X/0.4 = 10x/4
21/9÷31/6 = 21•6/31•9
so solving the equation gives
X=84/465
Answer:
Step-by-step explanation:
The first one is actually 0 I think. The instantaneous ROC at x=1 should also be 0. The last one should be correct.
Basically, the ROC for the first one is 0 because the y value at the start and end of the interval is the same, so the change is the same. However, for the instantaneous ROC at x = 0, you look at the graph and realize that if you find the derivative at that point, it is 0.
As per given in question, T is mid - point of QP ; so the measures QT and TP are equal.
that is :
Value of x is 6, so correct choice is D
The image is a bit hard to make out, so I'm going to make some guesses. It looks like it says
,
, and
, and you're asked to find
.
You know that
and
are similar, which means their corresponding sides are proportional in length. So there's some constant
such that
To find
, you need to know
and the constant
.
Clearly,
. So, the first equation becomes
Then in the second equation, you have
Answer:-3x+12
