The cost of the pendant is 3/4 the cost of the bracelet. If their total cost is P413 how much does the pendant cost?
Answer:
P 717
Step-by-step explanation:
Fraction addition using algebra:
Let the cost of bracelet = x
[tex]\sf Cost \ of \ pendent = \dfrac{3}{4}*Cost \ of \ bracelet[/tex]
[tex]\sf = \dfrac{3}{4}x[/tex]
Cost of bracelet + cost of pendent = 413
[tex]\sf x + \dfrac{3}{4}x = 413\\\\ \dfrac{4}{4}x+\dfrac{3}{4}x=413[/tex]
[tex]\sf \dfrac{7}{4}x=413[/tex]
Muliply both sides by 4,
[tex]\sf 4*\dfrac{7}{4}x = 413*4\\\\[/tex]
7x = 413 * 4
Now, divide both sides by 7
[tex]\sf x = \dfrac{413*4}{7}\\\\ x = 59*4\\\\x = 236[/tex]
Cost of bracelet = P 236
Cost of pendent = 413 - 236
= P 177

The first derivative by implicit differentiation of 2 · x⁶ + 5 · x⁴ · y - 7 · x · y⁶ = 8 is y' = (7 · y⁶ - 20 · x³ · y - 12 · x⁵) / (5 · x⁴ - 42 · x · y⁵).
How to find the derivative of a given function by implicit differentiation
Implicit differentiation is a differentiation method for implicit functions that combines chain rule and derivative rules. First, define the original function:
2 · x⁶ + 5 · x⁴ · y - 7 · x · y⁶ = 8
Second, use chain rule and derivative rules in the expression of the previous step:
12 · x⁵ + 20 · x³ · y + 5 · x⁴ · y' - 7 · y⁶ - 42 · x · y⁵ · y' = 0
Third, clear y' within the resulting equation:
12 · x⁵ + 20 · x³ · y - 7 · y⁶ + (5 · x⁴ - 42 · x · y⁵) · y' = 0
(5 · x⁴ - 42 · x · y⁵) · y' = 7 · y⁶ - 20 · x³ · y - 12 · x⁵
y' = (7 · y⁶ - 20 · x³ · y - 12 · x⁵) / (5 · x⁴ - 42 · x · y⁵)
The first derivative is y' = (7 · y⁶ - 20 · x³ · y - 12 · x⁵) / (5 · x⁴ - 42 · x · y⁵).

WHOEVER ANSWERS AND SHOW WORK GETS BRAINLIEST AWARD. Show that f(x)= 2x-3/2 and g(x)= 2x+3/2 are inverse functions. Must show fog=x and gof=x.
The functions f(x) = (2x - 3) / 2 and g(x) = (2x + 3) / 2 are the inverse functions because the composite of the given functions equal to x that is fog = x and gof = x.
The conditions for two functions f and g to be inverses: f(g(x)) = x or g(f(x)) = x.
where, f(g(x)) and g(f(x)) is the composite function.
We are given:
f(x) = (2x - 3) / 2
g(x) = (2x + 3) / 2
Let us find the value of f(g(x)) and g(f(x)):
Substitute the value of x with g(x) in f(x), we will get:
f(g(x)) = (2 * g(x) - 3) /2 = (2 * ((2x + 3) / 2) - 3) /2 = (2x + 3 - 3) / 2 = 2x / 2 = x
So, f(g(x)) = x.
Substitute the value of x with f(x) in g(x), we will get:
g(f(x)) = (2 * f(x) + 3) /2 = (2 * ((2x - 3) / 2) + 3) /2 = (2x - 3 + 3) / 2 = 2x / 2 = x
So, g(f(x)) = x.
Thus, the functions f(x) = (2x - 3) / 2 and g(x) = (2x + 3) / 2 are the inverse functions because the composite of the given functions equal to x that is fog = x and gof = x.

