Answer:

Isosceles triangle

Step-by-step explanation:

Length of side AB = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

= $\sqrt{(-11+3)^2+(2-6)^2}$

= $\sqrt{64+16}$

= $\sqrt{80}$

= 4 $\sqrt{5}$

Length of BC = $\sqrt{(-4+11)^2+(-2-2)^2}$

= $\sqrt{49+16}$

= $\sqrt{65}$

Length of AC = $\sqrt{(-3+4)^2+(6+2)^2}$

= $\sqrt{1+64}$

= $\sqrt{65}$

Since, AC = BC, ΔABC will be an isosceles triangle.

Find the volume of the solid whose base is the circle x2+y2=25 and the cross sections perpendicular to the x-axis are triangles

ivanzaharov [21]

Triangles with height $h$ and base $b$ , with $b=h$ have area $\dfrac{b^2}2$ .

Such cross sections with the base of the triangle in the disk $x^2+y^2\le25$ (a disk with radius 5) have base with length

$b(x)=\sqrt{25-x^2}-\left(-\sqrt{25-x^2}\right)=2\sqrt{25-x^2}$

i.e. the vertical (in the $x,y$ plane) distance between the top and bottom curves describing the circle $x^2+y^2=25$ .

So when $x=4$ , the cross section at that point has base

$2\sqrt{25-16}=6$

so that the area of the cross section would be 6^2/2 = 18.

In case it's relevant, the entire solid would have volume given by the integral

$\displaystyle\int_{-5}^5\frac{b(x)^2}2\,\mathrm dx=4\int_0^5(25-x^2)\,\mathrm dx=\frac{1000}3$

Suppose that A, B, C, are independent random variables, each being uniformly distributed over (0, 1). (a) What is the joint cumu

Gekata [30.6K]

Answer:

a) F (A , B,C)(a,b,c) = abc

b) Answer is in derivative

Step-by-step explanation:

Hence area is maximum x=6

For ( a,b,c) ∈ (0,1)

We have that

F A, B,C (a,b,c) = A≤ a , B≤ b , C≤c

=P (A≤a) P (B≤b) P (C≤c)

A , B, C ≈ unit (0,1) we have that

P (A≤a) =a

P (B≤b) =b

P (C≤c)=c

Thus

F (A , B,C)(a,b,c) = abc

b) Answer is in derivative

The original cost of Sam’s investment is $10,000. After liquidating the investment, Sam calculated his real return to be $10,700

Sati [7]

Answer:

Step-by-step explanation:

Step one:

given data

The original cost of Sam’s investment is $10,000

Sam calculated his real return to be $10,700

Required:

the interest made from the investment is

10700-10000= $700

Step two:

The ROI is a percentage that tells us the interest made

interest/investment*100

=700/10000*100

=0.07*100

= 7%

The ROI is 7%
