Isosceles
Step-by-step explanation:
It as 3 equal sides and It is upside down
Answer:
the desired range is 0° < angle < 180°
Step-by-step explanation:
If 2x were just slightly less than b, then the angle opposite the base would be just less than 180 degrees.
The larger the value of x, the further the intersection of the two congruent sides is moved away from the base b. The angle between these two congruent sides would approach but never equal zero.
Thus, the desired range is 0° < angle < 180°
The equation of the function in vertex form is y = -(x + 5)² + 4
<h3>What is quadratic equation?</h3>
A quadratic equation is a second-order polynomial equation in a single variable x , ax2+bx+c=0. with a ≠ 0 .
Given that the quadratic function has roots at -3 and -7 and a vertex at (-5,4).
We need to find the equation of the function in vertex form
equation of the function in vertex form.
As per the information given in the question,
The given roots of the function are -3 and -7,
y = a (x + 3) (x + 7)
y = a (x² + 10x + 21)
y = a (x² + 10x + 25 − 4)
y = a (x² + 10x + 25) − 4a
y = a (x + 5)² − 4a
The vertex is (-5, 4),
So, a = -1.
y = -(x + 5)² + 4
Hence, y = -(x + 5)² + 4 is the equation of the function in vertex form

Answer:²
V = (1/3)s³
Step-by-step explanation:
The area of a square base with side length s is A = s². The volume of this pyramid is thus V = (1/3)s²h, where h represents the height. We are told that the height is equal to s. Thus, V = (1/3)s³. This matches Answer C.
