Mathematics
1 answer:
vfiekz [6]3 years ago
3 0

Answer:

Vertex(-3,1)

Step-by-step explanation:

We have a graphical representation of our parabola.

Showing both the x axis and the y axis and showing the values of each point of the parabola on it.

As we can see we have some major points like point p = (-4,0)

And point q = (-1,-3)

What I want to point out is that every unit represent a two then half of it represents a one.

So the position of our vertex which is the maximum point on the graph

X axis = -3

Y axis =1

So the point our vertex is located

Vertex(-3,1)

Solve similar triangles solve for x can someone answer please help
zlopas [31]

Answer:

Step-by-step explanation:

ΔABC & ΔADE are similar triangles

\frac{AD}{AB}=\frac{DE}{BC}\\\\\frac{12}{4}=\frac{12}{x}\\

Cross multiply,

12*x = 12*4

x=12*\frac{4}{12}\\

x = 1 * 4

x = 4

Find the Area of the figure
sineoko [7]
The figure is made up of two semi-circles and one triangle

--------------------------------
Find Radius
--------------------------------
Radius = Diameter ÷ 2
Radius = 5 ÷ 2 
Radius = 2.5 ft


Area of the semi-circle = 1/2 πr²
Area of the semi-circle = 1/2 x π x (2.5)²
Area of the semi-circle = 9.82 ft²

Area of the triangle= 1/2 x base x height
Area of the triangle = 1/2 x 6 x 4
Area of the triangle = 12 ft²

Total area = 9.82 + 9.82 + 12 
Total area = 31.63 ft²

--------------------------------------------
Total Area = 31.63 ft²
--------------------------------------------

Find the maximum and minimum values of the function.<br> Y=-cos8x
natka813 [3]

Answer:

A

Step-by-step explanation:

Given a sinusoidal function (sine function or cos function) in the form

y = A Cos (Bx), we can say that A is the amplitude.

<em>Amplitude defines the function's maximum and minimum.</em>

The maximum of this form of function is A and the minimum is -A.

The function given is y = -Cos(8x), so A is -1

Thus, maximum value is 1 and minimum value is -1.

Correct answer is A
