If dy/dx=1/x, then the average rate of change of y with respect to x on the closed interval [1, 4] is a) -1/4
b) (1/2)*ln(2)
c) (2/3)*ln(2)
d) 2/5
e) 2

Answers

The first thing to do here is to integrate the ordinary differential equation dy/dx = 1/x. This is equal to y = ln x + C. Assuming C is zero. y = lnx. substituting the two interval,
y1 = 0 y2 = ln 4
the rate of change then is equal to (ln4 - 0) / (4-1) equal to 2/3 ln 2. Answer is C

What is the solution to the linear equation? 6k+10.5=3k+12

Answers

Answer:

$k=0.5$

Step-by-step explanation:

Given: The linear equation $6k+10.5=3k+12$ .

To find: The solution of the linear equation.

Solution: The given linear equation is:

$6k+10.5=3k+12$

Rewriting the like terms, we get

$6k-3k=12-10.5$

Solving the above equation, we have

⇒ $3k=1.5$

⇒ $k=(1.5)/(3)$

⇒ $k=0.5$

which is the required solution to the linear equation.

the answer is k=0.5 hope it helps

What is fx over gx when fx is -2x^3+x^2+16x-15 and gx is x + 3

Answers

If f(x)=-2x³+x²+16x-15 and g(x)=x+3, we can substitute the polynomial in for f(x) and the binomial for g(x) like so:
$(2 x^(3)+ x^(2)+16x-15 )/(x+3)$

The next step is to factor the numerator by grouping in the hopes that something will cancel!
$((2 x^(3)+ x^(2)) +(16x-15) )/(x+3) \n ( x^(2) (2x+1)+16x-15)/(x+3)$

Unfortunately, because we can't factor anything out of the second grouped pair, that means there's no simplifying possible! So...
$(f(x))/(g(x)) = (2 x^(3)+ x^(2) +16x-15 )/(x+3)$

Hope this helps!

Show a way to count from 170 to 410 using tens and hundreds. circle at least 1 benchmark number

Answers

Okay, so we start at 170

170

then we add 30 to reach the number 200

170+30=200

then we add 200 to reach the number 400

200+200=400

then we add 10 to reach 410

400+10=410

The benchmark numbers are bolded...
