Answer:
Quadratic.
Step-by-step explanation:
Both linear and exponential equations are monotone increasing or monotone decreasing functions.
This means that, as the input increases, the output will only increase or only decrease, but never both.
Here for our data, we can see that first we have:
x = -8
y = 13
Then x increases to x = -6, and y decreases to y = 9
Then x increases to x = -4 and y increases to y = 13
Then this function is not monotone increasing nor monotone decreasing, so the data can not describe a linear nor an exponential function.
Then the correct option is quadratic.
Answer:
125g
Step-by-step explanation:
You can find the mass of the yoghurt by dividing the mass of the fruit and the yoghurt by the sum of the ratio,(2+5), then multiplying that value by 5.
You just need to do 12 1/5 ÷ 1 4/5.
To do this, first convert both fractions to improper fractions or topheavy fractions.
12 1/5 -
15 × 5 is 60, 60 + 1 is 61 so 12 1/5 = 61/5
1 4/5 -
1 × 5 is 5 and 5 + 4 is 9. 1 4/5 = 9/5
To divide fractions, you do keep, chang, flip (keep the 1st fraction, change the ÷ to ×, and flip the 2nd fraction)
the question starts as 61/5 ÷ 9/5 and becomes 61/5 × 5/9
multiplication in fractions is literally just numerator × numerator / denominator × denominator.
61 × 5 is 305. 5 × 9 is 45. the fraction is 305/45.
however, we need a whole number. 305/45 converted into a decimal is 6.7777778 (6.7 recurring). obviously you can't put a fraction of a book onto a shelt, so you round it down to the nearest whole number, which is 6.
final answer: 6
