Answer:
If [tex]e^{x\cdot y}-y^{2} = e-4[/tex], then at [tex]x = \frac{1}{2}[/tex] and [tex]y = 2[/tex], [tex]\frac{dy}{dx} \approx 2.059[/tex].
Step-by-step explanation:
Let [tex]e^{x\cdot y}-y^{2} = e-4[/tex]. At first we determine the first derivative of the function by implicit differentiation:
[tex]e^{x\cdot y}\cdot \left(y+x\cdot \frac{dy}{dx} \right)-2\cdot y \cdot \frac{dy}{dx} = 0[/tex]
[tex]y\cdot e^{x\cdot y}+x\cdot e^{x\cdot y}\cdot \frac{dy}{dx} -2\cdot y\cdot \frac{dy}{dx} = 0[/tex]
[tex]y\cdot e^{x\cdot y}= (2\cdot y -x\cdot e^{x\cdot y})\cdot \frac{dy}{dx}[/tex]
[tex]\frac{dy}{dx} = \frac{y\cdot e^{x\cdot y}}{2\cdot y - x\cdot e^{x\cdot y}}[/tex]
If we know that [tex]x = \frac{1}{2}[/tex] and [tex]y = 2[/tex], then the computed value of the function is:
[tex]\frac{dy}{dx} = \frac{(2)\cdot e^{\left(\frac{1}{2} \right)\cdot (2)}}{2\cdot (2)-\left(\frac{1}{2} \right)\cdot e^{\left(\frac{1}{2} \right)\cdot (2)}}[/tex]
[tex]\frac{dy}{dx} \approx 2.059[/tex]
If [tex]e^{x\cdot y}-y^{2} = e-4[/tex], then at [tex]x = \frac{1}{2}[/tex] and [tex]y = 2[/tex], [tex]\frac{dy}{dx} \approx 2.059[/tex].

Answer:
A. The amount of water in the fountain decreases 3 cm each day from a starting depth of 24 cm
Step-by-step explanation:
It starts at 24 cm, we know that, so we can cross out B and D
We know the amount of water is decreasing so we can cross out C.
That leaves A as your answer :)

Slope = 1, y-intercept = -2
please show work
Answer:
The slope intercept form would be y=x-2
Step-by-step explanation:
The slope intercept form is y=mx+b. In this case, y and x are undefined, so you keep them as variables.
The variable m stands for the slope, and you multiply it with x. Since it is 1, and one times anything keeps the number the same, you can keep the 1 out. now we have y=x+b.
The y-intercept us -2, so we replace that with b. y=x+(-2). Since adding a negative is the same as subtracting, we can change the operation.
So, you end up with y=x-2.

The balance scale shows the equation 2x + 3 = 2y + 5.
Which equation can be used to calculate x?
x = y + 2
x=y-2
x = y + 1
x = y -1
i need the question and help understand. i got the y=2x+ part but other than that i don’t know what to but after the +!! i need help
Answer:
y = 2x - 2
Step-by-step explanation:
Slope-intercept form is y = mx + b
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

A speed skater completers a 500-meter race in 40 seconds. A cheetah runs 260 meters in 10 seconds. How do their speeds compair? Find the number of meters a speed skater and a cheetah travel in one second.
A speed skater travels ___ meters per second.
A cheetah travels ___ meters per second.
Answer:
A speed skater travels 12.5 meters per second
A cheetah travels 26 meters per second
Step-by-step explanation:
To find their speeds, divide the number of meters by the number of seconds:
Speed skater:
500/40
= 12.5 meters per second
Cheetah:
260/10
= 26 meters per second
So, a speed skater travels 12.5 meters per second and a cheetah travels 26 meters per second.

6 There are 10 lanes in the bowling alley where Harold bowls. He wants to make a
scale drawing of the bowling alley using a scale of 3 cm to 15 ft. One lane,
including gutters, is 60 ft long and 5 ft wide. What will the width of all 10 lanes on
his drawing be?
Answer:
The width of 10 lanes would be a total of 10 centimeters , 1 cm for each lane on his drawing.
Step-by-step explanation:
The scale he uses is
15 ft= 3 cm
1 feet = 3/15 cm
1 cm= 15ft/3= 5 ft
One lane = 60 ft long and 5 ft wide
In centimeters it would be 60 ft / 5ft = 12 cm long and 5 ft/5ft= 1 cm wide
The width of 1 lane is 1 cm .
The width of 10 lanes would be a total of 10 centimeters , 1 cm for each lane on his drawing.

Answer:
16π = 50.27
Step-by-step explanation:
First lets find the area of both triangles
A = πr²
Smaller Area:
A = πr²
A = π 3²
A = π9
A = 9π
Larger Area:
A = πr²
A = π(5)²
A = π25
A = 25π
Now subtract the smaller from the larger to get the shaded left over
25π - 9π = 16π
