Answers

Answer 1

Answer:

Answer:

Option C.300

Step-by-step explanation:

we know that

To find out how many times greater is the land area of the United States than that of Norway, divide the area of the United States by the area of the Norway

$(9*10^6)/(3*10^4)$

Remember that

To divide exponents (or powers) with the same base, subtract the exponents

$(9*10^6)/(3*10^4)=((9)/(3))*(10^(6-4) )=3*10^2=300$

If h(x)=x-7 and g(x)=x^ which expression is equivalent to (g•h)(5)?A) (5-7)^
B) (5)^-7
C) (5)^ (5-7)
D) (5-7)x^

Answers

Answer:

A (5-7)^

Step-by-step explanation:

We have the next two functions h(x)=x-7 and g(x)=x^. We need to find (g•h) that is equal to g(h(x)) then:

(g•h)=g(h(x))=(x-7)^

Finally in the poin x=5 we have:

(g•h)=g(h(x))=(x-7)^

(g•h)=g(h(5))=(5-7)^

Then the answer is A

Assuming that by ^, you mean ², here's how you do this:
(g•h)(5) means that you need to solve g(h(5)). So, you plug 5 in for x in h(x), then you plug the solution of that in for x in g(x) like so:
$h(5)=5-7 \n g(h(5))= (5-7)^(2)$

The answer is A. (5-7)²

How do I solve this?The Sugar Sweet Company is going to transport its sugar to market. It will cost $4900
to rent trucks, and it will cost an additional $175 for each ton of sugar transported. Let
C represent the total cost (in dollars), and let S represent the amount of sugar (in tons) transported. Write an equation relating C to S, and then graph your equation using the axes below.

Answers

C = 4900 + 175S

The graph will cross the y-axis at 4900 and show a slope of 175/1 . Good luck graphing. If you choose the right scale, the graph will be easier. Increment by by 500 on the yaxis and 25 on the x-axis.

What are the zero(s) of the function f(x) = the quantity of 5 x squared minus 25 x, all over x? x = 5 x = 0 and x = 5

Answers

Answer:

x=5

Step-by-step explanation:

$f(x)= (5x^2-25x)/(x)$

To find out zeros we replace f(x) with 0

$0= (5x^2-25x)/(x)$

Now solve for x

first we divide the numerator by x

$0=5x-25$

Now we facor out GCF 5

$0=5(x-5)$

Divide by 5 on both sides

$0=x-5$

Add 5 on both sides

x= 5

zero of the function is x=5

(5x^2-25x)/x
simplify
((x)(5)(x-5))/x=5(x-5)=5x-25=f(x)
(just fyi, that x we cancled is a hole)
set to zero
5x-25=0
5x=25
divide 5
x=5

zeroe is at x=5
or (5,0)

x=5 is answer
