The Implicit Differentiation of 5x^2-xy-4y^2=0 is Dy/Dx= (5x-y)/(-4y)
Using implicit differentiation, Dy/Dx can be found by taking the derivative of both sides with respect to x.
On the left side, the derivative with respect to x of 5x2 is 10x and the derivative with respect to x of -xy is -y.
On the right side, the derivative of 4y2 with respect to x is 0.
Therefore, the equation becomes 10x - y = 0.
Solving for y gives y = 10x.
Substituting this into the original equation, we get 5x2 - 10x2 - 4(10x)2 = 0, which simplifies to -5x2 - 40x2 = 0.
Finally, we can solve for Dy/Dx:
Dy/Dx= (5x-10x)/(-4(10x))
Dy/Dx= (5x-y)/(-4y)

Malik uses an app on his phone to track how far he rides his bike. Yesterday, he biked a new trail in a total of 57.5 minutes, including a 2.5-minute water break. The app notified Malik that he rode 10 miles. What was Malik's average pace while biking?
The average pace of Malik is 0.182 mile per minute.
What is Speed?Speed is the unit rate in terms of distance travelled by an object and the time taken to travel the distance.
Speed is a scalar quantity as it only has magnitude and no direction.
Given that,
Distance Malik rode on a trail = 10 miles
Malik biked a new trail in a total of 57.5 minutes.
But he took 2.5 minutes as water break.
Total time Malik took to cover the distance = 57.5 minutes - 2.5 minutes
= 55 minutes
We have to calculate the average pace of Malik which is actually the speed.
Speed = Distance / Time
= 10 miles / 55 minutes
= 0.182 mile per minute
Hence Malik rides in an average pace of 0.182 mile per minute.

when f(x) = 6x² - 2x - 5, evaluate f(-2)
Answer:
23
Step-by-step explanation:
Given Information:
f(x) = 6x² - 2x - 5If we have to evaluate f(-2), we can consider that f(x) = f(-2) = 6x²- 2x - 5.
So, if f(x) = f(-2), then we have the following solution: x = -2.Now, we can substitute the solution into the quadratic equation and simplify it to its simplest possible form using the solution (x = -2).
⇒ f(-2) = 6x² - 2x - 5 ⇒ f(-2) = 6(-2)² - 2(-2) - 5 ⇒ f(-2) = 6(-2)(-2) - 2(-2) - 5 ⇒ f(-2) = 6(4) + 2(2) - 5 ⇒ f(-2) = 24 + 4 - 5 ⇒ f(-2) = 24 - 1 = 23Therefore, the evaluated form for f(-2) is 23.

What is value?Value is the worth of something that is measured in terms of its quality, importance, and usefulness. It is a fundamental concept in economics, finance, and business, as it reflects the perceived benefits of a good or service compared to its cost. Value can be subjective, as it is often based on personal opinion or preference. It can also be quantified and measured in terms of money, time, or resources.
Compound interest is the concept of earning interest on the initial principal and any interest previously earned. When the interest is compounded continuously, the interest is added to the principal more frequently than when it is compounded semiannually, resulting in a larger final balance.
The electrician's initial investment of $9,000 compounded semiannually at 2.45% for 30 years would have a balance of $18,685.71.
However, if the same investment had been compounded continuously at 2.45%, the balance after 30 years would be $18,769.34, which is $83.63 more than the semiannually compounded balance.

Garrett went to Good Buys where all prices are discounted 15%. He buys a vintage Waring blender, after the 15% discount, for $42. What is the original price of the blender before the discount. Round your answer to the nearest hundredths.
The original price of the blender before the discount is $49.41.
How to calculate the original price of the blenderWe shall represent the original price of the blender with the letter x so that we use $x to evaluate for the original price before the discount price as follows:
x - 15x/100 = $42 {simply the left hand expression to a single fraction}
(100x - 15x)/100 = $42 {simply the terms in the bracket}
$85x/100 = $42
$85x = $4200 {cross multiplication}
$85x/$85 = $4200/$85 {divide through by $85}
x = $49.41

