At the Atkins County Fair, the crowd for a concert by The Cooper Band cannot exceed a certain number. The limit for the number of people who can attend the concert is 0.04 people per square foot of space in the arena. If the arena is shaped as a rectangle with sides 220 feet by 200 feet, how many people can attend the concert?

Answers

Answer 1

The first thing to do was to find the area of the space to do that we would need to do:
220*200= 44000
the area is [tex]44000ft^{2} [/tex]
next you would do:
44000/.4 to find how many people can fit
this equals 11000
11,000 people can attend the concert

I spent 25 Points, PLEASE HELP! In a graph, x represents the number of months since a business opened, and y represents the total amount of money the business has earned. The following three points are from the graph:
(2, 1990) (5, 4225) (9, 7205)

Find the slope and y-intercept. Explain what each represents.

Answers

First find the slope. m=(y2-y1)/(x2-x1)

m=(4225-1990)/(5-2)=745,

m is the slope, this represents the amount of money earned each month that the business operates.

so far we have:

y=745x+b, using any point we can solve for b, I'll use (2,1990)

1990=745(2)+b

1990=1490+b

500=b

b is the y-intercept which is $500, it represents the amount of moeny that the business started with.

The slope of this scenario is 745. The slope represents the profit made each month.

Step-by-step explanation:

Assuming that the equations define x and y implicitly as differentiable functions x=f(t),y=g(t) find the slope of the curve x=f(t), y=g(t) at the given value of t x(t+1)-4tsqrt(x)=9, 2y+4y^3/2=t^3+t , t=0

Answers

The given equations are
[tex]x(t+1)-4t \sqrt{x} =9[/tex] (1)
[tex]2y+4y^{3/2}=t^{3}+t[/tex] (2)

When t=0, obtain
[tex]x=9 \\ 2y+4y^{3/2}=0 \,\,=\ \textgreater \ \, y(1+2 \sqrt{y} )=0 \,=\ \textgreater \ \,y=0[/tex]

Obtain derivatives of (1) and find x'(0).
x' (t+1) + x - 4√x - 4t*[(1/2)*1/√x = 0
x' (t+1) + x - 4√x -27/√x = 0
When t=0, obtain
x'(0) + x(0) - 4√x(0) = 0
x'(0) + 9 - 4*3 = 0
x'(0) = 3
Here, x' means [tex] \frac{dx}{dt} [/tex].

Obtain the derivative of (2) and find y'(0).
2y' + 4*(3/2)*(√y)*(y') = 3t² + 1
When t=0, obtain
2y'(0) +6√y(0) * y'(0) = 1
2y'(0) = 1
y'(0) = 1/2.
Here, y' means [tex] \frac{dy}{dt} [/tex].

Because [tex] \frac{dy}{dx} = \frac{dy}{dt} / \frac{dx}{dt} [/tex], obtain
[tex] \frac{dy}{dx} |_{t=0}\, = \frac{1/2}{3}= \frac{1}{6} [/tex]

Answer:
The slope of the curve at t=0 is 1/6.

Final answer:

To find the slope of the curve at a given value of t, differentiate the implicit equations x=f(t) and y=g(t) with respect to t, then substitute the given t value into the derivatives to find the slopes.

Explanation:

Slope of the curve at the given value of t:

Given equations: x(t+1)-4tsqrt(x)=9 and 2y+4y^3/2=t^3+t, t=0Differentiate the equations x and y with respect to t to find dx/dt and dy/dtSubstitute t=0 into the derived dx/dt and dy/dt to find the slopes at the given value of t

Solve 2 cos theta + 2 = 3 in the interval from 0 to 2pi. Round to the nearest hundredth.

Answers

2cos theta = 1 -> cos theta = 1/2

Then theta = pi/3 + 2npi or -pi/3 + 2npi, where n is random interger

And the domain is restricted in [0,2pi]

So answer will be pi/3 or 5pi/3

Final answer:

The solutions to the equation 2 cos θ + 2 = 3 in the interval from 0 to 2π are θ = π/3 and θ = 5π/3, which approximate to 60 degrees and 300 degrees.

Explanation:

The equation given is 2 cos θ + 2 = 3. To solve this equation, first subtract 2 from both sides to get 2 cos θ = 1. Then, divide both sides of the equation by 2 to isolate cos θ, yielding cos θ = 0.5.

In the interval from 0 to 2π (0 to 360 degrees), cos θ = 0.5 occurs at θ = π/3 and θ = 5π/3 (60 degrees and 300 degrees), as these are the angles in the first and fourth quadrants where the cosine value is positive and equal to 0.5.

Therefore, the solutions to the equation are θ = π/3 (θ ≈ 1.05 radians) and θ = 5π/3 (θ ≈ 5.24 radians), or θ ≈ 60 degrees (θ ≈ 1.05) and θ ≈ 300 degrees (θ ≈ 5.24) when rounded to the nearest hundredth of a radian.

