A 6-kg bowling ball sits on top of a building that is 120 meters tall.

Answers

Answer 1

The potential energy of the ball will be 7200 Joules.

What is potential energy?The energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.For small height changes, gravitational potential energy can be computed using -  E = mgh.

Given is a 6-kg bowling ball sits on top of a building that is 120 meters tall.

We can write the potential energy of the ball as -

E = mgh

A plate of spring roll is price of $7.5.

What is Linear System?

A linear system is a mathematical representation of a system in systems theory that relies on the application of a linear operator. Compared to nonlinear systems, linear systems often have significantly simpler traits and properties.

Let n, b, and c represent the cost per plate of spring roll, chicken tenders , and pretzel dipper, respectively.

One party spends $23 and purchases two plates of chicken tenders and one plate of pretzel dipper.

i.e. 2b + 1c = 23

     2b + c = 23                                        --------------------- 1

Three plates of  spring roll and a plate of chicken tenders are purchased by another group for $30.75.

That is

          3n + 1b = 30.75

          3n + b = 30.75                                          ---------------------- 2

A third party spends $22.25 and purchases one of each appetizer.

That is

             n + b + c  = 22.25                                    --------------------- 3

On solving;

eqn2 - eqn3

            2n - c = 8.5                                           --------------------- 4

on solving;

eqn 1 + eqn 4

             2b+ 2n = 31.5

             b + n = 15.75                                           --------------------- 5

On solving;

eqn 3 - eqn 5

              c = 6.5

Substituting in eqn 4

           2n - 6.5 = 8.5

              n = 7.5

Substituting in eqn 3

           7.5 + b + 6.5  = 22.25

               b = 8.25

Given g(x) = − 4x + 8, identify the domain, range, and x-intercept of the function. Domain: −∞ < x < ∞; Range: −∞ < y < ∞; x-intercept (2, 0) Domain: −∞ < x < ∞; Range: −∞ < y < ∞; x-intercept (−2, 0) Domain: −4 < x < 8; Range: − 4 < y < ∞; x-intercept (2, 0) Domain: −4 < x < 8; Range: −∞ < y < 4; x-intercept (−2, 0)

Answers

the domain, range, and x-intercept of the function g(x) = − 4x + 8 are Domain: −∞ < x < ∞; Range: −∞ < y < ∞; x-intercept (2, 0) that is the first option.

What is the function?

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

Given a function  g(x) = − 4x + 8

The domain of a function means all possible inputs or all the numbers that can be put in place of x to get some output

The range of a function means all possible outputs or all the numbers that are the result of all the inputs or values of y

Intercept is the point on a graph whose one coordinate is zero. There are two types of intercepts - X intercept where the y coordinate is zero and Y-intercept where the value of the x coordinate is zero

The domain of the given function is all real numbers or - infinite < x< infinite

The range of the given function is all real numbers or - infinite < x< infinite

The x-intercept of the given function is where y = 0

so,  0 = -4x + 8

-8 = -4x

x = 2

The x-intercept is (2,0)

Therefore, the domain, range, and x-intercept of the function g(x) = − 4x + 8 are Domain: −∞ < x < ∞; Range: −∞ < y < ∞; x-intercept (2, 0) that is the first option.

The variable X varies jointly with Y and Z. When Y = 2 and Z = 4, X = 14. What is the value of X when Y = 10 and Z = 16?

Answers

The value of x  when y = 10 and Z = 16, in the given joint variation is: 1120.

How to Solve a Joint Variation Problem?

If X varies jointly with Y and Z, then we can use the formula X = k * Y * Z, where k is the constant of proportionality.

Using the given information, we can find k by plugging in the values of Y, Z, and X and solving for k:

14 = k * 2 * 4

k = 14 / (2 * 4)

k = 7/2

Now that we know the value of k, we can use it to find the value of X when Y = 10 and Z = 16:

X = k * Y * Z

X = (7/2) * 10 * 16

X = 70 * 16

X = 1120

So the value of X when Y = 10 and Z = 16 is 1120.

For the graph with points (-2, 2) and (2,0), the slope, linear equation and y-intercept is m = -1/2, y = -1/2x + 1 and y = 1 respectively.

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The first graph shows the points (-2, 2) and (2,0).

The slope-intercept form of an equation/function is - y = mx + b

To find the slope m use the formula -

(y2 - y1)/(x2 - x1)

Substituting the values in the equation -

[0 - 2]/[2 - (-2)]

(-2)/(2 + 2)

-2/4

-1/2

So, the slope point is obtained as m = -1/2.

The equation becomes - y = -1/2x + b

To find the value of b substitute the values of x and y in the equation -

2 = -1/2(-2) + b

2 = 1 + b

b = 2 - 1

b = 1

So, the value for b is 1.

