Answer:
y=2500(0.85)^d
Step-by-step explanation:
Seeing as there are no option choices, I shall digress.
Because of a decrease of 15% each day, it means exponential decay. Using the formula y=a(1-r)^x, we have y=2500(1-0.15)^d -> y=2500(0.85)^d
Your function would thus be y=2500(0.85)^d
Base in your question the family plan cost is $55 per month so it means it has a minimum of payment of $55 per month. The variable X is represented as the number of cell phone minutes is used above the plan and Y is the amount of megabytes used above the plan. The best answer to your question is letter C.
It’s true. I hope that helps
<span>Answer: Yes, the 3 foot 3 foot square opening in your ceiling is big enough to insert a 4x8 piece of plywood.</span>
<span>In a 3x3 foot square, we can form two right triangles with same diagonal side or hypotenuse. .</span>
Using the Pythagorean theorem/formula, we can find the length of the hypotenuse or the longest side of the triangle ( c) given the two sides a and b
Substitute values a=3 and b=3 to formula
a^2^+b^2^=C^2^=
3^2^+3^2^=C^2^=
9+9= C^2^
C= square root of 18
C=4.24
<span>A 4x8 piece of plywood can be inserted in a 4.24 opening diagonally.</span>
