What is f(–3) for the function f(a)=-2а?-5а+4?
-29
-23
1
37

The answer is 1. f(a) = –2a^2 – 5a + 4. If a = -3, then to find f(-3) we have to substitute a in the general formula. f(a) = –2a^2 – 5a + 4 = -2 * a^2 – 5 * a + 4. Substitute a with -3. f(-3) = –2 * (-3)^2 – 5 * (-3) + 4 = -2 * 9 - (-15) + 4 = -18 + 15 + 4 = 1

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
