Answer:
D. y = ±√(25 -x²)
Step-by-step explanation:
Subtract x² and take the square root to solve for y.
x² +y² = 25 . . . . . . . given
y² = 25 -x² . . . . . . . . subtract x²
y = ±√(25 -x²) . . . . . take the square root
Answer:
25. 
26. 
Step-by-step explanation:
For 25:
(area of a trapezoid)
(substitute terms)
(collect like terms)
(reduce the fraction by crossing out 2)
(calculate)
For 26:
(equation of area of a circle)
(enter the radius)
(communtative property to reorder the terms)
Answer:
The approximate growth rate of the savings account is 2.5%
Step-by-step explanation:
Given the the function S(x) = 5, 000 * (1.025) ^ (0.7x)
From the function, we can see that part: (1.025). It presents for the growth factor or rate with the formula as:
(1 + r) where r is rate
So we have:
(1 + r) = 1.025
<=> r = 1.025 -1
<=> r = 0.025
In pecentage, we have the rare: 0.025 *100% = 2.5%
So the approximate growth rate of the savings account is 2.5%
Answer:
Option C - 1/81
Step-by-step explanation:
9^(-2) = 1/(9^2) [ Because a^(-m) = 1/(a^m) ]
so, 1/(9²) = 1/81.
Hope this helps you.
