Sin 3pi/4 is angle 135 degrees or 45 degrees below 180 degrees. Hence it's opposite side is 1 and adjacent is 1, implying the hypothenus is sqrt(2). Hence

Sin 3pi/4 = 1/sqrt(2). Now multiply by sqrt(2)/sqrt(2) to get:

[1/sqrt(2).] * [sqrt(2)/sqrt(2)] = sqrt2)/2

Nerissa paid a total of $8 for 4 packs of pencils she purchased from the convenience store. Let p represent the cost of one pack

BARSIC [14]

Answer: 4*p=8

Step-by-step explanation:

<em>You can use inverse operation to answer this equation.</em>

<em>write out you problem: 4 x p =8</em>
<em>The inverse of multiplication is division</em>
<em>you do 4/4 which gives you one but the 4 will cancel itself out</em>
<em>Do 8/4 which gives you 2</em>
<em>under the equation write p = 2</em>
<em>And be sure to line the p up with the p, the equal sign with the equal sign, and the 2 stays where it is ( which should be already lined up with the 8)</em>

Can anyone explain and give answer please?

Ghella [55]

Answer:

slope = - $\frac{1}{19}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 19x + 57 ← is in slope- intercept form

with slope m = 19

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{19}$ ← slope of line w

Due: Today Raven told Micah the perimeter of the swimming pool was 35 feet, the dimension of the pool were 5 ft by 7 ft. Micah s

pychu [463]

Answer: Micah

Step-by-step explanation:

Given

Raven told Perimeter of the swimming pool is $35\ ft$

Micah said Perimeter is $24\ ft$

The actual dimension of the swimming pool is $5\ ft\times 7\ ft$

Perimeter is given by $2(l+w)$

Using this, the perimeter is

$\Rightarrow P=2(5+7)\\\Rightarrow P=2\times 12=24\ ft$

$\therefore$ Micah statement is correct.

What is the slope of the line that passes through the points (4, 9) and (1, 6)?

Aleksandr [31]

a = ( 1 , 6 )

b = ( 4 , 9 )

$slope = \frac{y(b) - y(a)}{x(b) - x(a)} \\$

Now just need to put the coordinates in the above equation :

$slope = \frac{9 - 6}{4 - 1} \\$

$slope = \frac{3}{3} \\$

$slope = 1$

And we're done...♥️♥️♥️♥️♥️
