Answer:
Step-by-step explanation:
every equilateral triangle is isosceles, but not every isosceles triangle is equilateral
6*5= 30 fingers, so tim would say there are 30 fingers.
Answer:
1) (9, 75+360n)
2) (−9, 255+360n)
Step-by-step explanation:
(9, 75) is same as (9, 75 + 360)
so it would be (9, 435)
It can also be expressed as (-9, 75 + 180 degrees)
so (-9,255) degrees
In general, (9,75+360 n) for n≥0 represents half of the possible ways of representing the point : (9,75)
The statements true about the the function f(x) = 2x2 – x – 6 are-
- The vertex of the function is (one-quarter, negative 6 and one-eighth).
- The function has two x-intercepts.
<h3>What is vertex of parabola?</h3>
The vertex of parabola is the point at the intersection of parabola and its line of symmetry.
Now the given function is,
f(x) = 2x^2 – x – 6
Also, it is given that the vertex is located at (0.25, -6) and the parabola opens up, the function has two x-intercepts.
Comparing the given function with standard form,
f(x) = a x^2 bx + c
By comprison we get,
a = 2
b = -1
c = -6
Now, x-coordinate of vertex is given as,
x = -b/2a
put the values we get,
x = -(-1)/2*2
or, x = 1/4
Put the value of x in given function, so y-coordinate of the vertex is given as,
f(1/4) = 2(1/4)² - 1/4 - 6
= -49/6
= -6 1/8
Hence, The statements true about the the function f(x) = 2x2 – x – 6 are-
- The vertex of the function is (one-quarter, negative 6 and one-eighth).
- The function has two x-intercepts.
