The derivative of function y =eu is dy/dx = dy/du × du/dx
what is derivative in math?Derivative refers to the rate of change of a variable with respect to any independent variables.
What is chain rule for differentiation?The function that has such a differentiable element which is also a function of other variable is termed as composite function. The method of differentiating composite function is called chain rule for differentiation.
In the above question, y is a composite function as y is a function of u and at the same time u is a function of x.
given, y =eu, where u is differentiable function of x, let u = g(x)
now, y =eu is differentiated using chain rule and we get dy/dx = dy/du×du/dx
hence, the derivative is dy/dx = dy/du×du/dx

Answer:
x = 40°
y = 35°
Step-by-step explanation:
Let us take two triangles ∆ABC and ∆ADE
We know that, in a triangle the sum of all angles is equal to 180°
So,
For the traingle ABC
m∠A = 80°m∠B = 60°m∠C = x°Now,
m∠A + m∠B + m∠C = 180°
80° + 60° + x° = 180°
140° + x° = 180°
x° + 140° - 140° = 180° - 140°
x = 40°
For the triangle ADE
m∠A = 80°m∠D = 65°m∠E = y°Now,
m∠A + m∠D + m∠E = 180°
80° + 65° + y° = 180°
145° + y° = 180°
y° + 145° - 145° = 180° - 145°
y = 35°
Thus, The value of x and y is 40° and 35° respectively

write an equation for the graph shown in the form $y=ax b.$
The required straight equation will be y = -0.5x + 27.5 passes through the points (-5, 0) and (5, 2).
What are equations in a straight line?
A straight line's equation is given by y=mx+c, where c is the height at which the line intersects the y-axis (often referred to as the y-intercept) and m is the gradient.
According to the given graph,
We can see two points are (-5, 0) and (5, 2)
The linear equation will be: y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]
Here
x₁ = -5, y₁ = 0
x₂ = 5, y₂ = 2
⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₂]
Substitute values in the equation, we get
⇒ y - 0 = (2 - 0)/(8-4)(x-(-5))
⇒ y - 30 = (2)/(-4)(x + 5)
⇒ y - 30 = -1/2(x + 5)
⇒ y = (-1/2)x - 5/2 + 30
⇒ y = -0.5x + 27.5
Thus, the required equation will be y = -0.5x + 27.5 passes through the points (-5, 0) and (5, 2).

The length of the ladder is approximately 3 m. The correct option is the first option 3
Calculating the length of a ladderFrom the question, we are to calculate the length of the ladder.
From the given information,
The ladder makes an angle 20° with the ground
and
The foot of the ladder is 3 m from the wall
This scenario gives a right triangle where the hypotenuse is the ladder and the adjacent is the distance of the foot of the ladder from the wall.
Let the length of the ladder be x
Thus,
Using SOH CAH TOA

evaluate √24−x when x = 6. write the answer in simplified radical form.
Given √24−x when x = 6 in simple radical form is 3*√2.
What is radical form?Simply put, simplifying a radical eliminates the need to find any further square roots, cube roots, fourth roots, etc.
Additionally, it entails eliminating any radicals from a fraction's denominator.
The square root of 2 or root 2 is represented using the square root symbol √ and written as √2 whose value is 1.414.
So, we have:
√24−x when x = 6
Thus we must now calculate the square root of 18.
The square root, if you're allowed to use a calculator, is 4.242.
If not, however, let's come as close as we can:
√(9 * 2)
Since 3 is the square root of 9:

The value of ∠WXY = 20.
What is Exterior angle theorem?
The exterior angle theorem describes the connection between the two remote angles in a triangle and the external angle created by an extended side outside the triangle.
Given: Measure of angle YWX = (3x + 17) °
Measure of angle WXY = (3x + 2) °
Measure of angle XYZ = (10x − 5) °
Therefore, m∠XYZ = m∠YWX + m∠WXY (exterior angle theorem)
⇒ (10x − 5) ° = (3x + 17) ° + (3x + 2) °
Solve for x,
⇒ 10x - 5 = 3x + 17 + 3x + 2
⇒ 10x - 6x = 17 + 7
⇒ 4x = 24
⇒ x = 6
∴ ∠WXY = (3x + 2) = 18 + 2 = 20
Hence, value of ∠WXY = 20.

