how can you determine if a relation represented as an equation is a function? explain your reasoning​

Mathematics

oksano4ka [1.4K]3 years ago

Answer:

A relation is a function if x values never repeat, so every input will only have one output. If the function is graphed you can do the vertical line test, a relation passes if you can draw a vertical line anywhere on the graph and it only intersects with the relation once.

How can you show that a triangle has three congruent sides?
algol [13]
There are 4 rules for congruent triangles:

SSS-->This means side,side,side and to prove triangles are congruent with this rule, all the sides will be the same on both triangles.
SAS-->This means side,angle,side and to prove triangles are congruent, you must have 2 sides and an angle the same on both triangles, but the angle MUST be in between the 2 sides.
ASA-->This means angle, side, angle and to prove triangles are congruent with this rule, you must have two angles and a side the same, but the side MUST be in between the two angles.
RHS-->This means right angle, hypotenuse, side and to prove triangles are congruent with this rule, you must have a right angle in both triangles, and have an equal hypotenuse and side.

Hope this helps:)

32 ounces of water in a glass someone drink 55% how many ounces left in glass
borishaifa [10]
Hello!

Convert 55% to a decimal by dividing it by 100.

55 ÷ 100 = 0.55

Next, multiply the total amount of ounces of water by this decimal.

32 × 0.55 = 17.6

Finally, subtract the amount of ounces that person drank from the total number of ounces before they drank.

32 - 17.6 = 14.4

ANSWER:

14.4 ounces of water are left in the glass.

What is the length of the diagonal of the triangle?
Setler79 [48]

Answer:

21.25

Step-by-step explanation:

use the Pythagorean theorem, it is given that the shape is a rectangle so all opposite sides are congruent and all angles are right, since we know that the diagonal forms a right triangle we can use the pythagorean theorem

the Pythagorean theorm is a^2+b^2=c^2 where a and b are the legs (in this case the side of the triangle) and c is the hypotenuse which is the longest side in a right triangle

17^2+12.75^2=x^2

x^2=7225/16

now take the square root of both sides and you get -21.25 and 21.25

distance CAN NOT be negative so -21.25 isn't an option
