Answer:
√
15 +
√
10
Step-by-step explanation:
The answer is above
Try this option:
1. for vertex (2;1) the first equation is: h=-b/2a, it means 2=-b/2a or b=-4a;
2. for vertex (2;1) the second equation is: ax²+bx+c=y, it means 1=4a+2b+c;
3. for point (6;7) the third equation is: ax²+bx+c=y, it means 7=36a+6b+c.
4. using three equation, it is possible to make up the system of equations (and solve it). Details are in the attached picture.
answer:
The graph is in the attachment.
Vectors are orthogonal, when dot product
Vectors
and
are orthogonal.
A = $ 9,845.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 8.25%/100 = 0.0825 per year,
then, solving our equation
A = 4400(1 + (0.0825 × 15)) = 9845
A = $ 9,845.00
The total amount accrued, principal plus interest,
from simple interest on a principal of $ 4,400.00
at a rate of 8.25% per year
for 15 years is $ 9,845.00.
