1) Round 168,356 to the nearest ten thousand.2) Round 446,221 to the nearest ten3) Round 45,122 to the nearest ten thousand.4) Round 7,782 to the nearest hundred.

Answers

Answer:

1) 170,000

2) 446,220

3) 50,000

4) 7,800

Step-by-step explanation:

When we round a number to the nearest hundred then we check the digit at tens place,

If the digit is less than 5 then the number is rounded to previous thousand and if it is 5 more than 5 it is rounded to the next thousand,

While, in the case of rounding nearest ten and ten thousand we check the digit at ones place and thousand placerespectively.

1)168,356 to the nearest ten thousand is 170,000 ( ∵ thousand place digit = 8 > 5 )

2) 446,221 to the nearest ten is 446,220 ( ∵ ones place digit = 1 < 5 )

3) 45,122 to the nearest ten thousand is 50,000 ( ∵ thousand place digit = 5 ≥ 5 )

4) 7,782 to the nearest hundred is 7,800 ( ∵ tens place digit = 8 > 5 )

1)170,000
2)446,220
3)50,000
4)7,800

On a coordinate plane how can a equation of the line be identified as proportion or nonproportional

Answers

I think the equation of the line can be identified as a proportion because if it was non-proportion, there would be no equation. Hope it helps!

Let f(x)=e* and g(x)= X+6. What are the domain and range of (gºf)(x)?

Answers

Answer:

Domain: Set of All Real Numbers. (-∞, ∞)

Range: (0, ∞)

Step-by-step explanation:

$f(x)=e^(x)\ng(x)=x+6$

We need to evaluate (gof)(x). (gof)(x) means the composition of function g(x) and f(x). In order to find (gof)(x) replace every occurrence of x in g(x) with the expression of f(x) as shown below:

$(gof)(x)=g(f(x))\n\n =g(e^(x))\n\n =e^(x)+6$

We have to find the domain and range of this composite function.

Domain:

The expression $e^(x)+6$ is defined for all Real Numbers. It never gets undefined for any value of x. Hence the Domain is set of All Real Numbers.

Range:

The range of the parent exponential function $e^(x)$ is from 0 to positive infinity. The expression $e^(x)+6$ can be related to $e^(x)$ as a vertical shifted function by 6 units upward. As a result the range will also be shifted up. So the range of the composite function will be from 6 to positive infinity. In interval notation this would be expressed as: (0, ∞)
