If the angles of a quadrilateral measure 67 degrees 123 degrees and 58 degrees what is the measure of the other angle

The other angle measures 112°.
All the angles in any 4-sided polygon will add up to 360°, like how all angles in a triangle add up to 180°. A good way to remember this is with the sum of interior angles formula:
180 x (n - 2), where n is the number of sides.

Find the volume of the solid generated by revolving the region bounded by

Rama09 [41]

Answer:

$V =\dfrac{25\pi}{\sqrt{2}}$

Step-by-step explanation:

given,

y=5√sinx

Volume of the solid by revolving

$V = \int_a^b(\pi y^2)dx$

a and b are the limits of the integrals

now,

$V = \int_a^b(\pi (5\sqrt{sinx})^2)dx$

$V =25\pi \int_{\pi/4}^{\pi/2}sinxdx$

$\int sin x = - cos x$

$V =25\pi [-cos x]_{\pi/4}^{\pi/2}$

$V =25\pi [-cos (\pi/2)+cos(\pi/4)]$

$V =25\pi [0+\dfrac{1}{\sqrt{2}}]$

$V =\dfrac{25\pi}{\sqrt{2}}$

volume of the solid generated is equal to $V =\dfrac{25\pi}{\sqrt{2}}$

Find the vertices of the hyperbola. Enter the smallest coordinate first.

melisa1 [442]

Answer:

([-3], [0]), ([3], [0])

Step-by-step explanation:

The given equation of the hyperbola is presented as follows;

$\dfrac{x^2}{9} - \dfrac{y^2}{49} = 1$

The vertices of an hyperbola (of the form) $\dfrac{x^2}{a^2} - \dfrac{y^2}{b^2} = 1$ are (± a, 0)

The given hyperbola can we presented in a similar form as follows;

$\dfrac{x^2}{9} - \dfrac{y^2}{49} = \dfrac{x^2}{3^2} - \dfrac{y^2}{7^2} = 1$

Therefore, by comparison, the vertices of the parabola are (± 3, 0), which gives;

The vertices of the parabola are ([-3], [0]), ([3], [0]).
