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

Answer:

±5sqrt(2) = x

Step-by-step explanation:

50 - x^2 = 0

Add x^2 to each side

50 - x^2 +x^2= 0+x^2

50 = x^2

Take the square root of each side

±sqrt(50) = sqrt(x^2)

±sqrt(25*2)) = x

±sqrt(25) sqrt(2) = x

±5sqrt(2) = x

The intensity of a radio signal from the radio station varies inversely as the square of the distance from the station. suppose
ICE Princess25 [194]
Let I represent intensity and and d the distance;
I\alpha  \frac{1}{ d^{2} }
When I=8000
8000=\frac{k}{4}
k=32000
I=\frac{32000}{d}
I=\frac{32000}{121}
I=265 units

<h3>What is Algebra?</h3>

Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.

An investor buys 400 shares of stock in a fund when the net asset value is $19.62 and the offer price is $19.84.

The investor sells these shares when the net asset value is $43.19 and the offer price is $43.56.

Then total cost price of the shares will be

→ 19.84 × 400 = $7936

The total selling price of the shares will be

→ 43.19 × 400 = $17,276

Then the profit is the difference between the total cost price of shares and the total selling price of the shares.

→ 17276 - 7936 = $ 9340
