For this case we have to:

Given two lines:

$y_ {1} = m_ {1} x_ {1} + b_ {1}\\y_ {2} = m_ {2} x_ {2} + b_ {2}$

By definition, if both lines are perpendicular to each other, then the product of their slopes is -1. That is to say:

$m_ {1} * m_ {2} = - 1$

ANswer:

The product of the slopes of two perpendicular lines is -1.

Finish labeling the number of elements in the regions in the Venn diagram shown to the right, where the subsets

Virty [35]

Answer:

t=14

v=13

q=12

s=23

w=-4

x=28

Step-by-step explanation:

we know that the universal set =100

so, everything in it must add up to 100

first, from the information given to us,

t= n(A n C)= 14

v=n(B n C)= 13

to find q

we know from our guide that n(A) =40

which means everything inside A will add up to 40

therefore,

q + 7 + 7 + t = 40

and we already know that t = 14

so, that will be;

q + 7 + 7 + 14 = 40

therefore, q = 12

to find s,

we all know that n(B) = 50

which means that everything inside B will be equal to 50

therefore,

s + 7 + 7 + v = 50

and we know that v = 13

therefore,

s + 7 + 7 + 13 = 50

and s will end up to be = 23

to find w,

we know that n(C) = 30

so, everything in C end up to be all equal to 30

therefore,

t + 7 + w + v = 30

from our solution, t = 14, v = 13

so,

14 + 7 + w

$f(x) = -x^2-7x-6$

As $x \to \pm \infty$ , $y \to - \infty$ .

This can be easily verified by looking at the graph (graph of a quadratic equation).

30.

The growth of a population is not linear, it's exponential.

31.

Exponential growth > polynomial, so $y = 3^x$ .

35.

$V(t) = 30\cdot (25)^{\frac{t}{20}}$

The question is asking V(t) for t = 40.

$V(40) = 30\cdot (25)^{\frac{40}{20}} \\~\\V(40) = 30\cdot 25^2 \\~\\V(40) = 30\cdot 625 \\~\\V(40) = 18750$

36.

The point of symmetry of a quadratic equation $y = ax^2+bx+c$ is at its vertice:

$V_x = \dfrac{-b}{2a}$

$V_x = \dfrac{6}{2}$

$V_x = 3$

The line is x= 3.

What is the best estimate for the number of people in line at 7.A.M

Keith_Richards [23]

We have been given the equation

$y=-5.131x^2+31.821x-3.333$

It represents the number of people standing to catch a commuter train x hours after 5 A.M.

Now, in order to find the number of people in line at 7 a.m. , we need to substitute x= 2 in the above equation.

$y(2)=-5.131(2)^2+31.821(2x)-3.333\\y(2)= 39.785 \approx 40$

Therefore, the number of people in the line at 7 a.m. is 40

D id the correct option.
