Answer:
The correct answer is 1/49
Step-by-step explanation:
In order to find this, we first can eliminate the negative in the exponent by putting the whole this in the denominator.
(-7)^-2 = 1/(-7)^2
Now we can evaluate the denominator
1/(-7)^2 = 1/49
-9 duh
It says the first week look at the numbers and then the top row with numbers. the only one that matches up is -9
Perpendicular lines are a pair of lines that, when they intersect (cross over each other) they create 90 degree angles (also known as right angles, or a "perfect corner").
Keep this in mind for the next one: In math on graphs, lines go on forever.
So anyways, parallel lines are 2 lines that run DIRECTLY next to each other, so they never intersect.
Answer:
x = 5.57
Step-by-step explanation:
c² = a² + b² − 2ab cos C
x² = 10² + 6² − 2(10)(6) cos 29°
x = 5.57
Your answer and steps are correct.
