1.You have two ways for solving this.
First, you could use a graphing utility or calculator to graph both functions on the same plane, and given that the functions do not have a
coordinate, the solution of
will be the
coordinate in which the tow graphs intercept (cross each other) as you can see in the picture (1).
The other way is equating the two equations and solve for x:
We know that
and
, so
is equivalent to
. The only thing left is solving the equation for x:
As you can see, both ways gives us the same answer: the solution to the equation
is
.
2. For this one we can repeat the exact same procedures as before:
Graph the functions on the same plane using a graph calculator or graphing utility, and identify the
coordinate in which the two graphs intercept as you can see in the picture (2), or you we can also equate both equations, and solve for
:
And just like before, both ways gives us the same answer: the solution to the equation
is
So, the answer that you should enter in your boxes are:
2 in the first, and
1 in the second one.
Lets say ur points are (1,2)(3,4)
d = sqrt (x2 - x1)^2 + (y2 - y1)^2
u would label ur points
set 1 (1,2)...x1 = 1 and y1 = 2
set 2 (3,4)...x2 = 3 and y2 = 4
or u could label them this way..
set 1 (3,4)...x1 = 3 and y1 = 4
set 2 (1,2)...x2 = 1 and y2 = 2
u have to do (x2 - x1)^2 and (y2- y1)^2....but u can label ur sets of points different. Just make sure u keep ur sets together. Does that make sense ?
T(n)=19-7n
You can use this formula to check if I’m right or wrong by plugging the term # for n...it will show you the # of the term
Answer:
<h3>See below</h3>
Step-by-step explanation:
to figure out the ratios we must figure out the length of <u>hypotenuse</u> first to do so we can consider <u>Pythagoras</u><u> theorem</u> given by
substitute:
simplify squares:
simplify square root:
now recall that,
the ratios with respect to angle w given by
the following ratio with respect to angle X
I believe the formula is lxwxh if so it's 20 x 30 x 4= 2400 i hope this helped
