Write as a(x+8)^2-6.
plug in -7 to get -7=a-6; a=-1.
y = -(x+8)^2 - 6
Answer:
i would say 6.50
Step-by-step explanation:
i rounded to the closest tenth
Answer:
1) 16
2) 12
4) 4
5) 0
Step-by-step explanation:
Plug in the value for x in the equation above and solve for y for all 5.
The height is 8 root 3 (sqrt(192)). 8 root 6 = 1/2 * 2 root 2 * x. Simplifying this gives us 8 root 6 = sqrt 2 *x. Square both sides and 64*6=2*x^2 further simplifying gives 192 = x^2, so take the squart root of both sides to get sqrt(192) which is equal to 8 root 3.
Using the distance formula, you can determine the lengths of the sides of the shape. This will help determine if triangles are equilateral, isosceles or scalene; or if quadrilaterals are squares, rectangles, rhombi, or isosceles trapezoids; or if other polygons are regular polygons. The slope formula will tell help you determine if two sides are parallel. In a quadrilateral, this will help you determine if the figure is a parallelogram or a trapezoid.
