Marcella would not be able to win the competition because the length of her string is 159.75 feet which is less than 162 feet need to win.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Trigonometric ratio is used to show the relationship between the sides and angles of a right triangle.
Let l represent the length of the string, hence:
sin(28) = l / 75
l = 159.75 feet < 162 feet
Marcella would not be able to win the competition because the length of her string is 159.75 feet which is less than 162 feet need to win.

The combined mean of the 14 people's index finger is: 12.75 cm.
<h3>How to Find the Combined Mean?</h3>
Combined mean = [(mean of first group × number of data of the first group) + (mean of second group × number of data of the second group)] ÷ (number of data of the first group + number of data of the second group).
Given the following:
Mean of first group = 7.8
Number of data of the first group = 7
Mean of second group = 17.7
Number of data of the second group = 7
Combined mean = [(7.8 × 7) + (17.7 × 7)] / (7 + 7)
Combined mean = 178.5 / 14
Combined mean = 12.75 cm.

The initial value here is 100. That means that the pond started out with 100 fish and grew at the rate of 1.05 per day. x is the number of days. Assuming that there is nothing killing the fish that are already in the pond, the domain for the function would be all positive integers greater than 100.
Answer:
Step-by-step explanation:
g(-2)=2(-2)^3+3(-2)^2-3(-2)+4=-16+12+6+4=6
g(-1)=2(-1)^3+3(-1)^2-3(-1)+4=-2+3+3+4=8
it does not change sign ,so there is no real zero between -2 and -1.
