Answer:

the number = 8/5 or 1 3/5 or 1.6

Step-by-step explanation:

n = the number

5/2n - 11 = 4

5/2n - 11 + 11 = 5 / 2n

5/2n = 4

5/2n / 5/2 = n

Answer:

  E.  36.8 ft

  F.  59 ft

  G.  3.5 ft or 114.5 ft

Step-by-step explanation:

E. Put x=60 in the equation and do the arithmetic.

  h = -0.01·60^2 +1.18·60 +2 = -36 +70.8 +2 = 36.8

The height is 36.8 feet when the ball is 60 feet downfield.

__

F. The vertex of expression ax^2 +bx +c is x = -b/(2a). Here, that is ...

  x = -(1.18)/(2(-0.01)) = 59

The ball has traveled 59 feet downfield when it reaches its maximum height.

__

G. To find the downfield distance for a height of 6 feet, we set h=6 and solve for x.

  6 = -0.01x^2 +1.18x +2

  0.01x^2 -1.18x +4 = 0 . . . put in standard form

  x^2 -118x +400 = 0 . . . . . multiply by 100 to get rid of decimals

  x = (118 ± √(118² -4(1)(400)))/(2) = 59 ±√3081

  x ≈ 59 ± 55.5 ft = {3.5 ft, 114.5 ft}

The ball will be 6 ft high at distances of 3.5 and 114.5 ft downfield.

Answer:

1) 62.5%

2) 8-x/8=y/100 (where y is the percent)

Step-by-step explanation:

1) so there’s 8 questions in total cause each question si 5 points and 40 points is the max so 40/5=8

write a proportion where 8-3/8=y/100 (it’s 8-3 because it’s total question minus the wrong questions and you’ll get the remaining points and put it over a hundred since the max score you can get is a hundred.

so 5/8= y/100

cross multiply

500=8y

Divide 8 on both sides

you’ll get 62.5

2) Jist use the equation 8-x/8=y/100

( where x is the wrong amount of questions and y is the total percent)

Answer:

  1.63 cm (across the centerline from release)

Step-by-step explanation:

If we assume time starts counting when we release the weight from its fully-extended downward position, then the position at 1.15 seconds can be found from ...

  h(t) = -7cos(2πt/4)

  h(1.15) = -7cos(π·1.15/2) = -7(-0.233445) ≈ 1.63412 . . . cm

That is, 1.15 seconds after the weight is released from below the resting position, it will be 1.63 cm above the resting position.

__

If it is released from above the resting position, it will be 1.63 cm below the resting position at t=1.15 seconds.

Answer:

Bill is 25 years old and Jenny is 29 years old

Step-by-step explanation:

Systems of Equations:

J = 4 + B

J + B = 54

Substitute J into the first equation.

4 + B + B = 54

Add like terms.

4 + 2B = 54

Isolate the variable.

4 + 2B = 54

-4            -4

2B = 50

2B/2 = 50/2

B = 25 years old

Plug in B into the second equation of the system.

J + B = 54

J + 25 = 54

Isolate the variable.

J + 25 = 54

   -25   -25  

J = 29 years old

Check your answer. Pick whatever equation in the system and plug in your answers.

J = 4 + B

29 = 4 + 25

29 = 29

Answer:

1638

Step-by-step explanation:

40 + 2 = 42

42 + 39 = 1638

Answer:

Step-by-step explanation:

The volume of a cone is expressed as shown;

V = πr²h/3

The rate of change of volume is expressed as;

dV/dt =  ∂V/dr * dr/dt +  ∂V/dh * dh/dt

dV/dr is the rate of change of volume with respect to radius

∂V/dh is the rate of change of volume with respect to height

dr/dt is the rate of change in radius = 1.7 in/s

dh/dt is the rate of change in height = 2.2 in/s

∂V/∂r = 2πrh/3

if r = 185 and h = 134

∂V/∂r = 2π(185)(134)/3

∂V/∂r = 51, 893.73 in²

Also  ∂V/∂h =  πr²/3

if h = 134 in

 ∂V/∂h  =  π(134)²/3

∂V/∂h  =  π(134)²/3

∂V/∂h = 18,793.95in²

Substitute the given values into the differential equation above

dV/dt =  ∂V/dr * dr/dt +  ∂V/dh * dh/dt

dV/dt =  51, 893.73 *(1.7) + 18,793.95 *(2.2)

dV/dt =  88,219.341 + 41,346.68

dV/dt = 129,566.021 in³/s

Hence the volume of the cone is changing at 129,566.021 in³/s

Answer:

My answer is 33

132/4 = 33

Think of it as a fraction and simplify the fraction into a whole number

The value of 132 divided by 4 is 33.

To solve 132 divided by 4, follow these steps:

Step 1: Divide the whole number part.

