Answer:
B
Explanation:
Draw the Rhombus
Draw a rhombus.
At the midpoint of the given diagonal, draw a line to the enclosed angle of two of the sides.
The diagonals meet at 90 degrees.
You can use the Pythagorean Theorem to get the third side.
c^2 = a^2 + b^2
c = 10 length of 1 side
b = 8 This is 1/2 of 16. They diagonals meet at their midpoints
a = ?
10^2 = 8^2 + a^2
100 = 64 + a^2
a^2 = 36
a = 6
The area of one right triangle = 6*8/2 = 24
The area of all 4 right triangles = 96
Answer: Germanyyyy
Explanation: Google helped :)
We first need to write the function in standard form.
y = -x^2 - 7x + 18
To find the axis of symmetry, we do -b/2a
The a and b are the coefficients of the x values.
So a would be -1 since -x is same as -1x
Follow that, b would be -7.
Then just plug the values in. - (-7)/2(-1) = -7/2
The axis of symmetry is -7/2
