In △ABC, angle C is a right angle and BC > AC. Select all the statements that are true.

Alexus [3.1K]

△ABC right angle C, leg BC > leg AC. So angle A > angle B.

a=BC, b=AC, c=AB

a > b

sin A= cos B = a/c

sin B = cos A = b/c

a = c sin A = c cos B

b = c sin B = c cos A

a > b

c sin A > c sin B

sin A > sin B

c cos B > c cos A

cos B > cos A

Answer: B, E

What’s the answer to this question ?

HACTEHA [7]

Answer:

Step-by-step explanation:

Line pases through (6, 0) and (0, -6)

Slope = (0 - (-6))/(6 - 0) = 6/6 = 1

so y = 1*(x - 6) = x - 6

or x - y = 6

or 4x - 4y = 24

That is C

The net of a triangle prism is shown.Use the ruler provided to measure the dimensions of the net to the nearest half centimeter.

nikklg [1K]

Answer:

<h2>The total surface area of the figure is 516 square units.</h2>

Step-by-step explanation:

The net of the triangular prims is attached.

Remember, the total surface area refers to the area of each face of the volumetric figure. In this case we have three equal rectangles and two equal triangles.

<h3>Area of the rectangles.</h3>

$A_{1}=3(10 \times 14)=3(140)=420 \ u^{2}$

Remember that the area of a rectangle is just the product of its width and height.

<h3>Area of the triangles.</h3>

$A_{2}=2(\frac{1}{2} \times 12 \times 8 )=96 \ u^{2}$

The total surface area is given by the sum of all these areas:

$S=420 + 96 = 516 \ u^{2}$

Therefore, the total surface area of the figure is 516 square units.

Which relation is a function? {(–4, –6), (–3, –2), (1, –2), (1, 0)} {(–2, –12), (–2, 0), (–2, 4), (–2, 11)} {(0,1), (0, 2), (1,

Blababa [14]

Answer:

$\{(8, 1), (4, 1), (0,1), (-15, 1)\}$

Step-by-step explanation:

Given

$\{(-4, -6), (-3, -2), (1, -2), (1, 0)\}$

$\{(-2, -12), (-2, 0), (-2, 4), (-2, 11)\}$

$\{(0,1), (0, 2), (1, 2), (1, 3)\}$

$\{(8, 1), (4, 1), (0,1), (-15, 1)\}$

Required

Determine which is a function

A relation is divided into 2; (x,y)

Where x represents the range and y stands for the domain

For a relation to be a function, the x column must be unique; in other words, there must be only one occurrence of x

Testing each of the given options

A. $\{(-4, -6), (-3, -2), (1, -2), (1, 0)\}$

Start by splitting the relation into x and y columns

$(x,y)$

$(-4, -6)$

$(-3, -2)$

$(1, -2)$

$(1, 0)$

Notice that the third and fourth relation has the same x value of 1;

<em>Hence, this is not a function</em>

B. $\{(-2, -12), (-2, 0), (-2, 4), (-2, 11)\}$

Start by splitting the relation into x and y columns

$(x,y)$

$(-2, -12)$

$(-2, 0)$

$(-2, 4)$

$(-2, 11)$

Notice that all relations has the same x value of -2;

<em>Hence, this is also not a function</em>

C. $\{(0,1), (0, 2), (1, 2), (1, 3)\}$

Start by splitting the relation into x and y columns

$(x,y)$

$(0, 1)$

$(0, 2)$

$(1, 2)$

$(1, 3)$

Notice that the first and second relation has the same x value of 0 and the third and fourth relation has the same x value of 1;

<em>Hence, this is also not a function</em>

D. $\{(8, 1), (4, 1), (0,1), (-15, 1)\}$

Start by splitting the relation into x and y columns

$(x,y)$

$(8, 1)$

$(4, 1)$

$(0, 1)$

$(-15, 1)$

Notice that relation has the unique x values of 8, 4, 0 and -15

<em>Hence, this relation is a function</em>
