Mathematics
1 answer:
Andreyy893 years ago
7 0

Answer:

Step-by-step explanation:

Number of vertices

3

Variable constraints

a>0 and b>0

Diagonal lengths

(data not available)

Height

b

Area

A = (a b)/2

Centroid

x^_ = (a/3, b/3)

Mechanical properties:

Area moment of inertia about the x-axis

J_x invisible comma x = (a b^3)/12

Area moment of inertia about the y-axis

J_y invisible comma y = (a^3 b)/12

Polar moment of inertia

J_zz = 1/12 a b (a^2 + b^2)

Product moment of inertia

J_x invisible comma y = -1/24 a^2 b^2

Radii of gyration about coordinate axes

r_x = b/sqrt(6)

r_y = a/sqrt(6)

Distance properties:

Side lengths

a | sqrt(a^2 + b^2) | b

Hypotenuse

sqrt(a^2 + b^2)

Perimeter

p = sqrt(a^2 + b^2) + a + b

Inradius

r = 1/2 (-sqrt(a^2 + b^2) + a + b)

Circumradius

R = 1/2 sqrt(a^2 + b^2)

Generalized diameter

sqrt(a^2 + b^2)

Convexity coefficient

χ = 1

Mean triangle area

A^_ = (a b)/24

Write the function for the graph
Kruka [31]

Answer:

Option A is correct.

The function for the given graph is;

f(x)=2\cdot 4^x

Step-by-step explanation:

An exponential function is in the form of y =ab^x ......[1] where a is the initial value and b≠ 0 , b >1 .

Given two points as shown in figure i.e,

let A = (0, 2) and B = (1,8)

Substitute these points in equation [1] we have;

For A = (0,2)

2 = ab^0 = a

⇒ a = 2

and

for B = (1, 8)

8 = ab^1

or

ab = 8

Substitute the value of a=2 in above equation to solve for b;

2b = 8

divide both sides by 2 we get;

b = 4

Then, the function for the graph is, y=f(x)=2\cdot 4^x

Escribe el nombre de algún tipo de ángulo que se forma "Entre Dos rectas Paralelas y una Secante"
blsea [12.9K]

Answer:

We see that opposite angles are two angles between two secant lines (“secant lines” simply means two lines that cross each other) that share a vertex (that is why they are called “vertical” angles). We see also that they are not adjacent (which means next to each other) but opposite each other.

Step-by-step explanation:

Vemos que los ángulos opuestos son dos ángulos entre dos líneas secantes (“líneas secantes” simplemente significa dos líneas que se cruzan) que comparten un vértice (por eso se llaman ángulos “verticales”). También vemos que no son adyacentes (lo que significa uno al lado del otro) sino uno frente al otro.

Find the slope pf the line on the grap (-2,2),(4,0) reduce all fractional answers to the lowest term.
wariber [46]
Hey there! :) 

We're trying to find the slope of the line on the graph (not given, but that's okay). We're given the points (-2, 2) and (4, 0). 

Using the slope equation, we simply just have to plug our points in and boom - there's your slope! 

Slope equation : m = y₂ - y₁ / x₂ - x₁

Now, using our given points, we can very simply plug everything in! :)

Now, in case you didn't know which number aligns with which variable, I'll go ahead and help you out with this. 

x₁ = -2 , x₂ = 4 , y₁ = 2 , y₂ = 0

Now, let's plug and chug!

m = (0 - 2) / (4 - (-2))

Simplify.

m = -2 / 4 + 2

Simplify.

m = -2 / 6

Simplify.

m = -1/3

So, our slope is -1/3.

~Hope I helped!~
