Answer:
the second one
Step-by-step explanation:
Hello There!
The area of a triangle can be found using this formula
![A = \frac{1}{2} (a+b)h](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%28a%2Bb%29h)
where a and b = bases and h = height
The trapezoid shown has the following dimensions
top base = 9cm
bottom base = 14 cm
height = 12 cm
slant height = 13 cm
using this information, we plug in the values into the formula
So ![A = \frac{1}{2} (9+14)12](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%289%2B14%2912)
the equation we created matches the 2nd equation therefore the second one is your answer
Answer:
All real values of x except x = 5
Step-by-step explanation:
The questions asks for the domain of [f/g](x).
That is f(x) / g(x) = [x^2 - 25] / [X-5].
The domain of that functions are all the real except those where the denominator becomes zero.
You find those points by doing X - 5 = 0 => x = 5.
Then, the domain of [f/g](x) is all real numbers except x = 5.
Y = 8x + 40.
Y = score, and x = hours of homework.
Substitute 3 into x
8 x 3 = 24
24 + 40 = 64
So the model predicts a score of 64 for 3 hours of homework.
Hope this helps.
Where are the set of numbers ??
3.14 x 1 = 3.14 square inches