Divide 132 by 4, which equals 33.

Step 2: Check for any remaining fraction or decimal part.

Since there is no remainder when dividing 132 by 4, the result is a whole number.

The final result of 132 divided by 4 is 33. When you divide 132 by 4, you are essentially grouping 132 items into 4 equal parts. Each part contains 33 items, and there are no items left over. Therefore, the division is complete, and the answer is 33. This can also be confirmed by performing the calculation:

132 ÷ 4 = 33

So, 132 divided by 4 is 33.

Answer:

x=-28

Step-by-step explanation:

Step 1: Cross-multiply.

x+4

=

8

2

(x+4)*(2)=(8)*(−6)

2x+8=−48

Step 2: Subtract 8 from both sides.

2x+8−8=−48−8

2x=−56

Step 3: Divide both sides by 2.

2x

2

=

−56

x=−28

=====================================

Work Shown:

(x+4)/(-6) = 8/3

3(x+4) = -6*8 ... cross multiply

3x+12 = -48

3x = -48-12 ... subtract 12 from both sides

3x = -60

x = -60/3 ... divide both sides by 3

x = -20

---------------------

Check:

(x+4)/(-6) = 8/3

(-20+4)/(-6) = 8/3 .... replace every x with -20

(-16)/(-6) = 8/3

(-2*8)/(-2*3) = 8/3

8/3 = 8/3 ... the '2's cancel when dividing

We get the same number on both sides, so this confirms the solution.

Answer:

36 units

Step-by-step explanation:

Perimeter of the triangle is the total distances between the vertices which can be calculated as follows using distance formula where necessary:

Distance between (-1, -4) and (9, -4):

This can be calculated without using the distance formula.

The distance between both vertices = |9 -(-1)| = 10 units

Distance between (-1, -4) and (4, 8):

[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] (-1, -4) = (x_1, y_1) [/tex]

[tex] (4, 8) = (x_2, y_2) [/tex]

[tex] d = \sqrt{(4 -(-1))^2 + (8 - (-4))^2} [/tex]

[tex] d = \sqrt{(5)^2 + (12)^2} [/tex]

[tex] d = \sqrt{25 + 144} = \sqrt{169} [/tex]

[tex] d = 13 units [/tex]

Distance between (9, -4) and (4, 8):

[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] (9, -4) = (x_1, y_1) [/tex]

[tex] (4, 8) = (x_2, y_2) [/tex]

[tex] d = \sqrt{(4 - 9)^2 + (8 - (-4))^2} [/tex]

[tex] d = \sqrt{(-5)^2 + (12)^2} [/tex]

[tex] d = \sqrt{25 + 144} = \sqrt{169} [/tex]

[tex] d = 13 units [/tex]

Perimeter = 10 + 13 + 13 = 36 units

Answer:

Neither

Step-by-step explanation:

Parallel lines have the same gradient while the product of the gradients of perpendicular lines is -1.

Let's find the gradient of each line first.

[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }[/tex]

[tex]gradient \: of \: first \: line \\ = \frac{1 - ( - 2)}{3 - ( - 2)} \\ = \frac{1 + 2}{3 + 2} \\ = \frac{3}{5} [/tex]

[tex]gradient \: of \: the \: other \: line \\ = \frac{5 - ( - 6)}{5 - 4} \\ = \frac{5 + 6}{1} \\ = 11[/tex]

Product of the gradients

= 11 ×⅗

= 6.6

Since the gradients are neither the same, nor do the product of the gradients equal to -1, the 2 lines are neither parallel or perpendicular to each other.

Answer:

5 and 24

Step-by-step explanation:

1) replace the x's with 125 | c(x)=120+4(125)/(125)

620/125=5 simplify numerator

x=5

2) replace c(x) with 9 | 9=120+4x/x

9x=4x+120 multiply both sides by x

9x-4x=4x+120-4x subtract both sides by -4x

5x=120 divide both sides by 5

x=24

so, it costs about 5 dollars per book when 125 are printed

and, if it costs 9 dollars per book, 24 should be printed

The given function for the cost of printing is a linear function that has a

fixed (set up) cost and a variable cost component.

The correct responses are;

Reasons:

Given that the function for the cost of printing x books is; c(x) = 120 + 4·x, we have;

1. The cost of printing 125 books is c(125) = 120 + 4 × 125 = 620

2. The amount the author plans to charge per book = $9

The number of books, n, that should be printed is given as follows;

[tex]\displaystyle 9 = \mathbf{ \frac{120 + 4 \times n}{n}}[/tex]

Which gives;

9·n = 120 + 4·n

9·n - 4·n = 120

5·n = 120

[tex]\displaystyle n = \frac{120}{5} = \mathbf{24}[/tex]

The number of books that should be printed, n ≥ 24 books
