What are the solution(s) to the quadratic equation 50 – x2 = 0?

Mathematics
1 answer:
Dmitrij [34]3 years ago
5 0

Answer:

x = ±5\sqrt{2}

Step-by-step explanation:

We have been given the quadratic equation;

50-x^{2}=0

The first step is to subtract 50 from both sides of the equation;

50-x^{2}-50=0-50

-x^{2}=-50

Multiplying both sides by -1 yields;

x^{2}=50

The final step is to obtain square roots on both sides;

\sqrt{x^{2} }=\sqrt{50}\\x=+/-\sqrt{50}

Therefore, x = ±5\sqrt{2}

How many words of five letters can be created that start with the letter T, contain 2 other consonats and end with 2 vowels? Not
Jet001 [13]

If we're only counting 5 vowels (A, E, I, O, U) and 20 consonants (everything else, minus T), then there are

\dbinom52=\dfrac{5!}{2!(5-2)!}=10

ways of picking the vowels, and

\dbinom{20}2=\dfrac{20!}{2!(20-2)!}=190

ways of picking the consonants.

We want the word to start with T, and we'll allow any arrangement of the other 4 letters, so that the total number of words is

4!\dbinom52\dbinom{20}2=\boxed{45,600}

Keep in mind that this means words like TRIES and TIRES are treated as different.

Barbara sells iced tea for $1.49 per bottle and water for $1.25 per bottle. She wrote an equation to find the number of bottles
g100num [7]

B. Barbara's equation did not consider the number of bottles of iced tea. She only put 1.49, which would mean she only sold one. Because we know she sells more then one, it should be 1.49(then a variable)
