Answer:
y = 20 
Step-by-step explanation:
Use the points to find the values of a and b
Using (0, 20 ) , then
20 = a
[ = 1 ] , then
20 = a
y = 20
Using (3, 1280 ) , then
1280 = 20 b³ ( divide both sides by 20 )
64 = b³ ( take the cube root of both sides )
![\sqrt[3]{64}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%7D)
= b , that is
4 = b
Then exponential function is
y = 20.
We are given that Donna knit a total of 12 blankets.
She took 4 months in doing it.
To find the number of blankets in 1 month, take ratio of number of blankets to number of months.
Thus, she knit 3 blankets in 1 months
The answer is the ratio of A's to the number of classes is 7 to 4. That's false. For the statement to be true the ratio should have been 4 to 7.
Ok so here it is
natural numbers: counting numbers like 1,2,3,4,5...
whole numbers: counting numbesr and 0, so 0,1,2,3,4
integers: negative counting numbers and 0, so -3,-2,-1,0,1,2,3...
ratioal numbers, things that can be represented in a/b
percent means parts out of 100 so
x%=x/100
that is a ratioal number
negatives are integers
This answer would be D. x>1
