You can find if lines are parallel or perpendicular by looking at the slope.

The slope is the number who is attached to x in each equation. If they are the same, then lines are parallel. If they are opposite and reciprocal, then they are perpendicular. If they are neither, than it is neither parallel or perpendicular.

A person whose eye level is 20 feet above the ground is looking at a building. The angle of elevation to the top of the building

Inessa [10]

Distance of the person from the building (x)

tan 24 = 20/x => x = 20/tan 24 = 44.92 ft

The height of the building above the height of the person and the distance of the person from the building forms two legs of right angled triangle.

Therefore, if h is the height of the building, then;
tan 31 = (h-20)/44.92
h-20 = 44.92 tan 31
h = (44.92 tan 31) + 20 = 26.99 + 20 = 46.99 ft

Choose the correct measure of an astronomical unit. 9.3 million miles .93 million miles 93 million miles 930 million miles

Genrish500 [490]

By definition, an astronomical unit in miles is given by:
$1 AU = 9.3 * 10 ^ 7 miles
$
As it is in exponential notation, then we must rewrite.
$9.3 * 10 ^ 7 = 93,000,000 miles
$
Therefore, an astronomical unit is:
93 million miles
Answer:
93 million miles

Suppose g is the function g(x) = 2^x and g : {1, 2, 3} ->{1, 2, 4, 8}

Mashutka [201]

Answer:

Step-by-step explanation:

Given that g is a function from g : {1, 2, 3} ->{1, 2, 4, 8}

by the function

$g(x) = 2^x$

i.e. we have $g(1) =2\\g(2) = 4\\g(3) =8$

Range = {2,4,8} Since there is an extra element 1 in the co domain which is not in range , g is not on to

But g is one to one as 1,2,3 have different images.

How are the solutions to the following two equations related m+5=72 <br> m+72=5

EastWind [94]

To see how they are related, let us solve the two equations.

FIRST EQUATION

$m + 5 = 72$

$\rightarrow \: m = 72 - 5$

$\rightarrow \: m = 67$

SECOND EQUATION

$m + 72 = 5$

$\rightarrow \: m = 5 - 72$

$\rightarrow \: m = - 67$

Hence the solutions to the two equations are ADDITIVE INVERSE of each other.
