Answer:
No, they're not
Step-by-step explanation:
If two triangles have equal angles we can say they are similar, as u can see it doesn't apply for those triangle.
Answer:
Options A
Step-by-step explanation:
Properties of the graph given for the function 'g',
y-intercept of the function 'g' → y = -4
Minimum value of g(x) → y = -4 (Value of the function at the lowest point)
Roots of g(x) → x = -2, 2
At x = 4,
g(4) = 11
Another function is,
f(x) = -x² - 4x - 4
= -(x² + 4x + 4)
= -(x + 2)²
Properties of the function f(x) = -(x + 2)²,
y-intercept (at x = 0) of the function 'f',
y = -(x + 2)²
y = -4
Since, leading coefficient of the function is (-1) therefore, graph will open downwards and the maximum point will be its vertex.
Maximum value of the function 'f' = Value of the function at the vertex
Coordinates of vertex → (-2, 0)
Therefore, maximum value of 'f' = 0
Roots (at y = 0) of the function 'f' → x = -2
At x = 4,
f(4) = -(4 + 2)²
= -36
Therefore, Options A will be the correct option.

Answer:
b) irrational
Step-by-step explanation:
a² = 7/36 . . . . . . given
a = (√7)/(√36) = (√7)/6
7 is not a perfect square integer, so √7 is irrational. Dividing it by an integer does nothing to make 'a' rational. <em>a</em> is irrational.
