4 0

Use the distance formula
sqrt((x2-x1)^2+(y2-y1)^2)
sqrt((-3--1)^2+(0--4)^2)
sqrt(4+16)
sqrt(20) is approximately 4.5

Graph h(x)=7 sin x ?

DENIUS [597]

Answer:

The graph of h(x) is shown below.

Step-by-step explanation:

The given function is

$h(x)=7\sin x$

The general form of sine function is

$f(x)=a\sin(bx+c)+d$

Where, a is amplitude, b is period, c is phase shift and d is vertical shift.

So, the amplitude of the given function is 7, period is 1, phase shift is 0 and vertical shift is 0.

It means the minimum value of function is -7 and maximum value is 7.

Put x=0 in the given function.

$h(x)=7\sin (0)=7(0)=0$

Put $x=-\frac{\pi}{2}$ in the given function.

$h(x)=7\sin (-\frac{\pi}{2})=-7(1)=-7$

Put $x=\frac{\pi}{2}$ in the given function.

$h(x)=7\sin (\frac{\pi}{2})=7(1)=7$

Therefore the points on the function are (0,0), $(-\frac{\pi}{2},-7),(\frac{\pi}{2},7)$ .

The graph of function is shown below.

Solve the following system using a matrix. 7a - b = -1 -4a - 2b = -2

Assoli18 [71]

1. a=-1+b/7 is the right answer. First you had to add by b from both sides of equation, and it gave us, $7a-b+b=-1+b$ . And then simplify, and it gave us, $7a=-1+b$ . Divide by 7 from both sides of equation, and it gave us, $\frac{7a}{7}=-\frac{1}{7}+ \frac{b}{7}$ . Finally simplify, and it gave us the answer is a=-1+b/7 is the right answer.

2. a=-b-1/2 is the right answer. First you had to add by 2b from both sides of equation, and it gave us, $-4a-2b+2b=-2+2b$ . And then simplify, and it gave us, $-4a=-2+2b$ . Next you can also divide by -4 from both sides of equation, and it gave us, $\frac{-4a}{-4}=-\frac{2}{-4}+\frac{2b}{-4}$ . Finally simplify, and it gave us the answer is a=-b-1/2 is the right answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
