They answer D 0 < ; y < 7
Function y is a function of cosine transformed by some operations, so cos can take values from interval <-1;1>, which means that this function can take values from interval <-7;-1>. The minimum value is -7. The graph will be very helpuf in this task to understand.
Answer:
8.5 cm
Step-by-step explanation:
original length: x
3.5x = 29.75

x = 8.5 cm
Answer: C. 7x^2+4x-5
Step-by-step explanation:
Add as you would normally. Exponents can look scary but don’t mind them. First add 5x^2 & 2x^2 to get 7x^2. Then do -5x + 9x. An easier way of doing that would be 9x-5x to get 4x. Lastly do 1 -6 to get 5.
Answer:
Step-by-step explanation:
let f(x)=ab^x
when x=1,f(x)=6
6=ab
when x=2,f(x)=18
18=ab^2
divide
