Answer:

q = log4 / log0.53

q = -2.189

Step-by-step explanation:

(0.53)^q = 4

Taking log of both sides!

q log 0.53 = log 4

q = log 4 / log 0.53

q = 0.602 / -0.275

q = - 2.189

This can be checked to confirm correctness.

Substituting q = -2.189

(0.53)^ -2.189 = 1/ 0.249

= 4.01 Proved!

(Note that the "1" is because of the negative sign)

What is the value of h in this graph ?<br> F(x)= |x - h|
Misha Larkins [42]

Answer:

h=4

Step-by-step explanation:

We know that the vertex(lowest point) of |x-h| is (h, 0).

By inspection, we can see that the vertex of the graph is (4, 0).

So, the lowest point of F(x)=|x-h| is (4, 0), which means \boxed{h=4}
