Answer:

As follows,

Step-by-step explanation:

Find the attachment.

Distance of PQ=√13

Distance of QR=√13

Distance of PR=√26

Thus, PQR is an isosceles triangle.

Distance of MN=√(16+(a-2)^2)

16=16+a^2-4a+4

a^2-4a+4=0

a=2

Distance of RS=√(9+(b+1)^2)

25=9+b^2+2b+1

b=3 or -5

Distance of RS=√(9+(-1-c)^2)

18=9+c^2 + 2 c + 1

c=-4,2

Ad libitum [116K]
The intersection between the curves are
3, 0
0, 3
The volume of the solids is obtained by
V = ∫ π [ (4 - (y-1)²)² - (3 - y)²] dy with limits from 0 to 3
The volume is
V = 108π/5 or 67.86

Multi step equations 4x+6+3=17
Kobotan [32]
First, you add like terms.  In this case, the like terms are 6 and 3.

4x + 6 + 3 = 17
4x + 9 = 17

Then, subtract 9 on each side:

4x + 9 - 9 = 17 - 9
4x = 8

Then divide by 4 on each side to get the x by itself:

4x/4 = 8/4
x = 2

I’d go with D, you do 350 and multiply it by 0.0425 and do the same with 450 and multiply by 0.0425 and you multiply each of those answers and then add them to 800

Please help with this Math Question...
Nataly [62]

Answer: A

<u>Step-by-step explanation:</u>

f(x) = x³ + 4x² + 7x + 6

possible rational roots are ±{1, 2, 3, 6}

Try x = -2

-2 |   1   4   7   6

   <u>|   ↓  -2  -4  -6</u>

       1    2    3   0 ← remainder is 0 so x = -2 is a root  ⇒  (x + 2) = 0

The factored polynomial x² + 2x + 3 = 0 is not factorable so use the quadratic formula to find the roots.

a=1, b=2, c=3

x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a}

x=\dfrac{-(2)\pm\sqrt{(2)^2-4(1)(3)} }{2(1)}

x=\dfrac{-2\pm\sqrt{4-12} }{2}

x=\dfrac{-2\pm\sqrt{-8} }{2}

x=\dfrac{-2\pm2i\sqrt{2}}{2}

x = -1 \pm i\sqrt{2}

x = -1 + i\sqrt{2}       x = -1 - i\sqrt{2}

x - (-1 + i\sqrt{2})=0       x - (-1 - i\sqrt{2})=0

The factors are:

(x - 2)[x - (-1 + i\sqrt{2})][x - (-1 - i\sqrt{2})]
