Answer: I think it’s

f ` (x) = - 8 / x²

f ` (11) = - 8 / 121

The value of the derivative at x = 11 is 8/121

The equation of the function is given as:

[tex]f(x) = -\frac 8x[/tex]

Rewrite the above equation as:

[tex]f(x) = -8x^{-1}[/tex]

Using the first principle, the derivative of f(x) is:

[tex]f'(x) = -1 \times -8x^{-1-1}[/tex]

[tex]f'(x) = -1 \times -8x^{-2}[/tex]

Evaluate the product

[tex]f'(x) = 8x^{-2}[/tex]

Rewrite the above equation as:

[tex]f'(x) = \frac{8}{x^2}[/tex]

Substitute 11 for x

[tex]f'(11) = \frac{8}{11^2}[/tex]

[tex]f'(11) = \frac{8}{121}[/tex]

Hence, the value of the derivative at x = 11 is 8/121

What is the correct answer for the mathematics equation 9 + 10 = is that to simple or too hard to answer

9 + 10 would = 19

I hope this helps~

First, we take the first given information: 200 pieces = £76. Since the other unknowns are expressed in pence "p", we convert this amount to "p" = 76 x 100 = 7600p.

The information on "x" and "y" gives us 2 equations:

first:

x pieces + y pieces = 200 pieces (or x + y = 200)

placing "x" in terms of "y" gives us x = 200 - y

in terms of "y": y = 200 - x

50p(x) + 20p(y) = 7600p (or 50x + 20y = 7600)

solving for "x" gives:

x = (7600 - 20y) / 50

substituting y from our first equation gives:

x = (7600 - 20(200 - x)) / 50

x = (7600 - 4000 + 20x) / 50 (distribute - remember to distribute the negative sign)

x = (3600 + 20x) / 50 (simplify)

x = 360/5 + (2/5)x (subtract (2/5)x from both sides)

(3/5)x = 360/5

3x = 360

x = 120 (rulers bought)

substituting into our first equation:

y = 80 (pens bought)

check our solution using the second equation:

50x + 20y = 7600

50(120) + 20(80) = 7600

6000 + 1600 = 7600 (correct)

therefore:

x = 120 rulers Barry bought

y = 80 pens Barry bought

The number of rulers is 120 and the number of pens are 80 in number, bought by Barry.

The four fundamental operations of arithmetic are addition, subtract, multiply, and division of two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.

x + y = 200 pieces

x = 200 - y  (i)

y = 200 - x  (ii)

50(x) + 20(y) = 7600p

Solve the equation for x,

x = (7600 - 20y) / 50

Substitute y from the equation,

x = (7600 - 20 (200 - x)) / 50

x = (7600 - 4000 + 20x) / 50

x = (3600 + 20x) / 50

x = 360/5 + (2/5)x

(3/5)x = 360/5

3x = 360

x = 120 is the number of scales.

Substitute the value of x in the first equation,

y = 80 is the number of pens.

Answer:

A)

At t = 3/2

B)

36 feet

Step-by-step explanation:

The soccer ball is modeled by the function:

[tex]h(t)=-16t^2+48t[/tex]

Where h(t) represents the height in feet of the ball over time t.

Note that this is a quadratic equation.

Part A)

Since this is a quadratic, the maximum height will be reached when the ball reaches its vertex.

So, we will find the x-coordinate of the vertex.

The vertex is given by:

[tex]\displaystyle \Big (-\frac{b}{2a} , h( -\frac{b}{2a} ) \Big)[/tex]

In this case, a = -16 and b = 48. Thus, the t-coordinate is:

[tex]\displaystyle t=-\frac{48}{2(-16)}=-\frac{48}{-32}=\frac{3}{2}[/tex]

The ball will reach is maximum height at t = 3/2.

Part B)

To find the maximum height, we can simply substitute the value back into the function and evaluated. Therefore:

[tex]\displaystyle\begin{aligned} h(\frac{3}{2})&=-16\Big(\frac{3}{2}\Big)^2+48\Big(\frac{3}{2}\Big)\\\\ &=-16\Big(\frac{9}{4}\Big)+24(3)\\ \\ &=-36+72\\\\ &= 36 \end{aligned}[/tex]

The maximum height of the ball is 36 feet.

Answer:

i'm pretty sure that it's y=-2x+1

Step-by-step explanation:

first we solve for the slope of the line:

we have the points (-1,3) and (3,-5). So we write an equation like so:

3 - -5      

-1 - 3    

3/-1 - -5/3. solving that, you get 8/-4, and 8 divided by -4 is -2, so thats our slope.

now all we've got to do is get the y intercept. the way i found it was i graphed the line, put a dot on the points that we have ( (-1,3) and (3,-5) ) and you should

get 1 as the point on the y axis. again, i myself am not a pro or anything so if its not the correct answer i am so sorry. <3

Answer:

Step-by-step explanation:

The first attachment shows the sort of geometry involved. The line of sight from the top of the lighthouse makes a tangent with the earth's surface at the horizon (neglecting optical effects due to the atmosphere).

The hypotenuse of the relevant triangle is (r+h), and the angle is adjacent to the radius, r. Then the cosine relation applies:

  Cos = Adjacent/Hypotenuse

  cos(α) = r/(r+h)

We note that the radius is in km, and the length h is given in meters, so we need to do a conversion to put the numbers in this formula. We don't care so much about the angle itself, but we need its value to find the length of the arc along the earth's surface. That is ...

  s = r·α

so, the distance of interest is found from ...

  cos(α) = 6367/(6367 +0.025)

  r·α = 6367·arccos(6367/6367.025) ≈ 17.84 . . . km

The horizon is about 17.8 km from the observer.

__

The second problem requires we find the height value that makes the distance 32 km.

  32 = r·α = 6367·arccos(6367/(6367 +h))

Dividing by the earth's radius and taking the cosine, we have ...

  cos(32/6367) = 6367/(6367 +h)

  h = 6367 -6367/cos(32/6367) ≈ 6367.0804 -6367 = 0.0804 . . . km

The cliffs must be about 80.4 meters high for it to be possible to see that distance.
