2. A triangular pyramid begins with these coordinates:

1 answer:

3 0

The rule for the reflection is (x,y,z) → (-x,y,z) so P' = (1, 2, 0) for example.
Then the rule is (x,y,z) → (x + 2, y + 4, z - 3) so P'' = (3, 6, -3)

sergejj [24]

Answer:

Ben's rate is $\dfrac{1}{6}$ greater than Kate's rate.

Step-by-step explanation:

1. If it takes Ben 2 days to write reports, then his rate is $\dfrac{1}{2}$ of reports per day.

2. If it takes Kate 3 days to write reports, then her rate is $\dfrac{1}{3}$ of reports per day.

I need help in solving this problem (ASAP)

zhannawk [14.2K]

Answer:

The answer is y=24

Step-by-step explanation:

The triangle is a 30-60-90 triangle, which means that the it follows the respective ratio of x:x $\sqrt{3}$ :2x. Since we know that the 30 degree value is 8 $\sqrt{3}$ , we can establish that the 60 degree value is 8 $\sqrt{3}$ * $\sqrt{3}$ = 24.
