Answer:
4/3
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
Using sum to product identities
cos x - cos y = - 2sin( )sin( ) = 2sin( )sin( )
cos x + cos y = 2cos( )cos( )
Note that
sin10° = sin(90 - 10)° = cos80°
Thus
← cancel 2 from numerator/ denominator
= ×
= tan45° × tan35° { tan45° = 1 ]
= 1 × tan35°
= tan35° ← as required
98000000 = 9.8 × 10⁷
So, Your Answer would be "False"
Hope this helps!
Line perpendicular to a given line is = 1/m
To find m, use m =y2-y1/x2-x1 formula
m = (8-(-3))/(-7-4)
m = 11/-11,
m = -1
Use y= mx+c to find equation of line
Plug in a pair of values,
-3= -1(4)+ c
c= 1
Thus, equation is:
y = -x+1
Equation of line perpendicular to this line is:
y= x+1

Step-by-step explanation:
A is excluded because in the second() x² should be negative
B is excluded because if you solve it -(-x² give you + x²
C is excluded because in the second() 2x and 1 should be negative
so D is right
