Answer:

Grover has $24, Percy has $31 and Annabeth has $19.

Step-by-step explanation:

Create equations to represent the situation.

let a be Annabeth

let g be Grover

let p be Percy

a + g = 43      Together, Annabeth and Grover have $43

g + p = 55    If Grover and Percy combine their money, they have $55

p = g + 7        Percy has $7 more than Grover

See if any of the equations can be combined. For example, we know p is g+7.

Substitute p for g+7 in an equation that has the variable p.

g + p = 55

g + g + 7 = 55    Combine like terms (g)

2g + 7 = 55   Start isolating g. Subtract 7 from both sides

2g = 55 - 7

2g = 48     Divide both sides by 2

g = 48/2    

g = 24         Money Grover has

Use the equation p = g + 7. Find "p" by substituting g for 24.

p = g + 7

p = 24 + 7   Add

p = 31    Money Percy has

Substitute g for 24 in the last equation, a + g = 43, to find a.

a + g = 43

a + 24 = 43    Subtract 24 from both sides

a = 43 - 24

a = 19     Money Annabeth has

Therefore Grover has $24, Percy has $31 and Annabeth has $19.

Answer:

Grover has $24, Percy has $31 and Annabeth has $19.

g + g + 7 = 55    Combine like terms (g)

2g + 7 = 55   Start isolating g. Subtract 7 from both sides

2g = 55 - 7

2g = 48     Divide both sides by 2

g = 48/2    

g = 24         Money Grover has

Use the equation p = g + 7. Find "p" by substituting g for 24.

p = g + 7

p = 24 + 7   Add

p = 31    Money Percy has

Substitute g for 24 in the last equation, a + g = 43, to find a.

a + g = 43

a + 24 = 43    Subtract 24 from both sides

a = 43 - 24

a = 19     Money Annabeth has

Therefore Grover has $24, Percy has $31 and Annabeth has $19.

To solve the simultaneous equations, set the two equations equal to each other, simplify, solve for x, and substitute the values of x back into one of the original equations to solve for y. The solutions are (2, 9) and (-2, -7).

To solve the simultaneous equations:

y = 5x^2 + 4x - 19

y = 4x + 1

Let's set the two equations equal to each other:

5x^2 + 4x - 19 = 4x + 1

Now, simplify and solve for x:

5x^2 + 4x - 4x - 19 - 1 = 0

5x^2 - 20 = 0

Divide both sides by 5:

x^2 - 4 = 0

Factor the equation:

(x - 2)(x + 2) = 0

Set each equation equal to zero:

x - 2 = 0 or x + 2 = 0

Solve for x:

x = 2 or x = -2

Now, substitute the values of x back into one of the original equations to solve for y:

When x = 2:

y = 5(2)^2 + 4(2) - 19

y = 20 + 8 - 19

y = 9

When x = -2:

y = 5(-2)^2 + 4(-2) - 19

y = 20 - 8 - 19

y = -7

Therefore, the solutions to the simultaneous equations are (2, 9) and (-2, -7).

Step-by step

What do we already know about the equation?

We know that they EACH bought a hockey puck($17) and 2 shirts

Answer:

Roberta earns $164.4 on an 8 hr shift.

Step-by-step explanation:

In one hour  Roberta makes $9

So if she works for 8 hours she will be making

=> ( 9 X 8)$

=>72$

Also she earns a commission of 10.5% on selling a jewellery  worth $880

So 10.5% of 880 is

=> [tex]\frac{10.5}{100}\times 880[/tex]

=>  [tex] 0.105\times 880[/tex]

=> 92.4

Hence  Roberta will be earning a total amount of

Answer:

The % of the increase in population from 1980 to 2000 will be 72.8%

Step-by-step explanation:

Let the population in the year of 1980 was x.

If the population from 1980 to 1990 has increased by 20%, then the population in the year 1990 will be [tex]x(1 + \frac{20}{100}) = 1.2x[/tex].

Now, from 1990 to 2000, the population has again increased by 20%.

So, the population in the year 2000 will be [tex]1.2x(1 + \frac{20}{100}) = 1.44x[/tex].

Again, from 2000 to 2010, the population has increased by 20%.

Therefore, the population in the year 2010 will be [tex]1.44x(1 + \frac{20}{100}) = 1.728x[/tex].

Now, the population increased from x to 1.728x between the years 1980 to 2010.

Hence, the % of the increase in population from 1980 to 2000 will be [tex](\frac{1.728x - x}{x}) \times 100\% = 72.8\%[/tex] (Answer)

The question is a college-level mathematics problem involving taking the third derivative of the function f(x) = 2x/(x^2 - 1). The process requires the application of quotient rule and chain rule of differentiation.

The student question involves calculating the third derivative of the function f(x) = 2x/(x2 - 1). This function is a rational function and can be differentiated using the quotient rule and chain rule of differentiation. Let's proceed with the derivative calculations.

First, we should recall that the function can be rewritten as:

f(x) = 2x/(x2 - 1) = 2x/[(x - 1)(x + 1)]

Now we can calculate the derivatives. For the first derivative f'(x), we use the quotient rule:

f'(x) = [(x2 - 1)(2) - (2x)(2x)]/(x2 - 1)2

For the second derivative f''(x), we differentiate f'(x) again:

f''(x) = Derivative of f'(x) with respect to x

The third derivative f'''(x) is then the derivative of f''(x). Calculations for the second and third derivatives can be a bit complex and lengthy, and it is necessary to apply the quotient rule and product rule carefully.

