F(x)=4-x
g(x)=-4x
(f o g)(x)=f(g(x))=4-(-4x)=4+4x
Answer: (fog)(x)=4+4x
Answer:
Exponential functions are often used to represent real-world applications, such as bacterial growth/decay, population growth/decline, and compound interest
B[0] = 1000
b[n+1] = 1.05*b[n] -10
_____
The fee has the effect of negating the interest earned on the first $200. Effectively, Rita's account balance in explicit form is 200 +(b0 -200)*1.05^n.
Answer:
see explanation
Step-by-step explanation:
Given
2BD = 7BT , then
2(d - b ) = 7(t - b) ← distribute both sides
2d - 2b = 7t - 7b ( add 7b to both sides )
2d + 5b = 7t, thus
2
+ 5
= 7t
+
= 7t
= 7t , thus
t = 
= ![\left[\begin{array}{ccc}3\\5\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%5C%5C5%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Hence T = (3, 5 )
