A fairly recent alternative to algebraic modeling is spreadsheet modeling, which, instead of relating various quantities with algebraic equations and inequalities, relates them in a spreadsheet with cell formulas.a) trueb) false

Answers

Answer 1

Answer:

True

Step-by-step explanation:

With the advent and proliferation of the use of computers, data can now be analyzed with the aid of spreadsheets. These spreadsheets such as the one found in Microsoft Excel are arranged in grids whereby, the rows are numbered and the columns are identified with alphabets. The data entered in the spreadsheet are guided by formulas which can be found on the formula tool bar.

The formula gives an insight into the calculation performed for the list of items provided in the grid. There are several mathematical functions that aid in the calculations, such as the SUM and DIV functions.

How do you solve this 4x-2+x= -2+2x

Answers

Answer:

0

Step-by-step explanation:

First of all, simplify the equation on both sides. You will get 5x - 2 = 2x - 2. Add two to both sides, and you get 5x=2x. Subtract 2x from both sides to get 3x=0, so x will equal 0.

Answer:

5x = 2x

Step-by-step explanation:

5x- 2 = 2 + 2x

Step-by-step explanation:

the 100th place is the 2nd digit in the decimal. After the "7" is "27" so it rounds down to just ".8700." We don't include the "infinite zeros" or whatever so therefore your answer is 367.87.

A car, initially at rest, travels 20 m in 4 s along a straight line with constant acceleration. The acceleration of the car is: 1. 0.4 m/s 2 2. 9.8 m/s 2 3. 4.9 m/s 2 4. 1.3 m/s 2 5. 2.5 m/s 2

Answers

Answer:

2.5m/s²

Step-by-step explanation:

Using the equation of motion S = ut + 1/2at² where;

S is the distance travelled = 20m

u is the initial velocity = 0m/s (car starts from rest)

a is the acceleration = ?

t is the time taken = 4s

To get the acceleration of the car, we will substitute the given parameters into the given equation.

S = ut + 1/2at²

20 = 0(4)+1/2a(4)²

20 = 0+ a/2*16

20 = 8a

divide both sides by 8

20/8 = 8a/8

20/8 = a

a = 20/8

a = 2.5m/s²

Hence the acceleration of the car is 2.5m/s²

Step-by-step explanation: Midpoint of a segment is halfway between 2 endpoints. It is calculated using the formulas:

[tex]x_{m}=\frac{x_{1}+x_{2}}{2}[/tex]

[tex]y_{m}=\frac{y_{1}+y_{2}}{2}[/tex]

Isolating [tex]x_{2}[/tex]:

[tex]x_{2}=2x_{m}-x_{1}[/tex]

And [tex]y_{2}[/tex]:

[tex]y_{2}=2y_{m}-y_{1}[/tex]

(a) Replacing values and calculating [tex]x_{2}[/tex]:

Can 6,12, and 18 make a triangle?

Answers

By definition, 3 side lengths are a triangle if any 2 side lengths add up to be greater than the third.

We can already see that the side lengths 6 and 12 will add up to a value of 18, which is equal to the last side length, meaning that the three values are not a triangle.

[tex]a=6[/tex]

[tex]b=12[/tex]

[tex]c=18[/tex]

[tex]a+b>c[/tex]

[tex]b+c>a[/tex]

[tex]c+a>b[/tex]

[tex]6+12>18[/tex] (Since this is not true, this is not a triangle)

f(x) = 9 - x, g(x) = x2 + x, h(x) = x - 2
Compute the following:
f(g(4)

Answers

Answer:

f(g(4) = -11

Step-by-step explanation:

Whenever we are given a composite function where the output of one of the functions serves as an input for the second one, the first step is to evaluate the numerical output from the first function.

Output from first function: g(x) = [tex]x^{2} + x[/tex]

g(4) will be evaluated by substitution 4 for x in the above equation.

this will give us [tex]g(x)=4^{2}+4 =20[/tex]

Output from the composite function f(g(4)

The next stage is to input our results from the function g(4) into the function

f(x) = 9 - x. The output from g(4) which is 20, will now become our input.

[tex]f(x)-9-(20)= -11[/tex]

Therefore f(g(4) = -11

If one kilogram equals 2.2 pounds, how many kilograms equal 112 pounds? Round your answer to the nearest hundredth, if necessary. 24.64 kilograms 50.91 kilograms 109.8 kilograms 246.4 kilograms

Answers

Answer:

B.) 50.91 kilograms

Step-by-step explanation:

Write an equation that looks like this:

[tex]\frac{kilogram}{pound}= \frac{kilogram}{pound}[/tex]

Insert the information in the appropriate section, with 1 kilogram and 2.2 pounds on the same side:

[tex]\frac{1}{2.2}=\frac{x}{112}[/tex]

Solve for x, which is the number of kilograms for 112 pounds if there is 1 kilogram per 2.2 pounds.

Solve for x. Cross multiply:

[tex]1(112)=2.2(x)\\\\112=2.2x[/tex]

Isolate the variable. Divide both sides by 2.2:

[tex]\frac{112}{2.2}=\frac{2.2x}{2.2}\\\\x= 50.909090...[/tex]

Round to the nearest hundredth (two decimal places to the right):

50.909 → 50.91

If 1 kilogram is equal to 2.2 pounds, then 50.91 kilograms is equal to 112 pounds.
