Answer:

45 minutes

Step-by-step explanation:

If it is one and a half it would be a whole so 30 but the half, is half of 30, so 15. 30+ 15= 45

2. For the graph, find AB to the nearest tenth<br> y<br> 8<br> А<br> 6<br> B
zheka24 [161]

Answer:

10.8

Step-by-step explanation:

AB can be calculated using the formula d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

The coordinates of A are when x = -2, y = -2

At B, x = 8, y = -6

Let,

A(-2, -2) = (x_1, y_1)

B(8, -6) = (x_2, y_2)

Plug the values into the formula.

AB = \sqrt{(8 - (-2))^2 + (-6 -(-2))^2}

AB = \sqrt{(8 + 2)^2 + (-6 + 2)^2}

AB = \sqrt{(10)^2 + (-4)^2}

AB = \sqrt{100 + 16}

AB = \sqrt{116} = 10.8 nearest tenth

Two arrows are launched at the same time with the same speed. arrow a at an angle greater than 45 degrees, and arrow b at an ang
valentina_108 [34]
Let V = the launch velocity
Let θ =  the launch angle
Let d =  the horizontal distance traveled

Ignore air resistance.

The horizontal component of velocity is
u = V cos θ
The time of flight is
t = d/(V cosθ) = (d/V) secθ

Create a table of θ versus t as shown below.
   θ    t/(d/V)
----   ----------
45    1.4142
40    1.3054
35    1.2208
30    1.1547

The graph shows that as the launch angle decreases below 45°, the time of flight decreases.
Therefore arrow b (θ < 45°) arrives first.

Answer: Arrow b arrives first.

Please answer !! what is the factorization of the trinomial below ?
Alex_Xolod [135]
Since we always want to have an a which equals 1 so then we don't have to do AC method, a longer process, we're going to want to take out the -1.

-1(x^2 - x - 42)

Then, we want to know what two number multiply to equal c (-42 here) and add up to equal b (-1 here). Those two numbers would be -7 and 6 since -7(6) = -42 and -7 + 6= -1.

So then from here we can just plop these numbers into (x+ __).

1(x-7)(x+6)

This is your final answer, A.
