7049 needs to be rounded to the nearest thousand = 7000

1859 needs to be rounded to the nearest hundred = 1900

7000+1900= 8900

Daniel is paid $10 per week for selling newspaper subscriptions. He is also paid $3.50 for each new customer (x) that signs up f
Aliun [14]
Alright so, since it says that he eats at least $10 dollars no matter what we can basically leave that alone. next week have $3.50 for every new customer (x) so we could write this as $3.50x. and lastly we have Y the amount he will earn every week.

so the equation would be $10+$3.50x=Y.

if we had more information we might be able to solve for Y but since it doesn't tell us how many he sold we would leave it like that.

Determine the area of the composite figure.
MaRussiya [10]

Answer:

110\ in^2

Step-by-step explanation:

1)\ A_1 = b * h_1 = 10 * 8 = 80\ in^2

2)\ A_2 = \frac{b*h_2}{2} = \frac{10*(14-8)}{2} = \frac{10*6}{2} = \frac{60}{2} = 30\ in^2

3)\ A = A_1 + A_2 = 80 + 30\ in^2 = 110\ in^2

Not sure how to approach this one, any help would be appreciated!
iren2701 [21]
The continuity of f' and its limiting behavior guarantees that f' is Riemann integrable, so you can write

\displaystyle\int_0^\infty f'(x)\,\mathrm dx=uv\bigg|_{x=0}^{x\to\infty}-\int_0^\infty v\,\mathrm du

where u=1\implies\mathrm du=0\,\mathrm dx and \mathrm dv=f'(x)\,\mathrm dx\implies v=f(x), so that

\displaystyle\int_0^\infty f'(x)\,\mathrm dx=f(x)\bigg|_{x=0}^{x\to\infty}=\lim_{x\to\infty}f(x)-f(0)=-f(0)
