A herd of zebra currently has 45 members. Based on the available resources, biologists estimate that the size of the herd will i

ncrease at a rate of 7% per year. Which of the following graphs models this relationship, if the x-axis represents years and the y-axis represents number of zebra?

In this case, the zebra growth will increase 7% every year which means the growth will increase every year since its count from total population.  When there is increased in growth, that will make the graph not linear. 
With x-axis represent year and y-axis represent number of zebras, the graph will quadratic graph ( U-shape)

vector u is represented by the directed line segment RS and vector v is represented by the directed line segment OP. if R=(8,-2)
melamori03 [73]

The given points are

R=(8,-2) , S=(11,-6), O=(-3,-9), and P=(0,-13)

To find the value of u and v, we have to perform subtraction of the points . That is

u= RS = =

v = OP =  =

Since we get the same values of u and v , therefore the two vectors are equal .

Solve x2 = 12x – 15 by completing the square. Which is the solution set of the equation?
Nady [450]
For this case we have the following polynomial:
 x ^ 2 = 12x - 15

 The first thing to do is to place the variables on the same side of the equation.
 We have then:
 x ^ 2 - 12x = -15

 We complete the square by adding the term (b / 2) ^ 2 on both sides of the equation.
 We have then:
 x ^ 2 - 12x + (-12/2) ^ 2 = -15 + (-12/2) ^ 2

 Rewriting we have:
 x ^ 2 - 12x + (-6) ^ 2 = -15 + (-6) ^ 2

x ^ 2 - 12x + 36 = -15 + 36
 
(x-6) ^ 2 = 21
 x-6 =+/- \sqrt{21}
 Therefore, the solutions are:
 x = 6 - \sqrt{21}
 x = 6 + \sqrt{21}
 Answer:
 
the solution set of the equation is:
 
x = 6 - \sqrt{21}
 x = 6 + \sqrt{21}
