A= 2 WL+ 2 LH+ 2 HW.
W= width
L= length
H= height
Answer:
y=-2x+15
Step-by-step explanation:
So first we can write it in point slope form.
That is y-y1=m(x-x1)
y1 is the y coordinate
m is the lope
x1 is the x coordinate
This means that the equation is:
y-7=-2(x-4)
We can then convert it to slope intercept form which is
y=mx+b
so
y-7=-2x+8
y=-2x+15
Answer:
Answer: The answer is option B.
Step-by-step explanation:
Here,
We have,



So, it's true; and it lies in quadrant 1 and 4.
The reason according to the "CAST" rule cos theta is in 1st and 3rd quadrant cos theta is positive.
Answer: Height is 5 units.
Step-by-step explanation:
Alright, lets get started.
The area of the triangle is 
The area is given as 30
The base is given as 12
Plugging the values in formula


Dividing 6 in both sides



Hence the height of the triangle is 5 units.........Answer
9514 1404 393
Answer:

Step-by-step explanation:
The domain is the horizontal extent. Since there are arrows on both ends of the graph, the horizontal extent is from -∞ to ∞.
The range is the vertical extent. The graph shows a minimum at y=-2, which value is in the range. Expressed in interval notation, it is [-2, ∞).
Please note that the "end behavior" of y tends to +∞ in for either direction of x.

The graph is "increasing" where it has positive slope, for 3 < x. It is "decreasing" where it has negative slope, for x < 3.
The graph is positive where it is above the x-axis. The points on the x-axis are not part of the "positive" interval(s). You will note there are two intervals where the graph is positive. It isn't difficult to find the answer choice that is a union of two intervals.
The graph is negative where hit is below the x-axis. Again, the points at x=1 and x=5 are not part of that interval, so it is expressed using curved brackets.
