Answer:
Step-by-step explanation:
This can be represented as exponential decreasing function.
y = a(1 - r)t
a = starting amount
r = rate
t = years
y = 1600(1 - .0725)15
= 1600(.9275)15
= 1600(.32337673)
= 517.40
In 15 years, the forest will shrink in size to 517.40 km2
The answer is D) 0.36. The most preferred gum flavor is spearmint, which had 90 votes, and the total amount of students surveyed is 250. Then, do 90/250, which is 0.36 to find the answer. Hope this helps. By the way, took the test and got it right.
This looks like an ellipse.
Complete the square for y: 9(y²-6y-7)=9(y²-6y+9-9-7)=9((y-3)²-16).
Rewrite the equation:
4x²+9(y-3)²-144=0; 4x²/144+9(y-3)²/144=1; x²/36+(y-3)²/16=1.
Standard equation of an ellipse is (x-h)²/a²+(y-k)²/b²=1, where (h,k) is the origin or centre.
This is the equation of an ellipse with centre (0,3), a=6 and b=4 (semimajor and semiminor axes).
Answer:
y=-1/5x+1
Step-by-step explanation:
divide both sides by 5: 1/5x+y=1
subtract 1/5x so y is alone since slope-intercept has y=mx+b: y=-1/5x+1