Through this process, we will arrive at the third derivative, f'''(x), which is what the question asks for.

Answer:

The perimeter of crater lake is 17.27 miles.

Step-by-step explanation:

Given as :

The shape of the lake is like a circle

The diameter of lake = d = 5.5 miles

∵ shape pf lake is circle, so the diameter of circle = d = 5.5 miles

Let The perimeter of crater lake = p miles

Now, As we know

The perimeter of circle = [tex]\pi[/tex] × diameter

the value of  [tex]\pi[/tex] = 3.14

Or, p =  [tex]\pi[/tex] × d

Or, p =  [tex]\pi[/tex] × 5.5 miles

Or, p =  3.14 × 5.5 miles

∴ p = 17.27 miles

So, The perimeter of circle = perimeter of lake = p = 17.27 miles

Hence, The perimeter of crater lake is 17.27 miles. Answer

Answer:

The graph with B(2,-3) i.e) y=[tex]\frac{-3}{2}[/tex] x goes through the point M(-10,15).

Step-by-step explanation:

Consider M(-10,15) and given that equation is y = kx.

Now, substitute M(-10,15) in the equation

⇒ 15 = k × -10

⇒ k = [tex]\frac{15}{-10}[/tex] = [tex]\frac{-3}{2}[/tex]

⇒ y = [tex]\frac{-3}{2}[/tex] x

Now, check with the given points B(2,-3) and B([tex]3\frac{1}{3}[/tex] , -2)

1) B(2,-3)

y = [tex]\frac{-3}{2}[/tex] x

⇒(-3) = [tex]\frac{-3}{2}[/tex] × 2

⇒ -3 = -3 ⇒ LHS = RHS

⇒ B(2,-3) is the required point.

2) for b([tex]3\frac{1}{3}[/tex] , -2)

LHS ≠ RHS.

So,The graph with B(2,-3) i.e) y=[tex]\frac{-3}{2}[/tex] x goes through the point M(-10,15).

Answer:

Step-by-step explanation:

(2,-4)....x1= 2 and y1 = -4

(p,8).....x2 = p and y2 = 8

slope(m) = 1/2

now use the slope formula (y2 - y1) / (x2 - x1) and sub in what we know...

slope(m) = (y2 - y1) / (x2- x1)

1 / 2 = (8 - (-4) / (p - 2)

1 / 2 = (8 + 4) / (p - 2)

1/2 = 12 / (p - 2) .....now multiply both sides by (p - 2)

1/2(p - 2) = 12

1/2p - 1 = 12

1/2p = 12 + 1

1/2p = 13

p = 13 / (1/2)

p = 13 * 2/1

p = 26

so the value of p is 26

Answer:

Therefore, Point M( 1 , -2 ) is the Mid point of segment ST.  

Step-by-step explanation:

Given:

Let,

point S( x₁ , y₁) ≡ ( -1 , 1)  

point T( x₂ , y₂) ≡ (3 , -5)

Point M( x , y ) is the Mid point of segment ST.  

To Find:

Point M( x , y )= ?

Solution:

As Point M( x , y ) is the Mid point of segment ST.

So we have Mid Point Formula as

[tex]Mid\ pointM(x,y)=(\frac{x_{1}+x_{2} }{2}, \frac{y_{1}+y_{2} }{2})[/tex]

On substituting the given values in above equation we get

[tex]M(x,y)=(\frac {-1+3}{2},\frac{-5+1}{2})\\\\M(x,y)=(\frac{2}{2},\frac{-4}{2}) \\\\M(x,y)=(1,-2)\ \textrm{which the required midpoint}[/tex]

Therefore, Point M( 1 , -2 ) is the Mid point of segment ST.  

Answer:

Quartile 1 (Q1) = 24

Quartile 2 (Q2) = 47

IQR = 23

Step-by-step explanation:

Given:

The set of data are:

13, 23, 24, 25, 26, 26, 37, 47, 47, 48, 50

The data are in increasing order. The number terms are, [tex]n = 11[/tex].

Therefore, the middle term = [tex]\frac{n+1}{2}=\frac{11+1}{2}=6^{th}\ term[/tex]

So, the median = 26

Now, the median divides the set of data into two parts. The median of first part is the quartile 1 and the median of second part is quartile 2.

So, the first part has the following terms:

13, 23, 24, 25, 26

Here also, [tex]n=5[/tex]. So, the third term is the median.

∴ Q1 = 24

The second part has the following terms:

37, 47, 47, 48, 50

Here also, [tex]n=5[/tex]. So, the third term is the median.

∴ Q2 = 47.

Now, IQR = Q2 - Q1 = 47 - 24 = 23.

Answer:

3x-2y^2-2

Step-by-step explanation:

3x-(2y^2+2)=3x-2y^2-2

Answer:

(1, 1 )

Step-by-step explanation:

Given the 2 equations

3x +2y = 5 → (1)

x - 2y = - 1 → (2)

Adding the 2 equations term by term will eliminate the term in y, that is

(3x + x) + (2y - 2y) = (5 - 1)

4x = 4 ( divide both sides by 4 )

x = 1

Substitute x = 1 in either of the 2 equations and solve for y

Substituting in (1)

3(1) + 2y = 5

3 + 2y = 5 ( subtract 3 from both sides )

2y = 2 ( divide both sides by 2 )

y = 1

Solution is (1, 1 )
