Answer:
1. 110 degrees.
2. 276 students.
Step-by-step explanation:
1. Converting the ratios to fractions:
3 + 4 + 11 = 18 so the largest angle is 11/18 of 180 degrees.
Answer is 180 * 11/ 18 = 110 degrees.
2. That would be 460 * 36 / 60
= 276 students.
Answer:
-2
Step-by-step explanation:
5 to the 2nd power is 25 and a number to a negative power is 1/number^power
<span>Multiply equation A by 2. x+z=6 If you replace the z with the 2, you can add whatever the amount x is to get 6!</span>
Hey the awnser is 20156 lol just kidding u Figueroa out lol ok
Yay, derivitives
I'mma ignore that x is the shorter side because I don't know which one has to be shorter yet
we need to find the max area
but with 3 sides
area=LW
let's say the sides are z and y
zy=area
and the relatiionship between them is
hmm,
z+2y=1200
because one side has no fencing
so
z+2y=1200
solve for z
z=1200-2y
sub for z in other
(1200-2y)(y)=area
expand
1200y-2y²=area
take derivitive
1200-4y=dy/dx area
max is where dy/dx goes from positive to negative
solve for where dy/dx=0
1200-4y=0
1200=4y
300=y
at y<300, dy/dx<0
at y>300, dy/dx>0
so at y=300, that is the max
then
z=1200-2y
z=1200-2(300)
z=1200-600
z=600
so then
z=600
y=300
300<600
so the shorter side would be y
so then we see our choices and noticed that
erm
I think it is f(x)=1200x-2x²
takind the derivitive yeilds none of the others
so ya, you are right
