Greeley [361]3 years ago
8 0

Answer:

you should use cosine law

it state that the third side lets name it c

c^2=a^2+b^2 -2 × a × b × cos (angle between the 2 sides)

a and b are the 2 sides given

The value missed is 1 min / 60 seconds

<h3>What is unit conversion?</h3>

Units is the conversion between different units of measurement for the same quantity, typically through multiplicative conversion factors.

To convert 720 seconds to hour,

First convert second to minutes divide by 60 and then again convert minutes to hour again divide by 60.

So,

720 seconds * ( 1 minutes /  60 seconds) * ( 1 hour / 60 minutes)

= 12 hours.

Find the equation for the line that passes through the point (1,-3) and that is parallel to the line with the equation 3/2x-2y=-
kondaur [170]

The equation for the line that passes through the point (1,-3) and that is parallel to the line with the equation \frac{3}{2}x - 2y = \frac{-17}{2} is:

y = \frac{3}{4}x - \frac{15}{4}

<h3><u>Solution:</u></h3>

Given that line that passes through the point (1, -3) and that is parallel to the line with the equation \frac{3}{2}x - 2y = \frac{-17}{2}

We have to find equation of line

<em><u>The slope intercept form is given as:</u></em>

y = mx + c

Where "m" is the slope of line and "c" is the y-intercept

Let us first find slope of line containing equation \frac{3}{2}x - 2y = \frac{-17}{2}

\frac{3}{2}x - 2y = \frac{-17}{2}

Rearrange the above equation into slope intercept form

\frac{3x}{2} + \frac{17}{2} = 2y\\\\y = \frac{3x}{4} + \frac{17}{4}

On comparing the above equation with slope intercept form y = mx + c,

m = \frac{3}{4}

So the slope of line containing equation \frac{3}{2}x - 2y = \frac{-17}{2} is m = \frac{3}{4}

We know that slopes of parallel lines are equal

So the slope of line parallel to line having above equation is also m = \frac{3}{4}

<em><u>Now let us find the equation of line having slope m = 3/4 and passes through point (1 , -3)</u></em>

Substitute m = \frac{3}{4} and (x, y) = (1 , -3) in slope intercept form

y = mx + c

-3 = \frac{3}{4}(1) + c\\\\c = -3 - \frac{3}{4}\\\\c = \frac{-15}{4}

<em><u>Thus the required equation of line is:</u></em>

substitute m = \frac{3}{4} and c = \frac{-15}{4} in slope intercept form

y = \frac{3}{4}x + \frac{-15}{4}\\\\y =\frac{3}{4}x - \frac{15}{4}

Thus the equation of line is found out

What is the surface area?<br>18 cm<br>18 cm<br>19 cm​
wariber [46]

Answer:

If it is a rectangular prism (this formula only works with that 3d shape, the answer is 2016 cm²

Step-by-step explanation:

SA=2(hl+hw+lw)

SA=2(18×19+18×18+18×19)

Sa=2(342+324+342)

sa=2(1008)

sa=2016 cm²