Now, the equation becomes -

y = -1/2x + 1

To find the y-intercept substitute the value of x = 0 in the equation -

y = -1/2(0) + 1

y = 0 + 1

y = 1

Therefore, the slope is 1, equation is y = -1/2x + 1 and y-intercept is y = 1.

The probability of landing on orange is equal to the probability of landing on yellow.
The probability of landing on purple is equal to the probability of landing on yellow.

Answers

The correct statement is : The probability of landing on purple is equal to the probability of landing on yellow.

What is probability?

Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening is equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes

Given here: A spinner with four different colors purple, yellow, blue and orange.

Now Section 1&8 = Blue

Section 2&3 = yellow

Section 4,5,6 = blue

Section 7 = orange

Total=8

Thus probability for each section are as follows

P(purple)=2/8

           =1/4

P(yellow)=2/8

              1/4

P(Blue)=3/8

P(orange)=1/8

∴ The probability of landing on purple is equal to the probability of landing on yellow.

Hence, The probabilities of all the individual sections are 1/4,1/4,3/8,1/8 for purple, yellow, blue and orange respectively.

Each bag of lemons costs $3.99

Let m represents the cost of eggs and n represents the cost of each bag of lemons.

He buys 6 bags of lemons that each cost the same amount.

so, the cost of six bags of lemons would be 6n

He pays a total of $29. 33

so, we get an equation,

m + 6n = 29. 33               ............(1)

Levi pays a total of $5. 39 for the eggs

So, m = 5.39

We need to find the value of n.

substitute above value of m in equation (1)

m + 6n = 29. 33

5.39 + 6n = 29. 33

P ( A / B ) = P( A∩B ) = 55/107 = 0.5140

P ( B ) = ( 55 + 32 ) / 107 = 0.8131

Hence P ( A / B ) = 0.5140 / 0.8131 = 0.6322

A = failure due to electrical

B = failure due to gas leak

C)  Probability of a gas leak given that there is evidence of electrical failure

P ( B / A ) =  P ( B ∩ A ) = 0.5140

P( A ) = ( 55 + 17 ) / 107  = 0.6729

Hence P ( B / A ) = 0.5140 / 0.6729 = 0.7639

Answers

Answer:

  (a)  A(x) = (12 -2x)√(3x -9)

Step-by-step explanation:

You want a formula for the area (a(x)) of an isosceles triangle with congruent sides of length x and perimeter 12. You also want its maximum value, and a graph and the maximum value of z = 2a(3x+3)+1.

(a) Heron's formula

Heron's formula for the area of a triangle with side lengths a, b, c is ...

  A = √(s(s -a)(s -b)(s -c)) . . . . . . where s = (a+b+c)/2, the semiperimeter

Given a perimeter of 12, and two sides x, this becomes ...

  A(x) = √(6(6 -x)(6 -x)(6 -(12-2x))) = √(6(6 -x)²(2x -6))

  A(x) = 2(6 -x)√(3(x -3)) . . . . . . factor out perfect squares

  A(x) = (12 -2x)√(3x -9) . . . . . . domain: 3 ≤ x ≤ 6

The domain is such that the radical and the area are non-negative.

(b) Maximum

The derivative of the area function is ...

  [tex]A'(x)=-2\sqrt{3x-9}+\dfrac{3(6-x)}{\sqrt{3x-9}}=\dfrac{-2(3x-9)+3(6-x)}{\sqrt{3x-9}}\\\\A'(x)=\dfrac{-9x+36}{\sqrt{3x-9}}[/tex]

The derivative is zero at the maximum, so ...

  -9x +36 = 0   ⇒   x = 4 . . . . . . . an equilateral triangle

The maximum area is ...

  A(4) = (12 -2·4)√(3·4 -9) = 4√3

The maximum area is 4√3.

Since the maximum of A(x) is 4√3 at x=4, the maximum of 2A(3x+3) +1 will be ...

  2(4√3) +1 = 8√3 +1 . . . . . . . where 3x+3 = 4  ⇒  x = 1/3

The maximum of 2A(3x+3)+1 is 8√3 +1 at x = 1/3.

(c) Scaled and translated

The function ...

  z = 2A(3x+3) +1 = 2A(3(x+1)) +1

Compare this to ...

  z = p·A(q(x -r)) +s

which is vertically expanded by p, horizontally compressed by q, then translated right r and up s.

We see that the parent function A(x) is vertically expanded by a factor of 2, compressed horizontally by a factor of 3, then translated left 1 and up 1.

Applying these transformations to the original A(x) domain and range, we find the domain is ...

  1/3[3, 6] -1 = [0, 1] . . . . . domain of z

And the range is ...

  2[0, 4√3] +1 = [1, 8√3 +1] . . . . . range of z
