Answer:
QII
Step-by-step explanation:
I'm thinking that this is supposed to be a quadratic and you forgot the ^2 at the end of the (x + 3). IF this is the case, then the vertex form of a quadratic is
where the h inside the parenthesis with the x- indicates side to side movement and the k indicates up and down movement. Both translations begin at the origin, of course. The important thing to remember here is that the form "x -" is constant. So if our quadratic reflects "x - 3", then it is understood to be "x - (3)" and the movement is 3 units to the right. If the quadratic reflects "x + 3", then it is understood to be "x - (-3)" and the movement is 3 units to the left. Our quadratic, then, is shifted 3 units to the left of the origin and up 2 units, putting us in QII.
If this is what it appears to be, (x + 3) + 2, then it is x + 5 which is a line that has no vertex (which is why I'm thinking it must be a mistyped quadratic!)
Answer:
36.1 meters
Step-by-step explanation:
Since this is a rectangle, the parallel sides are equal to each other, meaning we technically already know all the side lengths.
I'll choose to look at the bottom triangle in this case
30 is already there, and the other leg should be 20. Knowing this, we can plug these into the pythagorean theorem.
20 is A, 30 is B, and the missing side is C
C, the missing side to the nearest tenth is 36.1 meters
Answer:
-30%
Step-by-step explanation:
currently, the perimeter is: 4 + 6 + 4 + 6 = 20 in.
when the width of 4 in is decreased by 3 in, the new width become (4-3) in = 1 in
therefore, the new perimeter is: 1 + 6 + 1 + 6 = 14 in
the change in perimeter is: 20 in - 14 in = 6 in
now, the percent of change in perimeter will be:
%
BUT because this change is a DECREASE, you have to put a NEGATIVE sign before the value to inducate that it's a decrease, so
change in perimeter = -30%
