SOS I'm terrible at math.

<span>y = -5 cos x is a basic (simple) variation of the basic trig function y = cos x.

The given </span>y = -5 cos x could be re-written as <span>y = -5 cos 1x.
Compare this to the most general form:          y =  a cos bx.

Here we see that the coefficient b equals 1.

There is a rule for finding the period of such a function:  Period = 2pi/b.

Since b = 1 here, the Period here is 2pi/1, or simply 2pi.

Please stop saying "I'm terrible with math."  That does not help you at all.  Say, instead, "With just a little help I could understand this just fine."</span>

Isabelle has a five-sided chicken coop in her yard. Each side has an equal length.
Sedaia [141]

Answer:

175 yards

Step-by-step explanation:

Since you are finding the perimeter, it is basically asking you to add up all the given sides, in this case, 5 sides, with the length given, in this case, 35 yards.

35 + 35 + 35 + 35 + 35 = 175

You can also simplify this into 35 x 5 and get the same answer.

Classify is the function as increasing decreasing or constant l
timama [110]

Answer:

Increasing

Step-by-step explanation:

Remember that f(x) is the same as y in slope intercept form y = mx + b.

We don’t have a number for “b” which means the line goes across the origin.

Since 5 replaces m, that is the slope and since it’s positive, it is increasing.

Best of Luck!

Graph the image of this figure after a dilation with a scale factor of 1/3 centered at the origin.
posledela

Answer:

see attached diagram

Step-by-step explanation:

A dilation with a scale factor of \dfrac{1}{3} centered at the origin has a rule:

(x,y)\mapsto\left(\dfrac{x}{3},\dfrac{y}{3}\right).

Then the image of the triangle ABC is triangle DEF(see attached diagram) with coordinates

  • D\left(\dfrac{-3}{3},\dfrac{3}{3}\right)\Rightarrow D(-1,1);
  • E\left(\dfrac{3}{3},\dfrac{9}{3}\right)\Rightarrow E(1,3);
  • F\left(\dfrac{6}{3},\dfrac{6}{3}\right)\Rightarrow F(2,2).
