Answer:

2.4 *103 = 247.2

1.5*103 = 154.5

3.6*106 = 381.6

3.9*106 = 413.4

3.6*109 = 392.4

3.9*109 = 425.1

Step-by-step explanation:

2.4 * 103

we firstly count decimal numbers

in the calculation

only 2.4 has a decimal and only one number after the point

so we keep it aside making

2.4 = 24 1 dp (decimal place)

back to the calculation

1 0 3

* 2 4

----------

4 1 2

2 0 6

-------------

2 4 7 2

-------------

don't forget we still have a dp !

so we place the point 1 step backward

2472 to 1dp =

247.2

with this we can solve orders

Find the dependent value
DiKsa [7]

Answer:

Y = 27

Step-by-step explanation:

In the equation (y = 12 + 5x) the X is the independent value. When you replace this by 3 you will multiply 3*5 which will give you 15 and then you will want to add 12 as that is your y intercept. Giving the value of your Y a 27, or the point would be (3,27)

Find a polynomial of the form
Sloan [31]

Answer:

f(x)=-\frac{1}{4}x^3-\frac{1}{6}x^2+\frac{65}{12}x-3

Step-by-step explanation:

We are given that

f(x)=ax^3+bx^2+cx+d

f(0)=-3,f(1)=2,f(3)=5 and f(4)=0

We have to find the polynomial

Substitute the value x=0 then ,we get

f(0)=d=-3

Substitute x=1 then we get

a+b+c-3=2

a+b+c=2+3=5

a+b+c=5 (equation I)

Substitute x=3 then we get

a(3)^3+b(3)^2+c(3)-3=5

27a+9b+3c=5+3=8

27a+9b+3c=8  (Equation II)

Substitute x=4 then we get

a(4)^3+b(4)^2+c(4)-3=0

64a+16b+4c=3 (Equation III)

Equation I multiply by 3 then subtract from equation II

24a+6b=-7 (Equation IV)

Equation II multiply by 4 and equation III multiply by 3 and subtract equation II from III

84a+12b=-23 (Equation V)

Equation IV multiply by 2 and then subtract from equation V

36a=-9

a=-\frac{9}{36}

a=-\frac{1}{4}

Substitute the value of a in equation IV then we get

24(-\frac{1}{4})+6b=-7

-6+6b=-7

6b=-7+6=-1

b=-\frac{1}{6}

Substitute the value of b in equation I then we get

-\frac{1}{4}-\frac{1}{6}+ c=5

-\frac{5}{12}+c=5

c=5+\frac{5}{12}=\frac{65}{12}

Substitute the values then we get

f(x)=-\frac{1}{4}x^3-\frac{1}{6}x^2+\frac{65}{12}x-3

It was recently estimated that homes without children outnumber homes with children by about seven to five. If there are 2556 ho
nekit [7.7K]

Answer:

929  

Step-by-step explanation:

For every 11 children, 7 will have homes and 4 will not.

The fraction of children without homes is 4/11.

The number of children without homes is

4/11 × 2556 = 929

 

Check:

The number of children with homes is 2556 - 929 = 1627

With/Without = 1627/929 = 7.005/4 ≈ 7/4

OK.
