2 x 5
2+2+2+2+2= 10
2 x 5= 10
Answer:
(5,3)
Step-by-step explanation:
Look for the coordinates of the point of intersection where the 2 graphs cross. This gives the solution.
In this case, they cross at (5,3) and they intersect at only one location (i.e there is only 1 solution)
Answer:
h = 17.65 m
Step-by-step explanation:
The given equation gives the speed at impact :
h is height form where the object is dropped
Put v = 18.6 m/s in the above equation.
So, the object must be dropped from a height of 17.65 m.
Answer:
bro i do not know how to do that stuff im only in Middle school my guy
Step-by-step explanation:
I don't know
Sin x - 1 = 0
sin x = 1
x 1 = π / 2
2 sin² x + 5 sin x + 2 = 0
Substitution: u = sin x
2 u² - 5 u + 2 = 0
2 u² - 4 u - u + 2 = 0
2 u ( u - 2 ) - ( u - 2 ) = 0
( u - 2 ) ( 2 u - 1 ) = 0
( sin x - 2 ) ( 2 sin x - 1 ) = 0
sin x - 2 = 0
sin x = 2 ( does not have solution )
2 sin x - 1 = 0
2 sin x = 1
sin x = 1/2
x 2 = π / 6 , x 3 = 5 π / 6
Answer:
x = π / 6 , π / 2 and 5 π / 6.
