Hey !!!
sinx = 3/5 ( given )
We know a formula of cos2x = ( 1 - 2sin²x)
putting the value of sinx on value of cos2x = ( 1 - 2sin²x)
hence,
we get
cos2x = ( 1 - 2sin²x )
=> [1 - 2 × ( 3/5 )² ]
=> [ 1 - 2 × 9 /25 )
=> [ 25 - 18 /25 ]
=> 7/25 Answer ✔
Answer:
45
Step-by-step explanation: 15x3
Answer: ( 0, 2 )
Step-by-step explanation:
You have to put coordinates of each graph on these equations y = -x + 2 and y = (1/2)x + 2. If putting coordinates satisfies both equations, then that coordinate will be the solution.
For example, let's put (0, 2) to equations.
y = -x + 2
2 = -0 + 2
2 = 2, true
y = (1/2)x + 2
2 = (1/2) × 0 + 2
2 = 2, true
So, ( 0, 2 ) is the solution.

The formula for slope is:
slope=y2-y1/x2-x1 where (x1,y1) and (x2,y2) are points on the line
In this situation we know the x values of two points, and we know the slope, so we can solve for the missing y values.
slope=-7
(11,y1) (16,y2)
Now lets plug in the information into the formula.
slope=y2-y1/x2-x1
-7=y2-y1/16-11
-7=y2-y1/5
multiply both sides by 5
-35ft=y2-y1
distances cannot be negative so lets change -35ft to a positive number
35ft=y2-y1
The vertical distance between the two points is 35feet
Answer= A) 35ft
