Answer:
<-8.60, -12.29>
Step-by-step explanation:
Pictuas shown in the attached image to represent the direction 35 west of south of the vector velocity and understand which trig function to use for its components. See the actual vector velocity as the hypotenuse of a right angle triangle.
The vertical component would be pointing down, and its magnitude would result from the use of the cosine of the angle (since it involves the adjacent side to the angle):
15 * cos (35) = 12.29
the horizontal component is pointing left, and its magnitude would be the result of the use of the sine of the angle (it involves the opposite side to the angle):
15 * (sin*35) = 8.60.
Using the fact that the components are pointing down and pointing left, we need to include a negative sign to both.
Therefore the component form of the vector is: <-8.60, -12.29>
Answer:
A
Step-by-step explanation:
we can find using the trigonometric formulas
we can find y by using cosine.
cos = adj / hyp
cos 60 = y / 10
y = 10 cos 60
y = 5
now we can use the Pythagorean theorem since we have the base and hyp
a² + b² = c²
5² + b² = 10²
25 + b² = 100
b² = 75
b = 5√3
Answer:
Step-by-step explanation:
2 fractions with the numerator and different denominators can be compared when you find the lowest common denominators (LCD. For example 1/2 and 1/3 have the same numerator, but the denominators are not so you have to find the LCD. The LCD, in this case, is 6, so the fractions would be 3/6 and 2/6 and now if you compare you can tell that 3/6 is greater than 2/6 so 1/2 is greater than 1/3.
Answer:
20 years approx
Step-by-step explanation:
Step one:
given data
Principal= $1000
rate= 6%
Final amount A= $3300
Required
Time t
Step two:
the expression for the compound interest is given data
A= P(1+r)^t
t = ln(A/P) / r
substitute
t= ln(3300/1000)/0.06
t= ln3.3/0.06
t= 1.193/0.06
t=19.88 years
t= 20 years approx
