Answer:
x=3
Step-by-step explanation:
29-3x=5x+5
29=5x+5+3x
29=8x+5
29-5=8x
24÷8=x
3=x
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
![\frac{ab^2}{ab}=\frac{18}{6}\\b=3\\ab=6\\3a=6\\a=2\\f(x)=2(3)^x](https://tex.z-dn.net/?f=%5Cfrac%7Bab%5E2%7D%7Bab%7D%3D%5Cfrac%7B18%7D%7B6%7D%5C%5Cb%3D3%5C%5Cab%3D6%5C%5C3a%3D6%5C%5Ca%3D2%5C%5Cf%28x%29%3D2%283%29%5Ex)
Answer:
x = (2 i π n)/log(4) + log(2 sqrt(2))/log(4) for n element Z
Step-by-step explanation:
Solve for x:
2 sqrt(2) = 4^x
Hint: | Reverse the equality in 2 sqrt(2) = 4^x in order to isolate x to the left hand side.
2 sqrt(2) = 4^x is equivalent to 4^x = 2 sqrt(2):
4^x = 2 sqrt(2)
Hint: | Eliminate the exponential from the left hand side.
Take the logarithm base 4 of both sides:
Answer:x = (2 i π n)/log(4) + log(2 sqrt(2))/log(4) for n element Z
Answer:
39 shelves needed to build
Step-by-step explanation:
<em>To find the number of shelves needed we need to divide the number of mystery books by 34</em>
<em>We know that. Each shelf can hold 34.</em>
<em>It is given that, There are 1,326 mystery books</em>
<em>So, 1,326/34</em>
39 shelves needed to build
