The tangent meets the radius at a right angle.
We use (the converse of) the Pythagorean Theorem to check:
Not a right triangle
Answer: FALSE
Answer:
Alrighty so number one is <em>5
z (x + 2y)</em>, and number two is <em>13x + 19y - 34z</em>
The Gradient would be negative therefore making it start by going down then up, making a sad mouth. the x intercepts will be the same. Frankly it just flipped upside down. I remember it like if the gradient is positive then happy smile, if its negative then sad smile. Hope I helped.
Answer: D
<u>Step-by-step explanation:</u>
Vertex form is: f(x) = a(x - h)² + k where (h, k) is the vertex.
f(x) = (x - 3)² - 5
- the vertex is (3, 5).
- "a" is positive (+1), so it points upward.
The only graph that matches is the last one, <em>which I called graph D.</em>
