Answer:
180 degree rotation about the origin.
Step-by-step explanation:
Note that each coordinate ( x and y) have their sign changed form positive to negative. This is a rotation about the origin of 180 degrees.
Use the compound interest formula
A = P (1 + r/n)^(nt).
Here A = unknown; B = initial amount = $300;
r = rate = 0.0218; n = 2 (2 compounding periods per year); and t = 1/2 (year).
Then A = $300 (1+0.0218/2)^(2*[1/2])
A = $300 (1.0218)^1 or A = $300(1.0218) = $306.54
Differentiation is part of calculus
differentiation basically allows you to find the gradient of tangent
Answer:
-2
Step-by-step explanation:
The equation of the line is written in y=mx+c form, where m is the gradient and c is the y-intercept.
In this case, your m is a -2 and your c is a -3.
Hence the gradient of the line is -2.
