The largest angle of a triangle is 60° larger than the smallest angle. the middle angle is triple the measure of the smallest an

Alex787 [66]

Total degree in triangle is 180.
so, 180= x + 3x + (x+60)
180 = 5x +60
5x = 180-60
5x = 120
x = 24
Largest angle is 84
Middle angle is 72
Smallest angle is 24

Find a number that is between2/9and3/11

SVETLANKA909090 [29]

$\text {Between } \dfrac{2}{9} \text { and } \dfrac{3}{11}$

Change the denominators to be the same:
$\text {Between } \dfrac{2 \times 11}{9 \times 11} \text { and } \dfrac{3 \times 9}{11 \times 9}$

$\text {Between } \dfrac{22}{99} \text { and } \dfrac{27}{99}$

$\text {Possible answers are } \dfrac{23}{99} \ , \dfrac{24}{99} \ , \dfrac{25}{99} \text { and } \dfrac{26}{99}$

K here’s another one please help

Answer:

Both the relations are functions, the correct answer is a.

Step-by-step explanation:

In order to solve this problem we will first find the inverse relation as shown below:

$y = 3x^2 + 5\\x = 3y^2 + 5\\3y^2 = x - 5\\y^2 = \frac{x - 5}{3}\\y = \sqrt{\frac{x - 5}{3}} = \frac{\sqrt{x - 5}}{\sqrt{3}}\\y = \frac{\sqrt{x - 5}\sqrt{3}}{\sqrt{3}\sqrt{3}} = \frac{\sqrt{3x - 15}}{3}$

Functions are relations between two groups of numbers, for which the input must generate only one output. Using this definition we can classify both the relation and its inverse as a function, therefore the correct answer is a.
