Find tan U. CR=6.3 UC=4.1 RU=7.7

The answer is roughly 1.53658536585366
This value is approximate. Round it however you need to

------------------------------------

Explanation:

RU = 7.7 is the longest side, so it is the hypotenuse. We will not use this as part of the tangent ratio. Recall that tangent is the ratio of the opposite and adjacent sides of the right triangle.

The opposite side of reference angle U is CR = 6.3 since U is nowhere to be found in the letter pair CR. The adjacent side is UC = 4.1 since U is found here.

So,
tan(angle) = opposite/adjacent
tan(U) = CR/UC
tan(U) = 6.3/4.1
tan(U) = 1.53658536585366
This value is approximate. Round it however you need to

7. The graph shows the height, h, in feet, of water
MariettaO [177]

The domain is talking about the "range" of the horizontal axis therefore you will be focusing on the x-intercepts.

The answer will be All non-negative real numbers less than or equal to 18

because the x-intercepts lies at 0 and 18. The answer makes sense because the furthest you can go is 18 ft and the closest you could go is 0 ft. The "all non-negative real numbers" puts a restriction on the least distance it could travel so that means that it stops at 0 ft because if you go any further, you will end up in the negatives and it clearly states "non-negative".

Substitution method <br><br> x-7y=-9<br> -x+8y=10
max2010maxim [7]

Answer:

x = -2, y=1

Step-by-step explanation:

x-7y=-9---------------------equation 1

-x+8y=10-------------------equation 2

From equation 1, make x the subject of formula

x=7y-9----------------------equation 3

substituting x=7y-9 in equation 2,

-(7y-9)+8y=10

Expanding bracket

-7y+9+8y=10

Collecting like terms

8y-7y=10-9

y=1

substituting y=1 in 3

x=7(1)-9

x=7-9

x=-2

How to draw an ray ???
vovangra [49]
A ray starts at one point and goes on forever.

So you just draw a point and a line extending from it with an arrow at the end of the line(the arrow tells you that it goes on forever).
