Given:
The coordinates of ∆ABC are A(-3, 2), B(5, 8) & C(11, 0).
To find:
The type of the given triangle.
Solution:
Distance formula:

Using the distance formula, we get





Similarly,





And,





Two sides of the triangle are equal, i.e.,
. So, the triangle is an isosceles triangle.
Sum of square of two smaller side is




Using the Pythagoras theorem, we can say that the given triangle is a right triangle.
Therefore, the correct options are B and F.
Answer:

Step-by-step explanation:
To solve the question we refresh our knowledge of the quotient rule.
For a function f(x) express as a ratio of another functions u(x) and v(x) i.e
, the derivative is express as

from 
we assign u(x)=lnx and v(x)=x^2
and the derivatives
.
Note the expression used in determining the derivative of the logarithm function.it was obtain from the general expression of logarithm derivative i.e 
If we substitute values into the quotient expression we arrive at

Answer:
B, C, D
Step-by-step explanation:
He made a mistake in each product.
-2(-8x) = 16x, not 10 x
-2(-4y) = 8y, not -8y
-2(3/4) = -1 1/2, not - 1/14
Answer:
The equation for slope is m = (y2 - y1)/(x2 - x1)
Step-by-step explanation:
In the above equation, m is the slope. So in order to find it, you need two points on the line. Those points would be (x1, y1) and (x2, y2). You can then stick their values in for the variables and solve for m (which is your slope).
Answer:
Square root of 3 is around 1.7
So point b is the best approximation
