Ok, well a square is basically two triangles, right? the 45 degree right triangle. if you consider the rules for a 45 degree right triangle, you get: x, x, 2sqrt(x)

plugging in 8, you get the diagonal to be 2sqrt(8) or 4sqrt(2)

Which of the following illustrates the truth value of the given statements?
Ierofanga [76]

Answer:

FT\rightarrow T

Step-by-step explanation:

If p and q are two statements, then you can use the following table to find the value of p\vee q:

\begin{array}{ccccc}p&|&q&|&p\vee q\\ \\T&|&T&|&T\\T&|&F&|&T\\F&|&T&|&T\\F&|&F&|&F\end{array}

If

p: 7 is an even number  - is false, because 7 is not an even number (F)

q: 3 is the square root of 9 - true, because 3 is the square root of 9 (T),

then according to the above table, p\vee q is true.

Correct option

FT\rightarrow T

Answer:

slope (m) = -\frac{3}{2}

Step-by-step explanation:

We can find the slope (m) by using coordinate pairs of any 2 points located along the slope of the line that we have on the graph.

This, let's use the coordinate pairs at:

x = -4, y = 2 (-4, 2) => (x2, y2)

x = 0, y = -4 (0, -4) => (x1, y1)

slope (m) = \frac{y2 - y1}{x2 - x1}

slope (m) = \frac{2 -(-4)}{-4 - 0}

slope (m) = \frac{2 + 4}{-4 - 0}

slope (m) = \frac{6}{-4}

slope (m) = \frac{3}{-2}

slope (m) = -\frac{3}{2}
