Chickens have 1 head and 2 legs
rabbits had 1 head and 4 legs


total heads is 30
c+r=30
total legs is 98
2c+4r=98
divide by 2
c+2r=49

multiply top equation by -1 and add to 2nd equation

-c-r=-30
<u>c+2r=49 +</u>
0c+1r=19

r=19

sub back
c+r=30
c+19=30
minus 19
c=11

11 chickens
19 rabbits

Write a cosine function for the graph.
Alik [6]

The correct option A: y = -4 cos Ф/4, is the cosine function for the graph.

<h3>Define the term cosine function?</h3>

The ratio between the angle's adjacent leg and the hypotenuse when it is regarded as a leg of a right triangle is a trigonometric function for an acute angle.

  • One of the three fundamental trigonometric functions, cosine is the complement of sine (co+sine) and one of the three main trigonometric functions.
  1. Y=cos(x) has its greatest value when x = 2nπ, wherein n is an integer.
  2. Y=cos(x) has a lowest value for x=  π+2nπ , wherein n is an integer.

For the given graph,

cosine function:  y = -4 cos Ф/4.

In which, -4 is the amplitude (maximum displacement from the x axis).

Negative sign shows, the displacement is taken along negative y-axis.

And,  Ф/4 is the phase angle.

Thus, the cosine function for the graph is  y = -4 cos Ф/4.

What is the inverse of the function f(x) =2x-10
GalinKa [24]
f(x) =2x-10 \\ y=2x-10 \\  \\ x = 2y-10 \\ 2y = x+10 \\ y= \frac{1}{2} x+5 \\  \\  \\ \boxed {f^{-1}(x)= \frac{1}{2} x+5}
