Answer:
b. y = 3(x+2)^2 + 5
Step-by-step explanation:
The vertex form of a parabola is
y = a(x - h)^2 + k where (h, k) is the vertex.
Here h = -2 and k = 5 so the following could be the required equation\;
y = 3(x+2)^2 + 5
Answer:
143°
Step-by-step explanation:
=90°+53°
=143°
Answer:
slope = -1
Step-by-step explanation:
slope formula: (y2-y1)/(x2-x1)
(1-2) divided by (9-8) = -1/1 = -1
slope = -1
you can switch it up by doing (9-8) divided by (1-2), but it won't make a difference I think.
Answer:
1260.04
Step-by-step explanation:
The formula for compound interest is:
A = P(1+
where A is the final amount, P is the initial principal balance, r is the interest rate, n is the number of times interest applied per time period and t is the number of time periods elapsed. Since the deposit was compounded annually, just like the interest, we can omit the n in the equation.
Applying the formula to question:
800(1+
= 1260.04 (rounded off to nearest cent since it's money)
