The value of the function

uysha [10]

Substitute the value of x into the function;

f(0.25)=1/3(-5(0.25))
f(0.25)=1/3(-5(1/4))
f(1/4)=1/3(-5/4)
f(1/4)=-5/12

Therefore, the function would be at -5/12 when x=1/4

Hope I helped :)

Svetlana's hair is 3 cm long. Her hair

NemiM [27]

Required inequality is 1.5x + 3 < 18 and solution is x < 10, that is number of months svetlana can allow her hair to grow must be less than 10 so that her hair length will be less that 18 cm

Solution:

Given that

Svetlana's hair is 3 cm long.

Her hair grows 1.5 cm per month

Need to write an inequality to determine the number of months Svetlana can allow her hair to grow.

Let assume number of months Svetlana can allow her hair to grow be represented by variable "x"

Length of hair grows in one month = 1.5 cm

So Length of hair grows in "x" months = $\text { Length of hair grows in one month } \times x=1.5 \times x=1.5 x$

As Svetlana wanted her hair to be less than 18 cm long

So Length of hair grows in "x" months plus current length of hair must be less than 18 cm

=> 1.5x + 3 < 18

On solving the above inequality for "x" we get ,

1.5x < 18 – 3

=> 1.5x < 15

=> $x < \frac{15}{1.5}$

=> x < 10

Thus required inequality is 1.5x + 3 < 18

Number of months sultana can allow her hair to grow must be less than 10 so that her hair length will be less that 18 cm.

The U.S. public debt as of October 2010 was $9.06 × 1012. What was the average U.S. public debt per American if the population i

Fofino [41]

Answer-

The average U.S. public debt per American is approximately $29,400

Solution-

Given in the question,

U.S public debt as of October 2010 = $9.06×10¹²

Population of U.S in 2010 = 3.08×10⁸

We have to calculate the average U.S. public debt per American,

$\text{Average debt per American}=\frac{\text{Total debt}}{\text{Population}}\\\\=\frac{9.06\times 10^{12}}{3.08\times 10^8}\\\\=2.9415\times 10^{(12-8)}\\\\=2.9415\times 10^4 \approx 2.94\times 10^4=29,400$

Therefore, the average U.S. public debt per American is $29,400 (after rounding off)
