Let f be a differentiable function such that f(3) = 2.345 and f' (x) = ln (x^2+ 1). What is the value of f (5)?
Rudik [331]

Use a linear approximation to f(x) centered at x=3:

f(x)\approx f(3) + f'(3)(x-3)

Then

f(5)\approx2.345+\ln(3^2+1)(5-3)\approx6.95

which makes C the most likely choice.

Please help i dont understand how to solve this problem <br> parallel to y=3/2+4 and through (2,-3)
Lesechka [4]
Parallel means it must have the same slope so assuming you meant y=3/2x+4 the slope will remain 3/2

Then you just plug in the coordinates they give you

-3=(3/2)(2)+b
-3=3+b

b=-6 (b is the y intercept)

Final answer: y=3/2x-6

In ANOP, NP is extended through point P to point Q, m_OPQ = (9x – 19)°,
jarptica [38.1K]

Answer:

The values of x and y are x = 6 and y = 9Step-by-step explanation:

MNOP is a parallelogram its diagonal MO and PN intersected at point A

In any parallelogram diagonals:

Bisect each other

Meet each other at their mid-point

In parallelogram MNOP

∵ MO and NP are its diagonal

∵ MO intersect NP at point A

- Point A is the mid-point pf them

∴ MO and NP bisect each other

∴ MA = AO

∴ PA = AN

∵ MA = x + 5

∵ AO = y + 2

- Equate them

∴ x + 5 = y + 2 ⇒ (1)

∵ PA = 3x

∵ AN = 2y

- Equate them

∴ 2y = 3x

- Divide both sides by 2

∴ y = 1.5x ⇒ (2)

Now we have a system of equations to solve it

Substitute y in equation (1) by equation (2)

∴ x + 5 = 1.5x + 2

- Subtract 1.5x from both sides

∴ - 0.5x + 5 = 2

- Subtract 5 from both sides

∴ - 0.5x = -3

- Divide both sides by - 0.5

∴ x = 6

- Substitute the value of x in equation (2) to find y

∵ y = 1.5(6)

∴ y = 9

The values of x and y are x = 6 and y = 9
