Which function has a vertex at the origin?

Mathematics
1 answer:
dlinn [17]2 years ago
6 0

Answer:

  (d)  f(x) = -x²

Step-by-step explanation:

For the vertex of the quadratic function to be at the origin, both the x-term and the constant must be zero. That is, the function must be of the form ...

  f(x) = a(x -h)² +k . . . . . . . . . . vertex form; vertex at (h, k)

  f(x) = a(x -0)² +0 = ax² . . . . . vertex at the origin, (h, k) = (0, 0)

Of the offered answer choices, the only one with a vertex at the origin is ...

  f(x) = -x² . . . . . a=-1

Jobisdone [24]

Answer:

100

Step-by-step explanation:

Because it would be the most common it would make no sense if any of the other options would represent the value of 2 and 3 if it had it would go over the amount of 200. But if they were represented by numbers 3 would be 60 and 2 would be 40 multiplying by two and ofc 5 would be 100.

What is the sum of interior angles for a nonagon
alexira [117]
Remember your prefixes! They help a lot, because there is a formula for this particular problem. Nonagon refers to a shape with 9 sides. 

The number of triangles a polygon has is represented by the formula: 
(n-2)

Where "n" is the number of sides. If you ever forget what you subtract "n" by think of a triangle. It has 3 sides, so it is only logical that you should only have 1 triangle (subtract by 2). So, what is the sum of the interior angles of a triangle, 180°. So the formula looks like this: 

Sum of Interior Angles = 180°(n-2)
180°(9-2)
180°(7) = 1260° is the sum of interior angles for a nonagon!

3<br>Which is an asymptote of the graph of the function Y = tan(3/4x)​
azamat

Answer:

2)x=-2π/3

Step-by-step explanation:

The following options are missing:

<em>1)x=-4π/3 </em>

<em>2)x=-2π/3 </em>

<em>3)x=3π/4 </em>

<em>4)x=3π/2</em>

<em />

The trigonometric function tan(x) has asymptotes at x = π/2 radian and x = -π/2 radian. Therefore, tan(3/4x) would have asymptotes at:

3/4x = π/2

x = π/2*4/3

x = 2π/3

or

3/4x = -π/2

x = -π/2*4/3

x = -2π/3

Create an equivalent expression for 1.3 cubed over 1.2 raised to the fourth power all raised to the power of negative six. 1.2 r
Oxana [17]

Based on the given parameters, the equivalent expression of [(1.3^3)/(1.2^4)]^-6 is (1.2^[24])/(1.3^[18])

<h3>How to determine the equivalent expression?</h3>

The expression is given as:

[(1.3^3)/(1.2^4)]^-6

Apply the power law of indices to the above expression

[(1.2^4)/(1.3^3)]^6

Next, we expand the exponents using the power law of indices

(1.2^[4 * 6])/(1.3^[3 * 6])

Evaluate the products

(1.2^[24])/(1.3^[18])

Hence, the equivalent expression of [(1.3^3)/(1.2^4)]^-6 is (1.2^[24])/(1.3^[18]) based on the given parameters
