Answer:
no
Step-by-step explanation:
they are different
a.b = |a|.|b|cos x
9x135 = 1,215
10x135 = 1,350
11x135 = 1,485
Therefore, your answer would be 10.
Answer:
ab=16
ca=4
4a=32
Step-by-step explanation:
a*b=8*2=16
c*a=1/2*8=4
4*a=4*8=32

Answer:
1) A 2) B 3) C 4) C 5) A 6) B
Step-by-step explanation:
1) Slope is calculated by the change in y over the change in x thus (5-3)/(2-(-1)) = 2/3
2) Since there is no change in y, there is no slope.
3) The change in x is given which is 10-2 so the change in y is y2-3. For the slope to be 3/4 y must equal 6. Therefore y2 is 9.
4) Cosine is adjacent over hypotenuse and Tangent is opposite over adjacent. Given 3/5 as A/H you can construct a right triangle with the adjacent as 3 and hypotenuse as 5. The Pythagorean theorem says the adjacent squared plus the opposite squared is equal to the hypotenuse squared.
3^2 + O^2 = 5^2
O=4
Therefore TanP is 4/3
5) Pythagorean theorem again.
Therefore your hypotenuse is equal to 
6) Csc is the inverse of the Sin function. So it becomes 5/4.
