To solve for z, you have to divide both sides by 10.
2/10 = 10/10z
1/5 = z

The answer is B. 1/5.

Hope this helps =)

serious [3.7K]

Set f(x)=2x^3-3x^2+2. Find the tangent line \ell_1(x) to f(x) at the point when x=x_1:

f'(x)=6x^2-6x\implies f'(x_1)=12 (slope of \ell_1)

\implies\ell_1(x)=12(x-x_1)+f(x_1)=12(x+1)-3=12x+9

Set x_2=-\dfrac9{12}, the root of \ell_1(x). The tangent line \ell_2(x) to f(x) at x=x_2 has slope and thus equation

f'(x_2)=\dfrac{63}8\implies\ell_2(x)=\dfrac{63}8\left(x+\dfrac9{12}\right)-\dfrac{17}{32}=7x+\dfrac{151}{32}

which has its root at x_3=-\dfrac{151}{224}\approx-0.6741.

(The actual value of this root is about -0.6777)

The larger of two numbers is 4 more than the smaller the sum of the two numbers is 74
lisabon 2012 [21]

Answer:

y = 35    x = 39

Step-by-step explanation:

Let large no = x and small no = y

According to the question,

x = 4 + y ------ (1)

x + y = 74 -------- (2)

Substituting (1) in (2)

( 4 + y ) + y = 74

4 + 2y= 74

2y = 74 -4

y = 70 / 2 = <u>35</u>

x = 4 + y

  = 4 + ( 35 )

   = <u> 39</u>

What is the inverse of f (x) = x-8/3
liq [111]

Answer:

Step-by-step explanation:

Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=3√x+8 f - 1 ( x ) = x 3 + 8 is the inverse of f(x)=(x−8)3 f ( x ) = ( x - 8 ) 3 .
