Answer:
-25
Step-by-step explanation:
(1) y = -2x²
(2) y = 2x² + k Subtract (1) from (2)
0 = 4x² + k Subtract 4x² from each side
k = -4x²
The parabolas are <em>symmetrical about the y-axis.</em>
Segment AB = 5, so x = +2.5 and x = +2.5.
k = -4(±2.5)² = -4 × 6.25 = -25
1.79(4.05 + 2.78) is the answer i had this question and this is the right answer I hope it helps

Answer:
$1790.99
Step-by-step explanation:
<u>Given</u>:
$1625 is invested at an annual rate of 1.95% compounded quarterly for 5 years
<u>Find</u>:
the ending balance
<u>Solution</u>:
The compound interest formula applies.
FV = P(1 +r/n)^(nt) . . . Principal P at rate r for t years, compounded n per year
FV = $1625(1 +0.0195/4)^(4·5) = $1625(1.004875^20) ≈ $1790.99
The account ending balance would be $1790.99.
