Y=.3x+25(z) z= number of days
y=.3(50)+25(1)
y=15+25
y=40
Answer:
See below
Step-by-step explanation:
Not sure which answer it is because it did not translate well
(2 1/4 ) / (-2/3) = (9/4) / ( -2/3) = 9/4 * (-3/2) = -27/8 <====maybe your answer is in there somewhere?
A= 50.27 because the formula is pi times radius squared
C= 24.13 because the formula is 2 times pi times radius
Imaginary number is one that when squared gives a negative result. ... With imaginary numbers, when you square them, the answer is negative. They are written like a real number, but with the letter i after them, like this: 23iThe letter i means it is an imaginary number.
3.
area=legngth tiimes width
legnth is 10 more than 2 times width
l=10+2w
lw=area=(10+2w)w=10w+2w^2
area=3600
3600=10w+2w^2
so divide by 2
1800=5w+w^2
subtract 1800 from both sides
(note they used x instead of w)
0=w^2+5w-1800
then the facotred form is (w-40)(w+45)=0
0 product property measn if you have xy, then x and or y =0
therefor
w-40=0 and w+45=0
w=40 or -45
discard negative because negative legnth is not possible
explian how solution relates to situation
it is math so it is correct because we represented it corrrectly
the other solution is because of math and eliminate negative legnth becasue tha tis not possible
basically because we represented it correctly
not a very clear quetion to answer
basically 'because it represents the solution so we solved it and it is correct'