IF tan(theta) = -8/7 = opposite side/adjacent side, then that means that sin(theta) = -8/(sqr(64+49) = -8/sqr113 = about -0.7526
Step-by-step explanation:
the tangents are negative in the quadrant II or IV
and sines are negative in the quadrant III or IV
so i think that this angle is in quadrant IV to satisfy for the of the both requirements.
but angle 0 seems to try and mean something other than 0 degrees or 0 radians. so It probably just means theta, which is a 0 probably with a line through it
IF tan(theta) = -8/7 = opposite side/adjacent side, then sin(theta) = -8/(sqr(64+49) = -8/sqr113 = about -0.7526

On a necklace of 150 beads 75 beads are glass and 78 are ceramic what percent of beads are glass
Answer:
Doesn't make sense but with the information given. To find the percentage of glass beads on the necklace, you need to divide the number of glass beads by the total number of beads and multiply by 100.
You can use the formula:
percent = (number of glass beads / total number of beads) x 100
In this case:
percent = (75 / 150) x 100 = 0.5 x 100 = 50
So, 50% of the beads on the necklace are glass.

How do you tell if a graph is exponential growth or decay?
To tell if a log graph is a growth or decaying, look at the slope of the line. If the slope is positive, then it is growth; if the slope is negative, then it is decay.
A positive slope indicates that the value is increasing over time, while a negative slope indicates that the value is decreasing over time. To find the slope, take two points on the line and calculate the change in the y-value divided by the change in the x-value.
If the answer is positive, the graph is growth; if the answer is negative, the graph is decay. Additionally, you can look at the y-intercept of the graph, which is the value where the line meets the y-axis. If the y-intercept is positive, the graph is growth; if the y-intercept is negative, the graph is decay.

Hello there!
∆ABC and ∆XYZ are simular so:
[tex] \displaystyle \frac{AB}{XY} = \frac{BC}{YZ} = \frac{AC}{XZ} \\ \\ \frac{2}{10} = \frac{5}{25} = \frac{AC}{20} \\ \\ \frac{1}{5} = \frac{1}{5} = \frac{AC}{20} \\ \\ \frac{AC}{20} = \frac{1}{5} \\ \\ AC = \frac{20 \times 1}{5} = 4[/tex]
Answer: 4
Answer:
4
Step-by-step explanation:
We have to find length of AC in ΔABC
Since ΔABC is similar to ΔXYZ, the corresponding sides of ΔABC to the corresponding sides of ΔXYZ should be of similar ratio
Equivalently stated
[tex]\dfrac{AB}{XY} = \dfrac{BC}{YZ} = \dfrac{AC}{XZ}[/tex]
Plugging in known values we get
[tex]\dfrac{AB}{XY} = \dfrac{2}{10} = \dfrac{1}{5}\\\\\dfrac{BC}{YZ} = \dfrac{5}{25} = \dfrac{1}{5}\\[/tex]
Thus we see that the length of each side of ΔABC is one-fifth the length of each corresponding side of ΔXYZ.
So
[tex]AC =\dfrac{1}{5} XZ = \dfrac{1}{5} \cdot 20 = 4[/tex]

Mark bought a new car. The total amount he needs to borrow is $28,716. He plans on taking out a 4-year loan at an APR of 3.12%. What is the monthly payment?
The monthly payment with given simple interest will be $673.
What is simple interest?
Simple Interest is an easy method of calculating the interest for a loan/principal amount. Simple interest is a concept that is used in many sectors such as banking, finance, automobile, and so on. When you make a payment for a loan, first it goes to the monthly interest and the remaining goes towards the principal amount.
Simple interest formula is given as:
SI=P*R*T/100
Where SI = simple interest
P = principal
R = interest rate (in percentage)
T = time duration (in years)
In order to calculate the total amount, the following formula is used:
Amount (A) = Principal (P) + Simple Interest (SI)
Now,
Amount to Borrow=$28716
Rate=3.12%
Time=4 years
SI=28716*3.12*4/100
=$3584
Total amount to pay=28716+3584
=$32300
Hence,
monthly payment for 4 years =32300/48
monthly payment=$673
