Elina [12.6K]

Answer: 0.15p+1.59n ≤ 5.00

Step-by-step explanation:

Given: A pencil costs $0.15, and a The notebook costs $1.59.

Let p = Number of pencils.

n = Number of notebooks.

Total cost of pencil and notebook = 0.15p+1.59n

Since Mayumi has $5.00.

So, Total cost of pencil and notebook ≤ $5.00

⇒ 0.15p+1.59n ≤ 5.00

Hence, the required inequality: 0.15p+1.59n ≤ 5.00

Question attached as screenshot belowPlease help me with my calculus homework I am paying close attention

Wewaii [24]

Given:

$\int ^1_{-1}\frac{1}{x^2+1}dx$

To evaluate:

As we know,

$\int ^{}_{}\frac{1}{x^2+1^{}}dx=\tan ^{-1}(x)+C$

So, we have

$\begin{gathered} \int ^1_{-1}\frac{1}{x^2+1}dx=\tan ^{-1}(1)-\tan ^{-1}(-1) \\ =\frac{\pi}{4}-(-\frac{\pi}{4}) \\ =\frac{\pi}{4}+\frac{\pi}{4} \\ =\frac{2\pi}{4} \\ =\frac{\pi}{2} \end{gathered}$

Hence, the answer is,

$\frac{\pi}{2}$
