Range is the value of y
f(x)=-x²+5
when x=-1, f(x)=-(-1)²+5=4
when x=2, f(x)=-(2)²+5=1
so 1<y≤4
the second piece: f(x)=2x-3
when x=2, f(x)=2(2)-3=1
when x=5, f(x)=2(5)-3=7
so 1≤y<7
union of the two parts of y: 1≤y<7
[1,7) is the answer.
Answer:
96.2*10^5 gallons
Step-by-step explanation:
gallons of milk produced by 1 cow = 2.6×10^3
No. of cows with local dairy farm = 3.7×10^3
Total of gallons of milk produced by farm = gallons of milk produced by 1 cow * No. of cows with local dairy farm = 2.6×10^3 * 3.7×10^3 = 9.62*10^6
we have to write it in standard form = 96.2*10^5 gallons
i can be also written as = 9,620,000 Gallons.
9.62 Million Gallons of milk is produced by local dairy farm Yearly.
Answer:
A. Unit rate.
Step-by-step explanation:
We have been given a statement and we are supposed to choose the correct option for our given statement.
Statement:
A constant of proportionality can also be considered a(n) <u> </u> .
Since we know that constant of proportionality represents the amount by which two proportional quantities vary.
Two quantities are directly proportional, when they are in form
, where k represents the constant of proportionality.
We can represent this proportion also as: 
Since k represents the quotient of y and x, so the value of k represents the unit rate for two quantities y and x, therefore, a constant of proportionality can also be considered an unit rate.
Answer:
Work backwards to solve this problem.
If he ends with 32 cookies, then subtract 12. That gives 20 cookies. 20*2 is 40, so now he has 40 cookies.
Answer:
A
Step-by-step explanation: Well 15:30 I would think is just 1:2 so looking for another ratio like that there's only one other answer. 3:6 15 is half of 30 and 3 is half of 6.
