Answer:
27,27 and 126
Step-by-step explanation:
Given that the flag of a country contains an isosceles triangle.
Hence two angles would be congruent. Let the congruent angle be x
Now since sum of three angles of a triangle is 180, we have angles as
Since third angle is 45 more than three times, we have
third angle
45 more than three times the equal angle =
So we have
Third angle =
So angles are 27, 27 and 126
Answer:
<h2>D</h2>Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about</h3>first note: it will be more easy if we solve the inequality first
so let's solve it together
so what we get
we get that x is greater than 12
<h2>so the answer would be d</h2>Answer:
The correct options are:
Option B) is never zero.
Option F) When x=0, y≠0
Step-by-step explanation:
Consider the provided function.
When we substitute x=0 in above function we get:
When we substitute x=-1 in above function we get:
When we substitute x=1 in above function we get:
The above function is exponential function which does not pass through the origin and the range of the function is a positive number.
The graph of the function is shown in figure 1.
Now consider the provided options.
Option A) is always greater than or equal to 1.
The option is incorrect as the value of the function is less than 1 for negative value of x.
Option B) is never zero
The option is correct.
Option C) When y=0, x=0
The option is incorrect.
Option D) When x=0, y=4
When x=0 the value of y is 1.
Thus, the option is incorrect.
Option E) is zero when x=0
When x=0 the value of is 1.
Thus, the option is incorrect.
Option F) When x=0, y≠0
The option is correct as 0≠1.
