Answer:
Hello,
Step-by-step explanation:
Loi d'Ohm: U=R*I
a) U=20*0.5=10 (amp)
b) I=U/R=50/0.5=100 (amp)
The answer is C. (2x+5)(2x+5)
By evaluating, we will see that for x = 7 h(x) exceeds g(x).
<h3>
For which value of x does h(x) first exceed g(x)?</h3>
We have:
h(x) = 2*(2)^x
g(x) = 22x - 4
Now we can evaluate both function in the different options:
h(5) = 2*(2)^5 = 64
g(5) = 22*5 - 4 = 106
We can see that for x = 5, h(x) does not exceed g(x), let's try the next one.
h(6) = 2*(2)^6 = 128
g(6) = 22*6 - 4 = 128
So, for x = 6 both functions have the same output, then for x = 7 we will see that h(x) exceeds g(x).
The correct option is B.

Answer:
43.9% people surveyed owned a cell phone
Step-by-step explanation:
Using a venn diagram
Number of people with cell phone = 232
Total number of people surveyed= 528
Percentage of people owning cell phone =232/528 × 100/1 = 43.9%
