Answer:
f(-2) = -6
Step-by-step explanation:
In the expression, to get f(-2);
we simply substitute the value of x with -2
We have this as;
f(-2) = -4(-2)^2 + 10
f(-2) = -4(4) + 10
f(-2) = -16 + 10
f(-2) = -6
The function is in polar coordinates.
When this is the case, to pass to rectagular (cartesian) coordinates you use:
x = r cos(theta)
y = r sin(theta)
Then,
x = [2cos(theta) + 2sin(theta)]cos(theta) =
= 2 [cos(theta)]^2 + 2sin(theta)cos(theta) = 2 [cos(theta)]^2 + sin(2theta)
y = [2cos(theta) + 2sin(theta)]sin(theta) =
= 2 cos(theta)sin(theta) + 2[sin(theta)]^2 = sin(2theta) + 2[sin(theta)]^2
Step-by-step explanation:
6x + 2 = 10x + 15
-13 = 4x
x = -13/4
If this is not the answer:
-13/4 = -3,25
Answer:Remember that when you multiply two terms together you must multiply the coefficient (numbers) and add the exponents. Step 2: Combine like terms (if you can). Step 1: Distribute each term of the first polynomial to every term of the second polynomial.
