Calculer x si (x+1/2)^2= 4/9

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

Answer:

x=-\frac{7}{6}\\x=\frac{1}{6}

Step-by-step explanation:

The equation to solve is:

(x+\frac{1}{2})^2=\frac{4}{9}

To get rid of the "square", we need to take square root of both sides:

\sqrt{(x+\frac{1}{2})^2}=\sqrt{\frac{4}{9}}\\x+\frac{1}{2}=\frac{\sqrt{4}}{\sqrt{9}}

Then we use algebra to find the value(s) of x. Remember, when we take square root, we have to add up a "+-" (on the right side). Shown below:

x+\frac{1}{2}=+-\frac{\sqrt{4}}{\sqrt{9}}\\x+\frac{1}{2}=+-\frac{2}{3}\\x=\frac{2}{3}-\frac{1}{2}=\frac{1}{6}\\x=-\frac{2}{3}-\frac{1}{2}=-\frac{7}{6}

So these are 2 answers for x.

A radio station plays a total of 272 pop, rock, and hip-hop songs during a day. The number of pop songs is 3 times the number of
Norma-Jean [14]
Let the daily played number of pop songs be P, the number of rock songs be R and the number of hip-hop songs be H.

i) 
"A radio station plays a total of 272 pop, rock, and hip-hop songs during a day"

means that : P+R+H=272

ii) 
"The number of pop songs is 3 times the number of rock songs. "

so, P=3R

iii)
"The number of hip-hop songs is 32 more than the number of rock songs."

means: H=32+R

iv)

since both P and H can be written in terms of R, we have:

P+R+H=272

(3R)+R+(32+R)=272

3R+R+32+R=272

5R+32=272

5R=272-32=240

R=240/5=48


vi) 

thus: P=3R=3*48=144,    H=32+R= 32+48=80

Answer: 

48 Rock, 144 Pop and 80 Hip-hop
