According to Ohm's Law, in an electrical circuit the voltage V (in volts) is related to the current I (in amps) and the resistance R (in ohms) by V = TR. Sup pose that when the current is 5 amps and the resistance is 6 ohms, the current is increasing by 0.3 amps/minute. What will be the rate of change of the resistance at that moment if the voltage remains unchanged? Make sure your answer has units! .
Answer:
The resistance is decreasing at a rate of 0.36 ohms/minute.
Step-by-step explanation:
The mathematical form of the Ohm's law is given by :
V = IR ...(1)
Where V is voltage, I is current and R is resistance
Given,
I = 5 A
R = 6 ohms
dI/dt = 0.3 A/min
Differentiate equation (1) wrt t:
[tex]\dfrac{dV}{dt}=I\dfrac{dR}{dt}+R\dfrac{dI}{dt}[/tex]
When V is constant, dV/dt = 0
[tex]0=5\times \dfrac{dR}{dt}+6\times 0.3\ A/s\\\\1.8=-5\times \dfrac{dR}{dt}\\\\\dfrac{dR}{dt}=-0.36\ \Omega/min[/tex]
So, the resistance is decreasing at a rate of 0.36 ohms/minute.

Kevin is observing the population of the fish he put into a pond. He built a pond and populated it with 500 fish. The population of the fish doubles every year.
Use x to represent the number of years and y to represent the population of the fish.
Enter an equation that represents this scenario in the box.
PS: The answer is either y=500(2)^x or f(x)=500(2^x)
I'm not sure which one is correct.
Answer:
go with the one you Think is the right answer That is what my mom says most of the time I'm right

2. 2/1 is the ratio of seltzer to juice. It means that there is twice as much seltzer as there is juice.
3. (2,4) represents the amount of seltzer and juice. At this point there are 4 cups of seltzer, and two cups of juice.
4. (1,2) can be used to find the constant of proportionality and slope.
5. y=2x
6. y=2*15
y=30

Which line is a line of symmetry for the triangle?
A. A
B. D
C. B
D. C
Which represents an exterior angle of triangle EGF?
O ZMEG
O ZNEG
O ZPEQ
O ZRFS
Answer:
The correct answer is:
ZNEG/∠NEG
Step-by-step explanation:
An exterior angle is one outside the triangle that is formed by extending two of the sides of the triangle. Angle NEG is formed by extending EG and EF; this makes it an exterior angle.
56 = 17n - 29
what is the value of n
Answer:
n=5
Step-by-step explanation:
take 29 add to 56 then divided by 17
Answer:
5
Step-by-step explanation:
56 = 17n - 29
-17n = -29 - 56 [remember: when u transfer a positive number it becomes negative and when u transfer a negative number it becomes positive]
-17n = -85
n = -85/-17
n = 5
hope u understood^^

Function g can be thought of as a scaled version of f(x)=x^2
Answer:
g(x)=2x^2
Step-by-step explanation:
If you look at (1,1) for the blue function then (2,2) for g(x), you can kind of see that it is scaled by 2 (meaning its just twice as big). In another case you can see the blue function passing through (2,4), which matches with the point given to you for g(x), (4,8), which is twice as big.
The function of g(x) = 2x² can be thought of as a scaled version of f(x) = x².
What is Parabola?A parabola is a U-shaped curve this is drawn for a quadratic function,
f(x) = ax² + b x + c. The graph of the parabola is downward (or opens down), when the price of a is much less than 0, a < 0. The graph of the parabola is upward (or opens up) when the value of a is more than 0, a > 0.
parabola, open curve, a conic segment produced via the intersection of a proper circular cone and a plane parallel to an element of the cone.
To determine the function of g(x) can be thought of as a scaled version of f(x) = x²
When considering (1,1) for the blue function and (2,2) for g (x),
Its two-scale scaling can be seen in some parts implying that it is simply twice as large.
The blue function is visible in another instance as it passes through (2,4),
which corresponds to the point that was provided for g(x) (4,8),
which is twice as big.
Given that f(x) = x²
then g(x) = 2f(x)
Thus, the function of g(x) = 2x²

Question 1 (10 points)
(03.01 MC)
A video game is on sale at Amazon for 30% off the original price of $28.50. Both Pat and Henri want to purchase the game, but they only have $22 each. They each have to pay 10% sales tax. Pat and Henri have different strategies to calculate the price and decide if they have enough money to get the game.
Pat takes 30% of $28.50 and subtracts that from the original price. She takes 10% of the sale price and adds it to the sale price to find the total amount she would have to pay.
Henri finds 70% of the original price and then calculates 110% of the sale price.
Will Pat's strategy calculate the correct total? Explain the calculations.
Will Henri's strategy calculate the correct total? Explain the calculations.
Do they each have enough to purchase the game?
