Answer:

Point B

Step-by-step explanation:

√11 is 3.3

And A is about 2. Something and inbetween D and E is 4 which means C will be 3.5

So it leaves it at B

igor_vitrenko [27]

Answer: 1680 inches cubed

Step-by-step explanation:

Volume = Length x Width x Height

V = 20 x 7 x 12

V = 140 x 12

V = 1680 inches cubed

a friend is having trouble with exponents and asks you to review some worked probelems look over the problems and correct any mi

Stella [2.4K]

We have the following expression:

$2x^2y\cdot3x^5y^2$

By combining similar terms, we get

$2\cdot3\cdot x^2\cdot x^5\cdot y\cdot y^2$

now, 2 times 3 is 6 and to add exponents, both the exponents and variables should be alike:

$x^2\cdot x^5=x^{2+5}=x^7$

Similarly,

$y\cdot y^2=y^{1+2}=y^3$

Therefore, the answer is

$6x^7y^3$

Find the area between the graph of the function and the x-axis over the given interval, if possible.

vodomira [7]

Answer:

$A= -\frac{5}{-1} - \lim_{x\to\infty} \frac{5}{x-2} = 5-0 = 5$

So then the integral converges and the area below the curve and the x axis would be 5.

Step-by-step explanation:

In order to calculate the area between the function and the x axis we need to solve the following integral:

$A = \int_{-\infty}^1 \frac{5}{(x-2)^2}$

For this case we can use the following substitution $u = x-2$ and we have $dx = du$

$A = \int_{a}^b \frac{5}{u^2} du = 5\int_{a}^b u^{-2}du$

And if we solve the integral we got:

$A= -\frac{5}{u} \Big|_a^b$

And we can rewrite the expression again in terms of x and we got:

$A = -\frac{5}{x-2} \Big|_{-\infty}^1$

And we can solve this using the fundamental theorem of calculus like this:

$A= -\frac{5}{-1} - \lim_{x\to\infty} \frac{5}{x-2} = 5-0 = 5$

So then the integral converges and the area below the curve and the x axis would be 5.

If A and B are two points having coordinates (- 2, 2) and (2,-4) respectively, find the coordinates of P such that AP= AB.

Karo-lina-s [1.5K]

Answer:

(0,1)

Step-by-step explanation:

The mid point of A(-2,2) and B(2,-4) is the coordinates of point P, which is (x,y)

Hence, the line AB = AP + PB.

At point AP: x = (-2+2)/2 = 0

also, point PB: y = (2 - 4)/2 = -1

Therefore, coordinates of point P = (0,-1)
