Y=10.55
Z=17.53
Y: tan37=y/14 ; 14(tan37)=10.55
Z: sin53=14/z ; 14/sin53=17.53
Answer: 9/14 of a pound each day.
Step-by-step explanation:
We can convert the mixed fraction into an improper fraction:
4 1/2 → 9/2
Now we divide by 7, since there are 7 days in a week:
9/2 ÷ 7
When we divide, by a number, it can be placed in the denominator:
9/2*7 = 9/14
There's no other way to simplify it, so that's our final answer.
From 0 years to 1 year:
91-70 = 21
21 / 91 = 0.23 = 23%
From 1 year to 2 years:
70-54 = 16
16 / 54 = 0.29 = 29%
because the percentages are different, it isn't linear. This would be an exponential equation.
The answer is C. because you would multiply the starting population (91) by a percentage of decline raised tot he power of the number of years, as shown in the equation for C.
