Calculus<br> The following curve passes through (3,1)<br> Using linear lineralization
Novay_Z [31]

Answer:

Option 1.1

Step-by-step explanation:

The linearization of a curve implies the use of calculus to find the local value for the derivative and approximating the function by the use of the formula

F(x) \approx F(x_0) + F'(x_0)(x-x_0)

The function is given in such way that it's much easier to find the derivative by implicit differentiation than isolating any of the variables

2x^2y+y=2x+13

Differentiating with respect to x, we have

4xy+2x^2y'+y'=2

Computing y' in the given point (3,1) we have

4(3)(1)+2(9)y'+y'=2

y'=\frac{2-12}{19}

y'=-\frac{10}{19}

The function will be approximated with the expression

F(x) = 1 -\frac{10}{19}(x-3)

To find the approximate value for x=2.8

F(2.8) = 1-\frac{10}{19}(-0.2)=1.1

The correct value is the option 1.1

The start of the hike, a hiker was at -50 below sea level and climbs a rate of 15 feet per minute
Helen [10]

Answer:

B. -50+15t>5

Step-by-step explanation:

Because the hiker climbs at a rate of 15 feet per minute, the hiker will climb 15t feet in t minutes. Therefore, -50 + 15t would represent where the hiker would be after t minutes. According to the problem, -50 + 15t is greater than 5

Find the radius of the cylinder when volume is 304 cm^3 and height is 10 cm
aleksandr82 [10.1K]

Answer:

<h2>3.11 cm</h2>

solution,

Volume of cylinder=304 cm^3

height=10 cm

Radius=?

Now,

volume = \pi  {r}^{2} h \\ or \: 304 = 3.14 \times  {r}^{2}  \times 10 \\ or \: 304 = 31.4 \times  {r}^{2}  \\ or \:  {r}^{2}  =  \frac{304}{31.4}  \\ or \:  {r}^{2}  = 9.68 \\ or \: r =   \sqrt{9.68}  \\ or \: r =  \sqrt{ {(3.11)}^{2} }  \\ r = 3.11 \: cm

Hope this helps..

Good luck on your assignment..
