What are the solution(s) to the quadratic equation 50 – x2 = 0? x = ±2

Mathematics
1 answer:
Firdavs [7]3 years ago
4 0

Answer:

  x = ±5√2

Step-by-step explanation:

Add x^2 to both sides.

  50 = x^2

Take the square root.

  ±√50 = x

  x = ±5√2 . . . . . simplified roots

The solutions to the quadratic are x = -5√2 and x = 5√2.

Simplify. Rewrite the expression in the form 5^n<br>(5^3)^2=<br>​
Temka [501]

Answer:

5^12

Step-by-step explanation:

index notation rules states that when there is a power inside AND outside the brackets, they shall multiply together. hence, we will multiply 3 and 2 so we will get 6 and thus the answer will be 5^6. Sike, that's not the answer, we forgot to multiply 5 with that power too... so we will get 25^6 because same power (outside brackey) will affect everything inside...

now after we got 25^6, we need to simplify it to get 5^n ....

so as we know 5^2 is 25, we can do this,

(5^2)^6 so we will multiply the powers to get

5^12 which is your answer :)

pls mark this as brainliestttt

Find the cost of 20 grams of lead at 60$ per kilogram
ASHA 777 [7]

Answer:

$1.20

Step-by-step explanation:

Ratio:

Grams : Kilograms

1 : .001

Multiply both sides by 20 to convert grams to kilograms:

Grams : Kilograms

1 : .001

x20 x20

20 : .02

This means that 20 grams of lead = .02 kilograms of lead

Price:

Cost : Kilogram

$60 : 1

Multiply both sides by .02 to find the price of the lead:

Cost : Kilogram

$60 : 1

x.02  x.02

$1.20 : .02

Therefore, .02 kg of lead costs $1.20.
