A number has the digits 2, and 4 to the nearest 100. the number rounds to 200 what is the number

Answers

The number could either be 240 or 204. This is because anywhere below 250 would round down, thus, 240 and 204 would round down to 200. Not sure if I read the question correctly, so reply if I didn't!

Given: Line b is parallel to line c. Line c is parallel to line e. Line a intersects line b. Which of the following statements are you certain is true? Line a is perpendicular to line e. Line a intersects line e. Line a is perpendicular to line c. None of the above is true.

Answers

none of the above is true
The correct answer is that line a intersects line e. This is true because line a intersects line b which is parallel to line e and therefore also intersects line e.

A particular frozen yogurt has 75 cal into ounces how many calories are in 8 ounces of the yogurt

Answers

I'm guessing you mean 75 calories in 2 ounces. 
In that case... you would do
75 / 2 = 37.5
37.5 x 8 = 300 calories in 8 ounces of yogurt

Given the tables for f & g below, find the following: x f ( x ) g ( x ) 0 9 7 1 4 8 2 3 6 3 5 1 4 7 5 5 1 2 6 6 0 7 0 4 8 2 9 9 8 3 Average rate of change of g for x on the interval [3 , 7 ] = 9 Incorrect Average rate of change of f for x on the interval [3 , 7 ] = Incorrect f ( g ( 4 ) ) = Incorrect g ( f ( 3 ) ) = Incorrect

Answers

\n(i)\n\text{We know that the average rate of change of a function f(x) on inerval [a,b] is}\n\nf_(avg)=(f(b)-f(a))/(b-a)\n\n\text{so using this the average rate of chang of g for x on interval }[3,7] \text{ is}\n\ng_(avg)=(g(7)-g(3))/(7-3)\n\n=(4-1)/(4)\n\n=(3)/(4)\n\n\text{so average rate of change of g on interval [3,7] is }(3)/(4)

\n(ii)\n  \text{Average rate of chang of f for x on interval }[3,7] \text{ is}\n\nf_(avg)=(f(7)-f(3))/(7-3)\n\n=(0-5)/(4)\n\n=(-5)/(4)\n\n\text{so average rate of change of g on interval [3,7] is }(-5)/(4)

\n(iii)\n\text{Since g(4)=5, so we have}\n\nf(g(4))=f(5)\n\n\text{since the value of f is 1 at x=5. so }\n\nf(g(4))=f(5)=1\n\n\text{hence we have, }f(g(4))=1

\n(iv)\n\text{Since f(3)=5, so we have}\n\ng(f(3))=g(5)\n\n\text{since the value of g is 2 at x=5. so }\n\ng(f(3))=g(5)=2\n\n\text{hence we have, }g(f(3))=2
