Answer:

A.105°

Step-by-step explanation:

Angle at W and V are equal and the angles at T and U are also equal

Hence taking angles at T and U...so as to calculate the value of x

5x + 15 = 3x + 21

5x - 3x = 21 - 15

2x = 6.....hence, x = 3

Then for the angle of VXU;

All angles in a triangle add up to 180°

15(3) + 3(3) + 21 = 75°...then subtract from 180°..so as to obtain angle at VXU

180 - 75 = 105°

Which of the following illustrates the truth value of the following conditional?

The truth table for implication of the equations is F F ⇒ T

<h3>What is a truth table?</h3>

A truth table is a mathematical logic table that shows the truth values of different logic statements combined by a given logic rule.

Analysis:

P: 7 +1 is not equal to 0 making P to be false(F)

q: 2+2 is not equal to 5 making q to be false(F)

so for conditional or implication, F F⇒ T

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.

PLEASE HELP! WILL MARK BRAINLIEST! 15 POINTS! The median of the list n, n + 2, n+3, n+5, n+7, n+8, n+11, n+14, n+16, n+19 is 20.

pav-90 [236]

Answer:

Step-by-step explanation:

n, n + 2, n+3, n+5, n+7, n+8, n+11, n+14, n+16, n+19

The median is the middle number

There are 10 numbers so the middle is between the 5th and 6th number

n, n + 2, n+3, n+5, n+7, n+8, n+11, n+14, n+16, n+19

We average those two numbers

(n+7 + n+8)/2 = 20

(2n+15) / 2 = 20

Multiply by 2

2n+15 = 40

Subtract 15

2n = 25

Divide by 2

n = 25/2

n = 12.5

We want to find the mean, which is add up all the numbers and divide by the number of numbers

(n+ n + 2+ n+3+ n+5+ n+7+ n+8+ n+11+ n+14+ n+16+ n+19)/10

(10n+85)/ 10

n+ 8.5

12.5 + 8.5 = 21
