Lines c and d are parallel lines cut by transversal p.
bearhunter [10]
First, let's start off, let us define what are corresponding angles. When a transversal, which is a line that passes through two parallel lines, then the angles in the same corners are congruent.

Using this definition, the angles ∠2 is congruent to ∠6.

If you flipped a fair coin 18 times, about how many times would you expect heads to appear? HELP ME PLEASE!!!!!!!
Andrei [34K]

Answer:

9 or 3.8x10^-6

Step-by-step explanation:

By flipping a coin you'd look at how many times a head could appear (1/2) and multiply that by the 18 times.

Another explanation:

I'm not sure on this but would you raise 1/2 to the 18th power?

A baseball is thrown in a parabolic arc. It's position above the ground at a given point in time can be represented by the quadr
SCORPION-xisa [38]

Answer:

The baseball reached 9 feet high above the ground

Step-by-step explanation:

The given quadratic function representing the position of the baseball above ground is p(t) = 1/2·g·t² + v₀·t + p₀

Where;

t ≥ 0

g = -32 ft./sec²

v₀ = The initial velocity

p₀ = The initial position

Given that when the ball is thrown, we have;

The initial, straight up, velocity, v₀ = 16 ft./sec

The initial position, p₀ = 5 ft.

Substituting the above values in the quadratic function representing the position of the baseball above ground, we have;

p(t) = 1/2·(-32)·t² + 16·t + 5 = 16·t - 16·t² + 5

At the maximum point, the rate of change of the height with time = 0, therefore;

dp(t)/dt = 0 = d(16·t - 16·t² + 5)/dt = 16 - 32·t

16 - 32·t = 0

16 = 32·t

t = 16/32 = 0.5 seconds

Therefore, the time takes to reach the maximum height = 0.5 seconds

The height (maximum) reached in 0.5 seconds is given as follows;

h(t) = 16·t - 16·t² + 5, from which we have;

h(0.5) = 16 × 0.5 - 16 × (0.5)² + 5 = 9

Therefore, the height baseball reached = 9 ft. above ground

NEED HELP IN NEED THE ANSWER BY TO NIGHT PLE.
guapka [62]

Answer:

Step-by-step explanation:

1 sandwich is 6.25 (because 31.25/5)

2 sandwiches is 12.5

3 sandwiches are 18.75

4 sandwiches are 25

5 sandwiches are 31.25

6 sandwiches are 37.5

Amy - 8s + 12

8(6.25) +12 = 62

Amy paid $62.

Bob - 8(s + 2)

8(6.25 + 2) = 66

Bob pays $66.

Cathy - 4(2s + 3)

4(2 x 6.25 + 3) = 62

Cathy paid $62.
