Answer:

A. & A.

Step-by-step explanation:

sin(x) = cos(90-x)

Answer:

A. cos60° and A. cos30°  

Step-by-step explanation:

We know that is A and B are complementary, so

sinA = cosB

sin30° = cos60° and

sin60° = cos30°

So,

sin30°·sin60° = cos60°·cos30°

The product of sin30° and sin60° is same as the product of cos60° and cos30°.

Answer:

3.3 x 10⁻⁴

Step-by-step explanation:

Given expression:

           \frac{2.64 x 10^{-3} }{8.0 x 10^{0} }

 To solve this problem;

    10°   = 1

So;

             \frac{2.64 x 10^{-3} }{8.0}

    =  \frac{2.64}{8}  x 10⁻³

    = 0.33 x 10⁻³

    = 3.3 x 10⁻¹  x 10⁻³

     = 3.3 x 10⁻⁴

Line M passes through the points (5,1) and (8,6) while line n passes through the point (-4,3) and (-1,8) . Which statement accur
kirill [66]
M=(6-1)/(8-5)=5/3

y=5x/3+b, using (5,1)

1=25/3+b

b=-22/3

y=(5x-22)/3

...

m=(8-3)/(-1--4)=5/3...

y=5x/3+b, using (-1,8)

8=-5/3+b

b=29/3

y=(5x+29)/3

Since they have the same slope and difference y-intercepts they are parallel lines and will never intersect.
