3rd one

there we have to find hypotenuse.

Inga [223]3 years ago

Answer:

+- 5/3

Step-by-step explanation:

When we construct a right triangle with legs with length 3 and 4. The hypoteneuse must 5. Since tan(x) = opp/adj = 4/3 and sec(x) = hyp/adj,

We get the answer to be 5/3. Now there is a +- there because if we use the unit circle, if we take the point (-3, -4), we get tan(x) = (-4/-3) = 4/3. However, the hypoteneuse for sec(x) is always positive so sec(x) = 5/-3 = -5/3.

That is why there are two solutions, one with the terminal arm in Q3 and one in Q1. But that's the explanation using the unit circle.

Choose the equation and the slope of the line that passes through (4, –2) and is parallel to the x-axis.
stiks02 [169]
If a line is parallel to the x -axis, that means the formula is going to be y=a, y is going to be the same for all points. 
We have the point where y coordinates = -2,
so the formula of the line  y = -2.

The perimeter of a rectangle is represented by the expression LaTeX: 2\left(3x+1\right)+2x2 ( 3 x + 1 ) + 2 x. Which statements
rewona [7]

Answer:

Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

L is the length of the triangle

W is the width

If the perimeter of a rectangle is represented by the expression 2\left(3x+1\right)+2

In order to know what wat each part represents, we will rewrite the given equation in the form 2(L+W).

Given

2\left(3x+1\right)+2x

Perimeter of a rectangle

2L+2W

Compare the given function with the perimeter to get L and W

L = 3x+1 \ and \ W = x

Hence the following statements explain correctly what each part of the expression represents

- One side of the rectangle measures x (the length)

- One side of the rectangle measures 3x + 1 (the width)

- 2 is the coefficient in each term that represents 2 lengths and 2 widths in a rectangle.
