Answer:
When comes to initial value, x is equals to 0.
So x = 0 is substitute into the function.
In Indices Law, any values to the power of 0 will be 1.
So the initial value of function will be :
![f(x) = a( {b}^{x} )](https://tex.z-dn.net/?f=f%28x%29%20%3D%20a%28%20%7Bb%7D%5E%7Bx%7D%20%29)
![f(0) = a \times {b}^{0}](https://tex.z-dn.net/?f=f%280%29%20%3D%20a%20%5Ctimes%20%20%7Bb%7D%5E%7B0%7D%20)
![f(0) = a \times 1](https://tex.z-dn.net/?f=f%280%29%20%3D%20a%20%5Ctimes%201)
![f(0) = a](https://tex.z-dn.net/?f=f%280%29%20%3D%20a)
<span>You ride your bike at an average speed of 8 miles per hour.how many miles can you travel in 1.5 hours? Math. Felicia takes 4 hours to ride her bike 56 miles. She rides at a constant speed during the 4 hour ride.</span>
A:1.23
E: note that 125= 5^3 thus, log_b (125) = log_b(5^3) we can now simplify using the rule log_b(a^c) = c • log_b (a) log_b (5^3) = 3 • log_b (5) since log_b (5) = 0.41, we know that 3 • log_b (5) = 3•0.41 = 1.23
Glad to help :D
Answer:
y = 2x -11
Step-by-step explanation:
The equation of a line that passes through point x1, y1 is given as
y - y1 = m (x - x1)
where m is the slope of the line
Given that the line passes through the point (8,5) and has a slope of 2, the equation of the line
y - 5 = 2 (x - 8)
y - 5 = 2x - 16
add 5 to both sides
y = 2x - 16 + 5
y = 2x -11
