Answer: No

Step-by-step explanation:

This triangle is not a right triangle because:

A right triangle must have one side that is exactly 90°.

A triangle with sides 26, 39, and 43 do not have any sides that total 90.

The answer to your question is no.

Best of Luck!

Let measure angle A equal 40. If angle B complement of angle A, and angle C is a supplemlement of angle B find these measures

uranmaximum [27]

Two angles are complementary when they add up to 90 degrees
m∠B = 90° - m∠A = 90° - 40° = 50°

Two angles are supplementary when they add up to 180 degrees
m∠C = 180° - m∠B = 180° - 50° = 130°

Si el área de una figura rectangular esta dada por A-bxh,¿cual es la siguiente expresiones representa el área de la puerta

stealth61 [152]

Respuesta:

3x² + 5x - 2

Explicación paso a paso:

Dado que :

Área del rectángulo, A = largo * ancho

Dimensión = 3x - 1; x + 2

Área = (3x - 1) * (x + 2)

Área = 3x² + 6x - x - 2

Área = 3x² + 5x - 2

Use a graphing utility to graph the function and the damping factor of the function in the same viewing window.

Bas_tet [7]

Answer:

The function touches the damping factor

at x= $\frac{(4n-3)\pi}{2}$ and x= $\frac{(4n-1)\pi}{2}$

The x-intercept of f(x) is

at x= $n\pi$

Step-by-step explanation:

Given function is f(x)= $e^{-3x} sin(x)$ and damping factor as y= $e^{-3x}$ and y= $(-1)e^{-3x}$

To find when function touches the damping factor:

For f(x)= $e^{-3x} sin(x)$ and y= $e^{-3x}$

Equating the both the equation,

$e^{-3x} sin(x)=e^{-3x}$

$sin(x)=1$

x= $\frac{(4n-3)\pi}{2}$

For f(x)= $e^{-3x} sin(x)$ and y= $(-1)e^{-3x}$

Equating the both the equation,

$e^{-3x} sin(x)=(-1)e^{-3x}$

$sin(x)=(-1)$

x= $\frac{(4n-1)\pi}{2}$

Therefore, The function touches the damping factor x= $\frac{(4n-3)\pi}{2}$ and x= $\frac{(4n-1)\pi}{2}$

To find x-intercept of f(x):

For x-intercept, y=0

f(x)= $e^{-3x} sin(x)$

y= $e^{-3x} sin(x)$

$e^{-3x} sin(x)=0$

Hence, $e^{-3x}$ is always greater than zero.

Therefore, $sin(x)=0$

x= $n\pi$

Thus,

The x-intercept of f(x) is at x= $n\pi$

What is the standard form of the equation y=-5/2x-3 ?

butalik [34]

The standard form of an equation is the form where that equation has no fractions and is written in the form ax + by = c.

To get rid of the fractions in y = -5/2 x - 3, we need to multiply both sides by 2. That makes the equation become:

2y = -5x - 6

Now we need to get it into the form ax + by = c. We can do this by adding 5x to each side.

5x + 2y = -6 is our answer
