Answer:
<em>(12, 2)</em> is the original point on the graph of 
.
Step-by-step explanation:
<u>Given:</u>
has a point <em>(3, 6)</em> on its graph.
<u>To find:</u>
Original point on graph = ?.
<u>Solution:</u>
We are given that The point (3, 6) is on the graph of
If we put x = 3 and y = 6 in , it will satisfy the equation.
Let us the put the values and observe:
Now, let us compare the above with the following:
we get y = 2 and x = 12
So, the original point on graph of is <em>(12, 2).</em>
Let the unknown angle be x.
That is
sin x = 4/5
cos x = 3/5
By drawing a right triangle in the first quadrant,
hypotenuse = 5
Adjacent side = 3
opposite side = 4
That is tan x = 4/3
From the calculator,
x = arctan(4/3) = 53 deg (nearest integer)
Answer: 53 deg. (nearest integer)
Answer: 1st train = 364 mph, 2nd train = 356.2
Step-by-step explanation:
Train 1: x + 7.8
Train 2: x
Train 1 + Train 2 = Sum
x + 7.8 + x = 720.2
7.8 + 2x = 720.2
2x = 712.4
x = 356.2
Train 1: x + 7.8
= 356.2 + 7.8
= 364
To find the value of h, you will order the data and then determine if there is enough information to find the missing value knowing that from the beginning of the data to the end is a range of 9.
11, 11, 15, 15, ____ (20)
or
(6)_____, 11, 11, 15, 15
The missing value of h could be 9 or 20.
