F(x)= 2x²+4x-6 and g(x)=2x-2, find each function
1. (f/g) (x) = f(x)÷g(x) = (2x²+4x-6)÷(2x-2)
First factor both top and bottom:
(2x-2)(x+3)÷(2x-2) = x+3
2. f(a + 2) = plug (a+2) in anywhere there is an x in f(x)=2x²+4x-6 -->
2(a+2)^2 +4(a+2)-6 = 2(a^2+4a+4)+4a+8-6, now distribute:
2a^2+8a+8+4a+2, combine like terms
2a^2+12a+10
3. g(a/2) = plug (a/2) in anywhere there's an x in g(x)=2x-2:
2(a/2)-2 = a-2
Answer:
(4+5)+(3+3) because you have eto break up the numbers
The answer is 42.4 because I times it: 5.3 * 18 = 95.39
Answer:
cos(x)=0.6
Step-by-step explanation:
cos(x) represents the horizontal distance of the unit vector
sin(x) represents the vertical distance of the unit vector (0.8)
tan(x) represents the distance on the tangent line from the point to the x-axis
cot(x) represents the distance on the tangent line from the point to the y=axis
Answer:
2.99 cm
Step-by-step explanation:
V= (pi)(r^3)=113.04cm^3
113.04/ (pi) = r^3 = 26.99
r= = 2.99cm