What is the perimeter of the rectangle?

Answers

102/17 = 6

Answer:

(Really really really sorry if this incorrect)... ok so it's 17 cm tall in length. That would be 17 blocks high, for example. The area is 102, so 102 cm2 divided in half equals 51, so the width would be 51 cm. So the perimeter is 17 + 17 + 51 + 51 = 136 cm.

Use a table of function values to approximate an x-value in which the exponential function exceeds the polynomial function. f(x) = 5x + 4 h(x) = x2 + 8x + 24

x = -3
x = 3
x = 4
x = 5

Answers

The exponential function is [tex]f(x)= 5^{x} +4[/tex]
The polynomial function is [tex]h(x)= x^{2} +8x+24[/tex]

We want a value of x as such that [tex]f(x)\ \textgreater \ h(x)[/tex], so

[tex] 5^{x}+4 [/tex] > [tex] x^{2} +8x+24[/tex]

We are provided with four possible value of x. By process of trial and error, we will narrow down two values of x when the statement is changing from false to true

first, we try [tex]x=-3[/tex] by substituting into [tex]f(x)[/tex] and [tex]h(x)[/tex]

[tex] f(-3)=5^{-3}+4 = 4.008 [/tex] and [tex]h(-3)= (-3)^{2}+8(-3)+24=9 [/tex]
so [tex]f(x)[/tex]>[tex]h(x)[/tex] which is not the inequality wanted

We try [tex]x=3[/tex] by substituting into [tex]f(x)[/tex] and [tex]h(x)[/tex]
[tex]f(3)= 5^{3}+4=129 [/tex] and [tex]h(3)= (3)^{2}+8(3)+24=57 [/tex],
so [tex]f(x)[/tex] > [tex]h(x)[/tex] as wanted

We know that any values of [tex]x[/tex] greater than three will give [tex]f(x)[/tex] greater than [tex]h(x)[/tex], so we narrow down to two values that make the statement changes from false to true.

There is one value between -3 and three that makes [tex]f(x)[/tex] greater than [tex]h(x)[/tex]. From here we use the method of trial and error.

We can start with the mid value between -3 and three which is 0
[tex]f(0)= 5^{0}+4=5 [/tex]
[tex]h(0)= 0^{2}+8(0)+24=24 [/tex]
[tex]f(x)[/tex] is less than [tex]h(x)[/tex] which isn't the inequality we want so here we narrow down the value of x must be between 0 and 3

We can try mid-value between 0 and three which is 1.5
[tex]f(1.5)= 5^{1.5}+4=15.18 [/tex]
[tex]h(1.5)= (1.5)^{2}+8(1.5)+24=38.25 [/tex]
[tex]f(x)[/tex] is still less than [tex]h(x)[/tex], so we now narrow down the value of x between 1.5 and 3

We try again using the mid-value between 1.5 and three which is 2.25
[tex]f(2.25)= 5^{2.25}+4=41.38 [/tex]
[tex]h(2.25)= 2.25^{2}+8(2.25)+24=47.0625 [/tex]
We still have [tex]f(x)[/tex] less than [tex]h(x)[/tex] so we can narrow down further the value of x between 2.25 and 3 (which is quite a short interval already)

We can keep trying by choosing a value of x says x=2.6
[tex]f(2.6)= 5^{2.6}+4=69.66 [/tex]
[tex]h(2.6)= 2.6^{2}+8(2.6)+24=51.56 [/tex]
We have [tex]f(x)[/tex] greater then [tex]h(x)[/tex]

The narrowing down process continues where we now have the interval of x between 2.25 and 2.6. Keeping to one decimal place we can find the
value of x=2.4 is the approximate value where [tex]f(x)[/tex] is greater than [tex]h(x)[/tex].

Answer: x=2.4

The correct answer is x = 5.

Find the equation of the parabola whose vertex is the origin and whose directrix is x=-4

Answers

Answer:

Step-by-step explanation:

2020 2021

Equation of the parabola whose vertex is the origin and whose directrix is x=-4 is x=0.

What is Parabola?

A parabola is a curve where any point is at an equal distance from: a fixed point (the focus ), and; a fixed straight line (the directrix )

As we have vertex at the origin i.e. (0,0) and directrix is x=-4 and a line parallel to y-axis,

it must have a focus at (4,0)

Equation of the parabola represents locus of a point (x, y), which moves so that its distance from x=-4 to (4,0) are equal.

Hence, equation of parabola is

(x-4)²+(y-0)²=(x+4)²

(x-4)²+y²=(x+4)²

x²+16-8x=x²+16+8x

-16x=0

x=0

Hence, equation of the parabola whose vertex is the origin and whose directrix is x=-4 is x=0.

Given:

n = the sample size.
t* is provided by the t-table.
