Formula for compound interest is
Interest = Amount - Principal
Interest = 
- P
Where r = rate in percent
t = time in years
For Jaina,
P = $300
r= 7%
t = 3 yrs
So, Interest = 
- 300
For Tomas
P = $400
r= 4%
t = 3 yrs
So, Interest = 
- 400
So pair of equations for Jaina and Tomas are
Interest = - 300
Interest = - 400
The answer is 9/5 as 3×3 is 9 and you are dividing it by 5.
Answer: 90° counterclockwise rotation about the origin
Step-by-step explanation: Coordinates..
green:
A(-9, 5)
B(-4, 5)
C(-5, -3)
D(-8, -3)
red:
A(5, 9)
B(5, 4)
C(-3, 5)
D(-3, 8)
Answer:
What is the angle for cos, keep question clearly
If angle is 90° then answer is 0
One possible equation for this quadratic would be
y=(x-4)²-1. This is vertex form: y=a(x-h)²+k, where (h, k) is the vertex.
However, this is not the only possible equation. There could be multiple values for a, in front of the parentheses, that we don't know about from the information we are given.
We can also write this equation in standard form (y=ax²+bx+c). First write the squared binomial as the product of two binomials:
y=(x-4)(x-4)-1
Multiply the binomials:
y=x*x-4*x-4*x-4(-4)-1
= x²-4x-4x--16-1
= x²-8x+16-1
= x²-8x+15
Again, this would change depending on what the value of a is in the functoin.
