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

Answer:

13 cm

Step-by-step explanation:

Add up all of the sides and you should get 13.

3 + 3 + 3.5 + 3.5 = 13

Answer: x=8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x−x−1=15

3x+−x+−1=15

(3x+−x)+(−1)=15(Combine Like Terms)

2x+−1=15

2x−1=15

Step 2: Add 1 to both sides.

2x−1+1=15+1

2x=16

Step 3: Divide both sides by 2.

2x /2 = 16 /2

x=8

Answer:

3x-x=15+1

c= 6

Answer:

c = 1 btw can i be brainiest...

Step-by-step explanation:

First, rewrite the left side of the equation and group and combine like terms:

c + (4 − 3c) − 2 = 0

c + 4 − 3c − 2 = 0

−3c + c + 4 − 2 = 0

−3c + 1c + 4 − 2 = 0

(−3 + 1) c + (4 - 2) = 0

−2c + 2 = 0

Next, subtract

2

from each side of the equation to isolate the

c

term while keeping the equation balanced:

−2c + 2 − 2 = 0

−2 − 2c + 0 = −2

−2c = −2

Now, divide each side of the equation by

−2

to solve for

c

while keeping the equation balanced:

−2c - 2 = −2 − 2

−2c − 2 = 1

c = 1

Answer: (x,y) -> (x,-y)

Step-by-step explanation:

If you take any point, for example (-1,1) from the blue shape, you have to multiply the y value by -1 to get to (-1,-1) for the red shape. You can test it out with any point on the two figures.

Also, by looking at it, you can see that it is a reflection over the x axis and a reflection over the x axis always just multiplies the y value by -1.

Answer:

1. Not proportional 2. is proportional. For 3, 4, 5, and 6 just plot them.

Step-by-step explanation:

For 1, y intercept/x intercept is not 0 when you graph, thus not proportional. Number 2 is, thus proportional. For 3, 4, 5, and 6 you would plot them accordingly. So for (-5, -2) Start as 0,0 and go 5 to the left as it's negative, and 2 down as it is also negative. Do the same for others.

Step-by-step explanation:

The right triangle is isosceles, so x = 45° and tan(x) = 1.

__

You can determine tan(x) either from your knowledge of trig function values, or from the fact that the two legs of the triangle are of equal length. The tangent is the ratio of the opposite leg to the adjacent one. When those legs are the same, the ratio is 1.

y=-3+21

Step-by-step explanation: (I can't sketch the graph for you)

First you need to find the slope of the line passing through the points (5,4) and (-7,0). This can be done using the point-slope form of a line.

Point 1: (-7,0)

Point 2: (5,4)

y2-y1=m(x2-x1)

m= (y2-y1)/(x2-x1) = (4-0)/(5-(-7)) = 4/12= 1/3

Now, when two lines are perpendicular, they are negative recopricols. So the slope of the line would be -3.

Since the equation of the line you are trying to find passes through the point (4,9), using point-slope formula again and solve for y.

y-9=-3(x-4)    

y= -3x+12+9

y=-3x+21

Step-by-step explanation:

Llyod used 1/4 chocolates to make 2/3 gallons of chocolate pudding

= 1/4 ÷ 2/3

= 1/4 × 3/2

= 3/8

Therefore the number of pounds needed to make 1/3 of the recipe can be calculated as follows.

= 3/8 × 1/3

= 3/24

= 1/8

Answer:

y = $21,528t

Step-by-step explanation:

Original value of the boat = $23,400

If it looses 8% every year

Amount lost = 8% of 23400

Amount lost after a year = 0.08 * 23400

Amount lost after a year =$1872

Money remaining after 1 year = 23400 - 1872

Money remaining after 1 year = $21,528

To get a function that represents the value y (in dollars) of the boat after t years, we will say;

t year = x

1 year = $21,528

Cross multiply

x *1 = $21,528t

x = $21,528t

Hence the function that represents the value y (in dollars) of the boat after t years is y = $21,528t
