqrt of both sides, it eliminates the ^2
( sqrt (s-7)/5) = r
19. h = ut - 1/2gt^2....u = 100, t = 1 4/5(or 9/5)...g = 6.4
h = (100)(9/5) - 1/2(6.4)(9/5^2)
h = 180 - 1/2(6.4)(3.24)
h = 180 - 3.2(3.24)
h = 180 - 10.368
h = 169.632 or 169 79/125
20. sorry..do not know this one
Answer:
Step-by-step explanation:
The magnitude of a vector v = ai + bk is
In this problem, we have that:
Find a vector of magnitude 3 in the direction of v=4i-3k:
The first step is finding the unit vector of v, 
.
So
Magnitude 3, same direction.
We multiply the unit vector by +3, since it is in the same direction. If it was in the opposite direction, we would have multiplied by -3.
The answer is:
