Answer:
a) y = 16/x²
b) x = 4/5
Step-by-step explanation:
You want the equation for y in terms of x when y is inversely proportional to the square of x, and y is 16 when x is 1. Further, you want the value of x when y is 25.
<h3>(a) Relation</h3>
The wording "inversely proportional to the square" means the form of the equation is ...
y = k/x² . . . . . . where k is the constant of proportionality
The value of k can be found from the given (x, y) pair.
k = x²y = (1)²(16) = 16
The equation is ...
y = 16/x²
<h3>(b) Value of x</h3>
Solving for x gives ...
x = √(16/y)
Then the value of x for y = 25 is ...
x = √(16/25)
x = 4/5
Answer:
9) five hundred and forty three thousand, six hundred and ninety-eight
500,000 + 40,00+ 3,000+ 600+ 90+ 8 = 543,698
10)forty-five million nine hundred eighty-seven thousand one hundred fifty-nine and nine tenths
40,000,000 + 5,000,000 + 900,000 + 80,000 + 7,000 + 100 + 50 + 9 + 0.9 = 45,987,159.9
Try finding the area or perimeter of the triangle then
Answer:
35x^2+29x+6=0
Step-by-step explanation:
volume = length x width x height
all 3 are the same = 2.5
so volume = 2.5 * 2.5 * 2.5 = 15.625 cubic units
