<span>To find out how many gallons in cups, multiply by the right conversion factor or simply use the converter below for fluid gallons. SO you have 5 gallons of water and that will give you 80 cups. Hope this helps. :)</span>

Which value of x does not satisfy the equation sin^2x + sin x = 0

zzz [600]

Answer:

$x \neq 0 \pm \pi \cdot i, \forall i \in \mathbb{N}_{O}$ and $x \neq \frac{3\pi}{2}\pm 2\pi \cdot j, \forall j \in \mathbb{N}_{O}$ .

Step-by-step explanation:

The equation can be simplified with the help of trigonometric identities:

$\sin x \cdot (\sin x + 1) = 0$

Which means that equation is equal to zero if any component of the product is zero. The solutions of the expression are:

a) $\sin x$

$x = 0 \pm \pi\cdot i,\forall i \in \mathbb{N}_{O}$

b) $\sin x + 1$

$\sin x + 1 = 0$

$\sin x = -1$

$x = \frac{3\pi}{2} \pm 2\pi\cdot i,\forall i \in \mathbb{N}_{O}$

Any value different of both subsets do not satisfy the equation described above.

Find the area of the triangle with vertices: q(3,-4,-5), r(4,-1,-4), s(3,-5,-6).

maw [93]

Answer:

(√6)/2 square units

Step-by-step explanation:

The area of a triangle is half the magnitude of the cross product of the vectors representing adjacent sides.

QR = (4-3, -1-(-4), -4-(-5)) = (1, 3, 1)

QS = (3 -3, -5-(-4), -6-(-5)) = (0, -1, -1)

The cross product is the determinant ...

$\text{det}\left|\begin{array}{ccc}i&j&k\\1&3&1\\0&-1&-1\end{array}\right|=-2i+j-k$

The magnitude of this is ...

|QR × QS| = √((-2)² +1² +(-1)²) = √6

The area of the triangle is half this value:

Area = (1/2)√6 . . . . square units

Question number 3 pls

marissa [1.9K]

Factoring f(x) would give a factor (x-1-2i), so you can divide f(x) by this, leaving (x-3)(x+4)(x-1+2i), so the other roots are:

x=3
x=-4
x=1-2i
