Answer:
its b .
Step-by-step explanation:
The first step would be to isolate the square root on the left side. √x-6+2 = 6 √x-6 = -2+6 √x-6 = 4We would have to take away the radical on the left and square the equation. (√x-6)2 = (4)2 x-6 = 16Finally, x -22 = 0 x = 22
What is the problem? I don't understand
Answer:
Step-by-step explanation:
Given that the owner of a motel has 2900 m of fencing and wants to enclose a rectangular plot of land that borders a straight highway.
Fencing is used for 2times length and 1 width if highway side is taken as width
So we have 2l+w = 2900
Or w = 2900-2l
Area of the rectangular region = lw
Use derivative test to find the maximum
So maximum when I derivative =0
i.e when
Largest area = A(725)
=
1051250 sqm is area maximum
<u>Problem</u>
A bag contains 6 blue marbles, 10 red marbles, and 9 green marbles. If two marbles are drawn at random without replacement, what is the probability that two red marbles are drawn?
<u>Work </u>
Probability = no. of favorable outcomes /total no. of outcomes
Probability of getting a blue marble=5/5+6+9=5/20
Probability of getting a red marble=6/20−1=6/19
5/20×6/19
<u>Answer</u>
3/20
So it is C.
