Answer:
1/2
Step-by-step explanation:
cos(θ) = √(1 -sin(θ)²) = √(1 -3/4) = √(1/4)
cos(θ) = 1/2
Answer:
The equation of the line would be y = 1/5x + 8
Step-by-step explanation:
Since the slope of k is -5, the slope of j has to be 1/5. This is because perpendicular lines have opposite and reciprocal slopes.
Now we can use the slope and the point in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 9 = 1/5(x - 5)
y - 9 = 1/5x - 1
y = 1/5x + 8

Answer:
a)2/7
b)41/48
<em />
<em>Step-by-step explanation:</em>
<u>-Question A-</u>
1) Rephrase the problem to look like this:
3/7*28/15*5/14 <-- when dividing fractions you actually multiply by the reciprocal (opposite)
2) Multiply across the above phrase:
420/1470
3) Simplify your fraction:
2/7
There is nothing else to be done with 2/7 and thus it is your final answer.
<u></u>
<u>-Question B-</u>
1) Get the denominator of all 3 fractions to the same Least Common Denominator (48):
42/48 + 3/48 - 4/48
2) Do the arithmetic in the phrase above:
41/48
41/48 cannot be simplified and thus is your final answer
