The dy/dx at point (2,8) is 4/3
How to find dy/dx at a point?From the information illustrated, x + 3y^(1/3) = y and point (2,8)
Find the derivative of this equation with respect to x and solve for dy/dx:
x + 3y^(1/3) = y
1 + [3 × 1/3 × y^(-2/3)]dy/dx = dy/dx
1 + [y^(-2/3)]dy/dx = dy/dx
dy/dx - [y^(-2/3)]dy/dx = 1
dy/dx [1- y^(-2/3)] = 1
dy/dx = 1/ [1 - y^(-2/3)]
At point (2,8), x = 2 and y = 8.
Substitute into dy/dx:
dy/dx = 1/ [1 - y^(-2/3)]
dy/dx = 1/ [1 - 8^(-2/3)]
dy/dx = 1/ [1 - 1/4)]
dy/dx = 4/3

An airplane takes off at a speed S of 226 mph at an angle of 18° with the horizontal. Resolve the vector S into components.
Velocity=226mph
Angle made with horizontal= 18°
The vector components would be [tex] 226~sin18° \hat{j} + 226~cos18° \hat{i} [/tex]
The vector components of Speed is [tex]\rm v_x[/tex] = 226 cos 18° and [tex]\rm v_y[/tex] = 226 sin 18°
What is a Vector ?
An parameter that has both magnitude and direction is called a vector.
It is given that
Speed S = 226 mph
Angle = 18 degree with the horizontal
The vector component are
[tex]\rm v_x , v_y[/tex]
here these are x and y components of the vector
V is the magnitude = |v| = 226
The vector component is given by
cos [tex]\rm \theta[/tex] = [tex]\rm v_x[/tex] / |v|
[tex]\rm v_x[/tex] = 226 cos 18°
[tex]\rm v_y[/tex] = 226 sin 18°
Therefore the vector components of Speed is [tex]\rm v_x[/tex] = 226 cos 18° and [tex]\rm v_y[/tex] = 226 sin 18°

What is the sum of 50.249 + 21.3
Answer:
71.549
Step-by-step explanation:
Answer:
The sum of 50.249 + 21.3 is 71.549.
Step-by-step explanation:
50.249 + 21.3 can be written as (50 + 20) + (0 + 1) + (0.2 + 0.3) + 0.049, which makes calculating the sum easier. 50 + 20 = 70, 0 + 1 = 1, 0.2 + 0.3 = 0.5, and you still have a 0.049. Add the numbers all together and you'll get that the sum of 50.249 and 21.3 is 70 + 1 + 0.5 + 0.049 or 71.549.

On a flight,
3/10
of the passengers were children. There were
60 children on the flight. How many passengers were on
the plane?
Answer:
There were 200 passengers on the plane.
Step-by-step explanation:
1. 3/10 of the passengers were children -> 30% of the passengers were children
2. 60 children on the flight 30% of passengers = 60 people
divide by 3 -> 10% of passengers = 20 people
multiply by 10 -> 100% of passengers = 200 people.

If you can buy 48 plaintains for $24 then how many can you buy with $4 ?
Answer:
8 plantains
Step-by-step explanation:
48=$24
x=. $4
192=24x , x= 192÷24= 8
Answer:
8 plantains
Step-by-step explanation:
Cost and number of plantains are in proportion
Number of plantains that can be bought for $ 4 be 'x'
48 : 24 :: x : 4
Product of means = product of extremes
24 * x = 48*4
[tex]x = \frac{48*4}{24}[/tex]
x = 2 * 4
x = 8

What is the volume of the prism, in cubic centimeters?
Answer:
Uhhhhhh, nothing?
Step-by-step explanation:
<2 and <4 are corresponding angles
m<4 = 17x° and m<2 = (9x+40)º
Find x and the measure of each angle.
Answer:
X = 5 u
m∠4 = 85º
m∠ = 85º
Step-by-step explanation:
17x = 9x + 40
17x-9x = 40
8x = 40
x = 40/8
x = 5
m∠4 = (17x)º = (17*5)º = 85º
m∠ = (9x+40)º = (9*5 + 40)º = (45 + 40)º = 85º

Answer:
See below
Step-by-step explanation:
Graphing:we are given two functions
[tex] \displaystyle \begin{cases}f(x) = - x + 5 \\ g(x) = {x}^{2} - 3x + 2\end{cases}[/tex]
where f(x) is a linear function and g(x) is a quadratic function
we want to figure out the solutions of the function
let's graph f(x):
the Black-table is attached
let's graph g(x):
the picture is attached
hence, the graph should be
the graph is attached
solutions stating:so we need solution(s) which satisfy(ies) the both functions
in this case the solution (s) the x coordinate(s) where both functions intercept we get from the graph that both functions intercept at (-1,6) and (3,2)
hence,
x={-1,3}

Step-by-step explanation:
y+12 - 12 = 41 -12
y=29
Answer:
y = 29
Step-by-step explanation:
subtract 12 on both sides to isolate & solve for y:
y + 12 = 41
- 12 -12
=> y = 41 - 12
=> y = 29