An athlete runs 200 metres race in 24 seconds. what is his speed in km/h
Answer:(29.85km/h)
Step-by-step explanation:
1000m=1km
200m=x [x=(200m/1000m)x1km]
x=0.2km
3600second= 1 hour
24 seconds =b [b=(24s/3600s)x1 hour ]
b=0.0067(in 2 decimal place)
velocity in km/h will be
0.2km/0,0067secs
=29.85(in 2 decimal place)
Answer:
speed = 30 km/h
Step-by-step explanation:
We are told that a 200 metres race is run by an athlete in 24 seconds. The question then asks us to calculate the athlete's speed in km/h.
To do this, let's first convert the given data into the required units:
• Converting from metres to kilometres:
To convert from 200 metres to kilometres, we have to divide it by 1000:
200 m = 200 m ÷ 1000 m/km
= 0.2 km
• Converting from seconds to hours:
To convert 24 seconds to hours, we have to divide it by 3600:
24 s = 24 s ÷ 3600 s/h
= [tex]\frac{24}{3600}[/tex] h
Now that we have the data in the appropriate units, we can use the following formula to calculate speed:
[tex]\boxed{\mathrm{speed = \frac{distance}{time}}}[/tex]
⇒ speed = [tex]\mathrm{\frac{0.2 \ km}{24/3600 \ h}}[/tex]
⇒ speed = 30 km/h
Therefore, the speed of the athlete is 30 km/h.

2 5 3 7 10 0 6 8 5 11 3 1
a) We have to find the sample mean and the standard deviation (round to two decimal places).
The sample mean;
X = 2+5+3+7+10+0+6+8+5+11+3+1/12
X = 61/12
X = 5.0833
Now the standard deviation
SD = √[{x(1)-X)^2+(x(2)-X)^2…………….(x(12)-X)^2}/N]
After solving using that formula;
SD = 3.476
b) 95% confidence in interval for the population mean days absent for sickness.
Lower Bound = X - t(α/2)*s/√n
Upper Bound = X + t(α /2)*s/√n
where
α /2 = (1 - confidence level)/2 = 0.025
X = sample mean = 5.083333333
t(α/2) = critical t for the confidence interval = 2.20098516
s = sample standard deviation = 3.476108936
n = sample size = 12
df = n - 1 = 11
Thus,
Lower bound = 2.874719086
Upper bound = 7.291947581

The above function is an absolute value function
Next, we plot the graph using a graphing calculator

How to describe the transformation from the parent function?From the question, we have the following function that can be used in our computation:
f(x) = |x| --- the parent function of an absolute value function
g(x) = -|x + 3| - 4 -- the transformed function
First, we have the transformation to be:
From f(x) = |x| to f'(x) = |x + 3|
This means the function is translated left by 3 units
Next, we have:
From f'(x) = |x + 3| to f'(x) = -|x + 3|
This means the function is reflected across the x-axis
Lastly, we have:
From f'(x) = -|x + 3| to g(x) = -|x + 3| - 4
This means the function is translated down by 4 units

Find the slope of the line that contains the following points: (-7, 8) and (12, 8)
The slope of the line that contains the points: (-7, 8) and (12, 8) is 0
How to calculate the slope of the line?From the question, the points are given as
(-7, 8) and (12, 8)
Rewrite the above points properly
So, we have the following ordered pairs
(x, y) = (-7, 8) and (12, 8)
The slope of the line is then calculated using the following slope equation
Slope = (y₂ - y₁)/(x₂ - x₁)
Where
(x, y) = (-7, 8) and (12, 8)
Substitute the known values in the above equation
So, we have the following equation
Slope = (8 - 8)/(12 + 7)
Evaluate
Slope = 0
Hence, the slope of the line is 0

An arithmetic sequence has first term 13 and common difference 6. Find the 25th term
of the sequence.
Answer:
a₂₅ = 157
Step-by-step explanation:
the nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 13 and d = 6 , then
a₂₅ = 13 + (24 × 6) = 13 + 144 = 157
