Answer:
An Acute triangle
Step-by-step explanation:
An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°).
Answer:
-12
Step-by-step explanation:
The given expression is

We have to rewrite the given function in the form of
....(i)
then we have to find the product of a,b and c.
The given expression can be rewritten as

Using properties of exponents we get
![[\because \sqrt[n]{a}=a^{\frac{1}{n}}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%5Bn%5D%7Ba%7D%3Da%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D%5D)
![[\because a^ma^n=a^{m+n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5Ema%5En%3Da%5E%7Bm%2Bn%7D%5D)
...(ii)
On comparing (i) and (ii), we get

Product of a,b and c is

Therefore, the product of a,b, and c is -12.
For x-intercepts "b" and "c", a quadratic can be written as
y = a(x -b)(x -c)
You know the x-intercepts, so you can write the equation as
y = a(x +2)(x -3) . . . . . . eliminates the first two answer choices
Substituting (x, y) = (-1, 2), you have
2 = a(-1+2)(-1-3) = -4a
Then dividing by -4 gives
-2/4 = a = -1/2 . . . . . corresponds to the third answer choice
The appropriate selection is
y = -1/2 (x + 2)(x - 3)
3.8+7.6+9.3+31+43+54+62+89+107+119+123+127=775.7
775.7/12=64.64166666666667
So the mean is 64.64
Answer:
This does help you find whether it is a function or not. Since 24 has two outputs, it is not a function.
Step-by-step explanation:
The reason is because for a function to be a function, there must be one input for one out put, it can't have two different outputs.
