The area of the region in the first quadrant between the graph of y = k*sin(x) and x-axis (where k > 0 ) on the closed interv

astraxan [27]

Note that $0\le k\sin x\le k$ in the given closed interval, so the area is exactly given by the definite integral

$\displaystyle\int_0^\pi k\sin x\,\mathrm dx$

(no absolute values needed!)

Integrating gives

$-k\cos x\bigg|_{x=0}^{x=\pi}=-k(\cos\pi-\cos0)=-k(-1-1)=2k$

Annie spent $20.02 at the post office. She bought 2 times as many 32-cent stamps as 13-cent stamps. How many of each did she buy

ivolga24 [154]

Answer:

52 32- cent stamps and 26 13-cent stamps

Step-by-step explanation:

Let x be the 32-cent stamps and y be the 13-cent stamps then...

x=2y

32x+13y=2002 (note that $20.02 is 2002 cents)

We can solve using substitution (substitute 2y for x)

32(2y)+13y=2002

64y+13y=2002

77y=2002

y=26

x=2(26)

x=52

She bought 52 32-cent stamps and 26 13-cent stamps.

What is the value of 7x 2squared + 2x when x = 3?

mash [69]

Answer:

Given expression has the value 69

Step-by-step explanation:

Given equation is:

$=7x^2 + 2x$

Now we have to put x = 3

So the equation will become:

$=7(3)^2 + 2(3)$

By simplifying:

As $3^{2} = 9$

and 2*3 = 6

So the above equation will become:

$=7(9 ) + 6\\= 63 + 6\\= 69$

So the value of given expression is 69.

i hope it will help you!
