Look at where the arrow is coming from to where it ends
Hi, there.
For this question, we can apply the Pythagorean theorem .
I'm sure you've seen this equation before, and they kind of tried to trip you up with this problem. Trust me, it's easier than it looks. Let's break it down.
Lengths a and b both have the value of 48, which means that the value s in is 48, because the length of the hypotenuse is the same as the length and height squared multiplied by 2.
Plug in the value for c:
Plug in the value for s:
Do the innermost exponents first:
The square root symbol and the power of 2 cancel each other out, so we are left with:
s = , so the hypotenuse is 4608 inches.
Answer:
the probability that system’s failure is due to the radio =
Step-by-step explanation:
From the question given;
Let the mean lifetime of the radio and the mean lifetime of the speaker
we can re-write both expressions as:
and
Let consider to be the variables which are independent to the exponentially distributed mean of
∴
replace the values now; we have:
Thus, the probability that system’s failure is due to the radio =
Your answer is D. y = 36
We can find this by just rearranging the equation firstly:
2 + √4y - 3 = 11
√4y - 1 = 11
√4y = 12
Now we can simplify √4y, because 4 2², so you get 2√y :
2√y = 12
√y = 6
We can now square both sides to get the equation as "y ="
y = 36
I hope this helps! Let me know if you have any questions :)
Answer:
Option C.
Step-by-step explanation:
we have
-----> equation A
-----> equation B
we know that
The solution of the system of equations is the intersection point both graphs
using a graphing tool
see the attached figure
The intersection point is (3,-7) -----> is a common point both lines
The point (1,-3) belong to the line A
The point (6,-6) belong to the line B
therefore
a line includes points 1 comma negative 3 and 3 comma negative 7. A line includes points 3 comma negative 7 and 6 comma negative 6
