Find the derivative of f(x) = negative 8 divided by x at x = 11.
Answers
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

1). what is the area of the rectangle whose length is (x+5) and width (x-5)?
Answers
Answer:
[tex]x^{2}[/tex]-25
Step-by-step explanation:
formula for areas of rectangles= width x height
width=x-5
height=x+5
(x-5)(x+5)= [tex]x^{2}[/tex]-5x+5x-25
since the 5x's cancel out each other
=[tex]x^{2}[/tex]-25 will be the answer
The area of rectangle is [tex](x^{2} -25)[/tex] unit square.
The area of rectangle is product of length and width.
[tex]Area = length*width[/tex]
Given that length is [tex](x+5)[/tex] and width is [tex](x-5)[/tex].
[tex]Area=(x+5)*(x-5)\\\\Area=x^{2} -5x+5x-25=x^{2} -25[/tex]
Hence, the area of rectangle is [tex](x^{2} -25)[/tex] unit square.

Answers
Answer:
61 miles
Step-by-step explanation:
1 / 6 = 1/6
1/6 * 366 = 61
1/6 of 366 is 61
We can check our answer by multiplying 61 and 6 since we divided 366 and 6
61 * 6 = 366
Now that we have checked our answer, we can comfirm that 366 divided by 6 is 61 therefore, our answer is 61 miles in 1 hour
I need help with these questions(see image).
Please show workings.
Answers
Answer:
see explanation
Step-by-step explanation:
(a)
The angle around the centre O of the circle = 360°, then
∠ AOB = 360° - 260° = 100°
Δ AOB is isosceles ( the radii OA and OB are congruent )
The altitude from O bisects ∠ AOB , thus
y = 50°
Since the triangle is isosceles the 2 base angles are congruent, so
x = [tex]\frac{180-100}{2}[/tex] = [tex]\frac{80}{2}[/tex] = 40°
(b)
∠ POR = 360° - 254° = 106°
Δ POR is isosceles (the radii OP and OR are congruent ) , then
the 2 base angles are congruent , thus
a = [tex]\frac{180-106}{2}[/tex] = [tex]\frac{74}{2}[/tex] = 37°
What would you multiply to make the y variable cross out?
-5x + y = -3
3x - 8y = 24
Answers
Answer:
Step-by-step explanation:
-40x + 8y = -24
3x - 8y = 24
-37x = 0
x = 0
0 + y = -3
y = -3
(0, -3)
Answer:
I will show you how to solve for x and y.
Step-by-step explanation:
-5x + y = -3
3x - 8y = 24
You can isolate y in the first equation, and substitute that into the second equation.
so to isolate y in -5x + y = -3, you would add 5x to both sides
this gives you y = 5x - 3
Then substitute this y into the equation below.
3x - 8(5x-3) = 24 (this way, the y variable disappears)
then distribute the 8 into the bracket
3x - 40x + 24 = 24
combine the variables
-37x + 24 = 24
isolate x by moving the constants to one side
-37x = 0
so x = 0
I am not sure if you want the rest, but here it is.
substitute x = 0 into one of the equations.
-5x + y = -3
-5(0) + y = -3
y = -3
