Identify each expression that represents the slope of a tangent to the curve y=1/x+1 at any point (x,y) .

tankabanditka [31]

Answer:

Slope of a tangent to the curve = $f'(x) = \frac{-1 }{(x+1)^{2} }$

Step-by-step explanation:

Given - y = 1/x+1

To find - Identify each expression that represents the slope of a tangent to the curve y=1/x+1 at any point (x,y) .

Proof -

We know that,

Slope of tangent line = f'(x) = $\lim_{h \to 0} \frac{f(x+h) - f(x)}{h}$

We have,

f(x) = y = $\frac{1}{x+1}$

So,

f(x+h) = $\frac{1}{x+h+1}$

Now,

Slope = f'(x)

And

$f'(x) = \lim_{h \to 0} \frac{f(x+h) - f(x)}{h} \\= \lim_{h \to 0} \frac{\frac{1}{x+h+1} - \frac{1}{x+1} }{h}\\= \lim_{h \to 0} \frac{x+1 - (x+h+1) }{h(x+1)(x+h+1)}\\= \lim_{h \to 0} \frac{x +1 - x-h-1 }{h(x+1)(x+h+1)}\\= \lim_{h \to 0} \frac{-h }{h(x+1)(x+h+1)}\\= \lim_{h \to 0} \frac{-1 }{(x+1)(x+h+1)}\\= \frac{-1 }{(x+1)(x+0+1)}\\= \frac{-1 }{(x+1)(x+1)}\\= \frac{-1 }{(x+1)^{2} }$

∴ we get

Slope of a tangent to the curve = $f'(x) = \frac{-1 }{(x+1)^{2} }$

For two independent events, A and B, P(A)equals . 3 andP(B)equals . 2 . a. Find P(Aintersect B). b. Find P(A|B). c. Find

Gnoma [55]

Answer:

a) 0.06

b) 0.3

c) 0.44

Step-by-step explanation:

We are given the following in the question:

A and B are two independent events.

P(A) = 0.3

P(B) = 0.2

a) P(A intersect B)

$P(A\cap B) = P(A)\times P(B) = 0.3\times 0.2 = 0.06$

b) P(A|B)

$P(A|B) = \dfrac{P(A\cap B)}{P(B)} = \dfrac{0.06}{0.2} = 0.3$

c) P(A union B)

$P(A\cup B) = P(A) + P(B) - P(A\cap B)\\P(A\cup B) = 0.3 + 0.2 - 0.06 = 0.44$

Enter the number that belongs in the green box.

lilavasa [31]

the answer is 12.8 because

both of these equations added together make a straight line, or 180 degrees

so we have to put them together: 7x+8x-12=180

and we just solve for x

Divide £700 in the ratio 6:4 (2 marks)

SpyIntel [72]

Answer:

One num = 6x = 6 x 70 = 420

Second= 4x = 4 x 70 = 280

Step-by-step explanation:

6x + 4x = 700

10x = 700

x = 700/10 = 70

One num = 6x = 6 x 70 = 420

Second= 4x = 4 x 70 = 280

I hope im right!
