The population of two cities of 660000 people. If the population of the first city is equal to 32% of the population of the seco

Bogdan [553]

Answer:

population of 1st city =660,000

Step-by-step explanation:

Let the population of second city be x

given that

population of the first city is equal to 32% of the population of the second city

Therefore

population of 1st city = 32% of the population of the second city

32% of x = (32/100)*x

total population of two cities = x + (32/100)*x = (100x+32x)/100 = 132x/100

Also, population of two cities = 660000

thus,

132x/100 = 660000

=> 132x = 660000*100 = 66000000

=> x = 66000000/132 = 2,062,500

Thus, population of 2nd city is 2,062,500

population of 1st city = (32/100)*x = 32/100 * 2,062,500 = 660,000

The following are the ages (years) of 5 people in a room: 24 , 24 , 15 , 16 , 19 A person enters the room. The mean age of the 6

olga_2 [115]

Answer:

16 years old.

Step-by-step explanation:

(24+24+15+16+19+X) / 6 = 19

(98 + X) / 6 = 19

98 + X = (19)*(6)

98 + X = 114

X = 114-98

X = 16

Write the quadratic function in standard form.<br> f(x) = 6x^2 − x + 1

AlexFokin [52]

Answer:

The equation in standard form is:

$f(x)=6(x-\frac{1}{12})^2-\frac{23}{24}$

Step-by-step explanation:

Given function:

$f(x)=6x^2-x+1$

We need to convert this in standard form which is given by:

$f(x)=a(x-h)^2+k$

where $a$ represent co-efficient of leading term which is $x^2$

and $(h,k)$ is the vertex (minimum and maximum point) of the curve.

$h$ can be found out using formula $h=\frac{-b}{2a}$

$a=6\ and\ b=-1$

$h=\frac{-(-1)}{2(6)}=\frac{1}{12}$

We can find $k$ by finding $f(h)$ as $k=f(h)$ .

$k=f(\frac{1}{12})=6(\frac{1}{12})^2-\frac{1}{12}+1$

$k=(6\times \frac{1}{144})-\frac{1}{12}+1$

$k=\frac{1}{24}-\frac{1}{12}+1$

$k=\frac{1-2+24}{24}=\frac{23}{24}$

Thus the equation in standard form is:

$f(x)=6(x-\frac{1}{12})^2-\frac{23}{24}$
