The length can be found using the Pythagorean Theorem...
c^2=a^2+b^2 and in this case:
d^2=(dx^2)+(dy^2)
d^2=(3-7)^2+(12-9)^2
d^2=-4^2+3^2
d^2=16+9
d^2=25
d=5
So the length of AB=5 units.
The answer is
g'(x)=<span>4x^3-10x=0 so </span><span>(4x-10)x=0 it is x= 0 and x= 5/2
</span>
<span>g(0)=4
</span>
<span>g(5/2)=x^4-5x^2+4=11.81</span>
the minimum is M(0, 4)
We will see that the equation has only one solution, so the correct option is B.
<h3>
How many solutions an equation has?</h3>
For an equation of the form:
p(x) = C
Where p(x) is an expression that depends on x, and C is a constant.
The solutions are all the values of x that make the equality true.
For our case, we have:
x = -5
Notice that there is only one value of x that makes the equality true, if we replace x by -5 we get:
-5 = -5
So that is the only solution for the equation, then we conclude that the equation has only one solution, and the correct option is B.

His average pay was:
Answer:
£1350
----------- = £8.44/hr based upon 160 work hours per week
160 hr
Step-by-step explanation:
We must assume that Han works a standard 40-hour week, and that there are 4 weeks in each month. That comes to 160 hours.
Then his average hourly pay rate was
£1350
--------- = £8.44
160 hr
Log(ab) = log(a) +log(b) . . . . . . . . . this is the whole point of logarithms
