hello mate

This is neha to help you here

answer

since its a right traingle we can use trignometric ratos to solve this problem

<A= 30°

AB=4CM

AB IS THE HYPTONUESE OF THE TRAINGLE = 4CM

AND BC IS THE OPPOSITE SIDE OF ANGLE 30°

SO,

SIN30° =\frac{OPPOSITE SIDE}{HYPOTENUSE}

\frac{1}{2} = \frac{x}{4} \\\\CROSS MULTIPLYING\\\\2X= 4\\\\X= \frac{4}{2}\\ \\X= 2CM

SO BC IS 2 CM LONGER

Nitella [24]

Answer:

Each person should chip in $0.83

Step-by-step explanation:

Total cost =3000km(66/100)(1.20/L)

                   =45.46 × 1.20

                     =$54.55

Cost per person = ($54.55/66)

                            =$0.83 person

Each person should chip in $0.83

The following table gives a partial set of values of a polynomial function. x −2 −1 0 1 2 3 g(x) 14 2 0 4 6 −2 Between which two
motikmotik

From -1 to 0, the function goes decreases, and from 0 to 1 the function goes increases. Then we will have the minimum between -1 and 1.

<h3>Between which two values would a relative minimum most likely occur?</h3>

Here we have the table:

  • x: -2, -1, 0, 1, 2, 3
  • g(x): 14, 2, 0, 4, 6, -2

You can see that:

g(-1) = 2

g(0) = 0

So the function goes downwards from x = -1 to x = 0.

g(1) = 4

So the function goes upwards between 0 and 4.

Then, from -1 to 0, the function goes decreases, and from 0 to 1 the function goes increases. Then we will have the minimum between -1 and 1.
