The graph of y= sin (x-3pi/2) is the graph of the y = sin(x) shifted in which direction?

Nutka1998 [239]

Answer:

$y=\sin(x-\frac{3\pi}{2})$ is the graph of $y=\sin x$ shifted to the right by $\frac{3\pi}{2}$ units.

Step-by-step explanation:

The given function is

$y=\sin(x-\frac{3\pi}{2})$

The base function of this trigonometric function is $y=\sin x$

In general, the transformation $y=\sin(x-k)$ will shift the graph of the base function, $y=\sin x$ , k units to the right.

Therefore, $y=\sin(x-\frac{3\pi}{2})$ is the graph of $y=\sin x$ shifted to the right by $\frac{3\pi}{2}$ units.

2m - 3 - 5= -m + 10 please help me

valina [46]

$\qquad\qquad\huge\underline{\boxed{\sf Answer☂}}$

Let's solve ~

$\qquad \sf \dashrightarrow \: 2m - 3 - 5 = - m + 10$

$\qquad \sf \dashrightarrow \: 2m + m = 10 + 3 + 5$

$\qquad \sf \dashrightarrow \: 3m = 18$

$\qquad \sf \dashrightarrow \: m = 18 \div 3$

$\qquad \sf \dashrightarrow \: m = 6$

Hence, value of m is 6

Find the diameter of a circle with the known circumference of 314” use the formula d= C

siniylev [52]

The complete formula for circumference is:

$C=\pi d$

Since we know the circumference of the circle is 314 inches, we can then solve for d, the diameter:

$314=\pi d$

Using 3.14 for pi, we get:

$314=(3.14)d$

Then solve for d:

$d=100$

And now we know the diameter of the circle is 100 inches.
