Let l be the length of a diagonal of a rectangle whose sides have lengths x and y, and assume that x and y vary with time. If x increases at a constant rate of 19 ft/s and y decreases at a constant rate of 15 ft/s, how fast is the size of the diagonal changing when x
The rate of change of the size of the diagonal is; 25.2 ft/s
By Pythagoras theorem;
The length, l of a diagonal of a rectangle whose sides have lengths x and y is;
l² = x² + y².In essence; the length of the diagonal is dependent on the length, x and y of the sides.
Therefore;
(dl/dt)² = (dx/dt)² + (dy/dt)²
where;
(dx/dt) = 19 ft/s(dy/dt) = -15 ft/sTherefore,
(dl/dt)² = 19² + (-15)²
(dl/dt)² = 361 + 225
dl/dt = √586
dl/dt = 25.2
Therefore, the size of the diagonal is changing at a rate of; 25.2 ft/s.

A cyclist travels 9.6 km in 30 minutes. What is his average speed in km/h?
Answer:
[tex]\frac{95}{5} \frac{km}{hour}= 19.2 km/hour[/tex]
Step-by-step explanation:
Average speed = distance/time
Average speed = [tex]\frac{9.6}{30} \frac{km}{min}[/tex] ; multiply by 60min/1hour
Average speed = [tex]\frac{95}{5} \frac{km}{hour}= 19.2 km/hour[/tex]
M*(x+y)+4y/(x^2-xy-y^2)=(x+2y)/(x^2-xy-Y^2),find the value of M
Answer: M = [tex]\frac{x-2y}{x+y}[/tex]
Step-by-step explanation:
[tex]\frac{M(x+y)+4y}{x^{2}-xy-y^{2} } =\frac{(x+2y)}{x^{2} -xy-y^{2} }[/tex]
M (x + y) + 4y = x + 2y (Multiply [tex]x^{2} - xy-y^{2}[/tex] in both sides)
M (x + y) = x + 2y - 4y
M (x + y) = x - 2y (Divide (x+y) from both sides)
M = [tex]\frac{x-2y}{x+y}[/tex]

what is the slope?
what is the y-intercept?
proportional or not proportional?
Answer:
Slope(m)=3
Y-intercept= 0
y = 3x +0
Proportional
Step-by-step explanation:
m = -6--12/-2--4
m=6/2
m=3
-12 = 3(-4) + b
-12 = -12 + b
0=b
Answer:
slope, m = 3
y-intercept, b = 0
Proportional
Step-by-step explanation:
If we assume this is a straight line, we can calculate the slope between two of the given points. I'll pick (-2,-6) and 2,6).
Slope is the Rise (the change in y) over the Run (the corresponding change in x).
Rise for these two points: 6 - (-6) = 12
Run for the points is: 2-(-2) = 4
Rise/Run (Slope) = 12/3 = 4
The line becomes y=3x+b
b is the y-intercept. We can either solve for b by entering one of the points, but the y-intercept is the value of y when x=0. Behold: one of the points is (0,0), so we already have b. It is 0.
y=3x+0
y=3x is the equation.
slope, m = 3
y-intercept, b = 0
A non-proportional graph is a straight line that does not go through the origin. A proportional graph is one that does, so this is a proportional graph.

The Correct choice is ~
x is all real numbers
Option D is correct, domain of the function in the graph are x is all real numbers.
What is a function?A relation is a function if it has only One y-value for each x-value.
We have to find the domain of the given function.
What can go into a function is called the Domain.
What may possibly come out of a function is called the Codomain.
What actually comes out of a function is called the Range.
IAs we observe the x values through which the curve is passing, it is passing through all the points of x axis.
So the domain will be all the real d=numbers.
Hence, Option D is correct, domain of the function in the graph are x is all real numbers.
