Segments in Circles<br><br><br> TW=3, CW=x, TU=x+7, VW=6. Find the value of x.

Kryger [21]

Answer:

x=2

Step-by-step explanation:

The diagram is attached below

TW=3
CW=x
TU=x+7
VW=6

TU=TW+WU

x+7=3+WU

WU=x+7-3

WU=x+4

To determine the value of x, we apply the theorem of intersecting chords.

TW X WU = CW X WV

$x(x+4)=6 \times x\\x^2+4x=6x\\x^2=6x-4x\\x^2=2x\\$Divide both sides by x\\x=2$

The diameter of the base of the cone measure 17units the height measures 15units what is the unfilled volume inside the cylinder

777dan777 [17]

Answer:

V = 1134.9

Step-by-step explanation:

Since $V=\pi r^{2}\frac{h}{3}$

Firstly we need to divide 17 by 2 to get the radius which is 8.5

Then we need to solve by putting the values in...

$=\pi$ x $8.5^{2}$ x $\frac{15}{3}$

= 1134.9

Find the midpoint of the line segment with the given endpoints. (-10, 5), (-9, -9)

Mkey [24]

Answer:

$=\left(-\frac{19}{2},\:-2\right)$

Step-by-step explanation:

$\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)\\\\\left(x_1,\:y_1\right)=\left(-10,\:5\right),\:\\\left(x_2,\:y_2\right)=\left(-9,\:-9\right)\\\\=\left(\frac{-9-10}{2},\:\frac{-9+5}{2}\right)\\\\Simplify \\=\left(-\frac{19}{2},\:-2\right)$

Determine n between 0 and 19 such that (2311)(3912) ≡ n mod 20.

sleet_krkn [62]

You can write 2311 and 3912 in the form $20q+r$ :

$2311=115\cdot20+11$

$3912=125\cdot20+12$

Then

$2311\cdot3912=(115\cdot20+11)(125\cdot20+12)$

$2311\cdot3912=115\cdot125\cdot20^2+(11\cdot125+12\cdot115)\cdot20+11\cdot12$

Taken modulo 20, the terms containing powers of 20 vanish and you're left with

$2311\cdot3912\equiv11\cdot12\equiv132\pmod{20}$

We further have

$132=6\cdot20+12$

so we end up with

$2311\cdot3912\equiv12\pmod{20}$

and so $n=12$ .

###

If instead you're trying to find $2311^{3912}\pmod{20}$ , you can apply Euler's theorem. We can show that $\mathrm{gcd}(2311,20)=1$ using the Euclidean algorithm. Then since $\varphi(20)=8$ , and 8 divides 3912, we have