A board game uses the deck of 20 cards shown to the right. Two cards are selected at a random from this deck. Calculate the probability that first card selected has a yellow bird and second cared selected has a lion both with and without replacement
The probability with replacement is = 1/16
The probability without replacement is= 5/16
What do you mean by probability with replacement?
When the results must be put back into the sample space, the probability with replacement is utilized. This means that once an item is selected, it is replaced in the sample space, keeping the sample space's total number of elements constant.
Since cards should be replaced, 5 lions or 5 birds
so, the probability is
= 5/20 ÷ 5/20
=1/16
without replacement,
since cards should not be put back, for the second draw only 19 cards are left
so, the probability is
=5÷20 × 5÷19
=5/16
Hence ,
The probability with replacement is = 1/16

To help out with her retirement savings, Lena invests in an ordinary annuity that earns 3.6% interest, compounded quarterly. Payments will be made at the end of each quarter. How much money does she need to pay into the annuity each quarter for the annuity to have a total value of $96,000 after 18 years? Do not round intermediate computations, and round your final answer to the nearest cent
The amount of money that Lena needs to put each quarter for the annuity to have a total value of $96,000 is $953.45.
What amount should Lena deposit each quarter?An annuity is when a series of payment is made either at the beginning of a period or at the end of a period over a period of time.
An ordinary annuity is when the payment is made at the end of the period. When the interest is compounded quarterly, it means that four times in a year, the amount that is invested and the interest that has already being earned increase in value.
The formula that can be used to determine the quarterly payments is:
Payment = future value / annuity factor
Annuity factor = {[(1+r)^n] - 1} / r
Where:
r = interest rate = yearly interest / number of compounding = 3.6 / 4 = 0.9%n = total number of periods the payment is made = number of years x number of compounding = 18 x 4 = 72Payment = $96,000 / [{(1.009^72) - 1} / 0.009] = $953.45

Which ordered pair is not a solution to the inequality y ≥ 2x2 − 4x + 2?
The ordered pair that is not a solution to the inequality y ≥ 2x² - 4x + 2 is:
(-1,6).
How to obtain which ordered pair is not a solution to the inequality?The inequality is given as follows:
y ≥ 2x² - 4x + 2.
Each ordered pair has the following format:
(x-coordinate, y-coordinate).
Then the numeric value of the inequality is going to be calculated for each ordered pair, as follows:
Replacing x on the inequality by the x-coordinate of the ordered pair.Replacing y on the inequality by the y-coordinate of the ordered pair.Then the numeric values of the inequality for each ordered pair are presented as follows:
(-1,6): 6 ≥ 2(-1)² - 4(-1) + 2 -> 6 ≥ 8.(1,0): 0 ≥ 2(1)² - 4(1) + 2 -> 0 ≥ 0.(0,3): 3 ≥ 2(0)² - 4(0) + 2 -> 3 ≥ 2.(2,5): 5 ≥ 2(2)² - 4(2) + 2 -> 5 ≥ 2.The contradiction, that is, the statement which is false, is given at the following ordered pair:

How to find the system of equations?
In order to find the system of equations of the graph, we have to check the solution in the graph and then check for the system of equations that gives the same value.
Looking at the graph, the values of x and y at the point of intersection is the solution. Thus:
x = 0 and y = -2
Let's check the equations now:
5x+3y=-6, 3x+5y=-10
Solve for x and y using elimination
3 (5x+3y=-6)
5 (3x+5y=-10)
15x + 9y = -18
15x + 25y = -50
-6y = 32
y = -32/6 = -16/3 (This cannot be the system)
3x-5y=10, x-5y=-10
3x-5y = 10
x-5y = -10
2x = 20
x = 20/2 = 10 (This cannot be the system)
5x-y=2,x-5y=10
1(5x-y=2)
5(x-5y=10)
5x -y =2
5x-25y = 50
24y = -48
y = -48/24 = -2
put y = -2 into 5x -y =2:
5x -(-2) =2
5x + 2 = 2
5x = 0

Describe and correct the error in finding m<1.

What is Triangle?
A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.
Since, we know that Angle sum property of triangle is
∠A + ∠B + ∠C = 180°
Now, let ∠A = 115, ∠B = 39 and ∠C = m∠1
Substituting the value, we get
115° + 39° + m∠1 = 180°
154° + m∠1 = 180°
m∠1 = 180 - 154
m∠1 = 26°
Thus, m∠1 = 26°
Hence, The error for finding m∠1 is that angle sum of the triangle is equal to 180° and not 360°
