The quadratic formula is x equals negative b plus or minus the square root of b squared minus four times a times c, all over 2a.
Looking at the equation, we can find the values for a, b, and c
a=7
b= -10
c= -2
So then putting that back into standard form, which is ax^2+bx+c, we know Haley's function in standard form is 7x^2-10x-2
Answer:
(a) ED and AC are distinct lines that intersect <u>True</u>
(b) A and C are distinct points that are collinear <u>True</u>
(c) Another name for plane X is plane F
(d) A, B, C, and <u>D</u> are distinct point that are coplanar
Step-by-step explanation:
The conditions that uniquely define a plane includes one or more of the following properties of an Euclidean space of any given dimensions
1) The location of three non-collinear points
2) A given line with a point that is not on the line
3) Two intersecting and distinct lines.

Answer:
<h3>The answer is option B</h3>
Step-by-step explanation:
Area of a circle = πr²
where
r is the radius of the circle
From the question
Area = 154cm²
To find the radius substitute this value into the above formula and solve for the radius
That's
154 = πr²
Divide both sides by π
We have
Find the square root of both sides
Thats
r = 7.0014086
We have the final answer as
radius = 7.0 cm
Hope this helps you
