Answer:
Option a is correct
given data in the table represents an exponential function
The possible formula for the function is,
An exponential function is in the form of where a is the initial value and b ≠ 0 , b> 1.
Consider any two points from the table as shown;
(0, 12.5) and (1, 13.75)
Substitute these in [1] we have;
For (0, 12.5)
where x = 0 and f(x) = 12.5 in [1]
12.5 = a
For (1, 13.75)
13.75 = ab
Substitute the value of a =12.5 we have;
13.75 = 12.5b
divide both sides by 12.5 we get;
since, y =f(x)
therefore, we have the following exponential function as:
Say again? I can help, I just need you to restate your question :)
Answer:
Step-by-step explanation:
Step-by-step explanation:
9x+6+5x+90°= 180°
14x+96=180
14x=180-96
14x=84
x= 84/14
x=6
so, <A=5x=5(6)=30°
<B=9x+6=9(6)+6=54+6=60°
<C = 180-(30+60)=180-90=90°
