Answer:
x=19
Step-by-step explanation:
The sum of the three anagles is 180
(5x+4)+(x-2)+(3x+7)=180
5x+x+3x+4-2+7=180
9x+9=180
9(x+1)=180
x+1=20
x=20-1
x=19

Let f be the function defined by f(x)=x^3+x^2+x. Let g(x)=f^-1(x), where g(3)=1. What is the value of g'(3)?
Answer:
1/6
Step-by-step explanation:
Given the function
f(x)=x^3+x^2+x
Get the inverse. Let y = f(x)
y = x^3+x^2+x
Replace y with x
x = y³+y²+y
Differentiate with respect to x
1 =3y²dy/dx + 2ydy/dx + dy/dx
1 = (3y²+2y+1)dy/dx
dy/dx = 1/3y²+2y+1
g'(x) = 1/3(g(x))²+2g(x)+1
If x = 3
g'(3) = 1/3(g(3))²+2g(3)+1
g'(3) =1/3(1)²+2(1)+1
g'(3) = 1/3+2+1
g'(3) = 1/6
Hence g'(3) = 1/6
solve for x and the measures for
x=4
Answer:
Below in bold.
Step-by-step explanation:
The angles on the line AC add up to 180 degrees, so:
11x - 8 + 90 + 6x + 2 + 4x + 12 = 180
21x + 96 = 180
21x = 180 - 96 = 84
x = 84/21
x = 4.
<ABD = 11(4) - 8 = 36 degrees.
<EBF = 6(4) + 2 = 26 degrees.
<CBF = 4(4) + 12 = 28 degrees.
