Answer:
Step-by-step explanation:
The exponential function h, represented in the table, can be written as
From table, at x=0, h(x) =10
Put theses values in equation,, we get
Also, for x= 1 , h(x) = 4, so put these values and a=10 in the equation , we get
Put value of a and b in the equation ,
→ Required equation.
Answer:
x = 3.86
a = 5.86
Step-by-step explanation:
From the triangles attached,
By applying cosine rule in triangle 1,
cos(50)° =
cos(50)° =
x = 6cos(50)°
x = 3.86
Now we apply sine rule in the second triangle,
sin(23)° =
sin(23)° =
a = 15sin(23)°
a = 5.86
