Answer:
1,260
Step-by-step explanation:
Therefore, 1,260 committees can be formed.
Step-by-step explanation:
PART A: The area of a circle is radius squared times pi. To estimate the radius, you have to divide the area by pi (estimate 3.14) and then find the square root of the quotient
600/3.14=191.0828...
Square root/radius is about 13 sq feet
PART B:
Now use the pi button instead of 3.14 and do the same thing.
Square root/radius is about 16.9 feet
PART C: Since it's the radius squared and you are doubling it again, it would be radius squared times radius squared, or radius to the fourth power...meaning the area would quadruple.
Reasoning is valid. Area if radius was doubled would be about 3589 feet. ROund to 3600, which divided by 900 is 4
Answer:
A
Step-by-step explanation:
becuase the 3 is negtive and the 4/5 so it A
X=<span>−0.786151</span>,<span>0.786151
</span>First you subtract 1 from both sides
<span><span><span><span>x4</span>+<span>x2</span></span>−1</span>=<span>1−1
</span></span><span><span><span><span>x4</span>+<span>x2</span></span>−1</span>=0
</span>Then you use the quadratic formula and you should get your answer of...
<span>
</span><span><span>x=<span>−0.786151</span></span>,<span>0.786151</span></span>
