Answer:

$\large\boxed{B\subset A}$

Step-by-step explanation:

$\O\subset A-\bold{TRUE}\ \text{because the empty set is a subset of any set}\\\\B\subseteq B-\bold{TRUE}\ \text{because}\ B=B\\\\B\subset A-\bold{FALSE}\ \text{because}:\\\\A=\{4,\ 7,\ 10,\ 13,\ 17\},\ B=\{3,\ 5,\ 7,\ 9\}\\\\3\notin A,\ 5\notin A\ \text{and}\ 9\notin A\\\\\text{For}\ B\subset A\ \text{, each element of set B must be in set A.}$

I really need some help. I need to find the inverse of this equation in the picture below. Thanks!

serg [7]

Answer:

y=81x^4+648x^3+1944x^2+2592x+1289

Step-by-step explanation:

1. Interchange x and y.

y=\frac{\sqrt[4]{x+7}}{3}-2

x=\frac{\sqrt[4]{y+7}}{3}-2

2. Then solve x=\frac{\sqrt[4]{y+7}}{3}-2 for y.

3. y=81x^4+648x^3+1944x^2+2592x+1289

I hope this helps.

please help me, a point thief gave a me a silly fake answer the first time, now no one will answer me. Write the given equation

vaieri [72.5K]

4x - 2y = 10
-2y = -4x + 10
y = 4/2x - 10/2
y = 2x - 5 <==

What are the ratios of sine, cosine, and tangent for angle Y? sin(Y) = StartFraction X Z Over X Y EndFraction; cos(Y) = StartFra

Sholpan [36]

Answer:

$\sin Y= \frac{XZ}{XY}$

$\cos Y= \frac{YZ}{XY}$

$\tan Y= \frac{XZ}{YZ}$

Step-by-step explanation:

Given

See attachment for triangle

Required

Find $\sin, \cos$ and $\tan$ of angle Y

For angle Y:

$Opposite = XZ$

$Adjacent = YZ$

$Hypotenuse = XY$

The $\sin$ of an angle is calculated as:

$\sin\theta = \frac{Opposite}{Hypotenuse}$

So:

$\sin Y= \frac{XZ}{XY}$

The $\cos$ of an angle is calculated as:

$\cos\theta = \frac{Adjacent}{Hypotenuse}$

So:

$\cos Y= \frac{YZ}{XY}$

The $\tan$ of an angle is calculated as:

$\tan\theta = \frac{Opposite}{Adjacent}$

So:

$\tan Y= \frac{XZ}{YZ}$
