There are multiple chickens and rabbits in a cage. There are 72 heads and 200 feet inside of the cage. How many chickens are in

sleet_krkn [62]

Given:
Chicken
Rabbit
72 heads
200 feet

Chicken - 1 head , 2 feet
Rabbit - 1 head , 4 feet

C + R = 72
2C + 4R = 200

C = 72 - R
2(72-R) + 4R = 200
144 - 2R + 4R = 200
2R = 200 - 144
2R = 56
R = 56/2
R = 28

C = 72 - 28
C = 44

2C + 4R = 200
2(44) + 4(28) = 200
88 + 112 = 200
200 = 200

There are 44 CHICKENS and 28 RABBITS.

Please explain as well, solve the trigonometric equation

aliina [53]

Given:

The trigonometric equation is:

$\tan x\sin x=\tan x\cos x$

To find:

The solutions for the given equation over $0^\circ$ .

Solution:

We have,

$\tan x\sin x=\tan x\cos x$

It can be written as

$\tan x\sin x-\tan x\cos x=0$

$\tan x(\sin x-\cos x)=0$

$\tan x=0$ and $(\sin x-\cos x)=0$

The solutions over $0^\circ$ are:

$x=90^\circ,180^\circ$ and $\sin x=\cos x$

$x=90^\circ,180^\circ$ and $x=45^\circ, 225^\circ$

Therefore, the correct option is D.

The function f(x) is graphed. It represents a translation of the square root function y = .

Brums [2.3K]

Answer:

f(x) = (√x) + 3

Step-by-step explanation

This function is a translation of the parent function, f(x) = √x. A translation slides a graph. In this case, we can see that the function has been slid, or shifted, 3 units up. This is represented in a function by adding 3 to the end of the function; thus it is f(x) = (√x) + 3.
