Which set of ordered pairs does not represent a function? \{(5, -9), (6, -6), (-3, 8), (9, -6)\}{(5,−9),(6,−6),(−3,8),(9,−6)} \{

Nady [450]

Answer:

$\{(-6, -4), (4, -8), (-6, 9), (1, -3)\}$

Step-by-step explanation:

Given

$\{(5, -9), (6, -6), (-3, 8), (9, -6)\}$

$\{(-6, -4), (4, -8), (-6, 9), (1, -3)\}$

$\{(1, -1), (-5, 7), (4, -9), (-9, 7)\}$

$\{(8, -9), (-3, -6), (-4, 4), (1, -5)\}$

Required

Which is not a function

An ordered pair is represented as:

$\{(x_1,y_1),(x_2,y_2),(x_3,y_3),..........,(x_n,y_n)\}$

However, for the ordered pair to be a function; all the x values must be unique (i.e. not repeated)

From options (a) to (d), option (b) has -6 repeated twice. Hence, it is not a function.

Technical improvement of a factory enabled it to produce 165 parts more in February than in January. In the two-month period, th

Romashka-Z-Leto [24]

X + x + 165 = 1315
2x + 165 = 1315
subtract 165 from both sides
2x = 1150
divide both sides by 2
x = 575
January 575
February 575 + 165 = 740

A paperweight is shaped like a triangular pyramid. The base is an equilateral triangle. Find the surface area of the paperweight

stich3 [128]

Answer:

The surface area of the paperweight is $SA=8.3\ in^2$

Step-by-step explanation:

we know that

The surface area of the triangular prism is equal to the area of its triangular base plus the area of its three triangular lateral faces

Find the area of its triangular base

$SA=\frac{1}{2}(2)(1.7)$

$SA=1.7\ in^2$

Find the area of its three triangular lateral faces

$SA=3[\frac{1}{2}(2)(2.2)]$

$SA=6.6\ in^2$

Adds the areas

$SA=1.7+6.6$

$SA=8.3\ in^2$
