Can't do number line

... but the is 20.. cause if you do 45-25=20 .. and the bigger number with the sign of positive or negative wins.. do .. -25 post cause Is not big and 45 won cause is a bigger number and positive so the answer is possible 20

Please help me finish this last one(question) for 21 points.

AnnZ [28]

Step-by-step explanation:

The tables rule is y = x²+x. Thus, the three missing boxes from top to bottom are 6, 5, and 2. Two other rows could be x = 13, y = 182, and x = 0, y = 0.

Hope it helps <3

Richland's Real GDP per person is #10b and poorland's Real GDP per person is #5b. However, Richland's Real GDP per person is gro

masya89 [10]

Answer:

after 5 years, rich : poor = 11.0 : 6.7
after 10 years, 12.2 : 9.0
35.3 years

Step-by-step explanation:

It is convenient to let a graphing calculator show the answers to these questions.

The exponential equation modelling the growth will be of the form ...

f(x) = (initial value) × (1 +growth rate)^x

Richland's GDP/person can be modeled by r(x) = 10·1.01^x

Poorland's GCP/person can be modeled by p(x) = 5·1.03^x

The attached graph shows values for x=5, 10 and r(x)=p(x).

It will take about 35.3 years for Poorland to catch up.

II. Let f(x) = 9 – x , g(x) = x2 + x, and h(x) = x – 2. Compute the following:

Neko [114]

Answer:

$h(g(x))=x^2+x-2$

$h(g(f(x))= x^2-19x+88$

Step-by-step explanation:

<u>Composite Function</u>

Suppose f(x) and g(x) are real functions, the composite function named $(f\circ g)(x)$ is defined as:

$(f\circ g)(x)=f(g(x))$

The composite function can be found by substituting g into f.

We are given these functions:

$f(x)=9-x$

$g(x)=x^2+x$

$h(x)=x-2$

Find:

a) h(g(x))

Substituting g into h:

$h(g(x))=x^2+x-2$

b) h(g(f(x))

First we find g(f(x)):

$g(f(x))=(9-x)^2+(9-x)$

Operating:

$g(f(x))=81-18x+x^2+9-x$

Simplifying:

$g(f(x))=90-19x+x^2$

Now find h(g(f(x)) replacing the above equation into h:

$h(g(f(x))= 90-19x+x^2-2$

Simplifying and rearranging:

$h(g(f(x))= 88-19x+x^2$

$h(g(f(x))= x^2-19x+88$

Convert 525 pounds to kilograms.Show your dimensional analysis setup. 1 kilogram=2.2 pounds.

Ostrovityanka [42]

In this case, the starting amount is 525 pounds. You want to convert it into kilograms so you need to know the equal amount of pounds into one kilogram. The equal amount is: 1kilogram/ 2.2 pounds.

To convert it you simply need to multiply the starting amount with the equal amount, then the calculation is:
525 pounds x 1 kilogram/2.2pound= 525 kilogram / 2.2= 238.63 kilograms.

Then the end amount is 238.63 kilograms
