Answer:
The value of a = 3
Step-by-step explanation:
Given the function
From the attached graph, it is clear that
at x = 0,
∵
Thus
When x = 0, the y-intercept will be:
From the attached figure, it is clear that
at x = 0, the value of y = 3
so
putting y = 3 in the equation
3 = a ∵
Therefore, the value of a = 3
We know that :
therefore , the correct option is B. 3/4
Answer:
Option (4)
Step-by-step explanation:
If two chords intersect outside the circle, angle formed between the chords will be half of the sum of measures of intercepted arcs.
From the given picture,
95° =
190 = 135 +
= 55°
Therefore, option (4) will be the correct option.
If a function has roots -1 and -5, it must be in the form
We can fix the coefficient a by imposing the passing through (0,-30):
So, the function is
