Find the line of symmetry equation for the function f(x )=x −2x −3.
andriy [413]

Answer:

x = 1

Step-by-step explanation:

The line of symmetry is defined as the x value of the vertex of a parabola.

To find the vertex of a parabola, we need to convert to vertex form.

Vertex form looks like this:

y=a(x-h)^2+k, where -h is the x value of the vertex and k is the y value of the vertex.

H is also defined as \frac{-b}{2a} where a is the coefficient of x squared and b is the coefficient of the x term.

The coefficient of the x squared term is 1 and the coefficient of b is -2.

Plugging in, we get \frac{-(-2)}{2(1)}, which is equal to 1. This can then be plugged into the equation as

y=1(x-1)^2+k, but k doesn't matter because all we need is the x-term. Now, our x-term is negative h, which is negative negative one, which is positive one. Therefore, our answer is x = 1.

What is the equation, in point-slope form, of the line that is perpendicular to the given line and passes through the point (−4,
Stells [14]
Writing it in perpendicular form is easy as 1, 2, 3.

First you should put it in y = mx + b Form (Slope intercept)

#1: y = x + 7

Simply flip the reciprocals  

#2: y = -x + 7

Identify the middle line for the function.
Ierofanga [76]
The solution to the problem is as follows:

<span>'(t) = 0 gives:
 
-24t + 60 = 0
 
t = 2.5
 
For this t, the second derivative s"(t) = -24 is negative.

And so, s(t) is maximum for t = 2.5.
 
Maximum height is:
 
S = -12(2.5)^2 + 60(2.5) +8 = 233ft
</span>
I hope my answer has come to your help. God bless and have a nice day ahead!

Recall that two angles are complementary if the sum of their measures is 90°. Find the measures of two complementary angles if o
nordsb [41]

Answer:

18° and 72°

Step-by-step explanation:

The angle measures are unknown, so they will be represented with the variable, x.  Since, one angle is 4 times the other, this will be represented with 4x.

To find complementary angles, they are added together and equal 90. So let's create an equation.

x + 4x = 90

Now solve for x.

5x = 90

5x/5 = 90/5

x = 18

One angle is 18°.

Now find the second angle.

4x

plugin 18 for x and multiply

4(18) = 72
