Implicit function
[tex]\frac{d y}{d x} = \frac{-1}{2y}[/tex]
Step-by-step explanation:
Explanation:-
Given y² + x - 3=0 ...(i)
Differentiating equation (i) with respective to 'x', we get
[tex]2 y \frac{d y}{d x} +1 = 0[/tex]
⇒ [tex]2 y \frac{d y}{d x} = -1[/tex]
⇒ [tex]\frac{d y}{d x} = \frac{-1}{2y}[/tex]
[tex]\frac{d y}{d x} = \frac{-1}{2 (3)}[/tex]
[tex]\frac{d y}{d x} = \frac{-1}{6}[/tex]

Circle A and Circle B are congruent circles. Which statement must be true?
a. Circle A and Circle B have the same center.
b. The radii of Circle A and Circle B have the same length.
c. Circle A and Circle B have exactly two points in common.
d. Circle A and Circle B touch at one point.
Answer:
B
Step-by-step explanation:
congruent mean the same, therefore the circles must be the same since they are congruent.
Answer:
B. The radii of Circle A and Circle B have the same length.
Step-by-step explanation:
The radii, diameter, and circumference would be the same length for two circles that are congruent, therefore, the answer is B.

Angles A and B are alternate exterior angles: they are on the outside of the parallel lines and opposite sides of the transversal. This means that they are congruent. So, we can set up an equation.
6x-2=4x+48
We subtract 4x from both sides.
2x-2=48
We add 2 to both sides.
2x=50
Divide both sides by 2.
x=25.
Have a wonderful day! :D
Answer:
x = 25
∠A = 148
Step-by-step explanation:
opposite exterior angle ∠A = ∠B
where
∠A = 6x - 2°
∠B = 4x + 48°
6x - 2° = 4x + 48°
6x - 4x = 48° + 2°
2x = 50°
x = 50°/2
x = 25
plugin x into ∠A = 6x - 2°
∠A = 6(25) - 2°
∠A = 148

Answer:
Scientist B
Step-by-step explanation:
1 kg = 2.2 lbs
1L = 2.11 pints
So let's convert Scientist B's data.
3.0lbs salt = 3.0/2.2 = 1.36kg
6 pints water = 6/2.11 = 2.84L water
Scientist A
1kg salt
3.0L water
We now figure out the concentration of salt in water.
Scientist A Scientist B
1kg/3.0L = .33kg/L 1.36kg/2.84L = .48kg/L
So scientist B had a more concentrated solution.

Answer:
C
Step-by-step explanation:
Make the equation from the blocks:
-7x + 7 = 5x + 16
Then simplify:
Subract 7 from both sides:
-7x = 5x + 9
Add 7x:
0 = 12x + 9
Subtract 9:
-9 = 12x
x = -9/12 = -3/4

What is the scale factor from Figure A to Figure B?
Answer:
3
Step-by-step explanation:
How do you find the magnitude and positive direction angle of the vector
v = 6i − 6j?
Answer:
Step-by-step explanation:
Given the vector v = 6i-6j, the magnitude is expressed as shown;
|v| = √6²+(-6)²
|v| = √36+36
|v| = √72
|v| = √2×36
|v| = √36×√2
|v| = 6√2
The modulus of the vector is 6√2
To get the direction, we will use the formula;
(theta) = tan^-1(y/x)
(theta) = tan^-1(-6/6)
(theta) = tan^-1(-1)
(theta) = -45°
Since the angle is negative and tan theta is negative the in the second quadrant, the positive direction angle of the vector will be 180° - 45° = 135°
Barnika bought 100 eggs for Rs. 900. Out
of them. 8 were broken. She sold the remaining eggs
at the rate of Rs. 10.50 each. Find the profit or loss
percent.
Step-by-step explanation:
cost of an egg= 900/100= Rs.9
Total cost = 100×9=Rs.900
when 8 eggs broken, the eggs remained to sell is 92(100-8)
Total sales = 10.50×92=Rs.966
profit = total cost-total sales
profit =966-900= Rs.66
profit percentage =profit/total sales×100%
66/966×100%=6.832%
find the inverse (f^-1(x)) of the function f(x)=5+1/2x
Answer:
f^-1(x) = 2x - 10
Step-by-step explanation:
f(x) = 5 + 1/2 x
y = 5 + 1/2 x
x = 5 + 1/2 y
1/2 y = x - 5
y = 2x - 10
f^-1(x) = 2x - 10
a number rounded to the nearest hundred thousand is 400,000. The same number rounded to the nearest ten thousand is 350,000. What could the number be?
Answer:
360000
Step-by-step explanation:
Well, we know the number must be above 350,000 because it was rounded up to 400,000. In order for the number to round down to 350,000 the number would have to be between 350,000-354999. So, the number could be any number in between those two numbers.
For example: The number COULD be 351,000 but, that is not the only possible answer.
but the answer would be 360000.
Explain the meaning of the coefficient of determination in this problem Group of answer choices 97.60% of the variation in receipt per theater can be explained by the variation in Twitter activity 98.79% of the variation in receipt per theater can be explained by the variation in Twitter activity 97.60% of the variation in Twitter activity per theater can be explained by the variation in receipts 0.9879% of the variation in receipt per theater can be explained by the variation in Twitter activity
Answer:
97.60% of the variation in receipt per theater can be explained by the variation in Twitter activity
Step-by-step explanation:
The coefficient of determination can be computed from the data
Movie Twitter Activity Receipts
The Devil Inside 219509 14763
The Dictator 6405 5796
Paranormal Activity 3 165128 15829

Act of Valor 9152 8054
Here twitter activity be the independent variable and Receipts be the response variable.
Using MS Excel for regression analysis
DATA>DATA ANALYSIS>REGRESSION
Selecting twitter activity as X variable and Receipts as Y variable. We get the following output
SUMMARY OUTPUT

Solve the inequality 2x ≥ 6
Answer:
I think the answer would be x = 3, 4, 5, 6 (Anything greater than 3)
The answer is: x ≥ 3
Step-by-step explanation:
I think this is the answer because:
1) Since the sign ≥ means equal to or less than, x has to equal 3 or greater.
2) This is because if x = 3 then, 2 x 3 equals to 6. 6 and 6 are equal. If x = 4 then, 2 x 4 would equal 8. 8 is greater than 6.
3) Since 2x has to be something equal to or greater than 6, x has to equal 3 or something greater than 3.
Hope this helps!
The solution of the inequality 2x ≥ 6 is greater than or equal to three.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The inequality is given as,
2x ≥ 6
Simplify the inequality, then the value of x will be
x ≥ 6/2
x ≥ 3
Thus, the value of the variable x is greater than or equal to three.
