4 thousands divided by 10 equals blank hundreds
Answer:
40 hundred
Step-by-step explanation:
it is 40 hundred because if you do 4000 divided by 10 you will just need to minus a zero at the end which will become 400.
4 thousand divided by 10 equals 4 hundred.
Given,
4 thousand divided by 10 = _______ hundreds.
We need to fill in the blanks.
We need to know the multiplication of 10 and how to convert 4 thousand into a number.
What are the multiples of 10?10 x 1 = 10
10 x 2 = 20
10 x 3 = 30
10 x 4 = 40
10 x 5 = 50
10 x 6 = 60
10 x 7 = 70
10 x 8 = 80
10 x 9 = 90
10 x 10 = 100.
4 thousand can be written as 4000.
We need to divide 4000 by 10.
4000 ÷ 10
4000 / 10
400
We have 4 hundred.
Thus, 4 thousand divided by 10 equals 4 hundred.

Rt+Rs=st solve for s
Simplifying Rs = st + -1Rt Solving sR = st + -1tR Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-1st' to each side of the equation. sR + -1st = st + -1st + -1tR Combine like terms: st + -1st = 0 sR + -1st = 0 + -1tR sR + -1st = -1tR Combine like terms: -1tR + tR = 0 sR + -1st + tR = 0

the object is dropped from the height of 100 m.reached to ground in 10 seconds. find the acceleration of falling object.
======================================================
Work Shown:
The given values are
vi = 0 = initial velocity (meters per second)d = 100 = distance traveled (in meters)t = 10 = time in secondsPlug those items into the equation below. Solve for 'a'
d = vi*t + (1/2)*a*t^2
100 = 0*10 + (1/2)*a*10^2
100 = 0 + 50a
100 = 50a
50a = 100
a = 100/50
a = 2
The object is falling with an acceleration of 2 m/s^2
This is far below the acceleration of gravity on earth (which is roughly 9.81 m/s^2), so perhaps this object is being dropped on a smaller planet.

Answer:
E
Step-by-step explanation:
You can see from the first and last points that the data set demonstrates a slight upward trend. That means the slope of the regression line will be near +1, eliminating all choices except A and E.
The y-intercept of such a line will not be negative, eliminating choice A, leaving choice E as the only reasonable option.
__
If you input this data to a suitable calculator or spreadsheet, it can find the parameters of the regression line for you. (We presume you have been introduced to such tools.) My graphing calculator gave the results shown below, confirming E is the correct choice.

Step-by-step explanation:

I hope I helped you^_^
The value of 0.16 x 42.1 x 8.73 after multiplying is 58.80528.
Given,
(0.16)(42.1)(8.73)
We need to multiply the decimal numbers.
How do we multiply decimal numbers?When we multiply decimal numbers the decimal point should be placed after the number of counts from the right side.
The number of counts is the sum of the counts of numbers before the decimal point of each decimal number from the right side.
Example:
1.23 x 134.5
Here,
In 1.23 there are two numbers before the decimal point.
In 134.5 there is one number before the decimal point.
So the count = 2 + 1 = 3
So,
There should be three numbers after the decimal point in 1.23. x 134.5.
1.23. x 134.5 = 165.435
Find 0.16 x 42.1 x 8.73 by multiplying.
We see that,
There are two numbers after the decimal point in 0.16
There are one numbers after the decimal point in 42.1
There are two numbers after the decimal point in 8.73
So,
2 + 1 + 2 = 5 numbers
There should be 5 numbers after the decimal point in 0.16 x 42.1 x 8.73
Now,
0.16 x 42.1 x 8.73 = 58.80528.
Thus the value of 0.16 x 42.1 x 8.73 is 58.80528.

A composite function is the combination of two or more functions to create another function. The value of (f o g)(1) is 126
Given that:
[tex]f(x) = 2x^2 + 4x + 15[/tex]
[tex]g(x) = 2x^2 + 4x[/tex]
[tex](f\ o\ g)(x)[/tex] is calculated as:
[tex](f\ o\ g)(x) = f(x) \times g(x)[/tex]
So, we have:
[tex](f\ o\ g)(x) = (2x^2 + 4x + 15) \times (2x^2 + 4x)[/tex]
Substitute 1 for x
[tex](f\ o\ g)(1) = (2 \times 1^2 + 4 \times 1 + 15) \times (2 \times 1^2 + 4 \times 1)[/tex]
[tex](f\ o\ g)(1) = (21) \times (6)[/tex]
[tex](f\ o\ g)(1) = 126[/tex]
Hence, the value of (f o g)(1) is 126

What is graph?A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
For example, if the graph of a function is rising upwards after a certain value of x, the function must be having increasingly output for inputs greater than that value of x.
If the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
The function that we are given graphed has the point (0,1), this means whichever function f(x) it represents f(0) = 1.
Now, only the cosine function has the property that cos(π) = -1, thus
y = cos (x/2)
because from the graph x = 2π
