What are the x-intercepts of y=sin(x)+1

Stella [2.4K]

Answer:

$x = n\pi + ( { - 1)}^{n} \times \frac{3\pi}{2}$

Step-by-step explanation:

We want to find the x-intercepts of

$y = \sin(x) + 1$

At x-intercept, y=0.

$0 = \sin(x) + 1$

$\sin(x) = - 1$

Take sine inverse of both sides to get:

$x = { \sin }^{ - 1} ( - 1)$

$x = n\pi + ( { - 1)}^{n} { \sin }^{ - 1} ( 1)$

The x-intercepts are:

$x = n\pi + ( { - 1)}^{n} \times \frac{3\pi}{2}$

for n being an integer

Find the value of x. X+16 3x-1 6x 5x. It is like a trapezoid on the outside to the left it is x+16 on the bottom right 6x on the

likoan [24]

Answer:

The value of x is 23.

Step-by-step explanation:

Consider the below figure attached with this question.

Form the given figure it is clear that $(x+16)^{\circ},(3x-1)^{\circ},6x^{\circ},5x^{\circ}$

The sum of all exterior angles of a quadrilateral is 360°.

$(x+16)+(3x-1)+6x+5x=360$

On combining like terms we get

$15x+15=360$

$15x=360-15$

$15x=345$

Divide both sides by 15.

$x=23$

Therefore, the value of x is 23.
