if e^xy−y^2=e−4, then at x = 1/2 and y = 2, dy/dx =
Answer:
dy/dx = -0.5285
Step-by-step explanation:
e^(xy) − y² = e^(−4)
To get dy/dx, we will differentiate with respect to x applying both chain rule and product rule.
Thus;
e^(xy)[d(xy)/dx] - (d/dx)y² = 0
e^(xy)[x(dy/dx) + y] - ((dy/dx) × (d(y²)/dy)) = 0
xe^(xy)[dy/dx] + ye^(xy) - 2y = 0
Thus, rearranging we have;
dy/dx = [2y -(ye^(xy))]/xe^(xy)
We are given;
x = 1/2 and y = 2
Thus;
dy/dx = [2(2) - (2e^(½ × 2))]/(1e^(½ × 2))
dy/dx = (4 - 5.4366)/2.7183
dy/dx = -0.5285

A pair of dice was rolled many times
and the results appear below. Based
upon these results, what is the
experimental probability of rolling a
prime number?
Answer:
Step-by-step explanation:
Total outcome is
3 + 6 + 8 + 11 + 14 + 16 + 15 + 12 + 9 + 5 + 1 = 100
Favorable outcome is
3 + 6 + 11 + 16 + 5 = 41
The percent probability is
41 / 100 = 41 %
What is the y-intercept from the following ordered pairs? (-2,0)(0,4)(2,8)(4,12)
Answer: y intercept = 4
The y intercept always occurs when x = 0. This is the location where the graph crosses the y axis. From the list of points, we see that (0,4) is the location of the y intercept. We can say the y intercept is 4.

1. You purchase a car using a $15,000 loan with a 5% simple interest rate.
(a) Suppose you pay the loan off after 4 years. How much interest do you pay on your loan? Show your work. (10 points)
(b) Suppose you pay the loan off after 2 years. How much interest do you save by paying the loan off sooner? Show your work. ( 5 points)
Answer:
a) $3000
b) $1500
Step-by-step explanation:
a)
interest = Principal x rate as decimal x time
interest = 15,000 x 0.05 x 4
interest = 3000
b)
interest = Principal x rate as decimal x time
interest = 15,000 x 0.05 x 2
interest = 1500
you save $1500 if you pay after 2 years

Find the slope of a line parallel to each given line
What is the equation of the line in slope-intercept form?
Answer:
y = 4/3 + 4
Step-by-step explanation:
4/3 comes from using rise over run. 4 comes from the y-intercept.
Answer:
y = [tex]\frac{4}{3}[/tex] x + 4
Step-by-step explanation:
y = mx + b
m = [tex]\frac{rise}{run}[/tex] ; "b" is y-intercept
~~~~~~~~~~~
m = [tex]\frac{4}{3}[/tex] and b = 4
y = [tex]\frac{4}{3}[/tex] x + 4

Answer:
2 more liters of juice
Step-by-step explanation:
John bought a total of 12 liters of coke and a total of 14 liters of juice.

Answer:
2 Liters
Step-by-step explanation:
1. Multiply 1.5 times 8.
1.5 x 8 = 12 L
2. Multiply 7 times 2.
7 x 2 = 14 L
3. Subtract the amount of coke from the amount of juice.

Four tenths of a number increased by the second number equals 19. One tenth of the first number decreased by the second number is equal to 1. What are the two numbers?
Answer:
The two numbers are 40 and 3
Step-by-step explanation:
Assume that the first number is x and the second number is y
∵ Four tenths = [tex]\frac{4}{10}[/tex] = 0.4
∵ One tenth = [tex]\frac{1}{10}[/tex] = 0.1
∵ Four tenths of 1st number increased by the 2nd number equals 19
∵ The 1st number = x and the 2nd number = y
∴ 0.4x + y = 19 ⇒ (1)
∵ One tenth of the 1st number decreased by the 2nd number is equal to 1
∴ 0.1x - y = 1 ⇒ (2)
Now we have a system of equations to solve it
→ Add equations (1) and (2) to eliminate y
∵ (0.4x + 0.1x) + (y + -y) = (19 + 1)
∴ 0.5x + 0 = 20
∴ 0.5x = 20
→ Divide both sides by 0.5 to find x
∵ [tex]\frac{0.5x}{0.5}[/tex] = [tex]\frac{20}{0.5}[/tex]
∴ x = 40
→ Substitute the value of x in equation (1) or (2) to find y
∵ 0.4(40) + y = 19
∴ 16 + y = 19
→ Subtract 16 from both sides
∴ 16 - 16 + y = 19 - 16
∴ y = 3
∴ The two numbers are 40 and 3

What is the general equation of a Straight line?
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have the following equation as -
6x + 12 = 5x + 35
Assume that -
6x + 12 = 5x + 35 = y
y = 6x + 12
y = 5x + 35
Graph the equations. The points of intersection would be the solutions.
Therefore, the equation 6x + 12 = 5x + 35 will have one possible solution i.e. (23, 150)

What are Exponents?Exponents are the method of writing numbers, especially large numbers, in terms of a base and an exponent, which is written as the power of base.
Given that,
5⁵ . 5ˣ = 5²
We have to use a multiplication rule for exponent here.
xᵃ . xᵇ = xᵃ⁺ᵇ
Using this,
5⁵⁺ˣ = 5²
⇒ 5 + x = 2
⇒ x = -3
p⁻³ . p⁻⁶ = p^y
Using the same rule of exponent,
p⁻³⁺⁻⁶ = p^y
⇒ y = -3 - 6 = -9
9² . 9⁻⁷ . 9ⁿ = 9⁻⁵
9²⁻⁷⁺ⁿ = 9⁻⁵
⇒ 2 - 7 + n = -5
⇒ n = 0
Hence the values of x, y and n are -3, -9 and 0 respectively.
