4n  -  t<span>he length of a rectangle
4n : 2 = 2n  -  </span>the width of a rectangle

P = (4n + 2n) * 2
P = 12n 

12n : 2 = 6n - the perimeter of the equilateral triangle
P = 3a
6n = 3a
a = 6n : 3
a = 2n - <span>the side length of the triangle - answer.</span>

Which equation could represent the relationship shown in the scatter plot?
KonstantinChe [14]
Choice D : look at where you think the line would be if it followed the direction of the data so that about half of the points fell above the line and half below. The two most important things to note are the slope of the line and y intercept.
This is a negative relationship as the line falls as you read it from left to right. That eliminates choice C. Next, it appears the line of best fit would have a y intercept around 10 on the y axis and then fall down and to the right cutting the data. Note that choices A and B have y intercepts that don't make sense for the data. Choice D does have a y intercept of 10 and a negative slope.

Answer:

5

Step-by-step explanation:

Add the given numbers to the last recorded temp and see what is closest to 100 degrees.

95.5 + 6.5 = 101.5

95.5 + 6.6 = 102.1

95.5 + 5.5 = 101

95.5 + 5 = 100.5


So the closest to 100 degrees would be 5.

Without using a division or multiplication operator and without using iteration , define a recursive method named product that a
Fantom [35]

I will be using the language C++. Given the problem specification, there are an large variety of solving the problem, ranging from simple addition, to more complicated bit testing and selection. But since the problem isn't exactly high performance or practical, I'll use simple addition. For a recursive function, you need to create a condition that will prevent further recursion, I'll use the condition of multiplying by 0. Also, you need to define what your recursion is.
To wit, consider the following math expression 
 f(m,k) = 0 if m = 0, otherwise f(m-1,k) + k 
 If you calculate f(0,k), you'll get 0 which is exactly what 0 * k is. 
 If you calculate f(1,k), you'll get 0 + k, which is exactly what 1 * k is.   
 So here's the function   
 int product(int m, int k) 
 { 
  if (m == 0) return 0; 
  return product(m-1,k) + k;  
}

Novay_Z [31]

The given figure can be drawn as,

From the figure,

\tan \theta=\frac{opposite\text{ side}}{\text{adjacent side}}

\begin{gathered} \tan \theta=\frac{DE}{EC} \\ \tan \theta=\frac{1.5}{2.5} \\ \tan \theta=0.6 \end{gathered}

Since angle of incidence will be equal to angle of reflection, \begin{gathered} \text{tan}Therefore, the height of cactus is 6 m.
