Find the derivative of f(x) = negative 8 divided by x at x = 11.
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: (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.
1. Sam bought a camera that originally cost $150.00, but was on sale for 25% off. Sales tax was 6%. How much did he pay for the camera?
A. $121.50
B. $119.25
C. $112.50
D. $156.50
Answer:
B $119.25
Step-by-step explanation:
150 decrease 25% =
150 × (1 - 25%) = 150 × (1 - 0.25) = 112.5
112.5 increase 6% =
112.5 × (1 + 6%) = 112.5 × (1 + 0.06) = 119.25

1c - 20 = 4 - 3c pls help fast in school rn
Answer:
4c-20= 4
+20 +20
4c= 24
/4 /4
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
First come first served brainiest:)
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.

LLoyd used 1/4 of chocolate to make 2/3 gallons of chocolate pudding. If Lloyd's recipe is for 1 gallon of pudding, how many pounds of chocolate will he need to make 1/3 the recipe?
Answer:
1/8
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

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
3x − x − 1 = 15
What is x
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
2x=16
x=16/2
x=8

Answer:

Perimeter of ∆ ABC = Perimeter of ∆ PQR
3x + 9 + 3x + 8 + 3x = 3x + 3x + 4x + 3
9x + 17 = 10x + 3
17 - 3 = 10x - 9x
14 = x
.: x = 14
AB = 3x +9 = 3×14+9 = 42+9 = 51
BC = 3x +8 = 3×14+8 = 42+8 = 50
AC = 3x = 3×14 = 42
PQ = 3x = 3×14 = 42
QR = 3x = 3×14 = 42
PR = 4x +3 = 4×14+3 = 56+3 = 59
it is 212.5°C outside when the temperature starts increasing by 2.5°C each hour. How long will it take for the temperature to reach 25°C?
Answer: 75 hours
Step-by-step explanation:
Assuming you meant decreasing... you find out the span between 212.5 and 25 which is 187.5 and then divide it by 2.5 (which is the change)

Find the value of tan
Х
45°
315
Please help me ASAP please
9514 1404 393
Answer:
1
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.
