Answer:

2,-1.5

Step-by-step explanation:

To find the midpoint of a line segment, take the average of the x coordinates and y coordinates of the two points that make it up.

\frac{2+2}{2} ,\frac{4+(-7)}{2}

=\frac{4}{2} , \frac{-3}{2}\frac{4}{2} , \frac{-3}{2}

=2,-1.5

Here's the answer for you

Functions f(x) and g(x) are shown below:
AlekseyPX
Consider f(x) = -4(x - 6)² + 3
This is a parabola with vertex at (6, 3).
Because the leading coefficient of -4 is negative, the curve opens downward, and the vertex is the maximum value.

Answer: Maximum of  f(X) = 3

Consider the function g(x) = 2 cos(2x - π) + 4
The maximum value of the cosine function is 1.
Therefore the maximum value of g(x) is
2*1 + 4 = 6

Answer: Maximum of g(x) = 6

What’s the area of this triangle?
tankabanditka [31]

Answer:

26.75

Step-by-step explanation:

There are two ways to do this. You can use the base*height/2 formula for the area of the triangle, or use the complex formula of determining triangle area without height.

The first is A=(b*h)/2

In this case you need to find the height using a²+b²=c²

Take your base (7.6) and divide it by 2 this will give you the bottom side of your triangle (3.8) now plug this, and the side value of 8 into the formula. Remember c is the hypotenuse (diagonal side) and x is the height.

3.8²+x²=8²

14.44+x²=64

x²=49.56

x=7.039 -now you have the height for the triangle and can use this to find the area

A=b*h (in this case we dont have to divide by two since we need two triangles because we split the original in two to find the base of 3.8)

so it's 3.8*7.039=26.75

(If you need more help look up Silicon Valley High school's video titled, "How to find the area of a triangle (without the height)"

It will teach you the formula A=\sqrt{s(s-a)(s-b)(s-c)} which teaches you to find the area of any triangle when all you are given is three sides

Log base 2 (1/4) ...?
liubo4ka [24]
Log ( base 2 ) ( 1 / 4 ) =
= log ( base 2 ) ( 2 ^(-2 ) ) =   
= - 2 log ( base 2 ) 2 =    ( because : log x^n = n log x )
= ( - 2 ) * 1 =    ( because:   log (base x) x = 1 ) 
= -  2
