An equation of the tangent line to the curve [tex]x e^y+y e^x=4[/tex] at the point (0, 4) is [tex]y=-(4+e^4) x+4[/tex].
What is tangent?A tangent is described as a line that intersects a circle or an ellipse only at one point. If a line touches a curve at P, the point "P" is known as the point of tangency.
Now according to the question;
To obtain the tangent at a given point, we must first obtain the slope at that point by obtaining the differentiation value at that point [tex]\left.y^{\prime}\right|_{x=0, y=4}[/tex] as-
Consider the given equation;
[tex]x e^y+y e^x=4[/tex]
Differentiate both side with respect to x;
[tex]\begin{aligned}&\frac{d}{d x}\left(x e^y+y e^x\right)=\frac{d}{d x} 4 \\&\frac{d}{d x} x e^y+\frac{d}{d x} y e^x=0\end{aligned}[/tex]
Now apply product rule;
[tex]\begin{aligned}&e^y \frac{d}{d x} x+x \frac{d}{d x} e^y+e^x \frac{d}{d x} y+y \frac{d}{d x} e^x=0 \\&e^y \frac{d}{d x} x+x \frac{d}{d y} e^y \cdot y^{\prime}+e^x y^{\prime}+y \frac{d}{d x} e^x=0\end{aligned}[/tex]
Applying exponential and power rule;
[tex]\begin{aligned}&e^y \cdot 1+x e^y \cdot y^{\prime}+e^x y^{\prime}+y e^x=0 \\&\left(x e^y+e^x\right) y^{\prime}=-y e^x-e^y\end{aligned}[/tex]
Solve the value of y'
[tex]y^{\prime}=\frac{-y e^x-e^y}{x e^y+e^x}[/tex]
Now, find the value of slope m.
[tex]m=\left.y^{\prime}\right|_{x=0, y=4}[/tex]
[tex]\frac{-4 \cdot e^0-e^4}{0 e^4+e^0}=-4-e^4[/tex]
Now, using the point-slope formula, obtain the line equation as follows.
[tex]\begin{aligned}&\left(y-y_1\right)=m\left(x-x_1\right) \\&(y-4)=-(4+e^4) \cdot(x-0) \\&y=-(4+e^4) x+4\end{aligned}[/tex]
Therefore, an equation of the tangent line to the curve is [tex]y=-(4+e^4) x+4[/tex].

Answer:
y= 6/5 x -5
Step-by-step explanation:
You have 2 points. (0,-5) and (5,1)
If you use the formula Y2-Y1 / X2-X1,
you will have 1 - (-5) on the numerator, which equals 6
you will have 5 - 0 in the denominator, which equals 5
6/5 is your slope, and the point on the y-intercept is what you put at the end of the equation.

How are time, distance, and speed related?Speed indicates how quickly something or someone is moving. Speed is calculated as follows: speed = distance * time. Following are the relationships between time, distance, and speed: Distance is directly related to speed and time. Time and speed are also negatively related. Speed is what it means. the speed at which an object's location changes in any direction. The distance traveled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity. Distance is the sum of an object's movements, regardless of direction. The flow of events from the past into the future is known as time. Time only ever moves in one way. Time can go either forward or backward, but not both.

Given f(x)=x²-3x - 23 and
g(x)=x-1, find (fog)(x).
The required function is (fog)(x) = x^2 – 5x – 19
We have been given two functions which are:
f(x) = x^2 – 3x – 23
g(x) = x – 1
We need to find (fog)(x) which is also equal to f(g(x)).
In this, we have to replace x with the function g(x) in the function, f(x). numerically
f(g(x)) = g(x)^2 – 3g(x) – 23
Now we will write the value of g(x) in the above equation. We will get
f(g(x)) = (x-1)^2 – 3(x-1) – 23
f(g(x)) = x^2 + 1 – 2x – 3x + 3 – 23
f(g(x)) = x^2 – 5x – 19
Hence (fog)(x) = x^2 – 5x – 19 is the required function.

The simple interest for R 7,500 is R 1, 800, and she will get it at 3 years with interest of 8%.
Simple interest:
Simple interest means the method of calculating the interest amount for a particular principal amount of money at some rate of interest.
The formula used to calculate the simple interest is
SI = P × R × T
P = The principal is the amount that initially borrowed from the bank or invested.
R = Rate is the rate of interest at which the principal amount is given to someone for a certain time.
T= Time is the duration for which the principal amount is given to someone.
Given,
Cynthia receives a gift of r 7, 500 she decides to invest it for 3 years, she is offered two saving at 8% interest.
Here we need to find the simple interest.
We know that,
P = 7, 500

The required probability that a patient had surgery and experienced a major improvement 31% and that a patient received nonsurgical treatment 14.5%.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Number of patients who got surgery = 398,
63% of percent said they had a major improvement in their condition,
= 0.63 * 398 ≈ 250
29% among those who received nonsurgical treatment,
= 0.29 * (803 - 398)
= 0.29 * 405
≈ 117
Now,
The probability that a patient had surgery and experienced a major improvement in his or her condition.
= 250 / 803
= 31%
The probability that a patient received nonsurgical treatment and experienced an improvement in his or her condition.
= 117 / 803
= 14.5%

From the information given, we have that;
Scale drawing was used0. 25 inches represents 2 feetThe length of the building is 250 feetThen,
If 0. 25 inches = 2 feet
Then x inches = 250 feet

x × 2 = 0. 25 × 2500
Multiply through, we have;
2x = 62. 5
Make 'x' the subject by dividing both sides by 2
